Laser prostate ablation and enucleation: Analysis of a national cohort.

Abstract

To compare characteristics and outcomes of benign prostatic hyperplasia patients undergoing prostate laser ablation with those undergoing laser enucleation using a nationwide cohort. Men who underwent prostate laser ablation (n=10054) or laser enucleation (n=1705) between 2011 and 2015 were identified by the common procedural terminology code as recorded in the National Surgical Quality Improvement Program database. Preoperative, intraoperative and postoperative parameters were compared between the groups using univariate and multivariate analysis. Prostate laser ablation patients were older, had more comorbidities and were more likely to have abnormal laboratory values. Enucleations were significantly longer and more likely to result in a hospital stay >1day. Enucleation patients were also more likely to require a blood transfusion postoperatively, but less likely to experience urinary tract infection and sepsis on both univariate and multivariate analysis adjusted for preoperative and intraoperative factors. Although laser enucleation and prostate laser ablation are both considered minimally invasive techniques, significant differences in patient selection, intraoperative factors and postoperative complications are identified in this national cohort. The present study shows that despite similar outcomes in prospective single-center studies, prostate laser ablation and laser enucleation have distinct practice patterns in a broader national context.
