Maternal congenital renal tract anomaly as a possible risk factor for preterm prelabor rupture of membranes and placental abruption: a rare case of contracted kidney with duplex ureter

Abstract

Congenital renal tract anomalies are uncommon in pregnancy but may predispose to adverse obstetric outcomes. We report the case of a 26-year-old primigravida with a contracted kidney and duplex ureter who developed preterm prelabor rupture of membranes (PPROM), followed by placental abruption at 32 weeks of gestation. Chronic structural renal abnormalities may contribute to recurrent infections and persistent inflammation, leading to weakening of foetal membranes and vascular compromise. This case highlights a possible pathophysiological association between congenital renal anomalies, PPROM and placental abruption. Early recognition and multidisciplinary management are essential to optimize maternal and fetal outcomes.
