@lovelife -- I used to work at a urology office. This procedure is considered out-patient and routine. If no complications develop, you are usually sent home the same day.
Your husband will have to take antibiotics a few days before the surgery as well as a few days after to help avoid an infection.
The recovery time is usually a few hours post op, then a regular room for a few more hours, where the nurse will make sure his blood pressure is normal, give him some pain meds and then send you home with instructions to take out his catheter in a few days.
One thing that really helps post op is to hydrate, I can not stress that enough. It will help your husband pass any clots and start to urinate normally.
Best wishes to your husband for a speedy recovery.
