Perinephric and Renal Abscesses

section name header

Information ⬇

Epidemiology and Pathogenesis: Perinephric and renal abscesses are uncommon. More than 75% of these abscesses are due to ascending infection and are preceded by pyelonephritis. The most important risk factor is the presence of renal calculi that produce local obstruction to urinary flow.
Microbiology: E. coli, Proteus spp. (associated with struvite stones), and Klebsiella spp. are the most common etiologic agents; Candida spp. are sometimes identified.
Clinical manifestations: Clinical signs are nonspecific and include flank pain, abdominal pain, and fever. This diagnosis should be considered if pts with pyelonephritis have persistent fever after 4 or 5 days of treatment, if a urine culture yields a polymicrobial flora, if the pt has known renal stone disease, or if fever and pyuria occur in conjunction with a sterile urine culture.

Treatment: Perinephric and Renal Abscesses

Drainage and the administration of antibiotics active against the organisms recovered are essential. Percutaneous drainage is usually successful for perinephric abscesses.
