So, I finished my RT in March but didn't have the catheter out till May, after which I was given self-administered ones.
Pretty soon I was peeing normally during the day, but still having trouble at night, with a pathetic trickle and bladder not emptying. The moment I got up in the morning, it was fine again! Things gradually improved and by the end of July this was more or less sorted, and I was down to about one catheter per week.
Then something happened, don't know what (I did wonder if it was related to taking Terbinafine for fungal toenails, but I'm told this isn't likely); the nighttime problems are back and now I'm back to three catheters per night. It's a real drag.
I'm seeing urology in six weeks or so, and suppose I can live with this until then if I have to, but would love to know if anyone else has had a similar experience, and what you might have done about it.
