Yesterday my husband aged 85 - and normally healthy - had a bladder biopsy. It went well, and there was nothing untoward to report. However in the night, he was suffering much pain and water retention. When he was finally able to pass water it had blood in it, which apparently is quite normal after his particular procedure. Today has not been too bad, but now he seems to have gone to the other extreme, still having pain but seemingly temporarily (he and I hope ) incontinent. he is very distressed by this. Is it normal, and what can we do overnight to ameliorate the situation?
