ABSTRACT
Dystrophic calcification can be defined as a calcification that occurs in degenerated or necrotic tissue. It is associated with multiple clinical conditions, such as collagen vascular diseases. It involves the deposition of calcium in soft tissues despite no generalized disturbance in the calcium or phosphorus metabolism, and this is often seen at sites of previous inflammation or damage. Potassium-titanyl phosphate (KTP) laser vaporization of the prostate is safe and relatively bloodless procedure that results in a shorter catheterization, immediate symptomatic improvement, and less severe postoperative irritative symptoms. However, longer follow-up studies or reports about complications are lacking. Here in we report a case of dystrophic calcification and stone formation on the entire bladder neck after performing KTP laser vaporization of benign prostate hyperplasia. That was treated by lithotripsy and transurethral resection.

Figure 1: The transrectal ultrasonography showed diffused calcification around the internal urethral sphincter.

Mentions: The laboratory results showed a plasma calcium level of 9.3 mg/dL and a plasma phosphorus level of 4.7 mg/dL, which were both within the normal ranges. The urinary sediment contained 10-29 white blood cells/high power field with 5-9 red blood cells/high power field, and bacterial culture of the urine was sterile. Transrectal ultrasonography of the prostate showed prostate volume of 9 mL and there was diffuse calcification around the internal urethral sphincter (Fig. 1). The cystoscopic findings revealed stones located in the bladder neck, and these were lodged into the previous surgical site. The stones were very tightly lodged into the mucosa of the bladder neck.
