Scarberry KA, Thomas GM, Cowper M, et al. - This study was undertaken to determine if men with diabetes mellitus whose inflatable penile prosthesis (IPP) implantation is delayed for unacceptably high hemoglobin A1c (HbA1c) will have durable improvements in their glycemic control after achieving acceptable HbA1c levels for surgery. Men without HbA1c values at ≥1-year follow-up have been eliminated. One hundred thirty-eight diabetics undergoing IPP were identified from January 2011 to March 2019. According to results, men who improve HbA1c for IPP surgery are likely to show persistent improvement. IPP implantation in diabetic men with HbA1c <9% seems to be safe.
