Itchy urine is also commonly known as urethral itching, most of which is caused by urethra-related diseases, and the degree of itching in patients can be mild or severe, mainly determined by the severity of the condition. The common causes include urethral inflammation, urethral stones, urethral strictures, prostate-related diseases, etc. Detailed examinations such as routine blood tests, routine urine tests, ultrasounds, etc. are needed to clarify the diagnosis, and if necessary, cystoscopy and urethroscopy should also be performed, and only when the cause is clear can targeted treatment be carried out, such as antibacterial and anti-inflammatory treatment for patients with inflammation, and surgical intervention for patients with stones and strictures. If the cause is removed, the patient’s urethral itching will disappear on its own.
