Hi, my dad has an enlarged prostate (160g!) and is due biopsy on weds (suspected cancer, not bph). He needs a catheter, but recently there's been a lot of blood and clots which block the catheter and he has to go into a&e which is very traumatic. Is there a better a solution than just waiting for the catheter to block and going to a&e. Any treatment unlikely to start for 3 weeks, and can't face 3 weeks of regular a&e visits with 12 hour waits whilst his bladder is full to burst. Help?
