ABSTRACT
Purpose : A study was done to assess the incidence and classification of congenital urinary tract anomalies detected by antenatal ultrasonogram.
Methods : We reviewed 558 cases of urinary tract anomaly which were detected by antenatal ultrasonogram and postnatally confirmed between June 1989 and May 2002. We investigated the incidence and classified congenital urinary tract anomalies by review of medical records, antenatal and postnatal radiologic studies retrospectively.
Results : In 558 cases of congenital urinary tract anomalies, 292 cases of hydronephrosis were found and the most common. Another anomalies were composed of 65 cases of multicystic dysplastic kidney, 32 cases of hydroureteronephrosis, 31 cases of duplication of kidney, 25 cases of renal agenesis, 21 cases of simple renal cyst, 20 cases of polycystic disease, 13 cases of ureterocele, 11 cases of renal hypoplasia, 10 cases of horseshoe kidney, 9 cases of vesicoureteral reflux, 8 cases of posterior urethral valve, 7 cases of bladder diverticulum, 6 casts of megaureter, 5 cases of ectopia, 2 cases of megacystis, and 1 case of medullary cystic disease. In 82 of the 558 cases, there were two or more combined urinary tract anomalies. Associated diseases other than urinary tract were observed in 13 cases, of which the congenital heart disease was the most common.
Conclusion : The congenital urinary tract anomaly is frequently found and diverse during the antenatal ultrasonography. The multicenter study is needed to investigate precise incidence and distribution of each anomalies in general population.
