It is not that simple as you think.
If he is suspecting a stricture then it is better to do under anesthesia, where he can correct the defect at the same time.
If he is not sure about the stricture then cystoscopy can be done as a office procedure and you can go back home the same day.But then if unfortunately a stricture is found cystoscopy has to be done later under anesthesia to correct it.
Another option is to do a RGU - a Dye test with X ray which will detect if you have a stricture or not.
Depending upon the RGU report cystoscopy can be planned.
If they correct the stricture during the cystoscopy, then the tube will be inside for 48 hours and you can on second day after the procedure.You may not want to drive after the procedure as you will be weak after the surgery.
will be painful for couple of days and then it will be normal.Painkillers will be given for the pain.
You can resume your duties once you leave hospital.You should avoid heavy work for a week or so.
I hope this answers your doubts.
