Abstract:
From July 1, 2006 to June 30, 2007, 151 patients with complex pelvic pathology underwent placement of lighted ureteral stents by a general surgeon or gynecologist. None of the patients who underwent preprocedure ureteral stent placement had a ureteral injury. The procedures included laparoscopic colorectal surgery (45 pts), hysterectomy/GYN (49 pts), or pelvic adhesions (57 pts). The average time from placement of the stents to start of the operation was 5 minutes (range, 2 to 15). In 6 patients, the stents could not be placed, and all had ureteral pathology that was NOT noted preoperatively. Two patients had ureter injuries at our hospital and did not have ureteral stents placed during the same time period. The cost of the stents is $205. OR time past the first half hour ranges from $560 to $716 for each additional half hour. The time saved from the lighted identification of the ureters versus visual nonstent identification is from zero minutes to 45 minutes. This is an extremely useful procedure that can theoretically reduce ureter injury to zero. In an era in which insurance will not pay for complications related to the original operation and high litigation costs, this procedure should be the standard of care for safely performing complex pelvic surgery.

Introduction to Urinary System
The kidneys are bean-shaped organs located in the retroperitoneal space, on either side of the vertebral column, between the T12 and L3 vertebrae. They are partially protected by the rib cage and surrounded by perirenal fat, which provides cushioning. They are responsible for urine formation and play critical roles in regulating blood pressure, electrolyte levels, and hormone production. The ureters...
Urethra
The anatomy of the urethra differs between males and females. In females, the urethra is short, measuring about 3–4 cm in length, and opens anterior to the vaginal opening. In males, the urethra is longer and passes through the penis, serving dual purposes: expelling urine and ejaculating semen. The male urethra is...
