Persistent urethritis associated with staghorn calculus of the kidney.

Urethritis associated with urinary calculi is of rare occurrence. Harkness (1950) described cases of urethritis secondary to stones in the urethra, bladder, prostate and Cowper's glands. He also gave the history of a patient who developed acute non-specific urethritis, which was cured without active treatment when a renal stone was passed spontaneously after an attackofureteric colic. Since then occasional cases of urethritis and stones in the renal tract have been reported in the literature and authors have considered it worth while to report single cases because the association has been considered to be unusual.
