Abstract
Background:
Complete ureteral duplication is uncommon and occasionally associated with ureteral stone obstruction. Even rarer is ectopic insertion of a ureter into the urethra.
Case Presentation:
We describe a case of a 75-year-old man with a history of robot-assisted laparoscopic prostatectomy and complete unilateral duplicated collecting system with a ureteral stone obstructing an ectopic ureter inserting into the urethra. The stone was effectively treated using ureteroscopy with laser lithotripsy.
Conclusion:
Ectopic ureters can be located in any of the Wolffian duct structures, and can perhaps be relocated iatrogenically secondary to bladder neck reconstruction during a prostatectomy. This should be kept in mind when performing ureteroscopy on this patient population.
