PURPOSE: We compared the incidence of urological and anastomotic complications, and the duration of ureteral reimplantation for the Taguchi and Lich-Gregoir techniques. MATERIALS AND METHODS: We recorded all urological and anastomotic complications that developed from the date of transplantation through December 31, 2001. The cutoff date for transplantation was August 30, 2000. The urological complications evaluated included complicated hematuria, urinary fistula, ureteral stenosis, symptomatic vesicoureteral reflux and operative time. The chi-square test was done to compare the proportion of complications in the groups and the Mann Whitney test was used to compare the duration of ureteral reimplantation. RESULTS: Of the 575 transplants evaluated 416 and 159 were performed via the Lich-Gregoir and Taguchi techniques, respectively. The incidence of anastomotic complications was 10.7%. Complications in the Lich-Gregoir group included fistula in 4.7% of cases, stenosis in 4.1%, symptomatic vesicoureteral reflux in 1.9% and complicated hematuria in 0.5%. Complications in the Taguchi group included urinary fistula in 6.3% of cases, stenosis in 2.5% and complicated hematuria in 2.5%. Symptomatic reflux was not observed in this group. There was a higher proportion of hematuria at the limit of statistical significance in the Taguchi group (p = 0.05). There were a higher number of urological complications in transplants from live donors in the Lich-Gregoir group (p = 0.01), mostly involving fistula (p = 0.05). There were no significant differences in the groups in overall complications. Average operative time for the Taguchi and Lich-Gregoir techniques was 14.2 and 29 minutes, respectively. This difference was significant (p = 0.02). CONCLUSIONS: In the sample studied Taguchi ureterocystoneostomy proved to be a more rapid method without increasing the incidence of urological or anastomotic complications. There were no cases of symptomatic reflux in the Taguchi group and select fistula cases could be managed conservatively. The Lich-Gregoir cohort was at greater risk for the urological complications of live donor transplantation. The Taguchi method has become the ureterovesical reimplantation technique of choice in our setting.
