From Prostate Enlargement to Bladder Stone: Large Bladder Stone as a Complication of Long-Standing BPH: A Case Study.

Vesicular calculi, or bladder stones, are a common occurrence in males of older age. Although there is a variety of different etiologies reported, one of the less common ones includes a background of benign prostatic hyperplasia (BPH). This case report describes a rare presentation of a large vesicular calculus in an old male patient that was diagnosed along with BPH. The patient, with a history of alcohol abuse and hypertension, previously had a percutaneous nephrolithotomy. Diagnosis was confirmed through transrectal ultrasound, x-ray Kidney-Ureter-Bladder, and cystourethroscopy. He underwent transurethral resection of prostate and open vesicolithotomy, with a smooth recovery. This case highlights the pathophysiological and urodynamical relationship between bladder stones formation and BPH, and explores other factors in stone formation.
