Urinary Tract Infections in Urologically Complicated Patients After theRenal Transplantation

Overview

Background.
Urinary tract infections (UTI) are the most frequent infectious complications after renal transplan-tation (Tx). We tried to analyse whether the urinary tract infection was one of the factors which participated in thelower allograft survival rates and in the reduced allograft function in urologically complicated (UC) patients.Methods and Results. We observed 77 patients after Tx whom 42 had urinary fistula, 32 had urinary tract dilatationa 3 suffered from both complications. They were observed from January 1992 through December 1999. 100 patientswithout urological complications represented a control group (N). Obtained data was statistically evaluated usingt-test, c2-test, correlation analysis. Graft and patient survival rates were assessed using the Kaplan-Meier method.We have found that UC patients after Tx had worse renal function compared with patients not suffering from thiscomplications. Using Kaplan-Meier methods we have found that graft survival rate in patients with UC is significantlylower than that in the control group (5-year graft survival 0.6 vs 0.82, p
