Abstract

Nephrogenic adenoma (nephrogenic metaplasia) is a rare benign urological condition, which may present with hematuria, dysuria, and urinary frequency. In the prostatic urethra, it can be misdiagnosed as adenocarcinoma of the prostate. Risk factors for prostatic NA include trauma, infection and prior endourological procedures. We report a case of prostatic NA, presenting with isolated macroscopic hematuria in a man with a history of laser therapy of the prostate for benign prostate hyperplasia, and review the recent literature on the subject.
