What condition does the Marshall-Marchetti operation primarily address?

The Marshall-Marchetti operation primarily addresses female urinary incontinence. This surgical procedure is designed to provide support to the bladder neck, enhancing continence by correcting issues related to pelvic floor support and urethral function. Female urinary incontinence often occurs due to factors such as childbirth, aging, or pelvic surgery that weaken the pelvic support structures, leading to involuntary leakage of urine during activities such as sneezing, coughing, or exercise.

The Marshall-Marchetti operation involves placing a stitch to elevate the bladder neck and can effectively restore normal function in women suffering from stress urinary incontinence. This correction can lead to significant improvements in a patient's quality of life, reducing embarrassment and enhancing overall well-being.

Other conditions listed, such as male urinary incontinence, kidney stones, and urinary tract infections, relate to different issues and would require other treatment modalities, thus confirming that the focus of the Marshall-Marchetti procedure is specifically on female urinary incontinence.
