Abstract: Background: Human papillomavirus (HPV) is a key factor in cervical cancer development. This study aimed to compare the efficacy of urine and cervical samples for HPV genotyping, evaluating their diagnostic performance in detecting high-risk HPV genotypes. Methods: This comparative cross-sectional study conducted over one year at the Department of Gynaecological Oncology, BSMMU, Dhaka, the study enrolled 74 women aged 30-60 years with positive visual inspection with acetic acid (VIA) results or abnormal Pap test findings. Urine samples (20 ml) and cervical samples were collected from each participant. The samples were analyzed using multiplex real-time PCR to amplify high-risk HPV types (16, 18, and others). DNA was extracted using the Qiagen viral DNA extraction kit. Sensitivity and specificity of HPV detection in urine samples were compared to cervical sampling, the gold standard. Data were analyzed with SPSS 22.0, and agreement was assessed using the Kappa index. Result: Cervical samples detected HPV in 17.56% of participants, while urine samples identified HPV in 5.40%. The agreement between urine and cervical samples was moderate, with a kappa value of 0.743. Among 74 cases, 5 cases were detected as HPV 16 and HR (co-injection) in both cervical and urine sample, 2 cases as HPV 16 in both cervical and urine samples, 2 cases as only HR type in both cervical and urine sample. The kendall’s correlation of agreement was 0.361 and a significance of 0.002. Conclusion: Cervical samples are more reliable for HPV detection compared to urine samples, though urine testing shows high sensitivity.
