“…However, in our study, “no hematuria” was significantly associated with the occurrence of RI. One reason could be that urolithiasis is a common disease in the majority of patients complaining of flank pain, and hematuria is very common in patients with urolithiasis, so hematuria may not be a reliable predictor of RI [ 32 – 34 ]. Also, because RI-related structural kidney damage can take several hours to occur, hematuria may not be detected in the urinalysis at the initial presentation in the ED [ 12 , 21 ].…”

Objectives Flank pain is a common symptom in the emergency department and can be caused by a variety of diseases. Renal infarction (RI) is a very rare disease, and many RI patients complain of flank pain. However, there is no definitive predictor of RI when patients complain of flank pain. This study aimed to identify the clinical factors for predicting RI in patients with flank pain. Methods This retrospective single-center study was conducted on patients complaining of flank pain from January 2016 to March 2020 at a South Korean tertiary care hospital. Exclusion criteria included patients who did not undergo contrast-enhanced computed tomography, age < 18 years, and trauma. Demographic and laboratory data were obtained from medical records. Logistic regression analysis was conducted to identify predictors of RI occurrence. Results In all, 2,131 patients were enrolled, and 39 (1.8%) had RI. From a multivariable logistic regression analysis, an age ≥ 65 years (odds ratio [OR], 3.249; 95% confidence interval [CI], 1.366–7.725; p = 0.008), male sex (OR, 2.846; 95% CI, 1.190–6.808; p = 0.019), atrial fibrillation (OR, 10.386; 95% CI, 3.724–28.961; p < 0.001), current smoker (OR, 10.022; 95% CI, 4.565–22.001; p < 0.001), and no hematuria (OR, 0.267; 95% CI, 0.114–0.628; p = 0.002) were significantly associated with the occurrence of RI. Conclusions Five clinical factors, i.e., age ≥ 65 years, male sex, atrial fibrillation, current smoker, and no hematuria, were significantly associated with the occurrence of RI in patients with flank pain.

“…In the constellation of symptoms, most patients are initially diagnosed with either urethral stones or gastrointestinal issues. Renal infarctions were not among the initial differential diagnoses in the 42 cases, despite them actually being renal infarcts [4]. This often leads to delayed diagnosis with resultant complications.…”

“…Cases of renal infarction are important to highlight as there is a need to include renal infarction in our differentials while dealing with patients presenting with the right symptoms. Various studies have shown that the majority of cases present with abdominal and flank pain as well as with nausea and vomiting [2][3][4]. In the constellation of symptoms, most patients are initially diagnosed with either urethral stones or gastrointestinal issues.…”

Acute renal infarction, presenting with nonspecific symptoms, such as abdominal pain, nausea, vomiting, and hematuria, can lead to delayed diagnosis due to similarities with other medical conditions. Computed tomography with IV contrast is used to diagnose renal parenchymal infarction, treated through surgical, percutaneous interventions, and anticoagulation therapy. Investigation for the infarction source is crucial, particularly in the absence of prior cardiac issues, necessitating heart rhythm monitoring and an echocardiogram to evaluate paroxysmal atrial fibrillation (PAF) and intracardiac thrombus, respectively. Renal infarction may elevate blood pressure due to renin release, recommending medications like angiotensin-converting enzyme inhibitors/angiotensin receptor blockers. We present a case of renal infarction due to PAF with a concomitant intracardiac thrombus.
