We studied the incidence and the risk factors predisposing to post transplantation urinary tract infection (UTI) and the association with use of different immunosuppressive regimens. We performed a retrospective analysis of 152 recipients of renal transplantation over a period of two years. Seventy one (46.71%) patients had culture positive UTI, Escherichia coli (45.1%) being the commonest. Thirty four (22.39%) patients had acute rejection and 14.4% of those had suffered UTI in the early post transplant period. Immunosuppression included induction with various antibodies and maintenance on antirejection medications. Trimethoprim-sulphamethoxazole was given as prophylaxis throughout the period. The UTI was treated according to microbiological sensitivity. 2.8% died due to urosepsis. In our retrospective analysis renal transplant recipients under the age of 45, female gender and diabetics suffered more UTI. Combination therapy with micro-emulsion form of cyclosporine A, prednisolone and azathioprine developed more UTI (P= 0.0418).
