Source-derived summary

A supernumerary kidney is an additional kidney to the number usually present in an organism. This often develops as the result of splitting of the nephrogenic blastema, or from separate metanephric blastemas into which partially or completely reduplicated ureteral stalks enter to form separate capsulated kidneys; in some cases the separation of the reduplicated organ is incomplete (fused supernumerary kidney).

Less than a hundred cases are known of one or two supernumerary kidneys.

Editorial analysis

Why this record matters

“Supernumerary kidney” is worth following because a concise public description often conceals a longer documentary argument. Here, Supernumerary, kidney and additional provides the most credible route into that argument.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 30, 2024. The linked authority identifier is Q7644074. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2012 and 1590.

Critical limits

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
