Abstract

The vesicoureteral reflux ie the most important causative factor in the development of recurrent pyelonephritis and renal scarring. We observed clinical significance of VUR in the patients with acute pyelonephritis. 90 patients with acute pyelonephritis were seen during the period from July 1977 to June 1982. Patients were excluded from this study if there was a history of pregnancy, neurogenic bladder, diabetes mellitus and infravesical obstruction. Excretory urography, endoscopy and voiding cystourethrogram were performed. 15 of 43 patients with acute pyelonephritis examined by VCU, proved to have reflux. Most of them were Fade IIb. The results were as follows. 1. Among 15 patients with reflux, 8 were children. 2. All of 8 patients with recurrent pyelonephritis had reflux, 6 of 8 patients with renal scarring had reflux. 3. 11 of 14 patients with abnormal ureteral orifice had ipsilateral reflux. 4. Medical treatment was successful in 4 of 5 patients with grade I reflux. 5. Surgery was successful in 4 of 5 patients (6/7 ureters)
