Small bladder capacity

[Horses3]

Hi does anyone know if you can make a small bladder capacity bigger, if so how? 110mls capacity only found out couple of months ago, 12 yr old boy, wetting at night badly. We have tried oxybutin 10mg at night now, tried 5mg morning and evening originally, desmotabs 240mg at night, stops drinking at 6, nothing only water to drink, charts intake and output, drinks 2.2 litres per day, double voiding, lifting at night, alarm which he doesn't hear, still wets up to 3 times per night, pullups in past, still wets badly, doing all above since he was 7. May do botox into bladder next...any advice? Please

As far as I have had it explained, its the meds which enable it to be more stretchy, in combo with water which helps 'expand the balloon' until it can progressively hold more. You are doing all the right things. Both husband and son have bladder issues. Husband is due to discuss Botox at next appt with consultant. It must have a good chance of success for them to use it. Our son is 10, and have had this forever (day and night) so I do feel for you and your family. Its hard isn't it? Urology nurse said a proportion of boys grow out of it in teen years, something to do with prostate growing.

Have you had laxido - in case of impact from bowel pressing on bladder? x

Thanks for that, its so confusing as we were told on diagnosis that the bladder was genetically 4 times too small so couldnt be expanded, but told to keep doing all the things to expand it.....yes all clear on constipation...

Hmm that is confusing. Need to go back and ask for clarity.
