Introduction: The aim of the study was to analyse the correlation of subjective complaints and urethral pressure profilometry (UPP) data in women with different types of urinary incontinence (UI): stress UI (SUI), urgency UI (UUI), and mixed UI (MixUI). Methods: A study group of 405 women with complaints about UI were surveyed (UDI-6; ICIQ-UI) to determine the subjectively dominant type of UI, and UPP was performed for all these women. The variables analysed by UPP were the maximum urethral closure pressure at rest (MUCPrest), maximum urethral closure pressure at cough stress (MUCPstress), functional urethral length at rest (FULrest), functional urethral length during cough stress (FULstress) test and pressure transmission ratio (PTR). The statistical variation between different groups of UI patients was calculated for all the analysed variables. Results: The value of PTR was statistically and significantly higher in the group of patients with isolated UUI, compared to the SUI and MixUI groups. The MUCPrest and MUCPstress values were consistently lower in women with isolated SUI, compared to isolated UUI. The FULrest and FULstress values showed no statistically significant difference between the groups with different types of UI. Conclusions: The PTR value is a result of UPP test that helps in distinguishing objectively between UUI, SUI, and MixUI. The PTR value can be used to characterise the hypermobility of urethra. The MUCPrest and MUCPstress values are consistently lower in women with isolated SUI, compared to those with isolated UUI. MUCP can be used as an objective criterion for differentiation of these 2 groups of patients.
Introduction
The aim of this study was to find out if there are any conventional urodynamic (UDS) variables that would help to predict the necessity of overactive bladder (OAB) symptomatic therapy in women after transobturator tape surgery (TOT).
Material and methods
A total of 487 females after TOT were enrolled in this retrospective study. Inclusion criteria (UDS before surgery, follow-up visit within 2–6 month after TOT) were met in 169 women. Based on patient history, questionnaires and physical examination, two groups were distinguished: pure stress urinary incontinence (SUI) and stress-predominant mixed urinary incontinence (MixUI). A statistical analysis was performed including age and UDS variables. T-test was used for continuous data and Chi-squared test for categorical data. Combinations of these factors were analyzed using binary logistic regression and surgery outcome as the target variable.
Results
Significant correlations between the probability of a need for OAB therapy after TOT were observed with age (higher age increases OAB therapy necessity, p <0.001) and such UDS variables as cystometric capacity (CC) p <0.001; maximum flow rate (Qmax) p <0.001; detrusor contractility index (DCI) p <0.015 – higher value decreased the need for OAB therapy. Critical limit for these values: 60 years for age, 300 ml for CC, 15 ml/s for Qmax, but no specific value for DCI was observed. Binary logistic regression showed that the UI Group (p <0.01) and CC (p = 0.01) allow correctly classify 78.9% of TOT outcome (increased CC and SUI group are factors for TOT normal outcome).
Conclusions
UI group, age, CC, Qmax, DCI can help to predict the necessity of OAB symptomatic therapy in women after TOT.
