A 69-year-old patient who underwent photovaporization of the prostate (PVP) with GreenLightTM Laser presented chronic abdominal pain, in the following and after 7 months, an abdominal MRI showed a bladder mass and the cystoscopy revealed an 8 cm of diameter grayish mass of the anterior wall and the dome. Malignancy, infectious, and granulomatous diseases were ruled out. Biopsy showed necrotic tissue and dystrophic calcification (DC) with crystals and Gram-positive cocci, so a transurethral resection was intended failed due to the mass hard consistency and size. The patient was taken to partial cystectomy and the pain resolved. DC is defined as inappropriate deposits of calcium phosphate salts in previously damaged tissue by different forms of trauma: burns, radiotherapy, and surgery. We suggest the DC process is linked to a previous thermal lesion of the bladder during PVP and believe future studies of association can be relevant.
一名69岁接受了绿激光前列腺汽化术（PVP）的患者出现慢性腹痛，术后7个月，腹部MRI显示膀胱有肿块，膀胱镜检查发现前壁和顶部有一个直径8厘米的灰白色肿块。排除了恶性、感染性和肉芽肿性疾病。活检显示坏死组织以及伴有晶体和革兰氏阳性球菌的营养不良性钙化（DC），由于肿块质地硬且尺寸较大，经尿道切除术未能成功实施。患者接受了部分膀胱切除术，疼痛得以缓解。DC被定义为磷酸钙盐在先前因不同形式创伤（烧伤、放疗和手术）而受损的组织中不适当的沉积。我们认为DC过程与PVP期间膀胱先前的热损伤有关，并相信未来关于两者关联的研究可能具有重要意义。
