You will need to ask your plastic surgeon this question. But for any procedure that exceeds 3.5 hrs, I generally will have a foley catheter placed in the patient to avoid any problems with urinary retention. The catheter is removed before the patient is awake.
For Plastic Surgery Procedures That Go on for 5 or 6 Hours Are You Catherized? Thanks! Kathy

Placing a urinary catheter
There are no clear set rules about placing a urinary catheter. In cases that last more than 4 hours it can be beneficial.
Urinary Catheter Placement
The simple answer is yes. I place a catheter if my procedures go longer than 2 hours or if I need to critically watch the urine production such as in large volume liposuction.

Urinary Catheter For Aesthetic Procedures
I place a urinary catheter for all breast reductions, tummy tucks, and abdominal liposuctions and any other procedures lasting more than a couple of hours. Unless there is a reason not to, I routinely remove the catheters before patients leave the OR.
I place a catheter for cases longer than 3-4 hours. Otherwise, patient will have discomfort (even under anesthesia) and probably wet themselves.
Urinary catheter is appropriate for operations over 3-4 hours.
The longer the surgical procedure, the longer an intravenous line runs, and the more fluid you receive. A full bladder can cause significant blood pressure changes and other physiologic responses, even in a fully asleep (anesthetized) patient. So a catheter is not only useful, but important for patient safety as well as comfort.
And who wants to have to get up and pee right after waking up from surgery?
Don't fear a catheter; it goes in after you are asleep, and I have my staff remove it before my patients wake up. But it's there when we need it! Best wishes! Dr. Tholen
Urinary catheter in longer cases
We catheterize any case over 3 hours. You will definitely need a catheter for 5-6 hr case.

Catheter placement is reasonable for bladder decompression and for monitoring of urine output in longer cases. Kenneth Hughes, MD Los Angeles, CA
When Do You Need a Catheter During Surgery?
This is a good question. In general, it is best to place catheters in patients to decompress their bladders during surgeries that are expected to last greater than 4 hours. That is a good rule of thumb to go by. I will wait until the patient is asleep before placing the catheters and will usually remove them before the patient wakes up. On longer cases, 6-8 hours, I will leave the catheter until the next morning to watch fluid output and help the patient not have to get up too much during the first night.
Some surgeries, like laparoscopy or urological procedures, may require a catheter for even shorter cases. Ask your surgeon if you will need one during your surgery. There is really almost no risk with the short use of a catheter.
