The study is based on Polizu's Clinic experience and it's a retrospective comparative analysis between Prof. Dan Alessandrescu's istmopexy technique and that imagined by the author used in surgical treatment of grade III genital prolapse associated with urinary incontinence and vaginal vault prolapse. The study was effectuated during 15 years. The technique imagined by the author tryes to prevent the development of the enterocele and the rectocele in posterior perineal defects. Our results show that the gravity index was higher in the Dan Alessandrescu technique versus author's technique. However, the later one must be further verified on a larger number of patients in order to allow an accurate statistical evaluation.
