Smoking is not associated with wound complications in augmented urethroplasty: a NSQIP analysis.

Abstract

Objective: To investigate if predictors of wound complications differed between patients undergoing excision and primary anastomosis urethroplasty (EPA) and augmented urethroplasty.

Methods: The National Surgical Quality Improvement Program database from 2006 to 2018 was queried for male patients undergoing urethroplasty. Thirty-day wound complications were identified and categorized (superficial/deep/organ-space surgical site infections and dehiscence). Multivariable logistic regression was performed to determine risk factors associated with wound complications. Smoking history was defined as current smoker within the past year.

Results: Urethroplasty was performed in 2251 males, with 25.46% (n = 573) using a flap or graft. There was no significant difference in wound complications for patients undergoing augmented urethroplasty (n = 17, 2.97%) or EPA (n = 45, 2.68%) (p = 0.9). The augmented group had a higher BMI, longer operative time, and longer length of stay. On multivariable logistic regression, risk factors associated with wound complications for patients undergoing EPA were diabetes (OR 2.56, p = 0.03) and smoking (OR 2.32, p = 0.02). However, these factors were not associated with wound complications in patients undergoing augmented urethroplasty.

Conclusions: Smoking and diabetes were associated with increased wound complications for men undergoing EPA, but not in patients undergoing augmented urethroplasty. Patients with comorbidities associated with worse wound healing may be more likely to have a wound complication when undergoing EPA.
