Do I need to measure my urine output when cathing?

Your healthcare professional will let you know if you should measure your urine output during your self-cathing routine. This may be something suggested to you when you first start self-cathing to help develop a routine and avoid overfilling the bladder. A fluid tracker to monitor how much you drink and your urine output may help with this. You can monitor your output using a metered collection bag or other receptacle with measurement markings.
