Abstract

Twin to twin transfusion syndrome (TTTS) is a rare complication of monochorionic twin pregnancies. Posterior urethral valves (PUV) is the main cause of urethral obstruction found almost exclusively in male embryos. A 23 – year – old gravida 1 para 0 presented in our department with diamniotic monochorionic twins at 21 weeks of gestation for ultrasound B – scanning and TTTS accompanied with PUV was diagnosed. The first trimester screening test for nuchal translucency was normal. This case presentation can provide more information regarding the pathophysiology of TTTS.
