I second what Cynthia said about pain. I have had TURBs twice, did not have much pain afterward, and never took any strong painkillers. Granted, my tumors were tiny, so the area "excavated" wasn't big. I used to have a lot of problems with bladder and urethra spasms, however, not just after the TURB procedure but even after cystoscopies. As well as some kind of painkiller, you may have an antispasm medication prescribed, which I heartily recommend. I used to take it before my cystoscopies, and it really helped. Over the years I guess I've gotten "toughened up" by having so many cystoscopies so I no longer have any discomfort during or after.
One thing I don't think has been mentioned is that some people have a catheter in after the TURB; sometimes people need to leave the hospital with it still in and then have it taken out in the dr.'s office later. I didn't need one either time I had a TURB. I had one TURB as an outpatient procedure in the hospital under light general anesthesia, and the second one under local in the doctor's office. I gather having it done in the office is not common, judging from the responses I got from people here!
Best of luck.
