Abstract:
PURPOSE: We investigated if there are some differences in characteristic of recent renal infection from the past one and evaluated the need of ultrasonography in acute renal infection and the efficiency of antibiotics that have been used primarily in treatment of past renal infection. MATERIALS AND METHODS: We reviewed charts of 232 patients with acute renal infection retrospectively, who took admission treatment from 1991 to 1995 at our hospital. The laboratory tests such as complete blood count, urinalysis and urine culture with sensitivity and radiologic evaluations such as abdominal ultrasonography, excretory urography or voiding cystourethrography were performed. RESULTS: The most common age groups were 3rd decade(26.7%) and 4th decade(24.1%). Female was predominant in all age groups(M:F=1:8.7) except 1st decade(M:F=1.6:1). Acute pyelonephritis was the most common disease (87.1%) and then followed by acute focal bacterial nephritis(8.2%), renal abscess(4.3%) and perirenal abscess(0.4%). Five cases(2.2%) were accompanied by vesicoureteral reflux. Abdominal ultrasonography was done in 90.5%, but 74.8% of them were completely normal and most of abnormal findings at abdominal ultrasonography were clinically insignificant. Result of ultrasonography did not affect the outcome of the disease or the treatment plan. The significant bacterial isolation(more than 10(5)CFU/ml) in urine culture was 46.6%. Among them, E. coli was the most common organism(92.6%) and others were Enterobacter, Klebsiella or Pseudomonas. Causative agents were resistant to some drugs such as ampicillin or bactrim which have been usually used for urinary tract infection. CONCLUSIONS: Routine ultrasonography in renal infections without urinary tract obstruction was not helpful in treatment plan or outcome of this disease and selection of antibiotics in treatment of recent renal infection should be changed from the past one.
