Description
Objective: To determine the accuracy of various ultrasound formulas for measuring the testicular volume in humans by comparing the resultant measurements with the actual testicular volume. Subjects and methods: The testicular volume of 121 testes from 62 patients with prostate cancer (mean age 72.7±9.4) was measured using ultrasonography before therapeutic bilateral orchidectomy. The ultrasound measurements of the testicular volume were calculated using the following three formulas: (a) length (L)×width (W)×height (H)×0.52; (b) L×W2×0.52 and (c) L×W×H×0.71. The actual testicular volume was determined by water displacement of the testis. Results: The mean actual testicular volume was 10.6. ±. 3.5. ml. A strong correlation was found between the actual testicular volume and the volume calculated by the three-ultrasound formulas (. r=. 0.853-0.871, p=. 0.0001). The smallest mean difference from the actual testicular volume was observed with the formula L×. W×. H×. 0.71, which underestimated the actual volume by 0.4. ml (3.9%). Conclusion: The results of this study show that ultrasonography and the formula L×. W×. H×. 0.71 are the most accurate method for the calculation of the testicular volume. © 2013 Pan African Urological Surgeons' Association.
