Possible causes of frequent urination, urinary urgency and urinary waiting: 1. Urinary tract infection. When urinary tract infection occurs, symptoms such as frequent urination and urinary urgency occur due to bacterial infection leading to congestion and edema of the urethral mucosa. The symptoms of waiting for urination can occur because the patient urinates too frequently, the bladder sensitivity increases, and the urine storage in the bladder is too small. It is recommended to take urine for routine urinalysis, if the urinalysis confirms elevated white blood cell count, elevated bacterial count or elevated leukocyte esterase, then the infection can be confirmed and anti-infection treatment is needed to relieve the symptoms. 2, male prostatic hyperplasia, often seen in male patients over the age of 45 years, is caused by the prostate hyperplasia partly protruding into the bladder cavity, which causes bladder irritation and symptoms of urinary frequency and urgency. The prostatic hyperplasia causes elevated resistance in the urethra, when the bladder pressure has to overcome the urethral resistance, and the symptoms of waiting to urinate, and poor urination and difficulty in urination. It is recommended that a urinary ultrasound be performed, and if the presence of prostatic hyperplasia is confirmed, medication or surgery will be required.
