OBJECTIVE: to report a case of fetal urethral stenosis diagnosed and treated by fetal cystoscopy. CASE REPORT: We report a fetus with severe megabladder, 'keyhole' sign that underwent fetal cystoscopy at 22 weeks. There was a familial history of mild urethral atresia. Fetal cystoscopy revealed a congenital urethral atresia. A guidewire was advanced through the fetal urethra and a transurethral vesicoamniotic stent was placed successfully. Fetus was delivered at 37 weeks, confirmed the absence of posterior urethral valves or urethral atresia. The infant is now 5 years old with normal renal function.
CONCLUSION: Fetal cystoscopic placement of a transurethral stent for congenital urethral stenosis is feasible.
