Summary
A case of non-traumatic perirenal hematoma in a 56-year-old woman was successfully treated with transcatheter arterial embolization. This minimally invasive procedure effectively stopped bleeding from a renal artery branch, resolving back pain without complications.
Area of Science:
- Nephrology
- Interventional Radiology
- Vascular Surgery
Background:
- Non-traumatic perirenal hematoma is a rare condition often presenting with flank pain.
- Diagnosis typically involves advanced imaging like computed tomography (CT) and angiography.
- Management strategies range from conservative care to interventional procedures.
Observation:
- A 56-year-old woman presented with acute left back pain.
- CT scan revealed a left perirenal hematoma.
- Selective renal arteriogram identified minor contrast leakage from a renal artery branch.
Findings:
- Transcatheter arterial embolization (TAE) was performed to occlude the bleeding vessel.
- The embolization procedure was technically successful, halting contrast extravasation.
- Post-embolization follow-up showed no recurrence or complications.
Implications:
- TAE is a safe and effective treatment for non-traumatic perirenal hematoma caused by arterial leakage.
- Minimally invasive embolization offers a valuable alternative to surgical intervention.
- Review of 149 literature cases provides broader context for understanding this rare condition.

01:29Acute Kidney Injury II: Pathophysiology
Acute kidney injury (AKI) causes are categorized into three primary categories based on the location of the injury: prerenal, intrarenal (or intrinsic), and postrenal causes. This classification guides clinical management and illustrates how different pathways can impair kidney function.Etiology and Pathophysiology of Acute Kidney Injury1. Prerenal causesEtiology: Prerenal Acute Kidney Injury, the most common type, occurs when reduced blood flow to the kidneys decreases filtration capacity...

Accurate diagnosis and effective prevention are critical in managing Acute Kidney Injury (AKI), which is linked to high mortality rates ranging from 10% to 80%. Timely recognition of at-risk patients and careful monitoring can significantly reduce the likelihood of kidney damage.Diagnostic Assessments:The diagnostic process starts with a comprehensive medical history to identify prerenal, intrarenal, and postrenal causes.Prerenal causes, such as dehydration, hypotension, or blood loss, should...
01:22Acute Kidney Injury I: Introduction
Introduction:Acute Kidney Injury (AKI) describes a swift decrease in kidney function occurring over hours to days, characterized by the kidneys' failure to remove waste products from the bloodstream. This leads to dangerous complications like metabolic acidosis, fluid overload, and electrolyte imbalances, such as hyperkalemia, which can cause life-threatening arrhythmias. AKI is common in both hospital and outpatient settings, often triggered by dehydration, sepsis, or exposure to nephrotoxic...
01:28Acute Pyelonephritis II: Diagnostic Studies and Management
Introduction:For diagnosing acute pyelonephritis, a comprehensive patient history is collected to identify symptoms such as dysuria, frequent or urgent urination, flank pain, or costovertebral angle (CVA) tenderness that may suggest a kidney infection.Physical ExaminationDuring the physical examination, CVA tenderness is assessed. This involves gentle percussion over the costovertebral angle, where tenderness often indicates a kidney infection.Diagnostic TestsUrinalysis: Used to identify white...
