Use of transvaginal ultrasound in females with primary bladder neck obstruction. A preliminary study

Abstract

TVUS results worthy in the evaluation of patients with PBNO before and after surgery.

European Association of Urology Guidelines on the Management of Female Non-neurogenic Lower Urinary Tract Symptoms. Part 2: Underactive Bladder, Bladder Outlet Obstruction, and Nocturia

“…The major utility of ultrasound scanning in women with BOO is in detecting possible complications such as bladder wall thickening or upper tract dilatation/hydronephrosis. One study reported that transvaginal ultrasonography was able to demonstrate a closed bladder neck during attempts at micturition and concluded that this modality was useful for the evaluation of possible causal factors in female BOO [38].…”

Diagnostic Tests for Female Bladder Outlet Obstruction: A Systematic Review from the European Association of Urology Non-neurogenic Female LUTS Guidelines Panel

“…The characteristics of the 28 included studies are detailed in Table 1 and Supplementary Table 2. Of these, 25 evaluated the use of UDS AE fluoroscopy [4,[10][11][12][13][14][15][16][17][18][19][20][21][22][26][27][28][29][30][31][32][33][34][35][36], two of which evaluated pre-existing nomograms [35,36], one evaluated the use of transvaginal ultrasound scan (TVUS) and voiding UDS [23], and two looked at transperineal Doppler ultrasound scan (TPUS) [24,25]. Five studies defined cut-offs for UDS parameters [17,26,29,31,32], one study described fluoroscopic characteristics for fBOO [20], one study evaluated the area under the curve (AUC) of detrusor pressure [18], and three studies derived a nomogram to diagnose fBOO [10,14,19].…”

“…Galica et al [23] investigated the role of TVUS in women with LUTS suggestive of BOO, and Q max <12 ml/s and P det.…”

New Frontiers in Molecular and Imaging Research on Evaluation and Diagnosis of Bladder Outlet Obstruction in Women

“…In patients with suspected PBNO on video-urodynamics, transvaginal ultrasound (TVUS) was performed at rest (basal) and during voiding (25). TVUS findings in these patients were characterized by a closed bladder neck during both rest and voiding.…”
