RESUMO
OBJECTIVES: Simple renal cysts (SRC) are usually asymptomatic and do not require any kind of treatment. Laparoscopy is a reasonable minimally invasive surgical option for symptomatic cysts. Herein, we present the results of the laparoscopic technique for the treatment of symptomatic renal cysts performed in our institution. METHODS: Between November 1992 and May 2006, 41 patients with symptomatic renal cysts were laparoscopically treated. The surgical techniques employed were transperitoneal and retroperitoneal. Demographic and surgical data was prospectively collected and analysis retrospectively performed. RESULTS: 41 patients were treated for symptomatic renal cysts in a fourteen year period. 23 (56%) women and 18 (44%) men, with a median age of 54 years. (Range 27-74 years.). All patients in the series were symptomatic. Pain was the most frequent symptom. Median cyst size was 10 cm. (range 5-16 cm.). Transperitoneal approach was performed in 24 patients (58%) and retroperitoneal in 17(42%). No differences were verified between these approaches. 16 lesions were located at the left renal unit, 24 in the right renal unit (54%) and one case presented bilateral lesions (3%). Median operative time was 52 min. (range 20-150 min.), median hospital stay was 42 hours (range 12-96 h.). 39 cysts (95.2%) were classified as Bosniak's type I lesions, 2 lesions (4.8%) were type II based on Bosniak's description. Final pathology confirmed every lesion as a simple renal cyst. There was only one relapse in the series. The latter was treated percutaneously. CONCLUSIONS: Laparoscopy is a feasible, safe and advantageous surgical therapeutic option for symptomatic renal cysts.

OBJECTIVE: Leiomyoma is a benign lesion which represents 0.04-0.5% of bladder tumors. It is more common in females and its peak incidence is between 4th and 5th decades. Surgery is the treatment of choice and adequate results have been previously reported. METHODS: 38 years old male patient who consulted for chronic pelvic pain syndrome. CT scan showed a 2 cm diameter exophitic lesion at the anterior left lateral bladder wall, which protruded into the perivesical fat. We performed a laparoscopic partial cistectomy locating the tumor and resecting it with simultaneous cystoscopic control, obtaining negative margins. The operative time was 70 minutes with an intraoperative blood loss of 50 ml. Postoperative period was uneventful. Final pathology reported: Bladder wall leiomyoma, without mitosis or atypia. Immunohistochemistry was positive for Actine and Vimentine stablishing diagnosis. Cd 1 17 (c-kit) was negative and ruled out a Gastrointestinal Stromal Tumor. CONCLUSIONS: Leiomyoma is bladder's most common benign non epithelial tumor. It represents 35-46% of these lesions with a 2:5 male/female ratio. It origins from the smooth muscle bundles and at the urinary tract the most common localizations are kidney and bladder. Clinical presentation depends on tumor size and localization. Ultrasound is the most useful diagnostic tool and the pathological diagnosis is mandatory. Surgery is the treatment of choice and technique depends on tumor size and localization. The laparoscopic approach seems to be an effective alternative in this group of tumors. Prognosis is good and recurrence is rare.

OBJECTIVES: Partial cystectomy is a recognized bladder sparing surgical technique. Patient selection is essential in order to optimize long term results. We present our initial experience with laparoscopic partial cystectomy performed in a selected group of patients that includes both benign and malignant lesions. METHODS: Nine patients were surgically treated with laparoscopic partial cystectomy between July 2002 and September 2006 in our institution. Partial cystectomy was indicated for the treatment of a foreign body, endometriosis, urachal adenocarcinoma, trancisional cell carcinoma, acquired lesions of urachus and extravesical tumor. Analyzed surgical variables were operative time, conversion rate, blood loss, hospital stay and catheterization period. RESULTS: Nine patients with bladder lesions were laparoscopically operated for partial cystectomy. Transperitoneal technique was employed and no conversion to open surgery was performed. Median operative time was 77.77 min (range 30-120 min.). No patient received any transfusion. No intraoperative lesions were verified. Median hospital stay was 4.22 days (range 3-5 d.), median catheterization period was 7 days (range 5-10 d.). CONCLUSIONS: Laparoscopic partial cystectomy is a doable surgical procedure. It is a useful technique for both benign and malignant bladder disease. In TCC and urachal carcinoma oncological safety prevails. Patient selection is essential for this procedure.
