OBJECTIVE: To report a series of children with duplicated collecting system (DCS) and associated problems.

MATERIAL and METHODS: The data of patients with DCS between 1996 and 2011 was reviewed retrospectively.

RESULTS: DCS was reported in 59 (M/F:18/41) patients. Mean age at diagnosis was 81.5±41.3 (3- 159) months, mean follow-up duration was 32.2±29.1 (3-130) months. Presenting symptoms were urinary tract infection in 33, nocturnal enuresis in three, diurnal enuresis in two, kidney stones in three and miscellaneous in the rest of the patients. The diagnostic modalities were magnetic resonance urography in three, voiding cystourography in fi ve and intravenous pyelography in the rest. Twentyfour (41%) had right-sided, 24 (41%) had left-sided and 11 (18%) had bilateral DCS in a total of 70 renal units. Insertion of ureters into the bladder could be demonstrated in 33 units (20 incomplete, 13 complete). Vesicoureteral refl ux was found in 16, and ureterocele was found in four renal units. There was refl ux to both moieties in two patients. Surgical interventions included partial nephrectomy in two, ureteroureterostomy in one and anti-refl ux surgery in three of the patients. One patient had Noonan Syndrome and another had atrial septal defect.

CONCLUSION: This series was reported to emphasize the clinical and anatomical problems associated with DCS.
