Key Points

To highlight a rare case of posterior urethral valve leading to urinary obstruction and stone formation in an adult.
Documented a 21-year-old male with lower urinary tract symptoms for 5 years.
Performed an open cystolithotomy to remove a large posterior urethral stone.
Conducted urethrogram and cystoscopy to confirm the presence of posterior urethral valve.
Applied holmium laser ablation to treat the valve and measure post-ablation uroflowmetry.
Removal of the 35 mm stone alleviated obstruction.
Cystoscopy confirmed the diagnosis of posterior urethral valve.
Significant improvement in urinary flow rate following ablation.

Abstract

Posterior urethral valve (PUV) rarely causes adult lower urinary tract obstruction and is rarely linked to posterior urethral calculi. A 21-year-old male with 5-year history of (LUTS) had a 19×22×39 mm posterior urethral stone removed via open cystolithotomy (35 mm stone). Persistent poor flow led to RUG/MCUG showing urethral dilatation and cystoscopy confirming PUV, ablated with holmium laser. Post-ablation uroflowmetry improved markedly. Adult PUV with impacted calculus is extremely rare, mimicking isolated stone disease. High suspicion for PUV in young males with posterior calculi and post-removal LUTS is vital; cystoscopy and voiding studies ensure accurate diagnosis and management.
