On TPUS, the behaviour of the bladder neck and proximal urethra was described by the urethral length, urethral funnelling, bladder neck descent (BND), retrovesical angle (RVA) and urethral rotation angle (URA).

On TPUS, urine leakage was detected in the supine or standing position in 102 women and in both positions in 81. Between the two positions, significant differences were found in the URA and RVA.
