COMPLICATIONS OF URETEROVESICAL ANASTOMOSIS IN KIDNEY-TRANSPLANT PATIENTS - THE MINNESOTA EXPERIENCE

We reviewed urologic complications of 1183 consecutive primary or seco ndary renal transplants performed with bladder anastomoses at the Univ ersity of Minnesota Hospital between 1985 and 1993. The Politano-Leadb etter (PL) technique of ureteroneocystostomy was used in 410 patients; the multistitch (MS) extravesical technique modified from the methods of Witzel, Sampson, and Lich in 295; and the extravesical single-stit ch (SS) technique in 478. Urologic complications occurred in 81 patien ts (6.8%). Of these complications, 68 (5.7%) were early (<4 months) an d 13 (1.1%) late; 32 (7.8%) were after PL, 17 (5.8%) after MS, and 32 (6.7%) after SS. A total of 13 patients had an anastomotic leak, 7 (1. 7%) after PL, 4 (1.4%) after MS, and 2 (0.0004%) after SS; 49 patients had a ureterovesical obstruction, 16 (4.0%) after PL, 12 (4.0%) after MS, and 21 (4.2%) after SS; 5 patients had a ureteropelvic obstructio n, 2 (0.5%) after PL, 2 (0.7%) after MS, and 1 (0.2%) after SS; and 14 patients had hematuria, 7 (1.7%) after PL, 1 (0.34%) after MS, and 6 (1.3%) after SS. Of the 81 patients with urologic complications, one ( 1%) resolved spontaneously; 30 (37%) were treated with temporary percu taneous nephrostomy, 17 (21%) with dilatation and stent; the 14 (17.3% ) with hematuria were treated via cystoscopy; 19 (23%) required reoper ation. Only 2 (2.5%) patients lost their graft. For both cadaver and l iving donor recipients, there was no difference between techniques for early and late complications of leakage, stricture, and hematuria. Ea ch technique has certain advantages and each should be in every surgeo n's repertoire.
