No suspicion, no disease! renal infarction: case series.

Abdominal and flank pain with sudden onset is one of the most common patient presentations to emergency departments (ED). Renal infarction is a rare cause of abdominal and flank pain. Usually the symptoms of renal infarction are nonspecific, so the diagnosis is frequently missed or delayed. Especially if a patient has a disease such as nephrolithiasis and pyelonephritis, the possibility of delay or a misdiagnosis will increase. This may lead to irreversible loss of renal function. Diagnosis requires high degree of suspicion. In other words, ‘no suspicion, no disease’. Renal infarction was first described in 1940 by Hoxie and Kogan. Although it is uncommon, it is responsible for considerable morbidity and mortality. In this case series, we aim to increase awareness of this condition and decrease the delay and misdiagnosis of renal infarctions.
