Posterior urethral polyps are benign polypoid lesions arising from verumontanum or somewhere of prostatic urethra and cause bladder outlet obstruction, hematuria and urinary infection (1-7). The widespread use of high-quality excretory urography, cystourethrography, ultrasound and cystourethroscopy has led to an increased recognation of these rare lesions (3). Posterior urethral polyps should be considered and investigated in boys and young adults presenting with hematuria and nonspesific voiding disturbances. Conventional treatments of posterior urethral polyps are open cystotomy, transurethral resection or fulguration of the polyps and removing of the polyp via laser (8). In view of the rarity of these lesions here in we report our experience with three cases of urethral polyps and outline the diagnostic evaluation and treatment. Case reportsBetween 1992-1999, 3 patients with posterior urethral polyps were seen at our clinic. All of them presented with obstructive voiding complaints and painless gross hematuria. Two of the patients had normal excretory urograms but one of them showed the filling deffect in the base of the bladder (Fig. 1) and antegrade urethrogram showed well-defined urethral filling deffect and venous leakage in the adult (Fig. 2).Cystourethroscopy revealed three polyps, 2 of them arising from verumontanum and one of them in the prostatic urethra. Polyps were resected transurethrally. In one boy after transurethral resection the polyp migrated into the bladder but we retreived it with a broken resectoscope loope (like a fish-hook) avoiding open cystotomy. All of the specimens of histopathologic examination showed fibroepithelial benign polyps.Posterior urethral polyps may cause hematuria, various voiding disorders, out flow obstruction and urinary infections in boys and adults. We report three case of posterior urethral polyps two of them in boys and one of them in an adults. These rare lesions should be considered in the differential diagnosis of hematuria and lower obstructive urinary symptoms in boys and adults.Key Words: Posterior urethral polyp, obstructionPosterior ürethral polipler çocuklarda ve yetişkinlerde hematüri, işeme bozuklukları, çıkış obstrük-siyonu ve idrar yolu enfeksiyonlarına neden olabilirler. Burada ikisi çocukluk çağı, biri yetişkin dönemde görülen üç posterior ürethral polip olgusu sunulmaktadır. Ender görülen bu lezyonlar hematüri ve alt üriner sistem obstrüksiyonlarının ayırıcı tanısında akılda tutulmalıdır.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
