Single-center retrospective study of the technique, safety, and 12-month efficacy of the MiniArc™ single-incision sling: a new minimally invasive procedure for treatment of female SUI.

This study was conducted to report on the technique, safety, and early efficacy of a single-incision mini-sling to treat female stress urinary incontinence (SUI). Women suffering from SUI were offered a single-incision approach to place a suburethral polypropylene mesh tape in a position similar to that of a transobturator sling without passage of needles through the groin. Retrospective data was collected on 61 patients that received the new MiniArc™ single-incision sling at a single center in the United States. Patient selection and concomitant procedures were determined by the senior authors at the center, and the senior authors were the primary surgeons in all cases. Procedures were completed under general, regional, or MAC anesthesia as determined by the surgeon. Average operative time for the sling procedure alone was short and the average blood loss was 29 cc. There were no intraoperative complications. There was one postoperative adverse event secondary to urinary retention that was resolved by loosening of the sling under local anesthesia in an office setting. The overall cure rate at 12 months determined by physician and patient assessment in 58/61 patients was 91.4%. No patients suffered pain or dyspareunia secondary to the sling, and no erosions or extrusions were reported. In this initial study, the MiniArc™ single-incision sling appears to be a safe approach to treat female SUI, and the early clinical results are encouraging.

Dermal graft-augmented rectocele repair.

We describe a new technique in the surgical treatment of rectocele using a dermal allograft to augment site-specific fascial defect repair of the rectovaginal fascia. The posterior vaginal wall is opened and discrete defects in the rectovaginal fascia are repaired in a site-specific fashion using delayed absorbable suture. A second layer of support is created using a rectangular dermal allograft placed over the site-specific repair and secured to the normal anatomic attachments of the rectovaginal fascia using permanent sutures. The vagina is then closed and routine perineorrhaphy performed as indicated. Forty-three women with advanced posterior vaginal wall prolapse underwent dermal graft augmentation of site-specific rectocele repair over a 1-year period. No major intraoperative or postoperative complications were reported. Thirty women were available for follow-up examination at an average of 12.9 months (range 8-17). The average patient age in the follow-up group was 63.6 +/- 10.9 years (range 33-79) and average parity was 2.8 +/- 1.5 (range 0-7). Using the Pelvic Organ Prolapse Quantification score, the average measurement of point A(p) was 0.25 preoperatively and -2.4 postoperatively, whereas point B(p )was 0.9 preoperatively and -2.5 postoperatively. Using a point A(p) measurement of -0.5 or greater to define surgical failure, 28/30 (93%) of women were noted to have surgical cure on follow-up. Site-specific rectocele repair augmented with dermal allograft is associated with high cure rates and minimal complications. It recreates normal anatomic support and is easily adapted into current surgical procedures for rectocele repair.

Tension-free vaginal tape: outcomes among women with primary versus recurrent stress urinary incontinence.

OBJECTIVE: To evaluate the outcomes of tension-free vaginal tape in the treatment of primary versus recurrent genuine stress urinary incontinence. METHODS: A retrospective, multicenter study of 245 consecutive women who were treated with tension-free vaginal tape for genuine stress urinary incontinence (157 for primary and 88 for recurrent genuine stress urinary incontinence) over a 27-month period was performed. Concurrent surgical repairs were performed as required. Subjective and objective outcome data were assessed from routine postoperative visits. Office and hospital records were reviewed to determine patient characteristics, intraoperative findings, and surgical outcomes. RESULTS: Women with recurrent genuine stress urinary incontinence were older (mean age 64.6 versus 59.4 years, P =.004) than those with primary incontinence; they were less likely to have an intact uterus (22.7% versus 66.9%, P <.001), and were more likely to have intrinsic sphincter deficiency (70.5% versus 47.1%, P <.001). The mean duration of follow-up was 38 (+/-16) weeks. Cure rates among patients with recurrent versus primary genuine stress urinary incontinence were similar (85% and 87%, respectively, P =.23). Complication rates were similarly low in both groups (4.5% versus 7.6% for recurrent and primary genuine stress urinary incontinence, respectively, P =.35). Postoperative voiding dysfunction occurred at low rates in both groups. CONCLUSION: Tension-free vaginal tape is a highly effective treatment among patients with recurrent stress incontinence, with outcomes comparable with those among patients with primary incontinence.

Release of tension-free vaginal tape for the treatment of refractory postoperative voiding dysfunction.

OBJECTIVE: To report our experience with surgical release of tension-free vaginal tape (TVT) for the treatment of persistent post-TVT voiding dysfunction. METHODS: A total of 1175 women underwent TVT placement for treatment of genuine stress urinary incontinence and/or intrinsic sphincter deficiency over a 2-year period. Additional procedures and vaginal repairs were performed as indicated. Among these patients, 23 women (1.9%) had persistent voiding dysfunction (urinary retention, incomplete bladder emptying, or severe urgency or urge incontinence) refractory to conservative management. This cohort underwent a simple vaginal TVT release procedure, performed on an outpatient basis. Preoperative characteristics, intraoperative, and postoperative details were assessed by review of operative notes, medical records, and office notes. Continence status was assessed using subjective and objective information. RESULTS: Mean age was 67 years (range 46-86 years), and the mean interval between TVT placement and release was 17.3 weeks (range 2-69 weeks; median 8.6 weeks). For the release procedure, there were no intraoperative complications, and all patients were discharged on the day of surgery. All cases of impaired emptying were completely resolved, and all cases of irritative symptoms were resolved (30%) or improved (70%) by 6 weeks. Fourteen (61%) patients remained continent 6 weeks after the release procedure, six (26%) were improved over baseline, and three patients (13%) had recurrence of stress incontinence. CONCLUSION: Refractory voiding dysfunction after TVT is a relatively uncommon situation and can be successfully managed with a simple midline release procedure. In most cases, the release procedure does not compromise overall improvement in symptoms of stress incontinence.

Levatorplasty release and reconstruction of rectovaginal septum using allogenic dermal graft.

The goal of reconstructive vaginal surgery include: restoration of normal anatomy, as well as maintaining visceral and sexual function. Rectocele repair can be performed utilizing a number of techniques, however some of these techniques severely distort the posterior vaginal wall anatomy and subsequently may result in dyspareunia. We report two patients with postoperative dyspareunia following levatorplasty technique for the treatment of rectocele. The patients elected to have their levatorplasty released and their rectovaginal septum reconstructed utilizing allogenic dermal graft. Postoperatively both patients are sexually active without evidence of dyspareunia or rectocele.

Laparoscopic Burch colposuspension for recurrent stress urinary incontinence.

STUDY OBJECTIVE: To evaluate the effectiveness of laparoscopic Burch colposuspension in the treatment of recurrent stress urinary incontinence in women with previous vaginal or abdominal retropubic continence surgery. DESIGN: Retrospective analysis over 36 months (Canadian Task Force classification III). SETTING: Community hospital. PATIENTS: Thirty-three consecutive patients. INTERVENTION: Laparoscopic Burch colposuspension. MEASUREMENTS AND MAIN RESULTS: Data were obtained by retrospective chart review, telephone interviews, and follow-up physical examinations. Of the 33 patients, 17 (52%) had undergone open retropubic procedures (Burch or Marshall-Marchetti-Krantz), 11 (33%) had had vaginal retropubic needle suspension, and 5 (15%) pubovaginal sling operation. Additional laparoscopic and/or vaginal reconstructive surgery was completed in 32 women (97%) at time of laparoscopic Burch. Average overall operating time was 165 minutes (range 60-287 min), mean estimated blood loss was 178 ml (range 50-600 ml), and hospital stay was 1.1 days. Three intraoperative complications occurred, two cystotomies and one serosal bowel injury. Postoperative objective evaluation over average follow-up of 18.6 months revealed a 90% stress urinary incontinence cure rate. CONCLUSION: Laparoscopic Burch colposuspension is safe and effective treatment of recurrent stress urinary incontinence in women who have undergone previous procedures for retropubic continence.

Repair of a vaginal evisceration following colpocleisis utilizing an allogenic dermal graft.

Vaginal evisceration following colpocleisis is a very rare event and, to our knowledge, there has only been one previous case report. An 86-year-old woman presented to the Emergency Department with acute onset of abdominal pain occurring following a bowel movement. Six months previously, she had undergone a colpocleisis for recurrent vaginal vault prolapse. On presentation to the emergency room, she was noted to have 60 cm of necrotic small bowel protruding through her vaginal introitus. She was taken to the operating room for resection of the small bowel and closure of her colpocleisis. The closure of the vaginal defect was difficult and required a vaginal approach employing an allogenic dermal graft. This was accomplished and the patient had an uneventful recovery and was discharged home. At 18 months followup, she has had no complication or recurrence. Evisceration following colpocleisis is a rare event, but can be very difficult to manage and we suggest consideration of employing a graft to reinforce the repair.

Laparoscopic management of urinary incontinence, ureteric and bladder injuries.

The present review focuses on the most recently published English language literature, and addresses results and complications associated with the laparoscopic approach to urinary incontinence, anterior vaginal wall prolapse, and lower urinary tract injury. Laparoscopic Burch procedures continue to show equal efficacy, but lower morbidity as compared with conventional open techniques. Lower urinary tract injuries may also be managed effectively using the same techniques as those employed in open procedures. Laparoscopy continues to be considered a mode of surgical access, and is effective in treating urinary incontinence, anterior vaginal wall prolapse, and lower urinary tract injuries.

Vaginal configuration on MRI after abdominal sacrocolpopexy and sacrospinous ligament suspension.

An MRI study was conducted to compare the vaginal configuration of women who had undergone sacrospinous fixation with transvaginal needle suspension or abdominal sacrocolpopexy with retropubic colposuspension with that of normal controls. MRI examination demonstrated that in normal controls the lower vagina formed an acute angle (mean 53 degrees) with the pubococcygeal line and intersected the upper vagina at a mean angle of 145 degrees. In the abdominal repair group the lower vagina intersected the pubococcygeal line at a mean angle of 57 degrees and joined the upper segment at a mean angle of 137 degrees. In the vaginal repair group the lower vagina intersected the pubococcygeal line at a mean angle of 54 degrees and joined the upper segment at a mean angle of 220 degrees. Our study demonstrated that abdominal sacrocolpopexy with retropubic colposuspension more closely restored the vagina to its normal configuration, whereas sacrospinous fixation with transvaginal needle suspension creates an abnormal vaginal axis.

Use of synthetic mesh and donor grafts in gynecologic surgery.

Traditional surgery for the correction of pelvic organ prolapse continues to result in suboptimal long-term cure rates. In an effort to improve clinical outcomes, various new surgical techniques have been proposed and use of synthetic and donor graft has been advocated. Although the technique of graft placement for the correction of anterior, posterior, and apical vaginal wall reconstruction is easy to perform, controversy exists regarding the optimal choice of material. Synthetic materials have the advantage of being readily available, cost-effective, and consistent in quality, but may present with significant complications, including infection and erosion. In contrast, autologous and heterologous donor grafts provide naturally occurring biomaterials that may undergo desired remodelling, but the in vivo tissue response is still not fully understood. The use of graft materials is still in an early period of evaluation and it is expected that its use will steadily rise with increasing experience and new product development. The following review analyzes our current experience with the use of graft materials in reconstructive pelvic surgery.

Abnormal spinal curvature and its relationship to pelvic organ prolapse.

OBJECTIVE: Intra-abdominal vector forces have been implicated in the development of genital prolapse. Because the normal spinal curvature appears to protect the pelvic cavity from direct upper abdominal forces, variations in spinal curvature may alter these vector forces and possibly potentiate the development of pelvic organ prolapse. This study was undertaken to evaluate the relationship of spinal curvature and pelvic organ prolapse, specifically, the loss of lumbar lordosis or pronounced thoracic kyphosis. STUDY DESIGN: A total of 363 patients referred for various complaints of urinary incontinence or pelvic organ prolapse were included in this multicenter, prospective, case-control study. All patients underwent a detailed history with site-specific examinations; pelvic organ prolapse was quantitatively assessed according to the POPQ (pelvic organ prolapse quantitation) staging system. Spinal curvature was measured with a flexi-curve malleable rod when patients were in a fully erect position. Spinal curvature was then transferred to graph paper by tracing the flexi-curve. Thoracic and lumbar curvatures were determined by measuring thoracic and lumbar lengths and widths, respectively. RESULTS: Ninety-two patients had abnormal spinal curvature according to the study criteria. Complete loss of lumbar lordosis was found in 69 patients. Of the 92 patients with an abnormal curvature, 84 currently had or previously had pelvic organ prolapse (sensitivity, 91%). When compared with patients with a normal curvature, patients with an abnormal spinal curvature were 3. 2 times more likely to have development of pelvic organ prolapse (odds ratio, 3.18; 95% confidence interval, 1.46 to 6.93; P =.002). There was no difference in the number of vaginal deliveries, weight of largest vaginally delivered infant, or body mass index. Only 11% (8/72) of patients with stage 0 prolapse had an abnormal spinal curvature, which increased to 30% (28/99) in patients with stage III prolapse (P =.042). CONCLUSION: An abnormal change in spinal curvature, specifically, a loss of lumbar lordosis, appears to be a significant risk factor in the development of pelvic organ prolapse.

Laparoscopic paravaginal repair plus burch colposuspension: review and descriptive technique.

The objective of this article was to review the available literature on laparoscopic Burch urethropexy cure rates and describe the authors' laparoscopic technique and experience with Burch urethropexy and paravaginal repair. A MEDLINE search (1991 to 1999) was performed for articles describing the laparoscopic Burch urethropexy using suture to elevate and stabilize the paraurethral tissue. Also a retrospective chart review of the authors' 171 consecutive patients between January 1997 and December 1999 was done. The laparoscopic Burch urethropexy and paravaginal repair is described using an open laparoscopic technique with 3 accessory ports for access. A transperitoneal approach is taken to gain access to the space of Retzius. The anterior vaginal wall and its paravaginal defects, if present, are identified. Nonabsorbable sutures are placed in a conventional fashion. The paravaginal repair is used for support of the anterior vaginal wall proximal to the urethral vesical junction and the Burch urethropexy distal to the vesical neck. An average of 6 sutures are used for the paravaginal repair and 4 sutures for the Burch urethropexy. Cystoscopy is performed to ensure no breech of lower urinary tract integrity. In all, 20 articles describing a laparoscopic Burch urethropexy and postoperative cure rate were identified. Cure rates ranged from 69% to 100%. A review of our experience revealed 130 of 171 patients had a Burch urethropexy and paravaginal repair, 23 of 171 patients a Burch urethropexy alone, and 18 of 171 patients a paravaginal repair alone. Of the authors' 171 patients, 4 (2.3%) had injury to the lower urinary tract during laparoscopic Burch urethropexy or paravaginal repair. All 4 injuries were cystotomies, 2 in patients with previous open retropubic urethropexies. No ureteral ligations or intravesical placement of suture was diagnosed. Other surgical parameters for the laparoscopic Burch uethropexy and paravaginal repair include an estimated blood loss of 50 mL, average hospital stay of less than 23 hours, and an average operative time of 70 minutes. All patients had their surgery completed via laparoscopy. The literature review and our personal experience suggests that the laparoscopic Burch urethropexy and paravaginal repair are safe and effective alternatives to traditional laparotomy for the treatment of genuine anatomic stress urine incontinence and cystourethrocele resulting from lateral vaginal wall defects.

Frequency of lower urinary tract injury at laparoscopic burch and paravaginal repair.

STUDY OBJECTIVE: To estimate the rate of injury to the lower urinary tract during laparoscopic Burch urethropexy and/or paravaginal repair. DESIGN: Retrospective analysis over 30 consecutive months (Canadian Task Force classification II-2). Setting. Community hospital. PATIENTS: One hundred seventy-one consecutive patients. INTERVENTION: Laparoscopic Burch urethropexy and/or paravaginal repair. MEASUREMENTS AND MAIN RESULTS: All patients had intraoperative transurethral videocystoscopy performed with intravenous injection of indigo carmine dye to assess potential injury to bladder or ureter. Four women (2.3%, CI -0.71-0.03) had injury to the lower urinary tract. All four injuries were cystotomies, two in women with previous open retropubic urethropexy. No ureteral ligation or intravesical placement of suture was diagnosed. CONCLUSION: Despite most patients having both Burch urethropexy and paravaginal repair, the lower urinary tract injury rate of 2.3% is much lower than the reported 10% for patients having Burch urethropexy alone performed by laparotomy. Reported benefits of laparoscopy including less blood loss and better visualization may explain this result.

A retrospective comparison of abdominal sacrocolpopexy with Burch colposuspension versus sacrospinous fixation with transvaginal needle suspension for the management of vaginal vault prolapse and coexisting stress incontinence.

The objective of this study was to compare the surgical outcome of abdominal sacrocolpopexy and Burch colposuspension with sacrospinous fixation and transvaginal needle suspension in the management of vaginal vault prolapse and coexisting stress incontinence. One hundred and seventeen women with vaginal vault prolapse and coexisting stress incontinence were surgically managed over a 7-year period. The first 61 consecutive women who underwent sacrospinous fixation and transvaginal needle suspension comprised the vaginal group, and the following 56 consecutive women who underwent abdominal sacrocolpopexy and Burch colposuspension comprised the abdominal group. Office records were reviewed to assess the presence of recurrent prolapse and urinary incontinence during postoperative follow-up. Objective follow-up was available for 101 women. Mean duration of follow-up was 24.0 +/- 15 months for the vaginal group, and 23.1 +/- 12.6 months for the abdominal group. The incidence of recurrent prolapse to or beyond the hymen (33% vs. 19%, P=0.0505) and lower urinary tract symptoms (26% vs. 13%, P = 0.0506) were significantly higher in the vaginal group than in the abdominal group. Our data suggest that the combined abdominal approach has a lower incidence of recurrent prolapse and lower urinary tract symptoms than the combined vaginal approach in managing vaginal vault prolapse and coexisting stress incontinence.

Rectovaginal fistula repair utilizing a cadaveric dermal allograft.

Rectovaginal fistula repair is commonly performed through the vagina. When recurrent fistulae occur, healthy tissue such as a muscle or fat pad may be interposed to facilitate healing and prevent recurrence. A woman developed a postpartum rectovaginal fistula after her third-degree perineal laceration failed to heal completely. Two subsequent fistula repairs were performed, with recurrence following each procedure. The fistula was ultimately repaired by performing a layered closure and interposing a cadaveric dermal allograft between the rectovaginal septum and vaginal epithelium. Allogenic cadaveric graft may be a viable alternative to traditional autologous flaps for the repair of recurrent or complicated rectovaginal fistulae.

Laparoscopic treatment of vesicouterine fistula.

Vesicouterine fistula are rare disorders that are most commonly repaired by laparotomy. A specific type of vesicouterine fistula, vesicocervical fistula, was repaired successfully by laparoscopy. This procedure was associated with minimal blood loss and morbidity, and the patient's hospital stay was less than 24 hours. (J Am Assoc Gynecol Laparosc 6(3):339-341, 1999)

Laparoscopic management of recurrent vesicovaginal fistula.

Vesicovaginal fistula repair is most commonly undertaken via a transvaginal approach. We report a recurrent case of vesicovaginal fistula which was ultimately repaired using a laparoscopic approach. The fistula followed a hysterectomy and persisted despite two operations using the Latzko partial colpocleisis and prolonged catheterization. The fistulous tract was ultimately repaired by closing the vagina and bladder with an interposing omental flap utilizing a laparoscopic approach.

Computed tomography comparison of bony pelvis dimensions between women with and without genital prolapse.

OBJECTIVE: To compare bony pelvis dimensions between white women with and without genital prolapse using computed tomography (CT) pelvimetry. METHODS: Thirty-four multiparous white women with vaginal prolapse beyond the hymen and 34 matched white controls with no signs or symptoms of pelvic support defects underwent CT pelvimetry. The anteroposterior and transverse diameters of the pelvic inlet, the interspinous diameter of the midpelvis, and the intertuberous diameter of the pelvic outlet were measured. Post hoc power analysis showed that 22 women were needed in each group to detect a 10% difference in the pelvic dimensions between groups, with an alpha error of 1% and a beta error of 10%, resulting in a 90% power. RESULTS: Mean (+/- standard deviation [SD]) age of the subjects was 63.4+/-8.3 years, compared with 62.9+/-7.8 years for controls. Mean parity of the subjects was 3.3+/-1.7, compared with 3.6+/-1.7 for controls. Mean (+/- SD) anteroposterior (12.5+/-1.3 versus 12.8+/-1.0 cm), interspinous (11.5+/-0.8 versus 11.2+/-0.9 cm), and intertuberous (10.0+/-1.0 versus 9.8+/-0.8 cm) diameters were not significantly different between study groups. Mean transverse diameter of the pelvic inlet was significantly greater in women with prolapse than those without prolapse (12.9+/-0.7 versus 12.4+/-0.6 cm, P = .006). CONCLUSION: Women with advanced vaginal prolapse have larger transverse inlet diameters than do women with normal pelvic support.
