Stenting of the extravesical ureteroneocystostomy in renal transplantation is controversial. This study is a metaanalysis of 49 published studies over 30 years time in which the extravesical technique was used. Stented and nonstented anastomoses were compared. One-hundred six articles published between 1973 and 2002 were reviewed and 49 met criteria for inclusion. Articles were required to list original, numeric, previously unpublished data and to report or to describe the use of an extravesical ureteroneocystostomy, with or without stent. Data were analyzed within separate groups, (1) randomized, controlled trials and (2) case series. Data were included from five randomized, controlled trials and 44 case series. In the controlled trials group, there were urologic complications in 6 of 407 stented (1.5%), and 35 of 389 nonstented subjects (9.0%) (p < 0.0001, OR 0.24, 95% CI 0.10-0.57). In the case-series group, there were urologic complications in 137 of 4245 stented (3.2%) and 433 of 9077 nonstented subjects (4.8%) (p = 0.007, OR 0.58, 95% CI 0.39-0.86). Renal transplants with stented extravesical ureteroneocystostomy have a significantly lower urologic complication rate than those with nonstented anastomoses. All five randomized, controlled trials individually found stented anastomoses to have a lower complication rate and this was confirmed by metaanalysis of these trials and of case-series data.
