Renal and perinephric abscess are uncommon diseases with a multitude of clinical presentations. In past morbidity and mortality were high rate because of delay in diagnosis. Diagnosis and treatment approaches were challenged recently by newer imaging modalities as ultrasonography and CT scanning and by interventional uroradiology.
A clinical observation was made in 9 patients with renal abscess and 1O patients with perinephric abscess admitted in the Dept. of Urology, Kyung Hee University Hospital during the period from Jan. 1981 to Jan. 1986.
The following results were observed:
1. Among 19 patients, 11 patients were women and their age was ranged from 22 to 68 yrs old with mean of 44.5 yrs. In 12 cases, Lt. kidneys were involved.
2. In 5 patients who had positive urine culture, E. coli was recovered in 3 cases, and klebsiella sp. and staph. epldermidis were recovered in one case, respectively. Blood culture was positive in one case. Among 14 cases performed pus culture, bacteria was recovered in 8 cases: E. coli in 4 cases staph. aureus in 2 cases, and staph. epldermidis and peptococcus in one case, respectively.
3. In 15 cases, diagnosis could be confirmed by ultrasonography, but CT scan was needed in 4 cases to confirm the nature of lesion. The common findings of ultrasonogram were mixed echogenic mass and echolucent mass found in 8 cases and 7 cases, respectively.
4. Among 19 cases, 1O patients underwent open drainage, 5 cases were treated by antibiotics only, and 3 cases were managed successfully by closed drainage.
