Objective:
The aim of the present study was to evaluate the therapeutic potency of an electrotherapy of striated ischiocavernous muscles in patients with erectile dysfunction.
Patients And Methods:
Transcutaneous electrostimulation of striated ischiocavernous muscles by self-adhesive penile or perineal skin electrodes was performed in 48 patients with erectile dysfunction. 6/48 patients (R) responded to intracavernous pharmacotherapy while 42/48 (NR) did not show significant penile rigidity even to intracavernous papaverine/phentolamine/PGE1 triple drug medication.
Results:
Within the observation time of 3 months, 10/48 patients dropped out. 22/38 patients reported a penile rigidity for sufficient sexual intercourse whereby 3/22 NR required additional intracavernous pharmacotherapy. Penile rigidity could be objectivated by triple drug medicaton in 12/14 NR after ischiocavernous muscle stimulation (EIS) therapy. 5/6 R were treated successfully for premature erection loss. During EIS treatment neither discomfort nor complications could be observed.
Conclusion:
Transcutaneous electrostimulation of ischiocavernous muscles is a new, noninvasive therapy for the improvement of penile rigidity. The clinical results underline the importance of the striated ischiocavernous muscles for penile rigidity.
