Dear Editor,

We are grateful to van der Weiden and Withagen for sharing their findings [1].

We observed an overall de novo SUI rate of almost 30 % among our cohort of open and minimally invasive sacrocolpopexy (SCP) patients with negative preoperative prolapse reduction stress testing (PRST) [2]. In our statistical model, we noted a clear specific relationship between de novo stress urinary incontinence (SUI) and Aa reduction magnitude, regardless of surgical route. Patients with a high (6 cm ≥ ∆Aa < 4 cm) Aa reduction magnitude were at the highest risk. These findings warrant careful attention to anterior reduction during PRST. False-negative testing may reflect a mismatch between instrumented Aa reduction at PRST and surgical Aa reduction at SCP. Effort should be made to closely match reduction at testing with anticipated surgical reduction, especially when the expected Aa reduction magnitude from surgery is >4 cm. Thus, we would agree with cautious and consistent anterior prolapse correction during both PRST and SCP.
