Summary
Exercise-induced hematuria (blood in urine) is common, especially with timed runs. If hematuria persists beyond two weeks, underlying kidney disease is likely, not just functional.
Area of Science:
- Nephrology
- Sports Medicine
- Urology
Background:
- Exercise-induced hematuria (EIH) is a known phenomenon.
- Previous literature suggests EIH duration ranges from hours to three days.
- The role of exercise intensity versus duration in EIH is not fully elucidated.
Purpose of the Study:
- To investigate the incidence and duration of EIH in healthy adults.
- To explore the relationship between exercise intensity (timed vs. untimed run) and EIH.
- To identify potential risk factors and predictors for prolonged EIH.
Main Methods:
- Healthy participants (age 20-50) with normal baseline urine sediment were recruited.
- Urine sediment was analyzed before and after a 5km run.
- Participants completed the run either within an allotted time or without a time limit.
Main Results:
- A timed 5km run resulted in a 12% incidence of EIH, significantly higher than an untimed run (1.3%, p < 0.001).
- Younger participants (<30 years) showed a higher incidence of EIH (p=0.019).
- While 81% cleared hematuria within 3 days, 7% persisted beyond 7 days, and 3 individuals beyond 14 days, with underlying glomerular diseases identified.
Conclusions:
- EIH incidence is significantly influenced by exercise intensity, particularly timed efforts.
- EIH can persist for up to two weeks.
- Persistent hematuria beyond 14 days suggests an underlying renal pathology, warranting further investigation.

2.5K
Urinalysis is a widely used diagnostic test that analyzes urine's physical, chemical, and microscopic characteristics. Healthcare providers use it to detect and monitor various health conditions, including renal disease, urinary tract infections (UTIs), diabetes, and metabolic or systemic disorders.Components of UrinalysisUrinalysis consists of three primary components: physical, chemical, and microscopic examination. Each provides unique insights into the urine sample and, by extension, the...

2.2K
DialyzersA hemodialysis (HD) dialyzer is a plastic cartridge containing thousands of parallel hollow fibers, which serve as semipermeable membranes. These fibers are typically made from cellulose-based or other synthetic materials. During HD, blood is pumped into the top of the cartridge and distributed among these fibers. Simultaneously, dialysis fluid, known as dialysate, is introduced into the bottom of the cartridge, bathing the outside of the fibers. Across the semipermeable membrane,...

23
A hemorrhagic stroke develops when a cerebral blood vessel ruptures, allowing blood to escape into the surrounding brain tissue, as in intracerebral hemorrhage (ICH), or into the subarachnoid space, as in subarachnoid hemorrhage (SAH). Because the skull is a rigid compartment, the sudden presence of extravascular blood rapidly increases intracranial pressure and compresses adjacent neural structures, leading to immediate tissue injury and impaired cerebral perfusion.Mass Effect and Primary...

01:24Inflammatory Response II: Inflammatory Exudate and Tissue Repair
8.4K
The immune system's inflammatory response destroys the invading pathogen, permitting the tissue to heal. The changes during the cellular and vascular stages allow exudate formation at the site of inflammation. The inflammatory exudate released from the wound has high protein content and a specific gravity above 1.020.
The typical wound exudate is odorless, transparent, straw-colored, thin, and watery. Exudate, however, can differ depending on the state of wound healing. Likewise, the...

Hyperglycemia is an abnormally high blood glucose level. It is diagnosed by fasting glucose ≥126 mg/dL, 2-hour oral glucose tolerance test (or OGTT) ≥200 mg/dL, random glucose ≥200 mg/dL with symptoms, or HbA1c ≥6.5%. However, HbA1c results may be unreliable in certain conditions, such as anemia or hemoglobinopathies, and the diagnosis should be confirmed unless classic symptoms are present. Postprandial hyperglycemia is typically considered significant when glucose...

01:26Regulation of Water Output
2.0K
The human body predominantly expels water through the urinary system. On average, an individual generates around 1.5 liters of urine each day. This amount can fluctuate based on how well a person is hydrated, but a critical minimum quantity of urine must be produced to ensure the body's proper functioning. Daily, the kidneys remove 600 to 1200 milliosmoles of dissolved substances, effectively excreting excess minerals and water-soluble toxins such as creatinine, urea, and uric acid from the...
