196 Device Autoinflation Following Penile Implant Surgery
The Journal of Sexual Medicine(2017)
Abstract
Penile implant autoinflation (AI) is a nuisance for patients, may lead to reduced patient satisfaction with their implant and reoperation when bother is high. The literature cites a rate of 11% with a 2% reoperation rate. This analysis was conducted to examine this issue in our patient population. Furthermore, we attempted to assess patient bother and to look for factors that were predictive of AI. We recorded implant (operative and complication) data on patients undergoing penile implant surgery over a 12-year period. Only patients with ≥6 month postoperative follow-up were included. AI was defined as any tumescence of the penis ≥4/10 hardness scale and analysis was conducted to evaluate patients with sub-penetration hardness (4-6/10) and those with definitely penetration rigidity level AI (>6/10). We further compared a number of other variables: lock out valve (LOV) vs non lock-out valve (NLOV) devices; location of reservoir, space of Retzius (SOR) vs any ectopic location; partial vs complete filling of reservior. Bother was assessed on a mild, moderate, severe scale. Multivariable analysis was used to search for predictors including, reservoir location, degree of filling of the reservoir, presence of LOV, radical prostatectomy, presence of Peyronie’s disease.
