eChapters

Textbook-length, fully cited clinical chapters on the topics nephrologists actually teach and refer to — peritoneal dialysis, AKI-to-CKD, kidney fibrosis, transplant recurrence, uraemic toxins. Web-native, updated as the evidence moves.

Why this exists

Half the world lacks any access to kidney care, and the other half spends a decade behind the evidence.

NephroZayan is an open commons — no logins, no paywalls, no advertising. The site is built and maintained by working nephrologists who write what they wish they had at 3 a.m. on call. If a calculator, guideline summary, or patient handout earns its place at the bedside, it stays. If it doesn't, it goes.

Every page tells you what it cites, who reviewed it, and when.

Editorial integrity is not a section in a footer — it is the architecture of the site. Every calculator carries its source equation. Every guideline page lists its KDIGO or ISPD chapter, last review date, and named clinician reviewer. Conflicts of interest are disclosed. AI-assisted drafting is declared per ICMJE 2025 standards.
