Potassium-titanyl-phosphate laser vaporization of the prostate: a case series of an unusual complication.
Abstract   Despite its increasing use in the management of symptomatic benign prostatic hyperplasia, the long-term complications after potassium-titanyl-phosphate photoselective vaporization of the prostate are poorly reported. We describe a rare complication of this technology-calculi formation in the prostatic urethra. All patients presented with visible hematuria and variable lower urinary tract symptoms up to 5 years after the original surgery. In all cases, the calculi were successfully removed endoscopically. Possible causes for this unusual complication are discussed, and the importance of warning patients about this potential long-term complication are highlighted.
