Abstract
Purpose: To investigate the cavernosal electromyographic changes after deep dorsal vein arterialization. Patients and Methods: Corpus cavernosum electromyographies (CC-EMG) were done in 18 patients with patent anastomosis 1 year after the operation by using coaxial needle electrodes during the flaccid state and following intracavernous 60 mg papaverine injection. Results: Themean preoperative amplitude and relaxation degree measurements were found to be 77 ± 11 µV and 34 ± 8%, respectively. The same recordings 1 year after the operation were 140 ± 24 µV and 76 ± 11%, respectively. Comparisons of preoperative and postoperative values revealed statistically significant results (p < 0.0001). Conclusion: Smooth muscle restoration of cavernous tissue was proved by observing the postoperative increases in the amplitude and relaxation degree parameters of CC-EMG.
