title: Comparative study of one-stitch versus Lich-Gregoir ureterovesical implantation for kidney transplants.
abstract: OBJECTIVE
  To compare the outcomes of standard Lich-Gregoir technique and a modified one-stitch technique of ureteroneocystostomy in renal transplantation.
  
  
  METHODS
  Data from 645 transplant recipients by two different ureteroneocystostomy techniques were retrospectively reviewed at the first Affiliated Hospital, Medical College of Xi'an Jiaotong University, between January 2002 and December 2007.
  
  
  RESULTS
  There were 418 recipients in the Lich-Gregoir group and 227 in new one-stitch group. The overall ureteral complication rate for new one-stitch technique was 19.8 % (n = 45) as opposed to 15.79 % (n = 66) for the Lich-Gregoir technique. No significantly different rate of ureteral complications occurred in two groups (P > 0.05). In comparison, there was a higher proportion of hematuria at the limit of statistical significance in new one-stitch group (P < 0.05). Average operative time for the modified one-stitch and Lich-Gregoir techniques was 8.8 ± 1.4 and 21.9 ± 6.1 min, respectively (P < 0.05). Urinary tract infections, delayed graft function and rejection rates were not significantly different between the two groups (P > 0.05).
  
  
  CONCLUSIONS
  Although the modified one-stitch technique may predispose patients to higher rates of hematuria, it has no significant difference in ureteral complications compared with the Lich-Gregoir group. Based on this large series and data analyses, we believe that this new technique will become one of our multiple choices in our setting.
