Published: July 2019

Objectives. Cryogenic surgical instruments have been successfully used to conduct tumor ablation. For a long time, cryoablation procedures in Russia were carried out using cryodestructors cooled with liquid nitrogen, which are able to remove heat from the ablation object with high heat flux density and quickly form a cryoablation zone, while being relatively cheap and easy to operate. However, these instruments turned out to be unsuitable for minimally invasive surgeries; therefore, they are squeezed out of practical medicine and cryosurgical instruments are cooled by throttling argon gas. This led to the purpose of the study - the choice of equipment for the organization of local supercooling of pathological tissue.

Method. To solve the problem of optimizing the cryogenic pipeline, a method was chosen for finding the Pareto-optimal solution. To solve this problem, it is sufficient to increase the pressure in the fluid flow directed to the NCS using a liquid micropump. In the role of quality criteria in this task, we selected: hydraulic loss power and heat loss power.

Result. The following results were obtained: the minimum pressure in the vessel, which ensures the movement of the fluid in a single-phase state, according to the magi-line of 1 m length is 0.75 MPa; With this pressure, through a line with a diameter of 1 mm, the flow rate is maintained up to 6 kg / h; heat dissipation ability of the instrument reaches 608 watts. The thermal load on the cooling system of the heatdissipating device of the device for CA is unsteady and is formed due to the heat reserve accumulated in the patient's tissues.

Conclusion. The use of liquid nitrogen in the undersized cryosurgical equipment makes it possible to overcome the noted drawbacks of liquid cryodestructors.

Relevance. Surgical decompression and decompression with stabilization are highly effective for treatment of spinal canal stenosis at the level of lumbar spine. However, complications developing after application of rigid fixation systems resulted in active introduction of dynamic implants into clinical practice.Purpose of the study — to compare effectiveness of nitinol and titanium nails for lumbosacral fixation in surgical treatment of degenerative spine diseases.Materials and methods. 220 patients who underwent surgeries in 4 hospitals were randomized into two groups, each consisting of 110 patients (1:1 ratio): a group of patients who underwent stabilization of the vertebral motor segments with rods of nitinol with the required volume of decompression at the operation level and a group of patients who underwent stabilization of the vertebral motor segments with standard rods of titanium with the required volume of decompression at the intervention level. Patients suffered clinically significant spinal canal stenosis in one or two adjacent segments: from L3 to S1. Outcomes were evaluated during three years postoperatively by VAS scale for spine and lower limbs, and by ODI and SF-36 scales.Results. All scales demonstrated better values in both groups of patients, namely, significant decrease of pain syndrome and improvement in mental and physical health. X-ray examination of all patients during the study period demonstrated restoration of lumbar lordosis. Group of patients with dynamic nails featured less complications rate related to metal implants including adjacent segment disease.Conclusion. Transpedicular fixation of lumbosacral spine by nitinol nails is an effective technique allowing to preserve motion along with stable fixation.
Foot Function Disorders in Children with Severe Spondylolisthesis of L5 Vertebra
Authors: Nikityuk I. E. , Vissarionov S. V.
Published: July 2019

Background. In children with spondylolisthesis, there are still unexplained aspects in the relationship of the degree of displacement of the L5 vertebra with the severity of the clinical picture and neurological disorders. At the same time, aspects of the mutual aggravating influence of the indicated spinal disorder on the condition of the feet have not been studied. Therefore, the problem of identifying disorder of foot function in children with spinal spondylolisthesis of the L5 vertebra is relevant.Aim of the study — to evaluate the deviations in parameters of the transverse and longitudinal arches of feet in children suffering from severe spondylolisthesis of the L5 vertebra.Materials and Methods. In the period from 2016 to 2018, 12 children aged 14.1 y.o. [12,7; 15,5] were examined with spondylolisthesis of the L5 vertebral body of grade III-IV, accompanied by stenosis of the spinal canal at the same level and by compression of the roots of the spinal cord. Imaging diagnostics included multispiral computed tomography (MSCT) and magnetic resonance imaging (MRI). To estimate the function of the feet, double-bearing and single-bearing plantography was used. The data for the control group included only plantographic examinations of 12 healthy children of the same age.Results. In patients with spondylolisthesis, the mean value of the anterior t and intermediate s plantographic bearing indices were significantly lower than those of healthy children. At the same time, in tests with an increased load on the foot in patients, there was no significant increase in the mean anterior t and medial m indices, which indicates the dynamic rigidity of the transverse and medial longitudinal arches. The value of the lateral plantographic index l showed its significant pathological increase compared with the normal value at double-bearing load, which indicates the static rigidity of the lateral longitudinal arch. Correlation analysis demonstrated that, against the normal state, the bearing ability of the feet in sick children is realized through a pathological strengthening of the functional relationship between the arches of the foot at double-bearing load and a non-physiological reduction of the interaction between arches at single-bearing load.Conclusion. In children with severe forms of vertebra spondylolisthesis, the parameters of plantographic characteristics indicate the rigidity of the arches of the feet and the distortion of their bearing pattern. It is necessary to take into account the aggravating effect of rigid feet on the state of the spine and include the examination of the bearing function of the feet in the algorithm for the comprehensive diagnosis of children with spondylolisthesis.

BACKGROUND

Cross-border malaria is a significant obstacle to achieving malaria control and elimination worldwide.

OBJECTIVE

This study aimed to build a cross-border surveillance system that can make comparable and qualified data available to all parties involved in malaria control between French Guiana and Brazil.

METHODS

Data reconciliation rules based on expert knowledge were defined and applied to the heterogeneous data provided by the existing malaria surveillance systems of both countries. Visualization dashboards were designed to facilitate progressive data exploration, analysis, and interpretation. Dedicated advanced open source and robust software solutions were chosen to facilitate solution sharing and reuse.

RESULTS

A database gathering the harmonized data on cross-border malaria epidemiology is updated monthly with new individual malaria cases from both countries. Online dashboards permit a progressive and user-friendly visualization of raw data and epidemiological indicators, in the form of time series, maps, and data quality indexes. The monitoring system was shown to be able to identify changes in time series that are related to control actions, as well as differentiated changes according to space and to population subgroups.

CONCLUSIONS

This cross-border monitoring tool could help produce new scientific evidence on cross-border malaria dynamics, implementing cross-border cooperation for malaria control and elimination, and can be quickly adapted to other cross-border contexts.

Authors: Orozco Bolaños Hermila , Hernández Vázquez Maricela , García Juárez Guillermina , Suárez González Gerardo
Published: July 2019

La actividad agrícola en el estado de Tlaxcala depende en gran medida del clima. El productor de maíz se encuentra inmerso en esta contingencia: lo percibe de forma positiva o negativa dependiendo de los sucesos que se presenten. El objetivo fue determinar la percepción y caracterizar los saberes que tienen acerca del clima, el impacto del cambio climático en la producción y la capacidad adaptativa del maíz. La investigación fue de tipo descriptivo-analítico. La población de estudio fueron productores de maíz criollo bajo condiciones de temporal. Se tomó una muestra no probabilística de tipo incidental. La técnica fue la encuesta: se aplicaron 1930 cuestionarios en 39 municipios del estado de Tlaxcala. Los principales hallazgos fueron que 78 % de los productores son mayores de 50 años de edad y 60 % cuenta con educación primaria. La sequía y las heladas son los principales eventos del clima que han impactado al cultivo y han ocasionado pérdidas y bajos rendimientos. Las estrategias que han adoptado ante las variaciones del clima son el cambio en las fechas de siembra, selección de semilla nativa resistente a la sequía y uso de abonos orgánicos para minimizar los efectos del clima. La percepción de los entrevistados estuvo significativamente correlacionada (p ≥ 0.05). Los conocimientos y saberes del clima y la semilla que posee el agricultor están en peligro, por lo tanto, la seguridad alimentaria se ve amenazada por los efectos del cambio climático en la producción de maíz de temporal.
REJECTION PENGGUNAAN ATBM DAN ATBMTT DALAM PEMBUATAN SONGKET PANDAI SIKEK
Authors: Saputra Hanafi
Published: July 2019

Abstrak

Pandai Sikek merupakan sentral produksi songket terkemuka di Sumatera Barat. Songket Pandai Sikek yang tergolong berkualitas tinggi tersebut dibuat menggunakan alat tenun tradisional yang dikenal dengan panta. Meskipun bisa menghasilkan songket yang berkualitas, namun panta memiliki keterbatasan-keterbatasan, antara lain: proses bertenun yang membutuhkan waktu lama, tingginya resiko kesalahan, dan sebagainya. Dihadapkan pada keterbatasan itu, Pemerintah Pusat melalui Departemen Perindustrian RI memperkenalkan alat tenun baru, yaitu ATBM, serta ATBMTT yang merupakan produk beberapa pengrajin (penenun) setempat. Hanya saja kedua peralatan baru itu (ATBM & ATBMTT) ditolak kehadirannya oleh penenun setempat, buktinya lebih dari 98% penenun tetap menggunakan panta.Hasil penelitian menunjukan, bahwa penenun menolak (rejection) ATBM dan ATBMTT sebagai pengganti panta adalah sebagai berikut: (1) keterbatasan informasi tentang esensi ATBM & ATBMTT sebagai alat inovasi; (2) tingginya kerumitan dan keterbatasan alat inovasi; (3) rendahnya kualitas produk ATBM dibandingkan produk panta sehingga harga jual produk rendah; (4) khusus ATBMTT, adanya hambatan agen pembaru (keengganannya untuk menyebarkan ATBMTT kepada penenun lain); dan, (5) adanya nilai sistem yang tertanam dalam diri adopter (penenun). Nilai sistem tersebut yaitu pemahaman tentang menenun merupakan keterampilan sakral dan identitas serta jati diri sebagai orang Pandai Sikek.

Pengembangan desa wisata membutuhkan partisipasi masyarakat lokal dalam keseluruhan tahap pengembangan mulai tahap perencanaan, implementasi, dan pengawasan. Akan tetapi, dalam realitas sering terjadi pengabaian partisipasi masyarakat. Penelitian ini bertujuan mengkaji keterlibatan masyarakat lokal dalam pengembangan desa wisata dan merumuskan model pengembangan desa wisata yang mengedepankan partisipasi masyarakat lokal. Penelitian dalam tulisan ini dilakukan di desa wisata Teluk Bakau, Kecamatan Gunung Kijang, Kabupaten Bintan. Pengumpulan data dilakukan dengan cara observasi, wawancara mendalam, dan studi literatur. Metode analisis yang digunakan adalah analisis deskriptif kualitatif. Tulisan ini menunjukkan bahwa pengembangan desa wisata di Desa Teluk Bakau belum melibatkan masyarakat lokal. Peranan pemerintah terlihat dominan, padahal bila mengacu pada pendekatan tata kelola pemerintah yang bersih dan berkelanjutan peran pemerintah diharapkan menjadi fasilitator dengan memberikan peran dan manfaat yang lebih besar kepada masyarakat lokal. Diperlukan kemauan politik pemerintah untuk mengurangi perannya dalam pengembangan desa wisata dengan membuka ruang bagi masyarakat untuk berpartisipasi.

Sheath rot disease caused by Sarocladium oryzae is an important disease on rice. The pathogen that infects uppermost leaf sheath enclosing to the young panicles can cause yield losses up to 85%. Though the disease is commonly controlled using synthetic fungicides, the use of natural products that safer to the environment have been enormously explored. The research aimed to test growth inhibition of S. oryzae colony using methanol leaf extract of binahong (Anredera cordifolia). The research was carried out from June until December 2017 at the Laboratory of Biotechnology Plant Protection, Department of Plant Pest and Diseases, Faculty of Agriculture, Universitas Padjadjaran. The method used was Randomized Complete Design consisted of six treatments and four replications. The treatments were five concentrations of binahong leaf extract of 0.125%, 0.25%, 0.5%, 1%, 2% and one control treatment. The result showed that binahong leaf extract did not inhibit the growth of S. oryzae. The highest inhibition percentage of 4.55% at 0.25% concentration was considered to be a low inhibition category. Although the colony growth of S. oryzae was not significantly inhibited, the extract caused hyphal abnormalities. This actually shows the antifungal potency of the binahong leaf extract that needed further examination with more adequate methods.Keywords : Anredera cordifolia, botanical pesticide, rice sheath rot

Pulau Weh merupakan pulau vulkanik yang dilalui jalur sesar aktif the Great Sumatran Fault. Keberadaan jalur sesar aktif pada suatu kawasan berimplikasi pada ancaman bahaya gempa bumi. Kami telah menggunakan data Digital Elevation Model (DEM) dari Shuttle Radar Topography Mission (SRTM) untuk pemetaan jalur-jalur sesar di Pulau Weh. Data DEM yang diproduksi oleh SRTM diekstrak menjadi hillshade dengan memberikan variasi sudut penyinaran matahari dan altitude 45o. Analisis topografi permukaan bumi memberikan penampakan gerusan-gerusan sesar dan rekahan. Selanjutnya kelurusan-kelurusan ditarik secara manual berdasarkan analisis sesar dan rekahan untuk tiap perbedaan sudut elevasi matahari pada hillshade. Kelurusan-kelurusan yang diperoleh dari tiap hillshade kemudian di-overlay. Berdasarkan jenisnya, kelurusan yang dianggap sebagai sesar dan rekahan diinterpretasi dengan memberikan grid 500 x 500 m. Dengan menggunakan metode FFD, didapatkan kelurusan-kelurusan yang berasosiasi dengan struktur atau merupakan refleksi gambaran topografi berupa kelurusan sungai, kelurusan lembah, struktur sesar maupun rekahan, kontak batuan dan kemunculan manifestasi panas bumi. Terdapat empat lokasi yang memiliki nilai anomali densitas kelurusan tinggi. Dominasi kelurusan yang terdapat di Pulau Weh yaitu Barat Laut-Tenggara. Arah dominan ini bersesuaian dengan arah Sesar Sumatera. Weh Island is a volcanic island crossed by the Great Sumatran Fault. Presence of such active fault may trigger seismic hazard on the island. We have applied Digital Elevation Model (DEM) from Shuttle Radar Topography Mission (SRTM) data to delineate fault distribution in Weh Island. The DEM data produced by SRTM were extracted as hillshade using variation of sun irradiation angels and altitude 45 o. Surface topographic analysis provided fractures and faults signatures on the study area. The faults and fractures lineament were drawn manually for each angle on the hillshades. The lineaments for each hillshade were overlaid. Using Fault Fracture Density (FFD) method we found lineaments associated as geological structures reflected from rivers, valleys, faults, fractures, rock contacts, and geothermal manifestations. There are four locations with high density lineaments on the island. The lineaments mostly directed in Northwest-Southeast which is same direction as the Great Sumatran Fault. Keywords: DEM, SRTM, geomorphology, the Great Sumatran Fault.

Telah dilakukan pemodelan 2D data Magnetotellurik (MT) di Gunung Api Seulawah Agam. Penelitian ini bertujuan untuk mendapatkan model konseptual lapangan panas bumi Gunung Api Seulawah Agam berdasarkan model resistivitas 2D. Data fungsi transfer MT yang digunakan yaitu dari rentang frekuensi 2,34 - 320 Hz yang terdiri dari 7 titik stasiun pengukuran. Data titik pengukuran terdiri dari nilai intensitas medan listrik dan intensitas medan magnet yang memiliki 28 frekuensi. Total panjang lintasan pengukuran yaitu sepanjang 27,7 km. Lintasan pengukuran memotong Gunung Api Seulawah Agam dari arah Selatan ke Utara. Data hasil pengukuran yaitu berupa nilai resistivitas semu dan fase yang kemudian dimodelkan menggunakan kode REBOCC. Terdapat 3 model yang dihasilkan dari proses inversi data MT menggunakan REBOCC yaitu mode TE, mode TM dan mode TE+TM. Model mode TE+TM merupakan model yang paling bagus karena menghasilkan model yang lebih jelas dan smooth bila dibandingkan dengan model pada mode TE dan mode TM. Hasil model konseptual menunjukkan bahwa pada lapisan pertama yaitu lapisan top soil (lapisan teratas) memiliki nilai resistivitas sebesar 20 - 60 Ω.m, yang terdapat pada jarak 6 - 23 km. Lapisan kedua yaitu lapisan clay/caprock dengan nilai resistivitas relatif rendah yaitu lebih kecil dari 10 Ω.m, yang berada pada jarak 6 - 27,7 km. Lapisan clay/caprock memiliki sifat impermeabel dan konduktif. Selanjutnya lapisan ketiga yaitu lapisan reservoir dengan nilai resistivitas berkisar antara 10 - 100 Ω.m. 2D modeling of magnetotelluric data has been conducted at Seulawah Agam volcano. This study aims to obtain a conceptual model of Seulawah Agam geothermal field based on 2D resistivity model. The magnetotelluric data were measured in range of frequency from 2.34 to 320 Hz at 7 stations along a profile crossing the Seulawah Agam volcano. The length of the profile is 27.7 km with a direction from north to south. The apparent resistivity and phase of magnetotelluric transfers function were used for the 2D inversion modelling of REBOCC code. The inversion was carried out using TE-mode, TM-mode and TE+TM-mode to obtain a better model. The model inverted of TE+TM-mode has resolved well, resistivity variation of subsurface of the Seulawah Agam volcano area. The inverted model shows the top later has resistivity values from 20-60 Ω.m, which is interpreted as a top soil. The second layer is a layer of clay/caprock with a relatively low resistivity values of less than 10 Ω.m. The third layer is predicted as reservoir with resistivity values ranging between 10-100 Ω.m. Keywords: magnetotelluric method, resistivity, 2D model, REBOCC code and Volcano Seulawah Agam.

Published: July 2019

The article presents an initial Russian experience of video-thoracoscopic bronchoplastic lobectomies performed in 2 clinical cases of centric lung tumors. The upper bronchoplastic lobectomies with right lymphodissection were carried out on two patients in 2012. Complications weren’t observed in intraoperative and postoperative periods. There wasn’t relapse during two years after operation. Thus, the authors came to conclusion that thoracoscopic bronchoplastic lobectomies turned out to be safe and effective interventions in individual patients with centric tumor location, which wasn’t extended outside mouth of the lobar bronchus. The choice of candidates for thoracoscopic bronchoplasty was made using video-bronchoscopy, angio-computer tomography of the thorax and PET. This allowed avoiding an invasive staging and excluded patients with substantial extra-bronchial lesions.

All the patients had abdominal aortic aneurisms with the diameters from 41 to 84 mm against the background of severe somatic pathology. It was a contraindication to planned open surgery. An installation of stent-graft was successful in all 72 follow-ups. It wasn’t necessary to use a conversion to open surgery. The follow-up period consisted of 44,6±2,1 months. Control ultrasound and computer tomography studies hadn’t revealed an increase of aneurism sack sizes or «leakages». A reduction of abdominal aortic aneurism sizes was noted in 37 patients on 4-5% during first year after operation. The stentgraft implantation extends the possibilities of abdominal aortic aneurism treatment for patients from a high surgical risk group.

The article is based on the treatment results of 44 patients with follicular tumor of thyroid gland. A staged morphological assessment of thyroid nodes was performed for all patients: in case of preoperative fine-needle biopsy, urgent intraoperative study and according to results of final histological research. The urgent histological study of surgical material was conducted for 44 patients with diagnosis «follicular tumor» according to fine-needle biopsy. The data of final histological study were matched with findings of intraoperative research. A micro-follicular adenoma was detected in 22 patients (50%) and 6 (13,6%) patients had this diagnosis combined with autoimmune thyroiditis. The general part of patients didn’t changed in final study, but the rate of diagnosis «micro-follicular adenoma against the background of autoimmune thyroiditis» increased. Papillary carcinoma was revealed in 5 (11,4%) patients and follicular cancer had 4 (9,1%) patients detected in intraoperative study and 3 (6,8%) more patients according to data of final research. The histopathologic feature of colloid goiter was observed in 7 (15,9%) cases and a part of such patients reduced to 6,8% during final study. One of the patients (2,3%) had final diagnosis «oncocytoma». In case of thyroid nodules detection the needle biopsy should be carried out regardless to the size of nodule. The authors recommended performing the surgery with the urgent histological study in case of undetermined histological report. The following surgical strate gy was specified by the results of the urgent histological report.

An analysis of the results of complex examination and treatment of 181 patients with varicose vein disease (according to CEAP classification C3-C6) was made. Patients were divided into 2 groups. The first group included 106 (58,6%) patients with venous clinical severity score C3 and the second group - 75 (41,4%) patients with score C4-C6. An ultrasonic scintiangiography was used to determine the localization, intensity and length of blow-out in venous system of affected limb. The study found out 2 mechanisms of development of incompetent perforating veins. A superficial blood reflux influenced on the progress of venous insufficiency in 41 (38,7%) patients of the first group. The superficial and deep blood refluxes facilitated to development of the disease and were detected in 67 (89,4%) patients of the second group. It was stated, that there is a direct relation of perforating blood reflux rate with the level of intensity of superficial and deep blood reflux. The more expression of the refluxes took place, the more cases of incompetent perforating veins.

The article studied an influence of operative treatment on miners in the stage of burn shock, complicated by multi- and combined trauma and how these treatment options have changed the lethality and burn complications rates. All data based on an analysis of retrospective research. A primary surgical treatment of burn wounds was performed using simultaneous grafting by temporary biological cover for superficial burns during the burn shock stage in the main group of patients. For miners of comparison group this strategy hasn’t been applied and they were operated after ending of burn shock. The rate of development of burn sepsis decreased in 3,2 times (p=0,0001), the frequency of pneumonia reduced in 2,91 times (p=0,0001) and toxic encephalopathy - in 1,7 times (p=0,004) in the main group in relation to the comparison group. The authors made a conclusion, that significant reduction of the rate of the most dangerous complications of burns allowed decrease of lethality in patients of main group in 2,6 times in relation to the comparison group. There wasn’t carried out the primary surgical treatment of burns with covering of postoperative wound surfaces by temporary biological material during burn shock stage in comparison group.

Standard methods of diagnostics haven’t got a proper sensitivity and specificity concerning assessment of regional nodal involvement in case of rectal cancer. Therefore it is necessary to look for new method of diagnostics, detect risk factors and unfavorable prognosis in relation to lateral lymph node metastasis. At the same time, there should be a differentiated approach to the choice of therapeutic management in rectal cancer. Investigation of variability of blood supply of the rectum could be an additional method of diagnostics in rectal cancer.

Published: July 2019

An introduction of blocking osteosynthesis was recently included into practice of treatment of forearm fractures. The forearm has a very difficult biomechanics and extremely important functional value. There are really high requirements to accuracy of reposition and stability of forearm fracture fixation. The blocking osteosynthesis successfully combines fixation stability with functionality, although its performance technique isn’t so simple, that forces experts to use other methods of fixation. It is possible successfully use advantages of the method by studying and keeping variety of operation nuances of blocking osteosynthesis on forearm in order to restore anatomy, biomechanics and obtain the stable fixation. The period of rehabilitation could be combined with period of union of bones in this case without postoperative complications such as nonunion of bones, construction fractures and instability of osteosynthesis. The method would be optimal provided that a surgeon masters the technique of construction implantation. There are maximum advantages in treatment of complicated fractures (nonunion of bones, false joint and defects) due to functionality of the method.

A treatment of fractures of distal metadiaphysis of the humeral bone remains an actual problem of modern traumatology at present time. This is associated with immediate proximity of the radial nerve and risk of iatrogenic injury in external fixation, presence of short distal fragment, comminuted nature of fracture, complexity of treatment method selection, need of extensible approach. Biomechanical features of different fixators were analyzed in consideration of presence of short distal fragment, traumatic of external fixation and risk of iatrogenic injury of the nerve. The authors suggested the method of osteosynthesis of the humerus by using blocking osteosynthesis with preliminary extension of intra-medullary canal of distal fragment for obtaining stable osteosynthesis (priority № 2014105323 from 14.02.2014). The proposed method allowed avoiding the iatrogenic neuropathy of the radial nerve, providing the stability of fixation higher, than in case of external fixation. It excludes the need of external immobilization and combines the period of bony union with the period of rehabilitation and socially integrates the patient in minimal terms.

Prostate biopsy guided by transrectal ultrasonography (TRUS) is largely used in prostate cancer diagnostics. This procedure is usually quite painful and fear of pain could scare patients from this important research. The aim of the study was to compare methods of anesthesia for prostate biopsy. The patients were divided into 4 groups (40 patients in each group). TRUS-guided periprostatic anesthesia with 1% solution of lidocaine (10 ml) was carried out in the first group. An intrarectal introduction of 5 g EMLA cream (lidocaine 2,5% and prilocaine 2,5%) was applied in the second group. The intrarectal introduction of 10% lidocaine spray (3 doses) was used in the third group. Placebo as ultrasonic gel was utilized for the fourth group. The authors used the 100- score linear visual analog scale (LVS 1-100) and 5-score numeric visual scale (NVS-4). Minimal scores of pain were obtained in patients using TRUS-guided periprostatic anesthesia with 1% solution of lidocaine (10 ml). This type of anesthesia didn’t lead to increase of the number of complications.
