The Manufacturer and User Facility Device Experience database contains anonymous, voluntary medical device reports. A review of device-related adverse events associated with Benign Prostatic Hyperplasia surgeries was completed. The objective was to evaluate the occurrence and contributing factors to clinically significant complications in a cohort of patients electing to undergo surgical intervention for Benign Prostatic Hyperplasia.
The Manufacturer and User Facility Device Experience database was queried for "Aquablation, Greenlight Laser, Holmium Laser, Morcellator, Water Vapor Thermal Therapy, Loop Resection, and Prostatic Urethral Lift" from 2018 through 2021. A complication classification system (Level I-IV) based on the Clavien-Dindo system was used to categorize events. These events were then correlated with procedural technology malfunctions and classified as "device related" and "non-device related." Chi squared analysis was performed to identify associations between procedural technology and complication classification distribution.
A total of 873 adverse events were identified. The adverse events were classified into level I (minimal harm) versus levels II-IV (clinically significant). Aquablation (p < 0.017) and Water Vapor Thermal Therapy (p < 0.012) were associated with a higher proportion of reports with Level II-IV complications compared with other procedure types. Level II-IV complications were not associated with a reported device related malfunction.
Aquablation and water vapor thermal therapy demonstrated noteworthy clinically significant complications which were not driven by device-related malfunctions.
