1/4. Emphysematous pyelitis presenting as an acute abdomen in an end-stage renal disease patient treated with peritoneal dialysis.

    Emphysematous pyelitis is air in the renal collecting system in patients with urinary tract infections. This entity is uncommon and seen primarily in patients with diabetes mellitus. We report a case of a patient with end-stage renal disease treated with peritoneal dialysis who developed emphysematous pyelitis who presented with signs and symptoms that were more consistent with appendicitis. The spectrum of infections causing air in the urinary tract and the method by which end-stage renal disease patients are treated are discussed. patients receiving dextrose peritoneal dialysis are at risk for emphysematous pyelonephritis, pyelitis, and cystitis.

2/4. Emphysematous pyelitis and emphysematous pyelonephritis characterized by computerized tomography.

    We report three cases of emphysematous pyelonephritis, all of them associated with perinephric emphysema, and one case of emphysematous pyelitis to demonstrate the value of computerized tomography (CT) in both diagnosis and patient management. The differentiation between air in the collecting system (emphysematous pyelitis), air within the parenchyma (emphysematous pyelonephritis), and air in the perinephric space (perinephric emphysema) may have significant prognostic (survival) and therapeutic (medical vs surgical) implications. Computerized tomography is currently the best method for demonstrating intrarenal air and for characterizing the location of that air (intracalyceal, intraparenchymal, perinephric, or pararenal).

3/4. Spectrum of gas within the kidney. Emphysematous pyelonephritis and emphysematous pyelitis.

    Renal emphysema is an important clinical entity that is not addressed frequently in the medical literature. The affected patients may have gas within the renal parenchyma, emphysematous pyelonephritis, or confined to the collecting system, emphysematous pyelitis. Two patients that illustrate the spectrum of this entity are described. The literature has been reviewed to determine the clinical features of each disorder and to provide a schema for diagnosis and management. Emphysematous pyelonephritis is seen primarily in diabetic patients, whereas emphysematous pyelitis is recognized most often in association with urinary tract obstruction. The diagnosis is made radiographically by demonstrating renal gas on plain abdominal roentgenography or intravenous pyelography. Location and extent of renal gas are best evaluated by computed tomographic scanning. Intraparenchymal gas usually requires nephrectomy, whereas successful therapy of gas limited to the collecting system involves medical management, with a drainage procedure when obstruction coexists.

4/4. Emphysematous renal and perirenal infection in nondiabetic patient.

    Emphysematous renal infection is a severe, rare complication of urinary tract infection associated with gas production, which frequently causes renal destruction and has a high mortality rate. It is termed emphysematous pyelitis when gas is confined to the collecting system, or emphysematous pyelonephritis if it also involves the parenchyma with or without the perirenal space. Only 7 cases of perirenal emphysema have been described previously; all were in diabetics. Here we present a rare case of gas-producing renal infection in the collecting system and perirenal tissues, in a nondiabetic patient, and discuss the management of the various types of emphysematous renal infections.
