Abstract

Objective: Symptomatic hydronephrosis occurs in a small subset of pregnancies and may require temporary drainage when conservative management fails. Ureteral Double-J stenting (DJS) is an effective intervention, yet data on maternal and fetal outcomes remain limited. To evaluate maternal and fetal outcomes following DJS placement for symptomatic hydronephrosis during pregnancy and to identify clinical factors associated with stent revision. Material and Methods: This retrospective, single-center cohort was conducted at Kayseri City Hospital, Departments of Urology and Obstetrics & Gynecology (Turkey) between January 2020 and October 2025. Thirty-one pregnant patients who underwent DJS placement for symptomatic hydronephrosis (without obstructive ureteral calculi) were included. Demographic, clinical, and perinatal data were collected from electronic medical records. The primary outcome was a composite adverse perinatal outcome (preterm delivery <37 weeks and/or neonatal intensive care unit [NICU] admission and/or 5-minute Apgar score <7). Secondary outcomes included stent revision and hospital stay. Descriptive statistics and exploratory comparisons were performed. Results: Mean maternal age was 26.2±6.3 years. The mean maximum anteroposterior (AP) diameter was 21.6±8.4 mm, with AP ≥20 mm in 14 patients (45.2%). Stent revision was required in 4 patients (12.9%). Preterm birth occurred in 5 patients (16.2%), NICU admission in 3 patients (9.7%), and mean birth weight was 2884±324 g. Earlier gestational age at stent insertion was significantly associated with stent revision (p=0.017). Conclusion: DJS placement for symptomatic hydronephrosis during pregnancy is generally safe and effective, with favorable maternal and neonatal outcomes. Early gestational stenting may increase revision risk, emphasizing close follow-up, infection surveillance, and timely reassessment of stent function.

Özet

Amaç: Semptomatik hidronefroz gebeliklerin küçük bir alt kümesinde görülür ve konservatif yönetim başarısız olduğunda geçici drenaj gerektirebilir. Üreteral Double-J stentleme (DJS) etkili bir müdahaledir, ancak maternal ve fetal sonuçlara ilişkin veriler sınırlı kalmaya devam etmektedir. Gebelikte semptomatik hidronefroz için DJS uygulanmasını takiben maternal ve fetal sonuçları değerlendirmek ve stent revizyonu ile ilişkili klinik faktörleri belirlemek. Gereç ve Yöntemler: Bu retrospektif, tek merkezli kohort, Kayseri Şehir Hastanesi Üroloji ve Kadın Hastalıkları ve Doğum Bölümleri'nde (Türkiye) Ocak 2020 ile Ekim 2025 tarihleri arasında gerçekleştirilmiştir. Semptomatik hidronefroz (obstrüktif üreteral taşlar olmadan) nedeniyle DJS yerleştirilen otuz bir gebe hasta dahil edildi. Demografik, klinik ve perinatal veriler elektronik tıbbi kayıtlardan toplandı. Birincil sonuç bileşik bir advers perinatal sondu (37 haftadan küçük preterm doğum ve/veçte neonatal yoğun bakım ünitesi [YYBÜ] yatışı ve/veçte 5 dakikalık Apgar skoru <7). İkincil sonuçlar stent revizyonu ve hastanede kalış süresini içeriyordu. Tanımlayıcı istatistikler ve keşfedici karşılaştırmalar yapıldı. Bulgular: Ortalama anne yaşı 26,2±6,3 yıldı. Ortalama maksimum anteroposterior (AP) çap 21,6±8,4 mm idi ve 14 hastada (%45,2) AP ≥20 mm idi. 4 hastada (%12,9) stent revizyonu gerekmiştir. 5 hastada (%16,2) erken doğum, 3 hastada (%9,7) YDYB yatışı gerçekleşti ve ortalama doğum ağırlığı 2884±324 g idi. Stent takılmasındaki daha erken gebelik yaşı, stent revizyonu ile anlamlı düzeyde ilişkiliydi (p=0,017). Sonuç: Gebelikte semptomatik hidronefroz için DJS yerleştirilmesi, olumlu maternal ve neonatal sonuçlarla birlikte genellikle güvenli ve etkilidir. Erken gebelikte stent takılması revizyon riskini artırabilir; bu durum yakın takip, enfeksiyon gözetimi ve stent fonksiyonunun zamanında yeniden değerlendirilmesini vurgulamaktadır.
