Electromyographic changes after deep dorsal vein arterialization.
OBJECTIVE
To investigate the cavernosal electromyographic changes after deep dorsal vein arterialization.


METHODS
Corpus cavernosum electromyographs (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
The mean preoperative amplitude and relaxation degree measurements were found to be 77 +/- 11 microV and 34 +/- 8%, respectively. The same recordings 1 year after the operation were 140 +/- 24 microV and 76 +/- 11%, respectively. Comparisons of preoperative and postoperative values revealed statistically significant results (p < 0.0001).


CONCLUSIONS
Smooth muscle restoration of cavernous tissue was proved by observing the postoperative increases in the amplitude and relaxation degree parameters of CC-EMG.
