OBJECTIVES: Our goal was to investigate the safety and efficacy of the Boari bladder flap procedure in patients who received either allogeneic or autotransplant of kidneys.
MATERIALS AND METHODS: We retrospectively reviewed the medical records of all patients with either allogeneic or autotransplant of kidneys who also underwent Boari bladder flap procedures between January 2007 and January 2018. Boari bladder flap was preferred in management of ureteral com-plications after allogeneic renal transplant or it was combined with renal autotransplant when ureteral length was not sufficient to allow ureterovesical anastomosis in patients with ureteral injury.
RESULTS: Boari bladder flap procedures were performed in 14 patients who had undergone heterotrophic renal transplant. Nine patients had undergone allogeneic renal transplant, and 5 patients had renal auto-transplant. The mean age of patients was 41.7 ± 13.4 years. The 5 patients with renal autotransplant procedures had simultaneous Boari flap procedures due to ureteral avulsion during retrograde ureter-orenoscopic surgery for urolithiasis. For the entire cohort, mean preoperative and postoperative (at month 1) serum creatinine levels were 1.42 ± 0.71 and 1.13 ± 0.43 mg/dL, respectively. At last visit, the mean creatinine level was 1.94 ± 1.88 mg/dL.
CONCLUSIONS: The Boari bladder flap procedure can be a safe and relevant choice in the management of challenging complications after heterotrophic (either allogeneic or autotransplant) renal transplant, allowing minimally invasive urologic surgery, no need for use of bowel segments, and no potential risk for the contralateral kidney.
