|January 19, 2018
Summary
An 80-year-old woman with an infective subcapsular renal hematoma experienced recurrence. Renal arteriography detected a renal artery microaneurysm, which was successfully treated with embolization, improving her condition.
Area of Science:
- Nephrology
- Interventional Radiology
- Infectious Diseases
Background:
- Infective subcapsular renal hematoma is a rare condition.
- Early diagnosis and treatment are crucial for patient outcomes.
Purpose of the Study:
- To report a case of recurrent infective subcapsular renal hematoma.
- To highlight the utility of renal arteriography in identifying underlying vascular abnormalities.
Main Methods:
- A case study of an 80-year-old woman with a subcapsular renal hematoma.
- Initial treatment included percutaneous drainage and antibiotics.
- Recurrence prompted repeat drainage, antibiotics, and renal arteriography.
Main Results:
- Initial treatment led to temporary improvement, but the hematoma recurred.
- Renal arteriography revealed a renal artery microaneurysm.
- Renal artery embolization successfully treated the microaneurysm and resolved the hematoma.
Conclusions:
- Renal artery microaneurysms can complicate infective subcapsular renal hematomas.
- Renal arteriography is valuable for detecting these microaneurysms.
- Embolization is an effective treatment for renal artery microaneurysms in this context.

01:17Factors Affecting Renal Clearance: Renal Impairment
503
Renal dysfunction significantly impairs the renal clearance of drugs, leading to potential complications in drug therapy. Renal failure, which can be caused by various factors, poses a significant challenge in the elimination of drugs from the body.
One condition associated with renal failure is uremia. Uremia is characterized by impaired glomerular filtration and fluid accumulation in the body. This condition hinders the renal clearance of drugs, resulting in drug accumulation and potential...

The glomerulus and Bowman's capsule are two essential components of the nephron, which is the functional unit of the kidney. These microscopic structures play a critical role in the process of blood filtration to produce urine.
Glomerulus: Structure and Function
The glomerulus is a tiny, intricate network of capillaries located at the beginning of the nephron. It's enveloped by the Bowman's capsule and receives its blood supply from an afferent arteriole, which divides into numerous...

The glomerular filtration rate (GFR) is a critical marker of kidney function, reflecting the efficiency of filtration by the glomeruli. Renal clearance of specific substances, such as inulin or creatinine, is commonly used to measure GFR.
Renal clearance refers to the volume of plasma cleared of a specific substance, such as creatinine, per unit of time. To measure clearance, urine samples are collected over a 24-hour period during each bladder voiding, followed by a single blood sample at the...

Renal clearance is a critical parameter encompassing kidney filtration, secretion, and reabsorption processes. It is calculated using a specific equation to determine the rate at which the kidneys clear a drug.
Renal clearance is often associated with the renal glomerular filtration rate (GFR), which represents the rate at which plasma is filtered through the glomeruli in the kidney. When drug reabsorption is minimal and there is no active secretion, renal clearance is closely related to the...

3.4K
The liver plays a pivotal role in eliminating drugs and their metabolites, primarily through a process known as biliary excretion. This process involves the hepatocytes, the primary cells in the liver that generate bile. A range of transporters actively expels polar drugs or hydrophilic drug metabolites into the bile, which transports the drugs and metabolites into the small intestine. From here, they are eventually expelled from the body through feces. In some instances, the original drug or a...

01:24Renal Tubule and Collecting Duct
3.7K
The renal tubule is divided into three parts: the proximal convoluted tubule (PCT), the Loop of Henle (LOH), and the distal convoluted tubule (DCT).
Proximal Convoluted Tubule (PCT):
The PCT is the initial segment of the renal tubule, extending from the Bowman's capsule that encloses the glomerulus. Its convoluted structure and microvilli-lined cells increase the surface area for reabsorption. The PCT reabsorbs glucose, amino acids, sodium, and water from the filtrate, ensuring essential...
