Primary UCO was offered only if a discordant lethal anomaly was present or by patient choice in TTTS Stages III\/IV on the cord of the fetus with abnormal Doppler studies or hydrops.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Primary UCO was performed in 25 TTTS cases between July 1997 and June 2002. UCO was performed in six (24%) donor twins and 19 (76%) recipient twins. UCL was performed in 23 cases and UCP in two cases. Overall, 22 (88%) patients had liveborn infants. There were no differences in cotwin survival (100% vs. 84.2%), median gestational age at delivery (34.8 vs. 33.8 weeks) and preterm premature rupture of membranes rate (16.6% vs. 15.7%) whether the donor or recipient twin, respectively, was the subject of UCO. However, two\u2010trocar access (50% vs. 5.3%; <jats:italic>P<\/jats:italic> = 0.03) and amnioinfusion (83.3% vs. 0%; <jats:italic>P<\/jats:italic> &lt; 0.001) were required more often in the UCO of the donor than of the recipient twin, respectively. Operating time (75 vs. 40 min) was significantly longer in UCO of the donor twin (<jats:italic>P<\/jats:italic> = 0.04). UCP was more likely to be used in occlusion of the donor's cord (33%) than of the recipient's cord (0%; <jats:italic>P<\/jats:italic> = 0.05).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Primary UCO of the donor twin is technically more demanding than that of the recipient twin, but perinatal outcomes of the cotwins are comparable.
