Neurological Surgery Residency

About the Program

Dr. Menezes teaching resident in clinicThe seven-year neurosurgical residency program at the University of Iowa is designed specifically to prepare residents for a career as senior surgeon-scientists, and future leaders in the field of academic neurosurgery. It is the intent of this seven-year training program to develop world class neurosurgeons.

Residents completing the program will be eligible for certification by the American Board of Neurological Surgery (ABNS) with a goal of a 100 % pass rate on both the qualifying and the certifying examinations. Categorical residents are required to pass the written examination for primary certification, prior to becoming chief resident. Visit the American Board of Neurosurgical Surgery for specifics on board certification requirements.

Clinical competencies

To attain these goals, the program requires residents to develop the following competencies:

  1. A solid foundation of basic and clinical knowledge of neurosurgery.
  2. The ability to provide compassionate and effective care to all patients.
  3. The ability to perform general neurosurgical procedures safely and effectively.
  4. The exercise of clinical judgment to critically select the appropriate course of action in the management of patients.
  5. The capacity to communicate effectively with all healthcare personnel and with patients.
  6. Knowledge about established and emerging biomedical, clinical and cognitive sciences, and the application of this knowledge to neurosurgical patient care.
  7. Ability to analyze practice experience and perform practice-based improvement activities using a systematic methodology.
  8. Apply knowledge of study designs and statistical methodology to the appraisal of clinical studies and information regarding diagnostic and therapeutic effectiveness.
  9. A demonstrated commitment to carrying out professional and administrative duties, adherence to ethical principles and sensitivity of diverse patient populations, required in the surgical profession.
  10. The constant pursuit of improvement in patient care practices by systematic evaluation of current practices in relation to outcomes and to new scientific knowledge.
  11. An awareness of and responsiveness to the underpinnings of the health care system, and the dilemmas of practicing healthcare that is of optimal value and cost effective.

Residents are expected to develop these elements of clinical competence by doing the following:

  • Assimilating the teaching provided by the faculty
  • Maintaining an active reading plan for neurosurgical sciences
  • Practicing their clinical/surgical skills
  • Attending the educational activities offered by the residency program


During the seven years of intensive training, each of the above elements of clinical competence is periodically assessed by direct faculty supervision and by senior resident colleagues with subsequent review by the program director. Re-appointment and promotion to the subsequent PGY year requires a satisfactory progression in the development of these elements of clinical competence.

The educational program of the residency is designed to meet specific goals and objectives at each level of training as outlined in the following table. The program is designed in accordance with the ACGME core competencies. RRC requirements can be found on the ACGME Neurological Surgery site.

PGY by Year

two residents


During the PGY 1 year the resident spends six months on the neurosurgical service taking care of patients on the neurosurgical floor and getting early exposure to the operating room Residents learn the following in their first year:

  • Preoperative medical work-up for neurosurgical patients
  • Postoperative care & critical care management of the neurosurgical patient
  • Complex socioeconomic factors related to disposition

In addition to inpatient care, the resident is expected to become comfortable in operating room. Under the supervision of faculty and senior residents, the PGY-1 resident will be expected to become proficient with the following:

  • Positioning & Equipment Setup
  • Standard opening & closing of cranial & spinal procedures
  • Basic operative technique
  • Ventriculostomy Placement
  • Intracranial Pressure Monitor Placement
  • Lumbar Drain Placement

PGY 1 residents take "buddy call" with the PGY 2 and 3 residents and, in a graduated fashion, learn the structure, organization, and work-up necessary for being the independent on-call resident.

Off-service rotations

The remainder of the PGY 1 year is spent on off service rotations providing exposure to services that work closely with the neurosurgical service, cultivating a deeper understanding and appreciation for the overall care of the patients that we manage.

These include:

  • Trauma surgery
  • Stroke neurology
  • Neuroendovascular Surgery (working in the angiography suite with Neurosurgery/Neurology/Radiology)
  • Neuro-otology (exposure to lateral skull base approaches)
  • Neuro-ophthalmology
  • Surgical-Neurological ICU

PGY-2 and PGY-3 (18 months on inpatient service)

During the PGY 2 and 3 years, residents are fully integrated into the neurosurgical service and assume the role of “junior resident,” including primary call responsibility, graduated autonomy in the operating room, and management of the inpatient service. 

Junior resident call is a 24-hour in-house call that, on average, is taken every 4 days. During the on-call period, the resident is responsible for every aspect of the neurosurgical service, allowing the resident to develop extensive knowledge and experience caring for critically ill patients on our service

Resident responsibilities

This includes the following responsibilities:

  • Knowing the neurologic exam and plan for every patient on the neurosurgical service
  • Reviewing the imaging studies acquired on such patients
  • Evaluating patients postoperatively
  • Seeing new consults in the emergency room

Promptly to any questions/pages regarding any patient on the neurosurgery service

During this time, each resident is also assigned to a primary service, with each rotation consisting of a 6-month block.

These include:

  • Intensive Care Unit (ICU) patients
  • Pediatric Neurosurgical patients
  • Neurosurgery consultation patients

In the operating room, the junior resident continues to advance their operative skills, gaining progressive autonomy in increasingly complex procedures under the supervision of the attending neurosurgeon. This includes exposure to vascular neurosurgery, neuro-oncology, epilepsy surgery, complex spine surgery, and functional neurosurgery, peripheral nerve surgery, and endovascular neurosurgery.

PGY-3 – 6 months on Continuity of Care (CoC) rotation

During this 6-month rotation the resident begins to transition into a more senior resident role with an independent block with two faculty, Hiroyuki Oya, MD, PhD, and Satoshi Yamaguchi, MD, PhD.

The resident will be paired with these faculty in a “mentorship model” in which they follow their patients from clinic, to the operating room, and to follow-up.

During this time, the resident spends two days a week in the clinic with these faculty evaluating patients and then is able to follow these patients through their entire interaction with the neurosurgical service.

This time allows the resident to gain further experience in the following areas.

  • Outpatient evaluation of neurosurgical disease
  • Patient History & Physical
  • Imaging assessment
  • Formulating a surgical plan & discuss management strategies
  • Ongoing evaluation & management of neurosurgical patients
  • Review procedures and consent information with patients
  • Perform operate procedures with faculty oversight
  • Round on and manage postoperative patients
  • Patient follow-up in clinic after discharge

This rotation has been invaluable to the education of the neurosurgical resident in allowing them to gain a greater appreciation of the entire scope of patient care as they move toward independent practice, from outpatient evaluation, surgical intervention, and follow-up care. Focused mentorship during this time also allows the resident to gain autonomy in patient management as well as in the operating room, allowing significant advancement in operative skill.

PGY-4 and PGY-5 – 2 years of research time

After completion of the junior resident years, the transition to senior residency begins with two years of dedicated research time.

During the initial three years, it is expected that the resident has explored research opportunities and begun working with neurosurgical faculty and colleagues in both the clinical and basic science realms to establish a collaborative research plan.

The goal during this two-year period is to allow the resident dedicated time to be immersed in rigorous scientific research and acquire the skills necessary for a lifelong career as an academic surgeon scientist. Time should be spent executing experiments, analyzing data, and preparing manuscripts for publication.

Clinical responsibilities

Clinical obligations during this time are limited, with the resident covering “chief call” on average 1 of 4 weekends. This involves rounding with the team that weekend and taking home call while supervising the in-house junior resident on call.

All operative procedures during this call period are performed by the resident on “chief call” in conjunction with the attending on call.

PGY-6 - Chief Year

The chief residency year is divided into two six-month blocks during which the chief resident is assigned half of the neurosurgical service based on faculty member. The chief acts as the primary physician responsible for managing all aspects of neurosurgical patient care.

Responsibilities of the chief resident include:

  • Rounding on all patients
  • Formulating care plans, even for the most complex neurosurgical patients
  • Formulating operative plans
  • Overseeing the care provided by junior residents
  • Providing operative coverage for elective and emergent cases daily
  • Alternating call every other day to direct care of new consults

Upon completion of this year under the supervision of the neurosurgical faculty, the chief resident should be prepared to practice and operate independently as they transition independent practice.

PGY-7 – Transition to Practice

During the PGY-7 year, the resident spends six months at the University of Iowa where they will see patients in their own clinic and to formulate clinical and operative plans independently. These patients will be staffed with a supervising faculty member who ultimately is responsible for the case, however it is the expectation that the PGY-7 resident acts as the treating physician. 

Buddy call

In addition to the elective outpatient service, the resident also will take "buddy" faculty call to further the transition to practice experience, allowing for independent decision making regarding operative management.  Moreover, the PGY 7 resident is available to operate on any of the elective patients on the operative schedule to allow the trainee to further hone their operative skills in an independent, but mentored environment.

Off-site rotation

The other six months of the PGY-7 year is designed to allow the resident additional training in their field of choice. This is frequently done off site at another institution, however if desired the resident may also stay at the University of Iowa and work with any of the faculty in a one-on-one fashion to continue to develop skills of interest.

These experiences are typically arranged independently by the resident prior to their chief year with the guidance of faculty.  During this period, the resident is provided with a living expense stipend in addition to their current salary and benefits to offset the cost, allowing the pursuit of additional training in their subspecialty area of focus.

Overall, this has been an invaluable experience during this final year, allowing for significant professional and personal growth.

PGY-7 Elective Opportunities

Jermee Greenlee teaching resient

During the PGY-7 year, residents can spend six months at a location of their choice getting additional training in an area of interest. This may be done off-site or at the University of Iowa and is setup independently by each resident with the guidance of faculty.

“When choosing the neurosurgery residency program at Iowa, I was struck by the types of cases the chief residents described being able to do own their own and the team-based mentality the residents seemed to have. Having been in the program for several years now, I still am struck by the fantastic training with high clinical volume, hands-on operative experience, and extensive research opportunities. The residents have a great team-based mentality and camaraderie that make the challenges of neurosurgery enjoyable. My wife and I love living in Iowa and it is a wonderful place to raise our three young children. I would absolutely choose Iowa again.”

“Having had the chance to pursue a post-doctoral fellowship in the Department of Neurosurgery at the University of Iowa, I was able to witness firsthand the cutting-edge scientific research and world class patient care that is rendered to our patients on a day to day basis. The diverse array of clinical presentations as well as volume of operative cases was also unparalleled. In addition, the utmost emphasis in training future academic neurosurgeons, who are leaders in their respective subspecialties along with the camaraderie and friendship among the residents, made choosing Iowa neurosurgery training program an easy choice.”

Clinical and research interests

I have keen interest in pursuing novel treatment approaches and research in the field of neuro-oncology, particularly in immunotherapy and the role of nanotechnology in the design and delivery of cell-specific anticancer molecule and their effect in GBM tumor kinetics.

“During my sub-internships around the country, I was impressed with the uniform consensus around the excellent track record of producing well trained academic neurosurgeons at the University of Iowa.  During my interview at the University of Iowa, I was struck by the enthusiasm for and commitment to structured resident mentorship by Dr. Howard and Dr. Greenlee, as well as the two dedicated years for research which can take place anywhere in the world. After ranking Iowa highly and being fortunate enough to match here, I can say with confidence that if being an academic neurosurgeon is your career goal, then the University of Iowa should be a program on your radar.”
