Abstract

Introduction: The DrillCutTM morcellator is marketed for its fast and highly efficient removal of prostatic tissue and a higher level of patient safety. However, a paucity of publications has looked into its actual efficacy and safety. The aim of our study was to evaluate its ex vivo and in vivo efficiency and to compare its results with other devices presented in the literature. Patients and Methods: We conducted a prospective pilot study on patients who underwent holmium laser enucleation of the prostate (HoLEP) from 2017 to 2018 using the Top-Down technique. Enucleated adenomas were morcellated using the DrillCutTM morcellator. We collected both preoperative and operative data. Operative data included the enucleated adenoma weight and operative time. Various morcellator parameters were collected including morcellation time and efficiency. We recorded the encountered complications and device malfunction. Ex vivo characteristics were evaluated in terms of morcellation speed and aspiration power. Results: Sixty consecutive patients with a median age of 72.8 years were included. The enucleated adenoma was retrieved in 12.5 min (4-58). The median resected prostatic weight was 90 g (44-242). The DrillCutTM efficiency was calculated as 6.46 g/min (2.7-15). Only one patient had a simple bladder mucosal injury. Device malfunction was encountered in 4 patients (6.6%) due to blockage of the morcellator blades. The ex vivo aspiration speed was 52 s/L, while the morcellation power was 14 g/2 min. Conclusion: Our results showed that the DrillCut morcellator was effective and safe in managing our patients post-HoLEP. The DrillCutTM has better ex vivo morcellation power but modest aspiration speed in comparison to other morcellators. © 2018 S. Karger AG, Basel. All rights reserved.
