title: Stone formation in prostatic urethra after potassium-titanyl-phosphate laser ablation of the prostate for benign prostatic hyperplasia.
abstract: We report three cases of stone formation at the prostatic urethra after 80 W potassium-titanyl-phosphate laser ablation of the prostate for benign prostatic hyperplasia. These complications occurred several months after the procedure. The diagnosis was made by ultrasonography, plain radiography of the kidneys, ureters, and bladder, and cystoscopy in patients who were being evaluated after presenting with irritative voiding symptoms. The patients were treated by cystolithotripsy and resection of the calcified prostatic tissue.
