Abstract Background The available literature on urethral length in adult males is limited. To the best of our knowledge, such measurement has never been carried out amongst Nigerian and African men. This study aimed to document average urethral length as well as the relationship between urethral length and age, and anthropometric parameters amongst the Nigerian male adult population to add to the database for urethral length. Methods It was a prospective cross-sectional study amongst adult male Nigerians who had an indication for urethral catheterization as part of their regular treatment at the urologic clinics as well as male adult patients who required urethral catheterization in the theatre and the wards for various reasons. All patients had anthropometric parameters measured or calculated. The total usable length (A) of the catheter was measured before catheterization and the unused catheter length (B) was measured after catheterization for each patient. The calculated urethral length (C) was obtained by subtracting B from A. Data were analyzed using SPSS version 26.0. Mean urethral length was determined while the correlation between urethral length and age as well as anthropometric parameters were determined using Pearson Correlation. Results A total of 450 adult males were recruited. The mean age of subjects was 63.58 years with a range of 22–91 years. The average total usable and unused catheter lengths were 30.01 and 8.97 cm respectively. The mean urethral length among participants was 21.32 cm (8.4 Inches) with a range of 16.5 to 28 cm (6.5–11.0 Inches). There were no statistically significant correlations between urethral length and age ([r (450) = − 0.029, p = 0.546]) as well as with anthropometric parameters (height: r (450) = − 0.088, p = 0.61; weight: [r (450) = − 0.047, p = 0.324 and BMI: r (450) = − 0.082, p = 0.08) in adult males. Conclusion This study suggests that there may be racial differences in adult male urethral length but no relationship with age and anthropometric parameters. Further research is needed to explore these findings.
