Videocystourethrography with a ring pessary in situ. A clinically useful preoperative investigation for continent women with urogenital prolapse?

Le Fort partial colpocleisis as an effective treatment option for advanced apical prolapse in elderly women

OBJECTIVE

The aim of this study was to evaluate the outcomes of women with advanced apical prolapse who were treated with the obliterative LeFort partial colpocleisis (LFC) procedure.

MATERIALS AND METHODS

We reviewed the medical records of patients who underwent LFC for advanced apical prolapse. We collected data for baseline patient characteristics, co-morbidities, severity of prolapse, operating time, intraoperative injuries, and postoperative complications. Subjective postoperative outcomes and patient satisfaction levels were also assessed.

RESULTS

Ninety-five patients underwent LFC during the study period. Median age of patients at operation was 76.0years. Mean operation time was 121.5 ± 31.9 min. Mean postoperative hospital stay was 3.5 ± 1.6 days. Postoperative complications, which were virtually all urinary symptoms, were present in 29.8% of patients, and 89.3% of patients have been in spontaneous remission. There was one case with perineal wound infection, one case of prolapse recurrence, and one case of de novo rectal prolapse after LFC. The objective success rate of the LFC procedure for all patients was 98.9% (94/95). Most (96%) patients were satisfied with the LFC results and pleased with the improvement in body image.

CONCLUSION

The obliterative LFC procedure had a high success rate and was associated with minimal adverse events for the elderly patients with advanced apical prolapse. This procedure should be considered as a treatment option for the advanced apical prolapse in selected elderly women who do not want to conserve vaginal intercourse, as it offers improvement in quality of life and is associated with a low regret rate.

Urodynamics are necessary for patients with asymptomatic pelvic organ prolapse

AIM

To evaluate the role of pre-operative urodynamics in women with pelvic organ prolapse, who are asymptomatic for urinary symptoms. Correlate urodynamics findings with King's Health Questionnaire (KHQ) responses.

MATERIALS AND METHODS

Retrospective review of prospectively collected data on routine pre-operative urodynamics investigations in women with urogenital prolapse requiring surgery. Patients who were reported to be asymptomatic of urinary symptoms at the urogynaecological clinical consultation, were included for analysis. KHQ and urodynamics data were reviewed.

RESULTS

A 800 records of women having routine pre-operative urodynamics were collected over a 10-year period, were reviewed. 98/800 (12%) were aymptomatic of urinary symptoms and underwent urodynamics. 82/98 (84%) completed the KHQ. 48/98 (49%) had normal urodynamics. 30/98 (31%) had detrusor overactivity (DO). 17/98 (17%) showed occult urodynamic stress incontinence (USI). 3/98 (3%) both DO and USI. 28/98 (29%) had peak flow rate less than 15 mL/s. Forty-five percent of women reporting nocturia had DO. Nine percent had over 100 mL residuals after the free flow study. Routine pre-operative urodynamics changed management in 25/98 (25%) of asymptomatic prolapse patients. TVT was performed in 12 patients. One patient who declined TVT for moderate occult USI, developed new-onset stress urinary incontinence post-operatively.

CONCLUSION

This data show, that an accurate pre-surgical evaluation of patients with prolapse is incomplete without a structured validated questionnaire and urodynamics, due to the high proportion of abnormal KHQ and UDS findings in presumably "asymptomatic" patients.

Clinical relevance of occult stress urinary incontinence (OSUI) following vaginal prolapse surgery: long-term follow-up

INTRODUCTION AND HYPOTHESIS

Patients with genital prolapse and occult stress urinary incontinence (OSUI) are typically treated with prolapse surgery and anti-incontinence surgery based on either a one-step approach or a two-step approach. The aim of our study was to determine whether anti-incontinence surgery is necessary based on the occurrence of OSUI in a study cohort with a long follow-up period.

METHODS

Prolapse surgery was performed using a vaginal approach. Preoperatively, a stress test, a pad test and an assessment of the urodynamics were performed with and without prolapse reduction. Over a follow-up period of 2-8 years, the patients with preoperative evidence of OSUI underwent urogynaecological examinations, stress tests and pad tests.

RESULTS

Of 113 patients with preoperative evidence of OSUI, 57 (50.4 %) were followed up for an average of 5.7 years (range 2-8) after prolapse surgery. Of 57 patients, 16 (28.1 %) had objective and/or subjective stress urinary incontinence (SUI) during the follow-up period, but only 3 patients (5.3 %) required subsequent tension-free vaginal tape (TVT) surgery. In 17 of 57 patients (29.8 %), prolapse recurred.

CONCLUSIONS

Despite the preoperative evidence of OSUI, the manifestation of SUI rarely occurs, with 28.1 % of patients experiencing SUI over long-term follow-up after vaginal prolapse surgery. Anti-incontinence surgery was necessary in only three cases (5.3 %). These results indicate that with the one-step approach, 54 of 57 patients (94.7 %) would have received prophylactic anti-incontinence surgery unnecessarily. In conclusion, we recommend the two-step approach in the management of vaginal prolapse surgery in patients with OSUI.

Management of stress urinary incontinence

Stress urinary incontinence is a common condition that can severely affect a woman's quality of life. Midurethral slings (tension-free vaginal tape and transobturator tape) are becoming first-line surgical treatments for stress urinary incontinence in women. Both procedures gained worldwide popularity immediately after they were introduced. Short operative time, brief hospitalization period, and ease of application have played a role in their acceptance. Sufficient data support the use of both retropubic and transobturator approaches for the placement of a midurethral sling. However, longer follow up in larger populations should assess the long-term reliability of these procedures.

Occult incontinence in women with pelvic organ prolapse - Does it matter?

Objective

Many surgeons perform an anti-incontinence procedure during prolapse surgery in women in whom occult stress urinary incontinence has been demonstrated. Others prefer a two-step approach. It was the aim of the study to find out how many women really need a second operation and if a positive cough stress test with the prolapse reduced is associated with the development of stress urinary incontinence after prolapse surgery.

Methods

233 women were operated for primary or recurrent prolapse without complaining of SUI. Preoperatively, 53/233 women had a full urogynecological workup with the prolapse reduced. Postoperatively, if the patient suffered from stress urinary incontinence, an anti-incontinence surgery was performed.

Results

19/53 (35.8%) women who had a stress test with the prolapse reduced before surgery were defined as occult stress incontinent. Only 3 women (15.8%) of these 19 women developed symptoms of incontinence after prolapse surgery and had to be operated because of that. 18/233 (7.7%) complained of SUI 6 weeks to 6 months after surgery and received a TVT-tape.

Conclusion

The incidence of stress urinary incontinence manifesting after prolapse surgery is low in this study with 7.7%. This fact and the possible severe side effects of an incontinence operation justify a two-step approach if the patient is counseled and agrees. However, there is a small subgroup of women (3/19, 15.8%) with preoperative OSUI and SUI after surgery, who would benefit from a one-step approach. Further research is required to identify these women before surgical intervention.

A review of the concordance of diagnoses made after multi-channel urodynamics and video urodynamics in women with urinary incontinence

OBJECTIVE

Symptoms of urinary incontinence often do not correlate well with the diagnosis provided by urodynamic investigations. Video urodynamics has been described as the "gold standard" investigation for patients with lower urinary tract symptoms. The aim of our study was to determine the concordance of diagnoses made on multi-channel and video urodynamics in women presenting with urinary incontinence to a tertiary care urogynaecology unit.

MATERIALS AND METHODS

We performed a retrospective chart review of 38 women who had video urodynamics and a multi-channel study completed within a one-year period. All patients had a complete history and pelvic floor assessment. The investigators completing each study were blinded to the clinical diagnoses, the physical findings, and the other urodynamics diagnoses. International Continence Society standards were followed for completion of all urodynamics investigations. Multi-channel studies were completed with the patient lying supine and video studies were performed with the patient sitting on a commode. The level of agreement of the diagnoses was calculated using a kappa (kappa) statistic with 95% confidence intervals (CI).

RESULTS

The median age of subjects was 61 years (range 14-79), with a median duration of lower urinary tract symptoms of 6.0 years (range 0.5-41). Patients had had a median of two previous bladder surgeries (range 0-5). The level of concordance of the two diagnoses gave a kappa of 0.16 (95% CI 0.06-0.26).

CONCLUSIONS

There was poor concordance between the diagnoses made on multi-channel and video urodynamics when the two tests were performed on the same patient. Prospective studies are required to evaluate the reproducibility of diagnoses made on cystometry.

Symptomatic and quality of life outcomes after site-specific fascial reattachment for pelvic organ prolapse repair

The aim of this study was to assess symptomatic and quality of life outcome scores following site specific fascial reattachment surgery for pelvic organ prolapse using the validated Prolapse Quality of Life (P-QOL) questionnaires. One hundred and ninety two women underwent surgery for pelvic organ prolapse; ninety four underwent anterior repair (thirty four of them had vaginal hysterectomy), and ninety eight had posterior repair. Patients filled P-QOL questionnaires 24 hours prior to surgery and a postal P-QOL questionnaire six months post operatively. Pre and post operative questionnaires were paired. Quality of life and symptoms scores were calculated using Wilcoxon signed rank test. One hundred and one women returned their questionnaires and were suitable to include in the study. Forty nine underwent anterior repair (fifteen had vaginal hysterectomy) and 52 underwent posterior repair. Quality of life scores showed significant improvement in the anterior and posterior repair groups with the exception of general health in the anterior repair group and general health and prolapse impact in the posterior repair group. Anterior repair significantly improved urinary voiding and storage symptoms. Posterior repair group showed significant improvement in defecatory symptoms. Both groups showed improvement in sexual function and general prolapse symptoms. Prolapse repair with site specific fascial reattachment results in significant improvement in quality of life scores six months after surgery. Anterior repair improves urinary voiding and storage symptoms and posterior repair improves defecatory dysfunction and urinary voiding. Sexual function improves following prolapse repair with site specific fascial reattachment.

Do overactive bladder symptoms improve after repair of anterior vaginal wall prolapse?

This study aims to evaluate the changes of overactive bladder symptoms to anterior vaginal wall prolapse repair. Ninety-three consecutive women with symptomatic anterior vaginal wall prolapse >or= stage II and coexistent overactive bladder symptoms were prospectively studied using a urinalysis, urodynamics, King's Health Questionnaire (KHQ), Prolapse Quality of Life (P-QOL) questionnaire and pelvic organ prolapse quantification (POP-Q) system before and 1 year after surgery. All women underwent a standard fascial anterior repair. Postoperatively, urinary frequency, urgency and urge incontinence disappeared in 60, 70 and 82% of women respectively (p value < 0.001). The vaginal examination findings as well as the quality of life of the women assessed using KHQ and P-QOL significantly improved after surgery (p value < 0.001). This study has demonstrated that anterior vaginal repair does produce significant improvement in overactive bladder symptoms. A larger longer-term study is required to assess if these changes persist over time.

Urogenital prolapse and occult stress urinary incontinence

BACKGROUND

A 76-year-old female presented to an outside clinic with symptoms of pelvic prolapse; she denied stress urinary incontinence (SUI). The patient had a history of two prior anti-incontinence surgeries. Pelvic examination revealed a grade IV cystocele. No SUI was identified, with or without reduction of the prolapse. Anterior colporrhaphy with cadaveric fascia was performed. Her prolapse symptoms resolved, but she had new-onset severe SUI.

INVESTIGATIONS

Pelvic examination, cystoscopy, urodynamics. DIAGNOSIS OCCULT: SUI unmasked after anterior colporrhaphy.

MANAGEMENT

The patient was referred to our institution where videourodynamics were performed, revealing a well-supported bladder and SUI with Valsalva leak-point pressure of 26 cm H20. A transvaginal polypropylene sling was placed. She had complete resolution of SUI and denied exacerbation of mild urgency.

Reevaluating occult incontinence

PURPOSE OF REVIEW

Occult incontinence is a controversial subject without significant exposure in the literature. Conventionally, it has been assumed to be a marker for increased risk of postoperative stress urinary incontinence (POSUI) after repair of pelvic organ prolapse. The controversy surrounds the performance of prophylactic incontinence procedures based on this assumption. Until 2004 no article in the English language had been published demonstrating an association between occult incontinence and increased risk of stress urinary incontinence after repair of severe pelvic organ prolapse in previously continent women. We will explore the evidence regarding occult incontinence, review the data on intervention trials, and address questions that remain.

RECENT FINDINGS

The limited evidence suggests 11-22% of continent patients with severe pelvic organ prolapse will develop POSUI. New evidence suggests that patients with occult incontinence are at substantially more risk. Since anti-incontinence procedures in patients with occult incontinence reduces the incidence of POSUI (to 0-15%), there appears to be some benefit from screening and intervention. Most studies on the subject are small and limited by their design. Results differ regarding whether a negative stress test can be used to rule out the risk of POSUI.

SUMMARY

Minimal existing evidence in the English language suggests that patients with occult incontinence are at increased risk of POSUI. Outcomes in occult incontinence patients undergoing repair of pelvic organ prolapse need systematic study. Until there is adequate solid evidence on the predictive values of our screening test, we cannot counsel patients regarding our ability to prevent POSUI or protect them from unnecessary procedures.

Vaginal pessaries in managing women with pelvic organ prolapse and urinary incontinence: patient characteristics and factors contributing to success

OBJECTIVE

An aging population has resulted in higher prevalence of urinary incontinence (UI) and pelvic organ prolapse (POP). This study examines a nurse-run clinic and analyzes the factors contributing to successful pessary use.

STUDY DESIGN

A retrospective chart review of 1,216 patients was completed. History, pelvic examination and pessary fitting was done. Data was analyzed utilizing a categorical model of maximum-likelihood estimation to investigate relationships.

RESULTS

Median patient age was 63 years. Median number of pessaries tried was two. Eighty-five percent of post-menopausal women were on hormone replacement therapy (HRT) prior to fitting. Highest success rate of 78% was in the group on both systemic and local HRT. Success rates ranged from 58% for urge incontinence to 83% for uterine prolapse. Prior vaginal surgery was a factor impacting success. In our series highest success rates for fitting were obtained with ring pessaries, ring with support, and gellhorns.

CONCLUSIONS

This model is a viable, option for the conservative management of UI and POP. Local HRT plays an important role in successful pessary fitting. Complications are rare.

Concomitant pelvic organ prolapse surgery with TVT procedure

The aim of this study is to evaluate the efficacy and feasibility of concomitant pelvic reconstructive surgery with tension-free vaginal tape (TVT) procedure to treat pelvic organ prolapse women with urodynamic stress incontinence (USI) or occult USI. Seventy-five women with pelvic organ prolapse and diagnosed as USI or occult USI were enrolled in this study. All patients with USI or occult USI underwent TVT treatment under general anesthesia, combined with transvaginal total hysterectomy (VTH), anterior-posterior colporrhaphy (APC), and/or right sacrospinous ligament suspension (SSS) reconstructive surgeries. The subjective assessment was evaluated by using a visual analog scale (VAS) score and a urinary symptomatic questionnaire. The objective assessment was carried out with a 1-h pad test, cough stress test, and urodynamic examination. Of the 75 patients, 35 patients with grade III uterine prolapse underwent VTH and APC, 30 patients with grade IV uterine prolapse underwent VTH, SSS, and APC, and the other 10 patients who had previous hysterectomy with total vaginal vault prolapse underwent SSS and APC. The mean follow-up interval was 25 months (12-42 months). The mean hospitalization was 5.9 days and the mean catheterization time was 3.8 days. The subjective success rate for the treatment of urine incontinence was 88%, and the objective complete cure rate was 84%. The rate of postoperative complications with persistent urinary urgency, de novo detrusor overactivity, dysfunctional voiding, and tape erosion were 50, 8, 12, and 1.3%, respectively. There were no bladder perforations during the TVT procedure and no perioperative complications requiring conversion to laparotomy. Pelvic organ prolapse women with USI or occult USI can be treated by reconstructive surgeries combined with a TVT procedure to treat and prevent postoperative USI.

Management of the urethral outlet in patients with severe prolapse

PURPOSE OF REVIEW

Numbers of women seeking consultation for pelvic floor disorders, a large portion of which will involve pelvic organ prolapse (POP) and lower urinary tract dysfunction, are expected to reach epidemic proportions within the next decade. A full understanding of the complex impact of pelvic organ prolapse on lower urinary tract function is crucial to successful management.

RECENT FINDINGS

Recent data lend support to the concept that women with POP, but no associated urethral dysfunction, may be best served by a surgical repair that carefully avoids dissection in the periurethral area. Conversely, preoperative evaluation will often reveal bladder outlet obstruction concomitant with 'hidden', 'potential', or 'occult' stress urinary incontinence when the prolapse is reduced. Many of these women will not have incontinence symptoms in daily life. Paradoxically, the mechanical bladder outlet obstruction may induce detrusor instability with subsequent obstructed/overactive bladder symptom complexes not dissimilar to those of men with prostatic bladder outlet obstruction. Anatomic research shows that the vessels and nerves supplying the urethra are particulary vulnerable to surgical techniques used in pelvic organ prolapse repair.

SUMMARY

This mix of obstructed, overactive bladder with hidden stress incontinence increases with degree of POP, and all women with severe prolapse will fair best if evaluated for all three conditions prior to surgical repair.

Combined genitourinary prolapse repair and prophylactic tension-free vaginal tape in women with severe prolapse and occult stress urinary incontinence: preliminary results

OBJECTIVES

Continent patients with a positive stress test demonstrated on repositioning of severe genitourinary prolapse are considered to be at high risk of developing postoperative symptomatic stress urinary incontinence (SUI). Our aim was to evaluate in a prospective study whether a prophylactic, tension-free vaginal tape (TVT) procedure, performed during prolapse repair, may prevent the development of postoperative SUI in these women.

METHODS

Thirty consecutive, clinically continent women (mean age 64.5 +/- 9.04 years) with severe genitourinary prolapse and occult SUI were prospectively enrolled. Occult SUI was defined as a positive stress test with repositioning of the prolapse during the preoperative urodynamic studies. All patients had urethral hypermobility; none had intrinsic sphincter deficiency. In addition to genitourinary prolapse repair, these patients underwent concomitant TVT to prevent postoperative SUI. Patients were followed up for at least 1 year. Repeated urodynamic studies were performed at 3 to 6 months postoperatively. The main outcome measures were postoperative SUI, persistent or de novo detrusor instability, and recurrence of prolapse.

RESULTS

The mean duration of follow-up was 14.25 +/- 3.08 months (range 12 to 24). None of the patients developed postoperative symptomatic SUI. However, three asymptomatic patients (10%) had a positive stress test during their postoperative urodynamic evaluation. Nine patients (30%) had detrusor instability before surgery, which persisted in six (66%) postoperatively. Postoperative de novo detrusor instability was diagnosed in four other patients (13.33%). None of the patients had recurrent urogenital prolapse, nor did they have clinical evidence of bladder outlet obstruction.

CONCLUSIONS

The preliminary results of TVT as a prophylactic procedure in clinically continent women with severe prolapse and occult SUI are encouraging. Long-term follow-up is required to confirm the durability of these results.
