1. Hematuria

2. Hyperglycemia

Introduction: Hematuria is the presence of red blood cells (RBCs) in the urine. In microscopic hematuria, the urine appears normal to the naked eye, but examination with a microscope shows a high number of RBCs. Gross hematuria can be seen with the naked eye—the urine is red or the color of cola.

Hematuria

The most common causes includes: Benign Prostatic Hyperplasia Kidney stones and bladder stones Kidney Diseases Medications (e.g., quinine, rifampin, phenytoin) Prostate infection or inflammation (prostatitis) Trauma (e.g., a blow to the kidneys) Tumors and/or cancer in the urinary system

Causes:

Urinary tract blockages Viral infections of the urinary tract and sexually

transmitted diseases, particularly in women

There are rare diseases and genetic disorders that also cause hematuria. Some of these are:

Sickle cell anemia (inherited blood disorder) Systemic lupus erythematosus (lupus; chronic

inflammatory disorder of connective tissue) von Hippel-Landau disease (hereditary disease in

which benign tumors form on the spinal cord, kidneys, testicles, and other organs)

Causes Contd.

Blood in the urine is the main signSymptoms include: Abdominal pain Decreased urinary force, hesitancy, incomplete voiding Fever Frequent urination (polyuria) Pain during urination (dysuria) Pain in the flank or side Urinary urgency

Signs & Symptoms

Dipstick Test: Physician performs this in a chemically treated strip by taking a sample of mid-stream urine. The chemical changes color if blood in the urine. Cystourethroscopy or Cystoscopy:

is performed with local anesthesia, and a small, rigid or flexible fiber-optic instrument is inserted into the urethra. The physician can visually inspect the urethra, bladder, and prostate through the cystoscope. The procedure takes about 10 minutes.

Hematuria Tests

Intravenous pyelogram (IVP) :It is a special x-ray procedure in which a colorless dye containing iodine is injected into a vein in the patient's arm. The dye collects in the urinary system and provides enhanced contrast for a series of x-rays taken over 30 minutes. Hematuria Differential DiagnosisWhen no specific cause can be found, bladder and kidney stones, cancer, and other life-threatening diseases can be ruled out. Men over the age of 50 with no clear diagnosis should have a yearly prostate specific antigen (PSA) test to screen for prostate cancer.

Hematuria test contd..

Treatment ranges from antibiotic therapy to surgery, depending on the underlying cause. Benign Prostatic hyperplasia: Treated in many

ways. Diet restricting on foods and beverages and counter medications. If it is worse, surgical removal of all part or the gland may be recommended.

Kidney & Bladder stones: Typically require procedures that remove or break up the stones, as well as measures to prevent their recurrence.

Hematuria treatment contd.

Kidney disease is treated according to

diagnosis. In severe cases, dialysis may be necessary.

Medications (e.g., quinine, rifampin, phenytoin) that cause hematuria are discontinued

Trauma-induced hematuria (e.g., a blow to the kidneys) is treated according to the severity of the injury, ranging from bed rest and close clinical observation to surgical repair or, in extreme cases, removal of the damaged tissue or organ.

Hematuria Treatment contd.

Cancerous tumors found in the kidney,

ureters, prostate, or bladder may be treated with radiotherapy, chemotherapy, and surgery.

Urinary tract blockages are treated with correction or removal of the blockage.

Viral infections of the urinary tract and sexually transmitted diseases (STDs), particularly in women, are treated with medication.

Hematuria Treatment Contd.

Hyperglycemia, or high blood glucose (sugar), is a serious health problem for those with diabetes. Hyperglycemia develops when there is too much sugar in the blood. In people with diabetes, there are two specific types of hyperglycemia that occur:Fasting hyperglycemia is defined as a blood sugar greater than 90-130 mg/dL (milligrams per deciliter) after fasting for at least 8 hoursPostprandial or after-meal hyperglycemia is defined as a blood sugar usually greater than 180 mg/dL. In people without diabetes postprandial or post-meal sugars rarely go over 140 mg/dL but occasionally, after a large meal.

Hyperlycemia

The main causes of hyperglycemia are: Excess supply A decrease in physical activity Lack of insulin and / or oral medications

(dosing error) Physical stress (illness, surgery, infection,

etc..) Or psychological (bereavement, new job, moving, etc..)

Taking certain medications (like cortisone)

Causes

Hyperglycemia symptoms are the following: Fatigue and sleepiness Frequent urination Increased thirst Excessive hunger Thinning Blurred vision Infections Slow healing of wounds

Symptoms of hyperglycemia

Dry skin and itching Irritability Presence of ketones in the urine Nausea, vomiting Abdominal Fruity breath Confusion Rapid breathing

Contd.

In the presence of dymp yomd of

hyperglycemia, the diabetic should follow the next hyperglycemia treatment:

Measure the blood glucose If blood glucose is less than 14mmol / L,

the person with type 1 diabetes must check for ketones in the urine or blood

Drink plenty of water Identify the cause

Hyperglycemia Treatment

Correct the cause, if possible Contact a doctor or go to the emergency: If

blood glucose exceeds 20 mmol / L ; If the presence of ketones in the urine is moderate to high; It is impossible to keep ingested liquids
