ABSTRACT
Purple urine bag syndrome is an uncommon but particularly striking phenomenon observed in people with urinary catheters and co-existent urinary tract infections. A chemical reaction between plastic and certain bacterial enzymes results in an intense purple urine color. We report a 72 year-old male with a cystostomy. A purple coloration of his urinary drainage bag and tubing was noted in the context of a urinary tract infection caused by Citrobacter freundii.

Introduction To determine the parameters affecting the outcome of ureteroneocystostomy (UNC) procedure for vesicoureteral reflux (VUR). Materials and Methods Data of 398 patients who underwent UNC procedure from 2001 to 2012 were analyzed retrospectively. Different UNC techniques were used according to laterality of reflux and ureteral orifice configuration. Effects of several parameters on outcome were examined. Disappearance of reflux on control VCUG or absence of any kind of UTI/symptoms in patients without control VCUG was considered as clinical improvement. Results Mean age at operation was 59.2 ± 39.8 months and follow-up was 25.6 ± 23.3 months. Grade of VUR was 1-2, 3 and 4-5 in 17, 79, 302 patients, respectively. Male to female ratio was 163/235. UNC was performed bilaterally in 235 patients and intravesical approach was used in 373 patients. The frequency of voiding dysfunction, scar on preoperative DMSA, breakthrough infection and previous surgery was 28.4%, 70.7%, 49.3% and 22.4%, respectively. Twelve patients (8.9%) with postoperative contralateral reflux were excluded from the analysis. Overall clinical improvement rate for UNC was 92%. Gender, age at diagnosis and operation, laterality and grade of reflux, mode of presentation, breakthrough infections (BTI) under antibiotic prophylaxis, presence of voiding dysfunction and renal scar, and operation technique did not affect the surgical outcome. However, the clinical improvement rate was lower in patients with a history of previous endoscopic intervention (83.9% vs. 94%). Postoperative UTI rate was 27.2% and factors affecting the occurrence of postoperative UTI were previous failed endoscopic injection on univariate analysis and gender, preoperative BTI, postoperative VUR state, voiding dysfunction on multivariate analysis. Surgery related complication rate was 2% (8/398). These were all low grade complications (blood transfusion in 1, hematoma under incision ...

To report a case of congenital pelvic arteriovenous malformation [pAVM] with urinary retention. A 39-year-old male patient presented with inability to void urine for 8 h. He did not have a history of dysuria or fever, but had increasing urinary frequency and difficulty in voiding over 2 years. Examination revealed a suprapubic mass without external signs of vascular anomaly. A huge, soft, irregular, non-pulsating mass was felt rectally. This mass did not disappear on urinary bladder decompression. Subsequent ultrasound and CT scan revealed pAVMs filling most of the pelvic cavity. To our knowledge, this is the first report of a male patient with congenital pAVM presenting with urinary retention, emphasizing the need for a high index of suspicion for pAVM to avoid potential severe bleeding during suprapubic catheterization for urinary drainage

El síndrome de retención urinaria postoperatorio es una complicación frecuente en la cirugía vaginal y para obviarlo, en muchos centros se propicia el uso de drenaje vesical transuretral por tres a cinco dias, con o sin reeducación vesical. Con el fin de determinar si el tiempo de permanencia del drenaje y la reeducación vesical influyen sobre la ocurrencia de este síndrome, se estudiaron en forma prospectiva y randomizada 106 pacientes sometidas a cirugía vaginal en nuestro servicio, divididas en tres grupos: el primero constituído por 36 pacientes a las que se les retiró el drenaje vesical a las 24 horas; el segundo compuesto por 37 pacientes en las que el drenaje fue retirado a las 72 horas y el tercero que reunió a 33 pacientes en las que la sonda fue retirada a las 72 horas previa reeducación vesical. Nuestros resultados muestran que las pacientes que presentaron con menor frecuencia retención urinaria postoperatoria, fueron aquellas que tuvieron un menor tiempo de drenaje vesical (24,3 por ciento vs 30,7 por ciento y 43 por ciento) por lo que se concluye que el mantener la sonda Foley por más de 24 horas y realizar reeducación vesical, no disminuye la frecuencia del síndrome de retención urinaria y que sólo constituye un mayor riesgo de infección urinaria y de prolongación del tiempo de hospitalización
