Why do we need prostheses in pelvic reconstructive surgery ?
• The high recurrence rate after surgery for pelvic organ prolapse
(POP) makes the more refined reconstructive surgery
imperative
High failure rate 30% (Olsen AL 1997 Obstet Gynecol)
• The long-term anatomic outcomes of traditional cystocele
repair
High failure rate 37% (Quiroz LH 2006 Contemp Ob/Gyn)
• Therefore, biological and synthetic prostheses merged as adjuvant
materials.
Reasons for surgical failure • Poor patient selection • Suboptimal
surgical technique • Inappropriate choice of suture materials •
Persistence of predisposing risk factors
Poor tissue quality Impaired healing Chronic increased
intra-abdominal pressure
• due to COPD, asthma, or constipation
High-grade cystocele Age 60 or above

2) Does it improve the durability of the repair?
3) Does the graft increase the rate of complication?
History of prosthesis
• Inguinal hernia repair in general surgery 43% recurrence in the
suture repair group 24% in the mesh augmented repair group
• Luijendij R 2000 NEJM
• History of synthetic non-absorbable prostheses 1903 metallic
silver mesh 1938 Nylon 1956 Dacron (Mersilene) 1958 polypropylene
(Marlex)
Advantages of prostheses
• the surgeon can repair all vaginal defects faster and with less
effort.
• Well anatomic support anterior compartment, anchored to
ATFP
• Level II attachment
Posterior compartment, to the level of the ischial spine, • level I
support. (DeLancey 1992 JOL Am J Obstet Gynecol)
• Concomitant surgery POP + SUI using different shaped
materials.
The purposes of prosthesis in pelvic reconstructive surgery
• The purposes of prostheses in pelvic reconstructive surgery
are
to substitute the lacking supportive tissue, to reinforce the
inadequate tissue, to generate new supportive tissue, to
consolidate the insufficient surgical technique.

• A systematic review of 98 articles success rates for apical
support of 78–100% support of all segments of 58–100%
• [Nygaard IE 2004 Obstet Gynecol ].
• Synthetic rather than biological prostheses randomized trial
polypropylene mesh (91% cure) better than cadaveric fascia lata
(68% cure) (p= 0.007) at 1 year follow-up in favor of the
polypropylene mesh group at POP-Q points Aa and C, as well as
overall prolapse stages, sig.

Advantages of procedural kits-I
• Simple and efficient surgical technique Reduced surgery time
Short learning curve Simple and precise transfer of the anchoring
arms. Simplified tension-free system
Advantages of procedural kits-II
• Anatomically-designed needle system Minimally invasive needles
enable easy and accurate placement. The handle’s ergonomic design
provides optimal control over the needle’s insertion.

• Success rate: 95.3% (failure rate 4.7%) recurrent prolapse even
asymptomatic or low grade symptomatic prolapse
• Mesh exposure 4.7% (5/110) 2/ 5 required a surgical

• Prolift seems to be a safe technique to correct POP. However,
anatomical and functional results of a long-term follow-up has not
yet to confirm the effectiveness and safety of the procedure

Take-home message-1
• The high recurrence rate after surgery for pelvic organ prolapse
(POP) makes the more refined reconstructive surgery
mandatory.
• The prostheses are viewed as a scaffold for tissue in-growth and
not as a permanent bridge.
• The use of synthetic prostheses is well established in
sacro-colpopexy,
controversial for repair of anterior and posterior wall
defects.
Take-home message-2 • Synthetic prostheses may have slightly
higher
success rates but higher erosion rate biologic materials: better
tolerated & lower erosion rate.
• Which prostheses (synthetic or biological) is superior in vaginal
surgery currently: inconclusive
• Ideal prostheses with various characters are not available
currently,
synthetic non-absorbable, synthetic absorbable, mixed synthetic, or
biological?
The surgeons themselves should be the decision-makers, not the
manufacturers!
