The symptom of 33 years old urinary divergence for many years is not a normal phenomenon; it may be related to the possibility of urethral stenosis, urinary tract infection and prostatitis and other diseases. 1. Urethral stenosis: patients with urethral or posterior urethral stenosis or scarring of the urethral orifice due to chronic inflammation will lead to the inability of urine to be discharged smoothly, which in turn will lead to the symptom of urinary divergence. 2. Urinary tract infections: such as urethritis, during an acute attack, can lead to frequent urination, urinary urgency, urinary pain and urinary diversion and other symptoms. 3. Prostatitis: The symptoms of this disease are dominated by urinary discomfort and localized pain. Patients may experience discomfort such as urine splitting, burning, frequent urination and urgency. Such symptoms may also be associated with other diseases such as stone disease; it is recommended to seek medical attention as soon as possible for timely treatment.
