Payments from drug & device makers
What this record shows
This record is dominated by royalties or licence payments: $731,388 of the $731,663 with a category attached, or 100.0%. Mission Pharmacal Company accounts for 100.0% of it on its own, with 5 other manufacturers making up the rest. Reporting peaked in 2020 at $183,557 and has fallen 56.3% since, to $80,264 in 2025. Among urology clinicians in TX with any reported payments, this total sits in the top 5% — high for the specialty, which is a reason to read the composition above rather than the number alone.
Across 34 payments — averaging $21,520 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

What the payments were tied to
Products named in the reported payments. Only payments of $100 or more are attributed here — the typical reported payment nationally is a meal worth about $16, and listing those product-by-product would be noise.
