If one has an itching sensation in his urethra when urinating and at night but have no discharge whatsoever what could be the problem?

Itching (pruritus) in the urethra during urination and at night, without any discharge, can have several possible causes:

1. Urinary Tract Infection (UTI): UTIs can cause inflammation and irritation of the urinary tract, including the urethra. While discharge is a common symptom of UTIs, it is not always present. In some cases, only itchiness or burning may occur.

2. Urethritis: Urethritis is a condition characterized by inflammation of the urethra. It can be caused by various factors, including sexually transmitted infections (STIs), bacterial infections, or chemical irritants. Urethritis can lead to itching and discomfort during urination.

3. Prostatitis: Prostatitis, an inflammation of the prostate gland, can cause various urinary symptoms, including itching or pain in the urethra. Prostatitis often affects older men and can be caused by infections or inflammation.

4. Allergic Reaction: An allergic reaction to certain substances, such as soaps, detergents, or spermicides, can cause itching and irritation in the urethra and surrounding areas.

5. Skin Conditions: Some skin conditions, such as eczema or psoriasis, can affect the skin around the urethra and cause itching.

6. Diabetes: Poorly controlled diabetes can cause inflammation and increased urination, which can contribute to itching in the urethra.

If you are experiencing persistent itching in the urethra, it's essential to see a healthcare provider for evaluation and proper diagnosis. The doctor may perform tests such as urine analysis and culture to identify any underlying infections. Based on the findings, appropriate treatment will be recommended. Self-treatment is not advisable, as incorrect diagnosis and management can lead to complications.
