A Clinical Observation on 11 Patients of Postrenal Acute Renal Failure / 대한비뇨기과학회지

ABSTRACT

A clinical evaluation was done on Il patients with postrenal acute renal failure who were admitted to the Busan National University Hospital during the period of 6 years and 8 months from Jan. 1976 to Aug. 1982. The results were as follow. 1. The patients were mean ages of 44.3 years, being thought somewhat older than other cause of renal failure. And the male was more frequently affected than the female. 2. The 2 most common causes of postrenal acute renal failure in 11 patients were malignant neoplasms (5 patients; 1 bladder Ca. 3 cervical Ca. and 1 retroperitoneal metastatic Ca.) and ureteral calculi (5 patients; 2 bilateral and 3 unilateral in solitary renal unit). 3. Ureteral obstructions were bilateral in 7 patients (14 ureters) and unilateral in 4 patients (4 ureters) in the solitary kidney. The involved site of ureteral obstructions were bilateral lower ureters in 5 patients (10 ureters), bilateral upper ureters in 1 patient (2 ureters), unilateral right upper ureter and left lower ureter in 1 patient 12 ureteral, and unilateral lower ureter in 4 patients (4 ureter). 4. Seven patients were treated with urinary diversion, 3 with ureteral catheterization and 1 with ureterolithotomy. Among 7 patients of urinary diversion, nephrotomy was done in 6 patients and double-barreled ureterocutaneostomy in 1 patient. 5. The prognosis was excellent in 10 patients and 1 patient was expired due to uremia and generalized marasmus following malignant neoplasm.
