    Ureteroscopy may adversely affect erectile function

    Worsening of erectile dysfunction score reported by 42% of study patients


    Limitations include small sample size

    “Certainly there is the potential for some selection bias in our study, and perhaps men who develop new-onset ED are more likely to complete the post-ureteroscopy SHIM questionnaire,” Dr. Shah said.

    Small sample size is another limitation of the study and would account for why the percentages of men with worsening of ED grade among those with mild and moderate ED initially did not achieve statistical significance.

    Now, the investigators hope to gather additional data from more men who undergo ureteroscopy. They would also like to collect serial follow-up data to investigate the longevity of a possible effect of ureteroscopy on ED.

    In addition, if they find uretersocopy does affect erectile function, they would like to determine the cause. Dr. Shah proposed several mechanisms, including injury to the dorsal nerves supplying the penis from mechanical trauma or the anesthesia, stent placement, or a post-surgery psychological phenomenon.
