Renal & Nephrology Abbreviations
This list collects 413 renal & nephrology abbreviations — kidney, dialysis and transplant terms used in nephrology notes and renal unit charts. Every entry shows the full form and a plain-English meaning. One abbreviation can appear in several specialty lists when it is genuinely used in more than one area, and abbreviations with more than one common meaning get a row for each meaning. Terms flagged ⚠ Error-prone are on recognised error-prone lists: write them out in full wherever possible.
The printable sheet carries this page's web address and a QR code, so a paper copy always leads back to the live searchable list at https://www.medicalvideos.com/medical-abbreviations/renal/
