Is the Standard Artificial Urinary Sphincter AMS 800 Still a Treatment Option for the Irradiated Male Patient Presenting with a Devastated Bladder Outlet?

BACKGROUND

Circular urethral compression with an artificial sphincter allows control of voiding, even in patients with severe stress urinary incontinence, but it heightens the risk of urethral atrophy and erosion. This study of one of the largest populations of patients treated with radiotherapy investigates the additive effect of the post-radiogenic stricture of the membranous urethra/bladder neck on AMS 800 artificial urinary sphincter outcomes.

METHODS

In a retrospective multicenter cohort study, we analyzed patients fitted with an AMS 800, comparing those who had received radiotherapy with patients presenting a devastated bladder outlet (stricture of the membranous urethra/bladder neck). We determined the correlation between these groups of patients using both univariate and stepwise adjusted multivariate regression. The revision-free interval was estimated by a Kaplan-Meier plot and compared by applying the log-rank test. A p value below 0.05 was considered statistically significant.

RESULTS

Of the 123 irradiated patients we identified, 62 (50.4%) had undergone at least one prior desobstruction for bladder-neck/urethra stenosis. After a mean follow-up of 21 months, the latter tended to achieve social continence less frequently (25.7% vs. 35%; p = 0.08). Revision was required significantly more often for this group (43.1% vs. 26.3%; p = 0.05) due to urethral erosion in 18 of 25 cases. A stenosis recurred in five cases; desobstruction was performed in two cases, leading to erosion in both. Multivariate analysis revealed a significantly higher risk of revision when recurrent stenosis necessitated at least two prior desobstructions (HR 2.8; p = 0.003).

CONCLUSIONS

A devastated bladder outlet is associated with a lower proportion of men with social continence and a significantly higher need for revision compared with irradiated patients without a history of urethral stenosis. Alternative surgical procedures should be discussed beforehand, especially in cases of recurrent urethral stenosis.

Listening to Music during Outpatient Cystoscopy Reduces Pain and Anxiety and Increases Satisfaction: Results from a Prospective Randomized Study

BACKGROUND

This study investigates the effect of classical music, music of patients' own choice, or no music on pain reduction during elective cystoscopy.

OBJECTIVES

The aim of the study was to describe the effect of listening to classical music, music of patients' own choice, or no music on patient's pain and satisfaction rates when carrying out an elective cystoscopy and the effect on the assessment capability of the performing urologist.

DESIGN, SETTING, AND PARTICIPANTS

This randomized trial included 127 patients undergoing elective cystoscopy at the Urological Department of the University Clinic of Munich between June 2019 and March 2020. Outcome Measurements and Statistical Analysis: Patients were assigned randomly to 3 groups: group I: listening to standardized classical music (n = 35), group II: listening to music according to the patients' choice (n = 34), and control group III: no music (n = 44). Prior to cystoscopy, anxiety levels were assessed by the Beck Anxiety Inventory (BAI). The Visual Analog Scale (VAS, range 1-100) was used for a self-assessment of pain, discomfort, and satisfaction. Statistical analysis was done with Spearman's rank correlation and t-tests.

RESULTS AND LIMITATIONS

The median age was 63 (range 27-91) years. The duration of cystoscopy was 5.7 (1-30) min. Patients had undergone a median of 2.3 cystoscopies in the past. Between giving informed consent and cystoscopy, patients had to wait for a median of 64 (0-260) min. The median VAS pain score was significantly lower in group I at 1.7 and group II at 2.3 versus 5.2 in the control group III (p < 0.001). The control group III had significantly worse pain and patient satisfaction rates compared with groups I and II. Group I had a significant lower VAS pain score than groups II and III (p < 0.001). Classical music also increased the assessment capability of the preforming urologist.

CONCLUSIONS

Listening to music during elective cystoscopy significantly reduces pain and distress and leads to higher patient and surgeon satisfaction. We recommend listening to classical music or music chosen by the patients during outpatient flexible/rigid cystoscopy in daily clinical routine. Patient Summary: In this study, we found that patients who listened to classical music or music of their own choice while undergoing a cystoscopy showed significant reduction of pain and distress.

How the COVID-19 Pandemic Affects Sexual Behavior of Hetero-, Homo-, and Bisexual Males in Germany

Introduction

The COVID-19 pandemic drastically altered the way of life around the world. Due to social distancing measures, contact restrictions and fears of infection, social life has changed significantly. These measures along with the stressors associated with the current worldwide situation, will inevitably have an effect on people's interpersonal and personal behaviors.

Aim

This study evaluates the effect the COVID-19 pandemic and nationwide German lockdown had on the sexual behavior of cis men.

Methods

An anonymous nationwide web-based questionnaire was conducted among cis men in Germany during the first COVID-19 home isolation (April 20, 2020–July 20, 2020). The questionnaire was distributed via e-mail, online chats and social-media platforms.

Main Outcome Measures

Data was collected on general characteristics including demographics and socio-economic backgrounds. To evaluate sexual health, questions from the Sexual Behavior Questionnaire were included.

Results

523 cis male participated. 414 met the inclusion criteria. Most were heterosexual (n = 248, 59.9%; vs homosexual n = 97, 23.4%; vs bisexual n = 69, 16.7%). 243 (59%) were employed, 153 (37.1%) were students and 16 (3.9%) were unemployed. Most of the participants reported an annual income lower than 75.000€. During the lockdown, average weekly frequency of sexual intercourse and masturbation was increased in all groups. Consistently, a significant rise of higher satisfaction with the frequency of sexual contacts during the quarantine was observed (P < .05). Furthermore, the level of sexual arousal increased significantly in all groups (P < .0005). Capability to enjoy sexual intercourse or masturbation increased significantly in heterosexual (P < .0005) and homosexual men (P < .005). Bisexual participants showed a significant increase in general satisfaction with sexual life (P < .05) and a significant decrease in satisfaction in relationship or single life (P < .05). Positive confounders in the changing of sexual behavior during the COVID-19 pandemic were: Being in a relationship or being single, parenthood and being employed.

Conclusion

Our study firstly describes how COVID-19 pandemic related restrictions and social distancing measurements altered sexual behavior amongst cis male in Germany. Further studies, including sexual minorities specifically, are needed to clarify if the behavior in the first German nationwide quarantine has persisted or transformed as the pandemic proceeded.

Age at surgery is not a prognostic factor for the AdVance-XP male sling efficacy: A post-hoc analysis of a prospective 7-year multicentric study

OBJECTIVE

To evaluate the factor age at the surgery on long-term postoperative outcomes in patients with postprostatectomy incontinence (PPI) after AdVance XP transobturator male sling implantation.

METHODS

A total of 115 male patients with PPI, who had undergone AdVance XP sling implantation, were included. Patients had PPI with endoscopically confirmed good sphincteric-contractility and a positive coaptive response. Kruskal-Wallis test with Dunn post-hoc tests were used to analyze the postoperative outcome differences between the patient groups aged less than 66, 66-75, and over greater than 75 years. Outcome measures were the 24 h pad test, the number of daily pads used, the International Consultation on Incontinence Questionnaire short form (ICIQ-SF), International Quality of Life Score (IQOL), Patient Global Impression of Improvement (PGI-I), International Index of Erectile Function-5 (IIEF-5), International Prostate Symptom Score (IPSS), and Visual Analog Scale scores. Observation time points were 3, 6, 12, 24, 36, 48, 60, and 84 months after surgery.

RESULTS

Between the age groups, there was no difference in the success rate of the procedure (defined as 0 pads/24 h and less than 5 g in the 24-h pad test) at any point in time. Subjective parameters measures using the ICIQ-SF, PGI-I, IQOL, and IPSS scores showed no differences between the two cohorts. Only erectile function (IIEF-5 score) was lower in older patients in comparison to the cohort aged less than 66 years (p < 0.05 at 3, 6, 12, 24, 36, and 48 months).

CONCLUSIONS

The present study complements the European multicentre AdVance XP follow-up study. Here, we show that age at surgery does not affect the objective success, subjective success, or the complication rate. Thus, we do not recommend factoring in chronological age into surgical selection criteria for the AdVance XP implantation.

Mapping Telemedicine in German Private Practice Urological Care: Implications for Transitioning beyond the COVID-19 Pandemic

Background

There are limited data on the use and concern of telemedicine among German urologists, and thus, there are no established guidelines for telemedical diagnosis, treatment, and prevention of urological indications.

Methods

An anonymized survey was conducted among German private practice urologists during the 2019 coronavirus disease (COVID-19) pandemic. The χ² test, Mann-Whitney U-test, and Kruskal-Wallis test were used for statistical analysis.

Results

257 urologists were included in the final analysis. Thirty-five (14.0%) of urologists had used telemedicine as part of their consultation, and 221 (86.0%) had not used telemedicine. There was no difference between telemedicine adoption rates between rural and urban settings. Telemedicine users were significantly more satisfied with the information they had received regarding telemedicine issues. Users saw the greatest barrier to telemedicine that patients do not take up the offer of telemedicine. Nonusers were most concerned with unclear indications for telemedicine followed by lesser reimbursements during telemedicine than in-person visitations. Users were significantly more likely to use telemedicine beyond the COVID-19 pandemic. Urologists, who wanted to use the service in the future, wanted an active support by the German society of urology and guidelines for telemedicine. Last, users and nonusers preferred telemedicine for non-acute chronic diseases and follow-up visitations.

Conclusion

Despite the COVID-19 pandemic, telemedicine remains a rarely used service among German private practice urologists. Ultimately, to overcome the current challenges, urologists require an active support for the service through the German Society of Urology and telemedical guidelines.

Five-Year Results of a Prospective Multicenter Trial: AdVance XP for Postprostatectomy-Incontinence in Patients with Favorable Prognostic Factors

OBJECTIVE

The aim of this study was to assess the security, value, and efficacy of the second-generation AdVance male sling XP (Boston Scientific®), after implementation in 2010 with advantageous modifications in the sling structure and needle shape, in a prospective multicenter long-term follow-up study.

METHODS

In total, 115 patients were included. Exclusion criteria were earlier incontinence (UI) surgery, nocturnal UI, former radiotherapy, or night-time incontinence. We also excluded patients with a functional urethra <1 cm in a preoperatively performed repositioning test. A consistent 24-h pad test, International Quality of Life (IQOL) score, visual analog pain scale (VAS), International Consultation-Incontinence Questionnaire (ICIQ-UI SF), International Index of Erectile Function (IIEF-5), International Prostate Symptom Score (IPSS), and Patient Global Impression of Improvement (PGI-I) scores were requested postoperatively.

RESULTS

The 24-month follow-up (114 patients) revealed 64.0% cured and 28.8% improved patients. Mean urine loss was reduced significantly to 19.0 g (p < 0.001). A mean PGI score of 1.5 and a mean VAS score of 0.2 were obtained. The 60-month follow-up (59 patients) revealed 57.6% cured and 25.4% improved patients. Mean urine loss was reduced significantly to 18.3 g (p < 0.001). A mean PGI score of 1.6 and a mean VAS score of 0.2 were obtained.

CONCLUSIONS

The AdVance XP displays excellent continence results and secure effectiveness over a 5-year period. Moreover, these data are demonstrating low complication rates and improved quality of life in the long-term use of AdVance XP.

[Incontinence surgery-quality criteria and structured follow-up]

The following article summarizes the current evidence including postoperative success rates and complications for various surgical options in the treatment of urinary incontinence. Due to different inclusion criteria and inconsistent definitions of study endpoints, the analysis of available studies is difficult. Thus, comparative studies with new devices for established treatment options should be planned. Structured processes used in certified continence centers improve the quality of care. Furthermore by documenting relevant complications, comparisons of treatment results thus become possible and provide evidence for the use of different surgical options in the treatment of urinary incontinence.

[Digital innovation in medicine: the COVID-19 pandemic as an accelerator of "digital health"]

The COVID-19 pandemic has triggered a wave of digitalization in medicine. In the coming years, the use of state-of-the-art technologies will revolutionize routine diagnostic and treatment approaches, as well as have a positive effect on the physician-patient relationship. The application of AI (artificial intelligence) and Big Data, combined with the development of mHealth (mobile health), represents the most significant milestone in the creation of a digital and intelligent health system!

Impact of antiangiogenic treatment on the erectile function in patients with advanced renal cell carcinoma

We longitudinally assessed erectile function as well as the willingness to use pro-erectile treatment in a cohort on AAT for advanced RCC. Thirty-seven patients with advanced RCC completed the five-item version of the International Index of Erectile Function (IIEF-5) and other interview items before (T0) and 12 weeks into therapy (T12) with AAT. Patients were further asked if they were willing to use and pay out-of-pocket for on-demand treatment with phosphodiesterase-5-inhibitors (PDE-5i). Statistical analysis was performed using nonparametric hypothesis testing. The IIEF-5 score at T12 was significantly decreased compared with T0 (p < .001). Subjective patient satisfaction regarding their sexual lives was associated with higher IIEF-5 scores at both time points (p = .006 and p = .03, respectively). At T12, subjective sexual contentment showed a nonsignificant trend towards decline (p = .074). Patients who opted for medical treatment of ED showed significantly better IIEF-5 scores at both time points compared with the rest of the cohort (p < .001 and p = .005, respectively). In summary, AAT seems to have a negative effect on erectile function in RCC patients, however, the role of psychosocial issues warrants further elucidation. Affected patients may benefit from a proactive approach promoting medical treatment of erectile dysfunction during AAT.

Patient Selection in Surgical Centers of Expertise in the Treatment of Patients with Moderate to Severe Male Urinary Stress Incontinence

<b><i>Objective:</i></b> To analyze decision-making in patients with male urinary incontinence (SUI) in centers of expertise. The artificial urinary sphincter (AUS) remains the gold standard for male patients with moderate to severe SUI but adjustable male slings are a minimally invasive treatment option with good results, hence without a high level of evidence regarding the optimal patient selection. <b><i>Materials and Methods:</i></b> In total, 220 patients (88 AUS; 132 adjustable slings) were investigated from the DOMINO database that underwent surgery between 2010 and 2012 in 5 urological departments that offer adjustable sling systems as well as AUS systems for patients with moderate to severe urinary incontinence. For statistical analysis, the Mann-Whitney <i>U</i> test was used to identify differences between both groups. <b><i>Results:</i></b> Patients selected for an adjustable male sling were less likely to have a neurological disease (5.3 vs. 9.1%; <i>p</i> = 0.030), a prior urethral stricture (22.7 vs. 50.0%; <i>p</i> = 0.001), a prior incontinence surgery (24.4 vs. 45.5%; <i>p</i> = 0.01), or a prior radiation therapy (26.5 vs. 40.1%; <i>p</i> = 0.001). The severity of preoperative incontinence was higher in patients selected for an AUS with a mean pad usage per day of 7.60 versus 5.80 (<i>p</i> &#x3c; 0.001). Mean postoperative pad usage and patients’ subjective perception were comparable in both groups. <b><i>Conclusion:</i></b> In centers offering both options, the decision-making is mainly based upon presence of radiation therapy and previous failed incontinence surgery. Despite the more complex patient cohort selected for an AUS implantation with a possible impact on the postoperative outcome, the functional results seem to be comparable indicating a proper preoperative patient assessment and selection in this cohort.

High/low-volume center experience predicts outcome of AMS 800 in male stress incontinence: Results of a large middle European multicenter case series

AIM

To analyze the influence of implantation volume of artificial sphincters (AMS 800) on outcome in a large central European multicenter cohort study.

METHODS

As part of the DOMINO (Debates on Male Incontinence) project, the surgical procedures and outcomes were retrospectively analyzed in a total of 473 patients who received an artificial sphincter (AMS 800) between 2010 and 2012. Clinics that implanted at least 10 AMS 800 per year were defined as high-volume centers.

RESULTS

Sixteen centers had a mean rate of 9.54 AMS 800/y of which five clinics were identified as high-volume centers. They implanted significantly more double cuffs (55% vs 12.1%; P < .001), used the perineal approach significantly more often (78% vs 67.7%; P = .003) and chose larger mean cuff sizes (4.63 cm vs 4.42 cm; P = .002). With a mean follow-up of 18 months, the revision rate was significantly higher at low-volume centers (38.5% vs 26.7%; P = .037), urethral erosion being the main reason for revision. Social continence (0-1 pads/24 h) was achieved significantly more often in high-volume centers (45.5% vs 24.2%; P = .002).

CONCLUSIONS

Our study showed significantly better continence results and lower revision rates at high-volume centers, confirming earlier results that are still true in this decade. We, therefore, recommend surgery for male incontinence at qualified centers.

Secondary Sling Implantation after Failure of Primary Surgical Treatment for Male Stress Urinary Incontinence: A Retrospective Study

OBJECTIVE

The artificial urinary sphincter (AUS) is the surgical gold standard after previously failed surgical treatment for male urinary stress incontinence. The evidence for a male sling as salvage treatment is poor, but there is a proportion of patients that refuse implantation of an AUS or have a relative contraindication. The goal of our retrospective study was an analysis of outcome and complications of patients with a secondary sling after previously failed surgery for stress urinary incontinence (SUI).

MATERIALS AND METHODS

Data on 186 patients who had a prior incontinence surgery were extracted from the DOMINO database. 139 patients (74.7%) received an AUS and 41 patients (22.0%) who had received a secondary sling system between 2010 and 2012 after previously failed surgery for male urinary incontinence could be identified and were further analyzed.

RESULTS

Eight patients (19.5%) received a secondary repositioning sling and 33 patients (80.5%) received a secondary adjustable sling system. A prior surgery for urethral stricture was performed in 4 patients (9.8%). No major intraoperative complications were reported. A simultaneous explantation was performed in 12 patients (29.3%). The mean number of pad reductions was 4.93 (p = 0.026). No intraoperative complications and no postoperative surgical revisions were reported. The mean follow-up of the patient cohort with a secondary sling was 16 months.

CONCLUSION

We provide the largest cohort of male patients up to date with a secondary sling after primary failure of surgery for male SUI. Although the procedure is a rarely performed surgery and without a high level of evidence, a secondary adjustable male sling system might be a feasible option in selected patients with acceptable complication rates, whereas a valuable outcome regarding continence rates cannot be sufficiently supplied by our data.

Fixed or adjustable sling in the treatment of male stress urinary incontinence: results from a large cohort study

Background

Fixed and adjustable male slings for the treatment of male urinary stress incontinence became increasingly popular during the last decade. Although fixed slings are recommended for the treatment of mild to moderate stress urinary incontinence, there is still a lack of evidence regarding the precise indication for an adjustable male sling. Furthermore, there is still no evidence that one type of male sling is superior to another. However, both, adjustable and fixed slings, are commonly utilized in daily clinical practice. This current investigation aims to evaluate the differences between fixed and adjustable male slings regarding indications, complication rates and functional outcome in the treatment of male stress urinary incontinence in current clinical practice.

Methods

A total of 294 patients with a fixed and 176 patients with an adjustable male sling were evaluated in a multicenter single arm cohort trial. Data collection was performed retrospectively according the medical record. Functional outcome was prospectively analyzed by standardized, validated questionnaires. Descriptive statistics was performed to present patient characteristics, complication rates and functional outcome. A chi2-test for categorical and independent t-test for continuous variables was performed to identify heterogeneity between the groups and to correlate preoperative characteristics with the outcome. A P value <0.05 was considered statistically significant.

Results

Patients with higher degree of urinary incontinence (P<0.001) and risk factors such as history of pelvic irradiation (P<0.001) or prior surgery for urethral stricture (P=0.032) were more likely to receive an adjustable MS. Complication rates were comparable except for infection (P=0.009, 0 vs. 2.3%) and pain (P=0.001, 1.7% vs. 11.3%) which occurred more frequently in adjustable slings. Functional outcome according validated questionnaires demonstrated no differences between fixed and adjustable male slings.

Conclusions

Adjustable male slings are more frequently utilized in patients with higher degree of incontinence and risk factors compared to fixed slings. No differences could be identified between functional outcome which may imply an advantage for adjustability. However, pain and infection rates were significantly higher in adjustable MS and should be considered in the decision process for sling type.

The impact of perioperative complications on favorable outcomes after artificial urinary sphincter implantation for post-prostatectomy incontinence

Objective

To investigate the effect of perioperative complications involving artificial urinary sphincter (AUS) implantation on rates of explantation and continence as well as health-related quality of life (HRQOL).

Materials and methods

Inclusion criteria encompassed non-neurogenic, moderate-to-severe stress urinary incontinence (SUI) post radical prostatectomy and primary implantation of an AUS performed by a high-volume surgeon (>100 previous implantations). Reporting complications followed the validated Clavien-Dindo scale and Martin criteria. HRQOL was assessed by the validated IQOL score, continence by the validated ICIQ-SF score. Statistical analysis included Chi (2) test, Mann-Whitney-U test, and multivariate regression models (p <0.05).

Results

105 patients from 5 centers met the inclusion criteria. After a median follow-up of 38 months, explantation rates were 27.6% with a continence rate of 48.4%. In the age-adjusted multivariate analysis, perioperative urinary tract infection was confirmed as an independent predictor of postoperative explantation rates [OR 24.28, 95% CI 2.81-209.77, p=0.004). Salvage implantation (OR 0.114, 95% CI 0.02-0.67, p=0.016) and non-prostatectomy related incontinence (OR 0.104, 95% CI 0.02-0.74, p=0.023) were independent predictors for worse continence outcomes. Low visual analogue scale scores (OR 9.999, 95% CI 1,42-70.25, p=0.021) and ICIQ-SF scores, respectively (OR 0.674, 95% CI 0.51-0.88, p=0.004) were independent predictors for increased HRQOL outcomes. Perioperative complications did not significantly impact on continence and HRQOL outcomes.

Conclusion

Findings show postoperative infections adversely affect device survival after AUS implantation. However, if explantation can be avoided, the comparative long-term functional results and HRQOL outcomes are similar between patients with or without perioperative complications.

[Use of synthetic slings and mesh implants in the treatment of female stress urinary incontinence and prolapse : Statement of the Working Group on Urological Functional Diagnostics and Female Urology of the Academy of the German Society of Urology]

Due to a safety alert issued by the US Food and Drug Administration (FDA) in 2011 for transvaginal mesh implants to treat female prolapse as a result of numerous reports of complications such as infection, chronic pain, dyspareunia, vaginal erosion, shrinkage and erosion into other organs nearly all industrial products have been withdrawn from the market in the meantime. The United Kingdom, Australia, and New Zealand extended warnings and prohibitions even on the implantation of midurethral slings (TVT, TOT). In view of these current international controversies regarding the use of implanted materials for the treatment of stress incontinence and prolapse and the lack of clear guidelines for the use of biomaterials, the opinion of the Working Group on Urological Functional Diagnostics and Female Urology should provide clarity. The Opinion is based on the SCENIHR Report of the "European Commission's Scientific Committee on Emerging and Newly Identified Health Risks", the "Consensus Statement of the European Urology Association and the European Urogynaecological Association on the Use of Implanted Materials for Treating Pelvic Organ Prolapse and Stress Urinary Incontinence" and in compliance with relevant EAU and national guidelines and the opinion of the Association for Urogynaecology and Plastic Pelvic Floor Reconstruction (AGUB eV). In addition, recommendations are given for the future handling of implants of slings and meshes for the treatment of stress incontinence and prolapse from a urologic viewpoint.

Effects of Headache on CNS Vital Signs Performance in a Concussed Community Sample

Purpose

Headache (HA) is the most common symptom following concussion. We examined the effect of HA on CNS Vital Signs (CNSVS) performance.

Methods

Data were analyzed from 63 patients (25 males, Mdn age [IQR]=23.0 [21.0], Mdn days since injury [IQR]=66.0 [112.0]) presenting to an interdisciplinary concussion clinic. HA disorders were diagnosed post-injury by a board-certified neurologist and obtained from medical records. Nearly half (51%) of the sample had a HA diagnosis. We analyzed the performance on CNSVS multiple test domains: Composite Memory, Psychomotor Speed, Complex Attention, and Cognitive Flexibility. Chi-square test of independence assessed differences in demographic and medical history factors among those with and without HA diagnosis. Multivariate analyses of covariance assessed the influence of HA on CNSVS multiple test domains. Factors significantly different between groups were added as covariates.

Results

There were significant interactions of loss of consciousness (LOC; Χ2(1, 63)= 6.22, p=.013), history of attention-deficit/hyperactivity disorder (ADHD; Χ2(1, 63)= 5.13, p=.023), and daytime sleepiness (Χ2(1, 63)= 6.14, p=.013) among those with and without HA diagnosis. The presence of these medical conditions composed 19%, 28%, and 40%, respectively, of HA diagnoses. There was no statistically significant omnibus effect of HA diagnosis on the four CNSVS domain scores without covariates (F[4, 58]= 0.46, p=.76, ηp2=.03) or when controlling for LOC, history of ADHD, and daytime sleepiness (F[4, 55]=0.44, p=.78, ηp2=.03).

Conclusion

Findings suggest that HA diagnosis is unrelated to performance on CNSVS in individuals after concussion.

Extended follow-up of the AdVance XP male sling in the treatment of male urinary stress incontinence after 48 months: Results of a prospective and multicenter study

OBJECTIVE

To evaluate the efficacy and safety of the AdVance XP male sling in a midterm follow-up for the treatment of male urinary incontinence in a selected patient cohort.

MATERIALS AND METHODS

In all, 115 patients with postprostatectomy incontinence were prospectively enrolled. A previous endoscopic evaluation of a sufficient coaptive zone in the repositioning test was mandatory. Patients with urine leakage in supine position or previous incontinence surgery were excluded. Postoperatively a standardized 24-hour pad test and pad usage were evaluated. To compare pre- and postoperative continence status nonparametric t test was used. A P-value of <.05 was seen as statistically significant.

RESULTS

Median preoperative urine loss in the 24-hour pad test was 272 g (min. 42-max. 1600) and was significantly improved at any point in follow-up. Success was defined as 0 pads per day and a maximum of 5 g in the 24-hour pad test. After a follow-up of 48 months, 71.7% of the patients were cured, whereas 15.0% of patients had an improved continence situation and 13.3% were classified as failed. Mean urine loss decreased significantly to 24.4 g (P ≤ .001). No severe intra- or postoperative complications are to be reported. Median follow-up was 4.2 years.

CONCLUSIONS

A stable effectiveness in a selected patient cohort can also be demonstrated in an extended follow-up. The complication rates are low and no late postoperative complications occurred, indicating the safety of the procedure.

[Differentiated surgical treatment of male stress urinary incontinence-between intention and reality?]

The differentiated surgical treatment of male urinary incontinence is a very interesting and sometimes also emotional topic, in which evidence is increasingly maturing. Nowadays, the most common surgical procedures are fixed sling and adjustable incontinence systems as well as the artificial urinary sphincter. The evidence for the procedures varies and there is currently a lack of prospective, comparative studies. The challenging question is: Which operation is the best for which patient? The following article is intended to give an overview of the surgical options and a constructive attempt to differentiate the indication.

Efficacy and safety of artificial urinary sphincter (AUS): Results of a large multi-institutional cohort of patients with mid-term follow-up

AIMS

To assess efficacy and safety as well as predictive factors of dry rate and freedom from surgical revision in patients underwent AUS placement. The artificial urinary sphincter (AUS) is still considered the standard for the treatment of moderate to severe post-prostatectomy stress urinary incontinence (SUI). However, data reporting efficacy and safety from large series are lacking.

METHODS

A multicenter, retrospective study was conducted in 16 centers in Europe and USA. Only primary cases of AUS implantation in non-neurogenic SUI after prostate surgery, with a follow-up of at least 1 year were included. Efficacy data (continence rate, based on pad usage) and safety data (revision rate in case of infection and erosion, as well as atrophy or mechanical failure) were collected. Multivariable analyses were performed in order to investigate possible predictors of the aforementioned outcomes.

RESULTS

Eight hundred ninety-two men had primary AUS implantation. At 32 months mean follow-up overall dry rate and surgical revision were 58% and 30.7%, respectively. Logistic regression analysis showed that patients without previous incontinence surgery had a higher probability to be dry after AUS implantation (OR: 0.51, P = 0.03). Moreover institutional case-load was positively associated with dry rate (OR: 1.18; P = 0.005) and freedom from revision (OR: 1.51; P = 0.00).

CONCLUSIONS

The results of this study showed that AUS is an effective option for the treatment of SUI after prostate surgery. Moreover previous incontinence surgery and low institutional case-load are negatively associated to efficacy and safety outcomes.

Comparison of adjustable male slings and artificial urinary sphincter in the treatment of male urinary incontinence: a retrospective analysis of patient selection and postoperative continence status

PURPOSE

To analyze and compare preoperative patient characteristics and postoperative results in men with stress urinary incontinence (SUI) selected for an adjustable male sling system or an artificial urinary sphincter (AUS) in a large, contemporary, multi-institutional patient cohort.

METHODS

658 male patients who underwent implantation between 2010 and 2012 in 13 participating institutions were included in this study (n = 176 adjustable male sling; n = 482 AUS). Preoperative patient characteristics and postoperative outcomes were analyzed. For statistical analysis, the independent T test and Mann-Whitney U test were used.

RESULTS

Patients undergoing adjustable male sling implantation were less likely to have a neurological disease (4.5% vs. 8.9%, p = 0.021), a history of urethral stricture (21.6% vs. 33.8%, p = 0.024) or a radiation therapy (22.7% vs. 29.9%, p = 0.020) compared to patients that underwent AUS implantation. Mean pad usage per day (6.87 vs. 5.82; p < 0.00) and the ratio of patients with a prior incontinence surgery were higher in patients selected for an AUS implantation (36.7% vs. 22.7%; p < 0.001). At maximum follow-up, patients that underwent an AUS implantation had a significantly lower mean pad usage during daytime (p < 0.001) and nighttime (p = 0.018). Furthermore, the patients' perception of their continence status was better with a subjective complete dry rate of 57.3% vs. 22.0% (p < 0.001).

CONCLUSIONS

Patients selected for an AUS implantation showed a more complex prior history and pathogenesis of urinary incontinence as well as a more severe grade of SUI. Postoperative results reflect a better continence status after AUS implantation, favoring the AUS despite the more complicated patient cohort.

Long-term functional outcome analysis in a large cohort of patients after radical prostatectomy

INTRODUCTION

Goal of the study was an analysis of functional outcomes after radical prostatectomy (RP) in a large cohort of patients.

METHODS

Functional outcomes were assessed with the ICIQ-SF questionnaire and daily pad-usage for the evaluation of stress urinary incontinence (SUI) as well as with the IIEF-5 score for the evaluation of erectile dysfunction (ED). Statistical analysis included log-rank test, Mann-Whitney-Test, ANOVA test and logistic regression (P < 0.05).

RESULTS

In total 4003 patients were included in the study. Median follow-up was 42 months (min. 2-max. 147 mo.). Regarding ED, an IIEF-5 score of ≥20 was reached by 39% of patients. Regarding SUI, 55% stated that they needed no pads, 21% of patients needed one pad per day. 33% of patients reported of no incontinence (0 p. in ICIQ), 26% of patients reported of a mild incontinence (1-5 p. in ICIQ). Patientś global impression of their overall health respectively patientś subjective quality of life were assessed with the EORTC QLC-C30 and were both high with a median of six points (on a scale of 1-7). In multivariate analysis time since surgery could be identified as independent risk factors on QOL (P = 0.0028), IIEF-5 (P = 0.0149), ICIQ (P < 0.001), and pads per day (P < 0.001).

CONCLUSIONS

Our data show a good continence status, a clearly impaired erectile function but overall a good quality of life after surgery. In summary older patients-with an advanced tumor and adjuvant radiation therapy-were at highest risk for an impaired functional outcome.

Pathophysiology and Contributing Factors in Postprostatectomy Incontinence: A Review

CONTEXT

The incidence and awareness of postprostatectomy incontinence (PPI) has increased during the past few years, probably because of an increase in prostate cancer surgery. Many theories have been postulated to explain the pathophysiology of PPI.

OBJECTIVE

The current review scrutinizes various pathophysiologic mechanisms underlying the occurrence of PPI.

EVIDENCE ACQUISITION

A search was conducted on PubMed and EMBASE for publications on PPI. The primary search returned 2518 publications. Animal and basic research studies, letters, publications on prostatectomy for benign reasons, pathology of prostatic carcinoma, radiotherapy and hormone therapy of prostatic carcinoma, and review articles were all used as criteria for exclusion from the study. A total of 128 publications were selected for final analysis.

EVIDENCE SYNTHESIS

Neuromuscular anatomic elements and pelvic support are known to influence PPI as evidenced by multiple publications. A number of non-anatomic and surgical elements have been postulated as contributing factors to PPI. Biological factors and preoperative parameters include: functional bladder changes, age, body mass index (BMI), pre-existing lower urinary tract symptoms (LUTS), prostate size, and oncologic factors. Multiple studies reported the impact of specific anatomic/surgical factors, including fibrosis, shorter membranous urethral length (MUL), anastomotic stricture, damage to the neurovascular bundle, and extensive dissection, all of which have a negative impact on the continence status of patients following radical prostatectomy (RP). Investigation of the impact of techniques to spare the bladder neck and additional procedures to reconstruct the posterior or anterior support structures (eg, the Rocco stitch) on continence status is ongoing.

CONCLUSIONS

Anatomic support and pelvic innervation appear to be important factors in the etiology of PPI. Biological/preoperative factors including greater age at time of surgery, pre-existing LUTS, high BMI, shorter MUL, and functional bladder changes have a negative impact on continence after RP. Extensive dissection during surgery, damage to the neurovascular bundle, and postoperative fibrosis also have a substantial negative impact on the continence status of men undergoing RP. Sparing of the bladder neck and anterior fixation of the bladder-urethra anastomosis are associated with better continence rates. There is still debate about whether posterior pelvic reconstruction leads to better postoperative continence rates.

PATIENT SUMMARY

Radical prostatectomy is an oncologic procedure and thus requires removal of the entire prostate gland and seminal vesicles, ideally with negative surgical margins. This sometimes results in urinary incontinence. The factors contributing to urinary incontinence are explained in this article.

Consensus Statement of the European Urology Association and the European Urogynaecological Association on the Use of Implanted Materials for Treating Pelvic Organ Prolapse and Stress Urinary Incontinence

CONTEXT

Surgical nonautologous meshes have been used for several decades to repair abdominal wall herniae. Implantable materials have been adopted for the treatment of female and male stress urinary incontinence (SUI) and female pelvic organ prolapse (POP).

OBJECTIVE

A consensus review of existing data based on published meta-analyses and reviews.

EVIDENCE ACQUISITION

This document summarises the deliberations of a consensus group meeting convened by the European Association of Urology (EAU) and the European Urogynecological Association, to explore the current evidence relating to the use of polypropylene (PP) materials used for the treatment of SUI and POP, with reference to the 2016 EAU guidelines (European Association of Urology 2016), the European Commission's SCENIHR report on the use of surgical meshes (SCENIHR 2015), other available high-quality evidence, guidelines, and national recommendations.

EVIDENCE SYNTHESIS

Current data suggest that the use of nonautologous durable materials in surgery has well-established benefits but significant risks, which are specific to the condition and location they are used for. Various graft-related complications have been described-such as infection, chronic pain including dyspareunia, exposure in the vagina, shrinkage, erosion into other organs of xenografts, synthetic PP tapes (used in SUI), and meshes (used in POP)-which differ from the complications seen with abdominal herniae.

CONCLUSIONS

When considering surgery for SUI, it is essential to evaluate the available options, which may include synthetic midurethral slings (MUSs) using PP tapes, bulking agents, colposuspension, and autologous sling surgery. The use of synthetic MUSs for surgical treatment of SUI in both male and female patients has good efficacy and acceptable morbidity. Synthetic mesh for POP should be used only in complex cases with recurrent prolapse in the same compartment and restricted to those surgeons with appropriate training who are working in multidisciplinary referral centres.

PATIENT SUMMARY

Synthetic slings can be safely used in the surgical treatment of stress incontinence in both male and female patients. Patients need to be aware of the alternative therapy and potential risks and complications of this therapy. Synthetic mesh for treating prolapse should be used only in complex cases with recurrent prolapse in specialist referral centres.

36-month data for the AdVance XP® male sling: results of a prospective multicentre study

OBJECTIVES

To evaluate the efficacy and safety of the AdVance XP^® sling (Boston Scientific, formerly American Medical Systems) in male stress urinary incontinence (SUI) after radical prostatectomy in a prospective multicentre study, as in recent years several studies have shown the effectiveness and safety of the AdVance sling for treating male SUI and in 2010 the second-generation AdVance XP was introduced with several changes in the sling design and a new needle shape.

PATIENTS AND METHODS

In all, 115 patients were included. Patients with nocturnal UI, previous UI surgery, previous radiotherapy and a coaptive zone of <1 cm in the preoperative repositioning test were excluded. Postoperatively, a standardised 24-h pad test, quality-of-life scores [International Quality of Life score (IQOL) and International Consultation on Incontinence Questionnaire short form (ICIQ-UI SF)], visual analogue scale (VAS) for pain, five-item version of the International Index of Erectile Function (IIEF-5), International Prostate Symptom Score (IPSS) and Patient Global Impression of Improvement (PGI-I) score, were performed. All patients with a 0-5 g pad test were defined as cured and improved with a reduction of urine loss of >50%. All others were classified as failures. Significance analysis was performed using the Wilcoxon test.

RESULTS

The mean (median) preoperative urine loss in the 24-h pad test was 272.0 (272.0) g. After a follow-up of 3 months (114 patients), 64.9% of the patients were cured and 31.6% had an improved continence status. The mean urine loss decreased significantly to 34.9 g (P < 0.001), with a mean VAS score of 0.5, and mean PGI-I of 1.5. After a follow-up of 24 months (80 patients), 68.8% of the patients were cured and 22.5% had improved. The mean urine loss decreased significantly to 19.1 g (P < 0.001), with a mean VAS score of 0.3, and mean PGI-I of 1.5. After a follow-up of 36 months (47 patients), 66.0% of the patients were cured and 23.4% had improved. The mean urine loss decreased significantly to 21.8 g (P < 0.001), with a mean VAS score of 0.0, and mean PGI-I of 1.6. The mean IQOL and ICIQ-UI SF improved significantly (both P < 0.001) after 36 months. There were no significant postoperative changes in IIEF-5 and IPSS. No intraoperative and no long-term complications occurred. No erosion or explanations occurred.

CONCLUSION

The AdVance XP shows good and stable effectiveness and low complication rates even at a mid-term follow-up of up to 36 months.

Prognostic Features for Objectively Defined Urinary Continence after Radical Cystectomy and Ileal Orthotopic Neobladder in a Contemporary Cohort

PURPOSE

We objectively quantified daytime and nocturnal continence rates, and defined predictive features for favorable continence outcomes after radical cystectomy and orthotopic ileal neobladder creation.

MATERIALS AND METHODS

At 1 institution 1,012 cystectomies were performed between 2004 and 2015. Questionnaires evaluating the continence status were sent to 244 patients. To objectify postoperative urine loss daytime and nocturnal pad tests were performed. Continence was defined as the need for up to 1 safety pad and urine loss 10 gm or less per test. Predefined associative features were tested for an influence on continence outcomes. Statistical analysis was done with the Fisher exact and Mann-Whitney U tests, and linear logistic regression models. Significance was considered at p <0.05.

RESULTS

A total of 188 patients (77.0%) returned the questionnaires. Median followup was 61 months. Median daytime pad use was 1 pad per day (range 0 to 9). Median daily urine loss based on standardized pad testing was 8 gm (range 0 to 2,400). During the night a median of 1 pad (range 0 to 7) was used and median nocturnal urine loss was 28.5 gm (range 0 to 1,220). The continence rate was 54.3% during the day and 36.3% at night. On multivariate analysis good preoperative ECOG (Eastern Cooperative Oncology Group) status (OR 2.987, p = 0.010), retained sensation of bladder filling (OR 6.462, p = 0.003) and preoperative coronary heart disease (OR 0.036, p = 0.002) were independent predictors of daytime success. Based on preoperative risk factors a simple predictive score for daytime continence was created (AUC 0.725, p <0.001).

CONCLUSIONS

Continence rates after orthotopic ileal neobladder creation are lower than previously described when objective continence definitions are applied. Patients with good performance status, without coronary heart disease and with retained sensation of orthotopic ileal neobladder filling have better daytime continence outcomes.

Test-retest reliability of high angular resolution diffusion imaging acquisition within medial temporal lobe connections assessed via tract based spatial statistics, probabilistic tractography and a novel graph theory metric

This study examined the reliability of high angular resolution diffusion tensor imaging (HARDI) data collected on a single individual across several sessions using the same scanner. HARDI data was acquired for one healthy adult male at the same time of day on ten separate days across a one-month period. Environmental factors (e.g. temperature) were controlled across scanning sessions. Tract Based Spatial Statistics (TBSS) was used to assess session-to-session variability in measures of diffusion, fractional anisotropy (FA) and mean diffusivity (MD). To address reliability within specific structures of the medial temporal lobe (MTL; the focus of an ongoing investigation), probabilistic tractography segmented the Entorhinal cortex (ERc) based on connections with Hippocampus (HC), Perirhinal (PRc) and Parahippocampal (PHc) cortices. Streamline tractography generated edge weight (EW) metrics for the aforementioned ERc connections and, as comparison regions, connections between left and right rostral and caudal anterior cingulate cortex (ACC). Coefficients of variation (CoV) were derived for the surface area and volumes of these ERc connectivity-defined regions (CDR) and for EW across all ten scans, expecting that scan-to-scan reliability would yield low CoVs. TBSS revealed no significant variation in FA or MD across scanning sessions. Probabilistic tractography successfully reproduced histologically-verified adjacent medial temporal lobe circuits. Tractography-derived metrics displayed larger ranges of scanner-to-scanner variability. Connections involving HC displayed greater variability than metrics of connection between other investigated regions. By confirming the test retest reliability of HARDI data acquisition, support for the validity of significant results derived from diffusion data can be obtained.

A Clinician's Guide to Avoiding and Managing Common Complications During and After Robot-assisted Laparoscopic Radical Prostatectomy

CONTEXT

Robot-assisted radical prostatectomy (RARP) is on the advance globally, and it is essential for surgeons and patients to know the rates of perioperative complications.

OBJECTIVE

To provide evidence-based clinical guidance on avoiding and managing common complications during and after RARP in the context of a comprehensive literature review.

EVIDENCE ACQUISITION

In concordance with the Preferred Reporting Items for Systematic Reviews and Meta-analysis 2015 statement guidelines, a literature search of the PubMed database from August 1, 2011, to August 31, 2015, using the predefined search terms robot* AND radical prostatectomy, was conducted. The search resulted in 653 unique results that were subsequently uploaded to DistillerSR (Evidence Partners, Ottawa, Canada) for team-based screening and processing of references.

EVIDENCE SYNTHESIS

Overall, 37 studies met the inclusion criteria and were included. Median rate of overall complication was 12.6% (range: 3.1-42%). Most of the complications were minor (Clavien-Dindo grades 1 and 2). Grade 3 complications comprised the bulk of the major complications with a median rate of 2.7%; grade IV and V complications were exceedingly rare in all reports.

CONCLUSIONS

Despite continued adoption of the RARP technique globally, rates of overall complication remain low. Many of the complications experienced during and after RARP can be mitigated and prevented by experience and the implementation of safe techniques.

PATIENT SUMMARY

Despite continued adoption of the robot-assisted radical prostatectomy (RARP) technique globally, rates of overall and major complications remain low at 12.6% and 2.7%, respectively. Complications can be minimized and successfully managed using established techniques. RARP is a safe and reproducible technique.

Mid-term outcomes after AdVanceXP male sling implantation

OBJECTIVE

To describe efficacy and safety of the AdVanceXP (Boston Scientific, Marlborough, MA, USA) retrourethral transobturator male sling after a mean follow-up of almost 3 years.

PATIENTS AND METHODS

A total of 41 patients underwent AdVanceXP implantation between July 2010 and March 2012 by a single surgeon. Patients were prospectively evaluated at baseline, after a mean follow-up of 12months and after an individual maximum follow-up. Efficacy was evaluated by daily pad usage, 24-h pad testing, and validated questionnaires (International Consultation on Incontinence questionnaire [ICIQ]). Patient satisfaction was determined using the Patient's Global Impression of Improvement score; quality of life was evaluated using the International Quality of Life (IQOL) score. Patients needing 0 or 1 safety pad with a daily urine loss <8 g were classified as cured. To assess the changes in outcome over time, a Wilcoxon signed-rank test was used. A P value <0.05 was taken to indicate statistical significance.

RESULTS

The mean ± sd follow-up was 33.1 ± 8.1 months. A total of four patients (9.8%) were lost to follow-up. At follow-up, 56.1% of patients used 0 or 1 dry safety pad, 17.1% used 1 pad, and 17.1% used 2 pads. Mean pad use was 0.6 pads per day (P < 0.001 vs baseline) with a mean urine loss of 14 g per day. After nearly 3 years, 46.3% of the patients could be classified as cured and 29.3% could be classified as improved. When comparing respective outcomes after 1 and 3 years, no significant changes in mean daily pad use (0.8 at 1 year; P = 1.000), in ICIQ score (5.0 at 3 years vs 5.2 at 1 year; P = 0.500), or in IQOL score (89.2 at 3 years vs 86.8 at 1 year; P = 0.500) were observed. Patients lost less urine based on 24-h pad testing after nearly 3 years (14 g at 3 years vs 28 g at 1 year; P = 0.106). Subgroup analyses showed no significant differences in efficacy in patients who had previously received radiotherapy or in patients with mild preoperative incontinence. Between 1 and 3 years postoperatively, no complications were detected.

CONCLUSIONS

The present study had the longest follow-up for AdVanceXP to date and is the first to show a high efficacy even after a mean follow-up of almost 3 years. The results indicate that late-onset complications are rare after AdVanceXP implantation.

[Urinary incontinence in men]

Stress urinary incontinence in men is predominantly iatrogenic whereby radical prostatectomy is the most common cause with persistent stress urinary incontinence rates varying between 10 % and 25 %. The first line therapy for postoperative male stress urinary incontinence is physiotherapy, especially pelvic floor muscle rehabilitation. If conservative treatment fails to show sufficient improvement, surgical therapy is recommended. Several treatment options are currently available for the surgical treatment of male stress urinary incontinence including artificial sphincters, adjustable and functional sling systems, bulking agents and implantable balloon systems.

Efficacy and safety of the ZSI375 artificial urinary sphincter for male stress urinary incontinence: lessons learned

PURPOSE

To analyze efficacy and safety for the ZSI375 artificial urinary sphincter in a multicenter case series.

METHODS

Thirteen male patients with stress urinary incontinence underwent implantation of a ZSI375 artificial urinary sphincter device between 2010 and 2012 in three international continence reference centers. Perioperative characteristics and postoperative complications were analyzed using the Clavien-Dindo scale. Re-hospitalization and explantation rates, and functional outcome were assessed. Inner-group and between-group differences were analyzed using Wilcoxon, Mann-Whitney U, and Fisher's exact test whenever indicated. Kaplan-Meier analysis was performed to assess device survival. A p value below 0.05 was considered statistically significant.

RESULTS

There were no intraoperative complications. Median follow-up was 13.5 months. In this period, four device defects (30.8 %) could be observed, being the main cause for device explantation, followed by device infection (15.4 %), non-resolvable pain (7.7 %), and urethral erosion (7.7 %). There were no Clavien IV or Clavien V complications. Overall explantation rate was 61.5 %. Mean time-to-explantation was 279 ± 308 days. There was no significant influence of previous irradiation and previous invasive incontinence therapy (p = 0.587 and p = 0.685, respectively). Mean daily pad usage decreased from 5.8 ± 1.5 to 2.4 ± 2.1 (p = 0.066). One patient (7.7 %) did not use any pads. Social continence (0-1 pads) was achieved in 15.4 % of the patients.

CONCLUSION

This is the most current study that is investigating the outcome after ZSI375 implantation in a multicenter case series. Based on our results, explantation rates after ZSI375 implantation are high and efficacy rates seem lower than previously described. Addressing this high failure rate, the system has undergone a two-step modification in the meantime.

Evaluation and Management of Postprostatectomy Incontinence: A Systematic Review of Current Literature

CONTEXT

Radical prostatectomy is the most common reason for male stress urinary incontinence. There is still uncertainty about its diagnostic and therapeutic management.

OBJECTIVE

To evaluate current evidence regarding the diagnosis and therapy of postprostatectomy incontinence (PPI).

EVIDENCE ACQUISITION

A systematic review of the literature was performed in October 2015 using the Medline database.

EVIDENCE SYNTHESIS

Diagnosis and conservative treatment of PPI are currently mostly based on expert opinions. Pelvic floor muscle training is the noninvasive treatment of choice of PPI. For invasive management of moderate to severe PPI, the artificial urinary sphincter is still the treatment of choice, but an increasing number of adjustable and nonadjustable, noncompressive as well as compressive devices are used more frequently. However, no randomized controlled trial has yet investigated the outcome of one specific surgical treatment or compared the outcome of different surgical treatment options.

CONCLUSIONS

The level of evidence addressing the surgical management of PPI is still unsatisfactory. Further research is urgently needed.

PATIENT SUMMARY

Incontinence after the removal of the prostate (postprostatectomy incontinence) is the most common cause of male stress urinary incontinence. First-line therapy is physiotherapy and lifestyle changes. If no satisfactory improvement is obtained, various surgical treatment options are available. The most commonly used is the artificial urinary sphincter, but other treatment options like male slings are also available.

AdVanceXP male sling: 2-year results of a multicentre study

PURPOSE

For the treatment of persistent post-prostatectomy incontinence (PPI), several surgical treatment options including male slings are available. In 2010, the second generation of the retrourethral male sling Advance, AdVanceXP, was introduced. Aim of the study was to examine in a prospective multicentre study the outcome of AdVanceXP in the treatment of PPI.

METHODS

Ninety-four patients were treated with AdVanceXP. Patients with nocturnal incontinence, previous incontinence surgery, with coaptive zone <1 cm and irradiated patients were excluded. Measurements included: daily pad usage, 24-h pad weight test, post-operative pain in the visual analogue scale, International Quality of Life questionnaire, International Consultation on Incontinence Questionnaire short form, IEEF5 and Patient Global Impression of Improvement. Adverse events were recorded. All patients with no pads and 0-5 g in the 24-h pad test were defined as cured and those with a reduction in urine loss >50 % as improved.

RESULTS

Preoperatively, the median 24-h pad weight test was 274 g and daily pad usage was 3. At 1-year follow-up, 66.3 % of patients could be classified as cured and 25.3 % as improved. After 2 years, 73.1 % could be classified as cured and 19.6 % as improved. Urine loss decreased (p < 0.001), and quality of life improved significantly (p < 0.001). Mean PGI was 1.5 after 1 year and 1.4 after 2 years. Majority of complications were minor. No intraoperative complications and five serious post-operative events occurred (grade IIIB complications). No explantation was necessary.

CONCLUSIONS

AdVanceXP, when correctly indicated, shows good effectiveness and low complication rates after up to 2 years.

Risk factors for artificial urinary sphincter failure

PURPOSE

To analyze revision rates and risk factors for artificial urinary sphincter failure.

METHODS

Eighty-four patients underwent implantation of an artificial urinary sphincter in one reference center. Continence rates were defined by daily pad usage. Influence of predefined risk factors for device explantation, revision, differences in preoperative pad usage, and device survival was analyzed using Chi-squared test, Wilcoxon signed-rank test, and Kaplan-Meier analysis. A multivariate analysis was performed using a logistic regression model. A p value below 0.05 was considered statistically significant.

RESULTS

After a mean follow-up of 39.7 months, the device was still in situ in 64 patients. In univariate analysis, perioperative need of anticoagulation led to a significant increase in urethral erosion (6 vs. 30 %; p = 0.002) and explantation rate (15 vs. 34 %; p = 0.047). Pelvic irradiation increased postoperative infection rates significantly (0 vs. 10 %; p = 0.018). Penoscrotal approach led to significant increase in urethral erosion rate (0 vs. 21 %; p = 0.015). Implantation of a double cuff led to a significant increase in explantation rate (58 vs. 24 %; p = 0.014), revision rate (75 vs. 38 %; p = 0.017), and infection rate (17 vs. 1 %; p = 0.008). When using cuff size of 3.5 cm, revision rate (20 vs. 50 %; p = 0.026) as well as incontinence rates (40 vs. 82 %; p = 0.014) was significantly lower. In multivariate analysis, only perioperative anticoagulation and double-cuff placement were independent predictors of artificial urinary sphincter failure.

CONCLUSIONS

Our findings highlight the influence of perioperative anticoagulative therapy. In addition, the current study provides further evidence that double-cuff implantation should be performed only with caution during primary implantation.

Efficacy and complications of the adjustable sling system ArgusT for male incontinence: results of a prospective 2-center study

OBJECTIVE

To evaluate prospectively the efficacy and the safety of the ArgusT in male patients with persistent stress urinary incontinence.

METHODS

A prospective 2-center evaluation was conducted on consecutive patients treated for persistent stress incontinence. Forty-two patients were implanted with the ArgusT male sling system with no associated surgery. Measurements included daily pad usage, 24-hour pad weight test, International Quality of Life questionnaire, International Consultation on Incontinence Questionnaire short form, and the Patient Global Impression of Improvement. Postoperative complications were assessed using the Clavien-Dindo classification. The definitions used were cured, 0-5 g in 24-hour pad weight test; improved, reduction of urine loss in 24-hour pad weight test >50%; and failed, all others.

RESULTS

After a mean follow-up of 28.8 months (20-38 months), 26 patients were dry (61.9%) with a pad test of 0-5 g/24 hours. Eleven patients (26.2%) improved. Five patients are considered failures. Overall daily pad use, urine loss in the 24-hour pad test, and quality of life scores improved significantly after sling implantation. Median adjustment rate was 1.7. There were no perioperative complications. Postoperative complications were mainly grade I and II complications according to the Clavien-Dindo classification.

CONCLUSION

The ArgusT sling system offers an effective and safe treatment option for male patients with moderate to severe stress urinary incontinence in a follow-up >2 years, even after radiotherapy.

[Rates of prostate-specific antigen testing for early detection of prostate cancer: a first comparison of German results with current international data]

OBJECTIVE

Measurement of prostate-specific antigen (PSA) is not only used as a screening instrument by urologists, but also by general practitioners and internal specialists (GP-IS). Until now, there are neither data on the approach of German GP-IS in practicing this nor have data been classified in the context of available international literature on this topic.

MATERIALS AND METHODS

Between May and December 2012, a questionnaire containing 16 items was sent to 600 GP-IS in Brandenburg and Berlin. The response rate was 65% (392/600). Six indicator questions (IQ1-6) were selected and results were set in the context of available international data. The quality of present studies was evaluated by the Harden criteria.

RESULTS

Of the 392 responding physicians, 317 (81%) declared that they would use PSA testing for early detection of PCA (IQ1) and, thus, formed the study group. Of these GP-IS, 38% consider an age between 41 and 50 years as suitable for testing begin (IQ2), while 53% and 14% of the GP-IS perform early detection until the age of 80 and 90 years, respectively (IQ3). A rigid PSA cut-off of 4 ng/ml is considered to be reasonable by 47% of the involved GP-IS, whereas 16% prefer an age-adjusted PSA cut-off (IQ4). Patients with pathological PSA levels were immediately referred to a board-certified urologist by 69% of the GP-IS. On the other hand, 10% first would independently control elevated PSA levels themselves after 3-12 months (IQ5). Furthermore, 14% of the interviewed physicians consider a decrease of PCA-specific mortality by PSA screening as being proven (IQ6). Knowledge regarding PCA diagnostics is mainly based on continuous medical education for GP-IS (33%), personal contact with urologists (6%), and guideline studies (4%). While 53% indicated more than one education source, 4% did not obtain any PCA-specific training. The results provided by this questionnaire evaluating response of German GP-IS to six selected indicator questions fit well into the international context; however, further studies with sufficient methodical quality are required.

CONCLUSIONS

Despite current findings and controversial recommendations of the two large PCA screening studies on this issue, German GP-IS still frequently use PCA screening by PSA measurement. Primary strategies of early detection as well as follow-up after assessment of pathologically elevated PSA levels poorly follow international recommendations. Thus, an intensification of specific education is justified.

[Use of botulinum toxin type A in non-neurogenic overactive bladder. Recommendations of the Working Group Urological Functional Diagnostics and Urology in Women]

The use of botulinum toxin for the treatment of neurogenic detrusor overactivity was first described in 2000 and thereafter botulinum toxin has also been used in non-neurogenic overactive bladder. In current guidelines intravesical injection of onabotulinumtoxin A in refractory patients is recommended. Our aim is to provide some clinically relevant recommendations from the Working Group Urologische Funktionsdiagnostik und Urologie der Frau for diagnostics and treatment with onabotulinumtoxin A of patients with non-neurogenic overactive bladder.

Pelvic floor muscle function is an independent predictor of outcome after retrourethral transobturator male sling procedure

PURPOSE

To evaluate the impact of the retrourethral transobturator sling (RTS) on pelvic floor muscle function (PFMF) and whether preoperative PFMF is associated with RTS outcome.

METHODS

Between May 2008 and December 2010, 59 consecutive men with postprostatectomy stress urinary incontinence (PSUI) underwent PFMF assessment before RTS and 6 months thereafter in a prospective cohort study. The assessments included demographic and clinical characteristics, and quality of life (QoL) questionnaires. PFMF was evaluated by digital rectal examination on the modified 6-point Oxford scale and by surface electromyography. The primary outcome measurement was success after RTS defined as PSUI cure with use of no or one dry "security" pad. For secondary outcome, PFMF, 1-h pad test, and impact of PSUI on QoL were evaluated. Uni- and multivariate analyses were performed.

RESULTS

After 6-month follow-up, the cure, improvement (>50 % pad reduction) and failure rates were 50 % (29/58 patients), 24 % (14/58 patients) and 26 % (15/58 patients), respectively. Significant improvement of QoL, clinical and PFMF parameters occurred after RTS. On multivariate analysis, weak PFMF (OR 86.29) and greater muscle fatigue (OR 3.31) were significant independent predictors of RTS failure. The final model demonstrated good calibration (p = 0.882) and excellent discriminative ability (0.942, 95 % CI 0.883-1.0) to predict success after RTS.

CONCLUSIONS

PFMF improved significantly after RTS procedure. Higher muscle fatigue and weak PFMF were independent predictors of RTS failure. Digital rectal evaluation of PFMF is a simple and reliable clinical tool, which can be used by urologists in daily routine to predict the RTS outcome.
