Introduction

Aim of our study was to evaluate the prevalence of 'pure' SUI (P-SUI), in a cohort underwent urodynamic test (UD) for urinary incontinence (UI), and the correspondence with UD findings. We also estimated the amount of costs of UD, and if the UD data could change the surgical indications.

Methods

We did a retrospective evaluation of the UD-database selecting 544 women with UI between January 2012 and July 2016. Pure SUI was defined by the International Continence Society criteria (table 1). Two very experienced urologists evaluated data. _x000D_ Data researched were: _x000D_ - Prevalence of clinical and UD P-SUI _x000D_ - Correspondence between clinical P-SUI and UD findings_x000D_ - Accurate estimation in € of a single UD examination, including the human resources and materials used_x000D_ - Total amount of UD costs in € in P-SUI patients_x000D_ - Number of surgical procedures avoided due to UD results_x000D_ - Related avoided surgical costs in € in P-SUI patients_x000D_

Results

SUI was present in 323/544 (59.4%), in this group the prevalence of P-SUI was 20.7% (67/323) while the prevalence of complicated SUI was 79.3% (256/323). _x000D_ The correspondence between the clinical diagnosis of P-SUI and the UD findings was 88% (59/67 patients). For this reason after UD the number of patients with diagnosis of P-SUI decreased to 59/323 with a rate of 18.3%._x000D_ The cost of each UD study was 383 € and the total amount for this cohort of patients was 25.661 €. As consequence of a change of the therapeutic treatment after UD findings we did not performed the scheduled middle urethral sling in 6 patients with a total amount saved of 10.800 €.

Conclusions

UD study detected a relevant prevalence of P-SUI as 1/5 of the amount of the SUI women. The correspondence between clinical and UD findings was high. A total amount cost of P-SUI patients is not negligible respect to the total UD budget. Nevertheless, UD was able to avoid an inappropriate procedure in 9% of the patients.
