RESUMO
Background: urinary tract infection [UTI] is the most common infectious complication following renal transplantation. The purposes of this study were to determine the causative agents of UTIs and the survival rate among renal transplant recipients
Material and method: we evaluated 214 recipients who underwent transplantation in terms of their urine culture at first month and kidney function at the first year after kidney transplantation during the period 1995 to 2005 at shohada hospital. All patients received prophylaxis with co-trimaxazole. Medical records of the patients were reviewed retrospectively
Result: from all patients' urine cultures, urinary tract infections were confirmed among 96[44.9%] of them. Bacterial infections were the most frequent etiologies: gram-negative bacilli in 67 [69.7%], gram-positive cocci in 23 [24%], and six fungal [6.3%] infections. In fact, the causative microorganisms were E.coli as the principal isolated agent in 42 cases [43.8%]. The survival rate of the graft at the end of the study period was 92.2%, and the survival rate of the transplant recipient's was94.8%
Conclusion: the incidence of UTI in transplant patients who received antibiotic prophylaxis was high. E.coli was the main agent isolated. UTI, the most frequent post transplantation infection, showed a good prognosis
