Abstract

Purpose
: A study was done to assess the incidence, clinical characteristics of urinary tract anomalies for decreasing urinary tract morbidity.
Methods
: We review 98 cases of anomaly of urinary tract who were admitted Kyung Hee University Hospital between 1986 and 1995. We analyzed incidence and associated anomalies, associated diseases and treatment modalities.
Results
: 1) It was composed of 45 cases(45%) of renal anomalies, 37 cases(37.7%) of ureteral anomalies, 7 cases(7.1%) of urethral anomalies, 3 cases Prune-belly syndrome, 3 cases of urachal remnants, 2 cases of bladder exstrophy, 1 cases of VATER syndrome. 2) Anomalies of the kidney were composed of 14 cases of renal agenesis, 11 cases of multicystic dysplastic kidney, 10 cases of hydronephrosis 3 cases of hypoplasia, 3 cases of polycystic kidney, 2 cases of ectopia, 1 case of malrotation and 1 case of horseshoe kidney, 20 cases(44.4%) were diagnosed before 1 month of life. 20 cases were male and 25 casses were female. Bilateral involvement were in 7 cases and 38 cases of unilateral involvement were composed of 23 cases of right side and 15 cases of left side. Operative treatment were performed in 15 cases(30%) of renalanomalies. The common chief complaint of renal anomalies were abnormal finding on urinalysis(24.4%), abnormal finding on fetal ultrasonogram(20%), gastrointestinal tract symptom(15.6%), and fever(9%). 3) Anomalies of the ureter were composed of 26 cases of ureteral duplication, 9 cases of UPJ obstruction, 2 cases of megaureter. Ureteric duplications included 8 cases of male and 18 cases offemale and 19 cases were unilateraland 7 cases were bilateral.19 cases were diagnosed before 5 years old. 19 cases(73.1%) had symptoms associated with urinary tractinfection.11 cases had abnormal finding of ipsilateral kidney on DMSA scan or IVP. Associated abnormalities were hydronephrosis, ureterocele and VUR. UPJ obstruction were mostly diagnosed before 1 month of life, 6 cases were male and 3 cases were female. 2 cases were bilateral and 3 cases were right side involvement and 4 cases were left side.
Conclusion
: It seems to be reasonable that we should recommend the patients with the symptoms of urinary tract diseases to do evaluate the possibility of congenital urinary tract anomalies.
