Lichen Sclerosus Comorbidities and Complications from a National Sample of Patients Treated with Urethroplasty.

Introduction: We characterize comorbidities and inpatient complications of patients with lichen sclerosus who underwent urethroplasty from a large national patient data source.

Methods: We queried the Nationwide Inpatient Sample for patients who underwent urethroplasty between 2000 and 2010. We compared demographics, comorbidities, complications, length of hospital stay and hospital charges for patients with and without the diagnosis of lichen sclerosus.

Results: An estimated 13,700 urethroplasties were performed in the United States during the study period. Patients with lichen sclerosus comprised an estimated 3.8% of the urethroplasty population. The majority of patients with urethral stricture with lichen sclerosus were Caucasian (84%) and older, with 63% age 45 or older. Chronic hypertension, diabetes mellitus, rheumatoid arthritis/collagen vascular disease and obesity were associated with increased odds of having a lichen sclerosus diagnosis. The central East Coast (7.2%) and the Pacific Northwest (6.3%) had the highest percentage of patients treated with urethroplasty with lichen sclerosus. Patients with lichen sclerosus had longer hospital stays than those without lichen sclerosus (3.5 vs 2.6 days, p <0.0001). Patients with lichen sclerosus had more complications and hospital charges than those without lichen sclerosus but these differences did not reach statistical significance.

Conclusions: A higher percentage of patients with lichen sclerosus had comorbidities, increased complications and longer hospital stays compared to patients treated with urethroplasty without lichen sclerosus. Our findings demonstrate the increased complexity that providers face when treating men with lichen sclerosus related urethral stricture disease.
