OBJECTIVE: To evaluate the outcome of anti-reflux revision surgery in patients diagnosed with at least a grade 3 reflux at voiding cysto-urethrography in patients with recurrent urinary tract infection (UTI) after renal transplantation. PATIENTS AND METHODS: We identified 60 patients with a diagnosis of recurrent febrile UTI and post-transplantation vesico-ureteric reflux (VUR) who underwent open surgical correction of reflux. Patient characteristics, including the aetiology of end-stage renal disease, age, time to VUR correction, type of VUR correction, serum creatinine levels, and number of UTIs before and after correction were documented. RESULTS: The median (range) age of the patients was 31.5 (9-65) years. A total of 30 patients underwent uretero-ureterostomy or pyelo-ureterostomy and 30 underwent extravesical or intravesical ureteric reimplantation. The median (range) creatinine levels before and after correction were 1.5 (0.8-4.5) mg/dL and 1.3 (0.7-4.5) mg/dL (P<0.05), respectively. The median (range) number of UTI episodes reported before the correction surgery was 4 (3-12), whereas number of UTI episodes after the surgery was 1 (0-12), the difference being significant (P<0.05). CONCLUSIONS: Open surgical correction of post-transplant VUR is an effective and safe method of decreasing UTI episodes and stopping reflux. Surgical correction of reflux may prolong the life of the renal graft.
