Adult bilateral non-obstructing orthotopic ureteroceles with multiple calculi: endoscopic management with review of literature.

We describe and report two cases of bilateral symptomatic ureterocele with calculi in two young adult women. They were successfully managed endoscopically by a transverse meatotomy and stone extraction done bilaterally in a single operative session. The 6th month postoperative voiding cystourethrogram showed no reflux. The literature regarding the incidence, occurrence, diagnosis and management of this uncommon condition in adults has been reviewed and discussed.
