Stented versus nonstented transverse colon conduits: a comparative report.
Postoperative urinary tract complications were evaluated in 75 women who underwent urinary diversion with formation of a transverse colon conduit after radiation for gynecologic cancer. Urinary stents were placed at the ureterocolonic junction in 37 women, while no stents were used in 38 women. Leaks or fistulae developed in 18% of the nonstented group but in only 3% of the stented group (P less than 0.05). Ureteral strictures developed in 18% of the nonstented but in only 8% of the stented group. Pyelonephritis developed in 13% of the nonstented and in 8% of the stented patients. Overall, urinary tract complications developed in 50% of the nonstented and in 16% of the stented group (P less than 0.01). Leaks or strictures developed in 11% of the 75 renal units in the nonstented group but in only 1% of the 72 renal units in the stented group (P less than 0.02). Postoperative leaks or fistulae were associated with further serious complications. Results indicate a significant advantage in employing stents at the ureterocolonic junction in the formation of a transverse colon conduit.
