Prostatic volume determination by transabdominal ultrasonography: Does accuracy vary significantly with urinary bladder volumes between 50 to 400 mL?

Abstract

Introduction In Ghana, trans‐abdominal ultrasonography is the main sonographic method of prostatic volume evaluation. The examinations are done when the patient's bladder is full. However, the delay and the discomforting experiences associated with a full bladder have been well documented. In an attempt to investigate other less discomforting options, this study was undertaken to determine if sonographic transabdominal prostatic evaluations performed at urinary bladder volumes of 50–99 mL differ significantly to evaluations done at volumes of 100–199, 200–299 and 300–399 mL. Methods A prostatic study of adult patients was undertaken in Accra, from 2014 to 2015. Using an ultrasound machine, 79 sets of prostatic measurements were recorded at a urinary bladder volume of 50–99 mL (V1 as our reference volume), and at least one of three other urinary bladder volumes (V2 = 100–199 mL, V3 = 200–299 mL and V4 = 300–399 mL), in 66 males. Twelve of the participants had multiple sets of prostate volume measurements. SPSS was used to analyse the data. T‐test, Bland‐Altman plots and linear regression were used to compare and test for the existence of proportional biases in measurements. Results There was a statistically significant difference in prostatic volumes recorded at V1 and V2 (P = 0.017). However, the prostatic volume differences recorded for V1/V3, and V1/V4 groups of data were all not statistically significant (P > 0.05). The limits of agreement for the set of measurements spread from approximately −29 to +18 mL for V1/V2, −48 to +36 mL for V1/V3 and −12 to +12 mL for V1/V4 variables. There was no proportional bias in the V1/V2 (P = 0.55) and V1/V4 (P = 0.463) measurements. Conclusion Urinary bladder volume of 50–99 mL produces prostatic volume measurements comparable to volumes measured in patients with a full (300–399 mL), or nearly full urinary bladder (200–299 mL). A urinary bladder volume of 50–99 mL may therefore be adequate for scanning the prostate gland, and is likely to be tolerated much better by patients.

Measurement of Normal Size of Prostatic Gland in Normal Sudanese Men March- October 2019

“…This positive Relationship is expected because aging is a risk for prostate enlargement BPH, and this result agrees with previous studies. (13,14,15) Also, another positive linear relationship between the prostate volume and patient's Weight Table (3), so that an increase in body weight there should be an increase in prostate volume, table (3). This positive relationship is also Expected because an increase in patient weight increases fats concentration in the Body, which was the main source of steroid hormones that influence the growth of the prostate gland.…”

“…Beberapa pemeriksaan telah digunakan dalam mengevaluasi risiko terjadinya BOO termasuk uroflowmetry, intravesical prostatic protrusion (IPP) atau penonjolan prostat intravesika dan volume post void residual (PVR) urine atau residu urin post miksi dan pemeriksaan serum prostate specific antigen (PSA). 11,12 Pemeriksaan ultrasonografi transabdominal dapat mengukur nilai intravesical prostatic protrusion (IPP) dan volume post void residual (PVR) urine. Nilai IPP adalah suatu penonjolan prostat mulai dari leher vesika urinaria ke dalam rongga vesika urinaria yang mengakibatkan mekanisme ball valve di leher vesika urinaria sehingga mengganggu aliran urine yang melewati leher vesika urinaria.…”
