Final answer:
The difference between MMK and Burch's colposuspension lies in the surgical technique and materials used. MMK, an older technique, has been largely replaced by Burch's colposuspension which is less invasive and can be done laparoscopically using the patient's own fascia for support.
Step-by-step explanation:
The difference between the MMK and Burch's colposuspension is that the Marshall-Marchetti-Krantz (MMK) procedure is an older technique that has largely been replaced by the Burch colposuspension. MMK was typically performed via an open surgical approach and involved suturing the bladder neck directly to the pubic bone. However, issues with bone erosion and the invasive nature of the procedure led to the development of the Burch technique. Burch colposuspension, on the other hand, is often done laparoscopically and involves suspending the bladder neck and urethra to the ileopectineal ligament (Cooper's ligament) using the patient's fascia. This creates a hammock-like support to prevent the bladder from descending during stress maneuvers. As a result, the correct answer to the question is:
b) MMK involves the use of synthetic mesh, while Burch's uses the patient's fascia
Both procedures aim to treat stress urinary incontinence by providing additional support to the bladder neck and urethra. It is essential to consult a medical professional to determine which procedure is most appropriate on a case-by-case basis.
