My experience with stents

Hello! Big fan of your Tumblr
Ever since I saw this I've been thinking about getting the PA and now I think I will! Thanks for the inspiration  I'm going to look around for anyone that might make such a device. Do you know of any? 

Also I had an idea about a retrieval method which borrows from this design. I decided to make a diagram just in case I articulate it incorrectly  Yellow: Stent, Blue: Retrieval line, Grey: Locking mechanism
It would be the locking mechanism of that cage, attached to the retrieval line. This would ideally make the retrieval line inaccessible without a form of key. (Maybe the locking mechanism doesn't have to be sticking out of the tip of the penis if there was a way to grip it whilst locking/unlocking)

Do you think this would function as a locking mechanism? Do you think this would be safer than the catheter style chastity method, with it being a retrieval line? 

And apologies if this is redundant, I just haven't seen anything like this 👀

My concern with this approach would be how you intend to deal with random erections. If you fit this design for a flaccid penis and then have an erection, chances are good you'll pull the stent out of the bladder and won't be able to reseat it until your erection goes away.

Let me start off by saying I am no doctor not even close but I do think using stents can be done quite safely if you use your brain. I have been using catheters and stents since 2006. Started out with catheters, which only lasted a year and a half, wasn’t real enough so turned to stents and since 2014 went 24/7. So far I never had a UTI not while using catheters and not while using stents. I know I’ve been close to contracting UTI`s but always noticed the changes before it got out of control. This was in the beginning of my learning curve while still using catheters, once I switched to stents it happened again. I’ll be honest, I do belief it is always better to not stick anything inside your body that doesn’t belong there but speaking for myself, the other option is definitely not better. I do realize that stent use may and can cause build-up scar tissue in your bladder and urethra but I think that is a risk I have to take. So far if I take my stent out for cleaning purposes things turn to normal within a reasonable timespan as long as this is the case I do not worry too much about it. I feel over time my body learned to accept the presence of my stent, for any inconvenience which was present in de beginning faded into the background, only to reappear at rare occasions which usually means the stent has to be cleaned. So to me it is quite simple, wearing my stent goes without any pain or any other form of discomfort if that changes something is out of the ordinary and one should act.

Thanks, I've put as much info as I can on my tumblr as well as a few how-to videos.  Unfortunately I don't know of any vendors that make these things, but I haven't kept up with chastity device members in many years.  I think there are a few good makers selling on Etsy.  
 

I haven't tried what you described with a stent, but I did attempt it with a holey foley.   The challenge I found was getting the length of the blue / retrieval line the right length.  If it's too short and you get an erection , it pulls on either the PA area, or pulls the cath out of the bladder.  If it's long enough to accommodate getting hard then the catheter fell into the bladder.  With a stent though it might work since they don't move as much.

You could put an O-ring on the end of the retrieval line and then the PA part could keep the line safely tucked away from access.  That would be pretty secure.  A stent will always be safer from a UTI standpoint, but has its own risks of course.  Good luck, play safe.

Good morning!

I've been wearing 24/7, 80% of it with a stent, for about 3 years. 

My question, has anyone noticed that their penis has developed a curve? Mine used to be straight when hard, but it has developed a curve at the spot where it bends in my padding. I think it is from the erections while being pinned down in a downward position. I actually am rethinking wearing 24/7, which is sad... Maybe I'll not wear at night, since that is where most of my erections come from while being pinned down.

What has been your experiance?

Here is an interesting Case Study they did to look at the effects of incontinence inducing stents on patients who had difficulties using balloon catheters to manage urination. 

Spoiler alert: Stents and diapers are better to manage urination than balloon catheters.  

For those who don't want to read the whole report, here's the abstract:

Report on Experiments and Clinical Cases―
 

MemokathTM Urethral Stents Induce Incontinence in Patients

with Urethral Balloon Catheters

Ryo Takahashi, Ryoji Kimata, Tsutomu Hamasaki, Yuriko Kawarasaki and Yukihiro Kondo

Department of Urology, Nippon Medical School

Abstract

Objective: With an aging society, elderly patients increasingly require long-term placement of urethral balloon catheters. In this study, we investigated if MemokathTM urethral stents, when inserted from the bladder neck to distal to the urethral sphincter in elderly men being treated with urethral balloon catheters, induce incontinence, which would then be managed with adult briefs.

Patients and Methods: Of all outpatients who were being managed with urethral balloon catheters at our institution from September 2011 through March 2012, 4 patients who had had problems with the catheters were included in the study. Exclusion criteria were a performance status of 1 or 2 and the ability to urinate after standard placement of the stent. After application of local anesthesia to the urethra, the MemokathTM stent was placed distal to the urethral sphincter under radiographic guidance in all patients.

Results: After stent placement, all patients had total incontinence and were catheter-free. Although 2 patients were receiving anticoagulant therapy before the procedure, no intraprocedural or postprocedural anticoagulant-related complications were noted.

Conclusions: MemokathTM stent-induced incontinence is a safe and effective treatment for patients requiring long-term placement of urethral balloon catheters who are expected to have continuing urination difficulties.

Anyway, when are they finally going to study the effects of these stents on the (mental) health of people who have long suffered from incurable toilet phobia (aka incontinent desires)? Solely in the interest of science and humanity, I would feel called to make myself available as a test subject.....

This is interesting.  I found a NHS (UK) study years ago that talked about using a spanner stent (I think) in the elderly in comparison with either external condom catheters or absorbent products vs intermittent or foley catheters.  In the end the outcomes were negligible in differences, but it's good to see healthcare looking down these avenues as the trickle down research helps us kinky folks.   

I'll try searching for the paper.

Hello, i read this page on and off now for years and i'am finally brave enough to try to build my own stent.

Unfortunately this thread became corrupted and also impossible to overlook every post...

So, is there a instruction set, step by step to build your own stent?

If no, what materials are you using?

I would start with a silicone catheter but i have no clue what material to put inside the tubing to do the bends, and also how to securely fix the fishing line to the tubing.

Would be great if some one could be provide with some details.

[Little Sam]

I'm sure people who actually know what they're talking about will chime in soon enough, but...

I would assume you bend a suitable gauge piece of steel to the right shape, then slide the catheter over it, and gently heat it with a heat gun or hair dryer, until it softens and takes the shape.

And umm stitch it? Then tie it off several times. Maybe even run two lines, with a little extra slack on the second, if you're paranoid and want redundancy.

Just make sure to sterilise the fuck out of everything.

The last 25+ pages load fine on my end and contain lots of how-to instructions.  I've also posted quite a bit of info and a few videos on my tumblr, https://ind247.tumblr.com/archive .  Good luck, and play safe.

Iam following your blog for a few years now, in the more recent posts you showed your stent with metal tubings, where did you got them from and dou you remove them before you slide the stent in?

Thanks for following all these years.  Years ago I switched from making stents with plastic tubing to using 5mm titanium tubing.  This way I can reuse the parts, and lower the risk of infection as plastic is a good breeding ground for bacteria.  There are several videos and post on my tumblr on how I shape and make the tubing for stent use. None of the tools are exotic or expensive, just pipe benders, cutters and files.

The tubing stays in place in the stent when I insert it, just like plastics parts.  Otherwise it would just be a silicone tube that would not stay in place.   

As I mentioned above, I've posted plenty of how-to articles and videos on tumblr on how to make the metal parts.  I just took a quick look and you could start around : (3) Diapers / Caths / Stents on Tumblr here and the few days before and after this post have lots of info.

I looked at some of your photos and videos on your Tumbler account. Well done! I also saw your call for tips and ideas for a manual for making your own stents. I'm not a member of Tumbler, so I have limited access and can't leave tips there. That's why I'm just doing it here:

Are you still using two separate titanium pieces for the bends in the stent? A few years ago I started using a one-piece inner tube and found that this helps tremendously in preventing the stent from migrating in any direction.

Maybe two disadvantages from your perspective. First, the sizing must be perfect, otherwise the stiffness will cause friction and irritation. Secondly, the inner tube must be made of plastic, because with a titanium tube the stent becomes too stiff to place it comfortably in the urethra.

By the way, I have never had a urinary tract infection when using my stents with plastic tubes. But maybe I just got lucky.

What type of plastic do you use, can you recommend my a store to buy them online?

I use those plastic straws from spray bottles that you can buy in the store. I recommend cleaning them thoroughly before using because those spray bottles often contain all kinds of chemical detergents that may harm your body. But they sell generic all purpose spray bottles on line too.

It is important that they have an outer diameter that matches the inner diameter of the silicone tubing you use for the stent.

Tomorrow I will make an instruction with pics of my work in progress and post it in a different topic. Other stent makers can put their instructions there as well.

The material for the inside tubing is simply Teflon (PTFE). It's chemically inert, highly resistant to corrosion, and easily moldable with a heat gun.

You will have to experiment with different wall thicknesses on the PTFE to find what is both strong enough but not too narrow of an inside diameter as to not constrict the flow. The outside diameter of the PTFE should match the inside diameter of the silicone for a snug fit. I recommend platinum cured silicone for the purest quality.

I believe I am using 1/8" ID x 3/16" OD PTFE and 3/16" ID x 5/16" OD platinum cured silicone.

The specific type of PTFE I'm using is FEP, or Fluoroethylenepropylene, which is the melt-processable version of PTFE. FEP has very similar properties to PTFE, but has a lower maximum operating temperature of +200°C. However, FEP can be more easily processed and can be easily welded and re-moulded into complex profiles.

Cancel that. I decided to upload my pics and instructions in a separate album on my profile. My files were too big to post them as attachments.

Excellent write-up! So if I understand right, you have a solid piece of spray bottle tubing that you snake the silicone over?

Thanks Hanna. It took me a whole day, but I enjoyed doing it. It gives me fond memories of the entire process that resulted in this perfect solution for my lifelong incontinence desires. I'm also somewhat proud that I finally gave the medical industry the middle finger by using simple, dirt-cheap materials, no lubricants or other chemicals, just my own pee, saliva and warm tap water. The only UTIs I've ever had were when I used medical grade catheters and lubricants. You almost wonder why, right?

But to answer your question: Yes, the plastic tubing is fairly solid to ensure that the stent keeps its shape and holds its position once in place. But not too solid as that would make insertion more difficult and even painful. So somewhere in the middle I guess.

You're welcome!

Next up will be a video of me inserting my stent to proof how quick and easy it goes, how effective it is and what happens if I wear jeans without a diaper. Of course I am not allowed to upload it here, but I have a Fetlife account where I will put it for every paying member to see. If there are any other non porn related platforms where I can safely upload it, let me know.

I am also aware there are quite a few people who simply don't believe I am actually using stents and that they make me incontinent for real. So by showing my video I hope to take away their doubts as well.

I have a FetLife account but do not pay for a membership. There are many sites online that you can upload the movie clip to and share, one of them being in a folder in Google Drive or OneDrive. You could just share the link to be read-only and voila, but maybe do it from an account or email that you don't mind being associated with your DD account.

[cathdiap]

@Hannah YMSThanks for the suggestions!. Let me think about it.
