<qa>  What is the invasiveness of the SNM procedure?Because of the invasiveness of the SNM procedure, it would be helpful to have a way to predict treatment success. Investigators in this study propose that the urinary microbiome may change in women before and after SNM implantation and hope to describe these changes by conducting this study. Investigators also hope to determine if differences in the urinary microbiome exist in women with a positive response to SNM treatment responders compared to those without symptom improvement non-responders. This hypothesis will be tested by collecting urine samples from subjects with UUI that are already planning on undergoing SNM as part of clinical care before and after their SNM treatment.
