Abstract
PURPOSE OF REVIEW Transvaginal mesh kits were widely used to treat pelvic organ prolapse for over a 10-year period in the early 2000s. Due to safety concerns and FDA regulations, these mesh kits are no longer available for use. Thus, current Obstetricians and Gynecologists are likely to encounter these meshes, but may have no previous experience or exposure to the devices making it difficult to adequately monitor, counsel, and care for patients that underwent these types of procedures. This review highlights the most commonly used transvaginal mesh kit types, provides insight into signs and symptoms related to transvaginal mesh complications, and provides guidance for management of mesh complications. RECENT FINDINGS Not all transvaginal mesh will give rise to a complication. If complications do occur, treatment options range from conservative observation to total mesh excision. Management must be customized to an individual patient's needs and goals. SUMMARY Transvaginal mesh kits promised increased durability of surgical repair for pelvic organ prolapse. Safety concerns over time caused these kits to no longer be available for use. Practicing Obstetricians and Gynecologists should be aware of the history of transvaginal mesh and the signs and symptoms of mesh complications.

Abstract
Pelvic organ prolapse (POP) has borrowed principles of treatment from hernia repair and in the last two decades we saw reinforcement materials to treat POP with good outcomes in terms of anatomy but with alarming complication rates. Polypropylene meshes to specifically treat POP have been withdrawn from market by manufactures and a blank space was left to be filled with new materials. Macroporous monofilament meshes are ideal candidates and electrospinning emerged as a reliable method capable of delivering production reproducibility and customization. In this review, we point out some pathways that seem logical to be followed but have been only researched in last couple of years.

Abstract
AIM To evaluate midterm results, tolerance and efficiency of interposition of a transobturator subvesical mesh for the repair of cystoceles. PATIENTS AND METHODS We report the results of a total of 45 consecutive transobturator mesh fixation between March 1, 2005 and March 1, 2007. We used a transvaginal polypropylen tension-free mesh (Prolène, Ethicon, Johnson & Johnson, France) fixed through the obturator foramen. RESULTS Before surgery, all patients had cystocele of more or equal than grade II, according to Baden and Walker classification. Five had grade II cystocele (11%), 36 had grade III (80%) and four grade IV (9%). Thirty-nine women had associated median and/or posterior prolapse (86%). Eleven women had urinary incontinence (24%). The procedure was performed in all cases. Duration of a cystocele cure procedure was 25minutes+/-3.2 (12-32). Mean follow-up was 18 months+/-4.2 (13-29). Vaginal erosion ratio was 6%. There was no mesh infection. The objective success rate was 93%. The satisfaction index was 70%. CONCLUSION Transobturator mesh is a safe and efficient method for anterior segment prolapse repair. This procedure is simple, mini-invasive, reproducible and efficient with low morbidity and good tolerance.

Abstract
The study objective was to review the existing literature regarding complications of anti-incontinence sling procedures. PubMed listings using keywords related to slings and associated complications with no date or language restrictions through May 2007 and the Manufacturer and User Facility Device Experience Database were searched for specific device- and procedure-related complications. Where no information was available, published abstracts were cited. Published reports of complications for all types of anti-incontinence sling procedures are analyzed and reported. Sling-related complications are multiple but can be summarized from studies on 13737 cumulative patients as involving: voiding dysfunction (8 studies, 881 patients, 16.3% average overall incidence [OI]); detrusor overactivity (20 studies, 1950 patients, 15.4% OI); urinary retention (14 studies, 943 patients, 14.2% OI); erosion/extrusion (19 studies, 2197 patients, 6.03% OI); impact on quality of life-dyspareunia (2 studies, 175 patients, 4.3% OI); infections-most often urinary tract infections but severe infections such as abscess are reported (19 studies, 1487 patients, 5.5% OI); hematoma-most often pelvic or vaginal (4 studies, 3691 patients, 2% OI); pain (6 studies, 597 patients, 7.3% OI); abdominal and pelvic organ injury-bladder, urethra, vagina, and intestines (10 studies, 1816 patients, 3.3% OI); systemic complications-deep vein thrombosis, sepsis (case reports); and death (case reports). Cure rates for all slings are as follows: subjective (16 studies, 1541 patients, 95% OI, range 63%-99%), objective (15 studies, 1203 patients, 82% OI, range 51%-97%), and failure (8 studies, 599 patients, 11.5% OI, range 4%-37%). It is likely that sling-related complications are under-reported in the published medical literature and in the Manufacturer and User Facility Device Experience Database. This review reports on the incidence of known complications for all types of slings. Some complications are common to all sling techniques; however, with development of minimally invasive slings, device-related complications are reported and compared.

Abstract
Despite the lack of evidence, augmenting pelvic organ prolapse surgery with biologic graft or synthetic mesh is increasing. The objective of this review is to examine the available grafts and meshes and discuss the current data addressing the use of these implants in correction of apical, anterior, and posterior prolapse. Most of the studies are retrospective with few randomized controlled trials. There is level I evidence suggesting that repair of apical prolapse with abdominal sacral colpopexy using synthetic mesh results in improved outcomes. However, most of the data concerning graft or mesh incorporation in anterior or posterior repairs do not support augmentation with prosthesis.

Abstract
The aim of this study was to describe our experience in the management of bladder injuries occurring at intervesicovaginal dissection during the tension-free vaginal mesh (TVM) procedure. Seven hundred four patients were treated for prolapse by vaginal route using the TVM procedure. Bladder injury was diagnosed during the procedure in five patients. Polypropylene mesh was placed in the intervesicovaginal space after a careful repair of the bladder injury. Major postoperative complications were not diagnosed during the short-term follow up. We describe the occurrence and treatment of bladder injuries during the dissection phase in the TVM procedure. Such injuries can occur during the dissection. Placing an intervesicovaginal mesh is acceptable if cautious bladder repair is performed.

Abstract
We present a case of a 29-y-old woman with rectocele, cystocele, and uterine prolapse who developed a vaginal infection after the placement of a macroporous polypropylene vaginal mesh. Bacteroides melaninogenicus was isolated from the area of the infection. The exposed parts of the mesh were removed and she received treatment with metronidazole and doxycycline. No recurrence of the infection was noted during 12 months of follow-up. However, the patient continued to avoid intercourse due to severe dyspareunia. Vaginal mesh-related infections represent an emerging type of infection that may complicate reconstructive surgery in patients with pelvic organ prolapse.

Abstract
We compared inflammatory response, fibrosis and biomechanical properties of different polypropylene materials from one manufacturer (Tyco Healthcare) in a rat model for primary fascial repair. Full-thickness abdominal wall defects were primarily repaired using 'overlay' technique. Multifilament implants were Surgipro SPM and SPMW, the latter a wider-weave type of the former. Monofilament SPMM implants and polypropylene suture repair (Surgipro II) served as controls. Explants were evaluated macroscopically and changes in thickness, shrinkage and tensile strength were measured. Inflammatory and connective tissue response was assessed on haematoxylin-eosin and Movat stains. Immunohistochemistry was done to localise rat macrophages/monocytes. Multifilament materials induced a shorter acute inflammatory response and more pronounced chronic inflammatory reaction compared to monofilament implants. Macrophages could be found deep in interstices 7.5 by 12.5 microm. No difference in collagen deposition and neovascularisation was observed. At 90 days time point, explants reconstructed with tighter woven multifilament SPM were weaker than sutured or SPMM controls. Overall shrinkage of 10% was comparable for all groups.

Abstract
PURPOSE OF REVIEW The success in the use of the tension-free midurethral sling procedures (tension-free vaginal tape, suprapubic arch, transobturator tape) has dramatically altered the approach to the surgical management of stress urinary incontinence in women and marked a resurgence in the use of mesh. We will analyze the characteristics of synthetic meshes and explain the rationale for using monofilament materials with larger pore sizes. Thus, the purpose of this review is to introduce the surgeon to a variety of commercially available mesh materials and the characteristics that make mesh suitable for use as sling grafts. RECENT FINDINGS Type I macroporous mesh materials appear most suitable for transvaginal implantation. Utilization of these materials in a minimally invasive retropubic or transobturator approach, promising early and intermediate follow-up data has been achieved. The outcome of these procedures in women with urethral hypermobility and genuine stress incontinence seems clear. No controlled data, however, exist to define the role of these procedures in difficult cases of stress incontinence. Newer generations of minimally invasive slings may offer treatment alternatives in these difficult cases. SUMMARY Minimally invasive slings using Type I mesh materials are safe and effective. 'Hybrid' type slings may offer alternatives in difficult cases of stress urinary incontinence.

Abstract
Stamey bladder neck suspension is thought to be an excellent procedure for stress urinary incontinence in selected groups of patients. However we must not ignore the complications of this procedure. We report a case of a patient who developed a delayed reaction with bladder wall erosion to the Dacron buttress used in Stamey urethropexy 19 years before. She was presented with pelvic pain and persisting irritative bladder symptoms. The treatment of choice was cystoscopic removal of suture and buttress. Tissue intolerance is a common problem with the use of different kinds of biomaterials in incontinence surgery. Careful cystourethroscopy is essential for early diagnosis and treatment if pain, infections and severe irritative symptoms occur postoperatively.

Abstract
OBJECTIVES To provide pathologic evidence, using six different sling materials, of the findings from rabbit model studies demonstrating loss of tensile strength and stiffness in porcine and cadaveric sling materials. METHODS Ten rabbits randomized into two survival groups (6 and 12 weeks of age) each had human cadaveric fascia, porcine dermis, porcine small intestine submucosa, polypropylene mesh, and autologous fascia implanted on their anterior rectus fascia. At harvest, hematoxylin-eosin and immunohistochemical staining for CD3, CD20, and MIB-I were performed. A pathologist unaware of the content of the slides quantified the degree of inflammation and fibrosis of each. RESULTS Significant differences were found for inflammation (P = 0.016), eosinophil infiltrate (P = 0.035), and inflammatory rind (P = 0.027) at 12 weeks, with polypropylene mesh having the lowest degree. At 12 weeks, differences were found in the presence of fibrosis/scar formation (P = 0.010) and degree of fibrosis/scar (P = 0.009). Although polypropylene mesh, cadaveric fascia, and porcine dermis all demonstrated a high presence of fibrosis/scar, polypropylene mesh had the greatest overall degree of scar formation at 12 weeks. CONCLUSIONS The inflammation with the cadaveric fascia and porcine materials may cause rapid clinical deterioration compared with autologous fascia and polypropylene mesh. These data provide a possible explanation for prior biomechanical studies demonstrating variations in tensile strength and stiffness of the different materials. The fibrosis and scarring noted with polypropylene mesh may also contribute to a more lasting repair.

Abstract
Many surgical procedures for the repair of pelvic organ prolapse are used nowadays. Reconstructive pelvic surgery continues to evolve while surgeons continue to search the definitive surgical cure and have to choose the most appropriate procedures for their patients. Concerning the vaginal approach procedures, there is an increasing interest in the use of synthetic meshes which are at present widely used for surgical repair of pelvic organ prolapse. Prosthetic repair seems to be more reliable, especially when native tissues are of poor quality. The use of synthetic meshes may also simplify surgical procedures and reduce operative duration and morbidity. Material must be inert, permanent and resistant to infection. Based on authors' and other researchers' published experimental and clinical experience, polypropylene is assumed to be the most appropriate material for the vaginal repair of pelvic organ prolapse. However, since no standardized outcome measure is available, it is difficult to compare the results of surgical procedures. Only in recent studies, the subjective cure rates (patient satisfaction and outcome) have been assessed as well as the objective cure rates determined by the investigators. The subjective cure rate is probably more influenced by the functional outcome and sexual activity than by the anatomical result. Continuous evaluation is necessary to study replacement synthetic materials which should improve the rate of prolapse recurrence and reduce the risk of complications. Randomized controlled trials are required to determine which surgical procedures and type of prosthesis are most suitable. This review evaluates the properties of prosthetic materials, their complications and the most common procedures involved in the use of meshes for pelvic reconstructive surgery.

Abstract
Pelvic organ prolapse and stress urinary incontinence increase with age. The increasing proportion of the aging female population is likely to result in a demand for care of pelvic floor prolapse and incontinence. Experimental evidence of altered connective tissue metabolism may predispose to pelvic floor dysfunction, supporting the use of biomaterials, such as synthetic mesh, to correct pelvic fascial defects. Re-establishing pelvic support and continence calls for a biomaterial to be inert, flexible, and durable and to simultaneously minimize infection and erosion risk. Mesh as a biomaterial has evolved considerably throughout the past half century to the current line that combines ease of use, achieves good outcomes, and minimizes risk. This article explores the biochemical basis for pelvic floor attenuation and reviews various pelvic reconstructive mesh materials, their successes, failures, complications, and management.

Abstract
OBJECTIVES Prosthetic reinforcement in the surgical repair of pelvic prolapse by the vaginal approach is currently on the increase. However, this technique is not without tolerance-related problems. The most frequently described complication is prosthesis exposure, including erosion and delayed healing. It is independent of a granuloma and a major infection as pelvic cellulitis. Its mechanism is associated with defective vaginal healing. The purpose of our study is to define the risk factors for exposure of the prosthetic material. PATIENTS AND METHODS Two hundred and seventy-seven medical records relating to patients undergoing surgery due to pelvic prolapse were included in our study. The treatment of genital prolapse was managed via the vaginal approach with polypropylene mesh. This is a continuous, retrospective study conducted over a period of 24 months. RESULTS Thirty-four cases of prosthesis exposure were observed in the 2 months following surgery, which represents an incidence of 12.27%. The risk factors are concomitant hysterectomy [odds ratio 5.17 (P = 0.001)] and inverted T colpotomy [odds ratio 6.06 (P = 0.01)]. The protective factors are preservation of the uterus and the performance of a minor colpotomy in patients who had already undergone a hysterectomy or in those whose uterus had been preserved [odds ratio 5.16 (P = 0.0001)]. DISCUSSION AND CONCLUSION In our study, we have only found risk factors of operative protocol. In fact, other information as age, menopause status or medical history of the patient is not significant. The uterus must be preserved and the number and extent of colpotomies needed to insert the prosthesis must be limited.

Abstract
INTRODUCTION Prosthetic reinforcement by the vaginal approach for surgical repair of pelvic prolapse is experiencing increasing popularity despite problems with tolerance. The most frequently described complication is prosthesis exposure, also known as erosion or granuloma. The mechanism is associated with defective vaginal healing and is independent of major infection such as pelvic cellulitis. OBJECTIVES The purpose of our study was to define the course of this complication and the best therapeutic strategy for patients with prosthesis exposure. MATERIALS AND METHOD Our continuous and retrospective study conducted over a period of 24 months between January 2002 and December 2003 recorded 34 files. These patients underwent prosthetic treatment via the vaginal approach of genital prolapse associated with prosthesis exposure. The procedure, known as TVM (Tension free Vaginal Mesh), involves the insertion without fixing of a synthetic prosthesis in areas of bladder-vagina and rectum-vagina detachment. RESULTS In 33 cases out of 34, the exposure site was located on the anterior colpotomy scar (97%). These prosthesis exposures were managed in two stages, using antiseptic treatment first. This treatment cured 9 patients (26.47%). In the event of failure, a procedure was carried out under brief general anesthesia on an outpatient basis or during a 24-hour hospital stay. This single resection was sufficient for 20 patients (88%). Two patients nevertheless required a second removal procedure (8%) and one patient a third procedure (4%). To notice, one patient presented with a bladder-vagina fistula after resection. This observation of a bladder-vagina fistula following partial removal led us to recommend a blue test and/or cystoscopy as routine practice for each procedure. CONCLUSION With this new vaginal approach for prolapse repair, it is important to monitor prosthesis exposure. To manage exposures, it is necessary to begin with antiseptic or estrogenic treatment. In the event of failure, a partial resection is warranted. We recommend careful prosthesis resection and systematic verification of the bladder.

Abstract
UNLABELLED Although the etiology of rectocele remains debated, surgical innovations are currently promoted to improve anatomic outcome while avoiding dyspareunia and alleviating rectal emptying difficulties following rectocele surgery. Use of biomaterials in rectocele repair has become widespread in a short time, but the clinical documentation of their effectiveness and complications is limited. Medline and the Cochrane database were searched electronically from 1964 to May 2005 using the Pubmed and Ovid search engines. All English language publications including any of the search terms "rectocele," "implant," "mesh," "biomaterial," "prolapse," "synthetical," "pelvic floor," "biological," and "compatibility" were reviewed. This review outlines the basic principles for use of biomaterials in pelvic reconstructive surgery and provides a condensation of peer-reviewed articles describing clinical use of biomaterials in rectocele surgery. Historical and new concepts in rectocele surgery are discussed. Factors of importance for human in vivo biomaterial compatibility are presented together with current knowledge from clinical studies. Potential risks and problems associated with the use of biomaterials in rectocele and pelvic reconstructive surgery in general are described. Although use of biomaterials in rectocele and other pelvic organ prolapse surgery offers exciting possibilities, it raises treatment costs and may be associated with unknown and potentially severe complications at short and long term. Clinical benefits are currently unknown and need to be proven in clinical studies. TARGET AUDIENCE Obstetricians & Gynecologists, Family Physicians TARGET AUDIENCE After completion of this article, the reader should be able to explain that the objective of surgical treatment is to improve anatomic outcome and alleviate rectal emptying difficulties, describe the efficacy of biomaterials in rectocele repair, and summarize the potential risks and problems associated with use of biomaterials in rectocele and pelvic reconstructive surgery.

Abstract
OBJECTIVES To analyse quantitatively, using stereological methods, the density of the collagen fibres induced by four types of sling materials, and verify by a histopathological analysis the corresponding inflammatory reaction, as fibrosis secondary to sling implantation is considered responsible for restoring urethral support and re-establishing continence in women with stress urinary incontinence, and new synthetic materials that promote adequate fibrosis with the least intensity and duration have been proposed to substitute the aponeurotic sling. MATERIALS AND METHODS The study comprised 70 isogenic white Wistar rats divided into three groups: group A (30 rats) had 8 x 4 mm strips of silicone and porcine small intestine submucosa (SIS) implanted in the abdominal subcutaneous tissues; group B (30 rats) had 8 x 4 mm strips of polycaprolactone and polylactic acid copolymers and monofilament polypropylene (PLP) implanted the abdominal subcutaneous layer; while a control group of 10 rats had dissection and suturing with 5/0 Nylon in the abdominal subcutaneous layer, as used to fix the strips in the other rats. Picro-Sirius staining was used to assess collagen fibres, and haematoxylin-eosin for the histopathological study. At 7, 30 and 90 days after surgery, 10 rats from each group were killed and assessed. RESULTS After 7 days all the materials induced a moderate inflammatory reaction that did not differ from that in the control group. At 30 days there was no difference between the control and polycaprolactone and polylactic acid copolymers, having the least inflammatory reaction. PLP and silicone produced a moderate inflammatory reaction, while the porcine SIS induced a more intense reaction. At 90 days there was a more intense inflammatory reaction in polycaprolactone and polylactic acid copolymers than before but it was less than with PLP and silicone, which again were no different. During this period the inflammatory reaction induced by SIS was greater. The stereological analysis indicated that collagen fibres induced by polycaprolactone and polylactic acid copolymers and PLP were less dense (61% and 65%, respectively), and significantly less than with silicone (85%) and SIS (86%). CONCLUSION PLP was the best nonabsorbable material as it induced a less intense inflammatory reaction than the other tested materials. As porcine SIS was completely absorbed the intense fibrosis induced is useful, as it is exclusively responsible for the urethral support later after surgery.

Abstract
OBJECTIVE The purpose of this study was to examine the histopathologic changes of HMDI (Hexamethylene di-isocyanate) cross-linked porcine dermis grafts used for suburethral sling surgery. STUDY DESIGN Twelve patients underwent reoperation with graft removal for urinary retention or recurrent stress urinary incontinence after transvaginal sling surgery. Tissue specimens were available for pathologic evaluation in 7 patients. Graft specimens underwent histologic preparation including hematoxylin and eosin staining. A single pathologist reviewed the slides blinded to clinical outcomes. RESULTS Histopathologic analyses revealed only limited collagen remodeling, and evidence of a foreign body type reaction was present in some specimens. In cases of recurrent stress incontinence, implants appeared to be completely replaced by dense fibroconnective tissue and moderate neovascularization without evidence of inflammation or graft remnants. CONCLUSION HMDI cross-linked porcine dermal collagen implants result in variable tissue reactions that may have unpredictable clinical outcomes in different patients, raising questions about the overall tolerability and efficacy of these grafts in pelvic reconstructive surgery.

Abstract
AIM To clinically and histologically evaluate inflammatory response following rectocele repair using porcine collagen mesh. METHODS Seventeen patients underwent rectocele repair using porcine collagen mesh. Inflammatory response was assessed by clinical and histological inflammatory grading pre- and postoperatively. Postoperative body temperature, complications and hospital stay was compared with 15 patients undergoing posterior colporraphy. RESULTS Postoperative clinical examination did not demonstrate any inflammatory reaction. There were no significant changes in fibroblast count (P = 0.43), connective tissue density grading (P = 0.54), macrophage count (P = 0.20), inflammatory cell count (P = 0.48), total cell count (P = 0.51), or inflammatory grading (P = 0.87) postoperatively compared with preoperative values. Body temperature was significantly elevated for both the study and control group, although higher for the study group, postoperatively day 1 (P < 0.001). There were no significant differences in hospital stay and postoperative complications. CONCLUSION Porcine collagen mesh was not associated with an adverse inflammatory response at clinical or histological evaluation and appears to be a safe material when used for rectocele repair.

Abstract
OBJECTIVES To report the outcome and complications of a series of tension-free vaginal tape (TVT) operations and compare the results with the literature. MATERIALS AND METHODS A total of 256 cases with a minimum follow-up time of 3 months (May 1998-September 2001) were included (193 isolated TVT, 23 combined with vaginal hysterectomy and 63 combined with prolapse surgery). These cases included 21% of the patients presenting with mixed incontinence, 14% with sphincter deficiency and 9.8% with recurrent incontinence. The isolated TVT were carried out under local anesthesia an ambulatory procedure, the others were done under spinal anesthesia. RESULTS Almost all the patients underwent a clinical check-up after 3 months and 1 year and also underwent urodynamic exploration; they were then questioned by means of a questionnaire after 2 and 3 years. The global cure rate was 90, 91, 83 and 87%, respectively. The authors observed 6.4% of recurrences between 3 months and 1 year and 7.2% between 2 and 3 years. For mixed incontinence at the three first check-ups, the cure rate was 75, 85 and 60%, respectively, with 7.4 and 20% of recurrences between these two intervals. The cure rates of the patients who had presented with sphincter deficiency were 76, 79 and 73%, respectively, with 16% recurrences during the first year. In the case of recurrent incontinence, a cure was obtained in 72 and 71% of cases, with 18% of recurrences. The complications consisted of 5.5% cases of perforated bladder, 0.4% hematomas of the Retropubic space, 3.1% urinary infections, 0.4% urethral injuries, 5.1% transient urine retention, 12.0% de novo urinary urgency and 20% de novo dysuria. It should be noted that half of the pre-operative urgencies had disappeared after the operation. No defective healing and rejection phenomenon was observed. DISCUSSION The authors reviewed the results reported in 35 articles, and compare these with their own results. They also reviewed all the complications encountered, account for them and suggested how they can be avoided. There are discrepancies between the various studies, particularly with regard to the complications. CONCLUSION This minimally invasive operation should be further assessed so that it can demonstrate its effectiveness, and become the "Gold standard". Randomized studies are awaited with this in view.

Abstract
Historically, the choice of sling material for the treatment of urinary incontinence has been based on the surgeon's preference and experience. In general, pelvic surgeons have not differentiated artificial graft materials by their inherent qualities or for biocompatibility in the female pelvis and vaginal wall. The introduction of new artificial graft materials and new methods of implantation for the correction of genuine stress incontinence has generated renewed interest in the "pros and cons" associated with nonabsorbable material use. In this review, we discuss and differentiate sling materials and techniques. We consider some of the physical and biologic qualities of artificial graft materials, present theories and practices associated with the successful use of permanent grafts, and discuss the natural evolution of artificial graft slings to the current use of the tension-free vaginal tape and Suprapubic Arc Sling System (American Medical Systems, Minneapolis, MN).

Abstract
In the last century, the pathophysiology of stress urinary incontinence (SUI) has been investigated and several surgical techniques have been utilized for cure. The most recent evolution in the study of SUI is the minimally invasive tension-free vaginal tape (TVT) procedure, which can be done under local anesthesia and intravenous sedation and is individualized for each patient. The procedure recreates the "hammock" of the anterior vaginal wall and endopelvic fascia with a mesh tape of polypropylene. The cure rates of the initial studies are equal to or better than other anti-incontinence procedures, and the permanent supportive mesh is very well tolerated. The TVT creates a backboard on which the urethra compresses itself when it rotates posteriorly during cough or stress. The procedure accomplishes subjective and objective cure without elevating the bladder neck or altering urethral mobility.

Abstract
Both colpocystourethropexy (colposuspension) and sling operations have been shown to be effective in treating female stress incontinence. The present review discusses the literature available and compares the results and complications of both procedures. Colposuspension can give excellent results as both primary and secondary surgery. Slings also give excellent results, but are prone to complications relating to the sling material and postoperative voiding difficulties. Slings are arguably best reserved for women in whom vaginal scarring makes colposuspension impossible. Colposuspension remains the gold standard operation against which new techniques should be compared.

Abstract
Pelvic organ prolapse is a common worldwide problem. Recent advances in our understanding of its pathophysiology, along with progress made in the evaluation and treatment of pelvic support defects, are discussed. Although the pathophysiology of this condition is still not completely understood, genetic factors and environmental factors are involved. Understanding these factors better will help us to approach treatment of pelvic organ prolapse in a more logical manner. Multiple surgical techniques are available for pelvic relaxation, with a wide range of success rates ranging from 77 to 97% for various procedures. New techniques need to be studied further before being incorporated into routine practice. Better standardization of evaluation methods can help in such clinical studies.
