RESUMEN
PURPOSE: To report long-term results of artificial urinary sphincter implantation for urinary incontinence due to intrinsic sphincter deficiency in children. MATERIALS AND METHODS: This retrospective monocentric study included all patients who underwent artificial urinary sphincter (AMS 800) implantation before 18 years of age between 1986 and October 2018 for intrinsic sphincter deficiency. The primary outcome was the continence rate at the last follow-up, defined by the daily use of 0 pads. The secondary outcome was the overall survival of the device, defined as the absence of any repeated surgery (revision or explantation) during follow-up. Reoperation-free, revision-free, and explantation-free device survival rates were estimated using the Kaplan-Meier method. RESULTS: Thirty-six patients with a median age of 12 years (interquartile range [IQR]: 10-14) were included (15 females, 21 males). The median follow-up was 18.7 years (IQR: 9-26). The main underlying condition was spinal dysraphism (n = 24; 67%). The median time to the first reoperation was 9 years (IQR: 3.75-14.7). At the last follow-up, survival rates without revision were 84%, 71%, 55%, and 33% at 5, 10, 15, and 20 years, respectively. Survival rates without explantation were 91%, 84%, 80%, and 72% at 5, 10, 15, and 20 years, respectively. At the last follow-up, 29 patients had a functional device. The overall continence rate was 88%. All patients who had their device still in place were continent at the last follow-up. CONCLUSION: The artificial urinary sphincter is an effective long-term treatment for urinary incontinence related to intrinsic sphincter deficiency in children, providing a high rate of continence, even if associated with a high rate of reoperation.

INTRODUCTION AND HYPOTHESIS: To assess the effectiveness, safety and risk factors of failure and complications associated with Adjustable Continence Therapy (ACT®) balloons as a treatment for female stress urinary incontinence (SUI). METHODS: In the present multicentric retrospective study, all women implanted with ACT® balloons between 2000 and 2018 were considered eligible. Effectiveness and safety were assessed at 1 year, and risk factors for failure and complications were sought. The effectiveness was categorized into three distinct groups: Success = maximum 1 pad/day and patient's impression of improvement using a numerical rating scale (NRS) ≥ 8/10; Improvement = decrease of daily pad use and NRS ≥ 5/10; Failure = increase or stability of daily pad use or NRS < 5/10. The intra- and postoperative surgical complications were collected. RESULTS: Over the study period, 281 women were included. Among them, 104 (37.0%), 94 (33.5%) and 83 (29.5%) were categorized as success, improvement, and failure, respectively. Intra-, early and late postoperative complications occurred in 13 (4.6%), 35 (12.5%) and 75 (26.7%) women, respectively. Most early surgical complications were minor according to the Dindo-Clavien classification. Of women that presented a late postoperative surgical complication, 64 (22.8%) underwent an explantation performed under local or general anesthesia without associated sequalae. CONCLUSIONS: The short-term effectiveness associated with ACT® balloons, their minimally invasive implantation and the frequent but easily manageable and sequelae-free complications suggest that they should be part of the therapeutic arsenal for female SUI.

PURPOSE: In this study, we aimed at evaluating the long-term adjustable peri-urethral balloons (PUB) durability in both male and female with neurogenic or non-neurogenic stress urinary incontinence. MATERIAL AND METHODS: Each consecutive patient who underwent surgery for PUB placement before 2008 was included in this study. A PUB was proposed for patients with refractory to perineal reeducation stress urinary incontinence (SUI) caused by intrinsic sphincter deficiency. There were no exclusion criteria. Demographic, clinical and perioperative data were collected retrospectively from our clinical follow-up notes. RESULTS: A total of 177 patients were included in the study. Median [IQR] follow-up was 5 years [1.8-11.2]. The 3 main causes of SUI were radical prostatectomy (n=82, 46.3%), idiopathic intrinsic sphincter deficiency (n=55, 31.1%) and neurogenic sphincter deficiency (n=32, 18.1%). Complete continence (no pad necessary) was achieved for 109 patients (61.6%). At the end of the follow-up, the PUB global survival rate was 47.5% (Fig. 1). Median [IQR] PUB survival without removal was 57.8 months [42.3-81.7]. PUB survival without failure rate was 68.4% accounting for a median [IQR] survival duration of 116.9 months [86.2-176.9] CONCLUSION: In this study, we evidenced acceptable long-term efficiency and survival of PUB in the management of SUI in both neurogenic and non-neurogenic population. Given those results it could be a good alternative to AUS on unfit or unwilling population.

AIMS: To compare efficacy and safety between neurogenic and non-neurogenic women after adjustable continence therapy (ACT®) balloons implantation to treat stress urinary incontinence (SUI) due to intrinsic sphincter deficiency. METHODS: In the present retrospective multicentric study, all neurogenic and non-neurogenic women implanted with ACT® balloons between 2000 and 2018 were considered for inclusion. Efficacy was compared 1 year after implantation, and women were allocated in three different groups as follows. Success: maximum 1 pad per day and patient's impression of improvement assessed using a numeral rating scale (NRS) ≥8/10. Improvement: decrease of daily pad use and/or NRS ≥5/10. Failure: increase or stability of daily pad use or NRS <5/10. Overall surgical complications and explantations were compared 1 year after implantation. RESULTS: Among the 277 included women, 51 presented with a neurologic underlying disease. Mean age at implantation was 68.5 years. There was no significant difference in efficacy between neurogenic and non-neurogenic women with a success rate of 39.2% and 36.3%, respectively (p = 0.69). Similarly, improvement rate was reported to be 31.4% and 33.6%, in neurogenic and non-neurogenic women, respectively (p = 0.92). The overall surgical complications rate (24% vs. 34.5%, p = 0.15) and the explantation rate (19.6% vs. 28.8%, p = 0.18) were not significantly different. CONCLUSION: ACT balloons may be proposed to treat mixed or SUI in females with ISD. Efficacy and safety profiles appear to be similar in both neurogenic and non-neurogenic patients.

PURPOSE OF REVIEW: Urethral bulking agents are an effective treatment for stress urinary incontinence in select females. The material and techniques used for urethral bulking are constantly evolving. With the introduction of several new agents, there is an ongoing debate over which agent is the most effective, durable, and safe. RECENT FINDINGS: Current available bulking agents include Bulkamid®, Macroplastiue®, Durasphere®, Coaptite®, or Urolastic®. Each of these agents has its own biophysical properties that affect its efficacy and safety. Evidence evaluating bulking agents has increased over time but there is no definitive data that suggest superiority of one agent over another. The ideal urethral bulking agent for female stress incontinence has yet been identified. Currently available agents have acceptable short-term and medium-term efficacy with few adverse events.

PURPOSE: Artificial urinary sphincter (AUS) implantation in female patients results in high satisfaction rates and high functional outcomes, but implantation can be challenging and explantation of the device is fairly common. The objective of this study was to review outcomes after AUS explantation in women. METHODS: This is a retrospective, monocentric study of all women who underwent open or laparoscopic AUS implantation between November 1994 and July 2019, and patients with AUS explantation were included. Management after AUS explantation using descriptive analysis was assessed. RESULTS: Over a span of 26 years, 111 women had an AUS implanted by a single surgeon. Of these surgeries, 35 explantations in 29 patients were later required: 20 initial AUSs, nine revised AUSs and six reimplanted AUS (rAUSs). The median time to explantation was 15.5 month (± 0.55). After explantation, 13 rAUSs in 10 patients were successful and two attempts failed. The median time between explantation and rAUS was 8 months (± 0.95). At the last follow-up, five patients still had their rAUS and six rAUSs had required explantation after a median time of 6.5 months (± 0.65). Surgery was still possible for 12 patients who did not have a rAUS: three cystectomies, one bladder neck closure with continent urinary diversion, and six mid-urethral slings or adjustable continence therapy balloon implantations. Among the 23 patients who did not need a cystectomy or a bladder neck closure with continent urinary diversion, four were completely dry (17.4%), 11 were improved (47.8%), and eight (34.8%) experienced unchanged incontinence with the post-explantation management. Limitations include retrospective design, heterogeneous management over time and a relatively small population of patients in our cohort. CONCLUSION: Reimplantation of an AUS after an explantation seems feasible after at least 6 months. However, the surgery will be more difficult and satisfaction is not guaranteed. Multicenter databases should be created to help surgeons and patients decide on appropriate management strategies after explantation of an AUS.

PURPOSE: To report the early experience of a modified technique of robot-assisted artificial urinary sphincter (AUS) implantation in female, with a posterior approach to the bladder neck and intraoperative real-time cystoscopic monitoring. METHODS: Retrospective monocentric study included all consecutive female who underwent a primary robot-assisted AUS implantation between 2017 and 2019. Real-time intraoperative cystoscopic monitoring was carried out to check the correct level of the dissection and to avoid any injury during bladder neck dissection. Perioperative and intraoperative data, functional outcomes and complications were assessed. Continence was defined as 0 to 1 pad per day. RESULTS: Twenty-four patients were included, the median age was 66 years, 23/24 (96%) had previous SUI or prolapse surgery. Two conversions to open surgery and 2 modifications of the surgical technique with anterior dissection of the bladder neck were required due to major vesicovaginal adhesions. Overall, 20 patients underwent the robotic posterior approach. Eleven intraoperative complications in 10 patients (50%) occurred, including 7 bladder injuries 4 vaginal injuries, without the need to stop the procedure. The median hospital stay was 3 days (2-7). One AUS was removed at 1 year due to vaginal erosion. At last follow-up (median 26 months (22-36)), 95% of the devices were in place and activated and the continence rate was 84%. CONCLUSIONS: Early functional results of robot-assisted AUS implantation with a posterior approach to the bladder neck and intraoperative cystoscopic monitoring are promising despite the high rate of intraoperative complications due to previous surgeries. Further evaluation of this technique is required.

PURPOSE: To report the outcomes of AUS in women with neurological SUI resulting from intrinsic sphincter deficiency after a follow-up from 3 to 20 years. METHODS: The charts of female with moderate to severe neurological SUI who underwent open or laparoscopic AUS implantation between November 1994 and July 2014 were reviewed retrospectively. All patients were operated by a single experienced surgeon. Primary endpoint was a postoperative continence categorized as complete continence (no pads used), improved incontinence or unchanged incontinence. RESULTS: Twenty-three women (mean age 54 years, range 19-77) underwent open or laparoscopic AUS implantation. At the last follow-up, 7 (30.4%) initial artificial urinary sphincters remained in situ and 9 (39.1%) patients had at least one revision or reimplantation. Sixteen patients were fully continent (69.6%), four (17.4%) had improved incontinence and three (13.0%) had unchanged incontinence. After a median follow-up of 11.6 years (3-22), 8 (34.8%) explanations in 7 patients and 16 (69.6%) revisions in 11 patients occurred. The average time without explanation or revision was 10.9 and 8.5 years, respectively. Survival rates without AUS explanation were 94.4%, 76.5%, 72.8%, 50% and without revision were 83.3%, 64.7%, 45.5% and 16.7% at 5, 10, 15 and 20 years, respectively. CONCLUSION: Although all methods are imperfect at best, AUS remain toward our experience a good way to achieve long-term continence in female patients suffering from neurological SUI with preserved manual dexterity.

INTRODUCTION AND HYPOTHESIS: This study aimed to report 3-year completed follow-up of the safety and efficacy of Macroplastique® (MPQ) in women with stress urinary incontinence (SUI) due to intrinsic sphincter deficiency (ISD). METHODS: This is a retrospective analysis of all women who completed 3-year follow-up post-MPQ injection(s) at ten medical centers. We used the ROSE registry data report of Macroplastique® [Macroplastique® Real-time Observation of Safety and Effectiveness (ROSE) registry P040050/PAS001 on 2017]. Subjective incontinence outcome and adverse effects were assessed. RESULTS: The study included all patients (n = 70) who completed 3-year follow-up after the last MPQ injection. Twenty-four of 70 (34%) patients had two injections; 21/70 (30%) patients reported Stamey grade 0 and 28/70 (40%) reported Stamey grade 1. The overall patient satisfaction was 68% who completed 3-year follow-up. The composite success rate (I-QoL, PGI-S, and Stamey grade improvement) was 51.4%. No serious adverse events (AE) were reported within the completed 3-year follow-up. CONCLUSIONS: MPQ was found to be safe and efficacious for the treatment of SUI secondary to ISD in women. The overall high satisfaction rate was sustained from baseline to 3 years post-injection. Most complications were minor and transient without sequelae.

AIM: To determine the prevalence of stress urinary incontinence (SUI) and intrinsic sphincter deficiency (ISD) in women with stage IV pelvic organ prolapse. METHODS: Retrospective analysis of women with stage IV prolapse who underwent multichannel urodynamic testing. Abdominal leak point pressures (ALPP) and maximum urethral closure pressures (MUCP) were recorded. ISD was defined as ALPP ≤60 cm of water and/or MUCP ≤20 cm of water. Percentages were used to present the proportion of subjects diagnosed with SUI and ISD. RESULTS: A total of 145 patients met inclusion criteria. Mean age was 69 years; most patients were Caucasian (56%). Eighty-two (56%) patients were found to have SUI on urodynamic testing. Thirty-six (44%) of these were asymptomatic and identified as having occult SUI. Sixteen (19.5%) patients were diagnosed with ISD using ALPP and/or MUCP. Six (37%) of the ISD patients had at least one MUCP value ≤20 cm of water and 12 (75%) had observed leakage with at least one ALPP value ≤60 cm of water. The number of patients with leakage at ALPP ≤60 cm of water increased with increasing bladder volumes. Five ISD patients (31%) had ALPP ≤60 cm of water at 200 mL, six (37.5%) had ALPP ≤60 cm of water at 300 mL and seven (43.8%) had ALPP ≤60 cm of water at 400 mL. CONCLUSION: Greater than 50% of patients with stage IV pelvic organ prolapse had SUI on urodynamic testing, and 20% were found to have ISD. Of the patients diagnosed with SUI, 40% were asymptomatic. These findings may assist in counseling and preoperative planning for women with stage IV prolapse.

INTRODUCTION: To evaluate outcomes following urethral Macroplastique (MPQ) injection in women with stress urinary incontinence (SUI) following suburethral sling removal (SSR) for synthetic sling complications. METHODS: Following Institutional Review Board approval, charts of non-neurogenic women with SUI after SSR who underwent MPQ injection(s) and had at least 6 months minimum follow-up were reviewed from a prospectively maintained database. Demographic data, questionnaire (Urogenital Distress Inventory-6 [UDI-6] and Quality of Life) scores, and pad usage were recorded. Patients were followed with repeat questionnaires and three-dimensional ultrasound evaluating MPQ volume. Success following MPQ was defined as a composite score of a UDI-6 question 3 score of 0 to 1 at last visit and no additional anti-incontinence therapy. RESULTS: From 2011 to 2018, 70 women with mean age 62.7 years met study criteria. At a mean follow-up of 46.4 ± 1.5 months, the success rate after the first MPQ injection was 46%. Following a repeat MPQ injection when indicated, the overall success rate for the entire cohort was 69%. Despite the objective failure, the majority of patients reported subjective improvement (83%) and reduced pad usage (78%). On multivariate analysis: age, body mass index, previous hysterectomy, hormone replacement therapy, type of sling removed and baseline urodynamics (UDS) parameters were not predictors of MPQ failure. Higher parity was a predictor of MPQ failure (hazard ratio = 1.980; P = .032). CONCLUSION: MPQ injection is a durable and effective management option for SUI following SSR, although a second injection may be required to achieve the desired success.

INTRODUCTION AND HYPOTHESIS: To study the surgical outcomes and risk factors for failure of three types of mid urethral slings(MUS) surgeries in elderly and old age women with urodynamic stress incontinence(USI). METHODS: Three different types of MUS surgeries [single incision sling(SIS), trans-obturator tape(TOT), retro-public mid-urethral sling-tension-free vagina tape (TVT)]were performed among three age groups of women (young <64 yr, elderly 65-74 yr and old >75 yr) with USI. They were followed up for 1 year. RESULTS: Complete postoperative data was available for 688 women. After 1 year, overall objective cure rate was 88.2% and subjective cure rate was 85.9%. Among the young, elderly, and old age women objective cure rates were 91.0%, 80.6%, 66.7% and subjective cure rates were 89.2%, 77.6%, 58.3% respectively. Urodynamic parameters demonstrated flow rate, higher post-void bladder residual, smaller cystometric capacity, and lower maximum urethral closure pressure were significantly lower among old and elderly group. Subjectively, urinary distress inventory-6 (UDI-6) and incontinence impact questionnaire-7(IIQ-7) improved significantly in all groups with significant changes from baseline only in older women. Intrinsic sphincter deficiency(ISD) was found to be significantly associated with failure in older women. Other preoperative comorbidities were equally distributed among all the three age groups. The operative time, perioperative complications, and length of hospital stay showed no difference between the study groups. CONCLUSIONS: MUS surgery is safe for the young and aging patients with USI and demostrated significant improvement in its outcomes, but objective and subjective cure rates decreases with age. ISD was also found to be significantly associated with failure.

OBJECTIVES: To describe a new technique for robot-assisted AMS-800 artificial urinary sphincter (AUS) bladder neck implantation in women. PATIENTS AND METHODS: We reviewed the medical files of patients who underwent robot-assisted AUS implantation between March 2017 and November 2018 at our centre. All of the implantations were performed using a posterior approach to the bladder neck in order to avoid blind dissection and the risk of vaginal and/or bladder injury. This strategy was viewed as an alternative to the anterior robot-assisted implantation recently described. The AUSs were activated 5 weeks after implantation. Patients were followed up at 3, 6 and 12 months, then annually. RESULTS: Eight patients, with a median age of 64 years, underwent robot-assisted AUS implantation via a posterior approach to the bladder neck. The median preoperative pad weight was 300 g/24 h. The median operating time was 244 min. No peri-operative vaginal and or bladder injuries were observed. At a median of 12 months of follow-up, all the AUSs were functional. Five patients required no protection (62.5%), three had day protection (37.5%), and all said they were satisfied except for one patient (12.5%) who requested treatment for persistent urge incontinence. CONCLUSION: Robot-assisted AUS implantation in women via a posterior approach to the bladder neck is a procedure that is simple, reproducible and safe. The short-term functional results are satisfactory and comparable to those obtained via an open approach. A more long-term comparison of the efficacy and longevity of AUSs implanted using this posterior approach is needed to confirm its benefit compared with the anterior robot-assisted approach and the classic open technique.

AIMS: We aimed to assess the alterations in specific molecular mechanisms associated with collagenolysis and their correlation in cases of stress urinary incontinence (SUI) by urethral hypermobility (UH) and by intrinsic sphincter deficiency (ISD). METHODS: We evaluated the messenger RNA (mRNA) expression of matrix metalloproteinases (MMP1, MMP2, and MMP9), specific tissue inhibitors of metalloproteinases (TIMPs), and associated proteins (TIMP1, TIMP2, and α-2-macroglobulin [A2McG]) in the suburethral tissue of women with SUI (half with SUI by UH and half with SUI by ISD) by reverse-transcriptase quantitative polymerase chain reaction and determined the correlations of the expression of these proteins on each pathological condition. RESULTS: In the suburethral tissue, we found significantly altered MMP2 mRNA levels, being higher in women with ISD than in those with UH. Still, MMP1 and MMP9 exhibited a tendency to a higher expression in women with ISD. Concerning the TIMPs expression, no significant statistical differences were found between women with UH and ISD. When evaluating the MMP/TIMP ratios, we found significant statistical differences between MMP9/TIMP1 and MMP9/A2McG. In fact, the correlations of the expression MMP9 with TIMP1 and A2McG were lost for women with UH. The ratios between MMP1/TIMP1 and MMP1/A2McG were similar, although there was a tendency of higher ratio in ISD for MMP2/TIMP2 and MMP2/A2McG. CONCLUSION: Our results point toward higher collagenolysis in the suburethral tissue of women with SUI by ISD.

OBJECTIVE OF THE STUDY: To analyze the medium-term results and complications of the artificial urinary sphincter (AUS) AMS 800 implanted using laparoscopic robot surgery in women with stress urinary incontinence (SUI) due to intrinsic sphincter deficiency (ISD). DESIGN, SETTING, AND PARTICIPANTS: We conducted a prospective cohort study, which included all procedures done in the CHU of Nîmes from July 2015 to January 2017. Patients with SUI by ISD needing an AUS or patients with a malfunctioning AUS needing to be changed were included. We collected data on intraoperative complications, length of hospitalization, postoperative complications, continence rate at twelve months and satisfaction of patients. RESULTS: Nineteen patients were included, 10 for primo-implantation and 9 for AUS revision. There were 4 postoperative bladder injuries, of which 2 led to laparoconversions. The mean length of hospitalization was 4.1days. Three patients had postoperative complications, which needed an intervention without AUS removal. One patient with persisting SUI due to bladder weakness preferred AUS ablation rather than having a cuff change. There was a median follow-up of 22months (12 to 33months). Sixteen patients out of 19 were completely continent and were satisfied of their intervention and the improvement of their quality of life. CONCLUSION: The laparoscopic robot surgery for AUS implantation is safe and reproducible with good medium-term results. LEVEL OF EVIDENCE: 4.

This study investigated the effect of muscle-derived stem cells (MDSCs) and adipose tissue-derived stem cells (ADSCs) in the treatment of stress urinary incontinence (SUI) and their differences in a rat model. MDSCs and ADSC were isolated from rats (n = 10), examined for their properties, and labeled with enhanced green fluorescent protein (EGFP) and ß-galactosidase (ß-gal) gene. Rats received bladder-neck and transurethral sphincter injection of EGFP-labeled MDSCs and ß-gal gene-labeled ADSC and injection of D-Hanks as a control (n = 24 each group). At 0, 15, 30, and 60 days after cells injection, urinary voiding function was assessed by urine dynamics detector. The rats were killed to harvest their urethras for tracking of MDSCs and ADSC. Western blotting and quantitative real-time reverse transcription PCR (qRT-PCR) was performed to detect smooth muscle contents. Urodynamic test showed that MDSCs and ADSC improved the function of urination in rats with intrinsic sphincter deficiency (ISD), and effect of MDSCs-treatment was more pronounced. In addition, histologic analysis showed that the MDSCs and ADSC-treated groups had significantly higher myosin and α-smooth muscle actin (α-SMA) content than the control group. Compared with ADSC-treated groups, the MDSCs-treated groups in myosin and α-SMA content showed the tendency of increase. In summary, MDSCs and ADSCs have obvious effects in the treatment and/or prevention of ISD and transplantation of MDSCs is more effective than ADSC. © 2018 IUBMB Life, 70(10):976-984, 2018.

INTRODUCTION AND HYPOTHESIS: We report our experience with the Remeex system™ in women with recurrent stress urinary incontinence (SUI) or intrinsic sphincter deficiency (ISD). METHODS: A multicenter retrospective study was conducted in women who underwent an adjustable sling procedure between 2011 and 2016. We used urodynamic studies (UDS) preoperatively and the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF) and cough stress test (CST) pre- and postoperatively. Primary outcomes were subjective (no leakage reported by the patient) and objective (no leakage during CST) cure and improvement rates (reduction of ≥4 points in ICIQ-SF). Descriptive and inferential statistics were employed. RESULTS: A total of 50 patients were included. Mean age was 62 years (SD ± 11.35). Median follow-up was 19.5 months [interquartile range (IQR) 12.95-41.38]. Urinary incontinence (UI) was described as moderate and severe by 8 (16%) and 42 (84%) patients, respectively, and 25 (50%) had stress-predominant mixed urinary incontinence (MUI). Objective and subjective cure rates were 90% and 48%, respectively, while 82% of patients achieved improvement. Impact of UI on quality of life (QoL) improved from 10 (IQR 9-10) to 2 (IQR 0-5) (p < 0.0001). Clavien-Dindo II complications occurred in 14 (28%) patients, and one (2%) had IIIa. Tape erosion occurred in one (2%) patient, and five (10%) required readjustments. Logistic regression identified MUI [odds ratio (OR) 3.3, 95% confidence interval (CI) 1.02-10.89] and vaginal atrophy (OR 4.2, 95% CI 1.06-16.03) as predictors of low subjective cure rate. CONCLUSIONS: Adjustable slings represent a valuable and safe option in the management of recurrent SUI or ISD, with improvement in QoL. Results should be carefully interpreted due to our small sample and retrospective design.

PURPOSE: To analyze the functional outcomes over time of ACT balloon in women with stress urinary incontinence (SUI) secondary to intrinsic sphincter deficiency (ISD). METHOD: All patients with SUI secondary to ISD who underwent bilateral ACT balloon implantation between September 2008 and November 2015 and regularly monitored for a period of at least 24 months were eligible. The results were studied at 6, 12 and 24 months. Efficacy was defined as: Success - maximum 1 safety pad per day and visual analogue scale (VAS) rating≥9/10. Improvement - decrease in the number of pads used per day and VAS≥5/10. Failure - increase or stability of the number of pads used per day and/or VAS<5/10. Failure was considered as primary when it occurred without any success or improvement. It was considered as secondary when it occurred after an initial period of success or improvement. RESULTS: 18 patients were monitored during 24 months. The success rate was respectively 17 %, 33 % and 33 % at 6, 12 and 24 months of follow-up. The improvement rate was respectively 61 %, 39 % and 17 % at 6, 12 and 24 months of follow-up. The primary failure rate was 22 %. The secondary failure rate was 6 % at 12 months and 33 % at 24 months of follow-up. CONCLUSION: ACT balloon efficacy tends to decrease with time requiring a long-term follow-up of implanted patients. LEVEL OF EVIDENCE: 4.

OBJECTIVE: The aim of the study was to report the very long-term functional outcomes of artificial urinary sphincter (AUS) in male neurological patients. MATERIAL AND METHODS: Male neurological patients diagnosed with stress urinary incontinence due to sphincter deficiency and undergoing AUS (AMS 800®) implantation between 1985 and 1992 were enrolled. Continence, defined by no pad/condom usage, explantation and revision rates were reported. RESULTS: Fourteen patients with a median age of 27.3 years (IQR: 27.3-40.8) were included: four had a spinal cord injury and ten a spina bifida. Prior continence surgery was reported by 6 patients (42.9 %). Artificial urinary sphincter was implanted in a peribulbar (n=4) or periprostatic position (n=10). Median follow-up was 18.3 years (IQR: 10.1-20.3). At last follow-up, all patients were alive. Three native devices were still in place, eight were revised (four of them were secondarily explanted) and three were explanted due to erosion or infection. The 5-, 10-, 15-, 20-year explantation-free survival rates were respectively 85.7, 62.3, 52.0, 39.0 %. The 5-, 10-, 15-, 20-year revision-free survival rates were respectively 78.6, 42.9, 28.6, 7.1 %. At last follow-up, 50 % patients were continent. CONCLUSION: In the very long run, AUS provided a 50 % continence rate in male neurological patients but the revision rates were important. LEVEL OF EVIDENCE: 4.
