The causes of painful urination include urinary tract infection, prostatitis, urethral stones, drug side effects, and tumors.
1. Urinary tract infection is one of the common causes of painful urination. The infection can occur in any part of the urinary system, such as kidneys, ureters, bladder, urethra and so on. In addition to painful urination, symptoms such as fever, frequent urination, and lower back and abdominal pain can also occur.
2. Prostatitis can cause burning, stinging and discomfort in the urethra and painful urination if the infection is severe.
3. Urethral stones may rub and irritate the urethral mucosa, which can cause painful urination.
4. Certain medications, such as those used in cancer treatment and some antibiotics, may produce painful urination as a side effect.
5. Tumors in the urethra can damage the urethral mucosa, resulting in painful urination, which may be accompanied by hematuria.
Patients with painful urination are advised to seek medical treatment in time for detailed examination and treatment after clear diagnosis.
