We sought to explore the incidence, risk factors, clinical presentation, management options, and outcomes of post renal transplant urologic complications. Between June 1986 and December 2005, we performed 348 renal transplantation (Charles Nicolle Hospital Tunisia). Kidney grafts were obtained from 277 living and 71cadaveric donors. The medical records were retrospectively reviewed for urologic complications. Urologic complications were detected in 26 recipients (7%) they had received kidney grafts from 10 living and 16 cadaveric donors. Urologic complications were ureteric strictures in 4, urine leaks in 17, and stone in 5 recipients (ureteral in 1, bladder in 2 and pyelic in 2). In conclusions, post transplantation urologic complications are associated with a good prognosis if diagnosed early and properly treated. Percutaneous transluminal dilatation of ureteric stenosis in renal transplant patients has good initial success, low morbidity, few recurrences, and long-term effectiveness .
