Chronic kidney disease affects hundreds of millions of people worldwide, yet public awareness of kidney health remains remarkably low compared to other major conditions. Events like the Budapest Nephrology School, recently hosted at Semmelweis University in Hungary, play a vital role in closing that gap by training the physicians and researchers who will shape the future of kidney research and kidney disease prevention.
This year marked a milestone: the 30th edition of the Budapest Nephrology School, a five-day intensive program organized by the Hungarian Kidney Foundation from 24 to 28 August. It drew 111 participants from 31 countries, including specialists from Australia, Bulgaria, Croatia, Japan, Mozambique, Singapore, and the United Kingdom. Since its founding in 1993, the school has hosted physicians and researchers from 70 countries, earning recognition and support from the European Renal Association (ERA) and the International Society of Nephrology (ISN).
For medical students, young nephrologists, and researchers considering a career in kidney medicine, the event offers a useful case study in how high-quality postgraduate education is built. Below, we examine what made this anniversary edition significant, the science it covered, and what aspiring nephrologists can take away from Hungary’s flagship nephrology training course.
Why the Budapest Nephrology School Matters for Global Kidney Research
Few continuing medical education programs achieve the longevity and international reach of the Budapest Nephrology School. Running annually for three decades, it has grown into one of Europe’s leading nephrology training courses, attracting a faculty and student body that spans continents.
Several factors explain its enduring appeal:
- Institutional backing: Recognition from the ERA and ISN signals that the curriculum meets rigorous international standards.
- A bridge between lab and clinic: The program deliberately spans laboratory research and clinical practice, so participants leave with both scientific depth and practical applicability.
- Accessibility for young researchers: In keeping with tradition, students and staff at Semmelweis University registered for the course free of charge, lowering the barrier for early-career engagement with the international nephrology community.
- A historic setting: Lectures took place at Semmelweis University, Hungary’s oldest medical school, with a public session held in the Grand Hall of the Hungarian Academy of Sciences.
For anyone weighing where to pursue nephrology training or research collaboration in Central Europe, the school’s track record speaks for itself.

Key Scientific Themes: From Salt Intake to Kidney Regeneration
The five-day scientific program tackled questions at the frontier of nephrology. Understanding these themes is valuable not only for specialists but also for general practitioners and medical students who encounter kidney disease in everyday practice.
Nutrition and Kidney Function
Lectures examined how salt and potassium intake affect kidney function, a topic with direct implications for kidney disease prevention. Dietary sodium excess drives hypertension, which in turn accelerates kidney damage, while potassium management is a daily concern for patients with reduced kidney function. These sessions reinforced a message that prevention efforts worldwide are increasingly emphasizing: dietary interventions are among the most cost-effective tools in nephrology.
Immune-Mediated Kidney Disease
Speakers discussed how kidney diseases linked to immune system dysfunction can be identified and treated. Autoimmune conditions affecting the kidneys often present diagnostic challenges, and advances in immunosuppressive therapies are rapidly changing treatment standards. Keeping pace with these developments requires exactly the kind of concentrated, expert-led format the Budapest Nephrology School provides.
Kidney Tissue Regeneration
One of the most forward-looking topics was the mechanisms that may help kidney tissue regenerate. The kidney has limited intrinsic regenerative capacity compared to organs like the liver, so research into cellular repair pathways holds significant promise for future therapies. This area was highlighted in the public lecture by János Peti-Peterdi, a research professor based in Los Angeles, who emphasized both the prevalence of kidney disease and the importance of prevention.
Cognitive Decline and Chronic Kidney Disease
The connection between kidney disease and cognitive decline is an emerging concern in kidney research. As patients live longer with chronic kidney disease (CKD), clinicians must account for its effects beyond the kidneys themselves, including brain health. Sessions on the early detection of CKD and the difficult-to-treat high blood pressure associated with it underscored how much diagnostic practice is evolving.
These topics illustrate a broader truth for anyone entering nephrology: the field sits at the intersection of internal medicine, immunology, transplantation, and public health. Prospective students who want to build a foundation in these areas can explore the study programs and research opportunities available at Semmelweis University, where much of this science is taught and practiced.
Transplantation Science: New Frontiers in Donor Matching and Infection Management
Kidney transplantation received substantial attention, reflecting its central role in modern nephrology. For patients with end-stage kidney disease, transplantation remains the best available outcome, but it introduces complex clinical challenges that the program addressed in depth.
Managing BK Virus Infection
The diagnosis and treatment of BK virus infection featured prominently. This viral infection poses particular risk to people with weakened immune systems, especially kidney transplant recipients, in whom it can cause nephropathy and graft loss. Balancing immunosuppression to prevent rejection against the risk of viral reactivation is one of the most delicate judgments in transplant medicine.
Evaluating Donor Risk
The program also examined the risks of transplanting kidneys from donors affected by viral infections, a topic of growing importance as the demand for organs pushes the field to expand acceptable donor criteria. Thoughtful risk assessment can expand the donor pool while protecting recipients.
Pregnancy and Contraception After Transplantation
Sessions covered pregnancy and contraception after kidney transplantation, an area where clinical guidance has evolved considerably. Many transplant recipients can achieve safe pregnancies with proper planning, but timing, medication adjustments, and monitoring all require specialist coordination.
New Approaches to Donor-Recipient Matching and Drug Therapy
Participants learned about new ways of matching donor kidneys with recipients, which can improve graft survival and reduce the need for lifelong high-dose immunosuppression. The program also addressed the use of SGLT2 inhibitors in advanced chronic kidney disease and in patients receiving dialysis, a class of drugs originally developed for diabetes that has reshaped kidney care over the past decade.
For clinicians and researchers following these developments, continuous education is essential. If your work touches on transplantation, nephrology, or internal medicine, consider how attending a focused summer school could sharpen your practice, and follow the latest research news from Semmelweis University to track upcoming events and scientific announcements.
A Milestone Award: Dr. László Rosivall and Excellence in Nephrology Education
The 30th anniversary event carried additional significance with the announcement that its founder and President, Dr. László Rosivall, had been honored with the International Society of Nephrology’s Roscoe R. Robinson Award. Professor Emeritus at the Institute of Clinical Pathophysiology, Dr. Rosivall is a recipient of the Hungarian state Széchenyi Prize and the Iranian KIA Prize, and he will formally receive the Robinson Award, given for excellence in nephrology education, at the World Congress of Nephrology in Kuala Lumpur in April 2027.
His career offers a model of sustained academic contribution:
- He founded both the Hungarian Kidney Foundation and the Budapest Nephrology School, institutions that have educated several generations of nephrologists.
- He has supervised and mentored 32 PhD students during his career.
- His internationally recognized research has focused on renal circulation, the renin–angiotensin system (the hormonal system regulating blood pressure and fluid balance), and renal fibrosis.
- His findings have shed new light on the structure and function of a group of kidney cells that plays a key role in blood pressure and fluid regulation.
For young scientists, Dr. Rosivall’s trajectory demonstrates how deep expertise in a fundamental research area, combined with a commitment to teaching, can produce impact far beyond a single laboratory. Building a research career often starts with the right doctoral training; prospective PhD candidates can review the PhD study options at Semmelweis University to explore mentorship opportunities in pathophysiology and related fields.

Practical Lessons for Aspiring Nephrologists and Researchers
Whether you are a medical student, a resident considering nephrology, or an early-career researcher, the Budapest Nephrology School model offers several actionable lessons:
1. Prioritize Programs That Bridge Research and Clinical Care
The strongest training experiences expose you to both laboratory science and bedside medicine. The 30th BNS program deliberately covered mechanisms of kidney regeneration alongside practical topics like SGLT2 inhibitor use in dialysis patients. When evaluating any postgraduate course, look for this dual orientation.
2. Engage Early with International Networks
Many attendees this year came from countries as diverse as Mozambique, Japan, and Singapore. Networking across borders opens doors to collaborations, fellowships, and perspectives that purely local training cannot provide. Summer schools and congresses are the most accessible entry points, and many, like the Budapest Nephrology School, offer reduced or free registration for local students.
3. Follow the Prevention Agenda
The public lecture in the Grand Hall of the Hungarian Academy of Sciences, open even to high school students, underscored a strategic shift in nephrology: because most chronic kidney disease develops silently over years, prevention and early detection offer the greatest population-level impact. Researchers and clinicians who can communicate this message effectively are increasingly in demand.
4. Choose Institutions with Active Research Communities
The fact that key organizers, including Dr. Orsolya Cseprekál of the Department of Surgery, Transplantation and Gastroenterology and Dr. Nóra Ledó of the Department of Internal Medicine and Oncology, are practicing academics at Semmelweis University illustrates how hosting institutions benefit. Students at such universities gain direct access to visiting experts and cutting-edge topics.

The Broader Case for Kidney Disease Prevention
It is worth stepping back from the academic details to consider why gatherings like this matter for public health. Chronic kidney disease often progresses without symptoms until significant damage has occurred. Risk factors, including hypertension, diabetes, and high salt intake, are widespread. The emphasis the school placed on early detection and on the link between kidney disease and cognitive decline reflects a growing consensus: identifying kidney disease earlier changes outcomes.
For healthcare systems, investing in kidney disease prevention, public education, and professional training pays dividends in reduced dialysis dependence and fewer transplants needed. For individuals, the practical takeaways are straightforward but powerful: manage blood pressure, moderate dietary sodium, stay hydrated, avoid unnecessary nephrotoxic medications, and seek testing if you have diabetes, hypertension, or a family history of kidney disease.
Professor Peti-Peterdi’s public lecture, designed to spark young people’s interest in nephrology and research careers, captured this dual mission: advancing science while raising awareness. Events that open their doors to high school students plant seeds that may grow into the next generation of physician-scientists.
Looking Ahead: The 31st School and Beyond
With three decades of history, backing from the ERA and ISN, and a founder newly recognized with one of nephrology’s most prestigious education awards, the Budapest Nephrology School is positioned to continue shaping the field. The award ceremony at the World Congress of Nephrology in Kuala Lumpur in April 2027 will bring further international attention to Hungarian nephrology and to Semmelweis University’s role in hosting this community.
For readers considering their own involvement, whether as students, researchers, or clinicians, the most useful action is direct: review the program requirements, note the annual timing in late August, and reach out early. Interested applicants and professionals can schedule time to explore Semmelweis University’s educational offerings or contact the relevant departments with questions about future editions of the school and related training pathways.
