Sensitivity of Urinalysis in Detecting Nephrolithiasis

  • The sensitivity of urinalysis in detecting nephrolithiasis is not directly stated in the provided studies, but we can look at the sensitivity of related tests.
  • A study from 2008 1 found that the sensitivity of 24-hour urine calcium for detecting elevated calcium oxalate supersaturation was 71% in men and 79% in women.
  • The same study found that the sensitivity of 24-hour urine oxalate for detecting elevated calcium oxalate supersaturation was 59% in men and 36% in women.
  • Another study from 2021 2 mentions that urine tests, including hematuria and crystalluria, are important supplementary diagnostics for detecting kidney stones, but does not provide specific sensitivity values.
  • A study from 1988 3 found that the sensitivity of ultrasonography for detecting renal calculi was 96%, but this is not directly related to urinalysis.

Related Tests and Sensitivity

  • The sensitivity of 24-hour urine analysis for detecting elevated calcium oxalate and calcium phosphate supersaturation is reported in the 2008 study 1.
  • The study from 2020 4 discusses the opportunities and challenges of utilizing urinary biomarkers for kidney stone prevention, but does not provide specific sensitivity values for urinalysis.
  • The study from 2023 5 provides an overview of urinalysis, but does not discuss the sensitivity of urinalysis in detecting nephrolithiasis.
  • The study from 2008 1 suggests that traditional 24-hour urine analysis is sensitive, but not specific, for detecting elevated calcium oxalate and calcium phosphate supersaturation.
