Performance of urine samples compared to cervical samples for detection of precancer lesions among HPV-positive women attending colposcopy clinic in Mexico City

This study found strong agreement between self-collected urine samples tested with the INDICAID HPV assay and clinician-collected swabs tested with the BD Onclarity assay for detecting high-risk HPV. The results suggest that urine-based self-collection offers a reliable alternative for cervical cancer screening, potentially improving access for women who face barriers to standard care.

Urine self-sampling for HPV detection showed good agreement with clinician-collected cervical samples (Kappa 0.72) under optimised conditions of 40 mM EDTA preservative, storage at 25°C, and processing within 72 hours. With a cost of USD 1.10 and high acceptability among women and healthcare workers, this method offers a practical decentralised screening approach for resource-limited settings.

In women with HPV, first-void urine collected with the Colli-Pee device had higher HPV DNA concentrations than urine collected with a standard cup, although this advantage disappeared at high HPV DNA loads. Timing of collection (morning versus later) did not affect HPV DNA copies.

This meta-analysis found that HPV testing using self-collected vaginal and urine samples showed sensitivities of 88.6% and 81% for detecting cervical precancer. Using a standardised device for first-void urine increased sensitivity to 86.6%, supporting decentralised patient-centric screening, though data on specificity and specific commercial devices were not consistently reported.

This meta-analysis found that self-collected urine samples for HPV testing had lower sensitivity for detecting high-grade lesions compared to physician-collected cervical specimens. The use of a first-void collection device such as Colli-Pee was associated with marginally higher sensitivity than general urine sampling.
