This topic is about dealing with a common issue faced by people with a urostomy, particularly at night. Sometimes, the urostomy setup can act like a vacuum, causing urine to stop flowing into the pouch, which can lead to leaks and a wet bed. Here are some helpful tips and insights to address this problem:

1. Bag and Patient Positioning
- Ensure the pouch outlet is facing downward and the tubing from the night bag runs downhill. Avoid situations where urine has to "run uphill."
- Consider changing the side of the bed you sleep on or rotating the pouch to allow gravity to assist with drainage.
- Some users have found success by sleeping on a specific side of the bed, such as the left, with the drain pointing in the same direction.
- Position the night-bag tube between your legs so you can roll over without causing kinks or elevating the tubing.

2. Prime the System Before Sleep
- Leave a small amount of urine in the pouch before attaching the night bag to help create a fluid path, similar to starting a siphon.
- After connecting the night bag, briefly lift it above head height, then place it on the floor. This can help break any air lock. Repeat if necessary.

3. Prevent Kinks and Provide Support
- Check that the connection between your body and the bag, as well as the night-bag tubing, are not twisted.
- Use a ½-inch elasticized strap with pre-cut slits and a removable button to keep the pouch and tubing securely positioned. This strap is washable and adjustable.

4. Venting a True Vacuum
- If you suspect a real vacuum is causing the issue and the bag hangs beside the bed, try poking a tiny hole in the top of the pouch (above the urine level) to allow air in. If this solves the problem, lack of venting was likely the cause.

These suggestions aim to help manage the night-time vacuum issue and ensure a more comfortable and dry night's sleep.
