Loop surgery in women with urinary incontinence and urodynamics of the lower urinary tract

Abstract

Objective: The aim of the study is to objectify and evaluate urodynamic changes in women having urinary incontinence before and after performing synthetic sling operations.Methods: During the period from 2002 to 2020 104 women were observed (average age 54 years) who underwent trocar synthetic sling surgery. The group under observation included patients with a combined form of incontinence. The main method of urodynamic diagnosis was non-invasive 2-day uroflowmonitoring.Results: When comparing the data before and after TSS operation the following changes were found: an increase in the minimum capacity and a decrease in the maximum released volume, but together with this, the change in the average effective volume was unreliable. At the same time the structure of urination has radically changed. The indicators of the average value of the maximum flow have decreased and the entire speed profile has changed in general.Conclusions: Uroflowmetric monitoring makes it possible to identify objectively, adequately and non-invasively the urodynamic disorders in patients with urinary incontinence, which occur both in the preoperative and postoperative periods. According to the neurophysiological model these changes can be explained by the influence of the implant on micturition reflexes.
