OBJECTIVES: The current study aims to investigate the value of penile elastography in assessing the fibrotic changes in the corpora cavernosa.
PATIENTS AND METHODS: Eighty participants were included in the study. These were divided into two equal groups: a study group (group 1) included patients with ED who did not respond to intracavernosal injection (ICI), and an age-matched control group (group 2) included age-matched subjects with normal erection. All subjects answered an International Index of Erectile Function-5 (IIEF-5) questionnaire. The first group was evaluated by two ICI trials of 1 mL Quadmix, each took place 1 week apart, followed by a color duplex/Doppler ultrasonography (CDDU) scan using also a 1 mL Quadmix. All the above was done a week before the penile shear wave elastography (SWE) scan. It comprised a 12-section scan of both corpora cavernosa. Each corpus was scanned in three different segments (proximal, mid-shaft, and distal), and in both longitudinal and transverse axes.
RESULTS: Comparisons of the laboratory data were non-significant, apart from the glycosylated hemoglobin which proved significant (P value <.001) in both groups. Also, the IIEF-5 scores were significantly lower in the study group (P value <.001). Significantly higher SWE readings (indicating higher fibrotic) were found in the study group compared with the control group in almost all of the scanned segments and their combinations (P value <.05).
CONCLUSION: SWE can effectively assess the fibrotic changes occurring in the corpora cavernosa. Hence, SWE could be utilized as a modality that helps diagnose patients with ED.
