Long-term outcome of laparoscopic pyeloplasty: multicentric comparative study of techniques and accesses.

Purpose: The aim of the present study was to analyze long-term follow up (18-108 months) of different techniques and routes for laparoscopic repair of uretero-pelvic junction obstruction comparing efficacy and results.

Materials And Methods: A retrospective analyses of 133 laparoscopic pyeloplasties in 132 patients (mean age 35 years) between August 1995 and November 2008 was performed. Transperitoneal route was performed in 114 patients, and retroperitoneal route was performed in 19 patients.

Transperitoneal laparoscopic pyeloplasty: Brazilian initial experience with 55 cases.

Purpose: To evaluate prospectively the results obtained in 55 patients undergoing laparoscopic pyeloplasty through transperitoneal access.

Materials And Methods: From January 2005 to July 2009, fifty-five patients between 13 and 64 years old, were treated for ureteropelvic junction (UPJ) stenosis via a transperitoneal laparoscopy. All patients had clinical symptoms of high urinary obstruction and hydronephrosis confirmed by imaging methods.

Renal epitelial neoplasia associated with Kimura disease.

Objective: To present a case of Kimura disease associated with kidney epithelial neoplasia. Kimura disease is a rare inflammatory disease, which usually presents with enlarged lymph nodes and masses in the head and neck regions. The differential diagnosis should include lymphomas, reaction lymphadenopathy to drugs or parasites.

[Laparoscopic adrenalectomy: a prospective study comparing transperitoneal and retroperitoneal approaches].

Objectives: A prospective protocol was used to compare transperitoneal and retroperitoneal laparoscopic access for treatment of adrenal lesions.

Methods: Forty patients (19 male and 21 female) were submitted to laparoscopic adrenalectomy. Patients were operated by two surgeons.

Preliminary experience with extraperitoneal endoscopic radical prostatectomy through duplication of the open technique.

Objective: To describe surgical and functional results with extraperitoneal laparoscopic radical prostatectomy with duplication of the open technique, from the experience obtained in the treatment of 28 initial cases.

Materials And Methods: In a 36-month period, we prospectively analyzed 28 patients diagnosed with localized prostate cancer undergoing extraperitoneal laparoscopic radical prostatectomy.

Results: Mean surgical time was 280 min, with mean blood loss of 320 mL.
