Purpose: We sought to describe and analyze the adverse events associated with synthetic male slings reported to the U.S. Food and Drug Administration (FDA) Manufacturer and User Facility Device Experience (MAUDE) database. Methods: We queried the MAUDE database for all entries including the terms “Male Sling,” “InVance,” “Virtue,” or “Advance” from January 1st, 2009 to December 31st, 2018. We collected and analyzed information about the event type, date received, report source, source type, and manufacturer. We reviewed and categorized the event description text for each medical device report (MDR). Results: A total of 497 adverse events related to the male sling were identified. The adverse events were classified as injury (95.4%), malfunction (4.2%), and other (0.4%). There were no deaths described. The slings involved were the Advance or Advance XP sling (69.8%), InVance (15.5%), Virtue Quadratic (12.3%), or unknown (2.4%). The 4 most common adverse events described were urinary incontinence (46.7%), sling erosion (9.1%), mechanical malfunction (8.2%), and pain/numbness (8.2%). There was no increase in the number of reports in the years following the FDA warnings for urogynecologic mesh. Conclusions: There was an overall modest number of MDRs related to male slings and the majority of them were reported by the manufacturer. The reporting of adverse events for male slings does not seem to be affected by the controversy and scrutiny towards transvaginal mesh and midurethral slings. Further clinical studies and more objective and detailed databases are needed to investigate the safety of these synthetic slings.

<P/><P>Interstitial cystitis/painful bladder syndrome (IC) is a chronic syndrome of unknown etiology that presents with bladder pain, urinary frequency, and urgency. The lack of specific biomarkers and a poor understanding of underlying molecular mechanisms present challenges for disease diagnosis and therapy. The goals of this study were to identify noninvasive biomarker candidates for IC from urine specimens and to potentially gain new insight into disease mechanisms using a nuclear magnetic resonance (NMR)-based global metabolomics analysis of urine from female IC patients and controls. Principal component analysis (PCA) suggested that the urinary metabolome of IC and controls was clearly different, with 140 NMR peaks significantly altered in IC patients (FDR < 0.05) compared to that in controls. On the basis of strong correlation scores, fifteen metabolite peaks were nominated as the strongest signature of IC. Among those signals that were higher in the IC group, three peaks were annotated as tyramine, the pain-related neuromodulator. Two peaks were annotated as 2-oxoglutarate. Levels of tyramine and 2-oxoglutarate were significantly elevated in urine specimens of IC subjects. An independent analysis using mass spectrometry also showed significantly increased levels of tyramine and 2-oxoglutarate in IC patients compared to controls. Functional studies showed that 2-oxoglutarate, but not tyramine, retarded growth of normal bladder epithelial cells. These preliminary findings suggest that analysis of urine metabolites has promise in biomarker development in the context of IC.</P>
