Human papillomavirus self-sampling and urine-sampling tests and the management and short-term outcomes of cervical intraepithelial neoplasia: A prospective observational study
Matsuura et al.
The finding, in our words
Among 105 women with grade 1 cervical intraepithelial neoplasia followed for a median 20 months, 29.3% experienced disease progression or persistence, which was significantly predicted by HPV positivity in physician- and self-collected samples. In 59 women with grade 2 disease followed for a median 12 months, half showed progression or persistence, but HPV status from physician-, self-, or urine-collected samples did not predict outcomes. Self-collection may enable decentralised risk stratification for CIN 1 surveillance.

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.

A study of 2500 women found 99.0% agreement between first-void urine and vaginal self-sampling for HPV detection using Cobas4800, with 98.1% of participants preferring urine. Although conducted in a resource-limited setting which may limit generalisability, these results support urine as a viable sample type for decentralised, patient-centric screening.
This study found that self-collected vaginal swabs and first-void urine yielded comparable detection rates for vaccine-targeted high-risk HPV types, supporting the use of both patient-centric methods for decentralised surveillance. Vaginal swabs showed higher sensitivity for non-vaccine types, whereas urine sampling offers a non-invasive alternative.
First-void urine and self-collected vaginal swabs showed similar sensitivity and specificity to clinician-collected cervical samples for high-risk HPV detection across two real-time PCR assays, supporting their use as decentralised, patient-collected alternatives; most women preferred first-void urine for regular cervical screening.

First-void urine samples showed significantly higher detection rates of HPV-specific IgG antibodies compared to midstream urine, confirming the necessity of capturing the initial stream. The study found no significant difference between 10 mL and 20 mL collection volumes, indicating flexibility in device specifications for self-collection.
