A Case of Chronic Back Pain: Revealing Complete Ureteral Duplicity in an Adult Woman

Ureteral duplication is a rare congenital anomaly, often diagnosed incidentally, characterized by the presence of two distinct ureters draining a single kidney. This condition can lead to complications such as vesicoureteral reflux or upper pole obstruction, often due to ectopic ureteral insertion or ureterocele. We report the case of a 40-year-old woman presenting with left-sided chronic low-back pain. Imaging studies, including ultrasound and CT urography, revealed bilateral ureteral duplication with significant left ureterohydronephrosis due to dysplasia and ectopic insertion of the upper ureter. Radiological imaging, especially CT urography, is essential for diagnosing ureteral duplication and identifying its complications. Timely imaging and intervention are critical for preserving renal function, with treatment options depending on the extent of renal impairment. These may include partial or total ureteronephrectomy or ureteral reimplantation.
