Curva de aprendizaje de la ecografía renal en una unidad docente pluriprofesional / Renal ultrasound learning curve performed in a multiprofessional teaching unit

Introducción: El objetivo de esta experiencia fue analizar un módulo formativo inserto en la práctica asistencial de un departamento de urología con la participación de enfermeras especializadas en ecografía urológica como monitoras. Material y métodos: Participaron en el estudio 12 estudiantes de medicina carentes de cualquier conocimiento de ultrasonografía. Su formación corrió a cargo de dos enfermeras con gran experiencia en ecografía. Después de dos sesiones de entrenamiento, se analizó la concordancia entre sus hallazgos en la exploración de los riñones y los de un urólogo especialista. Para analizar la experiencia desde todos los puntos de vista, se exploró el grado de aceptación del módulo formativo por parte de los usuarios y la tolerancia de los profesionales involucrados en términos de síndrome de desgaste profesional (SDP). Por último, se calcularon los costes. Resultados: El coeficiente kappa de concordancia entre el experto y los estudiantes fue bueno (≥ 0,67) en el 58,3% de los casos. No se detectaron rasgos de SDP entre los involucrados en la experiencia. La participación de las enfermeras como monitoras redujo el coste del operativo en un 25% en comparación con los costes en los que se podría haber incurrido caso de docentes urólogos senior. Conclusiones: Las enfermeras pueden proporcionar los rudimentos de la formación en ecografía a legos en la materia. La exploración de individuos con cálculos renales o ureterohidronefrosis se traduce en una mayor concordancia entre observadores. El usuario involucrado acepta de buen grado la experiencia. El operativo resulta inocuo para el personal participante.

Introduction: The objective of this experience was to analyze a training module inserted in the care practice of an urology department, with the participation of nurses specialized in urological ultrasound as monitors. Material and methods: Twelve medical students with no knowledge of ultrasonography participated in the study. His training was carried out by two nurses with extensive experience in ultrasound. After two training sessions, the agreement between their kidney examination findings and those of a specialist urologist was analyzed. To analyze the experience from all points of view, the degree of acceptance of the training module by the users was explored, as well as the tolerance of the professionals involved in terms of professional burnout syndrome (PBS). Finally, the costs of the operation were calculated. Results: The kappa coefficient of agreement between the expert and the students was good (≥ 0.67) in 58.3% of the cases. No traits of PBS were detected among involved in the experience. The participation of nurses as monitors reduced the cost of the operation by 25% compared to the costs that could have been incurred if they had been senior urologist teachers. Conclusions: Nurses can provide the rudiments of sonography training to laymen. Examination of individuals with kidney stones or ureterohydronephrosis results in greater interobserver agreement. In general, the user involved willingly accepts the experience. The operation is harmless for the participating staff.

Parastomal hernia after radical cystectomy. Incidence, natural history and predictive factors - A single center study.

PURPOSE: Parastomal hernia (PH) is one of the most frequent complications after stoma creation. Our objective was to analyze the incidence, evolution and predictive factors of PH in Bricker-type urinary diversion. PATIENTS AND METHODS: Case series analysis of 125 patients submitted to radical cystectomy and ileal conduit diversion for cancer in a single center during 2006-2021. Patient's record and imaging tests were reviewed to identify those suffering PH. Moreno-Matías classification was used to define radiological PH (rPH). Demographic and preoperative characteristics of the patients, surgical details and postoperative complications were recorded. Univariate and multivariate analyses were conducted to determine the effect of each predictive variable on the development and progression of PH. RESULTS: 21.6% of patients developed PH (median follow-up 37 months). Incidence increased with follow-up time (15.2% at 1 year, 20.8% at 2 years). BMI ≥ 25 (Expß 8.31, 95% CI 1.06- 65.18, p = 0.04), previous midline laparotomy (Expß 6.74, 95% CI 1.14-39.66, p = 0.04) and wound infection (Expß 3.87, 95% CI 1.21-12.33, p = 0.02) were significantly associated with PH. Half of the patients with hernia had symptoms, 25.9% requiring surgical correction. 46% of type 1 hernias and 40% of type 2 hernias progressed to grade 3 with a median of 11 months. No variable was associated with radiological progression. CONCLUSIONS: This study proved 3 independent factors (overweight, laparotomy and wound infection) that increase the risk of developing PH.

Cirugía de rescate de extrusión de prótesis hidráulica de pene mediante protocolo de Mulcahy modificado. Revisión de la literatura a propósito de un caso / Salvage surgery of hydraulic penile prosthesis by modified Mulcahy protocol. Case report and literature review

La extrusión de una prótesis peneana es indicador de infección e implica su retirada, provocando fibrosis y acortamiento del pene.Presentamos el caso de un varón de 62 años, al que implantamos una prótesis hidráulica, y tres semanas después sometimos a cirugía de rescate por extrusión de la bomba de activación. Tras extraer la prótesis, lavamos las cavidades con cuatro diluciones. La primera al 50% de agua oxigenada; la segunda al 50% de povidona yodada; la tercera con 1 g de cefazolina y 40 mg de tobramicina, la cuarta con 80 mg de gentamicina y 500 mg de vancomicina. En el acto implantamos una prótesis maleable bañada en las soluciones antibióticas.El posoperatorio fue satisfactorio. Un año después, presenta una adecuada longitud peneana y aspecto estético, manteniendo relaciones sexuales satisfactorias.El rescate quirúrgico mediante el lavado con soluciones antisépticas e implante de prótesis maleable, minimiza el riesgo de reinfección, preservando la función sexual.

Glandectomía con injerto cutáneo de muslo / Glandectomy with cutaneous thigh graft

El cáncer de pene es una neoplasia que afecta predominantemente a varones en la sexta década de la vida, con una incidencia de 0,3-1 por 100.000 habitantes. Tradicionalmente, el tratamiento de la lesión primaria ha consistido en la amputación total o parcial del pene. Sin embargo, el impacto psicológico y funcional ha influido en el desarrollo de técnicas de preservación. Presentamos a 2 pacientes con lesiones localizadas en el glande, diagnosticados mediante biopsia de carcinoma epidermoide. Ambos pacientes fueron tratados mediante glandectomía y reconstrucción con injerto libre de piel de muslo. La anatomía patológica fue de carcinoma epidermoide superficial. Seis meses después los pacientes se encuentran libres de enfermedad y satisfechos con el resultado de la intervención. En nuestra opinión, esta técnica permite obtener un adecuado resultado cosmético y funcional, sin perjuicio del control oncológico, y sin incrementar la morbilidad ni el tiempo operatorio

Penile cancer is a neoplasm that predominantly affects males in the sixth decade of life, with an incidence of .3-1 per 100,000. Traditionally, the treatment of the primary lesion has consisted of total or partial amputation of the penis. However, the psychological and functional impact has influenced the development of preservation techniques. We present 2 males with lesions on the glans diagnosed by biopsy of squamous cell carcinoma. The patients underwent glandectomy and reconstruction with free thigh skin graft. The pathological anatomy was superficial squamous cell carcinoma. 6 months later the patients are free of disease and satisfied with the result of the intervention. In our opinion, this technique enables an adequate cosmetic and functional result without affecting oncological control and without increasing morbidity or operative time

A prospective randomized study comparing bipolar plasmakinetic transurethral resection of the prostate and monopolar transurethral resection of the prostate for the treatment of Benign Prostatic Hyperplasia: efficacy, sexual function, Quality of Life, and complications

ABSTRACT Objective: To generate high-quality data comparing the clinical efficacy and safety profile between monopolar transurethral resection of the prostate (M-TURP) and bipolar plasmakinetic resection of the prostate (PK-TURP) for benign prostatic hyperplasia (BPH). Materials and Methods: Prospective, randomized, single-blinded study conducted in a tertiary-care public institution (Dec/2014-Aug/2016). Inclusion criteria: prostate of <80g in patients with drug-refractory lower urinary tract symptoms (LUTS), complications derived from BPH, or both. Exclusion criteria: a history of pelvic surgery/radiotherapy, neurogenic bladder dysfunction or documented/suspected prostate carcinoma. Treatment efficacy evaluated at 1, 3, 6 and 12 months. Efficacy outcomes: international prostate symptom score (IPSS), quality-of-life (QoL) score, international index of erectile function-5 (IIEF-5), maximum urinary flow rate (Qmax), postvoid residual urine (PVRU) volume, and prostate volume (PV). Complications and sequelae also assessed. Comparisons performed with parametric/non-parametric tests. Results: Out of the 100 hundred patients, 84 qualified for the analysis (45 M-TURP/39 PK-TURP). No significant differences found in baseline characteristics or operative data, except for a longer operative time in PK-TURP (MD:7.9min; 95%CI:0.13-15.74; p=0.04). No differences found in IPSS, Qmax or PVRU volume. QoL score at 12 months was higher in PK-TURP (MD:0,9points; 95%CI:0.18-1.64; p=0.01). No differences in sexual function, PV, complications or sequelae were found. This study is "rigorous" (Jadadscale) and has a low risk of bias (Cochrane-Handbook). Conclusions: Based on this controlled trial, there is not significant variation in effectiveness and safety between M-TURP and PK-TURP for the treatment of BPH. The small difference in QoL between PK-TURP and M-TURP at the one-year follow-up is not perceivable by the patients and, therefore, not clinically relevant.

[Laparoscopic management of horseshoe kidney stones.] / Tratamiento laparoscópico de la litiasis en el riñón en herradura.

OBJECTIVE: Horseshoe kidney is the most common renal fusion anomaly. Its peculiar anatomical characteristics increase the risk of lithiasis formation and always entails a surgical challenge for its treatment. MATERIAL AND METHODS: We present the cases of men with horseshoe kidneys diagnosed by CT one case of alarge pyelic lithiasis with others of a smaller size in the calyces, and the other of a big solitary lithiasis in renal pelvis. RESULTS: We performed a laparoscopic pyelolitectomy to remove the pyelic lithiasis and we used a flexible cystoscope through a trocar to extract the calyceal stones. The postoperative period was uneventful without evidence of urinary leakage or residual lithiasis. CONCLUSIONS: The laparoscopic approach to lithiasisis a suitable alternative in especially complex cases such as horseshoe kidney. The use of a flexible cystoscope allows to navigate through the renal cavities and extract the lithiasis which cannot be accessed through laparoscopic instruments, improving the efficiency of this approach.

Comparación entre resección monopolar vs. resección bipolar transuretrales de próstata y su impacto sobre la función sexual / Comparison of monopolar versus bipolar transurethral resection of the prostate: Evaluation of the impact on sexual function

OBJETIVOS: Evaluar los efectos de la resección transuretral de próstata (RTUP) monopolar (M-RTUP) y bipolar (B-RTUP) sobre la función sexual general. MÉTODOS: De diciembre de 2014 a septiembre de 2016, 100 candidatos elegibles con hiperplasia benigna de próstata fueron reclutados prospectivamente y aleatorizados 1:1 en 2 grupos M-RTUP/B-RTUP (58 y 42 pacientes, respectivamente) y seguidos al mes, 3 y 6 meses. Se realizó un análisis univariado y multivariado utilizando la prueba de chi cuadrado y un modelo de regresión logística. Analizamos la edad, los antecedentes médicos de hipertensión arterial y diabetes, los antecedentes de tabaquismo, el volumen prostático preoperatorio, la escala de síntomas prostáticos, la evaluación de la función sexual, la experiencia del cirujano, los gramos resecados, el porcentaje de tejido resecado y la presencia de eyaculación retrógrada. Los síntomas prostáticos y la evaluación de la función eréctil (FE) se cuantificaron utilizando puntuaciones de IPSS autoadministradas y IIEF-5, respectivamente, al inicio del estudio y en cada visita posterior. RESULTADOS: La edad promedio fue de 66 años (50-82). No se encontraron diferencias estadísticas entre ambos grupos con respecto a comorbilidades médicas, IPSS preoperatorio e IIEF-5. El volumen prostático medio fue de 37,2cm3 (10-68) y la cantidad media de tejido resecado fue de 11,75g (6-58). Al inicio del estudio, el 77,6% de los pacientes presentaban STUI graves, y el 50% tenía una disfunción eréctil moderada-grave. El análisis univariado demostró que, en ambos grupos, los antecedentes de diabetes mellitus, la edad y el IIEF-5 preoperatorio se asociaron con una peor FE. Sin embargo, el análisis multivariado reveló que la edad fue el único factor asociado con una peor FE. Estos resultados fueron similares a los 3 y 6 meses postoperatorios. No encontramos una asociación entre la experiencia del cirujano, el tipo de energía empleada o el porcentaje de tejido resecado con el desarrollo de eyaculación retrógrada postoperatoria (52%). En el primer mes postoperatorio, el 44% de los pacientes aún referían síntomas prostáticos moderados y el 50% tenían disfunción eréctil grave mantenida a los 6 meses en ambos grupos. CONCLUSIONES: No existen diferencias estadísticamente significativas con respecto al tipo de energía empleada y los cambios en la función sexual global. La edad es el único factor que se asocia a una peor FE

OBJECTIVES: To assess the effects of monopolar transurethral resection of the prostate (M-TURP) and bipolar TURP (B-TURP) on overall sexual function. METHODS: From December 2014 to September 2016, 100 eligible candidates with benign prostatic hyperplasia were prospectively recruited and randomized 1:1 into M-TURP/B-TURP arms (58 and 42 patients, respectively) and followed up at 1, 3 and 6 months. A univariate and multivariate analyses using the chi-squared test and a logistic regression model were performed. We recorded the age, medical conditions such as hypertension and diabetes, history of smoking, preoperative prostatic volume, prostatic symptoms scale, sexual function assessment, surgeon experience, resected grams, percentage of resected tissue and presence of retrograde ejaculation. Prostatic symptoms and erectile function (EF) assessment were quantified using self-administered IPSS scores and IIEF-5, respectively, at baseline and in each subsequent visit. RESULTS: Mean age was 66 years (50-82). No statistical differences were found between both groups regarding medical comorbidities, preoperative IPSS and IIEF-5. Mean prostatic volume was 37.2 cm3 (10-68) and mean amount of resected tissue was 11.75g (6-58). At baseline 77,6% of patients has severe LUTS, and 50% has moderate-severe erectile dysfunction. Univariate analyses show that in both groups, history of diabetes mellitus, age and preoperative IIEF-5 were associated with poor EF. However, multivariate analyses revealed that age was the only factor associated with a poor EF. These results were similar at 3 and 6 postoperative months. We did not find an association between surgeon experience, source of energy employed or percentage of resected tissue with the development of postoperative retrograde ejaculation (52%). At first postoperative month, 44% of patients were still referring moderate prostatic symptoms and 50% had severe erectile dysfunction maintained at 6 months in both groups. CONCLUSIONS: There were no differences between the source of energy employed and changes on overall sexual function. Age is the only factor associated with a poor EF status

[Long term results of congenital penile curvature treated with cavernosa corpora rotation.] / Seguimiento a largo plazo de la incurvación peneana congénita tratada mediante rotación de los cuerpos cavernosos.

INTRODUCTION: Congenital penile curvature (PCC) is a disorder caused by an alteration in the embryonic development of the urethra and the corporacavernosa, which causes difficulty in penetration, requiring surgical correction when inter course is impossible. OBJECTIVE: To analyze the results of the surgical treatment of the IPC by means of rotation of the corpora cavernosa (RCC) described and modified by Shaeer. PATIENTS AND METHODS: Ten patients diagnosed with PCC with impossibility to inter course, were operated in a period of 36 months. Prior to the intervention,we applied the IIEF-5 questionnaire, measured the length of the penis and the angle of curvature throughself-photographs in three projections. By subcoronal approach,we perform denudation of the penis. On both sides of the urethra we incised Buck's fascia and released the neurovascular bundle from the ventral to the dorsal side. We generate an artificial erection evidencing the curvature. On the dorsal aspect of both corpora cavernosa, we made two incisions in the external longitudinal layer of the tunica albuginea. We sutured the internal and external edges of both incisions together with a 4/0 non-reabsorbable monofilament continuous suture, checking the correction of the curvature by means of an artificial erection. The patients were discharged the day after the intervention. The penile length and curvature were determined in the sixth month, and the IIEF-5 questionnaire. For the comparison of means we used the Mann-Whitney U test.  RESULTS: The mean age was 26.8 years. The average follow-up was 20.7 months (12-31) and the median was 24. Before the intervention, the average curvature was 68.5° (50-90°); the average length 14.2 cm (10-18) and the IIEF-5 of 21. After surgery, the average length was 13.7 cm, the residual curvature the IIEF-5 of 25. There were no statistically significant differences between pre and postoperative penile length,(p=0.08). Nine patients assured that they would under go the same intervention again. CONCLUSIONS: RCC is an effective therapeutic alternative to the techniques of plication or lengthening of the tunica albuginea for the treatment of PCC, main tainingits long-term results.

INTRODUCCIÓN: La incurvación peneana congénita (IPC) es un trastorno originado por una alteración en el desarrollo embrionario de la uretra y los cuerpos cavernosos, que condiciona dificultad para la penetración, precisando corrección quirúrgica cuando imposibilita el coito. OBJETIVO: Analizar los resultados del tratamiento quirúrgico de la IPC mediante rotación de los cuerpos cavernosos(RCC) descrita y modificada por Shaeer. PACIENTES Y MÉTODOS: Diez pacientes diagnosticados de IPC con imposibilidad para el coito, fueron intervenidos en un período de 36 meses. Previo a la intervención aplicamos el cuestionario IIEF-5, medimos la longitud del pene y el ángulo de incurvación mediante autofotografías en tres proyecciones. Mediante abordaje subcoronal realizamos el denudamiento del pene. A ambos lados de la uretra incidimos la fascia de Buck y liberamos el paquete vasculonervioso desde la cara ventral hasta dorsal. Generamos una erección artificial evidenciando la incurvación. En la cara dorsal deambos cuerpos cavernosos realizamos dos incisiones longitudinales en la capa longitudinal externa de la túnica albugínea. Suturamos los bordes internos y externosde ambas incisiones entre sí con una sutura continuade monofilamento irreabsorbible de 4/0, comprobando mediante una erección artificial la corrección de la incurvación. Los pacientes fueron dados de alta al día siguiente de la intervención. Al sexto mes se determinaron la longitud e incurvación peneanas, y el cuestionario IIEF-5. Para la comparación de medias utilizamos el test de la U de Mann-Whitney. RESULTADOS: La edad media fue 26,8 años. El seguimiento promedio fue 20,7 meses (12-31) y la mediana 24. Antes de la intervención la incurvación media fue 68,5° (50-90°); la longitud media 14,2 cm (10-18) yel IIEF-5 de 21. Tras la intervención la longitud media fue 13,7 cm, la incurvación residual 25. No existieron diferencias estadísticamente significativas entre la longitud peneana pre y postquirúrgica,(p=0,08). Nueve pacientes aseguraron que volverían asometerse a la misma intervención. CONCLUSIONES: La RCC constituye una alternativa terapéutica eficaz a las técnicas de plicatura o alargamiento de la túnica albugínea para el tratamiento de la IPC, manteniendo sus resultados a largo plazo.
