An enlarged prostate, also known as prostate hyperplasia, does not usually cause itching, but can lead to urethral itching if there is an infection or if it is accompanied by a condition such as urethritis or loss of urethra. The main symptom of prostate enlargement is frequent urination, especially at night, and is accompanied by symptoms such as difficulty in urination, thinning of the urinary line, and urinary bifurcation, which does not usually lead to urethral itching. As prostate enlargement progresses, patients can develop urinary retention and even recurrent urinary tract or prostate infections, which can lead to frequent urination, urinary urgency, urinary pain, and urethral itching. If prostate enlargement is accompanied by other diseases, such as urethritis and urethral injury can also lead to itchy urethra. Patients with prostate hyperplasia have itchy urethra, it is recommended to go to the hospital, improve the relevant examination to confirm the diagnosis and then give treatment.
