Abstract
INTRODUCTION: We report a case of megaureter in a functional solitary kidney in which surgery was performed after bladder capacity was increased by home bladder cycling. CASE PRESENTATION: A 6-day-old girl with a left megaureter, a right multicystic dysplastic kidney, and bladder hypoplasia underwent percutaneous left nephrostomy for obstructive renal failure. At 8 months, home bladder cycling was initiated to increase bladder capacity before the planned ureterocystoneostomy. Surgery was performed after bladder capacity increased. The left ureter was compressed by the left umbilical ligament, so ureteral end-to-end anastomosis was performed at 1 year and 4 months. At 2 years and 8 months, cystometry showed age-appropriate bladder capacity and improved bladder compliance. CONCLUSION: To the best of our knowledge, this is the first report of bladder hypoplasia treated by home bladder cycling.
