To observe whether there is any difference in terms of postnatal complications and surgical requirements of fetuses with fetal pyelectasis in their antenatal follow-ups. A total of 199 patients were included in the study. Those with an anteroposterior renal pelvis diameter of 4 to 7 mm were included in the mild pyelectasis group (group1)(n=129), those with 7 to 10 mm in the moderate pyelectasis group (group2) (n=26) and those with 10 to 15 mm in the severe pyelectasis (group3) (n=44). Information such as delivery type, birth week, birth weight and gender of baby were recorded. The diagnoses and surgical requirement rates of babies followed up after birth were obtained from the case record files. Differences between both groups were evaluated. When the complications in the groups were examined, the differences between the groups with multicystic dysplastic kidney (p=0.011) and left ectopic kidney (p=0.028) were found to be significant. Left ectopic kidney was observed only in group3 at a rate of 4.5%. While ureteropelvic stenosis showed a significant difference in group2 and group3 (p<0.0001), this complication was not encountered in group1 at all. While vesicoureteral reflux was observed significantly in group2 and group3 (p=0.003), it was not observed in group1 at all. Normal US findings were detected in 95.3% of the patients and were evaluated as statistically significant (p<0.0001). According to all these data, the total need for surgical procedures in the distribution of postpartum surgical requirements of the groups was found to be 15.6%. No statistical significance was found between the groups according to the pyelectasis grade (p=0.235). Prenatal follow-up of the renal pelvis diameter and the follow-up of the patient in the postnatal period are extremely critical in terms of preventing the development of possible complications. The early diagnosis of pyelectasis ensures that the decision of follow-up and surgery is made within the framework of a regular follow-up.
