Aortic cross-clamping during IVC occlusion prevented hypotension and maintained hemodynamic stability that has required bypass in other series. This surgical treatment with the less extensive approach could result in long-term survival of patients with RCC in whom tumor thrombus extends into the IVC. We recommend that radical nephrectomy and tumor thrombectomy, with or without caval resection, be performed in these patients, with less invasive additional maneuvers.

Aim : To assess the feasibility of our portless endoscopic radical nephrectomy via a single minimum incision, which narrowly permitted extraction of the specimen in the initial 80 patients. Methods : Radical nephrectomy was carried out extraperitoneally in patients with T1-3aN0M0 renal tumors using an endoscope through a single minimum incision without trocar ports and gas. All the instruments used were reusable.Results : The average length of incision, operative time and estimated blood loss were 6.6 cm (range, 4-9 cm), 3. 1 h (range, 1.7-5.6 h) and 324 mL (range, 10-2288 mL), respectively. The complication rate was 2.5% (2/80); complications included injury of the pleura and hemorrhage from the vena cava, both of which were repaired by suture during operation. Transfusion was performed in three patients (3.8%). Average times to oral feeding and walking were both 1.4 days. Wound pain was minimal and analgesics were generally not required by the second postoperative day. In patients with larger incisions (7 cm or more), estimated blood loss increased (approximately 100 mL on average) and oral feeding resumed later (0.3 days on average), relative to patients with smaller incisions (6 cm or less). However, overall results were similar between the two patient groups. In patients with a large tumor (7 cm or greater), operative time did not increase and complications and transfusions were both avoided. Conclusion : Portless endoscopic radical nephrectomy via a single minimum incision is a safe, reproducible, cost-effective and minimally invasive treatment option for patients with T1-3aN0M0 renal tumors.

We propose a three-dimensional 14-core and a three-dimensional 8-core biopsy as efficient first-time biopsy schemes to detect stage T1c and T2 prostate cancer, respectively.

Background : To assess the feasibility of laparoscope-guided minilaparotomy (endoscopic minilaparotomy) for renal cell carcinoma in patients on chronic dialysis. Methods : Endoscopic retroperitoneal minilaparotomy using a 30 ° telescope was carried out through single skin incision (5-8 cm) in eight patients with renal cell carcinoma who were on chronic dialysis. Outcomes of the operations were compared to those in eight patients on chronic dialysis with renal cell carcinoma who underwent standard translumbar radical nephrectomy.Results : Resection of the tumor was successfully completed without complication and the postoperative course was uneventful in both of the treatment groups. No significant difference in mean operative time or mean blood loss was observed between the treatment groups. Wound pain was minimal and analgesics were generally not required in the minilaparotomy group. The endoscopic laparotomy group resumed full diet and began walking earlier than the group that underwent standard radical nephrectomy. Conclusions : Endoscopic minilaparotomy seems to be a valuable alternative treatment for renal cell carcinoma in patients on chronic dialysis.

Switching antiandrogens may be reasonable in prostate cancer with mutant ARs.
