Final answer:
The two classic retropubic surgical techniques for stress incontinence are Burch colposuspension and midurethral sling.
Step-by-step explanation:
The two classic retropubic surgical techniques for stress incontinence are Burch colposuspension and midurethral sling.
Burch colposuspension involves attaching the front of the vagina to a ligament near the pubic bone, providing support to the urethra. This helps to prevent urine leakage.
Midurethral sling is a procedure where a sling made of synthetic material is placed under the urethra to provide additional support. This procedure is less invasive than Burch colposuspension and has high success rates in treating stress incontinence.
