Primary Obstructive Megaureter: Endourological Treatment
Most patients with primary obstructive megaureter (POM) only need conservative management since functional obstruction resolves spontaneously during the first months of life without renal function impairment or appearance of symptoms . Surgical treatment is then reserved for those cases that develop progressive hydro-ureteronephrosis with urinary tract infections (UTI) and/or renal loss of function. However, its management and surgical options remain controversial. Ureteral reimplantation with or without ureteral tapering has been considered the gold-standard procedure for these patients, but in small infants, reimplantation of a huge ureter is challenging and leads to potential complications .
