Pain in the glans penis when urinating

The phenomenon of stinging in the glans penis when urinating is urinary pain, and the most likely cause is urethritis. Urethritis is very common in clinical practice, but it is difficult to determine whether a symptom is caused by urethritis. We need to have a comprehensive understanding of the situation of urethritis, and then make a comprehensive judgment based on our own situation, so as to determine whether it is caused by urethritis. Let's take a look at the situation of urethritis.

Clinical manifestations

Frequent urination, painful urination, urgent urination and hematuria. In the acute phase, males may have urethral secretions, which are mucous at first and then purulent. Females have less secretions. When the disease becomes chronic, it manifests as urethral stinging and discomfort during urination. The urethral secretions decrease and become a thin syrup. In acute attacks, there is dull pain in the suprapubic area and perineum, and the urethral opening is red and has secretions.

Causes

Common causes of urethritis are as follows: ①Urethra injury: abrasion of the urethral mucosa caused by urethral instrument examination can damage the defense function of the urethral mucosa and lead to bacterial infection; ②Urethra foreign body: foreign body or urethral stones inserted from the outside can cause urethral infection if left there for a long time; ③Urethra obstruction: such as narrow foreskin opening, narrow urethral opening, narrow urethra, posterior urethra ④ Valves, urethral tumors, female hymen umbrellas, fusion of the hymen at the urethral orifice, etc., due to poor urination, urine accumulates in the urethra and can cause urethral infection; ④ Inflammation of adjacent organs, such as prostatitis, seminal vesiculitis, vaginitis or cervicitis, can spread to the urethra, which is often a stubborn lesion of chronic posterior urethritis; ⑤ Often related to sexual life, unclean sexual life can easily cause urethral infection.
