Is There any Association between Urothelial Carcinoma of the Bladder and Human Papillomavirus? A Case-Control Study
Sarier et al.
The finding, in our words
HPV DNA was detected significantly more often in first-void urine from patients with urothelial carcinoma than from controls, indicating an association between HPV infection and bladder cancer.

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.

DNA methylation markers in first-void urine effectively detect high-grade cervical lesions in HPV-positive women, with results similar to clinician-collected samples in those over 30. This enables reliable cervical cancer screening using self-collected urine, reducing the need for invasive follow-up procedures in decentralised settings.
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.
A comparison of human papillomavirus detection in first-void urine and cervicovaginal samples from Colombian women showed moderate prevalence but weak concordance between the two methods. Although urine-based screening offers a non-invasive alternative, its limited diagnostic performance in this study highlights the ongoing need to optimise collection and processing strategies for decentralised screening.
