Etiology

  • Urinary tract infections (UTIs): UTIs are the most common cause of hematuria, especially in women.
  • They occur when bacteria enter the urethra and travel up to the bladder. UTIs can cause irritation and inflammation of the bladder lining, which can lead to bleeding.
  • Kidney infections: Kidney infections are less common than UTIs, but they can also cause hematuria. Kidney infections occur when bacteria travel from the urethra or bloodstream to the kidneys. Kidney infections can cause inflammation and damage to the kidneys, which can lead to bleeding.
  • Kidney stones: Kidney stones are hard deposits of minerals that form in the kidneys. They can irritate the urinary tract and cause bleeding.
  • Enlarged prostate (benign prostatic hyperplasia or BPH): BPH is a common condition in older men that causes the prostate gland to enlarge. An enlarged prostate can irritate the urethra and cause bleeding.
  • Injury to the urinary tract: Injury to the kidneys, bladder, or urethra can cause bleeding. This type of hematuria is more likely to occur after a car accident, fall, or other trauma.
  • Certain medications: Some medications, such as blood thinners and aspirin, can increase your risk of bleeding, including hematuria.
  • Cancer: In some cases, hematuria can be a sign of cancer of the urinary tract, including cancer of the kidneys, bladder, or urethra. However, hematuria is more likely to have a less serious cause.

If you experience hematuria, it's important to see a doctor to determine the cause and get treatment. Early diagnosis and treatment can help prevent complications.

 

Chief Complaint: Hematuria

Pivotal Assessment Findings
       

*

A biopsy alone cannot definitively determine muscle invasion in bladder cancer. However, the biopsy results in combination with other tests and procedures provide strong clues for the doctor. Here's how they work together:

Biopsy:

  • Tissue Depth: The depth from which the biopsy is taken gives an initial indication. A deeper sample increases the possibility of muscle involvement.
  • Pathology Report: The pathologist examines the biopsied tissue under a microscope. While they can't directly see muscle layers, they can look for:
    • Cellular Changes: Certain changes in the cells might suggest deeper invasion.
    • Presence of Lymphovascular Invasion: If the biopsy shows cancer cells within blood or lymph vessels, it raises suspicion for spread beyond the initial site, potentially including muscle.

Cystoscopy:

During a cystoscopy, the doctor visually inspects the bladder lining. While not definitive, some features of the tumor can suggest muscle invasion:

  • Size and Appearance: Larger tumors or those with irregular borders are more likely to involve deeper tissues.
  • Location: Tumors located closer to the ureteral openings (tubes draining urine from kidneys) have a higher chance of muscle involvement.

Imaging Tests:

Imaging tests like CT scans or MRI scans can provide a more detailed view of the bladder wall and surrounding tissues. While they can't directly see muscle layers either, they can help identify:

  • Wall Thickness: Thickening of the bladder wall can be a sign of muscle invasion.
  • Adjacent Organ Involvement: If the tumor appears to involve nearby structures like the prostate or uterus, it suggests muscle invasion.

Putting it Together:

The doctor will consider all the information from the biopsy (depth, pathology), cystoscopy (visual findings), and imaging tests (wall thickness, spread) to determine the likelihood of muscle invasion. In some cases, additional tests like cystoscopy with transurethral resection of bladder tumor (TURBT) might be needed. During TURBT, a larger tissue sample is removed for analysis, providing a clearer picture of muscle involvement.

When Muscle Invasion is Suspected:

If muscle invasion is suspected based on the combined findings, it significantly impacts the stage and treatment plan for bladder cancer. Early detection and treatment of muscle-invasive bladder cancer is crucial for better outcomes.

Causes of nephritic syndrome can include:

Treatment for nephritic syndrome depends on the underlying cause. It may include medications to reduce inflammation, control blood pressure, and remove excess fluid from your body. In some cases, dialysis or a kidney transplant may be necessary.

 

  

 

  • Medical history: This will involve questions about your symptoms, any medications you are taking, and your family history.
  • Physical exam: This may include a urinalysis to check for blood cells, white blood cells, and other abnormalities in your urine. A doctor may also perform a digital rectal exam (DRE) to check for an enlarged prostate.
  • Imaging tests: An ultrasound of the kidneys and bladder can be used to look for abnormalities such as kidney stones or tumors. X-rays or CT scans may also be used.
  • Cystoscopy: This is a procedure where a thin tube with a camera is inserted into the urethra to look for abnormalities in the bladder.

The specific tests that will be done will depend on your individual situation.

Here are some of the things that a doctor may be looking for when trying to determine the cause of hematuria:

  • Urinary tract infection (UTI): This is a common cause of hematuria, especially in women. UTIs are caused by bacteria that enter the urethra and travel up to the bladder.
  • Kidney stones: These are hard deposits of minerals that form in the kidneys. They can irritate the urinary tract and cause bleeding.
  • Enlarged prostate: This is a common condition in older men. An enlarged prostate can put pressure on the urethra and cause bleeding.
  • Cancer: Cancer of the bladder, kidneys, or urethra can cause hematuria. However, hematuria is a more common symptom of other conditions.
  • Kidney disease: There are a number of kidney diseases that can cause hematuria.
  • Injury: Injury to the kidneys, bladder, or urethra can cause bleeding.
  • Medications: Certain medications, such as blood thinners and aspirin, can increase your risk of hematuria.

If you are experiencing hematuria, it is important to see a doctor to determine the cause. Early diagnosis and treatment can help prevent complications.
