Discovery of primary hyperparathyroidism following an endoscopic resection of the prostate: case report

Urological complaints related to primary hyperparathyroidism are frequently caused by the formation of urolithiasis. We report another rare clinical manifestation of primary hyperparathyroidism associated with urological symptoms. A 68-year-old man presented with dysuria related to benign prostatic hyperplasia. After undergoing endoscopic resection of the prostate, the patient's urinary complaints persisted for several months thereafter. Urinary ultrasound revealed numerous calcifications on the prostatic resection area, requiring a cystoscopy for excision and analysis of the calcifications. This was followed by an endocrine evaluation that revealed a primary hyperparathyroidism due to a single parathyroid adenoma, which was responsible for the prostatic calcifications and the patient's atypical symptomatology. The clinical evolution was favorable after parathyroidectomy. Symptomatic prostatic calcifications, due to primary hyperparathyroidism, on an area of the endoscopic prostate resection are uncommon. The only treatment is endocrine surgery.
