Urethral polyposis in adolescence

: Polyps in the urinary tract are a rare entity in infants and children. The most frequent location when they appear is the ureter. These benign lesions with no malignant potential have a varied form of presentation and in most cases must be distinguished from malignancy. The suspected diagnosis is due to urinary obstruction; nevertheless radiological evidence played a key role in the final diagnosis. The management is as less invasive as possible, with endoscopy resection or minimally invasive surgery.
