Most adults with uncomplicated acute pyelonephritis pose no diagnostic or therapeutic problems and recover fully. When imaging is requested in these cases, CT scan with and without contrast enhancement is preferable; however, depending on the condition of the patient and preference of the clinician an IVU, sonogram, or radionuclide scan may also provide adequate information. Patients at higher risk for complications, such as renal or perinephric abscesses with or without PHN and EPN, require aggressive and vigorous clinical and radiologic monitoring. CT scan is superior to other imaging modalities in the investigation of these complications. Interventional percutaneous procedures are established as safe and effective means of controlling or curing the infection in many patients and are often chosen over traditional surgical technique. The radiologist thus is an indispensable member of the management team and should be available for consultation and intervention.

Emphysematous pyelitis (EP) is a benign entity. To our knowledge, it has not been reported frequently in the radiology literature. Previous articles have not focused on EP but rather have included other gas-forming entities (eg, emphysematous pyelonephritis [EPN]). The authors describe imaging findings in EP and distinguish them from findings in EPN in five cases. Computed tomography is the current method for demonstrating isolated gas production inside the urinary collecting system. The prognosis is excellent, with rapid complete recovery after medical treatment.

The entities described in this article represent processes that arise from, or can be mistaken for, common GU infections. It might be difficult to determine the point at which pyelonephritis develops into EPN or perinephric abscess. It might be equally challenging to distinguish scrotal cellulitis from Fournier's gangrene; however, as most EPs will acknowledge, the mere awareness of these entities in the appropriate clinical circumstances might be enough to prevent a "near-miss" of a surgical emergency.

Emphysematous (Gas-forming) pyelonephritis (EPN) is a rare and life-threatening infection of the renal parenchyma with or without involvement of the peri-renal tissues. Diagnosis of this condition is usually made on clinical and radiological grounds. Risk factors for this condition include diabetes mellitus, urinary tract obstruction, renal anomalies such as polycystic kidneys, stones, old age and others. Review of the literature did not reveal any reports of (EPN) in the pediatric age group especially in transplanted patients. We report the first case of EPN in a child, a 12-yr-old boy with a renal transplant, and discuss the various diagnostic and management issues of this particular case and EPN in general.
