CURN Exam Domains 2026: Complete Guide to All 11 Content Areas

How the 11 Content Areas Fit Together: Two Axes, Not One List

The Certified Urologic Registered Nurse (CURN) examination, offered by the Certification Board for Urologic Nurses and Associates (CBUNA), is built on an official blueprint adopted in October 2017 and effective October 2018. That blueprint is still the one posted on CBUNA's current Exam Details page and reproduced in the full 2025 handbook. If you have seen the phrase "11 content areas," it refers to the number of published categories across the blueprint, and understanding how those categories relate is the first step in studying efficiently.

The 11 categories are divided into two axes:

• Axis I, Patient Problems (Domains 1 through 6): what condition or clinical situation the question is about.
• Axis II, Nursing Activities (Domains 7 through 11): what the nurse is being asked to do about it.

Every exam question is classified on both axes, and each axis independently totals 100%. That means you should never add all 11 percentages together; doing so would double-count the examination. A question about a patient with an obstructing ureteral stone, for example, might sit in Domain 4 on the patient-problem axis and in Domain 7 (assessment and monitoring) or Domain 9 (patient teaching) on the activity axis.

For a broader walkthrough of how to turn the blueprint into a plan, see the CURN Study Guide 2026: How to Pass on Your First Attempt. This article focuses on what each domain contains and how heavily it is weighted.

Axis I: The Six Patient-Problem Domains

Domain 4: Obstructive Uropathies and Trauma, Including Stones and BPH (25%)

This is the heaviest patient-problem category, and it is broad. It covers conditions in which urine flow is blocked or the urinary tract is injured, and the blueprint explicitly names stones and benign prostatic hyperplasia (BPH).

Domain 3: Voiding Dysfunctions, Including Incontinence (24%)

Domain 3 is the second-largest patient-problem area and the one most tied to everyday urologic nursing practice. It covers problems with storage and emptying of urine, including the different types of incontinence.

Domain 6: Genitourinary Cancers (23%)

At 23%, genitourinary cancers carry nearly as much weight as voiding dysfunctions. Expect questions across the major urologic malignancies, including their presentation, staging concepts, treatment modalities, and the nursing care that accompanies each.

Domain 2: Urinary Tract Inflammations and Disorders (18%)

This domain addresses infections and inflammatory conditions of the urinary tract. Catheter-associated infection prevention, cystitis and pyelonephritis, and related disorders are natural fits.

Domain 1: Pediatric Anomalies, Embryology, and Common Pediatric Neoplasms (5%)

One of the two smallest categories, but it still contributes questions. It covers congenital anomalies of the urinary tract, the embryologic basis for them, and the more common pediatric tumors. Because the weight is small, aim for solid recognition of the major anomalies rather than deep subspecialty detail.

Domain 5: Infertility and Sexual Dysfunctions, Disorders of Male Genitalia (5%)

The other 5% category. It spans male infertility, sexual dysfunction, and disorders of the male genitalia. Know the common causes, basic evaluation approaches, and treatment categories, along with the sensitivity required when counseling patients on these topics.

Axis II: The Five Nursing-Activity Domains

Axis II describes what you do as a nurse, regardless of the specific condition. Because every question is tagged on this axis too, these domains show up inside nearly every scenario you will see.

Domain 8: Plan and Implement Care (30%)

The single largest category on the entire blueprint. It covers developing and carrying out care for patients with urologic conditions and procedures or treatments. In practice, this is where the exam asks you what you would actually do: which intervention comes next, how to manage a catheter or drain, how to prepare a patient for a procedure, or how to respond to a complication.

Domain 7: Assess and Monitor (25%)

Assessment questions ask what you would evaluate, what findings matter, and what changes warrant escalation. Expect scenarios built around intake and output, pain, urine characteristics, postoperative monitoring, and recognizing early signs of deterioration.

Domain 9: Teach Patients, Significant Others, Other Health Professionals, and the Public (25%)

Teaching is weighted equally with assessment, which surprises many candidates. This domain covers education on prevention and management of urologic conditions, directed not only at patients but also at families, colleagues, and the public. Practice identifying the teaching point that is most important, most accurate, or most appropriate for a given audience.

Domain 10: Evaluate Outcomes of Care (12%)

Evaluation questions ask whether an intervention worked and what to do if it did not. Know the expected outcomes for common treatments and the indicators that tell you a plan needs revision.

Domain 11: Ensure Professional Practice (8%)

The smallest activity domain addresses promoting patient outcomes through consultation, staff development, quality improvement, and research. It is a modest slice, but it is also among the most learnable: questions tend to test whether you understand professional responsibilities rather than clinical detail.

Domain Weights at a Glance

Each axis sums to 100% on its own. Notice that on Axis I, Domains 3, 4, and 6 together make up 72% of the content, which tells you where the bulk of your clinical review time belongs. On Axis II, Domains 7, 8, and 9 together make up 80%.

Exam Format, Timing, and What the Questions Look Like

The CURN exam consists of 150 single-best-answer multiple-choice questions, and that total includes unscored pilot items that CBUNA uses to evaluate future questions. You will not know which items are unscored, so treat every question as if it counts. You have 3 hours to complete the exam, which works out to a little over a minute per question. There is no guessing penalty, so never leave an item blank.

The passing standard is 70%, established through the Angoff procedure, a method in which subject-matter experts judge how a minimally qualified candidate would perform on each item. For a deeper explanation of how scoring is framed, see CURN Passing Score 2026: Exactly What You Need to Pass.

Because every question carries two classifications, a typical item is a short clinical scenario that asks you to apply a nursing action to a urologic problem. Expect stems that describe a patient, a condition, and a situation, followed by four options in which one is the best answer. "Best" often means most appropriate or highest priority, so more than one option may sound reasonable.

Sequencing Your Review by Domain Weight

The only general study advice worth including here is how to order the domains. Because the blueprint is weighted, review should be too: start with the heaviest areas, and fold the Axis II activities into every clinical week rather than treating them separately.

Adjust the length to your own calendar and experience. A nurse who works daily in a stone clinic will move through Domain 4 faster than one whose practice centers on oncology.

Eligibility, Fees, and Registration Mechanics

Before you worry about domains, confirm you qualify. U.S. applicants need:

• Completion of a nationally accredited nursing program
• Two years of RN experience
• At least 800 clinical urologic patient-care hours within the preceding three years
• A current, active, unrestricted RN license in the United States or its territories

International applicants must show approved nursing education and practice experience plus first-level general nursing registration. The exam is administered in English, and CBUNA may review transcripts. The full breakdown is in CURN Requirements 2026: Eligibility, Prerequisites & How to Qualify.

SUNA membership is optional, and the member discount is the only difference in the fee structure. The costs add up differently depending on whether you retake or renew by contact hours, which is covered in CURN Certification Cost 2026: Complete Pricing Breakdown.

Certification lasts three years and expires on December 31 of the renewal year. To recertify you need current licensure and CBUNA certification, 800 hours of urologic practice during the certification period, and either reexamination or 36 approved urology contact hours earned in that period (no more than 10 of them nephrology hours). Because nephrology hours are capped, build your continuing education around urology topics from the start. If you are weighing the investment, see Is the CURN Certification Worth It?

A Note on Accreditation and Current Delivery Details

Two points deserve transparency so you can make an informed decision.

Accreditation. CBUNA's FAQ reports that the CURN program's ABSNC accreditation lapsed in 2025 and that reinstatement was in progress as of March 2026. No subsequent reinstatement was verified when this article's sources were checked, and ABSNC's current directory lists the CUNP credential but not CURN. CBUNA continues to accept CURN exam applications. If accreditation status matters to your employer or your plans, confirm the current status directly with CBUNA and ABSNC before you apply.

Delivery. Current CBUNA notices identify CMS as the testing agency and describe fully remote examinations after application review. Some older materials, including the March 2025 handbook, legacy C-NET and PSI pages, and certain recertification wording, still describe testing-center instructions. Follow the current application and scheduling instructions from CBUNA rather than relying on older pages. Scheduling windows and deadlines are covered in CURN Exam Dates 2026: Testing Windows, Deadlines & Scheduling.
