The role of conventional urodynamic in diagnosing specific types of urinary incontinence in women

Objective:  To analyze the association between patient history profile, conventional urodynamic variables, and specific types of urinary incontinence (UI) in order to establish the role of urodynamic in differentiating various types of UI in women.

Material and methods: This cross-sectional study enrolled 547 women with UI. All patients were divided into three groups according to the UI type based on questionnaires: stress UI (SUI), mixed UI (MixUI), and urgent UI (UUI). Patient history taking, physical examination, and conventional urodynamics were performed. The association between patient profile characteristics, urodynamic data, and type of UI were assessed using one-way analysis of variance and chi-square tests.

Results: Significant correlations were observed between the age, body mass index (BMI), cystocele, menopausal status, and most urodynamic data in at least one UI group (p<0.05). Age differed among all three groups (p<0.001), with SUI group consisting the youngest patients. BMI was higher in the MixUI group (p=0.001). The maximum cystometric capacity differed among all three groups (p<0.001), with the highest in the SUI. The maximum flow rate was higher in the SUI group than that in the UUI group (p<0.001). Residual urine, opening detrusor pressure, and pressure transmission ratio were significantly higher in the UUI group. Detrusor overactivity and menopause were less frequently observed in the SUI group. The least pronounced urodynamic SUI was found in the UUI group. Spearman correlation for cystocele was negative in the SUI and positive in the UUI group.

Conclusion: Conventional urodynamics give additional information to correctly diagnose specific types of UI in women.
