Twenty cadavers of men aged between 33 and 83 were examined. Cavernosometry was performed in all specimens. Afterwards in five cadavers the flow rate was increased until a herniation of the TA appeared. A strength about 1500mm. Hg was found. Similar results were found in four who had an inflatable prosthesis (AMS 700) inserted, and the intraprosthetic pressure increased until a deformity was noted. Slices of TA (thickness 1.3 to 3.3mm.) from 11 specimens were tested in a tensiometer. The elasticity coefficient was found to be around 108 N/m2, and the tensile strength to be 600 to 750mm. Hg (104 to 105 N/m2). The difference between the tensile strength achieved in the tensiometer and during saline infusion is possibly caused by the intracavernous framework. Microscopy showed that TA is mainly composed of collagen fibres which are situated in an undulating arrangement, with a few elastic fibres arranged longitudinally which connect the undulating bundles of collagen fibres. When the tissue is overstretched, the elastic fibres are destroyed and the undulating arrangement disappears. © 1990 by The American Urological Association Education and Research, Inc.FiguresReferencesRelatedDetailsCited ByDA SILVA E and SAMPAIO F (2018) Urethral Extensibility Applied to Reconstructive SurgeryJournal of Urology, VOL. 167, NO. 5, (2042-2045), Online publication date: 1-May-2002.Raviv G, Vanegas J, Petein M, Schulman C, Danguy A, Kiss R and Wespes E (2018) BIOCHEMICAL ALTERATIONS OF THE TUNICA ALBUGINEA IN IMPOTENCEJournal of Urology, VOL. 158, NO. 5, (1778-1782), Online publication date: 1-Nov-1997.Brock G, Hsu G, Nunes L, von Heyden B and Lue T (2018) The Anatomy of the Tunica Albuginea in the Normal Penis and Peyronie's DiseaseJournal of Urology, VOL. 157, NO. 1, (276-281), Online publication date: 1-Jan-1997.Wessells H, Lue T and McAninch J (2018) Penile Length in the Flaccid and Erect States: Guidelines for Penile AugmentationJournal of Urology, VOL. 156, NO. 3, (995-997), Online publication date: 1-Sep-1996.Watson D and Morgentaler A (2018) Spontaneous Corporeal Herniation of the Penis: A New Abnormality of the Tunica Albuginea?Journal of Urology, VOL. 153, NO. 3, (737-740), Online publication date: 1-Mar-1995.Hsu G, Brock G, Martínez-Piñeiro L, von Heyden B, Lue T and Tanagho E (2018) Anatomy and Strength of the Tunica Albuginea: Its Relevance to Penile Prosthesis ExtrusionJournal of Urology, VOL. 151, NO. 5, (1205-1208), Online publication date: 1-May-1994.Iacono F, Barra S, De Rosa G, Boscaino A and Lotti T (2018) Microstructural Disorders of Tunica Albuginea in Patients Affected by Peyronie's Disease with or without Erection DysfunctionJournal of Urology, VOL. 150, NO. 6, (1806-1809), Online publication date: 1-Dec-1993.Penson D, Seftel A, Krane R, Frohrib D and Goldstein I (2018) The Hemodynamic Pathophysiology of Impotence Following Blunt Trauma to the Erect PenisJournal of Urology, VOL. 148, NO. 4, (1171-1180), Online publication date: 1-Oct-1992.de Goes P, Wespes E and Schulman C (2018) Penile Extensibility: To What is it Related?Journal of Urology, VOL. 148, NO. 5 Part 1, (1432-1434), Online publication date: 1-Nov-1992.Seftel A, Oates R and Goldstein I (2018) Use of a Polytetrafluoroethylene Tube Graft as a Circumferential Neotunica During Placement of a Penile ProsthesisJournal of Urology, VOL. 148, NO. 5 Part 1, (1531-1533), Online publication date: 1-Nov-1992.Cendron M, Whitmore K, Carpiniello V, Kurzweil S, Hanno P, Snyder H and Duckett J (2018) Traumatic Rupture of the Corpus Cavernosum: Evaluation and ManagementJournal of Urology, VOL. 144, NO. 4, (987-991), Online publication date: 1-Oct-1990.
