Supplementary Material for: Bladder Stone Incarceration in Posterior Urethral Valve Leading to Urinary Retention: a case report

Acute urinary retention can be caused by a combination of posterior urethral valves and bladder stones. Here, we introduce a case of acute urinary retention caused by stone blocking the posterior urethral valve. The patient had intermittent urinary retention for more than 1 month. CT scan showed a bladder stone in the posterior urethra. Upon cystoscopy, it was found that intracorporeal litho trisy for calculation with fullness of the PUV was performed using holmium: YAG laser. The patient had the catheter removed and was discharged smoothly on the 5th day after surgery.
