Abstract
THE AIM:to describe the causes, pathogenesis, clinical course and outcome of Potter sequence in children with cystic kidney disease. PATIENTS AND METHODS:the follow-up study of 23 newborns with cystic kidney disease was studied, in which renal oligohydramnios (ROH) was confirmed prenatally by ultrasound (US). RESULTS:Of the 155 children with autosomal dominant polycystic kidney disease (ADPKD), 8 (5,2 %) prenatal after 30 weeks of gestation established ROH, at 26-32 weeks of gestation – cyst in the kidney by US, in 2 of them ROH confirmed simultaneously with the detection of cysts in kidneys of a fetus, 6 – late detection of kidney cysts. Of the 8 newborns with a very early onset ADPKD, prenatal developed in ROH conditions, in 2 (25 %) in the neonatal period diagnosed the Potter phenotype. Of the 20 children with autosomal recessive polycystic kidney disease (ARPKD), 12 (60 %) prenatally revealed ROH after 18 weeks of gestation prenatally, of these, 8 (67 %) in the neonatal period diagnosed the Potter phenotype. Of the 12 newborns with ARPKD, that developed in ROH conditions, in 5 (42 %) kidney cysts were detected prenatally by US at 32-37 weeks of gestation, in 7 (58 %) in the neonatal period. ROH and the Potter phenotype are more common with ARPKD in the fetus than with ADPKD. Among children with ARPKD and ADPKD undergoing ROH, no statistically significant differences in the frequency of deaths in the neonatal and infancy. The characteristics of course and outcome of the Potter sequence in the neonatal and infant periods in a boy with deletion of 12p and cystic kidney disease are described. ROH in 2 children with cystic kidneys and coloboma of the optic nerve disc did not lead to the formation of the Potter phenotype. In 15 children with multicystic kidney prenatal US showed no ROH. CONCLUSION: the results of a follow-up study of children after ROH and the course of the Potter sequence for different cystic kidney disease in children are presented.
