Emphysematous urinoma as a complication of emphysematous pyelitis in a healthy adult male.

Emphysematous pyelitis and urinomas are independently rare conditions. The former is a severe necrotizing infection involving the renal collecting system, the latter an encapsulated collection of urine in the perinephric or paraureteral space. An unusual case of emphysematous urinoma complicating emphysematous pyelitis in a healthy male adult is presented in this study.
