ABSTRACT
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.
