ABU Qualifying Exam study guide
ABU Qualifying Exam · Work through your exam, one topic at a time.
The American Board of Urology (ABU) Qualifying Examination, also called Part 1, is the first step in the ABU initial certification process. Its stated purpose is to determine whether a candidate demonstrates the minimum level of knowledge a panel of experts considers necessary for the safe practice of urology. It is aimed at residents who have met the ABU's pre-urology training requirements and completed at least six months of chief residency in an approved U.S. or Canadian program by June 30 of the exam year. Topics on this exam: Physiology, immunology, molecular biology, hypertension, transplantation, sexual dysfunction, voiding dysfunction, Infections, inflammatory diseases, endocrinopathy, calculus disease, trauma, obstructive uropathy, fertility, Neoplasms, urinary diversion, fistulae, and Pediatric urology, anatomy, fluid and electrolyte disorders. The ABU Qualifying Exam study guide has 4 sections and about 4,062 words.
01Physiology
Focus on renal physiology as an integrative system: glomerular filtration (Starling forces, filtration fraction), tubular handling of sodium and water, countercurrent multiplication and the loop of Henle, and hormonal control via renin-angiotensin-aldosterone, ADH, and ANP. Understand acid-base handling (bicarbonate reabsorption, titratable acid, ammonia) and potassium distribution between intracellular and extracellular compartments.
263 words, about 1 min02Immunology
Understand innate versus adaptive immunity, antigen presentation (MHC I to CD8, MHC II to CD4), T-cell subsets (Th1, Th2, Th17, Treg), and B-cell antibody production. Know complement pathways and the clinical meaning of complement levels.
254 words, about 1 min03Molecular Biology
Master the central dogma: replication, transcription, translation, and post-translational modification. Know DNA repair mechanisms, oncogene versus tumor suppressor logic (activation vs loss of function), and the two-hit hypothesis.
236 words, about 1 min04Hypertension
Understand primary versus secondary hypertension, with emphasis on renal and endocrine causes relevant to urology: renal artery stenosis, pheochromocytoma, primary aldosteronism, and renin-secreting tumors. Know the renin-angiotensin-aldosterone axis and how each antihypertensive class acts.
