What causes urine stream splitting?

A common cause of split urine stream is chronic prostatitis. Due to functional obstruction of the urethra caused by chronic prostatitis, symptoms may include hesitancy, incomplete bladder emptying, split urine stream, and narrowed urinary stream. If split urine stream persists over a long period, a routine urine test is recommended. Additionally, a prostate fluid examination can be performed to check for urinary tract infection or prostatitis. For patients diagnosed with chronic prostatitis, oral tamsulosin combined with traditional Chinese medicines that promote blood circulation and remove blood stasis—such as Qianlie Shu Tong or Qianlie Bi Tong—can help reduce prostate edema, relax the urethral sphincter, and thereby improve the symptom of split urine stream.
