ABSTRACT

Purpose : Congenital urinary tract anomaly is the most common anomaly in the childhood and progress to chronic renal failure and growth retardation. Therefore, early diagnosis arid treatment of urinary tract anomaly are important. Method : We reviewed medical records of 124 patients who had urinary tract anomalies on radiologic studies from Jan. 1986 to Dec. 1996. We analyzed demography and clinical characteristics of urinary tract anomalies.
Results : 1) The age distributions were as follows ; 61 cases of 124 patients (49%) were under 1 year, 11 cases (8.8%) from 1 to 3 years, 20 cases (16%) from 4 to 6 years, 10 cases (8%) from 7 to 9 years, 9 cases (7.2%) from 10 to 12 years, 10 cases (8%) from 13 to 15 years, and 3 cases (2.4%) from 16 to 18 years. 2) Chief complaints in patients with urinary tract anomalies were fever, flank pain, prenatally diagnosed hydronephrosis, abdominal mass, dysuria and hematuria. 3) Of 124 patients, 68 cases(54.8%) were combined with urinary tract infection, and main causative organism was E.coli, and the most frequently associated anomaly was vesicoureteral reflux. 4) Most of the urinary tract anomalies were VUR, UPJ obstruction, congenital hydronephrosis and double ureter in order of sequence. 5) Whereas the frequency of simple urinary tract anomaly was 87.9%, that of complex anomaly was 12%. 6) Operative corrections were needed in 47 cases and 7 cases were progressed to renal insufficiency.
Conclusion : We emphasize that early detection of urinary tract anomaly, appropriate treatment and regular follow-up are needed.
