To determine if age is an independent predictor of surgical success in patients undergoing urethroplasty. Urethroplasty performed by excision and primary anastomosis depends on vascular collateralization. Successful augmented urethroplasty depends on graft neovascularization. Older patients have more comorbid conditions including peripheral vascular disease associated with reduced penile blood flow.
This is a retrospective review of urethroplasties from 11 institutions. Primary outcome was functional success at 1 year from surgery, defined as freedom from post-urethroplasty procedures. Secondary outcome was freedom from cystoscopic evidence of stricture recurrence at 3 months. Study outcomes were compared between 2 age cohorts (<60 years old and ≥60 years old). Multivariable logistic regression analysis evaluated the influence of patient factors on our primary and secondary outcomes, using age as a continuous variable.
Of 322 urethroplasties, 258 were performed in patients <60 years and 64 in patients ≥60 years. Median follow-up was 1.8 years. The following were not significantly different between groups: stricture length or location, smoking status, number of previous urethrotomies or dilations, and urethroplasty type. The following were more common in patients ≥60 years: diabetes, hypertension, hyperlipidemia, coronary artery and peripheral vascular disease, chronic obstructive pulmonary disease, and cancer. There was no difference in need for repeat procedures or anatomic recurrence between age groups or with increasing age. Stricture length was the only statistically significant clinical factor.
Urethroplasty success may be affected by comorbidities but not age. Age alone should not be used as an absolute exclusion criterion for men needing urethral reconstruction.
