Peeing hard in order to pee out may be due to benign prostatic hyperplasia, urinary stones and other diseases. 1. Prostatic hyperplasia is a common benign disease that causes urination disorders in men. Its causes are mainly related to aging and functioning testicles. The main manifestations include frequent urination, which is more obvious at night, as well as difficulty in urination, delayed urination, intermittent urination, and weak urine flow. 2. The factors of urinary stone formation are related to age, gender, heredity, dietary habits and so on. The main manifestations include renal colic due to stone obstruction, hematuria, and symptoms such as frequent and painful urination. Once such symptoms appear, after they cannot be relieved on their own, they should go to the hospital immediately for standardized diagnosis and treatment. Under the guidance of the doctor, follow the medical advice to avoid blindly, self-medication.
