Urethral polyp in a 1-month-old child.

Urethral polyps are a rare finding in children, particularly in the very young. They are suspected by the presence of various clinical signs such as obstruction, voiding dysfunction and haematuria. There is an association with other urinary tract congenital anomalies. They are usually benign fibro-epithelial lesions with no tendency to recur and are treated by surgical ablation, fulguration or laser therapy. We report a 1-month-old boy with an antenatally diagnosed left ectopic pelvic kidney, postnatal urinary tract infection and no clinical signs of obstruction. Voiding cystourethrography to exclude vesico-ureteric reflux showed a trabeculated bladder and a mobile filling defect in the posterior urethra. Owing to its large size, cystotomy was necessary to remove the polyp successfully.
