A modified Altis ® mid-urethral sling that allows immediate post-operative adjustment: experience in 197 patients
International urology and nephrology
Objectives: The transobturator mid-urethral Altis® "mini-sling" uses a static and a dynamic anchor on either end of a pulley suture for intraoperative tension adjustment. Given the potential for incorrect tensioning with sling placement, we adopted a modification for post-operative adjustment should stress urinary incontinence (SUI) persist. The objective is to describe technique, rate of postoperative adjustment driven by patient symptoms, and impact of preoperative/intraoperative variables.
Methods: In this single-surgeon experience, retrospective chart review, demographic and clinical data were collected on patients who received the Altis® sling for SUI between 2014 and 2019. We used descriptive statistics and three-group comparison tests to assess difference in variables among tightening, loosening, or no adjustment.
Results: Altis® sling placement was performed on 197 female patients with an average age of 58.7 years. Eighty-four percent (165/197) did not receive post-operative adjustment. Of the 32 patients with post-operative adjustment, 8 (4.1%) had loosening and 24 (12.2%) had tightening at an average of 10.5 days post-operatively. All tightening procedures were done in the clinic. Of the 8 patients with post-operative loosening, 6 were performed in clinic and 2 in the operating room. Preoperative and intraoperative variables were not significantly different among tightening, loosening, and no adjustment cohorts.
Conclusions: This modification of the Altis® sling provides surgeons with the ability to tighten and loosen the sling for persistent SUI. All tightening and most loosening procedures were able to be performed in the clinic. The ability to easily tighten a sling in the early post-operative period may be a critical advantage.
