Argon laser-assisted vasovasostomy.

Laser-assisted vasovasostomy recently has become a popular procedure in the United States. Only the microsurgical carbon dioxide laser is approved by the Food and Drug Administration for vasovasostomies. Using the HGM argon laser, the procedure was performed on 3 laboratory dogs with a patency rate of 100 percent (6/6) and anastomotic leak 17 percent (1/6). This procedure requires little microsurgical expertise, can be performed without the use of a microscope, and does not require a perfectly dry field. The argon laser is a superior technique to previously described laser-assisted vasovasostomies and further clinical correlation is recommended.

Laparoscopic ureterolithotomy.

We describe the successful laparoscopic removal of a distal ureteral cystine stone not amenable to ureteroscopic or medical therapy. This approach offers an alternative to open ureterolithotomy in patients when less invasive measures fail.

Extraperitoneal endoscopic pelvic lymph node dissection vs. laparoscopic lymph node dissection in the staging of prostatic and bladder carcinoma.

Eighteen patients undergoing laparoscopic pelvic lymphadenectomy were compared with eighteen patients undergoing lymph node dissection performed via a totally extraperitoneal approach called extraperitoneal endoscopic pelvic lymph node dissection. Operative time, nodal yield, and hospital stays were essentially the same in both groups. However, the laparoscopic approach had a greater incidence of morbidity, leading the authors to adopt a totally extra-peritoneal endoscopic approach to pelvic lymph node dissection. Advantages of using an extraperitoneal approach are presented.

Extraperitoneal endoscopic pelvic lymph node dissection.

Laparoscopic pelvic lymphadenectomy has been found to be efficacious in the staging of genitourinary cancers. Technological advances in endoscopic instrumentation have allowed an extraperitoneal approach to be performed. Presented are two patients who underwent an extraperitoneal endoscopic lymph node dissection as a staging procedure for prostatic carcinoma. Technical aspects of the procedure and advantages relative to the laparoscopic intraperitoneal approach are discussed.
