| Popis: | Cilj: Polipi stražnje uretre u muške djece rijetke su i obično benigne kongenitalne lezije. U ovom radu prikazat ćemo slučaj osmogodišnjeg dječaka koji je po drugi put primljen u bolnicu zbog akutne retencije urina (ARU) uzrokovane polipom stražnje uretre. Prikaz slučaja: Kod prvog primitka dječaka u bolnicu, zbog ARU-a, učinjene su uretrocistoskopija i cistouretrografija. No, navedenim pretragama nije se uspio pronaći uzrok dječakovim tegobama. Njegovo mokrenje postupno se normaliziralo i dječak je otpušten kući. Dvije godine kasnije, kada je ponovno primljen zbog ARU-a, ultrazvukom (UZ) je uočena polipoidna tvorba na bazi mjehura i defekt punjenja na mikcijskoj cistouretrografiji (MCUG). Magnetskom rezonancijom (MR) točno se definiralo mjesto na kojem se nalazi polip; s ishodištem u verumontanumu i protruzijom u mokraćni mjehur, gdje slobodno prominira. Nakon transuretralne resekcije učinjena je patohistološka analiza kojom je potvrđen fibroepitelni polip koji je vrlo vjerojatno kongenitalan. Rasprava: Uretralni polipi izuzetno su rijetki, a njihova etiologija je stalna tema rasprave. Prezentirajući simptomi su intermitentna retencija urina, nepotpuno pražnjenje mjehura, hematurija i urinarna infekcija. Mogu biti i asimptomatski, ali rijetko. Dijagnoza se obično postavlja s UZ-om i MCUG-om. MR definira kirurški pristup polipoznoj tvorbi, dok se uretrocistoskopijom postavlja definitivna dijagnoza. Zaključci: Dijagnoza uretralnog polipa može se postaviti sa UZ, MCUG i MR, ali uretrocistoskopija ima važnu ulogu, kako dijagnostičku, tako i terapijsku. Aim: Polyps of the male posterior urethra are rare and usually benign congenital lesions. We report a case of an 8-year-old boy who presented with recurrent urine retention caused by urethral polyp. Case report: At his first admittance to the hospital, the 8-year-old boy presented with urine retention. The performed urethrocystoscopy and cystourethrography were not diagnostic. His condition spontaneously improved, micturition was normal and the boy was discharged. Two years later he presented with recurrent urine retention, and ultrasonography (US) revealed a polypoid mass at the bladder base while cystourethrogram showed a filling defect. Magnetic resonance imaging (MRI) revealed the localization of urethral polyp projecting from verumontanum into the bladder cavity. After successful transurethral resection, histological analysis showed fibroepithelial polyp indicating congenital origin. Discussion: Urethral polyps are very rare and their etiology is controversial. The presenting symptoms are intermittent urine retention, incomplete bladder emptying, hematuria and urinary infection. Rarely, they are asymptomatic. The diagnosis is usually made by US and voiding cystourethrogram (VCUG). Urethrocystoscopy is always diagnostic. The role of MRI is to define the surgical approach to the polypoid lesion. Conclusions: The diagnosis of urethral polyp can be made by US, VCUG or MRI but urethrocystoscopy still has a major diagnostic and therapeutic value, especially in boys presenting with urine retention. |
