Nocturnal penile erections: A retrospective study of the role of RigiScan in predicting the response to sildenafil in erectile dysfunction patients

[madman]

Conclusions

From these findings, it can be concluded that sildenafil response in ED patients can be predicted by NPTR monitoring, using the RigiScan device, and ED patients with a RigiScan base or tip rigidity less than 42% cannot be expected to respond well to sildenafil.
