Conservative management of colon injury following percutaneous renal surgery.

Objectives: Colon injury during percutaneous renal surgery is rare and can result in significant morbidity. Our objective was threefold: (1) to identify risk factors for colon injuries; (2) to optimize prevention of such injuries; and (3) to devise a treatment strategy for optimal management of such colon injuries.

Methods: Between July 1990 and July 1995, all percutaneous renal procedures performed at three kidney stone centers were reviewed (Kaiser Permanente Medical Center, Los Angeles; Hospital of the Good Samaritan, Los Angeles; and University of California at San Francisco).

Endoscopic treatment of pediatric urolithiasis.

Children have been slow to benefit from the improvements in stone therapy. Despite the success of less invasive techniques, open surgery for pediatric urolithiasis is still commonly practiced. The authors' goal was to evaluate the indications, efficacy, and complications of endourologic surgery in the treatment of pediatric urolithiasis.

Endoscopic laser lithotripsy: safe, effective therapy for ureteral calculi.

At our lithotripsy department more than 400 patients with renal or ureteral calculi have been treated with a pulse-dye laser for stone disease. We review our experience during an 11-month period when a total of 223 patients was treated. Of these patients 204 whose ureteral calculi were treated by laser lithotripsy are available for followup.

Treatment of unusual Kock pouch urinary calculi with extracorporeal shock wave lithotripsy.

Since the establishment of extracorporeal shock wave lithotripsy for the treatment of upper urinary tract calculi, further potential applications have been explored. We report the successful use of extracorporeal shock wave lithotripsy for the treatment of obstructive calculi on staples within the afferent nipple of a Kock pouch ureteroileal urinary diversion.
