Abstract：Objective: To evaluate the diagnostic value of three-dimensional volume ultrasound in fetal hydronephrosis related diseases. Method: 85 pregnant women with fetal hydronephrosis were enrolled in this study. Three-dimensional volume ultrasound was used to measure the volume of kidney and calculate the ratio of renal parenchyma(the total volume of kidney -the hydronephrosis volume)/the total volume of kidney. Meanwhile, the fetal hydronephrosis was graded according to the Society for Fetal Urology(SFU) grading system. The prognosis of children was followed up. And the relationship between renal parenchymal ratio, SFU classification and prognosis was analyzed. Result: This study was included 170 kidneys in 85 fetuses. There were 122 cases diagnosed with renal pyelectasis, 37 cases diagnosed with bilateral renal pelvis dilatation, and 48 cases diagnosed with unilateral hydronephrosis(15 cases of right, 33 cases of left). According to SFU grading system, there were 29 kidneys in grade 0, 21 kidneys in grade 1, 58 kidneys in grade 2, 35 kidneys in grade 3 and 27 kidneys in grade 4, respectively. Three patients chose to terminate pregnancy. According to the follow-up outcomes, all patients were divided into three groups: 14 cases for postnatal surgery, 34 cases for postnatal periodic review(possibly later surgery), 34 cases for postnatal remission(the renal pelvis width was less than 1.0 cm). There was a significant difference in renal parenchymal ratio among different groups(P=0.001). Conclusion: Three-dimensional volume ultrasound combined with SFU classification could provide some helpful information of fetal hydronephrosis related diseases in prenatal diagnosis and counseling.
