A urine volume of about 100mL at one time is a condition of low urine output. The normal bladder capacity is about 300mL, but when the patient feels the urge to urinate in the bladder, the urine volume is about 120-150mL. However, at this time the patient may not have to go to urinate, the bladder can still properly store a certain amount of urine. When more than 200mL, the patient can have a more obvious desire to urinate, at this time can go to urinate. When the bladder stores up to 300mL, then there will be a strong desire to urinate, so if you do not go to urinate at this time, there is a possibility of urge incontinence. When the volume of urine is about 100mL at a time, it is a condition of slightly low urine output, but it is not a disease condition at this time. When the bladder is about 100mL per urination, it is recommended to go to the hospital for further examination to find out if the bladder capacity is too small or if there is a bladder contracture. If you occasionally urinate around 100mL at a time, there is no need to be overly concerned and regular observation is all that is needed.
