RESUMEN
Purpose: To compare the perioperative complication rate obtained with the transperitoneal laparoscopic radical prostatectomy (TLRP) and with the extraperitoneal LRP (ELRP) during the learning curve (LC). Materials and Methods: Data of the initial 40 TLRP (Group 1) were retrospectively compared with the initial 40 ELRP (Group 2). Each Group of patients was operated by two different surgeons. Results: The overall surgical time (175 min x 267.6 min; p < 0.001) and estimated blood loss (177.5 mL x 292.4 mL; p < 0.001) were statistically better in the Group 1. Two intraoperative complications were observed in Group 1 (5 percent) represented by one case of bleeding and one case of rectal injury, whereas four complications (10 percent) were observed in Group 2, represented by two cases of bleeding, one bladder and one rectal injuries (p = 0.675). Open conversion occurred once in each Group (2.5 percent). Overall postoperative complications were similar (52.5 percent x 35 percent; p = 0.365). Major early postoperative complications occurred in three and in one case in Group 1 and 2, respectively. Group 1 had two peritonitis (fecal and urinary), leading to one death in this group. Conclusions: No statistical differences in overall complication rates were observed. The transperitoneal approach presented more serious complications during the early postoperative time and this fact is attributed to the potential chance of intraperitoneal peritonitis not observed with the extraperitoneal route.

The incidence of transitional cell carcinoma (TCC) in patients submitted to hemodialysis is low. The presence of TCC with sarcomatoid features in this cohort is even scarcer. Herein, we describe a very rare case of synchronous multicentric muscle invasive bladder carcinoma with prostate invasion in a hemodialysis patient, submitted to complete en bloc urinary exenteration.

OBJECTIVE: Compare two different techniques for laparoscopic live donor nephrectomy (LDN), related to the operative costs and learning curve. MATERIALS AND METHODS: Between April/2000 and October/2003, 61 patients were submitted to LDN in 2 different reference centers in kidney transplantation. At center A (CA), 11 patients were operated by a pure transperitoneal approach, using Hem-O-Lokomicron clips for the renal pedicle control and the specimens were retrieved manually, without using endobags. At center B (CB), 50 patients were also operated by a pure transperitoneal approach, but the renal pedicles were controlled with endo-GIA appliers and the specimens were retrieved using endobags. RESULTS: Operative time (231 ± 39 min vs. 179 ± 30 min; p < 0.000), warm ischemia time (5.85 ± 2.85 min vs. 3.84 ± 3.84 min; p = 0.002) and blood loss (214 ± 98 mL vs. 141 ± 82 mL; p = 0.02) were statistically better in CB, when compared to CA. Discharge time was similar in both centers. One major complication was observed in both centers, leading to an open conversion in CA (9.1 percent). One donor death occurred in CB (2 percent). Regarding the recipients, no statistical difference was observed in all parameters analyzed. There was an economy of US$1.440 in each procedure performed in CA, when compared to CB. CONCLUSIONS: Despite the learning curve, the technique adopted by CA, showed no deleterious results to the donors and recipients when compared with the CB. On the other hand, this technique was cheaper than the technique performed in the CB, representing an attractive alternative for LDN, mainly in developing centers.

Metastatic vesical tumors are rare, and constitute approximately 1 percent of all neoplasias affecting this organ. The authors report the case of a 63-year old woman with vesical metastasis of gastric adenocarcinoma. Patient presented signs of cachexia and complained of left lumbar pain and dysuria unresponsive to antibiotic therapy for approximately 5 months. She reported a previous partial gastrectomy due to ulcerative undifferentiated gastric adenocarcinoma 1 year and 9 months before. Cystoscopy revealed an extensive vegetative lesion in bladder, occupying its entire mucosal surface. The biopsy revealed metastatic signet-ring cell adenocarcinoma.
