Women who keep trying to urinate but do not urinate much each time are most likely to have an infection in the urinary tract or to have a urinary tract obstruction due to which further examination at the hospital is recommended. Possible causes are as follows: 1. Acute cystitis and urethritis, which can appear as congestion and edema of the mucosa of the bladder and urethra. At this time, the bladder sensitivity is increased, and when there is a little urine in the bladder, it can produce a strong urge to urinate, because there is not much urine, so the amount of urination is not much. Urine needs to be retained for routine urine and urine culture tests, and if the presence of an infection is confirmed, active anti-infection treatment is required. 2. The presence of urethral strictures and urethral stones can result in a low urine output during urination. When the urinary tract is obstructed and a large amount of urine is retained in the bladder, there will be an urgent urge to urinate. Due to the increased resistance of the urethra, the urine in the bladder cannot be completely expelled from the body, so there is a strong urge to urinate, but the volume of urine is not much each time. Urethroscopy is required, as well as routine urine tests to rule out infection. If urethroscopy determines the presence of stones or infection or strictures, treatment such as urethral dilation or urethroscopic stone extraction is required.
