Litiasis renal bilateral y catéter doble J calcificado grado V: acceso percutáneo en posición supina. A propósito de un caso
Authors: Camacho Castro Alberto Jorge 
Published: February 2022

ANTECEDENTES: Debido al progreso en el equipo y las técnicas quirúrgicas de endourología en las pasadas dos décadas, la mayor parte de las cirugías por litiasis se han efectuado mediante accesos de mínima invasión, incluso se han ampliado las opciones de tratamiento de las complicaciones derivadas del uso de material externo, como los catéteres doble J. CASO CLÍNICO: Paciente femenina de 35 años, con dolor tipo cólico en la fosa renal izquierda, con irradiación al flanco ipsilateral, fiebre no cuantificada, disuria y hematuria. En la exploración se encontró litiasis renal bilateral con hidronefrosis izquierda y se colocó un catéter doble J izquierdo. Un año después, el catéter se calcificó en su totalidad. Se realizó nefrolitotomía percutánea bilateral, litotripsia de la J distal y extracción del catéter calcificado grado V. La evolución de la paciente transcurrió sin complicaciones. Ambas sondas de nefrostomía se retiraron a los 7 días posteriores del procedimiento y el catéter doble J izquierdo 15 días después. La tomografía de control confirmó la tasa libre de litiasis. Actualmente se encuentra asintomática y con adecuada mecánica miccional. CONCLUSIONES La nefrolitotomía percutánea en posición supina ofrece ventajas importantes para el paciente y el cirujano. El acceso y la decisión de la posición en que se practicará la punción renal debe individualizarse en cada caso. PALABRAS CLAVE: Nefrolitotomía percutánea; catéter doble J calcificado; posición de Valdivia.
Ultrasonido Doppler de pene en la evaluación posterior a prostatectomía radical. Revisión bibliográfica y recomendaciones
Authors: Uribe Juan Fernando , Aluma Luis Javier 
Published: February 2022

Changes in sexual function are common in patients following radical prostatectomy for prostate cancer. Sexual rehabilitation after radical prostatectomy requires a complex process in which the diagnosis is refined, and an accurate treatment program is chosen. Penile Doppler ultrasound is a commonly used method for diagnosing erectile dysfunction and it is very useful in certain cases after surgery to improve the assessment of arterial evaluation, venous leaks, and quality of the cavernous tissue and fascia. A literature search was conducted using the databases from Google and PubMed to identify original and review articles that examined the uses of penile Doppler ultrasound in post-radical prostatectomy evaluation or post-surgery rehabilitation. Search terms included: Erectile dysfunction post radical prostatectomy, sexual function post radical prostatectomy, Penile evaluation post-prostatectomy, Diagnosis of erectile function after radical surgery, Penile Doppler ultrasound AND prostatectomy, Penile Doppler ultrasound AND sexual rehabilitation. The initial search resulted in 415 articles. After applying additional filters, 46 studies were included in the present review. Backgrounds of the most relevant guidelines were cited: Standard practice in sexual medicine, Standard operating procedure in sexual medicine, International Consultation on Sexual Medicine, and the EAU and AUA guidelines. Information on the use of penile Doppler ultrasound before surgery is extremely inconsistent in the literature. The recommendations for a successful evaluation of post-radical prostatectomy patients were included. Sexual rehabilitation after radical prostatectomy requires a complex process. There is great inconsistency in the literature with respect to the definition of what is considered normal erectile function before surgery and what may be considered normal erection after radical prostatectomy. The cost of penile Doppler ultrasound is a modest component of the penile post-radical prostatectomy rehabilitation process. Current evidence does not support the systematic use of penile Doppler ultrasound, but it must be included in the management algorithm of the patient undergoing radical prostate surgery so that erectile function can be properly evaluated.

Metástasis atipicas del tumor renal
Authors: Hernández Alcaraz David , Beneto-Alducin Begoña , Morales-Jiménez Pedro 
Published: February 2022

Introducción: El objetivo del presente trabajo es presentar tres casos clínicos con presentaciones poco frecuentes de metástasis de carcinoma renal.
Descripción de los casos: El primer caso es una mujer en la que se objetivan metástasis en el tiroides tras una tiroidectomía. El resto del estudio de extensión era negativo y no necesitó de tratamiento adyuvante. El segundo caso es el de una mujer que acudió a urgencias por retención urinaria secundaria a una metástasis uretral de un carcinoma renal, sin metástasis a otros niveles. El tercer caso es de un varón con una recidiva de un carcinoma renal de tipo papilar en la mucosa vesical, asociado a metástasis pulmonares.
Discusión: El 34% de las metástasis en tiroides son de origen renal. La uretra es un sitio poco frecuente de metástasis. En líneas generales, las metástasis renales en vejiga indican mal pronóstico, únicamente existen 56 casos descritos en la literatura. El tratamiento de elección ante lesiones resecables es la extirpación quirúrgica, reservando la terapia antiangiogénica para las que no lo son.
Conclusiones: Las metástasis tiroideas, vesicales y en uretra son sitios poco frecuentes de metástasis de cáncer renal. Suelen indicar fases avanzadas de la enfermedad y su tratamiento, si son resecables, consiste en su extirpación quirúrgica.

Authors: Ríos-Burgueño Efrén Rafael , Verdugo-Nieto Lucía , Velarde-Rodríguez Ismael , Velarde-Félix Jesús Salvador 
Published: February 2022

Antecedentes. Las metástasis de carcinoma de células renales a páncreas y posteriormente a hígado son infrecuentes y a veces asintomáticas, por tal motivo el tiempo entre la nefrectomía y su detección puede demorar.
Caso clínico. Mujer de 76 años con tumor en páncreas e hígado, con antecedente de nefrectomía derecha por carcinoma de células renales realizada hace 26 años, motivo por el cual se sometió a pancreatectomía distal y tratamiento con pazopanib, respectivamente. El nódulo pancreático dio positividad a citoqueratina 8, 18 y cd10, mientras que el resultado de estudio de la biopsia hepática fue neoplasia epitelial maligna. Ambos consistentes con metástasis de carcinoma renal de células claras.
Discusión. Actualmente la paciente se encuentra asintomática, en seguimiento y vigilancia. Por la naturaleza biológica del carcinoma de células renales, sus metástasis deben buscarse intencionadamente para detectarlas en etapa temprana y ofrecer un tratamiento oportuno.
Efecto de la electroestimulación del nervio tibial en la musculatura del piso pélvico de pacientes con síndrome de vejiga hiperactiva
Authors: Pérez Martínez Carlos , Palacios-Galicia José Luis , Vargas-Díaz Irma Beatriz , Cruz-Gómez Yolanda , García-Sánchez Daniel 
Published: February 2022

Antecedentes y Objetivos: El Síndrome de Vejiga Hiperactiva (svh) presenta alteraciones motoras como hipertonía de la musculatura del piso pélvico (mpp). El objeto del estudio es demostrar las características de la electromiografía de superficie (emgs) del mpp en el svh tratados con electro-estimulación percutánea del nervio tibial (ptns).
Material y Método: Estudio prospectivo, observacional, controlado. Se realizó emgs de mpp a 17 voluntarios con svh rebelde a tratamiento, antes, durante la ptns y 72 horas después. Se asignaron 2 grupos: Catorce voluntarios del grupo ptns, y 3 voluntarios del grupo placebo. Se incluyeron pacientes con evolución mínima de 6 meses, frecuencia urinaria de 8 o más, sin toma de medicamentos. Se excluyeron pacientes con urocultivo/espermocultivo positivos, litiasis, biopsia y/o cirugía de órganos pélvicos ó cáncer pélvico, y lesiones del snc. Las variables se analizaron mediante Anova y Tukey pos hoc test, 95% ic, usando el software spss 10.1.
Resultados: Media de edad 34.23±12.90 años, media del tiempo de evolución 19.58±12.08 meses, sin diferencia estadística en entre grupos. La diferencia de las medias en el promedio de emg (avgemg) del grupo ptns pre vs trans de 0.125 µV y de pre vs 72 horas de 0.171 µV fueron significativas (p<0.05), mientras que en el grupo placebo la diferencia de las medias avgemg de 0.013 µV y 0.006 µV sin diferencia estadística (p>0.05).
Conclusiones: El cambio inmediato sobre la mpp que permanece hasta 72 horas después de la ptns, es un posible mecanismo de acción de neuroplasticidad de la neuromodulación del nervio tibial.

Published: February 2022

Antecedentes: Actualmente el 70% de los pacientes operados de ureteroscopia reciben colocación de catéter doble j debido a que se cree que disminuye la obstrucción secundaria a edema ureteral o a fragmentos de lito, pero la colocación no es inocua, ya que conlleva una gran variedad de efectos secundarios como frecuencia, urgencia, hematuria, disuria y tenesmo, así como un impacto económico. Nuestro objetivo es evaluar el manejo actual del catéter doble j en pacientes posoperados de ureteroscopia y los síntomas posquirúrgicos asociados.
Materiales y métodos: Estudio retrospectivo de ureteroscopias realizadas en el Hospital Dr. Manuel Gea González durante el 2017 en pacientes mayores a 18 años. Se analizaron las frecuencias en readmisiones al servicio de urgencias durante la primera semana posoperatoria y los síntomas asociados al uso de catéter doble j, así como complicaciones posoperatorias.
Resultados: Se registraron 105 ureteroscopias. El sexo masculino fue el predominante en hasta 55%; las ureteroscopias semirrígidas fueron las más prevalentes con un 71%. Se colocó preoperatoriamente catéter doble j en 69 pacientes y posoperatoriamente se colocaron en 41 pacientes. Durante el seguimiento los pacientes con colocación de catéter jj refirieron síntomas asociados a la colocación del catéter, lo cual ameritó visita a urgencias, encontrando únicamente asociación significativa para polaquiuria (p=0.001). Se obtuvo un total de 95 pacientes libre de litiasis, de los cuales a 61 (64.2%) se les colocó catéter doble j y 2 quedaron con litiasis residual y sin catéter.
Conclusiones: De los 61 pacientes que se les colocó catéter doble j, 57 (82%) presentaron al menos un síntoma relacionado con el catéter; el 64.2% fueron ureteroscopias no complicadas a las cuales se les colocaron catéter doble j, por lo que creemos necesario realizar un estudio prospectivo y aleatorizado con un mayor número de pacientes para confirmar los resultados previamente reportados y establecer de manera más clara y objetiva las indicaciones para el uso del catéter doble j en nuestro hospital.

Objective
Develop and validate a questionnaire to evaluate the discomfort related to ureteral stent that is simple, hetero-self-administered
Material & Methods
A pilot instrument based on the ussq was designed, subsequently structured using the Delphi method and applied to 72 patients with ureteral stent after semirrigid ureteroscopy. For its validation, we use Cronbach's alpha and Pearson's coefficient.
Results
The udt designed by Likert scale model, with 6 dimensions: 1-urinary symptoms, 2-pain, 3-daily life, 4-sex life, 5-medical care / use of analgesics and 6-quality of life 6, 2, 1, 1, 2, 1 items respectively. The tool defines greater discomfort in the patient as the score increases by dimension and total score; The score increases according to the severity of the symptoms, with a max-score of 61 points. Validation studies made the questionnaire internally consistent (Cronbach 0.820) with good reliability (Pearson 0.850). The correlation of urinary symptoms (r = 0.929, p = 0.00), pain (r = 0.880, p = 0.00), daily life (r = 0.625, p = 0.00), quality of life (r = 0.768, p = 0.00) of both questionnaires was statistically significant. udt application time (m = 1.8min SD = 0.76) vs ussq (m = 8.3min SD = 0.76)
Limitants
Small sample that requires more patients to demonstrate the effectiveness of the questionnaire
Value
This questionnaire represents an easy tool to evaluate in a simply way the ureteral stent discomfort.
Conclusions
The udt is a tool of simple and rapid application, comparable to the USSQ, for the evaluation of symptoms related to the ureteral stent.

Published: February 2022

Clinical case description: A 55-year-old man came to the hospital emergency service after being bitten in the penis by his dog. The accident caused several lesions on the glans penis and circumferential avulsion of the skin from the balanopreputial sulcus to thebase of the penis. The scrotum, testes, corpora cavernosa, and urethra were intact.
Relevance: Genital trauma from an animal bite is a complex lesion, given that it involves a contaminated wound with a high risk of infection and complication because it can compromise the integrity of the urethra and corpora cavernosa of the patient. Due to the rareness of those types of lesions, there are no clinical guidelines establishing their correct management.
Conclusion: More studies with greater scientific evidence are needed to aid in the formulation of standardized clinical practice guidelines, enabling improved functional and cosmetic results in those patients.
Intracavernous application of autologous bone marrow stem cells for medical treatment-refractory erectile dysfunction: A case report
Authors: Robles-Torres José Iván , Mancías-Guerra Consuelo , Garza-Bedolla Alejandra , Gómez-Guerra Lauro Salvador 
Published: February 2022

Clinical case description: A 61-year-old man with severe erectile dysfunction related to diabetes mellitus of long duration was treated through intracavernous stem cell application. Transplantation of autologous bone marrow stem cells through a single intracavernous injection was performed. Clinical response, Doppler ultrasound of the penis, and adverse events were evaluated during the 50-week follow-up. The highest clinical response was reported at week 12, but it diminished thereafter. At the end of follow-up, ultrasound identified the presence of neovascularization emerging from the cavernous arteries.
Relevance: Numerous preclinical trials have demonstrated efficacy and safety, but there is insufficient clinical evidence showing promising results.
Clinical implications: No adverse events were detected, and ultrasound revealed hemodynamic changes that were possibly related to the therapy. The source and dosage of stem cells, as well as subsequent therapeutic applications, pose questions that remain to be answered.
Conclusions: Stem cell therapy for erectile dysfunction is a field of research that has sparked interest in numerous scientific groups, but clinical experience is still limited.
Signo ecográfico del remolino en torsión testicular intermitente, presentación de 2 casos
Authors: Arroyo Carlos , Ávila-Sánchez Pablo Alejandro , Cuan-Baltazar Jose Yu Nam , Soto-Vega Elena 
Published: February 2022

Case description: The two cases were characterized by multiple episodes of very intense pain that resolved spontaneously. Testicular ultrasound was carried out in both cases, during an acute episode of pain. The Whirlpool sign was identified, together with vascular compromise of the testis, suggesting intermittent testicular torsion that required surgical treatment.
Relevance: The aim of our report was to describe how intermittent testicular torsion is an uncommon pathology that should be suspected in young patients presenting with episodes of intense pain. Diagnostic ultrasound should be performed during an episode of pain.
Clinical implications: Due to vascular compromise in the testis, opportune diagnosis is important. It begins with diagnostic suspicion that is supported by the patient’s clinical manifestations and proceeds to early bilateral testicular fixation, preventing necrosis of the testis.
Conclusions: Intermittent testicular torsion is rare and difficult to diagnose. Prompt identification of the whirlpool sign during an acute episode of pain is essential for making the diagnosis and preventing the loss of the testis, which could result from underestimating subsequent episodes of pain.
2020: Urología Mexicana en tiempos de COVID-19. Revisión de la literatura y actualización de la pandemia ocasionada por COVID-19 para el urólogo

Published: February 2022

Background: Coronaviruses are pathogens that affect animals and humans, causing neurologic, respiratory, intestinal, and hepatic diseases. Six coronaviruses are known to cause disease in humans. The current pandemic began in the Chinese city of Wuhan, in the province of Hubei, where the first case of pneumonia was reported on December 12, 2019. In February of 2020, the World Health Organization named the virus COVID-19 and the International Committee on Taxonomy of Viruses named it SARS-CoV-2.
By April 30, 2020, more than 3 000 000 cases were confirmed worldwide, affecting 185 countries, with over 200 000 deaths and approximately 420 000 recoveries.
Relevance: A literature review was carried out to provide urologists with the current status of the disease in Mexico, the pathophysiology of the infectious disease caused by SARS-CoV-2, and the latest updates on the different treatment options for COVID-19.
Conclusions: Because we form part of the healthcare system, it is necessary for urologists to have the latest information on this disease of worldwide importance, given that we are involved with the management of COVID-19 patients at certain hospital centers.
Síndrome de Zinner: revisión actualizada de la literatura basada en un caso clínico asintomático

Clinical case description: A 38-year-old man initially presented with anuria secondary to a right solitary kidney and a stone in the lower third of the ureter that was resolved through laser ureterolithotripsy. As part of his evaluation, extension studies were performed that identified a cyst in the left seminal vesicle.
Relevance: Due to the mutual embryologic origins of the seminal vesicle, vas deferens, and ureteric bud, developmental alterations of the mesonephric duct (Wolffian duct) and the absence of the ureteric bud during the first trimester of gestation are associated with ipsilateral renal agenesis and ejaculatory duct atresia that will later progress to cystic dilation of the seminal vesicle.
Conclusions: Zinner syndrome was first described in 1914 and it continues to be a rare condition worldwide. In fact, only approximately 200 cases have been reported in the literature.

Published: February 2022

Clinical case description: A 71-year-old man that received injections of mineral oil and a multivitamin complex in the subcutaneous tissue and corpora cavernosa of the penis, for 8 months, presented with penile deformity and progressive edema of the dorsal region. He came to our hospital 4 days after the lesion had been excised, presenting with necrosis of the penile skin and purulent drainage, requiring resection and debridement of the necrotic tissue.
Relevance: The unauthorized injection of substances into the penis for cosmetic or sexual purposes has been on the rise in recent years.
Clinical implications: Penile paraffinoma is a reaction caused by the injection of foreign substances into the penis. Said injections often produce complications that can appear months or years after application and they can be life-threatening.
Conclusions: The injection of foreign substances into the subcutaneous tissue of the penis can produce severe and devastating complications. Opportune treatment and multidisciplinary management are key to satisfactory patient progression.

Aim: To know the epidemiology, treatment, and follow-up of patients with prostate cancer at the Nuevo Hospital Civil de Guadalajara “Dr. Juan I. Menchaca”.
Materials and methods: A retrospective, descriptive, observational study was conducted on 196 patients with prostate cancer that were seen within the time frame of 2015 and 2020 at the Nuevo Hospital Civil de Guadalajara “Dr. Juan I. Menchaca”.
Results: Of the 196 cases analyzed, mean age at disease presentation was 72.02 years (±8.77), 53.5% did not have a primary school educational level, and 87.7% had no formal employment. Mean body mass index was 25.43 kg/m2 (±3.13) and the most frequent risk factors were smoking, high blood pressure, and diabetes mellitus. Mean prostate-specific antigen level before treatment was 17.59 ng/ml. Of the cases treated, 31.07% underwent surgery, 55.05% received hormone therapy, and 1.02% were under surveillance. Only 12 cases (6.12%) of death were associated with prostate cancer and 37.75% of the study population was lost to follow-up.
Study limitations: Sample size, single-center study.
Value: Ours is a recent epidemiologic study on prostate cancer in Guadalajara, Jalisco.
Conclusions: There was a high degree of sociocultural marginalization in the population with prostate cancer analyzed, as well as associated risk factors that limited the indication for treatments with curative intent. Said factors negatively impacted adequate patient follow-up.
