Efficacy/Safety of Urogynecology Synthetic Mesh Surgery

Condition(s) studied

Investigational drug(s) / intervention(s)

Urodynamic investigations before and after a mesh surgery protocol.: Urodynamic investigations (The urodynamic study included free uroflowmetry, postvoid residual, filling and voiding cystometry, and a urethral pressure profile. The filling cystometry and urethral pressure profile were performed with 37 degrees C normal saline similar to body temperature at an infusion rate of 80 ml/min.

Urodynamic investigations before and after a robotic-assisted sacrocolpopexy protocol.: All surgeries were performed using a DaVinci robotic system (Intuitive® Surgical Inc., Sunnyvale, California,US) with standardized technique and materials. Patients were positioned in dorsal lithotomy and steep Trendelenburg position. Trocars were placed bilaterally, and an assistant port was placed laterally. The peritoneum was opened medial to the ureter to develop an avascular space. The mesh was placed on the posterior and anterior vaginal wall and fixed at the level of anterior longitudinal ligaments S1/S2 by sutures. An intraoperative clinical examination was performed to ensure the mesh was in a tension-free position.

Urodynamic investigations before and after a hysterectomy with trans-vaginal mesh repair: In summary, a vertical incision was made in the anterior vaginal wall to access the vesicovaginal space. The sacrospinous ligament was dissected, and an applicator was inserted and positioned over the SSL. The anchor was fixed to the SSL and the thread was attached to the mesh. The mesh was then adjusted in a tension-free manner, excess mesh was cut, and the incision was closed with suture.

Study summary

This is a retrospective cohort study, aiming at analyzing the efficacy and safety of mesh surgery in pelvic organ prolapse. The synthetic mesh for pelvic organ prolapse include transvaginal mesh or laparotomy, laparoscope, or robotic-assisted laparoscopic sacrocolpopexy with mesh augmentation. The investigators would like to evaluate the efficacy and safety, such as recurrence rates and complication rates for women who underwent urogynecology mesh surgery.

Eligibility

Primary outcome measure(s)

• trans-vaginal mesh repair — Generally in our hospital, pre-operative investigation will be done about 30 days before surgery, post-operative investigation will within 1year after surgery.
  Urodynamic investigations (The urodynamic study included free uroflowmetry, postvoid residual, filling and voiding cystometry, and a urethral pressure profile. The filling cystometry and urethral pressure profile were performed with 37 degrees C normal saline similar to body temperature at an infusion rate of 80 ml/min. 1. The urodynamic data of POP patient with grade \> or = II, will be retrograde analyzed and and compared. 2. Pressure-associated parameters, such as abdominal pressure (Pabd), detrusor pressure (Pdet) will be measured as centimeter of water column (cmH2O), volume-associated parameters, such as infused volume (Vinf), voided volume (Vvod) and intravesical volume (Vive) will measured as ml. Derived parameter will be expressed as their results of calculation.
