(293) Utilization of the Satisfaction Survey for Inflatable Penile Implant (SSIPI) for Assessing Patient Experience and Enhancing Clinical Understanding of IPP Therapy

Abstract Introduction Inflatable penile prosthesis (IPP) is a validated treatment for medication-refractory erectile dysfunction (ED). Objective This study uses the Satisfaction Survey for Inflatable Penile Implant (SSIPI) to assess whether IPP implantation alters penile size and whether these changes correlate with satisfaction scores. Methods We evaluated 51 patients who underwent IPP implantation at our clinic. All completed the SSIPI questionnaire at follow-up, ranging from 3 to 78 months postoperatively (mean 8.1 ± 13.7 months). Assessed variables included age, BMI, smoking status, diabetes, implant type, presence and treatment of Peyronie’s disease (PD), and pre-/postoperative penile dimensions. Pearson’s correlation was used to identify predictors of overall and domain-specific SSIPI scores, including whether changes in length or girth influenced satisfaction. Results Mean patient age was 63.1 ± 13.3 years. Virgin implantation was performed in 96.1% (49/51), and 3.9% (2/51) were revisions for mechanical failure. Coloplast Titan implants were used in 94.1%. PD was present in 29.4% (15/51); treatments included modeling (46.7%), plaque incision (20%), and excision with grafting (33.3%). Mean preoperative penile length increased from 11.5 ± 1.7 cm to 12.5 ± 2.1 cm, and circumference from 10.5 ± 1.6 cm to 13.0 ± 1.7 cm. Average change: +0.62 ± 1.66 cm in length, +2.51 ± 1.67 cm in girth. Mean total SSIPI score was 72.2 ± 8.6. Domain-specific means: overall satisfaction 18.6/20, pain 9.5/10, appearance 25.7/30, and function 18.6/20. Question 8 (Q8) assessed satisfaction with length (mean 4.25 ± 1.1, only 6 patients (11.8%) rated it below 3. Q9 assessed girth satisfaction (mean 4.57 ± 0.9); only 4 patients (7.8%) rated it below 3. No significant correlation was found between SSIPI scores and age, BMI, smoking status, diabetes, PD, or measured changes in length or girth. A weak positive correlation (r = 0.35, p = 0.012) was found between Q8 and preoperative length. Patients undergoing revision did not show lower SSIPI scores. Postoperative length gains varied widely; however, even patients with minimal or no measurable change reported satisfaction scores like those with increases, reinforcing that perceived size changes are not the primary driver of satisfaction. Device functionality and low complication rates were more influential. Conclusions SSIPI is a valuable tool for assessing patient-reported outcomes after IPP. In our cohort, high satisfaction was not dependent on objective size changes or patient demographics but was more closely linked to perceived function, comfort, and aesthetic results. These findings support effective patient counseling and address preoperative concerns about penile size post-implantation Disclosure No
