Objective: The literature is inconclusive whether the Diabetes Mellitus (DM) is an infection risk factor for penile prosthesis surgery. To investigate the relationship between DM and prosthesis infection, we analyzed our patients data, especially with fasting blood sugar (FBS) level immediately before the surgery.

Materials: 481 Korean men had penile prosthesis surgery 2/2014 to 6/2017 by single surgeon and were analyzed retrospectively. All patients had at least 4 hours of fasting before the surgery and FBS was immediately before shaving the patient in preparation for the surgery. In no case was surgery canceled for reasons of FBS level. All patients have a minimum of 5 months follow up. 41.4% of our patients reported a history of diabetes.  To our knowledge this is the largest series of diabetics reported in the literature

Results: Mean patient age was 59.5±9.4. 472 patients had 3-piece inflatable penile prosthesis (Coloplast 341, AMS 131) and 9 had malleable penile prosthesis (Coloplast 8, Tube 1). First time implant cases were 447 (439 inflatable, 8 malleable) and 34 (33 inflatable, 1 malleable) had a revision surgery. There were 199 Diagnosed DM patients (41.4%). Most were type II (n=189). According to FBS level, patient group was categorized normal (<100mg/dl, 142, 29.5%), glucose intolerant (100~125mg/dl, 168, 34.9%) and DM (>125mg/dl, 171, 35.5% 126~387). DM group’s BST level varies 126~387mg/dl (mean 184.91mg/dl). There were total 6 cases of infection (1.27%). All were virgin cases (inflatable: 5, malleable: 1). Total infection rates of each group were similar; 2/142 (1.4%), glucose intolerant; 2/168 (1.2%) and DM; 2/171 (1.2%). No statistical difference (p=0.854) between the groups. Logistic regression analysis shows that neither diagnosed DM, BST level nor revision surgery is a postoperative infection predictor.

Conclusion: There was no relationship between diagnosed DM or preoperative FBS level and subsequent penile prosthesis infection in this large single surgeon series of Korean men.
