Is Self Dilate After Meatal Urethral Dilation Surgery Required?

Hi, I had a Meatal Urethral Dilatation recently. I was advised by my consultant to have this procedure due to tightening of the meatal opening. A condition that started 2 years ago and steadily got worse. The consultant said it had an 80% success rate. He mentioned I would be taught to self dilatate after the operation. I was shown this procedure today and find this straight forward to do. However, whether its due to nerves or concentrating on the information given, I always have a good few questions I d wished I d asked at the time. I am also finding it difficult to contact my consultant. Therefore any help on the following questions would be gratefully received. 1), Exactly how long will I be expected to self dilatate? 2), Was the procedure I had done considered a success providing I self dilatate forever more or occasionally? 4), I have read on the internet a Meatatomy provides a much better chance of a complete cure. Is this true? 5), Does a Meatatomy still involve self dilatation after the operation, if so, for how long? 6), If I was to follow my consultants advice to self dilatate every day, I have read on the internet, in the long term causes secondary healing and scarring and causes a tighter stricture. Is this true? 7), Please could you provide any advice on any other treatments to provide a long term cure and exactly what they may entail? Many thanks for any answers you can provide here, it is very much appreciated. Stuart
