Learning curve in aquablation: an international multicenter study.

Objectives: To describe and analyze the learning curve (LC) of aquablation for the treatment of benign prostatic obstruction and determine the number of cases needed to achieve acceptable surgical safety, efficiency, and efficacy.

Methods: A retrospective analysis of prospectively maintained aquablation databases from France, Lebanon, and Spain was conducted. The combined LC of three surgeons was defined by trifecta and pentafecta outcomes.
