Ureteral Complications of Pediatric Renal Transplantation

Purpose:Ureteral complications following renal transplantation are more common in children than in adults. We identify potential risk factors for ureteral complications in pediatric patients.Materials and Methods:We retrospectively studied a cohort of patients who underwent renal transplantation at Lurie Children's Hospital between 2004 and 2016. We analyzed the associations between patient characteristics, operative factors, graft characteristics and postoperative complications.Results:A total of 224 renal transplantations in 219 patients were identified. Preexisting bladder pathology was present in 25% of cases. Overall rate of ureteral complications was 16%, with symptomatic vesicoureteral reflux being the most common. Ureteral complications were seen significantly more frequently in patients with underlying bladder pathology (26% vs 12%, p = 0.01). Rate of postoperative vesicoureteral reflux in patients with bladder pathology was lower when a urologist performed the reimplantation but the difference w...
