Surgical treatment for stress urinary incontinence (SUI) using transobturator tape insertion is widely accepted. However several postoperative complications were reported in the literature including infections, abscess and fistula formation. Here we report a case of 57 year old female who presented with abscess and left vaginocutaneous buttock fistula 7 years after transobturator polypropelene tape insertion. Treatment included abscess drainage with dissection of the fistulous tract and removal of the left arm of the transobturator tape along with antibiotic coverage. Sinus drainage stopped after 3 days. Stress urinary incontinence didn't recur. Suspicion of fistula formation should rise in patients presenting with bothersome vaginal or cutaneous discharge after transobturator tape insertion. This case is particular since it describes a fistula complication with polypropelene tape which is unusual with this type of tapes. Treatment of such complication should always consist of surgical removal of the mesh to allow closure of the fistulous tract. [less ▲]

Management of pelvic organ prolapse (POP) may be conducted by abdominal (laparotomy or laparoscopy) or vaginal approach, with or without mesh repair, mainly depending on the surgeon’s expertise. The aim of this study was to determine the trends in surgical management of POP in French-speaking Belgium. The GGOLFB Gynecologic surgery working group initiated a registry of the patients surgically treated for POP from eight centers in French-speaking Belgium. In this prospective multicentric study, conducted between June 2010 and January 2013, we analyzed the clinical and surgical data, the postoperative results at 4 months, the intra and postoperative complications, and reoperation rates. A total of 394 patients were registered in the database. Surgical POP repair was performed vaginally in 83.5 % of the patients, with prosthetic material in 70.2 % of the cases. In case of abdominal procedure, surgery was mainly (93.5 %) performed by laparoscopic sacrocolpopexy. The most common intraoperative complications were severe bleeding (2.3 %), bladder (2 %), and bowel (0.2 %) injuries. At 4 months, the total reoperation rate was 11.3 %. The anatomical success rate (POP-Q < 2) was 87.5 % with 2.1 % of reoperation for recurrence. Mesh exposure was observed in 9.8 % of the cases. Surgery for stress urinary incontinence (SUI) was reported in 5.1 % of the patients. The analysis of the current urogynecological practice in French-speaking Belgium shows that vaginal mesh repair is the preferential approach used for management of POP in the participating centers. The creation of a national database will help to evaluate the global trends in prolapse surgery and the potential impact of the FDA notification in the management of POP in Belgium. [less ▲]

INTRODUCTION AND HYPOTHESIS: The aim of the study was to correlate histological and biomechanical characteristics of the vaginal wall in women with pelvic organ prolapse (POP). METHODS: Tissue samples were collected from the anterior [point Ba; POP Questionnaire (POP-Q)] and/or posterior (point Bp; POP-Q) vaginal wall of 15 women who underwent vaginal surgery for POP. Both histological and biomechanical assessments were performed from the same tissue samples in 14 of 15 patients. For histological assessment, the density of collagen and elastin fibers was determined by combining high-resolution virtual imaging and computer-assisted digital image analysis. For biomechanical testing, uniaxial tension tests were performed to evaluate vaginal tissue stiffness at low (C0) and high (C1) deformation rates. RESULTS: Biomechanical testing highlights the hyperelastic behavior of the vaginal wall. At low strains (C0), vaginal tissue appeared stiffer when elastin density was low. We found a statistically significant inverse relationship between C0 and the elastin/collagen ratio (p = 0.048) in the lamina propria. However, at large strain levels (C1), no clear relationship was observed between elastin density or elastin/collagen ratio and stiffness, likely reflecting the large dispersion of the mechanical behavior of the tissue samples. CONCLUSION: Histological and biomechanical properties of the vaginal wall vary from patient to patient. This study suggests that elastin density deserves consideration as a relevant factor of vaginal stiffness in women with POP. [less ▲]

INTRODUCTION AND HYPOTHESIS: The purpose of this study was to analyze the histomorphometric properties of the vaginal wall in women with pelvic organ prolapse (POP). METHODS: In 15 women undergoing surgery for POP, full-thickness biopsies were collected at two different sites of location from the anterior and/or posterior vaginal wall. Properties of the precervical area (POP-Q point C/D) were compared with the most distal portion of the vaginal wall (POP-Q point Ba/Bp) using histological staining and immunohistochemistry. The densities of total collagen fibers, elastic fibers, smooth muscle cells, and blood vessels were determined by combining high-resolution virtual imaging and computer-assisted digital image analysis. RESULTS: The mean elastin density was significantly decreased in the lamina propria and muscularis layer of the vaginal wall from the most distal portion of the prolapsed vaginal wall compared with the precervical area. This difference was statistically significant in the lamina propria for both anterior (8.4 +/- 1.2 and 12.1 +/- 2.0, p = 0.048) and posterior (6.8 +/- 0.5 and 10.1 +/- 1.4, p = 0.040) locations, and in the muscularis for the anterior (5.2 +/- 0.4 and 8.4 +/- 1.2, p = 0.009) vaginal wall. There were no statistically significant differences in the mean densities of collagen fibers, smooth muscle cells or blood vessels between the two locations. CONCLUSIONS: In this study, we observed changes in elastin density in two different locations of the vaginal wall from women with POP. The histomorphometric properties of the vaginal wall can be variable from one place to another in the same patient. This result supports the existence of most vulnerable locations within the vaginal wall and the potential benefit of site-specific prolapse surgery. [less ▲]

INTRODUCTION AND HYPOTHESIS: The pathophysiology of pelvic organ prolapse (POP) is incompletely understood. The purpose of this study is to describe the current knowledge about histology of the vaginal wall and its possible involvement in the pathogenesis of pelvic organ prolapse. METHODS: Eligible studies were selected through a MEDLINE search covering January 1986 to December 2012. The research was limited to English-language publications. RESULTS: Investigations of changes in the vaginal tissue that occur in women with genital prolapse are currently still limited and produced contrary results. The heterogeneity of the patients and the control groups in terms of age, parity and hormonal status, of the localization of biopsies and the histological methods as well as the lack of validation of the quantification procedures do not allow clear and definitive conclusions to be drawn. CONCLUSIONS: This review shows that current knowledge of the histological changes observed in women with POP are inconclusive and relatively limited. More studies are needed in this specific field to better understand the mechanisms that lead to POP. [less ▲]

OBJECTIVE: To comparatively define the biomechanical characteristics of the pelvic organs (the vagina, bladder, and rectum), which are crucial for the maintenance of pelvic support. Despite minimal fundamental studies, meshes are increasingly implanted into the vesicovaginal and rectovaginal spaces to replace disrupted native tissues and to treat pelvic organ prolapse. However, the mechanical characteristics of these materials have not yet been compared with those of the “functional unit,” the vagina, bladder, and rectum. METHODS: Samples from 5 fresh female cadavers without prolapse were collected. Uniaxial tension tests under monotonic and cyclic loading were performed and the stress-strain curves obtained. RESULTS: The biomechanical properties of the vaginal, bladder, and rectal tissues differed significantly. We were able to demonstrate a nonlinear relationship between the stress and strain and a visco- hyperelastic behavior with a Mullins effect of damage of the tissues examined. Comparable rigidity was found between the investigated tissues at low strains; however, at large strain levels, marked differences could be observed. The vagina was much more rigid and less extendible than the rectal tissue, which, in turn, was more rigid than the bladder tissue. The anterior and posterior vagina revealed a different stiffness, and the bladder tissue was anisotropic at large strain levels. CONCLUSION: Our results underline the pivotal role of the vaginal tissue for the maintenance of pelvic support. The observed differences with respect to tissue rigidity should have pronounced effects on the physiologic organ function, pointing to the necessity of a differentiated view on using the same prosthetic material for different anatomic locations.

Objective The aim of this study was to explore the nature and rate of surgical intervention after transvaginal Prolift mesh repair for pelvic organ prolapse. Study Design This was a retrospective study of all patients who underwent Prolift mesh repair between January 2005 and January 2009. Patient data were obtained from medical records, and patients were telephoned to check if they had surgery in other hospitals. Results A total of 600 consecutive patients were identified. Of these, 524 patients (87.3%) were included in the study, with a median follow-up duration of 38 months (range, 15–63). Global reoperation rate was 11.6%. Indications of intervention were surgery for urinary incontinence (6.9%), mesh-related complications (3.6%), or prolapse recurrence (3%). Conclusion The global reoperation rate after transvaginal Prolift mesh repair was 11.6%, with urinary incontinence surgery being the most common indication. Rates of mesh complications and prolapse recurrence are relatively low in an experienced team. [less ▲]

INTRODUCTION AND HYPOTHESIS: despite minimal fundamental works, there is an increasing use of meshes in urogynecology. The concept is mainly based on experiences with abdominal wall surgery. We aimed to compare the biomechanical properties of vaginal tissue, abdominal aponeurosis, and skin. METHODS: samples from 11 fresh women cadavers without prolapse were collected. Uniaxial tension tests were performed and stress-strain curves were obtained. RESULTS: biomechanical properties of the vagina, aponeurosis, and skin differed significantly. The aponeurosis was much more rigid and less extendible than the vagina and skin. Vaginal tissue was less rigid but more extendible than skin. There was no difference between the vagina and skin at low strains (p = 0.341), but a highly significant difference at large strains (p = 0.005). CONCLUSIONS: skin and aponeurosis are not suited to predict vaginal tissue biomechanics. We should be cautious when transferring experiences from abdominal wall surgery to vaginal reconstructive surgery. [less ▲]

Introduction and hypothesis The aim of this study was to evaluate, retrospectively, the place of sub-urethral mesh readjustment when treating recurrent stress urinary incontinence (SUI) after TVT-O. Methods Between August 2006 and August 2008, eight patients had recurrent or persistent SUI. They were treated surgically by tightening the pre-implanted sling. Results Medium delay between first surgery and mesh adjustment was 6 months. One patient needed a second TVT-O for rupture of the pre-implanted mesh during adjustment. Among the seven patients who underwent a mesh readjustment, three were cured, three improved, there was one failure. Mean follow-up was 25 months. Conclusions The sub-urethral mesh readjustment is a simple and safe procedure for patients with recurrent SIU after TVT-O procedure. Success rates are high, surgery minimally invasive but long-term follow-up is needed to evaluate efficiency. [less ▲]
