Although transrectal ultrasound-guided biopsies (TRUSB) of the prostate gland are generally considered to be low-risk procedures, a study from Canada reported that there had been a significant increase in the percentage of hospital admissions following TRUSBs between 1996 and 2005 (1.0% to 4.1%).

Background: Various techniques for vascular control have been used during urologic laparoscopic procedures. The importance of optimizing the vessel length and securing reliable vascular control are critical for procedures like laparoscopic donor nephrectomy. We aimed to determine the length of vessel lost by using 4 common techniques of vascular control in a fresh human cadaveric vascular model.

Vascular control during laparoscopic donor nephrectomy (LDN) requires expeditious control of the renal artery and vein while preserving maximum graft vascular length. The vascular stapler with three rows of staples on either side of the division has been widely used, but it loses more vascular length than other methods. In the accompanying video, we illustrate vascular control with the different staplers and locking polymer clips.

Background And Purpose: Laparoscopic partial nephrectomy (LPN) is technically challenging with a steep learning curve, primarily because techniques used to control bleeding on the cut surface of the kidney can be ineffective, inconsistent, or challenging. Hemostatic techniques can include intracorporeal suturing, vascular coagulation (argon-beam coagulator, bipolar cautery, laser), and application of various tissue sealants. There is no uniformity of opinion regarding which hemostatic technique is optimal for this application.

Objectives: Minor intraoperative bleeding during laparoscopy poses a significant challenge to the minimally invasive urologist. We report on our improvement of the previously reported laparoscopic cigarette sponge with absorbable materials.

Methods: The sponge was constructed from a strip of absorbable gelatin sponge wrapped in oxidized regenerated cellulose and secured with absorbable suture.

Objectives: The benefits of laparoscopic surgery with robotic assistance (da Vinci Robotic Surgical System, Intuitive Surgical, Sunnyvale, CA) includes elimination of tremor, motion scaling, 3D laparoscopic vision, and instruments with 7 degrees of freedom. The benefit of robotic assistance could be most pronounced with reconstructive procedures, such as pyeloplasty. We aimed to compare laparoscopic pyeloplasty, with and without robotic assistance, during a surgeon's initial experience to determine whether robotic assistance has distinct advantages over the pure laparoscopic technique.

Background And Purpose: The use of lymphadenectomy in renal-cell carcinoma (RCC) is controversial. Proponents argue that lymphadenectomy improves survival, whereas opponents challenge the procedure on the basis of its morbidity and the variable lymphatic drainage of the kidney. Intraoperative gamma probes have been used to guide resection of radiolabeled sentinel nodes in cancers of the breast, penis, and head and neck and in melanoma.

Objectives: To determine whether the distinct advantages of a catheter-free hypospadias repair can be obtained with a Barcat procedure without an adverse effect on surgical outcome.

Methods: A retrospective review was performed on consecutive patients who had undergone a catheter-free Barcat repair from July 1998 to May 2002. Patient records were examined for information regarding age, meatal location, primary or secondary procedure, operative time, postoperative follow-up, and complications.

Purpose: Experience with simple perineal prostatectomy has not been well described in the recent literature. We describe our operative technique and compare objective demographic, preoperative, intraoperative and postoperative parameters in patients undergoing open prostatectomy for benign prostatic hyperplasia via 3 routes, namely perineal, retropubic, and suprapubic.

Materials And Methods: We retrospectively reviewed all cases of open prostatectomy at Veterans Affairs Medical Center, San Diego between August 2001 and September 2002.

Objectives: To evaluate the prevalence, clinical correlates, and severity of sexual dysfunction in combat veterans with and without post-traumatic stress disorder (PTSD) using a validated instrument for assessing sexual function. The results of recent studies have suggested that combat veterans with PTSD experience a higher rate of sexual dysfunction than do those without PTSD.

Methods: We administered the International Index of Erectile Function (IIEF) and a demographic and health questionnaire to male combat veterans undergoing treatment for PTSD and to age-comparable male combat veterans without PTSD.
