RESUMO
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.

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.

AIMS: To comparatively analyse outcomes after ARGUS classic and ArgusT adjustable male sling implantation in a real-world setting. METHODS: Inclusion criteria encompassed: non-neurogenic, moderate-to-severe stress urinary incontinence (≥2 pads), implantation of an ARGUS classic or ArgusT male sling between 2010 and 2012 in a high-volume center (>150 previous implantations). Functional outcomes were assessed using daily pad usage, 24-hour pad testing, and International Consultation on Incontinence (ICIQ-SF) questionnaires. Continence was defined as zero pads per 24 hours. Complications were graded using Clavien-Dindo scale. For multivariate analysis, binary logistic regression models were used (P < .05). RESULTS: A total of 106 patients (n = 74 [ARGUS classic], n = 32 [ArgusT]) from four centers were eligible. Median follow-up was 44.0 months (24-64). Patient cohorts were well-balanced. We observed a statistical trend in favor of ARGUS classic regarding postoperative urine loss based on standardized 24-hour pad test (71 ± 162 g [ARGUS classic] vs 160 ± 180 g [ArgusT]); P = .066]. Dry rates were 33.3% (ARGUS classic) and 11.8% (ArgusT, P = .114). In multivariable analysis, ArgusT male sling could not be confirmed as an independent predictor of decreased success (OR, 0.587; 95% CI; 0.166-2.076, P = .408). There were no Clavien IV and V complications. Inguinal pain was significantly higher after ArgusT implantation (P = .033). Explantation rates were higher for ArgusT compared to ARGUS classic (14.0 vs 23.3%; P = .371). Longer device survival for the ARGUS classic male sling was observed in Kaplan-Meier analysis (P = .198). CONCLUSIONS: In the largest comparative analysis of ARGUS classic and ArgusT male sling with the longest follow-up to date, we observed low continence rates with superior functional outcomes and decreased explantation rates after ARGUS classic implantation.

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.

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.

PURPOSE: To compare the efficacy and perioperative complications of the AdVanceXP with the original AdVance male sling. METHODS: We retrospectively enrolled 109 patients with an AdVance and 185 patients with an AdVanceXP male sling. The baseline characteristics and complication rates were analyzed retrospectively. Functional outcome and quality of life were evaluated prospectively by standardized, validated questionnaires. The Chi2-test for categorical and Mann-Whitney U test for continuous variables were performed to identify heterogeneity between the groups. RESULTS: Regarding operation time, there was no significant difference between the slings (p = 0.146). The complication rates were comparable in both groups except for postoperative urinary retention. This occurred significantly more often in patients with the AdVanceXP (p = 0.042). During follow-up, no differences could be identified regarding ICIQ-SF, PGI or I-QoL or number of pad usage. CONCLUSIONS: The AdVance and AdVanceXP are safe and effective treatment options for male stress urinary incontinence. However, the innovations of the AdVanceXP sling did not demonstrate a superiority over the original AdVance sling regarding functional outcome.

INTRODUCTION: To evaluate the safety and efficacy of the TiLOOP® male sling (pfm medical, Cologne, Germany) used in the treatment for male stress urinary incontinence (SUI). MATERIAL AND METHODS: We retrospectively evaluated a total of 34 patients with a TiLOOP® male sling. Perioperative complication rates were assessed and validated questionnaires were prospectively evaluated to assess quality of life and satisfaction rate. Outcome and complication rates were analysed by using descriptive statistics. Correlation of continence outcome and risk factors was performed with the chi-square test. A p value below 0.05 was considered statistically significant. RESULTS: The majority of patients (70.6%) were diagnosed with mild or moderate male SUI. During surgery, one instance (2.9%) of intraoperative urethral injury was observed. There were no immediate postoperative complications. The mean follow-up time was 44.6 months. An improvement of male SUI was reported by 61.9% of the patients and 38.1% reported no change according the Patient Global Impression of Improvement. The mean perineal pain score was 0.5 according to the international index of pain. CONCLUSIONS: The TiLOOP® is a safe treatment option for male SUI in our cohort with a low complication rate. However, the functional outcome of the TiLOOP® was inferior when compared to the outcome of the AdVance® male sling.

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.

INTRODUCTION: We analysed the impact of predefined risk factors: age, diabetes, history of pelvic irradiation, prior surgery for stress urinary incontinence (SUI), prior urethral stricture, additional procedure during SUI surgery, duration of incontinence, ASA-classification and cause for incontinence on failure and complications in male SUI surgery. MATERIALS AND METHODS: We retrospectively identified 506 patients with an artificial urinary sphincter (AUS) and 513 patients with a male sling (MS) in a multicenter cohort study. Complication rates were correlated to the risk factors in univariate analysis. Subsequently, a multivariate logistic regression adjusted to the risk factors was performed. A p value <0.05 was considered statistically significant. RESULTS: A history of pelvic irradiation was an independent risk factor for explantation in AUS (p < 0.001) and MS (p = 0.018). Moreover, prior urethral stricture (p = 0.036) and higher ASA-classification (p = 0.039) were positively correlated with explantation in univariate analysis for AUS. Urethral erosion was correlated with prior urethral stricture (p < 0.001) and a history of pelvic irradiation (p < 0.001) in AUS. Furthermore, infection was correlated with additional procedures during SUI surgery in univariate analysis (p = 0.037) in MS. CONCLUSIONS: We first identified the correlation of higher ASA-classification and explantation in AUS. Nevertheless, only a few novel risk factors had a significant influence on the failure of MS or AUS.

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.

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.

UNLABELLED: Background/Aims/Objectives: To analyze perioperative complication and short-term explantation rates after perineal or penoscrotal single-cuff and double-cuff artificial urinary sphincter (AUS) implantation in a large middle European multi-institutional patient cohort. METHODS: 467 male patients with stress urinary incontinence underwent implantation of a perineal single-cuff (n = 152), penoscrotal single-cuff (n = 99), or perineal double-cuff (n = 216) AUS between 2010 and 2012. Postoperative complications and 6-month explantation rates were assessed. For statistical analysis, Fisher's exact test and Kruskal-Wallis rank sum test, and a multiple logistic regression model were used (p < 0.05). RESULTS: Compared to perineal single-cuff AUS, penoscrotal single-cuff implantation led to significantly increased short-term explantation rates (8.6% (perineal) vs. 19.2% (penoscrotal), p = 0.019). The postoperative infection rate was significantly higher after double-cuff compared to single-cuff implantation (6.0% (single-cuff) vs. 13.9% (double-cuff), p = 0.019). The short-term explantation rate after primary double-cuff placement was 6.5% (p = 0.543 vs. perineal single-cuff). In multivariate analysis, the penoscrotal approach (p = 0.004), intraoperative complications (p = 0.005), postoperative bleeding (p = 0.011), and perioperative infection (p < 0.001) were independent risk factors for short-term explantation. CONCLUSIONS: Providing data from a large contemporary multi-institutional patient cohort from high-volume and low-volume institutions, our results reflect the current standard of care in middle Europe. We indicate that the penoscrotal approach is an independent risk factor for increased short-term explantation rates.

In the acute diagnostics of a suspected nephroureterolithiasis, ultrasonography should be the examination modality of choice. In cases of suspected urolithiasis, unclear flank pain with fever or in cases of a solitary kidney, a noncontrast computed tomography (CT) scan should always subsequently be performed. If the sonography findings are inconclusive in pregnant women a magnetic resonance imaging (MRI) examination can be considered. If there are indications for urinary diversion, a retrograde imaging study should be performed as part of the urinary diversion. This or CT imaging is also suitable for preinterventional imaging before shock wave lithotripsy, percutaneous nephrolithotomy or ureteroscopy. Postinterventional imaging is not always necessary and sonography is often sufficient. In a conservative treatment approach an abdominal plain Xray can be used for follow-up assessment.

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.
RESUMO
A fundamental understanding of the physical properties is necessary for the application of lasers in medicine in order to be able to understand and appreciate the biological effect. The most important parameters are emission mode, wavelength of the laser and power output measured in watts. Pulsed lasers can be used for the treatment of stones and soft tissues, whereby in urology this essentially applies to the prostate gland and to a lesser extent also for the ureter, urethra, bladder and kidneys.

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.
RESUMO
PURPOSE: The aim was to study the correlation between cuff size and outcome after implantation of an AMS 800 artificial urinary sphincter. METHODS: A total of 473 male patients with an AMS 800 sphincter implanted between 2012 and 2014 were analyzed in a retrospective multicenter cohort study performed as part of the Central European Debates on Male Incontinence (DOMINO) Project. RESULTS: Single cuffs were implanted in 54.5% and double cuffs in 45.5% of the patients. The cuffs used had a median circumference of 4.5 cm. Within a median follow of 18 months, urethral erosion occurred in 12.8% of the cases and was associated significantly more often with small cuff sizes (P<0.001). Multivariate analysis showed that, apart from cuff size (P=0.03), prior irradiation (P<0.001) and the penoscrotal approach (P=0.036) were associated with an increased erosion rate. Continence rate tended to be highest with median cuff sizes (4-5.5 cm). CONCLUSION: Apart from irradiation and the penoscrotal approach, small cuff size is a risk factor for urethral erosion. Results are best with cuff sizes of 4.5-5.5 cm.
RESUMO
PURPOSE: To analyze perioperative complications and postoperative explantation rates for selected readjustable male sling systems and the perineal single-cuff artificial urinary sphincter (AUS) in a large, contemporary, multi-institutional patient cohort. METHODS: Two hundred eighty-two male patients who underwent implantation between 2010 and 2012 in 13 participating institutions were included in the study (n=127 adjustable male sling [n=95 Argus classic, n=32 Argus T], n=155 AUS). Perioperative characteristics and postoperative complications were analyzed. The explantation rates of the respective devices were assessed using the Fisher exact test and the Mann-Whitney U-test. A Kaplan-Meier curve was generated. Potential features associated with device explantation were analyzed using a multiple logistic regression model (P<0.05). RESULTS: We found significantly increased intraoperative complication rates after adjustable male sling implantation (15.9% [adjustable male sling] vs. 4.2% [AUS], P=0.003). The most frequent intraoperative complication was bladder perforation (n=17). Postoperative infection rates did not vary significantly between the respective devices (P=0.378). Device explantation rates were significantly higher after AUS implantation (9.7% [adjustable male sling] vs. 21.5% [AUS], P=0.030). In multivariate analysis, postoperative infection was a strong independent predictor of decreased device survival (odds ratio, 6.556; P=0.001). CONCLUSIONS: Complication profiles vary between adjustable male slings and AUS. Explantation rates are lower after adjustable male sling implantation. Any kind of postoperative infections are independent predictors of decreased device survival. There is no significant effect of the experience of the implanting institution on device survival.
RESUMO
OBJECTIVE: To investigate the impact of the antibiotic coating InhibiZone on the infection and explantation rates of the AMS 800 in comparison to the AMS 800 without InhibiZone. MATERIALS AND METHODS: We retrospectively identified 305 patients with an AMS 800 in a multicenter cohort study. Patients were subsequently divided into InhibiZone and without InhibiZone-coated groups. Infection and explantation rates were analyzed by univariate and consecutively by multivariate logistic regression adjusted to variable risk factors. The infection-free interval was estimated by Kaplan-Meier plot and compared by the log-rank test. A P value below .05 was considered statistically significant. RESULTS: We identified 47 patients with InhibiZone and 258 without InhibiZone coating. In univariate analysis, we could not identify a significant difference in infection (P = .932) or explantation (P = .715) rates between the groups. In multivariate analysis, impaired wound healing (P = .008) and urethral erosion (P < .001) were independent predictors for infection. The InhibiZone coating neither demonstrated significant influence on the infection rate (P = .534) nor on the explantation rate (P = .214). There was no significant difference in estimated infection-free survival between the groups (P = .265). CONCLUSION: The antibiotic coating of the AMS 800 had no significant impact on infection or explantation rates in our cohort.
