Mid-urethral sling in a day surgery setting: is it possible?

Introduction and hypothesis: Several studies have shown that immediate catheter removal following pelvic surgery is associated with several advantages. The aim of this case–control study is to compare immediate versus delayed catheter removal following mid-urethral sling surgery, to determine if indwelling catheterisation is necessary after this procedure. The secondary outcomes were subjective and objective cure rate after at least a 1-year follow-up. Methods: Cases were defined as all the women who underwent a TVT Abbrevo for urodynamically proven stress incontinence. In every case the Foley catheter was removed by the surgeon at the end of the procedure. A voided volume >200 ml with a post-void residual of <100 ml, was considered a complete voiding trial. Patients who successfully completed the voiding trial and who did not develop any complications were discharged on the day of the surgery. We created a matched control cohort of women who underwent a TVT Abbrevo with delayed catheter removal (24 h after the procedure). Results: Eighty women with immediate catheter removal were included. Each case was individually matched with one control. No statistically significant differences in voiding dysfunctions, postoperative re-catheterisation, postoperative urinary tract infection, early and late onset of overactive bladder (OAB) and vaginal erosion were found between the study groups. No significant differences in either subjective or objective outcome were observed. Conclusions: Immediate catheter removal allows the patient with urodynamically proven stress incontinence without OAB symptoms, prolapse and voiding dysfunctions, to be admitted, treated and discharged on the same day in an outpatient setting, with a high subjective and objective outcomes after at least a 1-year follow-up.
