Abstract
Synthetic male sling (MS) is considered an effective surgical treatment to restore male stress urinary incontinence. The modern MS can be categorised into adjustable or non-adjustable types, while the surgical techniques can be divided into retropubic or transobturator approaches. This narrative review paper evaluates the contemporary MS devices in the current commercial market regarding clinical outcomes and refinements in surgical techniques. Scientific advances in device design and technology, coupled with further surgical refinements will enhance the clinical outcomes and improve the safety profile of MS surgery. The newer generation of modern MS not only provides direct compression of the bulbar urethra but also allows for proximal urethral relocation by realigning the mobile sphincter complex to provide further urethral sphincter complex coaptation. Strict patient selection, use of MS with proven clinical records, adherence to safe surgical principles and judicious postoperative care are critical to ensure a high continence rate, good patient satisfaction and low postoperative complications.

Abstract
Prostate cancer is the second most common cancer in men worldwide. Radical prostatectomy and radiation beam therapy are the most common treatment options for localized prostate cancer and have different associated complications. The etiology of post prostatectomy incontinence is multifactorial. There is evidence in the literature that anatomic support and pelvic innervation are important factors in the etiology of post-prostatectomy incontinence. Among the many surgical and technical factors proposed in the literature, extensive dissection during surgery, damage to the neurovascular bundle and the development of postoperative fibrosis have a substantial negative impact on the continence status of men undergoing RP. Sparing of the bladder neck and anterior, and possibly posterior, fixation of the bladder-urethra anastomosis are associated with better continence rates. Overactive bladder syndrome (OAB) is multifactorial and the exact role of prostate surgery in the development of OAB is still under debate. There are several variables that could contribute to detrusor overactivity. Detrusor overactivity in patients after radical prostatectomy has been mainly attributed to a partial denervation of the bladder during surgery. However, together with bladder denervation, other hypotheses, such as the urethrovesical mechanism, have been described. Although there is conflicting evidence regarding the importance of conservative treatment after post-prostatectomy urinary incontinence, pelvic floor muscle training (PFMT) is still considered as the first treatment choice. Duloxetin, either alone or in combination with PFMT, may hasten recovery of urinary incontinence but is often associated with severe gastrointestinal and central nervous side effects. However, neither PFMT nor duloxetine may cure male stress urinary incontinence. The therapeutic decision and the chosen treatment option must be individualized for each patient according to clinical and social factors. During the recent years, the development of new therapeutic choices such as male sling techniques provided a more acceptable management pathway for less severe forms of urinary incontinence related to radical prostatectomy. Following this perspective, technological improvements and the emergence of new dedicated devices currently create the premises for a continuously positive evolution of clinical outcomes in this particular category of patients.

Casteleijn NF, Cornel EB. Argus-T adjustable male sling: A follow-up study on urinary incontinence and patient's satisfaction. Neurourol Urodyn 2021; 40:802-809. [PMID: 33527521 DOI: 10.1002/nau.24619] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2020] [Revised: 01/12/2021] [Accepted: 01/13/2021] [Indexed: 11/09/2022]
Abstract
AIMS The use of Argus-T adjustable sling may be a promising alternative option for the treatment of urinary incontinence after radical prostatectomy, however long-term data is lacking. The aim of this study is to evaluate the long-term results of the Argus-T sling on incontinence rates, patient's quality of life and tape-related complications. METHODS Patients were eligible if persistent stress incontinence was present ≥12 months after radical prostatectomy. Measurements included 24 h frequency volume micturition list, 24 h pad test, 24 h pad count and quality of life questionnaires. Argus-T adjustable sling was placed with a single perineal route incision approach. RESULTS Seventy-eight patients were included, 69 ± 6 years, pre-intervention 24 h urinary loss 212 (75-385) g. Directly after surgery, 63.6% of the patients was completely dry, 79.2% of the patients reported greater than 90% improvement of their urinary loss and 92.2% > 50% improvement. Median follow-up time was 3.2 (2.5-6.1) years. After 5 years of follow-up, 53.3% of the patients were completely dry, 71.5% reported an improvement greater than 90% and 79.6% reported an improvement of greater than 50%. Patients with preoperative urinary loss less than 250 g reported significantly higher improvement of their urinary loss compared to patients with urinary loss ≥250 g (p = .02). Patients satisfaction was still increased after 5 years follow-up (70 ± 21 vs.16 ± 9, p < .001) and patients quality of life remained high (85 ± 20 vs. 88 ± 13, p = .1). Complications were mainly observed directly after surgery. Two patients (2.6%) needed reimplantation of the sling. CONCLUSION These data indicate that Argus-T sling is an effective treatment option in obtaining substantial long-term incontinence relief in patients with invalidating moderate stress urinary incontinence after radical prostatectomy.

Multicentered Assessment of Clinical Outcomes and Factors Associated With Failure of the Adjustable TransObturator Male System (ATOMS). Urology 2020; 148:280-286. [PMID: 33181122 DOI: 10.1016/j.urology.2020.09.045] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2020] [Revised: 09/02/2020] [Accepted: 09/09/2020] [Indexed: 10/23/2022]
Abstract
OBJECTIVE To assess postoperative outcomes from the Adjustable TransObturator Male System (ATOMS) and identify factors influencing failure to achieve continence. PATIENTS AND METHODS A multicentered analysis was performed on all patients treated for postprostatectomy incontinence using the third-generation ATOMS at 9 Canadian tertiary referral centers. The primary outcome was continence (defined as requiring ≤1 pad postoperatively for patients requiring ≥2 pads preoperatively and 0 pads for those requiring 1 pad preoperatively). Secondary outcomes included improvement (>50% change in pad use), patient satisfaction, explantation, and postoperative complications. RESULTS Two hundred and eighty nine patients with a mean age of 68.9 years were analyzed. Pre-operatively mean pad per day use was 4.2 (1-12), 31.5% of patients reported severe incontinence (≥5 pads/day), 33.9% had concurrent radiotherapy and 19.4% had failed previous incontinence surgery. Overall continence rate was 73.3% (n = 212) at a mean follow-up of 19.6 months. More than eighty nine percent (89.3%) (n = 258) of patients experienced >50% improvement, 84.4% (n = 244) of patients were satisfied with the results of surgery. More than seven percent (7.9%) (n = 23) required device explantation. On multivariate Cox regression analysis, concurrent radiotherapy (hazard ratio [H.R.] 2.3, P < .001), diabetes (H.R. 2.2, P = .007) and increased pre-operative pad usage (H.R. 1.1, P = .02) were each associated with failure to achieve continence, while patient age (P = .60), obesity (P = .08), prior urethral stenosis (P = .56), and prior incontinence surgery (P = .13) were not. Radiation therapy was also associated with device explantation (H.R. 2.7, P = .02). CONCLUSION ATOMS is a safe and efficacious for treatment of postprostatectomy incontinence. However, patients with prior radiation, increased pre-operative pad use, or diabetes are less likely to achieve continence.

Abstract
Urinary incontinence after prostatectomy has a significant negative impact on the quality of life of the patient. The surgical treatment includes several models of male slings, such as adjustable slings. The objective of this study was to evaluate the effectiveness and safety of adjustable sling in the treatment of post-prostatectomy urinary incontinence. This is a systematic review of literature. The following electronic databases were searched until January 2018: PubMed®, Embase, CENTRAL and LILACS. The keywords used in the search strategies were: "prostatectomy" [Mesh], "urinary incontinence" [Mesh] and "suburethral slings" [Mesh]. Randomized clinical trials and observational studies, with or without Control Group, and follow-up of more than 12 months were included. Only one randomized study with high risk of bias was included and it concluded the effectiveness equivalence between adjustable and non-adjustable slings. All other studies were cases series with patients of varying levels of incontinence intensity and history of pelvic radiation therapy and previous surgeries. The meta-analysis for 0 pad in 24 hours demonstrated an effectiveness of 53%. For the 0 to 1 pad test in 24 hours, the meta-analysis resulted in an effectiveness of 69%. Risk factors for surgery failure include prior radiation, severity of post-prostatectomy urinary incontinence, and previous surgeries. The meta-analysis of the extrusion rate was 9.8% and the most commonly reported adverse effects were pain and local infection. Evidence of low quality indicates that adjustable slings are effective for treating post-prostatectomy urinary incontinence, with frequency of adverse events similar to the surgical option considered gold standard (the artificial urinary sphincter implant).

Abstract
CONTEXT Male slings are recommended by the European Association of Urology guideline for the treatment of mild to moderate postprostatectomy incontinence. However, none of them has been proved to be superior to the others, and there are no defined guidelines to preference of a given sling model. OBJECTIVE To evaluate and compare the efficacy and safety of the different types of male slings in the treatment of postprostatectomy incontinence. EVIDENCE ACQUISITION This systematic review and meta-analysis was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-analysis statement. A systematic literature search in the databases of PubMed, Embase, and Cochrane using the keywords "incontinence," "prostatectomy," and "male sling/system" was conducted in June 2018. Studies in English with at least 15 patients and a minimum follow-up of 12 mo were included. As the primary endpoint, we assessed the cure rate of the different sling types. As secondary endpoints, we assessed the improvement rate, subjective cure rate, overall complication rate, explantation rate, risk factors for failure, and effect on patients' quality of life. EVIDENCE SYNTHESIS The literature search identified 833 articles. A total of 64 studies with 72 patient cohorts were eligible for inclusion. Fixed slings were implanted in 55 (76.4%) of the patient cohorts. The objective cure rate varies between 8.3% and 87% (pooled estimate 0.50, 95% confidence interval [CI] 0.45-0.56, I2=82%). Subjective cure was achieved in 33-94.4%. Adjustable slings showed objective cure rates between 17% and 92% (pooled estimate 0.61, 95% CI 0.51-0.71, I2=88%). The subjective cure rate varies between 28% and 100%. In both types of slings, pain was the most common complication, but chronic painful conditions were really rare (1.3% in fixed slings and 1.5% in adjustable slings). The most common complication after pain was urinary retention in fixed slings, and infection and consequential explantation in adjustable slings. CONCLUSIONS Both fixed and adjustable slings are beneficial for the treatment of postprostatectomy incontinence. Although adjustable slings might lead to higher objective cure rates, they might be associated with higher complication and explantation rates. However, at present, due to significant heterogeneity of the data, this cannot be said with certainty. More randomized controlled trials with long-term follow-up and the same definition for continence are needed. PATIENT SUMMARY Fixed and adjustable slings are effective treatment options in mild to moderate postprostatectomy incontinence.

Abstract
Male stress urinary incontinence (SUI) remains a debilitating condition that adversely impacts all domains of quality of life and is associated with significant social stigma and health economic burden. The incidence of post-prostatectomy urinary incontinence (PPI) depends on the definition of urinary incontinence and the length of patient follow up. In patients with persistent PPI following failure of conservative measures, surgical treatment is recommended although there is no published guideline on when surgery should be performed, and what the best surgical option is. Male slings (MS) can be divided into adjustable or non-adjustable types, and offers an attractive option for patients who wish to avoid mechanical handling during urinary voiding. Published intermediate data supports good safety and efficacy rate in men with mild to moderate degree of SUI. The AMS 800 artificial urinary sphincter (AUS) remains the standard of treatment for complete continence and has the longest efficacy and safety records. Other AUS-like devices are designed to address current AMS 800 limitations but themselves are fraught with their own issues.

Abstract
OBJECTIVE To evaluate the long-term effectiveness and safety of the adjustable transobturator male system (ATOMS® , Agency for Medical Innovations A.M.I., Feldkirch, Austria) in a European-wide multicentre setting. PATIENTS AND METHODS In all, 287 men with stress urinary incontinence (SUI) were treated with the ATOMS device between June 2009 and March 2016. Continence parameters (daily pad test/pad use), urodynamics (maximum urinary flow rate, voiding volume, residual urine), and pain/quality of life (QoL) ratings (visual analogue scale/Leeds Assessment of Neuropathic Symptoms and Signs, International Consultation on Incontinence Questionnaire-Short Form [ICIQ-SF]/Patient Global Impression of Improvement [PGI-I]) were compared preoperatively and after intermediate (12 months) as well as after individual maximum follow-up. Overall success rate, dry rate (<10 mL/day and 0-1 pad/day), device durability, treatment failure, and device complications were recorded. Nonparametric tests were used for statistical analyses. RESULTS After a median (interquartile range [IQR]) follow-up of 31 (10-54) months and a median (IQR) of 3 (2-4) adjustments, the overall success rate was 90% (258 men) and the dry rate was 64% (184). Daily pad test and pad use decreased from a median of 400 mL/day and 4 pads/day to a median of 18 mL/day and 1 pad/day (both P < 0.001), concomitantly QoL ratings significantly improved and changed to a high level of satisfaction (PGI-I 4 to 2, ICIQ-SF 17 to 5; both P < 0.001). The UI results at 12 months were comparable to those at final follow-up. Chronic pain and intraoperative complications did not occur. Most of the postoperative complications were Clavien-Dindo grade I-III (no grade IV or V). At present, 231 (80%) of all the ATOMS devices are still functioning; 56 (20%) were removed, the most common reason being local titanium intolerance (41%) and leak/dysfunction (30%). The operating time and continence outcome varied between port generations. In this regard the latest port generation (silicone-covered scrotal port) was superior to its predecessors. Primary implantation (P = 0.002), good physical health (P = 0.001), and no history of radiotherapy (P < 0.001) were prognostic factors for beneficial treatment outcome. CONCLUSION The ATOMS device is safe and shows high treatment efficacy and patient satisfaction in the largest cohort study to date. The latest generation, with its pre-attached silicone-covered scrotal port, is superior to its predecessors. Significantly better results were achieved with primary implantation and in those without a history of radiotherapy.
