Use of transurethral alprostadil (MUSE) (prostaglandin E1) for glans tumescence in a patient with penile prosthesis

Abstract

The presence of communication between the emissary veins from the corpora cavernosa and the circumflex veins draining the corpus spongiosum makes it possible for the transfer of alprostadil (prostaglandin E1) in MUSE from the spongiosal compartment to the cavernosal compartment of the penis after its absorption through the urethral mucosa. This leads to engorgement and tumescence of the corpus spongiosum as well as the corpora cavernosa. Lack of tumescence of the glans penis and poor penile girth can be a cause for disappointment and frustration in patients following penile prosthetic surgery. MUSE was used successfully in a patient with a Dynaflex penile prosthesis to enhance the tumescence of the glans penis. It will be a useful adjunct for patients in similar circumstances.
