For sufferers of MS, this is no laughing matter! The Urology Dept advised me of my upcoming renal ultrasound saying: Drink a litre of water 90 minutes before your appointment until your bladder is very full and DO NOT empty your bladder prior to the procedure. Ha ha ha – you’ve got to be joking 🙄 (makes me wonder if they are fully across the problem 😂)

I was told to do the same, then got berated for going to the bathroom while I waited for an hour to see the nurse. Next time I’ll just wet my pants in the waiting room
