The aim of this study was to investigate bladder wall thickness (BWT) and ultrasound estimated bladder weight (UEBW) values in healthy population with a portative ultrasound device and their relationship with demographic parameters.
The study was carried out in Neurorehabilitation Clinic of Ege University Hospital. Ninety-five subjects (48 women and 47 men) aged between 18 and 56 were included in the study. BWT and UEBW were determined non-invasively with a portative ultrasound device; Bladder Scan BVM 6500 (Verathon Inc., WA, USA) at a frequency of 3.7 MHz at functional bladder capacity. These values were compared by gender, and their relation was assessed with age, body mass index (BMI) and parity.
Mean BWT was 2.0 ± 0.4 mm and UEBW was 44.6 ± 8.3 g at a mean volume of 338.0 ± 82.1 ml. Although higher results were obtained in men at higher bladder volumes, the results did not differ significantly by gender. Correlation analyses revealed statistically significant correlation between UEBW and age (r = 0.32). BWT was negatively correlated with volume (r = -0.50) and bladder surface area (r = -0.57). Also, statistically significant correlations were observed between UEBW and volume (r = 0.36), bladder surface area (r = 0.48) and BWT (r = 0.25).
Determined values of BWT and UEBW in healthy population are estimated with portative ultrasound devices, which are future promising, for their convenient, easy, non-invasive, time-efficient hand-held use for screening.
本研究旨在使用便携式超声设备调查健康人群的膀胱壁厚度（BWT）和超声估计膀胱重量（UEBW）值，以及它们与人口统计学参数的关系。
本研究在伊兹密尔大学医院神经康复诊所进行。纳入了95名年龄在18至56岁之间的受试者（48名女性和47名男性）。使用便携式超声设备Bladder Scan BVM 6500（美国华盛顿州Verathon公司）在功能性膀胱容量下以3.7 MHz的频率无创测定BWT和UEBW。这些值按性别进行比较，并评估它们与年龄、体重指数（BMI）和生育次数的关系。
平均膀胱容量为338.0±82.1 ml时，平均BWT为2.0±0.4 mm，UEBW为44.6±8.3 g。尽管膀胱容量较高时男性的结果更高，但结果在性别上无显著差异。相关性分析显示UEBW与年龄之间存在统计学显著相关性（r = 0.32）。BWT与容量（r = -0.50）和膀胱表面积（r = -0.57）呈负相关。此外，UEBW与容量（r = 0.36）、膀胱表面积（r = 0.48）和BWT（r = 0.25）之间也存在统计学显著相关性。
健康人群中测定的BWT和UEBW值是使用便携式超声设备估计的，这些设备因其方便、易用、无创、省时的手持式筛查用途而具有广阔前景。
