RESUMO
A radical cystectomy, including a pelvic lymphadenectomy, is a standard treatment for a muscle invasive bladder tumor, but it is considered a major operation, with serious complications, and most complications develop in the early postoperative period. After a radical cystectomy, with ileal conduit urinary diversion (ICUD), bleeding is a common and well known complication in the early postoperative period, but rare in the later period. Here we report a case of massive bleeding from an ileal conduit 3 months after a radical cystectomy, with ICUD, due to a rupture of the iliac artery pseudoaneurysm, which was treated by vascular suture of the right iliac artery.

Large bladder masses in children are extremely rare pathological lesions. They can present as a gross hematuria, with irritable or obstructive voiding symptoms and a urinary tract infection. Their differential diagnosis must include for genitourinary malignancies, such as rhabdomyosarcoma, as well as benign inflammatory lesions. A case of a bladder mass in a three-year-old girl is reported, which was finally diagnosed as localized perforated appendicitis.

PURPOSE: Retroperitoneoscopic nephroureterectomy (RNUx), with a bladder cuff excision, has only recently been used to treat patients with upper tract transitional cell carcinomas. We retrospectively evaluated our early experiences, and compared our results to those of a contemporary series of open nephroureterectomies (ONUx), in upper tract transitional cell carcinomas. MATERIALS AND METHODS: We reviewed the records of 7 patients who had undergone a RNUx, with a bladder cuff excision, for a suspicious upper tract transitional cell carcinoma, and 7 who had undergone an ONUx, with a bladder cuff excision. RESULTS: Comparing the results of the RNUx (7 patients) to the ONUx (7 patients) over the same period, we found no significant differences in the body mass index (25.1 versus 25.5kg/m2, p=0.22), specimen weights (155 versus 175gm, p=0.59) and operating time (266 versus 244 min., p=0.20). The RNUx group had significantly reduced estimated blood losses (350 versus 543mL, p=0.01), pain medication requirements (141 versus 232mg, p=0.03) and times to ambulate (21 versus 31 hours, p<0.01). CONCLUSIONS: Our early experiences show that RNUx takes a longer operation time, and is a harder operation compared to ONUx, but it is well tolerated by patients because we can remove the kidney and ureter from a smaller lower abdominal incision. With increased experience, the operating time decreased compared to an ONUx. Thus, a RNUx may be a viable alternative for managing localized transitional cell carcinomas of the upper urinary tract.

An epithelioid angiomyolipoma is an uncommon clinicopathological variant of an angiomyolipoma. A 25-year-old man presented with a huge right renal tumor and underwent a radical nephrectomy. The pathological diagnosis was an epithelioid angiomyolipoma, which showed a positive reaction to the HMB-45 monoclonal antibody and negative to epithelial cell markers. A year later, multiple metastases developed to the liver, lungs and bones. A hepatic lobectomy was performed, and a metastatic epithelioid angiomyolipoma, from the original renal tumor, was pathologically confirmed. The case is presented with a review of the literature.
