Management of prenatally diagnosed uropathies is controversial, mainly because the prognosis for these fetuses is quite different. However pioneering studies have shown that prenatal drainage of obstructed urinary tract can improve the outcome of selected fetuses. The aim of this study is to describe the experience of the Service with the treatment of fetal obstrutive uropathy with the catheter developed by the Centro de Medicina Fetal do Hospital das Clínicas da UFMG. A total of 25 fetuses with obstructive uropathy received the catheter. Three fetuses required more than one insertion. Ten of 25 (40%) shunted fetuses survived with good postnatal renal and pulmonary function. Complications occurred in 12/25 (48%) cases including: 06/25 (24%) inadequate shunt drainage or migration; 01/25 (04%) urinary ascitis; 01/25 (04%) DPP, 01/25 (04%) premature rupture of membranes, 02/25 (08%) premature labor, 01/25 (04%) scarring and fibrosis of the renal parenchyma. Three of 25 (12%) fetuses died intra-utero and 12 (48%) died during the neonatal period. In conclusion, the drainage of the obstructed urinary tract with this catheter proved to be technically feasible and safe for both mother and fetus, with a survival rate of 40%.

Purpose: to evaluate the intrauterine treatment of anemic fetuses that underwent intrauterine transfusions due to rhesus isoimmunization. Methods: the authors studied sixty-one fetuses undergoing intrauterine transfusions by the intravascular, intraperitoneal or both routes. The hydropic fetuses (19.7%) received only intravascular intrauterine transfusions. There was an overall number of 163 intrauterine transfusions with a mean of 2.7 procedures for each case. The indications for intrauterine transfusions were high values of bilirubin in amniotic fluid analyses by the Liley method or a hemoglobin concentration of cord blood below 10.0 g/mL. Results: the overall perinatal survival rate was 46% for hydropic fetuses and 84% for the nonhydropic ones. There were no maternal side effects related to the procedures. Half of the intrauterine transfusions were performed by the intravascular route. The mean gestational age at the delivery was 34.8 weeks. Conclusions: despite better perinatal results with intrauterine transfusions guided by ultrasound, especially using intravascular procedures, rhesus isoimmunization remains as an important cause of high rates of perinatal morbidity and mortality.
