In 34 of the 39 normal patients potentials of a uniform shape were recorded during flaccidity. At cutoff frequencies of 0.5 to 500Hz. the duration was 8 to 18 seconds (mean 12.8 ± 2.8, seconds, standard deviation), the amplitude was 250 to 750 μv. (mean 444 ± 109 μv.) and the polyphasity was 8 to 22 (mean 13.8 ± 3.3). With increasing tumescence and rigidity during audiovisual sexual stimulation, high frequency potentials of low amplitude and short duration were found in the normal patients. In impotent patients with an upper motor neuron or peripheral lesion specific types of potentials were observed. In 11 of 14 impotent patients with insulin-dependent diabetes for more than 20 years and with clinical findings of cavernous myopathy the potentials showed low amplitude, irregular shape and slow depolarizations. Abnormal findings of cavernous electrical activity were recorded in 51.6% of the consecutive impotent patients. Our clinical study suggests that single potential analysis of cavernous electrical activity may be useful in the diagnosis of cavernous autonomic neuropathy and cavernous smooth muscle myopathy. © 1991 by The American Urological Association Education and Research, Inc.FiguresReferencesRelatedDetailsCited ByJIANG X, MEULEMAN E, WIJKSTRA H and WAGNER G (2018) CORPUS CAVERNOSUM ELECTROMYOGRAPHY DURING MORNING NAPS IN HEALTHY VOLUNTEERS: FURTHER EVIDENCE THAT CORPUS CAVERNOSUM POTENTIALS REFLECT SYMPATHETICALLY MEDIATED ACTIVITYJournal of Urology, VOL. 174, NO. 5, (1917-1920), Online publication date: 1-Nov-2005.YILMAZ U, SOYLU A, OZCAN C and CALISKAN O (2018) CLITORAL ELECTROMYOGRAPHYJournal of Urology, VOL. 167, NO. 2 Part 1, (616-620), Online publication date: 1-Feb-2002.YILMAZ U, SOYLU A, ÖZCAN C, KUTLU R and GÜNEŞ A (2018) EVOKED CAVERNOUS ACTIVITYJournal of Urology, VOL. 167, NO. 1, (188-191), Online publication date: 1-Jan-2002.Fabra M, Frieling A, Porst H and Schneider E (2018) Single Potential Analysis of Corpus Cavernosum Electromyography for the Assessment of Erectile Dysfunction: Provocation, Reproducibility and Age Dependence-Findings in 36 Healthy Volunteers and 324 PatientsJournal of Urology, VOL. 158, NO. 2, (444-450), Online publication date: 1-Aug-1997.Scheepe J, Junemann K, Buhrle C, Schmidt P, Wipfler G, Berle B and Alken P (2018) Recording the Corpus Cavernosum Electromyogram: Principles and ProblemsJournal of Urology, VOL. 155, NO. 6, (2074-2079), Online publication date: 1-Jun-1996.Sattar A, Merckx L and Wespes E (2018) Penile Electromyography and Its Smooth Muscle Content: Interpretation of 25 Impotent PatientsJournal of Urology, VOL. 155, NO. 3, (909-912), Online publication date: 1-Mar-1996.Ertekin C, Colakoglu Z and Altay B (2018) Hand and Genital Sympathetic Skin Potentials in Flaccid and Erectile Penile States in Normal Potent Men and Patients With Premature EjaculationJournal of Urology, VOL. 153, NO. 1, (76-79), Online publication date: 1-Jan-1995.Lerner S, Melman A and Christ G (2018) A Review of Erectile Dysfunction: New Insights and More QuestionsJournal of Urology, VOL. 149, NO. 5 Part 2, (1246-1255), Online publication date: 1-May-1993.De Carvalho A, Roy C, Moreno A, Melman A, Hertzberg E, Christ G and Spray D (2018) Gap Junctions Formed of Connexin43 Are Found Between Smooth Muscle Cells of Human Corpus CavernosumJournal of Urology, VOL. 149, NO. 6, (1568-1575), Online publication date: 1-Jun-1993.
