Genitourinary Pathology

Genitourinary (GU) Pathology at Northwestern has been established as a program of excellence since 2006, with leading national experts. Clinically, urologic service is very active and high volume. We work closely with clinical colleagues to provide the best service for patients and the best training for our residents and fellows.


We offer one, 1-year non-ACGME accredited fellowship. Fellows have sign-out privileges of highly complex cases. Please visit the GU Fellowship page for further details. GU cases are reviewed daily during quality assurance meetings with Surgical Pathology faculty. Inter-departmental conferences are held regularly for residents and fellows rotating in anatomic pathology.  Our residents and fellows will also present cases in the GU tumor boards biweekly to discuss clinical management. Since its launch, 12 pathologists have completed their GU fellowship training in this program.


The division has a strong tradition of prostate cancer research. Multiple research projects are ongoing, particularly for studies of the prostate, bladder, and kidney cancers. Work is done in collaboration with clinical colleagues and research scientists at the Lurie Cancer Center and investigators from Specialized Program of Research Excellence (SPORE) of prostate cancer.

Patient Care and Consultations

More than 4,000 GU in-house cases are reviewed annually, including over 1,500 prostate cases and a wide range of benign and malignant conditions of the bladder, kidney, adrenal, testis, urethra and penis.  Additionally, faculty review consultation cases from NM affiliates and other institutions to provide state-of-the-art diagnoses and expertise for challenging GU conditions.
