When to urinate after removing the urinary catheter for urinary retention needs to be decided according to the condition and the amount of water consumed, within half an hour in short, usually within 2~3 hours for normal urination, and in some cases, even unable to urinate normally.
Usually, mild to moderate urinary retention can urinate within half an hour after removing the urinary catheter if you drink more water. Generally, the interval between urination is about 2~3 hours, and the interval between urination will be shortened on this basis for those who drink a lot of water.
Secondly, recurrent urinary retention caused by urinary system diseases, such as prostatic hyperplasia, neurogenic bladder, etc., can not resume normal urination for several hours or even longer after removing the urinary catheter. At this time, in addition to paying attention to drink more water, if necessary, can also use terazosin and other medications to prevent the recurrence of urinary retention.
Therefore, there are individualized differences in how long it takes to return to normal urination after removal of the urinary catheter for urinary retention, and medications should be applied appropriately under the guidance of a physician.
