Duplication of the renal pelvis is a common congenital malformation of the urinary system. About one-third of cases are complete unilateral duplication of the renal pelvis, while bilateral duplication is extremely rare. Herein, we described a single case of bilateral renal duplication with double ureteral orifice ectopic vaginal fistula treated with laparoscopy.
A 6-year-old girl suffering from long-term vaginal leakage was admitted on June 10, 2018. She was diagnosed with complete duplication of both kidneys and ureters and ectopic opening of both ureters combined with ureterovaginal fistula. The patient received laparoscopic ectopic ureteral bladder replantation and was followed up for 2 years. No renal function damage and vaginal leakage were found.
Laparoscopic bladder-ureter reimplantation could effectively determine the location and number of ectopic ureters by imaging and cystoscopy.
Core Tip: This paper reported a rare case of bilateral complete duplication of renal pelvis with ectopic bilateral ureteral openings. The diagnosis was confirmed by imaging contrast examination and cystoscopy staining test, and the bilateral ectopic openings were successfully repaired by laparoscopy. This study provided a reference for clinicians to improve the diagnosis and treatment experience of such cases in the future.
