Difficulty in urination is a manifestation of abnormal urination and contains more elements, such as the clinical phenomena of having a sense of resistance to urination, incomplete urination, waiting for urination, dripping urine, prolonged urination time, and shortened urination range, all of which belong to difficulty in urination. Difficulty in urination is often caused by obstructive lesions in the urinary tract, such as prostatitis, where patients may experience a sense of resistance to urination, frequent urination, urinary urgency, urinary dripping, and white dripping after urination. In patients with prostate enlargement, the prostate gland becomes larger and compresses the urethra, which clinically manifests as prolonged urination time, dripping urine, straining to urinate, and in some cases, urinary retention may occur. Patients with bladder stones occasionally have difficulty urinating. When the stone is stuck in the neck of the bladder it can cause difficulty in urination, and after changing position the stone can move and urinate normally. If you have difficulty in urination, you can go to the hospital for urological ultrasound, residual urine measurement, and urine flow rate to clarify.
