To assess intra- and postoperative complications and to look for long term follow-up results in women with sacrospinous ligament fixation.Between 1988 and 1999, 200 women (mean age 59.8 years, range 33 to 83 years) underwent vaginal unilateral sacrospinous ligament fixation. 172 patients had had prior hysterectomy. In 28 patients concomitant hysterectomy and sacrospinous ligament fixation was performed. Sacrospinous ligament fixation was combined with the following procedures: 109 enterocele repairs (54.5%), 88 anterior colporrhaphies (44%), 57 reconstructions of urogenital diaphragma (28.5%) and 23 posterior colporrhaphies (11.5%). Additional Burch colposuspension and a Stamey procedure were carried out in 7 (3.5%) and 15 (7.5%) patients, respectively.All 200 patients were analysed for intra- and postoperative complications. Urinary tract infection (n = 16, 8.0%), temporary irritation of the sciatic nerve (n = 15, 7.5%), temporary partial ureteral obstruction (n = 11, 5.5%) and blood loss less than 400 ml (n = 7, 3.5%), occurred in the postoperative phase. Long-term data (range from 6 months to 9 years, mean 4.8 years) exist for 123 patients. 119 were completely cured without any signs of urinary incontinence and prolapse. At follow-up 4 patients (3.25%) showed recurrent vaginal vault prolapse. Recurrent cystoceles, rectoceles, enteroceles, were found in 10 cases (8.1%), one (0.8%) and one (0.8%), respectively. Two patients with complete recurrence of vaginal vault prolapse successfully underwent colpectomy and repeated sacrospinous ligament fixation, respectively. CONCLUSIONS. Sacrospinous ligament fixation is an effective and safe procedure with a low recurrence and complication rate.
