“…The volume of the perirenal hematoma formed was measured, by ultrasound, three times immediately after the biopsy procedure and was calculated using the following formula: V = 4/ 3 9 p 9 Rap 9 Rml 9 H, where V = volume, Rap = anteroposterior radius, Rml = mediolateral radius and H = height. 11 The final volume was the result of the average between three measurements. At 3 h, 12 h and 7 days after the procedure, ultrasonography was obtained of each patient and no dropouts were observed.…”

“…It has been reported that mean hematoma volume due to infective causes was 143 mm 3 , and was less than that caused by other diseases [5]. Because the volume of hematoma in our case was obviously larger than this, infection could not have been the cause, and therefore, we should have investigated for another cause of hematoma earlier.…”

“…Because urine and drain fluid culture both yielded E. coli, we suspected that the infection may have developed as the pathogens ascended to the kidneys via the ureters. Some reports have described infectious causes of subcapsular renal hematoma [1,[3][4][5], but there are few reports of subcapsular renal hematoma due to renal artery aneurysm and repeated retrograde infection.…”

An 80-year-old woman was admitted to the hospital complaining of loss of appetite. 10 days earlier, her oral intake gradually decreased with no other specific symptoms, such as abdominal pain, nausea, vomiting, headache, or low back pain. Abdominal computed tomography (CT) scan revealed a left subcapsular renal hematoma. We suspected infective subcapsular renal hematoma, so percutaneous needle aspiration and drainage were performed. Intravenous sulbactam-ampicillin was started immediately. On day 9 after admission, repeat CT scan revealed the subcapsular hematoma had reduced in size. The drain was removed, and intravenous antibiotics were discontinued. Follow-up CT scan on day 21 revealed increased subcapsular renal hematoma size. The patient also had high fever. Suspecting recurrence of infective subcapsular renal hematoma, we repeated the drainage of the hematoma and restarted intravenous antibiotics. Renal arteriography showed a renal artery microaneurysm and her condition improved with renal artery embolization. Renal arteriography was useful for detecting renal artery microaneurysm in infective subcapsular renal hematoma that did not resolve after antibiotic treatment and drainage.

“…5 In contrast to the other authors, Mao et al reported 27.1% coagulation abnormality, 13.5% simple renal cysts, 13.5% (which three were associated with CA), RCC 11.1%, 11.1% ruptured abdominal aorta aneurysm, 11.1% adrenal tumors (three of them associated with CA), 8.6% polycystic kidney disease (one of them associated with CA), 6.2% idiopathic, 7.4% AML, 2.4% renal vascular disease and 1.2% infection. 6 Ultrasound (USG) is the first choice in imagining modalities. But this imagining modality is highly dependent to the operator and small tumours may be misdiagnosed.…”
