Multiuse Catheters for Clean Intermittent Catheterization in Urinary Retention: Is There Evidence of Inferiority?

In Europe, urinary retention is managed with single-use catheters but there is uncertainty regarding their superiority over multiuse catheters.

Long-term results of continent catheterizable urinary channels in adults with non-neurogenic or neurogenic lower urinary tract dysfunction

Objectives: To evaluate the long-term results after the construction of a Continent Catheterizable Urinary Conduit (CCUC) in adults. Methods: This study retrospectively reviewed the charts of 41 adults from two tertiary centers who received a CCUC. The demographics, underlying diseases, indications for a CCUC and outcomes such as the reoperation rate and the occurrence of complications were extracted. The patient reported outcome was measured with the Patient Global Impression of Improvement (PGI-I) scale and four additional questions about continence, leakage and stomal problems. Results: Twenty-nine patients were women. The median age at surgery was 32 years, with a median follow-up of 52 months. Twenty-six patients had a neurogenic bladder. The reoperation rate was 48.8%, with a median of 10.5 months after constructing the CCUC. Superficial stomal stenosis was the most common registered complication (20 times) and stoma revision was the most often performed reoperation (12 times). Twenty-four patients completed the PGI-I; the mean improvement rating was 2 (=much better). Conclusion: The construction of a CCUC in adults is associated with a high complication and reoperation rate. The high reoperation rate is in accordance with the sparse literature. Despite this, patients reported 'much better' on the PGI-I.

Outcome and complications of adjustable continence therapy (ProACTTM ) in the treatment of urinary incontinence after transurethral resection of the prostate: A multicenter study

Aim

To evaluate the outcome of adjustable continence balloons in the treatment of stress urinary incontinence (SUI) after transurethral resection of the prostate (TURP).

Methods

In two tertiary centers, adjustable continence balloons were implanted in 29 patients with post‐TURP SUI between 2007 and 2018. Endpoints of this retrospective multicenter study were patient‐reported changes in pad count and complications. Dry was defined as no pad or one security pad.

Results

Preoperative urinary incontinence was mild in 7 (24%), moderate in 12 (41%), and severe in 10 (35%) patients. The median follow‐up duration was 21 (interquartile range [IQR], 11‐43) months. Within 30 days postoperatively, a Clavien‐Dindo grade less than or equal to II complication occurred in 24% of the patients. Reintervention rate was 24%. Six and 12 months after implantation, the International Prostate Symptom Score (IPSS) quality‐of‐life item improved significantly from 5 (IQR, 5‐6) preoperatively to 3 (IQR, 1‐4.5) and 1 (IQR, 0‐3), respectively. At last visit (median 21 months after implantation), the outcome on continence had improved in 76% of the patients, including, 45% dry patients. After a median follow‐up of 28 months (IQR, 13‐63; N = 23), all but one patient reported improvement on the Patient Global Impression of Improvement (PGI‐I) scale. In detail, 10 patients reported “very much better” condition compared with before the implantation, 10 patients “much better,” two patients “a little better,” and one patient “no change.” Daily pad use decreased from three (IQR, 2‐5) to one (IQR, 0‐2) pads/day (P < 0.001).

Conclusions

This is hitherto, the first study reporting results of adjustable continence balloons in the treatment of post‐TURP SUI. The therapy was found to be safe and efficient. The majority of our study population reported improvement on their condition and greater than or equal to 50% reduction in daily pad use.

Long-term follow-up of bladder outlet procedures in children with neurogenic urinary incontinence

INTRODUCTION

Achieving continence in children with neurogenic sphincteric incompetence is a challenge. Awareness of the long-term outcome in this young patient population is important. In the past 25 years, the study institution has built experience in bladder outlet procedures such as bladder neck sling and bladder neck reconstructions.

OBJECTIVE

The objective of this study was to evaluate the long-term outcome on continence and re-intervention rate of bladder outlet procedures in children with neurogenic urinary incontinence at the study institution.

DESIGN

All children who underwent a bladder neck procedure between 1992 and 2017 at the study institution were retrospectively reviewed. Continence at the end of follow-up was the primary endpoint, defined as 'dry' when there was an interval of a minimum of 4 h without urinary leakage. Non-parametric tests were used for statistical analysis.

RESULTS

During this 25-year period, a total of 60 children underwent a bladder outlet procedure, either a bladder neck sling (n = 43) or a bladder neck reconstruction (n = 17). The median age at surgery was 11.6 years (interquartile range [IQR] 7.8-13.9). Concomitant surgery consisted of bladder augmentation in 80% and continent catheterizable urinary channel in 97% of children. Dry rate within 1 year was 38%. After a median follow-up of 10.4 years (IQR 6.5-15.5), 77% of all children were dry. Twenty-five children (42%) needed one or more re-interventions, including redo of the bladder outlet procedure, other type of outlet procedure, bulking agents, bladder augmentation, and bladder neck closure.

DISCUSSION

This study confirms that achieving continence is a challenge. The inconsistent use of the definition of urinary continence creates confusion in the literature and makes comparison of outcome with other studies difficult. Openness of (long-term) results in achieving urinary continence is important and helpful for future patients.

CONCLUSION

On the long term, the majority of children with neurogenic urinary incontinence were dry after a bladder outlet procedure, but a considerable number of patients had a re-intervention. The initial outcome on continence was slightly disappointing. Reporting long-term results is essential and helpful for patient counseling.

Value of urodynamic findings in predicting upper urinary tract damage in neuro-urological patients: A systematic review

AIM

The main goals of neurogenic lower urinary tract dysfunction (NLUTD) management are preventing upper urinary tract damage (UUTD), improving continence, and quality of life. Here, we aimed to systematically assess all available evidence on urodynamics predicting UUTD in patients with NLUTD.

METHODS

A systematic review according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Statement was performed in March 2017. Only neuro-urological patients assessed by urodynamics were included. Any outcome of upper urinary tract function were evaluated.

RESULTS

Forty-nine studies (1 randomized controlled trial, 9 prospective, and 39 retrospective case series) reported urodynamic data on 4930 neuro-urological patients. Of those, 2828 (98%) were spina bifida (SB) children. The total number of adults was 2044, mainly having spinal cord injury (SCI) (60%). A low bladder compliance was found in 568 (46.3%) and 341 (29.3%) of the paediatric and adult population, respectively. Hydronephrosis (HDN) was detected in 557 children (27.8%) in 19/28 studies and 178 adults (14.6%), mainly SCI, in 14/21 studies. Nine out of 30 multiple sclerosis (MS) patients affected by HDN (16.8%) showed low compliance in 4/14 studies.

CONCLUSIONS

Patients with SB and SCI have a higher risk of developing UUTD (mainly reported as HDN) compared to those with MS. Reduced compliance and high DLPP were major risk factors for UUTD. Although our findings clarify the mandatory role of urodynamics in the management of NLUTD, standardization and better implementation of assessments in daily practice may further improve outcomes of neuro-urological patients based on objective measurements, that is, urodynamics.

Outcome and complications of adjustable continence therapy (ProACT™) after radical prostatectomy: 10 years' experience in 143 patients

AIMS

To evaluate our outcomes of the adjustable continence balloons ProACT™ for the treatment of male stress urinary incontinence after radical prostatectomy.

METHODS

Between May 2007-August 2016 the ProACT™ was implanted in 143 patients without a history of radiotherapy. Endpoints were patient-reported changes in pad counts and complications. Treatment was considered successful if no pad or just one "security" pad per day sufficed, and improved if daily pad use was reduced by ≥50%.

RESULTS

Incontinence before implantation was mild in 36 (25%), moderate in 57 (40%), and severe in 50 (35%) patients. Complications within 30 days were classified by the Clavien-Dindo classification; eight (5.6%) grade I, three (2.1%) grade II, three (2.1%) grade IIIb, and 129 (90.2%) patients had no complication. Revision was done in 43 (30%) patients. The IPSS quality of life item improved significantly from 5.0 (IQR 4.0-5.0) preoperative to 2.0 (IQR 1.0-4.0) and 1.0 (IQR 0.0-3.0) 6 and 12 months after implantation, respectively. After a median follow up of 56 months (range 28 to 79, n = 112), 72 (64%) patients were improved, including 51 (45%) patients were successful. Daily pad use decreased from 3.0 to 1.0 (67% reduction). The median outcome on the Patient Global Impression of Improvement scale was "much better," and 97 (87%) patients perceived improvement.

CONCLUSIONS

The minimally invasive ProACT™ device showed a clear beneficial continence outcome in patients with stress urinary incontinence after radical prostatectomy. The majority of the patients were satisfied and perceived improvement ≥50% on daily pad use on the long term.

A Quality Assessment of Patient-Reported Outcome Measures for Sexual Function in Neurologic Patients Using the Consensus-based Standards for the Selection of Health Measurement Instruments Checklist: A Systematic Review

CONTEXT

Impaired sexual function has a significant effect on quality of life. Various patient-reported outcome measures (PROMs) are available to evaluate sexual function. The quality of the PROMs to be used for neurologic patients remains unknown.

OBJECTIVE

To systematically review which validated PROMs are available to evaluate sexual function in neurologic patients and to critically assess the quality of the validation studies and measurement properties for each identified PROM.

EVIDENCE ACQUISITION

A systematic review was performed according to the Preferred Reporting Items for Systematic Review and Meta-analysis statement. The included publications were assessed according to the Consensus-Based Standards for the Selection of Health Measurement Instruments checklist.

EVIDENCE SYNTHESIS

Twenty-one studies for PROMs regarding sexual function were identified for the following patient groups: spinal cord injury (11 studies), multiple sclerosis (MS; 6 studies), Parkinson's disease (2 studies), traumatic brain injury (1 study), and epilepsy (1 study). The evidence for the quality of PROMs was found to be variable, and overall evaluation of measurement properties was lacking in 71% of the studies. The measurement error and responsiveness were not studied in any of the publications.

CONCLUSIONS

Several PROMs have been identified to evaluate sexual function in neurologic patients. Strong evidence was found only for the Multiple Sclerosis Intimacy and Sexuality Questionnaire-15 and Multiple Sclerosis Intimacy and Sexuality Questionnaire-19 for patients with MS, although evidence was lacking for certain measurement properties as well. Future research should focus on identifying relevant PROMs and establishing adequate quality for all measurement properties in studies with high methodological quality.

PATIENT SUMMARY

A quality assessment of patient-reported outcome measures (PROMs) for sexual function in neurologic patients was made. The evidence found for good PROMs was limited. Studies with high methodological quality are needed to improve the quality of PROMs to evaluate sexual function in neurologic patients.

The validation of the Dutch SF-Qualiveen, a questionnaire on urinary-specific quality of life, in spinal cord injury patients

BACKGROUND

Optimizing the patients' quality of life is one of the main goals in the urological management of spinal cord injury (SCI) patients. In this study we validated the Dutch SF-Qualiveen, a short questionnaire that measures the urinary-specific quality of life, in SCI patients. No such measure is yet available for this patient group.

METHODS

In 2015-2016 SCI patients with urinary symptomatology who visited the outpatient clinics of Urology at the Erasmus Medical Centre and Rehabilitation at Rijndam Revalidation completed the SF-Qualiveen and UDI-6 during the visit and 1-2 weeks later. The UDI-6, a urinary tract symptom inventory, served as gold standard. Controls, recruited from the Otolaryngology outpatient clinic, completed the questionnaires once. Content-, construct-, and criterion validity and reliability (internal consistency and reproducibility) of the SF-Qualiveen were determined.

RESULTS

Fifty seven SCI patients and 50 controls were included. 12 SCI patients asserted that the SF-Qualiveen covered their bladder problems (good content validity). Patients' SF-Qualiveen scores being positively associated with severity of urinary symptoms and patients' scores being higher than those of controls indicated good construct validity. The positive association that was found between SF-Qualiveen and UDI-6 in patients (r = 0.66-0.67, P < 0.001) and controls (r = 0.63, P < 0.001) confirmed good criterion validity. Internal consistency (Cronbach's alpha 0.89-0.92) and reproducibility (intraclass correlation coefficient 0.94) of the SF-Qualiveen were good.

CONCLUSIONS

The Dutch SF-Qualiveen is a valid and reliable tool to measure the urinary-specific quality of life in SCI patients.

Heterogeneity in reporting on urinary outcome and cure after surgical interventions for stress urinary incontinence in adult neuro-urological patients: A systematic review

AIMS

To describe all outcome parameters and definitions of cure used to report on outcome of surgical interventions for stress urinary incontinence (SUI) in neuro-urological (NU) patients.

METHODS

This systematic review was performed and reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. The study protocol was registered and published (CRD42016033303; http://www.crd.york.ac.uk/PROSPERO). Medline, Embase, Cochrane controlled trials databases, and clinicaltrial.gov were systematically searched for relevant publications until February 2017.

RESULTS

A total of 3168 abstracts were screened. Seventeen studies reporting on SUI surgeries in NU patients were included. Sixteen different outcome parameters and nine definitions of cure were used. Six studies reported on objective outcome parameters mainly derived from urodynamic investigations. All studies reported on one or more subjective outcome parameters. Patient-reported pad use (reported during interview) was the most commonly used outcome parameter. Only three of 17 studies used standardized questionnaires (two on impact of incontinence and one on quality of life). Overall, a high risk of bias was found.

CONCLUSIONS

We found a considerable heterogeneity in outcome parameters and definitions of cure used to report on outcome of surgical interventions for SUI in NU patients. The results of this systematic review may begin the dialogue to a future consensus on this topic. Standardization of outcome parameters and definitions of cure would enable researchers and clinicians to consistently compare outcomes of different studies and therapies.

Real life persistence rate with antimuscarinic treatment in patients with idiopathic or neurogenic overactive bladder: a prospective cohort study with solifenacin

Background

Several studies have shown that the antimuscarinic treatment of overactive bladder is characterized by low long-term persistence rates. We have investigated the persistence of solifenacin in real life by means of telephonic interviews in a prospective cohort. We included both patients with idiopathic overactive bladder as well as neurogenic overactive bladder.

Methods

From June 2009 until July 2012 patients with idiopathic or neurogenic overactive bladder who were newly prescribed solifenacin were included. In total 123 subjects were followed prospectively during one year by means of four telephonic interviews, which included questions about medication use and adverse events.

Results

After one year 40% of all patients included was still using solifenacin, 50% discontinued and 10% was lost to follow-up. In the neurogenic group 58% was still using solifenacin versus 32% in the idiopathic group after one year (p < 0,05). The main reasons to stop solifenacin were lack of efficacy, side effects and a combination of both.

Conclusions

This prospective cohort study showed a real life continuation rate of 40% after 12 months. This continuation rate is higher than found in most other studies.

The use of regular telephonic evaluation might have improved medication persistence. The findings of this study also suggest that patients with neurogenic overactive bladder have a better persistence with this method of evaluation compared to patients with idiopathic overactive bladder.

Trial registration

This study was retrospectively registered on march 17, 2017 at the ISRCTN registry with study ID ISRCTN13129226.

Long-term effectiveness and complication rates of bladder augmentation in patients with neurogenic bladder dysfunction: A systematic review

AIMS

To systematically evaluate effectiveness and safety of bladder augmentation for adult neuro-urological patients.

METHODS

The Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) statement was followed for review of publications. The Medline, Embase, and Cochrane controlled trial databases and clinicaltrial.gov were searched until January 2015. No limitations were placed on date or language. Non-original articles, conference abstracts, and publications involving children and animals were excluded. Risk-of-bias and confounder assessment was performed.

RESULTS

A total of 20 studies including 511 patients were eligible for inclusion. The level of evidence for the included studies was low, most level 4 studies with only one level 3 study. The data were narratively synthesized. Across all studies high risk-of bias and confounding was found. Primary outcomes were assessed in 16 of the 20 studies and showed improved quality of life and anatomical changes as well as stable renal function. The secondary outcomes were reported in 17 of the 20 studies and urodynamic parameters and continence all demonstrated improvement after bladder reconstruction. Long-term complications continued up to 10 years post-operatively, including bowel dysfunction in 15% of the patients, stone formation in 10%, five bladder perforations and one bladder cancer.

CONCLUSIONS

Available studies are not plentiful and of relatively poor quality, appropriately designed prospective studies are urgently needed. Despite this, bladder augmentation appears to be a highly effective procedure at protecting the upper urinary tract and improving quality of life. However, it is associated with relatively high morbidity in both the short and long term.

Continent catheterizable tubes/stomas in adult neuro-urological patients: A systematic review

AIMS

To systematically review all available evidence on the effectiveness and complications of continent cutaneous stoma or tube (CCS/T) to treat bladder-emptying difficulties in adult neuro-urological patients.

METHODS

The search strategy and studies selection were performed on Medline, Embase, and Cochrane using the PICOS method according to the PRISMA statement (CRD42015019212; http://www.crd.york.ac.uk/PROSPERO).

RESULTS

After screening 3,634 abstracts, 11 studies (all retrospective, enrolling 213 patients) were included in a narrative synthesis. Mean follow-up ranged from 21.6 months to 8.7 years (median: 36 months, IQR 28.5-44). At last follow-up, the ability to catheterize rate was ≥84% (except in one study: 58.3%) and the continence rate at stoma was >75%. Data comparing health-related quality-of-life before and after surgery were not available in any study. Overall, 85/213 postoperative events required reoperation: 7 events (7 patients) occurring ≤3 months postoperatively, 22 events (16 patients) >3 months, and 56 events (55 patients) for which the time after surgery was not specified. Sixty additional complications (60 patients) were reported but did not require surgical treatment. Tube stenosis occurred in 4-32% of the cases (median: 14%, IQR 9-24). Complications related to concomitant procedures (augmentation cystoplasty, pouch) included neovesicocutaneous fistulae, bladder stones, and bladder perforations. Risk of bias and confounding was high in all studies.

CONCLUSIONS

CCS/T appears to be an effective treatment option in adult neuro-urological patients unable to perform intermittent self-catheterization through the urethra. However, the complication rate is meaningful and the quality of evidence is low, especially in terms of long-term outcomes including the impact on the quality-of-life.

Maximum Urethral Closure Pressure Increases After Successful Adjustable Continence Therapy (ProACT) for Stress Urinary Incontinence After Radical Prostatectomy

OBJECTIVE

To evaluate changes of the urethral pressure profile (UPP) after implantation of adjustable continence therapy (ProACT), a minimally invasive procedure in which 2 volume-adjustable balloons are placed periurethrally for treatment of male stress urinary incontinence. The working mechanism of the ProACT to achieve continence has not been fully understood. We hypothesized that successful treatment with ProACT improves urinary continence by inducing a significant increase in static urethral pressure.

MATERIALS AND METHODS

We included patients who underwent UPP before and after ProACT implantation. UPPs were initially performed with the Brown-Wickham water perfusion method and later with the T-DOC Air-Charged catheter method. Pre- and postoperative UPPs and International Prostate Symptom Scores were evaluated. UPP measurements of successfully (no or 1 precautionary pad per day) and unsuccessfully treated patients were compared.

RESULTS

Twenty-seven patients were included in the study; 23 patients were successfully and 4 patients were unsuccessfully treated. Maximum urethral closure pressure (MUCP) increased significantly from median 58.0 to 79.0 cmH2O in the successfully treated group (P = .001). Within the subgroup of unsuccessfully treated patients, MUCP did not change significantly (P = .715). The change in MUCP was statistically significantly different between the successful and unsuccessful group (P = .034). Total score of the International Prostate Symptom Scores did not change significantly after ProACT implantation (P = .097).

CONCLUSION

Successful treatment with ProACT is associated with a significant increase of MUCP. This implies that increased static urethral pressure contributes to the working mechanism of the ProACT device to achieve continence.

Intermittent sacral neuromodulation for idiopathic urgency urinary incontinence in women

AIMS

SNM has been proven to be effective in the treatment of refractory UUI. Total costs and patient burden due to regular battery changes may prevent broad implementation of this treatment. The aim was to achieve a minimal improvement of 50% in incontinence episodes compared to pre-SNM by using iSNM.

METHODS

This prospective cohort study was performed in women with UUI receiving treatment with SNM for a minimum of 6 months. The neurostimulator was programmed to 8 hr "on" and 16 hr "off" per day for 12 weeks. Prior to iSNM, data were collected during no SNM and cSNM. Bladder diaries and various patient reported outcome measures were collected at predetermined time points: 1-5 weeks, and 8, 12, and 16 weeks. Nonparametric tests were used for the statistical analysis.

RESULTS

Of the 19 patients 63% showed an improvement of >50% of incontinence episodes during iSNM compared to pre-SNM. Bladder diary parameters showed a difference between pre-SNM and iSNM median (P-value); incontinence episodes/24 hr, 4.1-1.0 (P = 0.04), incontinence severity, 2.0-1.0 (P = 0.001), voiding episodes/24 hr, 13.0-8.0 (P = 0.001), and voided volume, 149-219 ml (P = 0.04). The UDI-6, 50.0-27.8 (P = 0.03), and the IIQ-7 scores, 50.0-9.5 (P = 0.04) also showed a significant improvement. No difference was demonstrated between iSNM and cSNM.

CONCLUSIONS

Compared to pre-SNM parameters, iSNM shows an improvement in both objective and subjective outcomes. Specifically no difference was found between iSNM and cSNM, indicating that iSNM could be a feasible and cost-effective alternative. Neurourol.

Validation of a Dutch version of the Actionable 8-item screening questionnaire for neurogenic bladder overactivity in multiple sclerosis: an observational web-based study

Background

In patients with multiple sclerosis (MS) the impact of urological symptoms on quality of life and daily activities is considerable. Yet, a substantial percentage of patients may not be urologically evaluated and thus fail to be treated concordantly. The 8-item Actionable questionnaire is a validated English screening tool for the detection of neurogenic bladder overactivity in MS. To enable the use of the 8-item Actionable in The Netherlands and Belgium we translated the questionnaire into the Dutch language and investigated the test-retest reliability and the concurrent validity of the Dutch version.

Methods

The process of translating the English Actionable questionnaire into the Dutch language included forward translations and back-translations. Then, in an online observational study, MS patients completed the Dutch Actionable at Days 1 and 8, and the Multiple Sclerosis Quality of Life 54-Items (MSQoL-54) and Multiple Sclerosis Impact Profile (MSIP) questionnaires at Day 1; the Expanded Disability Status Scale (EDSS) score was assessed by phone at Day 1. For assessment of the test-retest reliability Pearson’s correlation coefficient (r) between the Day 1 and Day 8 Actionable scores was calculated. For assessment of the concurrent validity r values were calculated between the Day 1 Actionable score and the EDSS score, the Physical and Mental MSQoL-54 composites, and the MSIP domain and symptom disability scores.

Results

Study population: N = 141 (106 female, 35 male) (80 relapsing remitting, 48 progressive, 13 unknown), mean age 47.8 (standard deviation [SD] 10.4) years, mean EDSS score 4.7 (SD 1.8); 137 patients completed the Day 8 assessment. Pearson’s r between Actionable scores Day 1 and Day 8: 0.85 (P < .0001). Pearson’s r between Actionable score Day 1 and scores for EDSS 0.41 (P < 0.0001), MSQoL-54 Physical −0.31 (P = 0.0002), MSQoL-54 Mental −0.29 (P = 0.0005), MSIP Excretion and Reproductive Functions 0.44 (P < 0.0001), Muscle and Movement Functions 0.39 (P < .0001), Basic Movement Activities 0.37 (P < 0.0001), Activities of Daily Living 0.32 (P < 0.0001), Participation in Life Situations 0.29 (P = 0.0006) and Mental Functions 0.20 (P = 0.0189).

Conclusions

The Dutch version of the Actionable urological screening tool for MS shows a good test-retest reliability and a good concurrent validity with disabilities and HRQoL.

The Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ-12): validation of the Dutch version

Objectives and hypothesis

To establish the reliability and validity of the Dutch version of the Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ-12) in women with pelvic floor dysfunction.

Methods

The PISQ-12 was translated into Dutch following a standardized translation process. A group of 124 women involved in a heterosexual relationship who had had symptoms of urinary incontinence, fecal incontinence and/or pelvic organ prolapse for at least 3 months were eligible for inclusion. A reference group was used for assessment of discriminative ability. Data were analyzed for internal consistency, reproducibility, construct validity, responsiveness, and interpretability. An alteration was made to item 12 and was corrected for during the analysis.

Results

The patient group comprised 70 of the 124 eligible women, and the reference group comprised 208 women from a panel representative of the Dutch female population. The Dutch PISQ-12 showed an adequate internal consistency with a Cronbach’s alpha of 0.57 – 0.69, increasing with correction for item 12 to 0.69 – 0.75, for the reference and patient group, respectively. Scores in the patient group were lower (32.6 ± 6.9) than in the reference group (36.3 ± 4.8; p = 0.0001), indicating a lower sexual function in the patient group and good discriminative ability. Reproducibility was excellent with an intraclass correlation coefficient for agreement of 0.93 (0.88 – 0.96). A positive correlation was found with the Short Form-12 Health Survey (SF-12) measure representing good criterion validity. Due to the small number of patients who had received treatment at the 6-month follow-up, no significant responsiveness could be established.

Conclusions

This study showed that the Dutch version of the PISQ-12 has good validity and reliability. The PISQ-12 will enable Dutch physicians to evaluate sexual dysfunction in women with pelvic floor disorders.

Supraspinal Control of Urine Storage and Micturition in Men--An fMRI Study

Despite the crucial role of the brain in the control of the human lower urinary tract, little is known about the supraspinal mechanisms regulating micturition. To investigate the central regulatory mechanisms activated during micturition initiation and actual micturition, we used an alternating sequence of micturition imitation/imagination, micturition initiation, and actual micturition in 22 healthy males undergoing functional magnetic resonance imaging. Subjects able to micturate (voiders) showed the most prominent supraspinal activity during the final phase of micturition initiation whereas actual micturition was associated with significantly less such activity. Initiation of micturition in voiders induced significant activity in the brainstem (periaqueductal gray, pons), insula, thalamus, prefrontal cortex, parietal operculum and cingulate cortex with significant functional connectivity between the forebrain and parietal operculum. Subjects unable to micturate (nonvoiders) showed less robust activation during initiation of micturition, with activity in the forebrain and brainstem particularly lacking. Our findings suggest that micturition is controlled by a specific supraspinal network which is essential for the voluntary initiation of micturition. Once this network triggers the bulbospinal micturition reflex via brainstem centers, micturition continues automatically without further supraspinal input. Unsuccessful micturition is characterized by a failure to activate the periaqueductal gray and pons during initiation.

Sacral neuromodulation as treatment for refractory idiopathic urge urinary incontinence: 5-year results of a longitudinal study in 60 women

PURPOSE

We evaluated the results of sacral neuromodulation after 5-year followup in women with refractory idiopathic urge urinary incontinence.

MATERIALS AND METHODS

A neuromodulation system with an original (nontined) lead was implanted by open surgery after a positive percutaneous nerve evaluation in 60 women from 1990 to 2004. Voiding incontinence diary parameters were used to evaluate efficacy. Success was defined as at least a 50% decrease in the number of incontinence episodes or pads used daily. Safety was also evaluated.

RESULTS

The success rate gradually decreased from 52 patients (87%) at 1 month to 37 (62%) at 5 years. Complete continence persisted in 15% of patients. The system was still used by 80% of patients at 5 years. In 32 patients a total of 57 adverse events occurred, which were not severe (Clavien grade I and IIIb in 61% and 39%, respectively).

CONCLUSIONS

Sacral neuromodulation appears to be a safe technique for refractory idiopathic urge urinary incontinence in women. The success rate gradually decreased to 62% after 5 years with 15% of patients completely continent.

Surgery for stress urinary incontinence in women: A 2006 review

The surgical treatment of female stress urinary incontinence is a rapidly changing field. This review discusses recent advances in various injectables, minimally invasive techniques and open procedures. It particularly evaluates data from long-term outcome studies and describes peri- and postoperative complications from several procedures, such as bulking agents, tension-free vaginal tape and its modifications (TOT, TVT-O) as well as open and laparoscopic colposuspension.
