What causes blood in a man's urine? Discovering blood in urine can be alarming. Experts note that visible hematuria indicates a relatively serious condition. The causes can vary, and it is advisable to seek a comprehensive examination at a reputable hospital for timely treatment.
Causes can be summarized into three main categories:
1. Urinary Tract Infection (UTI)
Renal hematuria originates from the glomeruli, clinically presenting as simple hematuria or hematuria with proteinuria. It commonly occurs in patients with UTIs. Inadequate treatment, recurrent infections, or mismanagement can prevent effective control of the condition, ultimately leading to uremia.Increased permeability of capillary walls can cause hematuria; lesions in adjacent organs affecting the urinary tract may also lead to blood in urine.
2. Cystitis
Cystitis predominantly affects the bladder mucosal epithelium, which grows rapidly and is prone to surface ulceration and bleeding. Consequently, the most common symptom of cystitis is painless, gross hematuria visible to the naked eye—a distinctive urinary abnormality signaling bladder cancer.
3. Prostatic Hyperplasia
Hematuria is a common symptom of prostatic hyperplasia, often presenting as increased urinary frequency, incomplete voiding, and a shortened urine stream. Occasionally, it may also manifest as blood in urine.
4. Renal Hemorrhage
Hematuria may result from increased permeability of capillary walls or lesions in adjacent organs affecting the urinary tract.
3. Prostatic Hyperplasia
Hematuria is a common symptom of benign prostatic hyperplasia (BPH), typically presenting as increased urinary frequency, incomplete voiding, and a weakened urine stream. Occasionally, hematuria may also occur.This occurs because as the prostate enlarges, the capillaries within its mucosal lining become congested, dilated, and twisted. When stretched by bladder contractions or the enlarged prostate, these capillaries rupture, leading to hematuria.
What causes blood in a man's urine? After reading the expert explanation, you should now understand. A friendly reminder: Be attentive to your health in daily life. If you notice any minor symptoms of illness, seek timely detection and treatment.
