title: Perinephric abscess in renal transplant recipients: report of seven cases and review.
abstract: The experience of four kidney transplantation programs from 1975 to 1986 was reviewed to determine the prevalence and clinical characteristics of perinephric abscess in renal transplant recipients. Seven cases were found, with a prevalence of 0.3% in 1,945 patients seen over a 12-year period in one program. Current prevalence appears markedly less than in older studies. Despite immunosuppression, signs and symptoms of perinephric abscess were prominent and included fever, flank and abdominal pain and tenderness, and abdominal mass. Perinephric abscesses were diagnosed 2 weeks to 52 months after transplantation and were associated with lymphoceles in two patients. Abdominal ultrasound and computed tomography were useful in diagnosis. Staphylococci (36%) and aerobic gram-negative rods (32%) were the most common pathogens in our seven patients combined with patients identified in a review of the English-language literature. Also of note were the presence of anaerobes (28%) and Candida albicans (4%). Therapy was successful in all of our seven patients.
