Abstract

Purpose: This study aimed to investigate the effects of preoperative Valsalva leak point pressure (VLPP) on the outcomes of the single-incision midurethral sling procedure (Needleless® System) in female stress urinary incon­tinence (SUI).

Materials and Methods: We evaluated 112 patients who underwent midurethral sling placement for SUI using the Needleless® System. Patients were divided into two groups according to their preoperative VLPP values: VLPP >90 cmH2O (group 1) and VLPP 60-90 cmH2O (group 2). After the postoperative period, SUI status and satisfac­tion were compared between the two groups. Subjective cure was defined as the absence of any episodes of urinary incontinence associated with conditions that increase intra-abdominal pressure in daily life. Treatment satisfaction was analyzed according to patient responses as 'satisfied', 'neutral', and 'dissatisfied'. Postoperative other lower urinary tract symptoms except SUI were compared between the two groups too.

Results: There were no significant differences in age, body weight, and urodynamic parameters (except VLPP) between the two groups. The mean VLPPs were 105.9 ± 12.3 cmH2O (range, 93.6¬-118.2 cmH2O) in group 1 and 75.4 ± 10.5 cmH2O (range, 65-85.9 cmH2O) in group 2. The overall subjective cure rates were 65.0% in group 1 and 62.5% in group 2 (P = .744). The overall satisfaction rates were 58.8% in group 1 and 68.8% in group 2 (P = .600). Complication rates did not differ between the two groups.

Conclusion: When stratified as > 90 cmH2O or ≤ 90 cmH2O, preoperative VLPP did not affect Needleless® Sys­tem outcomes in female SUI patients.
