RESUMO
OBJECTIVE: Laparoscopic adenomectomy 150 is a minimally invasive alternative to open surgery in large prostates. Our aim is to discuss our series of 59 patients treated by means of laparoscopic adenomectomy with precise vascular control. MATERIALS AND METHODS: Between June 2003 and June 2006, a total of 59 patients with a mean age of 65.5 years (51 to 82), underwent laparoscopic extraperitoneal adenomectomy. All the patients had a history of lower urinary tract symptoms (LUTS) and benign prostatic hyperplasia (BPH). The mean International Prostate Symptom Score (IPSS) was 20 points (16-22). The information was collected prospectively in a database. The analysis was performed subsequently. RESULTS: All 59 adenomas were completely removed laparoscopically without conversion to open surgery. The mean preoperative prostate volume by ultrasound was 108.5 cc (75-150). The average operating time was 123 minutes (90-180). The mean loss of blood was 415 ml (50-1500) and 4 patients (14.8%) required a blood transfusion. Two (7.4%) of the patients presented perioperative complications. The mean hospital stay and the bladder catheterization time were 3.5 (2-7) and 4.2 (3-7) days respectively. CONCLUSIONS: Laparoscopic extraperitoneal simple prostatectomy is an effective procedure for the treatment of large prostatic adenomas. There seems to be less perioperative morbidity and, in our experience, this technique seems to be feasible and reproducible; however, its learning curve is a complicated matter to deal with.

Angiomyolipoma (AML) is a benign clonal neoplasm that consists of varying amounts of mature adipose tissue, smooth muscle, and thick-walled vessels. Approximately 20% of AMLs are found in patients with tuberous sclerosis syndrome (TS), an autosomal-dominant disorder characterized by mental retardation, epilepsy, and adenoma sebaceous, a distinctive skin lesion. Massive retroperitoneal hemorrhage from AML, also known as Wunderlich's syndrome, has been found in up to 10% of patients and represents the most significant and feared complication. The presence of even a small amount of fat within a renal lesion on CT scan (confirmed by Hounsfield unit's < or = 10) is considered diagnostic of AML. Intervention should be considered for larger tumors, particularly if the patient is symptomatic, taking into account patient age, comorbidities, and other related factors. A nephron-sparing approach, via either partial nephrectomy or selective embolization, is clearly preferred. We present the case of a fifty-nine-year old patient with an angiomyolipoma and massive retroperitoneal hemorrhage with Lenk syndrome.
