Vaginal vault prolapse is a painful condition in which the vaginal cuff descends. This report presents a case of a 65-year-old obese and diabetic female who was suffering from a third-degree vault prolapse. Conventionally used non-surgical treatments, such as exercises for the pelvic floor, are not as effective as surgical approaches for the treatment of third-degree vault prolapse. Post-hysterectomy vaginal vault prolapse can be treated safely and effectively with abdominal sacral colpopexy using a permanent mesh. Due to several risk factors, such as grand parity, advancing age, and poor lifestyle mainly involving exercise to strengthen pelvic floor musculature, the vaginal route of surgery was employed, which was found to be effective, and thus the treatment was successful. In conclusion, such individualized as well as unique approaches to such rare cases can produce efficacious results.
