34th European Congress of Pathology 2022 in Basel

Amélie presented the preliminary version of the coding system as a poster: “A multihierarchical terminology for non-neoplastic kidney biopsies: Kidney biopsy codes for pathologists”.

European Congress of Digital and Integrative Pathology ECDP 2022

KBC participated at the European Congress of Digital Pathology ECDP 2022 in Berlin!
Sabine told the story how we developed our coding system for non-neoplastic kidney biopsies and what we can learn from this for developing terminologies in general. We also showed one of Hrafn’s nice visualizations of the coding system.

Amélie has presented our poster at WCN 2022 Kuala Lumpur, Malaysia, 24th February:

Mapping kidney biopsy codes to SNOMED CT

Systematic reporting of medical kidney biopsies –

Thinking about international standardization of the pathology report – both the information model and coding system behind the report:

CKJ review

Our first paper is out – 24th Mai 2021!

The results from WP1 have just been published in BMC Nephrology – thanks to all stakeholders and participants, not in the least all the registries!

On Thursday 22nd April we got the opportunity to present the project on the SNOMED CT business meeting – clinical session.

Fit for SNOMED CT ? – Kidney Biopsy Codes for Pathologists

Thank you for the opportunity to connect!

Project meeting in Antwerpen 21th February 2020

A brainstorming Friday evening in Antwerpen: We looked together at the draft of the code list, discussed how to use the list and made plans for a review process.

Work package 3 Workshop – discussing the first draft of the coding list

During the 31th European Congress of Pathology in Nice, on Monday 9th September 2019, the KBC WP3 team has held a Coding Workshop.

In this workshop, a first draft of the term list was discussed, and participants had the opportunity to comment on the proposition. Sabine and Amélie are now busy processing the comments and revising the draft. We will keep you updated!

Poster presentation at the ERA-EDTA Congress in Budapest 14th June 2019

Amélie presented an update of the project in Budapest at the ERA-EDTA congress:

Kidney Biopsy Codes for Pathologists: an update

We developed the basic structure of the code list. There will be an axis for morphological patterns and an axis for disease concepts.
To keep the list manageable, we formed groups of codes according to the kidney compartments.
A certainty factor can be added. There will most probable be three different levels of certainty: confirmed – probable – suspected.
We are now working intensively with the list and try to cover every morphological pattern and disease concept. However,  for people who would rather have a short code list, there will be a compact version too :).

Renal Pathology Society (RPS) webinar 15th March 2019: Harmonization of renal biopsy coding 

The new 2019 board of the RPS invited us to form a working group under the RPS scientific committee, in order to incorporate stakeholder input from registry people all over the world into the project and give and receive feedback from other RPS initiatives. This Harmonized Coding Working Group is now getting assembled. As a first event, a webinar was organized the 15th of March 2019 by RPS and conducted by Sabine and Amélie.  RPS webinar

The central project team’s workshop in Amsterdam (The Netherlands) 16 – 18 November 2018

It was planned for a long time and finally the central project team (Amélie and Sabine) met for a coding weekend in Amsterdam.  We had a pile of kidney biopsy reports ahead of us and term lists prepared by Mark. On Sunday 40 reports had been  tentatively coded, term lists modified and not yet solved coding problems written down. Using real reports was extremely helpful – thanks to all contributers!

Poster presentation at Kidney Week 2018, San Diego (USA), 23 – 28 October 2018

Amélie at ASN 2018Amélie presented the results from work package 1 at the Kidney Week as a poster:

“Beyond Morse: How Do Kidney Biopsy Registries Code Renal Disease? On Behalf of the Kidney Biopsy Codes (KBC) for Pathologists Project”

Thanks to all kidney biopsy registries that have contributed with information about current coding systems, problems related to their systems and needs for future solutions!

Presentation at 30th European Congress of Pathology, Bilbao (Spain), 8 – 12 September 2018


The project was shortly presented in the Business meeting of the Nephropathology Working Group on Sunday and then in the oral free paper joint session Pulmonary Pathology / Nephropathology:

“Kidney biopsy codes for pathologists: towards a generally applicable terminology and coding system”
