[Antenatal screening of uropathies. A 4-year experience, 147 patients]

We have received 147 patients with an antenatal diagnosis of uropathy confirmed after birth. Surgery during the first 3 months of life was necessary for 78 (54%) of them. The procedures included partial or total exeresis of the kidney in 9 cases, and reconstruction of the excretory pathway in 69 (88%). The renal function is normal in all cases, and one failure of surgery only was noted. Four children with pelviureteral obstruction had infections in spite of the antenatal screening, as did one child with reflux. One child remained with a postoperative urinary infection, which can be attributed to contralateral reflux. In surgery of the renal pelvis, as well as in the reimplantation of thin ureters, no tube was left in place, thus reducing the stay in hospital and the risk of post-operative infection. The children were admitted to hospital with their mothers in 95% of all cases.
