EXPERIMENT
Warnings: This is my experiment - do not attempt this at home. Use of silicone catheter would likely result in an embarrassing trip to the ER. I planned my story ahead of time - this could be extremely hard to explain and then realized there is no real way to explain this away, just tell the truth.
Objective: To eliminate catheter tubing in diaper.
Method: Using modified catheter (not for this experiment) cut just beyond urethra opening with retracted penis using thread to recover catheter and drain catheter balloon.
Materials:
Latex catheter
Hemostat – locking clamp
Jewelers pliers
Upholstery thread
Upholstery needle
Plug for catheter balloon fill tube (small tube) this was fabricated.
Procedure:
Materials other than the catheter were cleaned using alcohol. This does not create a sterile environment, but the area where they will be used is not usually considered sterile and should be flushed with urine being expelled from the bladder.
Insert Foley catheter following normal sterile procedure. For this experiment a non-modified catheter was used. With catheter in place retract penis exposing as much of the catheter tube as you can. Clamp hemostat as near to urethral opening as possible. Test to ensure that catheter balloon is not leaking. The catheter was then cut approximately 3\4 inch from hemostat away from the penis end.
A fabricated plug was then inserted into the balloon fill line that had a loop for attachment to upholstery thread (this is extremely strong thread you will not be able to break it by hand). This is how the balloon can be deflated so care needs to taken that the plug can be easily removed (I used a bit of silicone lube). The diameter of the plug is about 5 to 8 times that of the balloon tube to ensure the balloon does not deflate unintentionally.
Next using an upholstery needle & thread pierce the latex catheter near the hemostat using the jeweler pliers (smooth grip area) being sure to miss the balloon inflation tube leaving 1\2 inch of tube. This could be done twice to ensure a redundancy. Secure the ends of the threads about 6 inches from the catheter with a button. This ensures the catheter can be recovered if it migrates into the bladder. Check all work. Release the hemostat and allow the catheter to migrate into the urethra leaving only the thread exposed. The catheter tube end was now completely inside the penis.
Catheter removal was accomplished in this experiment by retracting the penis to the balloon plug, which was removed by hand without the aid of the thread. Upon deflation, the catheter was removed by pulling the thread very gently with no trauma to the urethra even though the edges were squared off.
This experiment was very successful, but not without concerns. Failure of the threads seemed unlikely as they were tested on used catheters, but uncertainties remained. This was an experiment and I’m not sure if I will continue in this effort, but the results are very satisfying.
