Abstract:

Objective: To evaluate the safety and efficacy of different induction methods in pregnant women in the second trimester with chronic kidney disease (CKD) Stages 3-5. Methods: A retrospective study was conducted on 17 pregnant women with CKD Stages 3-5 who underwent midtrimester induction of labor at the First Affiliated Hospital of Zhengzhou University between October 1, 2019 and September 30, 2023. Patients were divided into two groups based on induction method: the ethacridine group (intra-amniotic injection of ethacridine lactate, n=9) and the balloon catheter group (mechanical dilation with a Foley catheter, n=8). General characteristics, induction outcomes (success rate, induction-to-delivery interval, total labor duration), complications, and renal function before and after induction were compared. Results: No significant differences were observed in induction success rate (88.9% vs. 100.0%, P =1.000), induction-to-delivery time, total labor duration, intra-partum blood loss, fetal weight, or incidence of retained products of conception (all P>0.05). Neither group experienced complications such as postpartum hemorrhage, perineal laceration, placental abruption, disseminated intravascular coagulation, intrauterine infection, uterine rupture, conversion to cesarean section, or puerperal infection. Renal function markers (serum creatinine, blood urea nitrogen, uric acid and estimated glomerular filtration rate) remained stable before and after induction in both groups(all P>0.05). For patients with a scarred uterus, success rate did not differ significantly (P =1.000). Conclusions: Both ethacridine lactate and balloon catheter methods are safe and effective for induction of labor in the second trimester in CKD Stages 3-5 patients, without increasing complication risks. However, each method has specific advantages and limitations. Multidisciplinary collaboration is recommended to select individualized induction strategies.
