[Urologic complications in renal transplantation. Study of 250 cases].
OBJECTIVE
The aim of this study is value the incidence of urological complications (fistulae and estenosis) in our serie of renal transplant, to analyze the variables that can influence in their appearance and the treatments used. Likewise, to value the follow-up of theses patients and the survival of the renal graft and of the patient.


METHODS
250 renal transplants are carried out between july of 1985 and october of 1998. The relationship among the variables you makes by means of the test chi 2 of Pearson and the test of Fisher; the contrasts of stockings with the t of Student; the survival of the organ and of the patient, by means of the analysis of curved of survival according to the method of Kaplan and Meier; and the comparison among curved of survival was carried out with the test of Cloth and Cox.


RESULTS
Of the 250 transplants, 46 patients suffered for complications, 29 urinary fistulae (11.6%) and 21 estenosis (8.4%). The most frequent localization in both complications was the union uretero-vesical. The presence of urinary fistulae didn't influence negatively in a significant way nor over the survival of the implant (p < 0.211), neither over the patient's survival. The estenosis appearance was related in a significant way with the donor's age (p < 0.02). The estenosis presence was not related in a significant way neither with the survival of the implant neither with that of the receiver.


CONCLUSIONS
The incidence of urological complications was of 18.4% (11.6% estenosis and 8.4% fistulae). The most frequent localization was the union uretero-vesical. The presence of estenosis correlated with the increase of the age of the donors. The technique of reimplante ureteral didn't influence in the results in a significant way. We don't find any relationship between the appearance of urological complications and the patient's survival.
