OBJECTIVE: To investigate the effect and safety of low-intensity pulsed ultrasound (LIPUS) versus low-energy shock wave (LESW) in the treatment of neurogenic penile ED in male SD rats.
METHODS: Twenty-four 12-week-old male SD rats were randomly divided into four groups of an equal number: sham operation, bilateral cavernous nerves injury (BCNI), LIPUS (300 mW /cm2, 3 times a week for 2 weeks), and LESW (300 strokes once, 3 times a week for 2 weeks). At 28 days after intervention, the erectile function of the rats was assessed by comparing the ratio of maximum intracavernous pressure to mean arterial pressure (ICPmax/MAP), and the histopathological changes in the corpus cavernosum of the penis were observed by immunohistochemistry, immunofluorescence staining, and Masson trichromatic staining.
RESULTS: After treatment, the LIPUS and LESW groups, compared with the BCNI group, showed significantly increased ICPmax/MAP ratio (0.56 ± 0.13 and 0.55 ± 0.10 versus 0.35 ± 0.14, P = 0.017 and P = 0.013), improved smooth muscle/collagen value (0.08 ± 0.01 and 0.08 ± 0.02 versus 0.06 ± 0.02, P = 0.017 and P = 0.019), and elevated proportion of smooth muscle to cavernosum (0.20 ± 0.05 and 0.21 ± 0.03 versus 0.15 ± 0.02, P = 0.046 and P = 0.020), with no statistically significant difference between the LIPUS and LESW groups. No obvious adverse reactions were observed in the LIPUS or LESW group.
CONCLUSIONS: Both LIPUS and LESW can effectively improve penile erectile function and repair histopathological injury in the animal model of neurogenic ED.
