Abstract:
A clinical observation was made on 97 cases of hydronephrosis who were admitted to the Urologic Department of the Maryknoll Hospital during the period from July 1, 1976 to December 31, 1981 (5 and 1/2 years). The results are as follows: 1. The rate of hydronephrosis accounted for 8.7% of the total patients (1,109 patients) admitted to the Urologic Department and 20.6% of the patients with urinary tract obstruction (471 patients). 2. The patients in this series were distributed over all ages, from a 12-month-old baby up to a 76-year-old patient. The most common age group Was the 5th decade (29.9%) and the male to female ratio was 1.5 to 1. 3. In underlying diseases, the most common cause of hydronephrosis was ureteral stone (40.2%), and 16.5%was idiopathic. 4. In lateralization of hydronephrosis, the left side was more affected than the right side by about 1.2 times and 19.6% was bilateral. In site and level of obstruction, upper tract was 76.3%, mid and lower tract was 7.2%, intraurinary tract lesion was 97.9% and extraurinary tract lesion was 2.1%. 5. The most commonly obstructed organ was the ureter (59.8%). 6. The most common symptom on admission was flank pain (46.8%). 7. In laboratory findings, increased B.U.N. and creatinine was 11.3%. Pyuria was 58.8% in urinalysis and the most common organism in urine culture was E. Coli (50.0%). 8. The most common complication of hydronephrosis was non-functioning kidney (42.2%). 9. In treatment, surgical treatment was 75.3% and conservative treatment, 24.7%. Of the surgical treatment, the most common operation was nephrectomy (30.9%), while the rate of conserving kidney was 69.1% and about 2.2 times higher than nephrectomy cases.
