The split urine can generally be divided into physiological and pathological, physiological and bladder pressure is related, pathological and acute urethritis, prostatitis and other diseases. 1. Physiological factors: long time without urination, may lead to urine accumulation in the bladder, resulting in excessive bladder pressure, so that the urethral opening temporary change, the phenomenon of urine divergence, is generally a normal phenomenon, without special treatment. 2. Acute urethritis: usually due to pathogenic microbial infection caused by inflammatory lesions, due to inflammation stimulation will lead to urethral swelling bleeding, thus appearing the phenomenon of urine divergence. 3. prostatitis: the pathogenesis of this disease is not clear, may be associated with pathogenic bacteria pathogen infection and other factors, the occurrence of prostatitis will lead to glandular tissue congestion, edema, so that the volume of the prostate gland increases, compression of the urethra, urinary resistance increased, thus appearing in the phenomenon of urine divergence. When there is a divergence of urine, it may also be related to other diseases, based on a symptom alone, can not determine the specific cause, it is recommended to go to the regular hospital in a timely manner for medical examination and treatment.
