Everyone has their favourite.
Buy one packet of a couple of brands of pads & try them out now.
That way, you won't be buying 10 packs of ones you don't like.
I like Tena.

And one small tip... don't buy any white pants. Get blue if you can.

I went with the regular Depends for the week I had a cath and wore only the diaper and a loose fitting tee shirt. I draped a pad over the chair I sat in and those two worked fine.

You will need to get some shields that slip into your underwear for after your cath come out. They have thicker and thinner ones you will likely need both.

IMO Depends are the top brand, Tena is good too. At first I was leaking a lot, so wore a depends with an extra pad in it at night. I could pull the pad out if it was wet and not need to change the depends. A mattress protecting pad is a good idea too, You might get lucky and not have much incontinence. Good luck.

Hope and pray your experience is like mine! Only used one or two “diapers”. Continence returned quickly.

I had no incontinence problems immediately after surgery. Yes, they put in a catheter. I had it for two weeks since my surgery was 16 years ago, today they leave it in for around seven days. . Never had any leaking around it, Some people do report that but all you need is a pad.

After I had the catheter removed, I did not have incontinence, About 10% of people report that.

I did start having incontinence about 10 after surger. I found the Tena Pads worked really well. Amazon sells them. After having problems with Incontinencefor 6 years, I had an AUS put in and now I don’t have any problems . I just mentioned that so you know there is no reason you have to live with it.

Don’t buy too many pads right away. You never know what your level of incontinence will be and what you need until you actually have that catheter out.

The nurse gave me 3 pampers after removing the catheter. That gave me time to see how much of a problem I'd have.
I only had/ have stress incontinence. Many choices on Amazon for underwear with built in padding.

Don’t buy large quantities at a time till you find out what works best for you. I started with depends pull ups as leaking was bad to start. But also had larger pads waiting on shelf for the next step. Ending up now 3 years latter with tenna grade is my favorite for minor leaks 2 teaspoons in 24 hours. But I have a friend that went home from hospital and never leaked at all.

Hi,
Start with the most absorbent(usually full briefs) and keep moving down to less absorbency. I used Depends full briefs at first then moved down to Depends max which I use today.

My winning combination after my catheter was removed was a Depends pull-up fitted with a Kroger (generic) brand heavy pad. I’d go through one pull-up a day and any number of pads, depending on how I was doing.

Eventually, I was able to switch to a medium-weight Tena pad worn inside my own briefs, no pull-ups required. Nowadays, as I continue to (slowly) improve, I’m at a very thin Depends shield for the first part of the day, then I finish out with the Tena pads - I’m at one shield and two pads a day now, worn from around 8AM to around 10:30PM, and as long as I avoid bladder irritants, I leak less than 100ml a day.

In brief (no pun intended), I am not sure that there is a lot of difference between the various jockey short briefs, so any brand will do: Depends, Tena, etc. But that is what I recommend. There is a progression (usually), from full jockey-style briefs/underwear diapers, to "pads" worn in briefs or boxer briefs, then finally "Shields"...the thinnest pads used several months post-surgery, to catch the little leaks and squirts that will occur. I started wearing the Shields at around 6 months or so. At 17 months post-op, I still use a Shield "just in case." I am 98-99% continent, but if I drink too much or forget to go to the bathroom every two hours whether I need to or not, I will then stand the highest chance of a leks or squirt - mostly while sitting down into my car or a chair, or squatting to pick something up. Do remember that for the first 10-14 days you will have a catheter. So...that will require wearing loose-fitting boxers, or going commando under some out shorts or pants.
I am not sure what your employment situation is - "retired" or "working", but you will be off work recovery for what is likely that entire 10-14 days. Some men here on this blog, speak of having returned to work within a few days post-surgery. I think that is ultra-rare and job dependent. If you are having the single-incision, DaVinci radical prostatectomy, you will not be able to return to any "routine"...work or otherwise, especially if your work is physical involving lifting/moving heavy objects, etc.. Your surgical wound and the trauma/pain to your body will "INSTANTLY" stop you. I personally felt "very deep" pain...like I had been pummeled and assaulted below my navel. I felt that for 3-4 weeks minimum. In the weeks after surgery, I was slowly moving around my house from one place to another to "sit", "recline", or "lay down" for the first week or two. Your doctor will tell you not to drive as well, because of the likely need to suddenly move your lower body to hit the brakes. Also, the subtle twisting of your torso and body getting into and out of a car will limit you. All of those little things that we take for granted, will become pain-limiting priorities in your post-surgical weeks.
In either case, something required me to leave my house a couple times while I still had the catheter in. You will receive two catheter bags: 1 big one for sitting around your house and sleeping, and 1 small leg-strap-on that is for short duration errands or going to work if you must. That small strap-on bag fills rather quickly, in about 2 hours "give or take". If you are feeling well enough to return to your desk job, you will be lifting your pant leg to see how full the bag is. You will of course "feel" the weight of the filling bag on your lower leg where it is strapped. You'll be going to the bathroom more often than you likely did before the surgery, to empty your catheter bag. I had an extra pair of socks in my car in case I had a leak from the small leg strap-on bag. It fortunately never happened, but that could be a messy, uncomfortable, and "wet" experience if it leaked. You would likely feel it right away though.
If you work from home, or can get your boss to "allow" you to work from home under the circumstances, you'll be better off. These days, employers can tell when you are logged into the work system and are actively working on your computer, so if they are so inclined, they can monitor your "remote presence" online to affirm that you are actually working. If you feel that you can't work, remember that the State in which you live has a State Disability program that kicks in usually after 5-7 days of consecutive days of absence. Your wages will be less, but depending on the state, you may be able to augment your income to "full income" by using some accumulated PTO/vacation time if needed. I was fortunately retired, so none of that came into play for me. Good luck to you. Let us know how everything went as an add-on message to this original message.
