RESUMO
AIM: The incidence of urologic complications after renal transplantation has been reported to be between 2.5% and 27%. The aim of this study was to evaluate urologic complications of and their surgical treatment in our series of renal transplantations. MATERIALS AND METHODS: We retrospectively evaluated urologic complications among 395 renal transplant recipients in our institute. RESULTS: The urologic complications were ureteral leakage (n = 8), stricture of ureteral anastomosis (n = 3), hydronephrosis secondary to stone (n = 2) and bladder outlet obstruction (n = 2), recurrent urinary infection because of vesicoureteral reflux to native kidney (n = 2), renal tumor in native kidney (n = 1), hydroceles (n = 3), technical complications (n = 2), and clot retention (n = 1). CONCLUSION: Major urologic complications following renal transplantation are ureteral leakage and stricture resulting from disrupture of the distal ureteral blood supply during the donor operation. Extravesical ureteroneocystostomy over a JJ stent seems feasible to minimize urologic complication. Early diagnosis and endourologic techniques are the mainstays of treatment.
