I very rarely urinate in the toilet anymore, alternating between using a Foley catheter and an external catheter.
My long time external catheter, the “Uro-Sheath” is no longer made. This was the first commercial external catheter (EC). I could re-use the sturdy vinyl Uro-Sheath for at least 2 months, making it economical. The original external catheter was a latex tube taped on the end of a condom. The condom was then taped on the penis, usually with elastoplast. The Uro-Sheath came in different sizes, had a rubber strap, and was re-usable. As a smaller man I appreciated the 1 ¼” diameter size. Since I’m also short when not erect (a ‘grower’) I had to find a way to keep the penis in. While applying it I would put the end of the penis against the exit tube. At the first urination the suction of the urine draining in the tube would pull the tissue into the bulb, holding everything in by suction.
I had to try different silicone EC's. I found that for my retractile penis a Rochester Wide Band, in 29 mm, is the best. The adhesive is near the tip. I try to have half of the glans covered by the adhesive. However, my glans would still retract and when urinating there was a buildup of urine in the enc of the EC, and the adhesive would start to peel. To keep the glans out I used Coban wrap, a flexible bandaging material, wrapping it around my penis just behind the glans. Now the glans is held out. The adhesive is important in keeping the whole thing water tight. Some persons use a smaller size latex EC, allowing the material to stretch, for a tighter fit.
While the manufacturers recommend daily changes—thus selling more—I can keep it on for five days. I’ll then use a Foley catheter for a few days. The external catheter can be re-used. The adhesive is good for three-four wears, if used with the Coban wrap around the penis.
