Authors:   Al-Farabi  Kazakh  National  University, Makhashbaevna Almagambetova  Aliya
Published: October 2023

The article is devoted to a historiographical review of the works of modern foreign authors on the problems of Qarakhanid-Chinese relations. The author of the article has studied the works of the last twenty years published in reputable foreign editions. Such works include scientific articles, monographs written in English. The purpose of this article is to analyze the problems in the study of interstate relations between the Qarakhanid State and the Chinese Empire in the Late Middle Ages. The author of the article managed to highlight the main issues of the Turkic-Chinese relations considered by foreign authors. The main methods used are general scientific methods, as well as comparative, historical and genetic methods and critical types of analyses.As a result of the conducted research, the following results were obtained: Chinese sources confirm the information that was presented in the Arab-Persian sources and do not contribute more detailed or new information to the study of this issue. Moreover, there are a number of issues in these Qarakhanid-Chinese relations that require further research. Of particular interest is the question of gifts and goods that circulated between States, through which the essence and purpose of the desired relations are also manifested. A certain list of gifts or goods and their purpose demonstrate the nature of the relations between the Parties, which in turn affects the further course of events. The analyzed English-language works can be used in the study of the problems of the foreign policy of the Qarakhanid State, in the study of the trade routes of the Great Silk Road and in the analysis of the role of the Qarakhanids between the Muslim and Chinese worlds.

Published: October 2023

The folklore of the Turkic peoples is extremely rich and diverse. In terms of genre, the Turkic epics are of considerable interest, which, being transmitted orally and in writing from generation to generation and which reveal the spiritual wealth and culture of the Turkic peoples. Heroic epics depicting historical facts, events, and martial traditions of the Turkic peoples are indicative in this context. The origins of heroic epics go back to ancient myths, heroic fairy tales, ancient legends, where mythological consciousness undergoes significant mental changes in the formation of heroic epics.Mythological motifs can be traced in heroic epics of the Turkic peoples of Southern Siberia, that represent a complex synthesis of ancient beliefs of the Turkic peoples, and the epics themselves glorify the glorious exploits of the Turkic peoples, many of which have a real historical basis.This article highlights the history of the epics (including heroic) of the Turkic peoples of Siberia, their systematic classification by origin, subject matter, plot composition, genre characteristics is carried out, plot motives, including mythological ones, are identified. It is assumed that shamanic myths are at the structural basis of the epics of the Turkic peoples of Siberia, as a result of which the structural frame and the plot of events in the myths are repeated in the epics together with various semantic changes.

The seals used by the authorities in the history of Kazakhstan before the twentieth century can be grouped and systematized as follows: seals with archeographic symbols; seals with patterns, 90Т. Картаева, Е. Даубаев, Э. Алтынбекова Turkic Studies Journal 2 (2023) 67-92pictorial signs; seals with a portrait image; coat of arms seals; seals with stamps without the name of the owner; stamps with the name of the owner; relief seals without the name of the owner; relief seals with the name of the owner.Although Kazakh khans and sultans stamped their seals in the form of rings, they did not wear them on their hands every day, and when certifying documents, the pedestal was worn on the finger in the «aynateris» way, i.e. with a pointed head up (a bird’s nose is negative when wearing a «kusmuryn» ring) or certified with holding the pedestal in the hand. But judges, rich people, volost governors, tarkhans, batyrs and elders had round, convex, square or stone seals. The shape, that is the image of the ring seal of the Khans and sultans, corresponded to the image of the top of the military banners. The pommel of the banner and the seal are the attribute of power. The fact that the head part of both attributes of power is directed upwards proves that they were generally recognized in the traditional environment. The originals (originals) of the seals of the Kazakh Khans and sultans have not been preserved under the influence of colonization. The authors share their experience in reconstructing the seal and revealing the mystery of the symbols on the front of the seal.

The article deals with the problem of studying syntagma in relation to phonetics, vocabulary, semantics, intonation, also highlights the issue of classification of syntagma by scientists in the form of a phonetic unit, semantic-intonation unit, multicomponent syntagma, one-component syntagma, lexical syntagmatics, syntactic syntagmatics, it is shown that it is not part of a a single system, and the connection of syntagma with the specified areas is recognized as a linguistic unit of the sentence. The sentence is formed from the words that have fallen into the flow of speech, and the syntagma is a syntactic category that serves to convey thought, determining the role and meaning 134Н.А. Ильясова, Г.А. Еркегалиева Turkic Studies Journal 3 (2023) 123-135of the words that come into contact within a sentence. As a result, the term syntactic syntagma is proposed. Syntactic syntagma refers to a category that has a grammatical status closely related to the structural, semantic, intonation, and communicative system of the language. During the analysis of the activity of interrelated words and linguistic units linking them within a sentence, it is proved that there is a connection between syntactic syntagma and the structural system of the language. The semantic compatibility of words as part of a syntactic syntagma is considered through the relationship of the semantic field with the lexical meaning. Intonation pause and consecutive intonation serve to link syntactic syntagma and intonation. The connection between communication and syntagma is reflected in the definition of information meanings. A comprehensive analysis of each syntagma is carried out, which serves to convey certain information, as well as the function of words and affixes as part of a syntactic syntagma, the features of the interaction of syntactic syntagmas and syntagmatic connections. Syntactic syntagma is considered as a grammatical category arising from the connection of words in the flow of speech.

The article addresses to the study of the legal status peculiarities of those sentenced to life imprisonment. The authors indicate that peculiarities regarding the legal status of persons sentenced to life imprisonment differ greatly, but they believe that the most successful is the basic model of the structure, which is called traditional in science: subjective rights, legal interests and duties of convicts. The rights of those sentenced to life imprisonment are set out in Art. 107 and Art. 151 of the Criminal and Executive Code of Ukraine. While analyzing the petition of Luzhynetskyi A.O. to the Constitutional Court of Ukraine regarding the granting of the right to short-term travel outside the prisons to those sentenced to life imprisonment, the authors came to the conclusion that it is not appropriate to grant such a right. The author points out that the institution of punishment in the form of life imprisonment is undergoing significant changes, however, in the opinion of the authors, it is not appropriate to grant this category of convicts the right to short-term departures from prisons: First, those sentenced to life imprisonment enjoy all the rights provided for those sentenced to imprisonment for a certain period of time, with the exception of those restrictions prescribed for them based on the gravity of the crime committed and its criminal activity. Second, those sentenced to imprisonment do not have the right to leave the prison for a short time. This permission can be granted only by the head of the institution, under exceptional circumstances, if the convict is not inclined to continue his illegal activities and proves his correction. This category of convicts is the most dangerous in connection with the severity of the crime committed, the severity of the punishment, and the impossibility of applying a more severe punishment than that provided for by the previous criminal activity. Third, in the case of correction of a person sentenced to life imprisonment, such elements of the progressive system of execution of punishments may be applied to him, such as replacing life imprisonment with imprisonment for a certain period, and in the future, conditional early release. Key words: convict, life imprisonment, deprivation of liberty, legal status, material, household and health care support, vacation, short-term departure, penitentiary institution, change of conditions of detention, prevention.

The focus of metrological science on accuracy as a key property of measurement information (MI) does not meet the needs of practice, which are much broader and include reliability, timeliness, completeness and other properties. Recently, these properties are included in metrological standards, but this is more a declaration than real practice. It is shown that there are contradictions between accuracy and other properties of MI. To involve them into metrology is possible by changing the logic and coordinate system, with the inclusion of an optimal control solution and an action leading to a result like Shewhart-Deming cycles.

The work presents the results of a study of the cycloalkylation reaction of phenol with 1-methylcyclopentene and the calculation of a regression mathematical model of the process. KN-30 was used as a process catalyst. The effect of input factors (temperature, time, molar ratios of starting components and amount of catalyst) on the yield and selectivity of para-(1-methylcyclopentyl) phenol was studied. As a result, the optimal conditions for obtaining para-(1-methylcyclopentyl) phenol with high yield and selectivity were found. When studying the reaction of cycloalkylation of phenol with 1-methylcyclopentene in the presence of a KH-30 catalyst, it was found that a high yield of the target product of 71.2% (for taken phenol), a selectivity of -92.8% (for the target product) was obtained under the following conditions: temperature - 110 ° C, duration reactions - 5 hours, the molar ratio of phenol to 1-methylcyclopentene 1:1, the amount of catalyst 10% based on the taken phenol. The chemical structure of the synthesized para-(1-methylcyclopentyl) phenol was confirmed by IR, 1Н and 13С NMR methods and its physicochemical parameters were determined. A regression mathematical model of the cycloalkylation process was calculated and the parameters of the optimal mode were found. With the calculated optimal values of the input variables found, a control experiment was set up, which made it possible to find the yield values of the target product Y1=78%, which indicates the acceptability of the developed regression model.

Financing for sustainable food systems: The role of the vending sector
Authors: Bertossi Alberto , Troiano Stefania , Marangon Francesco
Published: October 2023

The agribusiness sector needs substantial funding to initiate an ecological transition involving healthy diets and the creation of local circuits and linkages. One sector that has yet to be studied from this perspective is vending, whose importance is confirmed by its profits, especially in Italy. At present, the vending sector cannot be considered sustainable as it rarely contributes to the development of healthy diets and local economies with low environmental impact. There are cases of products with suitable characteristics that can push the sector towards more sustainable dynamics, but such products often do not achieve the success they deserve for various socioeconomic reasons. Access to financial investment or alternative modes of financing could help small and medium-sized enterprises in the sector overcome these difficulties.

Published: October 2023

This paper aims to demystify a lot of misconceptions still widely circulating today about the alleged properties of blockchain and then illustrate the real opportunities that this technology offers for "food system" and how it must be correctly implemented for it to be truly useful, for producers and consumers, particularly in the agrifood sector. The concepts of blockchain opportunities and incompleteness of agri-food chain projects based on blockchain technology are then explained, setting out the minimum and necessary characteristics required to make the use of this technology useful and effective (Minimum Viable Ecosystem). The process governance levels for the development and maintenance of a blockchain traceability project are then illustrated, focusing on the role and responsibility of each player in the supply chain.Finally, the structure of a blockchain solution is described, focusing on a number of structural and technological solutions by outlining the concepts of consistency checking for the validation of input data with appropriate smart contracts, and of information frameworks for the subsequent scrutiny of data in audit operations and the assignment of levels of reliability.These are essential prerequisites for a collaborative blockchain data management to pursue the objective of actual reliability and transparency of information.
Las fortalezas humanas desde la perspectiva de género: un estudio exploratorio en población española
Authors:   Instituto Europeo de Psicología Positiva, Ovejero Bruna Ma. Mercedes , Cardenal Hernáez Violeta ,   Universidad Complutense de Madrid
Published: October 2023

La psicología positiva es el estudio científico del funcionamiento psicológico óptimo. Desde una perspectiva práctica pretende conocer y analizar las condiciones, procesos y mecanismos que conducen a una vida plena. En el año 2004 se publicó el libro que estableció las bases para el estudio de las fortalezas humanas. Character Strengths and Virtues es la otra cara de la moneda, un Manual para clasificar el potencial humano y la pieza que faltaba en el modelo psicopatológico tradicional. El Manual propone que hay 24 fortalezas y 6 virtudes. El modelo Values In Action (VIA-IS) es también una nueva forma de evaluar los rasgos positivos de las personas. Empleado en esta investigación, VIA-IS (Peter & Seligman, 2004) es un cuestionario que evalúa detalladamente cada una de las fortalezas de la propuesta. Los estudios realizados con este modelo muestran que existen diferencias entre hombres y mujeres en las fortalezas, aunque no se tiene todavía evidencia empírica suficiente, y no se conoce de un solo estudio que analice la relación entre los roles de género y las fortalezas. Por lo tanto, se considera de importancia analizar si las diferencias sociales entre hombres y mujeres están influyendo en las fortalezas humanas. Este estudio utiliza el cuestionario de Mahalik et al. (2003; 2005): CFNI (para mujeres) y CMN (para hombres). Las principales conclusiones a las que se llega con este trabajo confirman la existencia de diferencias entre hombres y mujeres en algunas fortalezas humanas, considerando el tamaño del efecto de estas diferencias entre pequeño y moderado. En el caso de la feminidad, existen relaciones positivas entre este constructo y las fortalezas humanas; en el caso de la masculinidad, las relaciones son negativas.
The polyelectrolyte behavior of randomly branched lignosulfonates
Authors: MYRVOLD BERNT O.
Published: October 2023

Lignosulfonates are formed by the random breaking of the “infinite” lignin network in wood, resulting in smaller sulfonated fragments. The resulting lignosulfonate molecule might be best described as a randomly branched polyelectrolyte. In this study, the scaling laws for polyelectrolyte expansion for this model are derived, as well as scaling laws for other models for lignosulfonate. The author also compares scaling laws with experimental values. The polyelectrolyte expansion is in quantitative agreement with the randomly branched polyelectrolyte model, but it disagrees with the microgel models. The temperature dependence of the randomly branched polyelectrolyte model is in qualitative agreement with experimental results.
Effects of sheet moisture and calender pressure on PCC and GCC coated papers
Authors: DIMMICK AMY C.
Published: October 2023

Previous work demonstrated that narrow distribution coating PCC allows high moisture calendering with no loss of optical properties of coated papers. Broad particle size distribution pigments exhibit a significant loss of optical properties, when moisture increases and supercalendering pressure is adjusted to achieve a gloss target. In this study, we rationalize these results by considering macro- and micro-smoothness and demonstrating that narrow distribution coating PCC produces high micro-smoothness even in the absence of supercalendering. Calendering is necessary only to supply macro-smoothness through base paper deformation. Therefore, at high moisture, pressure can be reduced so that no additional base paper deformation occurs and optical and physical properties of the final coated paper are equivalent to those achieved with lower moisture and higher pressure.
Blade, film, and curtain coating techniques and their influence on paper surface characteristics
Authors: ENDRES ISABEL , TIETZ MARTIN
Published: October 2023

Curtain coating is a promising high-precision coating technique with a wide variety of possible applications. It has been used in the production of specialty papers since the 1990s and is now being introduced for the production of graphic paper and board grades. This study compares the curtain coating technique with the more traditional blade and film coating techniques with regard to the surface characteristics of the coated paper. A 38-g/m2 lightweight coated (LWC) base paper was pilot-coated using the three different coating techniques. The coated papers were studied using a combination of novel and traditional surface characterization methods with respect to a number of paper properties, including optical properties, roughness, coat weight distribution, and compression uniformity. We found that curtain coating gave the most uniform coat weight, but at the same time the roughest surface. Because of the gentle application of the coating onto the base paper, the bulk was well preserved, and the paper was more compressible than both the blade- and film-coated papers.
El jardín de al lado de José Donoso como novela-espejo
Authors: Vilches Pino Emilio Andrés
Published: October 2023

El presente ensayo propone que la novela El jardín de al lado de José Donoso puede ser leída desde sus espacios heterotópicos. Dos de ellos son las ventanas, a través de las que los personajes miran el jardín vecino, y también los espejos. Ambos espacios no solo son capaces de superponer en una sola imagen temporalidades y espacialidades distintas, sino que además reflejan y completan la subjetividad del observador. Las ventanas, como pantallas de cine o como espejos, son entonces espacios heterotópicos que inciden directamente en la lectura de la obra. En su dimensión simbólica, la novela completa puede ser leída como un espejo que refleja una realidad invertida del sujeto.
Do NSAIDs and Other Pain Relief Drugs Can Inhibit the Growth of Lactobacillaceae?
Authors: Kruszewska Hanna , Zawistowska-Rojek Anna , Tyski Stefan
Published: October 2023

Non-steroidal anti-inflammatory drugs (NSAIDs) commonly used in clinical practice may cause gastrointestinal injuries and influence the gut microbiota. This study investigated the effects of various NSAIDs and some analgesics on the viability of Lactobacillaceae strains (including probiotic strains) in vitro. It was found that diclofenac, ibuprofen, ketoprofen, dexketoprofen, flurbiprofen, and acetylsalicylic acid inhibited the growth of lactobacilli at a concentration of 0.05−3.2 mg/ml. These MICs of NSAIDs are well above therapeutic plasma concentrations achieved in humans, indicating that the tested drugs should not inhibit the growth of lactobacilli in the human digestive tract.
Preparation of Highly Porous Scaffolds with Controllable Pore Size from Microbial Polyesters
Authors: Polyák Péter , Tóth Ágoston , Tátraaljai Dóra
Published: October 2023

Microbial polyesters saw limited use in the field of tissue engineering, even though the biocompatibility of these polymers makes them ideal candidates for this role. The primary factor that hinders the proliferation of microbial polyesters in this market is that their processing with conventional techniques, such as electrospinning or 3D printing, is challenging. However, the full potential of these biopolymers could still be utilized by applying unconventional manufacturing methods, such as those based on the concept of salt leaching. An implementation of this concept facilitates the production of scaffolds that simultaneously have high porosity and excellent permeability. Moreover, the average pore size can also be varied in the range from 50 to 400 µm, which was reported to be optimal for the cultivation of eucaryotic cell cultures. By adjusting the pore size, the scaffold can be tailored to the eucaryotic cells the tissue consists of. Furthermore, we have developed an entirely new computational method for the approximation of the pore size distribution of the scaffolds. The method relies on 3D data reconstructed by the software of a digital optical microscope and also facilitates the modeling of the average pore size of scaffolds. Thus, besides the control of the pore size, our method enables its prediction as well.
Finite Element Analyses of Cast-in-situ RC Flat Slab with an Equivalent Frame for Horizontal Loads
Authors: Roszevák Zsolt , Haris István
Published: October 2023

In structural construction practice, the use of reinforced concrete slabs is extremely common due to their structural and economic advantages. An important issue is the study of structural behavior given to horizontal effects. The significance of this is centered not only on the scales caused by wind and construction loads, which are considered to be “normal” i.e., the quasi-static, which is essentially one-way monotonically increasing but also the most researched seismic, i.e., cyclically varying, direction and magnitude effects. The most widespread methods for sizing flat plate slabs to unidirectional, quasi-static horizontal loads are the so-called Equivalent Frame Method and the Effective Beam Width Method. In addition to analytical and basically linear numerical theoretical methods, several laboratory experiments have been performed and published. In this paper, we investigate the behavior of column-supported flat plate slabs against unidirectional, monotonically increasing horizontal loads using an advanced nonlinear numerical modeling method. Numerical models constructed with different geometric dimensions were created with ATENA 3D three-dimensional nonlinear finite element software. In the numerical studies, in addition to the vertical loads in the global sense, the horizontal loads were also taken into account. In our studies, we analyzed the global behavior of the structure, crack propagation, and internal stresses. The results were illustrated on force - displacement diagrams and compared with the results of the laboratory experiments used, thus showing the accuracy and limitations of the numerical modeling procedure. The numerical results were also compared with the results determined on the basis of the equivalent framework models.

Published: October 2023

The main focus of the current paper is the detection of vortices in fluid flow around a circular cylinder and a square cylinder, with an emphasis on the identification of the parameters used for vortex detection. The authors aim to enhance the practicality of an existing vortex detection method (Lagrangian-averaged vorticity deviation) by providing recommendations for the settings of the vortex detection parameters. The simulations were carried out using ANSYS Workbench 2022 R2, encompassing Reynolds numbers between 12 and 140, and angles of incidence from 0° to 45°. The vortex detection was performed using MATLAB R2020b. The paper provides a comprehensive description of the parameters involved in the detection process and their significance, as well as the implementation of the parameter identification. The study results in the determination of the suggested parameter ranges, and a comparative analysis of different vortex detection methods is also presented for the case of the circular cylinder.

Esto puede ser resultado de la interacción entre ambas patologías. El coma mixedematoso puede originarse directa o indirectamente debido a la infección, especialmente en pacientes en cuidados intensivos con síndrome de distrés respiratorio. Por lo tanto, es crucial evaluar la función tiroidea en pacientes con SARS-COV-2, especialmente en casos graves. Conclusión. En pacientes con infección por SARS-COV-2, se debe considerar la evaluación del perfil tiroideo debido a la posibilidad de desarrollar coma mixedematoso. Este diagnóstico debe tenerse en cuenta en casos de alteración de la conciencia con temperatura corporal normal o baja, incluso durante una infección. En estos pacientes, la prevalencia de coma mixedematoso es más alta en mujeres (90% en casos analizados), y la relación entre la frecuencia respiratoria y la saturación de oxígeno no es siempre inversamente proporcional. La hipotensión es común (72.73%) y a menudo está asociada con una disminución en la presión de pulso debido a efectos negativos en la función cardíaca y vasoconstricción.

Introducción. La mendicidad es un problema de carácter social que está vinculado directamente con la desigualdad y la pobreza. Se convierte en un factor de desigualdad social al considerarse que surge en base a la carencia de recursos socioeconómicos dentro de una familia. La situación de mendicidad en los niños, niñas y adolescentes se fundamenta en problemas como: Movilidad humana y la escasa oportunidad laboral. Objetivo. La presente investigación tiene por objetivo identificar los factores sociales que provocan la mendicidad en niños, niñas y adolescentes, en la Fundación Ciudadanos en Acción en la ciudad de Cuenca. Metodología. Para dar respuesta al objetivo se utilizó una metodología cuantitativa de tipo descriptiva siendo su diseño no experimental. Resultados. Los resultados obtenidos determinan que los factores sociales, especialmente, la escasa oportunidad laboral, repercuten de forma significativa en la estructura familiar generando de esa manera actividades de mendicidad. Conclusión.  Las conclusiones indican que tanto la movilidad humana como las oportunidades de empleo constituyen causas de mendicidad infantil, puesto que los niños, niñas y adolescentes sienten la necesidad de apoyar a sus familias utilizando este medio para obtener dinero y alimentos. Por todo esto se recomienda el desarrollo de estrategias integras que promuevan el empleo digno, el acceso a la educación y la protección social, brindando a los NN/A y a sus progenitores una oportunidad para un futuro más seguro y próspero.

Published: October 2023

Introduction: The nightmare of Covid -19 is still not over, due to its antigenic diversity. Covid produces a hypercoagulable state and results in thrombosis which is one of the leading causes of death of Covid 19 patients. Low molecular weight heparin (LMWH)- enoxaparin has proven the benefit of reducing morbidity and mortality by reducing the thrombotic effect. But unfortunately, this anticoagulant can result haematuria and unnecessary hemorrhagic manifestation that may require immediate intervention. The exact scenario of enoxaparin-induced hematuria in the covid patient is still not explored by standard high-volume study.
Objective: Determine the incidence of hematuria by enoxaparin (LMWH) in covid-19 patients.
Material and method: The study was conducted over 210 cases for 6 months duration. Indoor patients receiving subcutaneous enoxaparin who tested positive for Covid19-RTPCR or who had signs of Covid in chest CT (Computerized Tomography) were enrolled. Both microscopic and gross haematuria cases were included in the current study.
Result: Out of 210 patients, only 5 patients (2.38%) developed haematuria. 2 had only microscopic and 3 had gross haematuria. Out of them, 3(60%) were male and 2(40%) were female. Hematuria was more common in those who received a higher dosage of enoxaparin.
Conclusion: This study found that enoxaparin-induced haematuria in the covid patient is not uncommon, and hematuria is significantly higher in patients receiving higher doses. Further high-volume study is recommended on this issue.

Objective: Laparoscopic ureterolithotomy provides results equivalent to open ureterolithotomy for proximal ureteric stones, can be performed transperitoneally and retroperitoneally. The study aims to assess the efficacy of retroperitoneoscopic ureterolithotomy for managing proximal ureteral stones.
Patients and Methods: It was a retrospective study carried out in the period from March 2018 to November 2021. 14 patients with proximal ureteric stones 16–26 mm (20.07± 02.8), all located above the upper border of the sacroiliac joint. Eleven (78.57%) patients underwent retroperitoneoscopy as a primary procedure, one (07.14%) had a history of failed ESWL, and two patients (14.28%) failed retrograde ureteroscopy. Retroperitoneoscopic ureterolithotomy was performed by lumbar approach with initial access conducted by open technique and creation of space by digital and homemade balloon dissection and secured 10 mm Hasson trocar at the primary port site, and 0° telescope advanced. Two 5-mm trocars were placed under visualization forming a triangle. The stone was removed from the primary port site while visualizing retrieval through the 5 mm. port using a fine 30° Cystoscope. Ureterotomy closure was performed by intracorporeal interrupted sutures of 4-0 polyglactin over 5 fr double-J stent, and a drain was left in the retroperitoneum.
Results: Retroperitoneoscopic ureterolithotomy was accomplished in 11 out of 14 cases (78.58%). Three (21.42%) were converted to open surgery (2) and transperitoneal ureterolithotomy (1). The reason for open conversion was the failure to locate the ureter due to severe adhesion in 1 case, technical problems during dissection in 1 case, and another access problem, injury to the peritoneum, which was converted to the transperitoneal route. In 11 successful cases, the mean operative time was 126.5 ± 23.81 (90-170) min. There was no requirement for transfusions. There were no major perioperative and post-operative complications were observed. According to the modified Clavien classification, 07(63.63%) patients were reported to be grade I, whereas 04(36.36%) patients were reported to be grade II. One patient was managed with a course of antibiotics due to post-operative fever. Two patients who developed subcutaneous emphysema and superficial wound infection were treated conservatively. One urinary leakage was subsided by urethral re-catheterization. The drain was removed at 03.81 ±01.25(03-07) days. The mean hospital stay was 04.09 ± 01.13 (03-07) days.
Conclusion: Retroperitoneoscopic ureterolithotomy has acceptable overall complication rates. It is an effective, low-morbidity alternative for the treatment of proximal ureter stones.
