Holmium laser endourethrotomy and litholapaxy of an occult prostatic utricle calculus.

Prostatic utricle (PU) stones are rare and the surgical treatment of such PU anomalies has proved challenging given their location adjacent to the posterior urethra and proximity to important fertility and continence structures. We report the case of a 58-year-old male with hypospadias, microphallus, and irritative lower urinary tract symptoms (LUTS) found to have a large PU stone. He underwent successful complete endoscopic removal of the stone via transurethral unroofing and holmium laser litholapaxy. We conclude that it is an effective alternative to other surgical techniques once size of the stone and the patient's individual anatomy are considered.
