I have an ineffective sphincter and urethral stricture due to medical negligence. I am using an adhesive external catheter and leg bag to get out and about. At home and at night I use pads to allow the skin to rest and breath. I am due to go on holiday soon and was wondering if anyone has experience of flying while using a leg bag. Specifically what happens when the cabin air pressure drops, I am worried that the leg bag may leak or worse would it burst? Any advice would be a great help to me.
