Experience in application of modified sling in treatment of Moderate Stress Urinary Incontinence

Abstract

Objective: To observe the clinical significance of modified sling in the treatment of moderate stress urinary incontinence (SUI). Methods: From January 2016 to January 2019, eighty patients with moderate urinary incontinence who were hospitalized in our hospital were randomly divided into two groups. 40 patients in the experimental group underwent modified sling transvaginal tension-free mid-urethral suspension. Modification method of the sling: cut the sling to a remaining length of about 6~7cm, properly connect the barbed sutures (V-LOCK) on both sides of the sling, and insert the urinary incontinence sling from the urethra to the obturator membrane, from the obturator membrane to the thigh. The inner skin area is replaced by the V-LOCK line. The 40 patients in the control group were unmodified ordinary slings. The operation time, the local pain of the inner thigh after the operation, and the improvement of postoperative urinary incontinence symptoms were compared and analyzed between the two groups. Results: Both groups of patients were successfully operated. The operation time was 16.36 minutes in the experimental group and 27.18 minutes in the control group. The difference in operation time between the two groups was statistically significant (p=0.00); the catheter was pulled out on the third day after the operation. One patient in the group had urinary effort, four patients still had urinary incontinence symptoms, the remaining 35 patients had good urinary control (effective rate 87.5%), five patients in the control group still had urinary incontinence, two patients had urinary effort, and the remaining 33 patients had urinary control Good, (effective rate 87.5%), there was no significant difference in surgical effectiveness between the two groups (p=0.53); follow-up for 12 to 36 months, no significant long-term complications occurred, the pain score of the inner thigh of the experimental group was significantly lower than that of the control group ,statistically significant (p=0.04). Conclusion: The efficacy of the modified sling in the treatment of moderate SUI is the same as that of the traditional sling, but the operation time is shorter, the operation is simpler, and the local pain is significantly reduced. doi: https://doi.org/10.12669/pjms.36.7.2619 How to cite this:Guo J, An F, Gu D, Yang W.
