Modified transurethral technique for the management of distal ureter during laparoscopic assisted nephroureterectomy.

Introduction: Laparoscopic assisted nephroureterectomy is a well established technique for managing the upper urinary tract urothelial cancer. However, management of the distal ureter remains a controversial issue. We describe a modified method of cystoscopic loop ligation and detachment of the distal ureter.

Does obesity influence the operative course or complications of robot-assisted laparoscopic prostatectomy.

Objective: To determine if obesity is associated with prolonged surgery or more complications during and after surgery in patients undergoing robot-assisted laparoscopic prostatectomy (RALP).

Patients And Methods: Between December 2003 and September 2005 data were collected prospectively for all patients undergoing RALP. Obesity was defined as a body mass index of > or = 30 kg/m2.

Epididymal obstruction results in isolated sperm heads in post-vasectomy rats.

The aim of this study was to determine if, following vasectomy, epididymal obstruction resulted in changes in vasal stump fluid using a rat vasectomy model. One hundred and twenty-two mature male rats underwent bilateral surgical vasectomy and subsequent unilateral epididymal obstruction. Animals were randomly assigned to one of the five cohorts, which determined the time to kill and vasal fluid assessment.

Laparoscopic and open surgical nephrectomy for xanthogranulomatous pyelonephritis.

Background And Purpose: Xanthogranulomatous pyelonephritis (XGP) is a severe, chronic renal-parenchymal infection. Nephrectomy is the treatment of choice. Because of the renal and perirenal inflammatory changes that commonly accompany XGP, the laparoscopic approach is difficult.

Intraoperative local anesthesia decreases postoperative parenteral opioid requirements for transperitoneal laparoscopic renal and adrenal surgery: a randomized, double-blind, placebo controlled investigation.

Purpose: To determine if local anesthesia decreases discomfort following laparoscopic upper retroperitoneal surgery, we performed a randomized, double-blind, placebo controlled study in which the port sites and hand assist incision were infiltrated with bupivacaine or placebo prior to surgery.

Materials And Methods: A total of 72 patients undergoing transperitoneal laparoscopic renal or adrenal surgery were randomly assigned to the treatment (0.5% bupivacaine) or placebo (0.

Helical computed tomography for identification of crossing vessels in ureteropelvic junction obstruction-comparison with operative findings.

Objectives: To evaluate the use of contrast-enhanced helical computed tomography (HCT) scanning with three-dimensional reconstructions as a possible identifier of crossing vessels in ureteropelvic junction (UPJ) obstruction. Endoscopic treatment of UPJ obstruction has a success rate that approaches 90%. These results drop to 40% in the presence of crossing vessels.
