Urinblødning

Urinblødning, also known as hematuria, refers to the presence of blood in the urine. It can manifest in two primary forms: macroscopic hematuria, where the urine appears visibly red or pink due to blood, and microscopic hematuria, where blood is only detectable through laboratory analysis. Macroscopic hematuria can be painless or accompanied by pain, depending on the underlying cause.

Various factors can lead to urinblødning. Common causes include urinary tract infections (UTIs), kidney stones, and bladder stones. Inflammation of the urinary tract or bladder, known as cystitis or urethritis, can also result in bleeding. Trauma to the kidneys or urinary tract can also cause blood in the urine.

More serious underlying conditions can also present with hematuria. These include kidney disease, such as glomerulonephritis, and tumors in the kidney, bladder, or prostate. Certain medical conditions like sickle cell anemia and inherited kidney disorders can also be responsible. Some medications, including blood thinners, can also contribute to the presence of blood in urine.

Diagnosis of urinblødning typically involves a physical examination, a review of medical history, and urine tests. Further investigations may include blood tests, imaging studies like ultrasound or CT scans, and sometimes a cystoscopy, a procedure where a small camera is inserted into the bladder to visualize its lining. Treatment depends entirely on the identified cause.
