PRESENTATION, DIAGNOSIS AND TREATMENT OF RENAL ABSCESSES - 1972-1988

We reviewed 61 consecutive patients with renal abscesses who were treated between 1972 and 1988 to determine whether the patient characteristics and mortality differed from those of patients treated during the preceding 2 decades. The results demonstrate that the predisposing conditions, symptomatology, abnormal physical findings, abnormal laboratory results, abnormal radiographic findings and infecting organisms of patients with renal abscesses have not changed during the last 40 years. Ultrasonography and computerized tomography, which became available in the 1970s, identified 35 of 38 (92%) and 23 of 24 (96%) abscesses, respectively. In 57 cases (97%) the abscess was drained and the patients survived. In 4 cases the abscess escaped clinical detection and contributed to patient death. The marked improvement of survival among patients with renal abscesses during the last 2 decades is attributable to improved diagnostic precision and, probably, improved antimicrobial therapy and supportive care.
