Bilateral single system ectopic ureters opening into vestibule with bladder agenesis.

Almost 80% of ectopic ureters are associated with duplicated system, and 5-17% of ectopic ureters are bilateral. Ectopic ureters usually open into urethra, vestibule and vagina in females and into posterior urethra and seminal vesicles in males. Bilateral single-system ectopic ureter (BSSEU) is a rare entity in urology. BSSEU opening into a vestibule with the absence of urinary bladder is an extremely rare occurrence. We report such a case and briefly discuss its management.
