<p class="Abstract">This study was performed to standardize the ultrasound estimated bladder weight as an additional non-invasive test for the measurement of the bladder outflow obstruction and to measure the therapeutic effects of bladder outflow obstruction in the follow-up after surgical correction of obstruction. This study was conducted from December 2012 to May 2014 where the sample size was 55 and sampling technique was purposive. In bladder outflow obstruction patient, transabdominal sonography was performed using a 7.5 MHz. probe. The anterior bladder wall thickness was measured in three points in the midline 1 cm apart and the average value was recorded. After that bladder volume was measured by ultrasonogram. In pre- and post-operative groups ultrasound estimated bladder weight was measured from bladder wall thickness and bladder volume. In this study, the mean ± SD of age was 48.8 ± 15.0 years. In bladder outflow obstruction patient, the pre-operative ultrasound estimated bladder weight was 117 ± 45.1 g which was reduced to 53.9 ± 10.8 g three months after surgical correction of obstruction. The ultrasound estimated bladder weight is a non-invasive, cheap and easily available additional diagnostic tool for detecting bladder outflow obstruction as well as it can measure the therapeutic effects in post-operative period.</p>

Aim: The present study was undertaken with the aim to standardize ultrasound measured urinary bladder wall thickness (UMUBWT) as an additional routine noninvasive test to assess the bladder outflow obstruction (BOO) and to monitor the therapeutic effects of BOO in follow-up after surgical correction of obstruction. Methods: This is an interventional study (pretest-posttest type of clinical trial) conducted between December 2012 to May 2015 where sample size was 55 and sampling technique was purposive. In BOO patient transabdominal sonography was performed using a 7.5 MHz. probe. The thickness of the anterior bladder wall at the midline was measured in both preoperative and postoperative period ( three months after operation) at 3 points approximately 1 cm apart and the average value was recorded. Results: In this study age range was 21-73 years with mean±SD of age was 48.76±15.08 years. In BOO patient preoperative UMUBWT was 0.51 ± 0.16 cm and which reduced to 0.26 ± 0.05 cm three months after surgical correction of obstruction. Conclusion: UMUBWT is a noninvasive, cheap and easily available additional diagnostic tool for detecting BOO as well as it can measure the therapeutic effects in postoperative period.

Background: Liver cirrhosis represent the end stage of fibrosis that destroy normal liver parenchyma and leads to serious complication as portal hypertension which result in esophageal varices (EV), EV bleeding leads to high mortality, so repeated upper endoscopy needed to control bleeding which is invasive procedure and of high risk of hazards as infection. Our Study Aimed: to evaluate the Gallbladder Wall Thickening (GBWT) as a non-invasive predictor of Esophageal Varices (EV) in cirrhotic patients. Methods: In this cross sectional study, we tested 120 cirrhotic patients at gastroenterology and hepatology unit, internal medicine department, Tanta university hospitals. They were divided into 60 cirrhotic patients with EV and 60 cirrhotic patients without EV. All patients were subjected to history taking,  physical examination, investigation (complete blood count, liver function tests, viral markers) ultrasound detecting (gall bladder wall thickness, portal vein diameter, portal vein flow velocity, portal cross sectional area and gall bladder fasting volume) upper gastrointestinal endoscopy to detect presence or absence of varices. Results: Significant correlation was observed between gall bladder wall thickness (GBWT) and portal hypertension, GBWT ranged from 2.5 to 7 mm in group 2 (cirrhotic patients with EV) and from 1.5 to 5 in group 1( cirrhotic patients without EV). There is significant difference between group 1 and group 2 as regard GBWT with (P value < 0.05), portal vein diameter (PVD) with (P value <0.05) and platelets counts with (P value <0.05). Conclusions: We recommend thatgall bladder wall thickness can be used as a non-invasive predictor of esophageal varices in cirrhotic patients.

Abstract Background Methods for the non-invasive quantification of changes in bladder wall thickness as potential predictors of radiation cystitis in pre-clinical research would be desirable. The use of ultrasound for this aim seems promising, but is still relatively unexplored. A method using ultrasound for bladder wall thickness quantification in rats was developed and applied to measure early radiation-induced bladder wall thickness changes. Methods Two groups (n = 9 each) of female Fischer rats were treated with a single radiation dose of 25–30 and 35–40 Gy respectively, using an image-guided micro-irradiator; six untreated rats were monitored as a control group. Empty, half-filled and fully-filled bladder volumes were determined for four non-irradiated rats by measuring axes from ultrasound 3D-images and applying the ellipsoid formula. Mean bladder wall thickness was estimated for both ventral and dorsal bladder sides through the measurement of the bladder wall area along a segment of 4 mm in the central sagittal scan, in order to minimize operator-dependence on the measurement position. Ultrasound acquisitions of all fully-filled rat bladders were also acquired immediately before, and 4 and 28 days after irradiation. Mean bladder wall thickness normalized to the baseline value and corrected for filling were then used to evaluate acute bladder wall thickening and to quantify the dose–effect. Results The relationship between mean bladder wall thickness and volume in unirradiated rats showed that for a bladder volume > 1.5 mL the bladder wall thickness is almost constant and equal to 0.30 mm with variations within ± 15%. The average ratios between post and pre irradiation showed a dose–effect relationship. Bladder wall thickening was observed for the 25–30 Gy and 35–40 Gy groups in 2/9 (22%) and 5/9 (56%) cases at day 4 and in 4/9 (44%) and 8/9 (89%) cases at day 28, respectively. The two groups showed significantly different bladder wall thickness both relative to the control group (p < 0.0001) and between them (p = 0.022). The bladder wall thickness increment was on average 1.32 ± 0.41, and was 1.30 ± 0.21 after 25–30 Gy and 1.47 ± 0.29 and 1.90 ± 0.83 after 35–40 Gy at days 4 and 28 respectively. Conclusions The feasibility of using ultrasound on a preclinical rat model to detect bladder wall thickness changes after bladder irradiation was demonstrated, and a clear dose–effect relationship was quantified. Although preliminary, these results are promising in addressing the potential role of this non-invasive approach in quantifying radiation cystitis.

The aim was to establish reference values of bladder wall thickness (BWT), detrusor wall thickness (DWT), and bladder weight (BW) in apparently healthy adults in a Nigerian population. Therefore, a cross-sectional study of healthy adult participants was conducted from May 2015 to April 2016. The urinary bladder was sonographically evaluated on a convenient sample of 384 adult participants. The BWT, DWT, and BW of the participants were measured and documented. The BW was estimated based on the surface area, thickness, and bladder muscle specific gravity. The mean BWT, DWT, and BW were 2.8 ± 0.3 mm, 1.3 ± 0.1 mm, and 23.3 ± 4.1 g, respectively. There was no statistically significant correlation between anthropometric variables with BWT, DWT, and BW except age, which had a weak positive correlation with BWT ( P = .05). This data set could be used for future research, in other parts of the country, for a possible nationwide nomogram.
