Bacterial biofilm formation on vaginal ring pessaries used for pelvic organ prolapse.

INTRODUCTION AND HYPOTHESIS: The objective of this study was to characterize the bacterial biofilm on vaginal ring pessaries used to treat pelvic organ prolapse and investigate the relationship between biofilm phenotype and patient symptoms and clinical signs that are suggestive of inflammation. METHODS: This was a cross-sectional observational study of 40 women wearing a ring-shaped pessary continuously for at least 12 weeks. Participants underwent a clinical examination, and the pessary was removed. Clinical signs were recorded. A swab from the pessary surface and a high vaginal swab were collected from each woman. Participants completed a questionnaire on symptoms. Pessary biofilm presence and phenotype were determined by scanning electron microscopy (SEM). Vaginal and pessary bacterial composition was determined by 16S rRNA gene sequencing. The relationship between biofilm phenotype and symptoms and clinical signs was assessed using logistic regression. RESULTS: SEM confirmed biofilm formation on all 40 pessaries. Microbiota data were available for 25 pessary swabs. The pessary biofilm microbiota was composed of bacteria typically found in the vagina and was categorized into Lactobacillus-dominated (n = 10/25 pessaries, 40%) communities and Lactobacillus-deficient communities with high relative abundance of anaerobic/facultative anaerobes (n = 15/25 pessaries, 60%). While increasing age was associated with presence of a Lactobacillus-deficient pessary biofilm (odds ratio = 3.60, 95% CI [1.16-11.22], p = 0.04), no associations between biofilm microbiota composition and symptoms or clinical signs were observed. CONCLUSIONS: Lactobacillus-deficient biofilms commonly form on pessaries following long-term use. However, the contribution of biofilm phenotype to symptoms and clinical signs remains to be determined.

International Continence Society best practice statement for use of sacral neuromodulation.

AIMS: Sacral neuromodulation (SNM) is an accepted therapy for a variety of conditions. However, despite over 20 years of experience, it remains a specialized procedure with a number of subtleties. Here we present the recommendations issued from the International Continence Society (ICS) SNM Consensus Panel. METHODS: Under the auspices of the ICS, eight urologists, three colorectal surgeons and two urogynecologists, covering a wide breadth of geographic and specialty interest representation, met in January 2017 to discuss best practices for neuromodulation. Suggestions for statements were submitted in advance and specific topics were assigned to committee members, who prepared and presented supporting data to the group, at which time each topic was discussed in depth. Best practice statements were formulated based on available data. This document was then circulated to multiple external reviewers after which final edits were made and approved by the group. RESULTS: The present recommendations, based on the most relevant data available in the literature, as well as expert opinion, address a variety of specific and at times problematic issues associated with SNM. These include the use of SNM for a variety of underlying conditions, need for pre-procedural testing, use of staged versus single-stage procedures, screening for success during the trial phase, ideal anesthesia, device implantation, post-procedural management, trouble-shooting loss of device function, and future directions for research. CONCLUSIONS: These guidelines undoubtedly constitute a reference document, which will help urologists, gynecologists, and colorectal surgeons optimize their use of SNM for refractory urinary urgency and frequency, UUI, NOR, and FI.

Anatomic study of prolapse surgery with nonanchored mesh and a vaginal support device.

OBJECTIVE: The purpose of this study was to evaluate the anatomic position and relations to neighboring neurovascular structures of polypropylene implants after vaginal repair with nonanchored mesh and a vaginal support device in a cadaver model. STUDY DESIGN: We undertook anatomic dissection of 6 cadavers, with and without prolapse after surgery. RESULTS: All polypropylene implants were positioned in accordance with the prescribed surgical technique. This surgery reconstructed the entire anterior and posterior pelvic floor compartments without extension beyond the pelvic cavity. A safe distance between the implants and their neighboring neurovascular structures (obturator nerve and vessels, 2.8-3.3 cm; pudendal nerve and internal pudendal vessels, 1.8-2.2 cm; sacral plexus, 2-2.2 cm) was observed. CONCLUSION: Anatomic cadaver dissection confirmed the accurate and safe placement of the polypropylene implants with the use of the prescribed surgical technique.

One-year clinical outcomes after prolapse surgery with nonanchored mesh and vaginal support device.

OBJECTIVE: The purpose of this study was to evaluate outcomes after standardized transvaginal prolapse repair with nonanchored mesh and a vaginal support device. STUDY DESIGN: Postoperative vaginal support was assessed by pelvic organ prolapse quantitative examination after repair of symptomatic stage II/III prolapse. Validated questionnaires assessed pelvic symptoms and sexual function. Visual analog scales quantified experience with the vaginal support device. RESULTS: One hundred thirty-six women received the planned surgery; 95.6% of the women returned for the 1-year assessment: 76.9% of the cases were stage 0/I; however, in 86.9% of the cases, the leading vaginal edge was above the hymen. Pelvic symptoms, quality of life, and sexual function improved significantly from baseline (P < .05). Median visual analog scale scores for vaginal support device awareness and discomfort were 2.6 and 1.2, respectively (0 = none; 10 = worst possible). CONCLUSION: Vaginal support, pelvic symptoms, and sexual function improved at 1 year, compared with baseline, after trocar-free prolapse repair with nonanchored mesh and a vaginal support device.

How could management of rectoceles be optimized?

A posterior vaginal wall prolapse, also known as a rectocele, is a common condition and is an outpouching of the posterior vaginal wall and anterior rectal wall into the lumen of the vagina.1-5 Although more common in parous women, rectoceles of over 1 cm in size have been demonstrated in over 40% of nulliparous women. As rectoceles may be asymptomatic, their true prevalence is not clear. Many women with rectoceles present to their gynaecologist who may not ascertain any anorectal symptoms or perform a rectal examination. Conversely, colorectal surgeons often disregard a vaginal examination.6 Conventionally, gynaecologists have managed rectoceles, but increasingly colorectal surgeons are involved because of the prevalence of anorectal symptoms. There are many surgical techniques for the management of a symptomatic rectocele. There is, however, little data to suggest which is the most effective technique, or whether specific techniques are more appropriate in certain circumstances.7

The pudendal thigh flap for vaginal reconstruction: optimising flap survival.

BACKGROUND: The pudendal thigh fasciocutaneous (PTF) flap is a useful flap in perineal reconstruction, that is reliable when small but is traditionally unreliable when large flaps are raised. Large flaps in particular, are associated with an increased incidence of apical necrosis. Thorough descriptions of the vascular anatomy of this flap have been lacking from the literature, with the current study evaluating this anatomy, aiming to provide the anatomical basis for vascular problems and for techniques to maximise its survival. METHODS: Five unembalmed human cadaveric pelvis specimens were studied. Lead oxide injectant enabled radiographic and dissection analysis of the arterial anatomy of the integument of the perineum. RESULTS: A consistent pattern of vascular supply was found in all specimens. 1: the blood supply to the pelvic floor was supplied sequentially by the posterior labial/scrotal arteries, cutaneous branches from the anterior branch of the obturator artery, and branches from the external pudendal arteries. 2: these vessels ran close to the midline, medial to the PTF flap. 3: the posterior labial/scrotal arteries were deep to the Colles' fascia and the branches from the obturator artery and external pudendal arteries were located superficial to the Colles' fascia. CONCLUSION: This study has demonstrated that the PTF flap is a three vascular territory flap and that the pedicle is situated close to the midline. This may explain why regions of the PTF flap may have a potentially precarious blood supply, and suggests that the PTF flap should be designed more medially. Given the third territory of supply to the apex of the flap, a delay procedure may help to avoid flap necrosis.

Laparoscopic sacral suture hysteropexy for uterine prolapse.

This study aims to describe and review a new method of uterine conservation in pelvic reconstruction for women with uterine prolapse. This is a prospective study of women who have undergone laparoscopic sacral suture hysteropexy. Structured questions, visual analogue patient satisfaction score (VAS), and vaginal examination were undertaken. Follow-up was performed by non-surgical reviewers. From July 2001 until August 2003, a total of 81 women underwent laparoscopic sacral suture hysteropexy for uterine prolapse. At a mean of 20.3 months follow-up, 76 women (93.8%) were available for questioning and 57 (70.3%) attended for examination. Sixty-five women (87.8%) had no symptoms of pelvic floor prolapse, 54 women (94.7%) had no objective evidence of uterine prolapse, and 61 women (82.4%) were satisfied with their surgery (VAS > or = 80%). Laparoscopic sacral suture hysteropexy attaches the posterior cervix to the sacral promontory via the right uterosacral ligament. Follow-up data of laparoscopic sacral suture hysteropexy indicate it to be an effective method in the management of uterine prolapse.

Pubovaginal sling versus transurethral Macroplastique for stress urinary incontinence and intrinsic sphincter deficiency: a prospective randomised controlled trial.

OBJECTIVE: To compare the pubovaginal sling and transurethral Macroplastique in the treatment of female stress urinary incontinence (SUI) and intrinsic sphincter deficiency (ISD). DESIGN: A prospective randomised controlled trial comparing two surgical treatments for SUI and ISD. SETTING: Tertiary referral urogynaecology unit in Australia. POPULATION: Women with SUI and ISD who were suitable for either surgical technique. METHODS: Forty-five women with SUI and ISD were randomly allocated the pubovaginal sling (n = 22) or transurethral Macroplastique (n = 23). Subjective and objective success rates, patient satisfaction and cost measurements at six months and one year following surgery were the primary outcome measures. A telephone questionnaire survey was performed at a mean follow up period of 62 months (43-71). MAIN OUTCOME MEASURE: Comparison of success rates, complications and costs. RESULTS: The symptomatic and patient satisfaction success rates were similar following the sling and Macroplastique with the objective success rate being significantly greater (P < 0.001) following the sling (81%vs 9%). Macroplastique had significantly lower morbidity but was more expensive than the sling (P < 0.001). Response rate at 62 months follow up was 60% in both groups with the sling group reporting better continence success (69%vs 21%) and satisfaction rates (69%vs 29%, P = 0.057). CONCLUSIONS: The pubovaginal sling was more effective and economical than transurethral Macroplastique for the treatment of SUI and ISD. However, transurethral Macroplastique remains an appropriate treatment in selected cases of SUI and ISD.

Urinary and faecal incontinence following delayed primary repair of obstetric genital fistula.

OBJECTIVE: To evaluate: (1) the factors associated with the development of obstetric genitourinary fistula, (2) the incidence of urinary and faecal incontinence following closure of the fistula and (3) the urodynamic findings in women with persistent urinary incontinence. DESIGN: An observational clinical study. SETTING: A specialised fistula unit in a developing country. POPULATION: Women following successful anatomical closure of obstetric genitourinary fistula. METHODS: Fifty-five women were enrolled from the Fistula Hospital in Ethiopia, following obstetric fistula repair. Their case records were reviewed and details regarding (1) antecedent obstetric factors, (2) the site, size and type of fistula and (3) pre-operative bladder neck mobility and vaginal scarring were recorded. All women were questioned regarding symptoms of faecal and urinary incontinence. Women reporting urinary incontinence following fistula repair underwent urodynamic investigations. MAIN OUTCOME MEASURES: Clinical and urodynamic assessment. RESULTS: The mean age of the women was 23 years (range 16-45 years). The fistula in 38 women (69%) followed the first delivery and in 17 women (31%) following a subsequent delivery. The mean duration of labour was four days (range 1-9 days). Forty-four women (80%) had an isolated vesico-vaginal fistula and 11 (20%) had a combined vesico-vaginal and recto-vaginal fistula. The mean diameter of the fistula was 2.9 cm (0.5-6 cm). Successful repair occurred in all women. Thirty women (55%) reported persistent urinary incontinence and 21 (38%) altered faecal continence at follow up. In the former group, urodynamic investigations identified genuine stress incontinence in 17 women (31%), detrusor instability in two (4%) and mixed incontinence in 11 (20%). CONCLUSION: This study demonstrates the high rate of successful closure of the fistula in a specialised fistula unit, but highlights the problem of persistent urinary incontinence following closure.

Stress urinary incontinence after delayed primary closure of genitourinary fistula: a technique for surgical management.

OBJECTIVES: Our purpose was to evaluate the anatomic pathology of severe incontinence after fistula closure and assess a surgical technique for correction of this problem. STUDY DESIGN: Twenty-two women with severe urinary incontinence after fistula closure were recruited, and clinical and urodynamic assessment was performed. A technique combining retropubic urethrolysis, pubovaginal sling, and omental graft was performed in women with genuine stress incontinence (GSI), and continence outcome was assessed at 4 weeks and 14 months. RESULTS: On urodynamic assessment, 9 (41%) had severe GSI with normal compliance, 3 (14%) GSI and poor compliance, 9 (41%) GSI and detrusor instability, and 1 (4%) voiding dysfunction with overflow incontinence. Nine women (41%) with pure GSI underwent continence surgery. Continence outcomes were 78% at 4 weeks and 67% at 14 months. CONCLUSION: The anatomic pathology of GSI after fistula surgery is complex. The surgical technique described is promising with low morbidity and improved continence rates at 4 weeks and 14 months compared with previous techniques.

Abdominal sacral colpopexy or vaginal sacrospinous colpopexy for vaginal vault prolapse: a prospective randomized study.

OBJECTIVE: The purpose of this study was to compare the abdominal sacral colpopexy and vaginal sacrospinous colpopexy in the treatment of vaginal vault prolapse. STUDY DESIGN: Ninety-five women with vaginal vault prolapse were allocated randomly to sacral colpopexy (47 women) or sacrospinous colpopexy (48 women). Primary outcome measurements include subjective, objective, and patient-determined success rates. Secondary outcomes include the impact on bowel, bladder, and sexual function, cost, and quality of life. RESULTS: Two years after the operation (range, 6-60 months), the subjective success rate was 94% in the abdominal and 91% in the vaginal group (P=.19). The objective success rate was 76% in the abdominal group and 69% in the vaginal group (P=.48). The abdominal approach was associated with a longer operating time, a slower return to activities of daily living, and a greater cost than the sacrospinous colpopexy (P<.01). Both surgeries significantly improved the patient's quality of life (P<.05). CONCLUSION: Abdominal sacral colpopexy and vaginal sacrospinous colpopexy are both highly effective in the treatment of vaginal vault prolapse.
