Frequent urination, urinary urgency, incomplete urination, and increased nocturia are abnormal urination conditions, causing the corresponding conditions and urinary system abnormalities, and common causes include urinary tract infections, urinary stones, tumors, and prostate hyperplasia. 1. Urinary tract infection: Infection (urethritis, cystitis, etc.) can lead to thickening of the mucous membrane of the urinary system, edema, resulting in irritation of the urinary tract causing symptoms. 2. Urinary stones: urinary stones (bladder stones, etc.) will scratch the walls of the urinary system and cause repeated irritation to the stone site, resulting in urinary tract irritation and causing related symptoms. 3. Tumor: Tumorous lesions (bladder cancer, etc.) cause destruction of the surrounding mucous membrane, resulting in peripheral irritation, which can also cause related symptoms. 4. Prostatic hyperplasia: Prostatic hyperplasia causes urethral compression, which affects the urination condition and also leads to the corresponding symptoms. Psychological factors, pregnancy can also cause related symptoms, need to be combined with clinical examination to determine. If there are obvious abnormalities in urination, accompanied by hematuria and symptoms of pain and discomfort, it is necessary to consult a doctor for timely observation and standardized treatment under the guidance of the clinician.
