The usefulness of Toluidine blue dye in the detection of anogenital injuries in sixty females aged 16-40 years of age with a history of consensual sexual intercourse within 48 h of intercourse were included for the study from the Gynaecology outpatient department of the Institute of Medicine, Maharajgunj, Kathmandu, Nepal over a period of 10 months. Injuries were identified and documented using TEARS classification (tears-ecchymosis-abrasion-redness-swelling) before and after the application of toluidine blue dye (TBD). Anogenital injuries were detected in 6.7% participants (4 out of 60) before the dye application and 20% participants (12 out of 60) after the dye application. Thus, TBD application increased the detection of anogenital injuries three times compared to that of the naked-eye examination. Applying the Chi-square test, there were significant differences in the detection of tears and abrasions after TBD application (p-value - 0.035 and 0.042 respectively).
