Pelvic prolapse treatment by sacrocolpopexy exposes to certain complications inherent in the placement of prosthetic material.
Bladder erosions mainly result in repeated urinary tract infections, pain and/or hematuria.
The robotic approach could simplify the explantation of prosthetic material when necessary, and allow repair with concomitant autologous tissue.

We present the case of a 61-year-old woman who had a hysterectomy with anterior sacrocolpopexy in 2015, then in 2017 for recurrence of cystocele.
In the aftermath, she consulted many times in front of the appearance of pelvic pain, and disorders of the bladder emptying phase associated with recurrent urinary tract infections. A bladder lithotripsy was performed in October 2021, without diagnosis of prosthetic bladder erosion followed by a cessation of investigations.
This patient suffered from a bladder erosion of her sacrocolpopexy mesh with adjacent bladder stones, associated with a recurrent grade 3 cystocele.
The purpose of this video was to describe the technique of autologous anterior  sacrocolpopexy with fascia lata concomitant with excision of a sacrocolpopexie mesh by robot-assisted transvesical approach.

A one-piece excision of the entire sacrocolpopexy mesh was performed, 	followed by an autologous fascia lata promontofixation. The intervention was performed under robot-assisted laparoscopy in 190 minutes.
The procedure begins with a midline cystotomy until the area of retrotrigonal erosion. Inter-vesico-vaginal dissection releases the mesh from the bladder and vaginal walls, then continues following the prosthesis, which has close contact with the right ureter, until it is fixed to the promontory. The bladder is sutured with 2 vertical hemi reunning sutures of V-lock after placement of doubleJ stents.
We then harvest a strip of fasica lata 11cm long by 2cm wide from the right thigh, which we spread and fix on the anterior vaginal wall and on the vaginal dome, then on the promontory.
There were no intraoperative complications. The patient left the department on D2, the bladder catheter was removed on D15 and the JJ catheters at 1 month.
At 1 month, the anatomical correction was good (C0) and the patient satisfied (PGII 2/7).

The excision of an anterior sacrocolpopexy mesh by robot-assisted transvesical approach, associated with concomitant autologous repair, seems to be a feasible technique and suitable for the management of prosthetic bladder erosions. The use of autologous tissue offers tissue interposition next to the erosion zone, and makes it possible to correct or avoid the recurrence of the prolapse at the same time.
