Hi, I have just got a convene catheter as my husband was waking up nearly every hour to go to the toilet and I would bring a urine bottle round to him. The catheter fits well but I am having mixed success at the moment. When he wees it seems to balloon up in the space near the penis and if not released will back up and start leaking out, ruining the adhesive seal. Sometimes when I wiggle the bag it will suddenly rush through (it is on a night stand). This morning it was nearly going to start leaking again but I pulled the sides of the bag apart a it and it all started draining properly again! Obviously I don't want to be doing that all the time as it's even more disruptive than before. Does anyone have any tips? There's no kinks in the tube so I can't understand it ?
