Largest urology physician group practices
Urologists are specialists in caring for conditions involving the genitourinary system, which include conditions affecting the bladder, kidneys, ureters, urethra, and pelvic floor.
From the integration of advanced surgical technologies to the expansion of outpatient and value-based care models, urologists and urology practices are adapting rapidly to meet rising patient demand and shifting reimbursement landscapes.
How many urology physician group practices are there in the U.S.?
Definitive Healthcare defines a physician group as one or more physicians operating as an organization to provide patient care. The main specialty is determined by the most common specialty of the physicians listed for that practice. It’s important to note that physician group practices, especially large ones often have several different locations and physicians specializing in different fields of medicine, to reach more patients and remain competitive. Because of this, the number of physician group practices does not reflect the number of urology practices in the United States that only practice urology as its main specialty.
Below, we used data from our PhysicianGroupView product to look at the top physician group practices with urology listed as its main specialty.

What is the largest urology physician group in the U.S.?
The list above ranks the largest urologist physician group practices active in the U.S. as of December 2025.
Suburban Community Hospital Physicians stands out as a clear outlier, employing 224 urologists, more than 80 physicians larger than the second-ranked group. This significant scale suggests a dominant regional footprint and substantial operational complexity, likely supported by strong referral networks, hospital affiliations, and diversified service offerings.
Below the top-ranked group, a second tier of large, multi-site practices emerges, including GenesisCare, Chesapeake Urology, and MidLantic Urology, each employing between 100 and 140 urologists.
Geographically, the largest urology groups are concentrated in dense, high-demand markets such as the Mid-Atlantic, Northeast, and Southeast. Pennsylvania and New York, in particular, appear multiple times in the top 15, underscoring how population density, aging demographics, and competitive healthcare markets drive consolidation.
Why urology group size matters for commercial strategy
Urology group size is a critical input for commercial strategy because it directly shapes buying power, decision-making complexity, growth potential, and go-to-market approach. Generally speaking, scale often determines how and how fast vendors can win and expand accounts.
Larger urology groups often concentrate purchasing authority and revenue opportunity. A single large group with 80–200+ urologists can represent dozens of practice locations, surgery centers, and imaging sites under one contracting umbrella. For commercial teams, this means fewer accounts can drive a disproportionate share of revenue. Winning one enterprise-level urology group can unlock multi-site adoption, standardized product use, and long-term contracts that would otherwise require years of individual practice selling.
Scale also often correlates with service line breadth and growth readiness. Larger urology groups are more likely to offer advanced procedures, operate ambulatory surgery centers, employ ancillary services like imaging and pathology, and participate in value-based or risk-bearing arrangements.
