Abstract

Urological complications after renal transplantation (urinary fistula, urinary tract dilatation) are frequently associated with urinary tract infections (UTI). We tried to analyse whether urinary tract infection was one of the factors which participated in the lower allograft survival rates and reduced allograft function in urologically complicated (UC) patients. We observed 77 patients after renal transplantation (Tx) of whom 42 had urinary fistula, 32 had urinary tract dilatation a 3 had both complications (1/1992-XII/l996). 100 patients without urological complications represented a control group (N). Obtained data was statististically evaluated using t-test, x2-test, correlation analysis. Graft and patient survival rates were assessed using the Kaplan-Meier method. We have found that UC patients after Tx had a worse renal function compared with patients not suffering from this complication. Using Kaplan-Meier methods we have found that graft survival rate in patients with UC is significantly lower than that in the control group (5-year graft survival 0.6 vs 0.82, p
