The New Digital Flexible Ureteroscopes: ‘Size Does Matter’ – Increased Ureteric Access Sheath Use!

Abstract

A statistically significant increase in sheath use was observed in the new-generation digital flexible ureteroscopy group. Despite the improvement in image quality, better durability and improved stone clearance, there are some potential drawbacks of these scopes. The increased distal tip diameter can result in increased use of ureteric access sheaths and this may increase morbidity and expense.
