Abstract

Hydronephrosis is the commonest abdominal tumor in infants and children resulted from urinary tract obstruction. The urinary tract obstruction has been defined as a disturbance of the normal pressureflow relationships in the urinary tract and it is only by an increase in pressure that the effects of obstruction are transmitted back to the kidney. This report is a clinical study on 47 hydronephrosis under the age of 15 years which were admitted to the pediatric and urologic department of Dong San Hospital, Keimyung University during the period of 12 years from Jan. 1973 to Dec. 1984. Following results were obtained. Out of 47 cases, 34 cases were male and 13 cases were female showing male to female ratio 2.6:1. The most prevalent age was 2-5 years of 34.1% of total cases. The commonest clinical manifestation was abdominal mass and distention (57.4%) followed by fever (17.0%), flank pain (12.7%) and urinary incontinence with frequency (12.7%). The left side was involved approximately 2 times more than right noting 48.9% and 27.7% respectively. 23.4% were involved bilaterally. The most commonly affected site was ureteropelvic junction. Proteinuria was seen in 27.6%, pyuria in 19.1%, hematuria in 10.6% and pyuria with hematuria in 17.0%. The associated genitourinary diseases were urinary tract infection (11 cases), U-V reflux (8 cases) and ureterocele (5 cases) in order. Surgical treatment was done on 36 cases. Nephrectomy and ureteropyeloplasty were the operations done most frequently. Out of 36 operated cases, 31 cases were recovered and 1 case expired. 7 cases had surgical complications such as ureteral sricture, pyelonephritis, UPJ obstruction and intestinal obstruction.
