To the editor: We greatly appreciate the interest in our work as commented on in your journal. In our article published in the Korean Journal of Urology in 2015 [1], we concluded that the Nazca-Tc system is effective and safe in the treatment of advanced anterior vaginal wall prolapse with a low rate of complications after medium-term follow-up. One of our study limitations was sexual inactivity in most of our patients. Thus, in the small number of sexually active cases, dyspareunia was confirmed through direct questioning of the patients or via questionnaire. Pelvic organ prolapse impairs quality of life as a result of vaginal bulge symptoms and change in bladder, bowel, and sexual function. The effect of synthetic meshes on quality of life and sexual function is still being discussed. Overall, the data show that vaginal mesh repair does not interfere with a healthy sexual life. The risk of dyspareunia can be kept to a minimum by ensuring that the mesh lies flat and is placed tension-free [2-4]. In a review article regarding the impact of pelvic organ prolapse surgery on sexual function, Dietz and Maher [5] concluded that sexual function is similar after anterior polypropylene mesh and anterior colporrhaphy.
