Objectives: Usefulness on exploration of intracavity pathologies and their impact on fertility.

Virtual poster abstractsResults: There were 86 cases with fetal CAKUT, median gestational age at diagnosis was 22 weeks and at termination was 38 weeks. Hydronephrosis 52 (60.4%) was the most common CAKUT observed followed by parenchymal diseases 24 (27.9%) and Left kidney (54%) was more often affected in unilateral cases. None of the fetuses with (6.9%) Bilateral renal agenesis survived. Low survival rate was observed for bilateral parenchymal diseases (24 cases), 14 (16.2%) of which had abortion or intrauterine/neonatal death. Significant association observed between right and left kidney size, right and left parenchyma measurements, bladder size and AFI with outcome of pregnancy. Associated anomalies were present in 23 (26.7%) cases. In 51 live babies followed up post-natally, spontaneous resolution was seen in 16 (31.4%), 18 (35.2%) were unresolved but asymptomatic while 17 (33.3%) required treatment with surgical intervention done for 8 cases (15.6%). Conclusions: Severe CAKUT diagnosed in earlier gestation has poor outcome, non-obstructive hydronephrosis has good prognosis compared to obstructive type, parenchymal disease is associated with poor outcome while unilateral CAKUT is associated with good outcome. Amniotic fluid index, associated anomalies and ultrasound parameters like size of kidneys, anteroposterior diameter of pelvis, parenchymal thickness influences the prognosis.
