PAVE QSE Reproductive and Urinary Review (IRIS 2026)

Reproductive and Urinary is the ninth body-system subcategory in Domain 2 of the AAVSB's 2027 Qualifying Science Examination (QSE) outline. It covers kidney disease, the lower urinary tract, theriogenology and the mammary gland across every species seen in North American practice. The highest-yield material is the International Renal Interest Society (IRIS) kidney staging, which was revised in 2026, plus a short list of classic emergencies: the blocked cat, pyometra, dystocia, milk fever and pregnancy toxemia. This review gives you the facts you need for each, checked against IRIS and the Merck Veterinary Manual.

This guide is part of our Veterinary Medicine by System guide, which sits under the main QSE study guide for 2027.

Where This Topic Sits in the 2027 QSE Outline

The 2027 outline, used from the January 2027 exam date, lists "I. Reproductive and Urinary" under Domain 2, "Veterinary Medicine by System Including Pathology, Diagnosis, Treatment, and Prevention". The AAVSB gives question counts for each domain (54, 93 and 8, a total of 155) but not for each subcategory, so nobody can tell you exactly how many reproductive or urinary questions you will see. What the domain title does tell you is the angle: expect questions on how a disease develops, how you confirm it, how you treat it and how you prevent it.
