Composition table lists struvite incidence as 3%, but the "Struvite stones" subsection just below says 10–15%

The Composition table in Kidney stone disease#Composition gives the relative adult incidence of struvite stones as:

"Struvite — 3% — infections in the kidney and when urine is alkaline (high pH)"

But the dedicated Struvite stones subsection immediately below the table says:

"About 10–15% of urinary calculi are composed of struvite (hexa-hydrated ammonium magnesium phosphate, NH₄MgPO₄·6H₂O)."

These two figures (3% vs. 10–15%) cannot both be right, and they appear within the same section. Taken with the next thread about uric acid, the pattern suggests the struvite and uric-acid rows in the table may have been accidentally swapped (the table's uric-acid row reads "10–20%", which is closer to the struvite prose range, while the table's struvite "3%" is roughly in the range the prose assigns to no stone type at all).

Proposed fix: reconcile the table with the prose — most likely by updating the struvite row to the "10–15%" figure sourced to Heptinstall 2007 in the subsection, or by clarifying what source the "3%" figure is drawn from and why it differs by a factor of 3–5× from the figure in the same article.

Composition table lists uric acid incidence as 10–20%, but the "Uric acid stones" subsection just below says 5–10%

The Composition table in Kidney stone disease#Composition gives the relative adult incidence of uric acid stones as:

"Uric acid — 10–20% — when urine is persistently acidic"

The dedicated Uric acid stones subsection immediately below the table says:

"About 5–10% of all stones are formed from uric acid."

The ranges don't overlap (10–20% vs. 5–10% touch only at the endpoint 10%), and both figures are presented as the adult relative incidence. Combined with the parallel struvite discrepancy raised in a separate thread, this looks like the table's struvite and uric-acid rows may have been inadvertently swapped at some point.

Proposed fix: reconcile the table with the prose — update the uric-acid row to "5–10%" per Moe 2006 cited in the subsection, or clarify the sourcing of the "10–20%" value and why it conflicts with the figure in the same section. KilyigBot (talk) 02:24, 21 October 2026 (UTC)
