Objectives: To report the prevalence of low serum testosterone (LST) in men undergoing artificial urinary sphincter (AUS) placement at a single high-volume institution. Methods: We retrospectively reviewed all men undergoing AUS procedures by a single surgeon from January 2015 to January 2018 to identify men with pretreatment total serum testosterone levels. LST was defined as less than 280 ng/dL. Patients with only posttreatment testosterone levels were excluded. Demographic characteristics and clinical outcomes were compared between men with and without LST. Results: Among 113 patients who underwent AUS with pretreatment serum testosterone levels drawn an average of 2.2 months before AUS surgery, 45.1% (51 of 113) met criteria for LST, including 18 patients on androgen deprivation therapy. The rate of primary LST was 34.7% (33 of 95). The median total serum testosterone level among men with LST was 118 ng/dL (interquartile range 6-211), and 413 mg/dL (interquartile range 333-550) in the normal serum testosterone group. There were no differences in patient age, history of radiation, erectile dysfunction, or other comorbidities between the groups. Body mass index was higher in the LST group compared to normal serum testosterone (30 vs 27 kg/m2, P =.001). Cuff size and rates of transcorporal cuff placement were similar between groups. Conclusion: Nearly one-half of men with stress urinary incontinence undergoing AUS placement present with LST. While AUS cuff erosion appears to be more common in men with LST, further study is needed to determine if treating LST will reduce cuff erosion rates.
