Abstract
Purpose
MAUDE database houses medical device reports of suspected device-related complications received by Food and Drug Administration. In the present study we aim to evaluate the MAUDE database for reported complications of MIST procedures.
Methods
The database was queried using keywords: rezum, urolift, prostate embolization (PAE), transurethral needle ablation (TUNA), transurethral microwave therapy (TUMT), prostate stent and Temporarily Implanted Nitinol Device (iTIND) on 10/1/22 to extract information regarding device problems and procedure-related complications. Gupta classification system was used to stratify complications. Statistical analysis was performed to compare frequency of complications among MIST procedures.
Results
We found a total of 692 reports (Rezum-358, urolift-226, PAE-53, TUNA-31, TUMT-19, prostatic stent-4, and iTIND-1). Most complications related to device or users were minor (level 1 and 2) and there was no significant difference among various MIST procedures. The screen/system error was responsible for 93% and 83% aborted cases in Rezum and TUNA, respectively, and PAE showed 40% of device component detachment/fracture. Overall Urolift and TUMT were associated with statistically significant higher incidence of major (level 3 and 4) complications (23% and 21%, respectively) as compared with Rezum (7%). Most major complications needing hospitalization after Urolift included hematoma and hematuria with clots and those after Rezum included urinary tract infection and sepsis. Thirteen deaths were reported, mostly due to cardiovascular events, which were classified as not associated with the proposed treatment.
Conclusion
MIST for BPH can occasionally cause significant morbidity. Our data should assist urologists and patients in shared decision-making process.
