Abstract:
While waiting for prostate-size-reducing drugs or herbs to have an effect, it's often necessary to have a catheter, like the Foley, inserted into the bladder. Urine passing through such collects in a plastic bag which must be drained, regularly, and is awkward to carry and difficult to disguise under clothing. In lieu of a Foley, full-length self-cathetering is less awkward, but the recurring process can irritate the urethra and prostate, and increase the chance of getting cystitis. The present new catheter type has a barb-like tip to retain such inside the bladder. A urine drainage inlet is located less than an inch below the barb. The easy drainage of urine is facilitated simply by pushing the catheter upward until the inlet opening is inside the bladder. Because the required insertion distance is much reduced, there's less likelihood of there being irritation of the organs, and less likelihood of getting cystitis.
