[Uretero-vescical anastomosis during kidney transplantation. Preliminary results of two surgical techniques].

AIM
The most frequent urologic complications after renal transplantation involve the uretero-vescical anastomosis (leakage, stenosis, and reflux), with a frequency of 1% to 30% in different series.


METHODS
We present our results in a prospective randomized trial performed from October 2004 to September 2005, in a cohort of 36 patients, who underwent renal transplantation from cadaveric donor at our institution. A uretero-vescical anastomosis according to Lich-Gregoir was used in 18 cases (group A), whereas an anastomosis according to Knechtle was performed in other 18 patients (group B), respectively. The groups were comparable for donors and recipients characteristics. The mean donor age was 46.3 years vs 44.9 years, and the mean duration of cold ischemia was 1 086+/-296 min vs 1 100+/-381 min for group A and for group B respectively. The mean recipient age was 47.5 years vs 46.1 for group A and group B, respectively.


RESULTS
No differences were evidenced between the two uretero-vescical anastomosis in term of surgical complications, infections or patient and graft survival at one year of follow-up. Stenosis and leakage involved 2 patients for each group respectively. Numbers of infections, days of antibiotic therapy were similar between the two groups.


CONCLUSION
Our early experience does not evidence differences between the two types of uretero-vescical anastomosis.
