  • Title: [Nephrectomy in acute uncomplicated pyelonephritis].
    Author: Knopf HJ, Schulze H.
    Journal: Urologe A; 2004 Nov; 43(11):1416-9. PubMed ID: 15526084.
    Abstract:
    BACKGROUND: Which complications can develop from uncomplicated pyelonephritis that may require nephrectomy? METHODS: From January 1999 to June 2003 we carried out nephrectomy in ten cases due to abscess formation after acute, uncomplicated pyelonephritis. The medical files were evaluated retrospectively. RESULTS: Nine women and one man were involved. The mean age was 36.2 years. Leading symptoms: flank pain, fever and chills. The mean symptom duration before admission was 14.6 days. Urinary tract infections were caused by Escherichia coli (six), E. coli and Enterococcus (once) and Klebsiella pneumoniae (once). Two cultures were sterile. Indications for nephrectomy were urosepsis (7 cases), anuria (once), increasing abscess formation under antibiotic therapy (once), drastic deterioration of general condition (once). CONCLUSIONS: Uncomplicated pyelonephritis is easy to treat under outpatient conditions with adequate oral antibiotic therapy. Close control must be ensured and clear recovery of symptoms should occur within 48 h. In the case of long duration of symptoms (>6-7 days) or lack of improvement of symptoms under calculated therapy in the first 2 days, inpatient therapy should be initiated because of the high risk of infectious complications. According to our experience, the following patient group is especially at risk: female, symptom duration of at least approximately 1 week, pre-treatment and transfer from another departments.
