The Correlation Between the New Rigiscan Plus Software and the Final Diagnosis in the Evaluation of Erectile Dysfunction

Abstract

The RigiScan Plus software introduced 4 new parameters that facilitate interpretation of the RigiScan data. The new software did not improve the correlation with the final diagnosis compared to the subjective single best event analysis but added new objective parameters, measured and displayed by the software, that facilitate use of the data by the physician.

New concept parameters of RigiScan in differentiation of vascular erectile dysfunction: Is it a useful test?

“…This is due to decreased androgen levels, changes in corpora cavernosa and penile vascular structure. Additionally, there are no standard evaluation criteria of NPTR and different studies have considered various criteria 10,11,28,29 . In the present study, we used NPTR criteria described by Levine and Carroll and the manufacturer of RigiScan 10,11 …”

The correlation between penile tumescence measured by the erectometer and penile rigidity by the RigiScan

“…We analysed the RigiScan data with the RigiScan plus software. [12][13][14] The erectometer was placed on the penile shaft between the two loops of the RigiScan (Fig. 2).…”

A young man with position-dependent erectile dysfunction: diagnostic work-up and interventional therapy of an arteriovenous malformation

“…We assessed the International Index of Erectile Function (IIEF)3 and found a score of 18 at baseline, 21 at 3-months' follow-up and 18 at 24-months' follow-up (no ED at IIEF score >21). To objectify the functional changes we measured penis rigidity using RigiScan Plus® at baseline and 3-months' follow-up:4 after intracavernosal application of 10 μg alprostadil and achieving maximal erection, data were acquired continuously while the patient alternated between standing and lying positions with a minimum episode duration of 5 minutes. As rigidity on the penile tip has proved to be the best overall predictor of erectile dysfunction,4 we used this parameter as our main outcome criterion.…”

As rigidity on the penile tip has proved to be the best overall predictor of erectile dysfunction,4 we used this parameter as our main outcome criterion. Values for all useable lying and standing intervals were compared by applying a paired samples t-test (Figure 2); p<0.05 was considered significant.…”
