Outcome Measures

Primary Outcomes (6)

  • Visual-analogue Pain Scale

    Visual-analogue pain scale is a tool used to measure pain intensity at a specific timepoint, asking a patient to use visuals to rate their pain on a scale of 1 to 10. Results are reported as units on a scale, minimum 1 (experiencing the least amount of pain possible) to maximum of 10 (experiencing an unbearably high amount of pain). Lower scores provide a better outcome for the patient as they are experiencing less pain post-operatively.

    post-operative day 3

  • Visual-analogue Pain Scale

    Visual-analogue pain scale is a tool used to measure pain intensity at a specific timepoint, asking a patient to use visuals to rate their pain on a scale of 1 to 10. Results are reported as units on a scale, minimum 1 (experiencing the least amount of pain possible) to maximum of 10 (experiencing an unbearably high amount of pain). Lower scores provide a better outcome for the patient as they are experiencing less pain post-operatively.

    post-operative day 7

  • Visual-analogue Pain Scale

    Visual-analogue pain scale is a tool used to measure pain intensity at a specific timepoint, asking a patient to use visuals to rate their pain on a scale of 1 to 10. Results are reported as units on a scale, minimum 1 (experiencing the least amount of pain possible) to maximum of 10 (experiencing an unbearably high amount of pain). Lower scores provide a better outcome for the patient as they are experiencing less pain post-operatively.

    post-operative day 14

  • Visual-analogue Anxiety Scale

    Visual-analogue anxiety scale is a tool used to measure anxiety intensity at a specific timepoint, asking a patient to use visuals to rate their current anxiety on a scale of 1 to 10. Results are reported as units on a scale, minimum 1 (experiencing the least amount of anxiety possible) to maximum of 10 (experiencing an unbearably high amount of anxiety). Lower scores provide a better outcome for the patient as they are experiencing less anxiety post-operatively.

    post-operative day 3

  • Visual-analogue Anxiety Scale

    Visual-analogue anxiety scale is a tool used to measure anxiety intensity at a specific timepoint, asking a patient to use visuals to rate their current anxiety on a scale of 1 to 10. Results are reported as units on a scale, minimum 1 (experiencing the least amount of anxiety possible) to maximum of 10 (experiencing an unbearably high amount of anxiety). Lower scores provide a better outcome for the patient as they are experiencing less anxiety post-operatively.

    post-operative day 7

  • Visual-analogue Anxiety Scale

    Visual-analogue anxiety scale is a tool used to measure anxiety intensity at a specific timepoint, asking a patient to use visuals to rate their current anxiety on a scale of 1 to 10. Results are reported as units on a scale, minimum 1 (experiencing the least amount of anxiety possible) to maximum of 10 (experiencing an unbearably high amount of anxiety). Lower scores provide a better outcome for the patient as they are experiencing less anxiety post-operatively.

Eligibility Criteria

Age18 Years+
Sexmale
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Men undergoing 3-piece penile prosthesis placement under general anesthesia at Mayo Clinic - Rochester.
  • ≥ 18 years old.

You may not qualify if:

  • History of opioid exposure within the preceding 90 days prior to surgery (based on patient-report, review of the electronic medical record, and NMP prescribing database review)
  • Current or prior history of alcohol or drug abuse (illicit or prescription)
  • History of chronic pain conditions (chronic musculoskeletal pain, fibromyalgia, central sensitization, chronic pelvic pain syndrome, etc.)
  • History of cardiac arrhythmia or untreated severe cardiovascular disease
  • Uncontrolled hypertension
  • Hepatic insufficiency
  • Renal insufficiency (CKD stage IIIa or greater)
  • Current anti-platelet or anti-coagulation therapy with plans to continue at the time of prosthesis placement
  • Poorly controlled diabetes mellitus (defined as HgbA1c \> 8.5 within 30 days of surgery)
  • Concurrent adjunctive operative procedures planned at the time of penile prosthesis placement (examples: male urethral sling, Peyronie's disease straightening with penile plication or incision/grafting)
  • Concurrent non-prosthetic surgery planned at the time of penile prosthesis placement (examples: circumcision, hernia repair, hydrocelectomy, etc.)
  • Planned infrapubic or subcoronal incision at the time of penile prosthesis placement
  • Patients who will be undergoing prosthesis placement using local, monitored, or spinal anesthesia (i.e. non-general anesthesia)
  • Allergy or history of intolerance to any local anesthetic agents included in the protocol
  • History of prior penile prosthesis or artificial urinary sphincter surgery
  • +1 more criteria
