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.

The histologic examination of the surgical specimen showed multiple dark basophilic calcifications (arrows) with a background of fibrotic stroma (Hematoxylin and eosin staining, original magnification: ×100).

Figure 4: The histologic examination of the surgical specimen showed multiple dark basophilic calcifications (arrows) with a background of fibrotic stroma (Hematoxylin and eosin staining, original magnification: ×100).

Mentions: Cystoscopic examination was performed again under general anesthesia. The entire bladder neck was encircled by stones and even in the mucosa of the bladder neck. The stones were so tightly lodged into the mucosa of the bladder neck that they couldn't be disintegrated by performing lithotripsy in situ. Therefore, transurethral resection was performed on the mucosal-lodged stones and the calcified tissues (Fig. 2). The stones were bright yellowish (Fig. 3); they were determined to be calcium with phosphate on analysis. Hematoxylin and eosin staining of the surgical specimen showed extensive basophilic staining that was suggestive of calcification within the fibrotic tissues (Fig. 4).
