You need to get your grandfather evaluated to find what is the cause of urinary retention and if prostate is the cause whether he is fit for surgery or not.
The troubles he is experiencing at this point of time are secondary to bladder spasms and you should start him on anti cholinergic medications under the care of urologist.
Patient replied :

You can start him on T. Solifenacin 5mg once daily and he should start feeling better after 2-3 days.
