title: [Congenital urethral polyps. A rare cause of obstructive uropathy in childhood].
abstract: Congenital urethral polyps are an extremely rare cause of obstructive uropathy in childhood. Obstructing polyps arise on the seminal colliculus or the floor of the prostatic urethra. They are pedunculated, and the stalk can be several centimetres in length. Primarily they are composed of connective tissue covered by epithelium. Additionally, smooth muscles and islands of glandular cells and even nerve tissue have been found. We present three cases of children with congenital posterior urethral polyps causing severe infravesical obstruction. In two cases the polyps were excised at open cystotomy and in one case, transurethrally. The follow-up investigations confirmed a good prognosis of these patients: micturition behaviour had normalized and the symptoms of urinary obstruction had either markedly improved or completely disappeared. Dilatation of the upper urinary tract and loss of function resulting from recurrent urinary tract infection remained stable after relief of the obstruction by polypectomy.
