What causes split urine stream and pain during urination in men?

Male urine stream splitting and painful urination may be caused by various factors. It could result from urethritis, as acute inflammation within the urethra causes local congestion and swelling, obstructing urine flow and leading to urine stream splitting; the inflammatory irritation can also cause pain during urination. Chronic prostatitis is another common cause—local congestion in the prostate compresses the urethra, resulting in urine stream splitting and painful urination. Urethral stones and urethral polyps may also lead to these symptoms, as they block urine outflow and irritate the local mucosa. Bladder conditions such as cystitis can also cause painful urination, often accompanied by urine stream splitting. Men experiencing urine stream splitting and painful urination should seek timely medical attention to determine the underlying cause and receive targeted treatment.
