Novel hybrid laparoscopic sacrocolpopexy for pelvic organ prolapse with a severe paravaginal defect

Outcome of modified laparoscopic sacrocolpopexy and its effect on voiding dysfunction

BACKGROUND

Laparoscopic sacrocolpopexy (LSC) is an increasingly popular treatment for pelvic organ prolapse (POP) because of its low recurrence rate and safety. Although LSC may improve the voiding function, it may also lead to de novo stress urinary incontinence. The detailed impact of LSC on voiding function and its mechanism remain unclear. Therefore, in this study, we evaluated the impact of LSC on voiding function prospectively by performing a pre- and post-operative urodynamic study in patients with stage 3 or greater POP.

METHODS

Urinary status was evaluated before and 3 months after LSC. Pre- and post-operative evaluations included medical history, clinical examination, urodynamic studies, chain cystography, and residual urine volume measurement. Urinary symptoms were assessed using the International Prostate Symptom Score (IPSS) and the Overactive Bladder Symptom Score (OABSS).

RESULTS

The non-recurrence rate at 3 months was 82.3%. All recurrences involved bladder prolapse. Apart from the fact that there was no significant change in the OABSS, the improvement in IPSS suggests that subjective voiding symptoms have improved. Although the maximum urinary flow rate did not change significantly, the bladder volume at first sensation increased, urinary storage function improved, and residual urine volume decreased. There were no perioperative complications, and none of the patients complained of post-operative difficulty in urination or urinary retention. The retrovesical angle significantly decreased.

CONCLUSIONS

The modified LSC in women with POP provides good functional outcomes in terms of IPSS, post void residual volume (PVR), and urinary storage function.

One-year outcomes of a suture-less laparoscopic sacral hysteropexy using polypropylene Y-mesh grafts and fibrin sealant spray: A prospective comparative study

BACKGROUND

Laparoscopic sacral hysteropexy (SH) is a minimally invasive and effective treatment for uterovaginal prolapse in women who wish to retain the uterus. However, this procedure is limited by a steep learning curve and a long operating time. In this study, we aim to evaluate the surgical outcomes of a modified laparoscopic SH procedure using innovative methods of vaginal mesh attachment, which we hypothesized to be equally effective and time-saving.

METHODS

This was a prospective, parallel, comparative study conducted at a tertiary referral hospital. A total of 34 women with advanced (POPQ [Pelvic Organ Prolapse Quantification] stages ≧ 2) uterine prolapse, who underwent a laparoscopic SH procedure using lightweight polypropylene Y-mesh grafts (ALYTE), were studied. In half (n = 17) of the cases, fibrin sealant spray (TISSEEL) was applied to the meshes fixed at the anterior and posterior vaginal wall with fewer (six vs at least ten) sutures. A detailed comparison of one-year outcomes between groups was performed.

RESULTS

Patient characteristics and perioperative results were comparable between groups with the exception of a significantly shorter total operating time (247.0 vs 292.9 minutes, p = 0.04) noted in the fibrin group. At 1 year, anatomic success (POPQ stage ≦1) rates (76.5% vs 76.5%) were not different between groups. There were eight patients, with four in each group, who had surgical failure. Notably, most (7/8; 87.5%) surgical failures were at the anterior compartment (i.e, recurrent cystocele). No vaginal mesh extrusions were noted. After statistical analysis, we found "cystocele as the dominant prolapse before operation" was a significant predisposing factor for prolapse recurrence (p = 0.019; odds ratio = 8.04).

CONCLUSION

The modified laparoscopic SH procedure using Y-mesh grafts and fibrin sealant spray with fewer vaginal sutures was equally effective as conventional methods but saved time. Laparoscopic SH using Y-mesh grafts might not be as effective in repairing a concomitant dominant cystocele.
