Perception vs. Reality: Assessing Knowledge Gaps in Urinary Stone Management Among Medical Trainees and Junior Physicians
This study of 407 Saudi medical trainees and junior physicians reveals that while factual knowledge about urinary stone management is often adequate, a significant gap exists between actual competence and self-perception, characterized primarily by widespread under-confidence that worsens with time after graduation.

Kidney stones are a common and painful medical problem, occurring when hard mineral deposits form inside the kidneys. In many parts of the world, including Saudi Arabia, these stones are a frequent reason people visit doctors. There are two main types of stones that clinicians encounter, and they behave very differently. One type, made of calcium oxalate, is hard and stubborn; it cannot be dissolved by changing the chemistry of the urine. The other type, made of uric acid, is more flexible; it can often be broken down and flushed out simply by making the urine less acidic. Because the treatments are so different, a doctor must be able to tell them apart quickly. If a doctor mistakes a dissolvable stone for a stubborn one, a patient might undergo unnecessary surgery. If the mistake goes the other way, a patient might miss a chance to avoid an operation.
In hospitals and emergency rooms, the first doctors to see these patients are often not senior specialists, but rather medical students in their final years of school, recent graduates working as interns, or general practitioners. These junior clinicians are responsible for ordering the initial scans and deciding whether to send the patient to a specialist or treat them right away. A critical question for patient safety is whether these early-career doctors actually know the difference between the stone types, and whether they are confident enough in their knowledge to make the right call. A new study from Riyadh, Saudi Arabia, set out to measure exactly this gap between what these young doctors think they know and what they actually know.
The researchers gathered a large group of 407 participants from medical schools and hospitals in the Riyadh region. This group included final-year medical students, interns, and general practitioners. The team asked these doctors to fill out a digital questionnaire that tested two things. First, it asked them to rate their own confidence and experience with kidney stones. Second, it asked them specific, factual questions about how the stones form, how they appear on computerized tomography scans, and which ones can be dissolved with medicine. The goal was to compare their self-assessment against their actual test scores to see if they were overconfident, underconfident, or accurately calibrated.
The results revealed a surprising pattern. While a significant portion of the participants, about 41 percent, actually demonstrated good factual knowledge on the test, only a tiny fraction, just 6.6 percent, believed they were good at the subject. In other words, most of these young doctors knew more than they gave themselves credit for. They tended to underestimate their own abilities rather than overestimate them. This lack of confidence was most pronounced among the medical students, who scored the highest on the factual questions but rated their own knowledge the lowest. As the doctors gained more clinical experience, moving from student to intern to general practitioner, their self-confidence grew, bringing their self-assessment closer to their actual performance, though their factual knowledge did not necessarily improve with time.
When the researchers looked at specific facts, the doctors performed well on some topics but struggled with others. They correctly understood that uric acid stones could be dissolved and that the density of a stone on a scan was important for planning treatment. However, they often failed to recognize that calcium oxalate stones cannot be dissolved by medication, a crucial detail that could lead to unnecessary delays in treatment. The study also found that age played a role in knowledge retention. Doctors in the older age group tested in the study, those between 34 and 40 years old, scored significantly lower on factual questions than the younger participants, suggesting that knowledge gained in medical school can fade if it is not regularly used or reinforced.
The study concludes that the main problem for these junior clinicians is not a lack of information, but a lack of confidence in the information they possess. The doctors are often capable of making the right decisions but hesitate to do so because they doubt their own judgment. This hesitation can lead to delays in care or the ordering of unnecessary tests. The authors suggest that medical training needs to change to address this. Instead of just teaching facts, educators should provide more case-based learning and feedback that helps students and junior doctors align their confidence with their actual skills. By building both knowledge and the confidence to use it, the medical community can help ensure that patients receive the correct treatment for their kidney stones without unnecessary delay or error.
