Minimal Invasive Management for Bladder Stone and Urethral Stone followed by Urethral Diverticulum: A Rare Case Report

A BSTRACT Urethral stones in men can cause dysuria and urinary retention. They may originate from the migration of kidney or bladder stones or from primary stones in the urethral diverticulum (UD). This study presents a case of acute urinary retention in an elderly man, treated with minimally invasive methods. Retrograde urethrography revealed membranous urethral stenosis with two large stones, and urethroscopy identified two large stones in the posterior UD, along with a giant bladder stone. Ultrasonic lithotripsy and pneumatic lithotripsy, combined with standard flow resection sheath, were used to fragment the two giant stones in the UD. Follow-up showed that the patient was able to micturate spontaneously without incontinence. In conclusion, transurethral lithotripsy is an effective, safe, and minimally invasive procedure for treating multiple large stones in the male posterior UD and giant bladder stones.
