Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Women with symptoms of voiding dysfunction may be associated with detrusor underactivity (DU) or bladder outlet obstruction (BOO). The treatment strategies are different between DU and BOO. In general, urodynamic/videourodynamic studies are important for differential diagnosis. However, urodynamic/videourodynamic studies are invasive. The investigators are interested in whether there were specific symptoms or measurements that can be used for initial differential diagnosis between DU and BOO. Thus, the aim of this study was to elucidate the prevalence of DU and BOO in each age group and elucidate the clinical and urodynamic differences between the DU, BOO and non-DU/BOO groups.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Between April 1996 and September 2018, all women with symptoms of voiding dysfunction who visited the urogynecological department of a medical center for urodynamic evaluation were reviewed. Those women who have no complete data of maximum flow rate (Qmax), voided volume, post-void residual volume (PVR) and detrusor pressure at a maximum flow rate (PdetQmax) were excluded from this study. Besides, women with cystocele were also excluded. The DU was defined when the PdetQmax was less than 20 cmH2O, the Qmax was less than 15 mL/s, and the bladder voiding efficiency (BVE) was less than 90 %. The BOO was defined when the PdetQmax was not less than 40 cmH2O, and the Qmax was less than 12 mL/s. BVE = voided volume / (voided volume+ PVR) x 100%. Those women without DU or BOO were allocated to the non-DU/BOO group.

STATA software was used for statistical analysis. ANOVA test with Bonferroni correction or chi-square test was used for statistical analysis as appropriate. Linear regression analysis with age adjustment was used to assess the adjusted effect of variables. P \< 0.05 was considered as statistical significant.

Detrusor underactivity

The DU was defined when the PdetQmax was less than 20 cmH2O, the Qmax was less than 15 mL/s, and the bladder voiding efficiency (BVE) was less than 90 %. BVE = voided volume / (voided volume+ PVR) x 100%.

Urodynamic study

Intervention Type DIAGNOSTIC_TEST

The urodynamic assessment included uroflowmetry, filling cystometry with 35°C distilled water at a rate of 60 mL/sec, a pressure flow study, and a stress urethral pressure profile with patient in sitting position \[14\]. A 20-minute pad test for each woman was also performed \[15, 16\]. Multichannel urodynamic equipment (Life-Tech, Houston, TX, USA) with computer analysis and Urovision (Urolab Janus System V, Houston) was used. All terminology conformed to the standards recommended by the ICS \[3\]. All procedures were performed by an experienced technician, and the data were interpreted by a single observer to avoid interobserver variability.
