What causes foamy urine with splitting in men?

Foamy urine with splitting in men may be caused by various factors. Physiological causes, such as prolonged urine retention, can lead to concentrated urine, resulting in split urine stream and foaming during urination. Pathological causes include inflammatory conditions like urethritis and prostatitis, which can cause local congestion and swelling in the urethra, impairing urine flow and introducing inflammatory substances into the urine, thereby leading to a split stream and foam. Additionally, conditions such as urinary tract infections, cystitis, nephritis, and diabetes may alter urine composition, causing these symptoms. If accompanied by other abnormal signs, timely medical evaluation and appropriate treatment are recommended.
