JK,
I did not have incontinence prior to my prolapse surgery but sometimes a prolapse can mask incontinence. When your bladder drops down, it makes it more difficult to urinate due to simple gravity (the urine cannot flow upward and out as it would need to when the bladder drops). My doctor told me that after the prolapse surgery I might have incontinence and so he did a urodynamics test to see if I was likely a person who would have incontinence once my prolapse was addressed. It turned out that I was and so he made some adjustments during my surgery to address incontinence as well. I do not recall him making a distinction between urge and stress incontinence but maybe he would have if that had been what I was primarily there for.
