Comparative study between two techniques of ureteroneocystostomy: Taguchi and Lich-Gregoir

Objective. The aim of this study was to evaluate the results of renal transplantation comparing 2 techniques of ureteroneocystostomy (Taguchi vs Lich-Gregoir). Patients and Methods. Between October 2002 and December 2005, we performed 277 renal transplant procedures in which we used 1 of these 2 techniques of ureteral implantation (Taguchi or Lich-Gregoir). We evaluated the results as well the rate of urinary complications, dividing the patients into 2 groups. The Taguchi group had 60 patients (21.7%) and the Lich-Gregoir group had 217 (78.3%). The 2 groups were compared according to donor and recipient age and weight. Results. Small differences were observed regarding immediate diuresis, acute rejection, graft survival, patient survival, renal function, or rate of urinary complications. The differences did not achieve statistical significance. Conclusions. Both techniques showed similar results; however, the Taguchi technique is simpler and more rapid. Greater experience is needed to evaluate the long-term results.
