Seminal vesicle calculus after transurethral resection of ejaculatory duct.

We report a case of symptomatic seminal vesicle calculus following transurethral resection of ejaculatory duct. A 37-year-old male, who had previously undergone transurethral resection of ejaculatory duct, presented with perineal discomfort and graveluria. Computed tomography revealed a calculus situated within a dilated left seminal vesicle. The patient was treated with cystoscopy and litholapaxy of the seminal vesicle calculus. Although rare, our case demonstrates that seminal vesicle calculi formation can occur following treatment of ejaculatory duct obstruction, possibly secondary to urinary reflux and stasis.
