laparoscopic radical nephrectomy of angiomyolipoma with renal vein involvementBackground: Angiomyolipomas associated with tuberous sclerosis may invade the renal vein and generate intramural thrombi. case report: We report a 36-years-old woman, consulting for left flank pain. CT scan showed a large tumor in the left kidney consistent with the diagnosis of infiltrating renal angiomyolipoma with tumor invasion of the vein. Laparoscopic nephrectomy was performed, with removal of tumor thrombus. The operative time was 127 minutes and estimated bleeding 20 ml. There were no intraoperative or postoperative complications. The patient is currently asymptomatic after 12 months of follow up. The pathological study of the surgical piece showed a renal angiomyolipoma with invasion of the kidney and a solid tumor in the lumen of the renal vein

radical cystectomy for bladder cancer in a state teaching hospital: analysis of perioperative outcomes introduction: A number of patients have been studied after undergoing Radical Cystectomy (RC) for bladder cancer, to review prognostic factors and analyze perioperative outcomes. A contemporary benchmark was established for future comparisons. material and methods: Retrospective study of 46 patients that underwent RC for bladder cancer between July 2003 and September 2012, assessing demographic characteristics, comorbidities, anesthetic risk and clinical status, interval between transurethral resection (TUR) and cystectomy, operative times, bleeding and transfusions, surgical technique, nutritional management, pathologic findings, hospital stay and complications. Complications were detailed by type and frequency and classified as early (within 30 days) or late. In addition, we used the Clavien-Dindo classification for reporting postoperative complications. Mortality rates at 30, 60 and 90 days after cystectomy were estimated. results: Average patient age was 70 years (49-88) and mean ASA classification was 2.7. The average between TUR and cystectomy was 68.2 days (median = 57.5 days). Mean operative time for cutaneous ureterostomy was 194 minutes, 320 for ileal conduit and 342 for neobladder. 60.8% had pathological stage major than pT 2 and 41% had nodal involvement. There were 19.5% of positive margins. The 23.9% had Clavien-Dindo postoperative complications grade 3 or 4. The 90-day global mortality was 17.3%. Conclusions: CR was associated with a high morbidity and mortality, which seems to be explained by an advanced stage of the disease and the high presence of poor prognostic factors.
