Surgical Treatment of Female Stress Urinary Incontinence: Do Tapes Stand the Test of Time?

The clinical efficacy and safety of outside-in transobturator sling with additional paraurethral fixation - The prospective longitudinal study

Stress urinary incontinence (SUI) is a common condition that affect 30-40% of women in their lifetime. Midurethral slings (MUS) either suprapubic or transobturator can be safely used in the surgical treatment of SUI. The aim of this study was to collect clinical long-term data regarding safety and performance of transobturator sling with an additional tape fixation in women with urinary incontinence. This prospective longitudinal study was conducted on a group of 2086 female patients diagnosed with stress urinary incontinence. Follow up visits where scheduled 6 weeks, 6 and 12 months after surgery followed by annual checking when possible. Patients underwent transobturator sling procedure from 01.01.2011 to 31.12.2021. All patients had a monofilament tape inserted at the mid-urethra using outside-in technique (TOT) with 2 absorbable sutures parallel to the urethra. Success of surgery was defined as lack of any leakage during cough stress test whereas the subjective cure rate was determined by Incontinence Questionnaire-Urinary Incontinence Short Form (ICIQ-SF). 87% of patients who were operated at least 10 years before assessment reported ICIQ -SF < 6. Main postoperative complications were storage symptoms - de novo urgency and voiding difficulties. TOT is safe and highly effective surgical treatment for (SUI) in a long-term observation.

Impact of radical hysterectomy on the transobturator sling pathway: a retrospective three-dimensional magnetic resonance imaging study

INTRODUCTION AND HYPOTHESIS

Morphological and functional anomalies of the urethra may cause stress urinary incontinence after radical hysterectomy (RH). We introduce a novel three-dimensional (3D) magnetic resonance imaging (MRI) technique to assess the impact of RH on the transobturator sling pathway.

METHODS

3D-MRI reconstruction models were retrospectively developed for the measurement of various parameters before and after RH, including puncture angle, orientation and distance from the midurethral puncture site to the obturator membrane (DUO), in 31 patients with cervical cancer. Additionally, the correlations between DUO and body height and interspinal diameter were evaluated.

RESULTS

No significant differences were noted between the preoperative and postoperative inclination angle (-7.1 ± 33.5° vs. -0.68 ± 23.9°, ranges -62.4 to 46.8° vs. -54.1 to 42.2°, respectively) or between the preoperative and postoperative left and right mean rotation angles (left 69.0 ± 8.0° vs. 67.8 ± 9.2°; right 65.1 ± 8.38° vs. 64.3 ± 10.5°). Similarly, there were no statistically or clinically significant differences between the preoperative and postoperative DUO, although slight differences were noted between the two sides before and after RH (P = 0.018 and P = 0.023, respectively). None of the parameters differed significantly between the groups with and without postoperative urodynamic stress incontinence. Further, there was no clinically significant correlation between DUO and height or interspinal diameter.

CONCLUSIONS

The sling procedure via the transobturator approach is technically safe from a 3D anatomical standpoint. However, wide variability in the anatomical parameters must be taken into account when planning the procedure.
