Solitary polyp of posterior urethra in children: report on seventeen cases.

Seventeen cases of a solitary polyp of posterior urethra in children (ages ranged between 4 months and 12 years) are presented. All patients were treated endoscopically using a 10 Fr. pediatric cystoscope, equipped with a straight ahead lens, and a Bugbee 3 Fr. electrode to fulgurate the stalk of the polyp through the urethra, without meatotomy. No complications or relapses are recorded, which proves the safety and the efficiency of the transurethral endoscopic resection in all pediatric ages. With the exception of one case, the smallest polyp of the series, lost because entirely burnt during the electrocution, all polyps were recuperated and examined histologically. The dimensions of the polyps ranged from 4 mm to 27 mm length. Their shape varied from a long "cordon-like" peduncle to a short stalk, "balloon-like" appendix. The histologic features were similar, the main component was an axis of connective tissue and vessels, surrounded by transitional epithelium, usually described as a fibroepithelial polyp.
