Abstract
Objective: The majority of antenatal hydronephrosis disappears spontaneously. In our study, we haveinvestigated the effective predictors for surgical decision in antenatal hydronephrosis.Material and methods: Forty-four patients found to have renal pelvic anteroposterior (AP) diametermore than 10-mm on antenatal ultrasonograpy were followed after birth. The study groups were dividedinto two groups: follow-up and surgery group. On follow-up, longitudinal diameter of the kidney,parenchymal thickness of the kidney, AP diameter of renal pelvis, AP diameter of middle calyces onultrasonograpy, and differential renal function, 20th minute clearance, half-life of radionuclide tracer(T1/2), Tmax, Tmax-T1/2, normalised residual activity (NORA) on diuretic renography were evaluated.Ultrasonograpy and diuretic renography measurements were compared in patients whose hydronephrosisresolve or proceeded to surgery.Results: Forty-four patients were diagnosed as antenatal hydronephrosis, spontaneous resolution occurredin 23 (52%), and surgery was performed in 21 patients (48%). Mean age at operation was 8.5±6.5months (3-24 months). Mean AP diameter of renal pelvis was 29.5±14.2 mm for surgery group, 13.6±4.2mm for follow-up group (p
Özet
Amaç: Antenatal hidronefroz (AHN)’ların birçoğu doğumdan sonra kendiliğinden gerilemektedir. Çalışmamızda AHN’ların takibinde alınan ameliyat kararında etkili belirteçler araştırıldı. Gereç ve yöntemler: Antenatal ultrasonografi (USG)’de renal pelvis anterior posterior (AP) çapı 10-mm’den fazla olan hastalar doğumdan sonra takip edildiler. USG’de, böbreğin uzun ekseni, böbrek parankim kalınlığı, renal pelvis AP çapı, orta kaliks AP çapı; diüretik renografi (DRG)’de, diferansiyel renal fonksiyon, 20. dakika klirens, T1/2, Tmax, Tmax-T1/2, normalleştirilmiş artık etkinlik (NORA: normalised residual activity) değerlendirildi. Takip sırasında hidronefrozu gerileyen veya ameliyat edilen hastalarda USG ve DRG ölçümleri karşılaştırıldı. Bulgular: AHN tanısı alan 44 hastanın 23’ünde (%52) hidronefroz kendiliğinden geriledi, 21’inde (%48) ameliyat yapıldı. Ortalama ameliyat yaşı 8,5 ay (3-24 ay) idi. Renal pelvis AP çapı takip grubunda 13,6±4,2 mm, ameliyat grubunda 29,5±14,2 mm hesaplandı (p
