A standard full bladder volume of 300-400ml (BV300-400) was used as the standard reference. MATERIALS & METHODS 36 male volunteers aged 30 years old and above were scanned at different bladder volumes: BV50-99, BV100-200, and BV300-400. The prostate volumes were measured by a sonographer using an ultrasound scanner (GE Logiq V5) with a convex transducer of 3.0-5.0 MHz. Meanwhile, the image quality assessment was performed by a radiologist. The evaluations were based on three criteria; the visibility of the prostate walls, the transitional lobe, and the symmetrical of the prostate. RESULTS Bland Altman plot evidenced that BV50-99 tended to overpredict prostate volume by 0.71ml, and BV100-200 underpredict by 0.53ml. BV50-99 revealed a narrower 95% CI limit of agreement (0.71±7.03 ml) compared with BV100-200 (-0.53±10.74). Meanwhile, Chi-square showed that BV100-200 was better to demonstrate all the image quality criteria than BV50-99 (prostate walls visibility: 100% vs 97%, transitional lobe visibility: 56% vs 47%, and prostate symmetry: 100% vs 97%). However, Chi-square reported low visibility on the transitional zone regardless of the bladder volumes. CONCLUSION BV50-99 was suggested for prostate volume estimation. For cases that require the assessment of the prostate morphology such as the margin, parenchyma, and prostate symmetry, BV100-200 was the most preferable. However, the TAUS examination was not recommended to assess any pathology involving the prostate's transitional lobe.
