- Urinary diversion in gynecology is performed primarily in conjunction with cancer surgery, but at times, it is required for women with intractable urinary fistulas or other urologic disorders. After 1950, ileal conduits replaced ureterosigmoidostomies as the most widely used form of urinary diversion. Transverse colon conduits have gained popularity because these nonirradiated bowel segments offer less risk for postoperative urinary leaks and small bowel complications associated with bowel and ureteral anastomoses. In 1978, Kock et al described the use of detubularized segments of ileum and the intussuscepted nipple valves to create a continent pouch that is still advocated by urologists in some centers. Ileocolonic continent pouches, originally suggested in 1908, have received considerable attention in the past 10 to 15 years because of ease of construction, lower revision rates, and higher continence rates compared with the Kock ileal pouches. At the Division of Gynecologic Oncology at the University of Miami, the authors have been using the Miami pouch as the preferred form of continent urinary diversion since 1988, with acceptable results. Women who need urinary diversion can be offered at least two major choices: (1) the traditional bowel (ileum or colon) conduit, which requires an external ostomy appliance, or (2) a continent pouch, such as the Miami ileocolonic reservoir. In choosing between non-continent and continent conduits, the patients must be made aware that the continent pouches are available in only a few centers in the United States and carry a slightly higher risk for complications because of the relatively higher complexity. Nonetheless, data strongly suggest that most of these complications can be managed noninvasively and that these patients retain a closer to normal quality of life. The age, disease status, and general health of the woman and the likelihood of her long-term survival after diversion weigh heavily in the final decision.
