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

Operative morbidity in laparoscopic retroperitoneal lymph node disection in clinical stage A non-seminomatous testis cancerBackground: Retroperitoneal Lymph node dissection is part of the treatment of patients with nonseminomatous germ cell tumors stage I (NSGCT). Aim: To report the immediate surgical outcomes of patients subjected to laparoscopic retroperitoneal lymph node dissection. Material and Methods: Prospective analysis of the surgical outcomes of 118 patients aged 15 to 44 years, who underwent Laparoscopic Retroperitoneal Lymph Node Dissection (L-RPLND) for NSGCT stage I. Results: Median blood loss was 50 cc (range 10-1.000 cc), median operative time was 120 min. (range 60-300 min). Mean hospital stay was 41.4 hours. Twelve patients (10.2%) had operative complications. Ten had vascular injuries (8.5%), one had a duodenal injury (0.85%) and one had an acute pulmonary edema (0.85%). Eight lesions were repaired laparoscopically and three required conversion to open surgery. There was no mortality in this series. Conclusions: L-RPLND had an acceptable complication rate in this series of patients. Most of the complications could be resolved laparoscopically.Key words: Lymph node dissection, laparoscopy, complications, testicular cancer. ResumenIntroducción: La linfadenectomía retroperitoneal lumboaórtica es el método de elección en el tratamiento de los pacientes con cáncer testicular no seminoma en estadío A. Este trabajo muestra los resultados inmediatos de una serie de 118 pacientes operados por vía laparoscópica. Material y Método: Se analizan los resultados quirúrgicos de 118 pacientes portadores de un cáncer testicular no seminoma estadío clínico A. Resultados: La media de edad fue de 29 años. La mediana de sangrado fue de 50 cc, el tiempo quirúrgico tuvo una mediana de 120 minutos y el tiempo de hospitalización tuvo una media de 41,4 horas. Complicaciones intraoperatorias ocurrieron en 12 pacientes (10,2%): 10 lesiones hemorrágicas (8,5%), 1 lesión duodenal (0,85%) y 1 edema pulmonar agudo (0,85%). De las 11 lesiones quirúrgicas, 8 fueron Rev.
