Tight Swimming Trunks to Prevent Post Scrotal Surgery Hematoma An Experimental Justification
Abstract
Purpose: To conduct a study to measure the pressure effects of the different scrotal supports appliedon a simulated expanding scrotal hematoma.Materials and Methods: We created a model of an expanding hematoma with simultaneous pressurerecording using a urodynamics system. Pressures were recorded independently first without applicationof any support. Then, three types of scrotal supports were tested, including Euron Net Knickers,scrotal suspensory bandage, and tight swimming trunks brand Speedo® brief and shorts. Subsequentpressures were recorded using the model created, which was applied inside the supports worn by twomale volunteers A and B.Results: Without any external compression, the pressure inside the simulated expanding hematoma“balloon” reached a maximum of 15 cmH2O. The pressures measured whilst wearing “Netelastknickers” in both subjects A and B reached a maximum of 15 cmH2O suggesting that this garmentexerted no measurable compression. The suspensory scrotal support was then tested in both subjects.As the balloon started to fill with saline, the simulated hematoma pushed the scrotal support forwardresulting in falling of the balloon outside the scrotal support. Subsequently, Speedo® briefs and shortswere tested. With Speedo® briefs, maximum filling pressures of 49 cmH2O and 40 cmH2O werereached in subjects A and B, respectively. When using Speedo® shorts, however, maximum pressuresof 55 cmH2O in subject A and 54 cmH2O in subject B were reached at the end of the balloon fillingto 300 mL of saline.Conclusion: The use of tight swimming trunks (Speedo®) has led to satisfactory results in the preventionof hematoma post scrotal surgery.
