Original data of an experiment on the treatment of ICM injuried ED using adjustable pressure bandaging of the crus penis

The ischiocavernosus muscle (ICM) encompasses a pair of short pinnate muscles attached to the pelvic ring. The ICM begins at the ischial tuberosity and ends at the crus of penis while covering the surface of the crus. Our previous study has shown that bilateral ICM injury can lead to erectile dysfunction (ED) and affect conception in paired females. We also observed a significant correlation between ED and ICM injury after pelvic fracture, and venous leakage at the crus of penis was detected by the patient's corpora cavernography. So we speculate that venous leakage may be caused by the reduced contractility after ICM injury and ultimately lead to ED. It has not been reported in the literature whether the use of strapping the crus of penis to block venous leakage can improve ICM injury-induced ED.The aim of this study is to establish a model of ICM injuried ED, confirm the existence of penile venous leakage by corpus cavernography, and explore a new method for the treatment of ICM injuried ED by binding the crus of penis with adjustable pressure to block penile venous blood flow.

坐骨海绵体肌（ischiocavernosus muscle, ICM）为一对附着于骨盆环的短羽状肌。该肌肉起自坐骨结节，止于阴茎脚并覆盖于阴茎脚表面。本团队既往研究表明，双侧坐骨海绵体肌损伤可引发勃起功能障碍（erectile dysfunction, ED），并影响配对雌性个体的受孕能力。我们还观察到，骨盆骨折后勃起功能障碍与坐骨海绵体肌损伤存在显著相关性，且通过对患者行阴茎海绵体造影，证实其存在阴茎脚静脉漏。据此我们推测，坐骨海绵体肌损伤后收缩功能减退可能引发静脉漏，最终导致勃起功能障碍。目前尚无文献报道，采用阴茎脚捆绑阻断静脉漏的方式能否改善坐骨海绵体肌损伤所致勃起功能障碍。本研究旨在构建坐骨海绵体肌损伤型勃起功能障碍模型，通过阴茎海绵体造影证实阴茎静脉漏的存在，并探索采用可调压力绑定阴茎脚以阻断阴茎静脉血流，进而治疗坐骨海绵体肌损伤型勃起功能障碍的新方法。
