  • Title: Cystoscopic placement of transurethral stent in a fetus with urethral stenosis.
    Author: Ruano R, Yoshizaki CT, Giron AM, Srougi M, Zugaib M.
    Journal: Ultrasound Obstet Gynecol; 2014 Aug; 44(2):238-40. PubMed ID: 24375864.
    Abstract:
    We report the case of a fetus with severe megabladder, displaying the 'keyhole' sign on ultrasound imaging, that underwent cystoscopy at 22 weeks' gestation. There was a familial history of mild urethral atresia. Fetal cystoscopy revealed congenital urethral atresia. A guide wire was advanced through the fetal urethra and a transurethral vesicoamniotic stent was placed successfully. The fetus was delivered at 36 weeks' gestation and postnatal cystoscopy confirmed the absence of posterior urethral valves or urethral atresia. The infant was 5 years old with normal renal function at the time of writing. We conclude that fetal cystoscopic placement of a transurethral stent for congenital urethral stenosis is feasible.
