Laparoscopic diverticulectomy: A systemised technique. / Diverticulectomía laparoscópica: técnica sistematizada.

OBJECTIVES: To present an original technique for laparoscopic vesical diverticulectomy without the need for dissecting the diverticular wall, thereby making the procedure safe and significantly simpler. MATERIAL AND METHODS: Four patients were operated on between September 2014 and April 2016. The diagnosis was made by ultrasonography in all cases, and the study included blood and urine analyses with urine cultures, urine cytology, contrast-enhanced CT scans, prostate symptom questionnaire (International Prostate Symptom Score), flowmetry and cystoscopy. One case required transurethral prostate resection in a first time. RESULTS: The mean age of the patients was 64 years (range: 56-71). The mean diverticulum size was 4cm (range: 3-6). The location was retrotrigonal in all cases, on the left side in 2 cases, right retromeatic in 1 case and near the midline in 1 case. The mean surgical time was 146min (range, 120-180), shortening for each new case. There were no significant bleeding, complications or conversion to open surgery in any of the cases. The postoperative period had no incidences. The hospital stay was 3 days in 3 cases and 48h in the other case (mean, 3.5 days). The catheter was withdrawn in the outpatient clinic at 14 days. CONCLUSIONS: The initial experience with the technique described above shows it to be safe and reproducible, with results similar to other current laparoscopic techniques. Avoiding the dissection of the diverticular wall significantly reduces the technical difficulty of the procedure.

Umbilical laparoendoscopic partial cystectomy.

OBJECTIVE: To present our center's experience in single-port umbilical laparoendoscopic partial cystectomies, in both benign and malignant pathologies. Patient characteristics, perioperative aspects and the surgical techniques used are reviewed. MATERIAL AND METHOD: Since May 2012, five patients have undergone a transumbilical single-port laparoendoscopic partial cystectomy with curved equipment through a reusable multichannel system and a 3.5mm accessory trocar. Patients were three males and two females aged between 28 and 78 (median: 44±42.5) years. The etiologies were endometriosis (in 2 cases), a tumor in the diverticulum, a congenital bladder diverticulum and ureterocele (1 case of each). RESULTS: Median surgery time was 273±163.4minutes, and intraoperative bleeding 250±175ml. None of the patients required transfusion. The postoperative period was uneventful, with good results and no complications. The hospital stay was 3±1 days. With monitoring of 20±17.5 months, morphological and functional recovery in the bladder and ureter was confirmed in all cases and the patient with neoplastic disease was disease-free more than 2 years after the surgery. CONCLUSIONS: An umbilical laparoendoscopic partial cystectomy represents a viable surgical option and ensures that excellent surgical and cosmetic results are achieved.

Diverticulitis vesical: reporte de un caso y revisión de la literatura / Bladder diverticulitis: case report and literature review

Se presenta un caso de diverticulitis vesical en un paciente de 60 años con antecedente de obstrucción crónica al tracto de salida vesical (estenosis uretral), quien consulta por dolor pelviano inespecífico. Por lo anterior se realiza Resonancia Magnética (RM) de pelvis, que demuestra la presencia de un divertículo vesical de pared engrosada con cambios inflamatorios, los que comprometen además, la grasa peri-vesical. Este divertículo había sido detectado en RM pelviana un año antes. Se comenta el caso clínico, sus hallazgos a la RM y revisión de la literatura...

We report a case of bladder diverticulitis in a 60 years old patient with a history of chronic lower urinary tract obstruction (urethral stricture), who consulted for nonspecific pelvic pain. Pelvic magnetic resonance imaging (MRI) was obtained, demonstrating the presence of a bladder diverticulum with a thick wall and inflammatory changes involving the perivesical fat. The diverticulum had been detected on pelvic MRI a year earlier. We discuss the clinical case, the MRI findings and a review of the literature....

Divertículo vesical congénito gigante / Giant congenital vesical diverticulum

Los divertículos vesicales congénitos son infrecuentes. En el adulto generalmente se detectan asociados a factores obstructivos a la salida vesical, y se manifiestan por sepsis urinaria recurrente en la mayoría de los casos. Se presenta un paciente del sexo masculino de 67 años de edad, que asistió a consulta por infecciones urinarias bajas a repetición. Al examen físico se constató la presencia de un tumor ovoide de unos 10 cm de diámetro, móvil, no doloroso y con matidez a la percusión, en proyección del hipogastrio y lateralizado hacia la izquierda; la próstata al tacto rectal era de tamaño normal y de consistencia fibroelástica. En el ultrasonido, la uretrocistografía y la tomografía axial computadorizada, se evidenció un divertículo vesical gigante, con su cuello hacia la pared lateral izquierda de la vejiga. Se confirmó mediante la cistoscopia y se procedió a su exéresis por cirugía convencional. El informe histopatológico reveló la existencia de las capas mucosa, muscular y adventicia en su pared, de manera que se corroboró su origen congénito. La evolución del paciente resultó satisfactoria. La exéresis total de los divertículos vesicales congénitos de gran tamaño, constituye la solución definitiva para aquellos pacientes que presentan sepsis urinaria recurrente, en ausencia de factores obstructivos al vaciamiento vesical

Congenital vesical diverticula are infrequent. In adult persons generally are detected in association with obstructive factors for vesical outlet with a recurrent urinary sepsis as manifestation in most cases. This is the case of a male patient aged 67 seen in consultation due to repeated low urinary infections. In physical examination was confirmed the presence of a 10 cm ovoid, mobile and no-painful tumor and with a dull sound to percussion in hypogastrium projection and lateralized to left; at rectal tactus it was of normal size and with a fibroelastic consistency. Ultrasound, urethrocystography and computerized axial tomography evidenced a giant vesical diverticulum with its neck to left lateral wall of bladder confirmed by cystoscopy and exeresis by conventional surgery. Histopathological report showed the presence of mucous and muscular layers, and adventitia in its wall, thus confirming its congenital origin. Patient's course was satisfactory. Total exeresis of big congenital vesical diverticula is the definite solution for those patients presenting with recurrent urinary sepsis in the absence of obstructive factors to vesical voiding

Hidronefrosis por obstrucción vesical en paciente pediátrico / Hydronephrosis due to vesical obstruction in a pediatric patient

La hidronefrosis es la dilatación del sistema colector renal; especialmente de la pelvis y de los cálices renales asociadas a una atrofia progresiva del riñón causada por una obstrucción del flujo de la orina; No siempre es debida a obstrucción y asimismo la obstrucción no siempre produce hidronefrosis. Se clasifica en ligera, moderada y severa de acuerdo al grado de lesión del parénquima renal. Los divertículos vesicales aparecen como protusiones de la mucosa vesical a través de las bandas del músculo detrusor; son infrecuentes y de forma habitual aparecen en niños varones. Se presenta el estudio ecográfico de un caso de hidronefrosis severa, congénita en un niño de 8 años por la obstrucción de un divertículo vesical, donde se observa claramente la atrofia renal; la obstrucción uretero vesical representa el 8% de todos los casos de hidronefrosis en recién nacidos.

The hydronephrosis is the dilation of the renal system. Hydronephrosis consists of the dilation of the pelvis and of the renal chalices associated to a progressive atrophy of the kidney caused by an obstruction to the flow of the urine. It is not always due to obstruction and also the obstruction doesn't always produce hydronephrosis. It can be classified in mild, moderate and severe according to the degree of lesion in the renal tissue. The diverticulums appear as protrusions of the bladder mucous vesicle through the bands of the detrusor muscle, they are uncommon and they appear in male children. The Image study of a severe clinical case of congenital hidronefrosis in a 8 year-old boy due to the obstruction of a diverticulum where we can observe clearly the renal atrophy. The obstruction uretero-vesicle represents 8% of all the cases of hydronephrosis in recently born.
