Figure 1a. (a) Longitudinal US images of the bladder show relaxed detrusor (left) and contracted detrusor (right). Simultaneous alteration of the shape of the bladder and the appearance of the bladder wall took place, with an increase in the anteroposterior diameter, a decrease in the longitudinal diameter, and a serrated appearance of the wall (arrow). (b) Transverse US images of the bladder show contracted detrusor (left) and relaxed detrusor (right). The bladder changed in shape from quadrangular to rounded, and the wall appears serrated (arrows).

Figure 3. Longitudinal US images of the bladder. Arrow shows the position of the bladder neck. Left image shows cephalic position of the bladder neck during the contraction of the pelvic floor muscle. Right image shows caudal position of the bladder neck when the pelvic floor muscle is relaxed.

Figure 4a. Images show alterations that indicate increased bladder pressure. All images were obtained during the same examination. (a) Longitudinal images of the left kidney show a dilated collecting system (arrow). (b) Bladder features small diverticula. During dynamic US, it is possible to observe the difficulty of emptying the ureter. Arrow indicates the left ureter. (c) Immediately after voiding of the bladder, the collecting system of the kidney is almost empty (arrow).
