Patchy renal ischemia

Acute Renal Failure with Severe Loin Pain and Patchy Renal Ischemia After Anaerobic Exercise.-... 

In 1982, we classified exercise-related acute renal failure into two types myoglobinuric acute renal failure, as had previously been reported, and non-myoglobin-related acute renal failure (exercise-induced acute renal failure). In 2002, the latter was named ALPE (Acute renal failure with severe Loin pain and Patchy renal ischemia after anaerobic Exercise) [4]. The term acute kidney injury (AKI) has recently been proposed as a patho-physiologically more correct alternative to the term acute renal failure. Therefore, exercise-induced acute renal failure in this book may be replaced by exercise-induced acute kidney injury. 

Minimum rhabdomyolysis—non-myoglobinuric acute renal failure due to exercise-induced acute renal failure—ALPE (acute renal failure with severe loin pain and patchy renal ischemia after anaerobic exercise) after sprint, short track event such as 200-m race, etc. 

The other type is non-myoglobinuric acute renal failure, in which intense exercise over a short period of time, such as sprinting, causes minimal rhabdomyolysis without myoglobinuria, i.e., acute renal failure syndrome with severe loin pain and patchy renal vasoconstriction [2]. A recent study showed that anaerobic exercise caused this syndrome, and proposed that Acute renal failure with severe Loin pain and Patchy renal ischemia after anaerobic Exercise (ALPE) (exercise-induced acute renal failure) was a new type of acute renal failure syndrome [4]. 

The First Patient in Whom Wedge-Shaped Patchy Renal Ischemia was Demonstrated... 

We performed delayed CT after the administration of contrast medium in 11 patients with both ALPE and renal hypouricemia. In 10 of the 11 patients, patchy renal ischemia was noted [4], suggesting that renal ischemic conditions after anaerobic exercise were similar regardless of the presence or absence of renal hypouricemia.
