RESUMO

OBJECTIVE: To assess changes in voiding phase, especially urethral resistance after post-prostatectomy urinary incontinence (PPI) treatment with the Adjustable TransObturator Male System (ATOMS). MATERIAL AND METHODS: A longitudinal prospective study was performed on 45 men treated with ATOMS for PPI, with the intention to evaluate the changes produced by the implant on the voiding phase. Patients with preoperative urodynamic study were offered postoperative urodynamic evaluation, and both studies were compared. The following urodynamic date were evaluated: maximum voiding detrusor pressure, detrusor pressure at maximum flow rate, maximum flow rate (Qmax), voiding volume, post-void residue, bladder outlet obstruction index (BOOI), urethral resistance factor (URA), and bladder contractility index (BCI). The statistical analysis used were the mean comparison test for dependent groups (Student's t test) for parametric variables and the Wilcoxon test for non-parametric variables. The signification level was set at 95% bilateral. RESULTS: A total of 37 patients (82.2%) used zero pads/day at the time of urodynamic postoperative evaluation and pad-test evolved from 592 ± 289 ml baseline to 25 ± 40 ml (p = 0.0001). Significant differences were observed in Qmax (15 ± 8.3 before and 11 ± 8.3 after surgery; p = 0.008), voiding volume (282 ± 130.7 before and 184 ± 99.92 after surgery). BOOI (-12 ± 23.9 before and -2 ± 21.4 after surgery; p = 0.025) and BCI (93 ± 46.4 before and 76 ± 46.0 after surgery; p = 0.044). In no case did we observe postoperative bladder outlet obstruction, according to URA parameter below 29 cm H2 O in all cases. There was not a significant variation either in post-void urinary residual volume (15 ± 47.4 before and 14 ± 24.2 after surgery, p = 0.867). CONCLUSIONS: The ATOMS implant induces a decrease of Qmax, voided volume, and bladder contractility and an increase of BOOI. However, our findings suggest that ATOMS device does not cause bladder outlet obstruction.

RESUMO

OBJECTIVE: To assess the efficacy and safety of Adjustable Transobturator Male System (ATOMS) compared to male Readjustment Mechanical External (REMEEX) system for post-prostatectomy incontinence (PPI). MATERIAL AND METHODS: A systematic review and meta-analysis on adjustable device ATOMS compared to male REMEEX is presented. Studies on female or neurogenic incontinence were excluded. Primary objectives were evaluation of dryness (the proportion of patients with no-pad or one safety pad/day after device adjustment) and improvement between devices. Secondary objectives were complications and explant rate. They were estimated using a random-effect model. Statistical heterogeneity among studies was assessed using Cochran's Q test, Higgins's I2 statistics and tau2. RESULTS: Combined data of 29 observational studies with 1919 patients showed an equivalent proportion of patients treated with radical prostatectomy (p = .125) and previous radiation (p = .126). Dryness rate was 69.3% for ATOMS and 53.4% for male REEMEX (p = .008). Improvement rate was 90.8% for ATOMS and 80.2% for REMEEX (p = .007). Complication rate was 18.9% for ATOMS and 35.8% for REMEEX (p = .096) and explant rate was 5.5% for ATOMS and 13.9% for REMEEX (p = .027). Significant heterogeneity was evidenced, due to absence of randomized studies, variable incontinence severity baseline, difficulties for a common reporting of complications and difference in the follow-up. Differences observed between devices remained statistically significant when only studies with silicone-covered scrotal port (SSP) ATOMS and male REMEEX system II were considered. CONCLUSIONS: Despite the absence of direct comparison and the limitations observed ATOMS appears more effective than male REMEEX to treat PPI, and with less explant rate as reported in the literature.

RESUMO

PURPOSE: To evaluate efficacy of urorectal fistula (URF) repair using different approaches and the clinical factor determinant of success, and also the morbidity associated to the procedure and health-related quality of life (HRQoL) in male survivors of pelvic malignancies. MATERIAL AND METHODS: Retrospective evaluation of 39 patients with URF primarily intervened in three institutions using different surgical approaches. Success was defined as effective fistula closure. Variables evaluated included demographics, previous treatments, surgical approach, ancillary surgeries, complications and HRQoL by using a standardized non-validated specific questionnaire. Median follow-up from surgery to interview was 55 months (interquartile range 49, range 4-112). Factors determinant of success were investigated using logistic regression. Safety of the procedure was evaluated by Clavien-Dindo scale. Deterioration of continence and erectile function and other HRQoL issues were evaluated. RESULTS: Prostate cancer treatment was the predominant etiology. The success rate for fistula repair was 89.5%. The surgical approach was not related to failed repair (p=0.35) or complications (p=0.29). Factors associated with failure were complications (p=0.025), radiotherapy (p=0.03), fistula location (p=0.04) and fistula size (p=0.007). Multivariate analysis revealed fistula size was the only independent determinant of failure (OR 6.904, 1.01-47.75). Complications occurred in 46.2% and severe complications in 12.8%. The mortality related to the procedure was 2.6%. Urinary incontinence was present before repair in 26.3% and erectile dysfunction in 89.5%. Fistula repair caused de novo urinary incontinence in 7.9% and deterioration of erectile status in 44.7%. Globally 79% were satisfied after repair and only 7.9% rated HRQoL as unhappy. Trans-sphincteric approach was related to less deterioration of erectile function (p=0.003), and higher perceived satisfaction in QoL (p=0.04). CONCLUSIONS: The surgical approach elected to correct URF is not determinant of success nor of complications. Fistula size appears as independent determinant for failure. Trans-sphincteric approach could be advantageous over other procedures regarding HRQoL issues.

RESUMO

OBJECTIVE: To evaluate whether urodynamic voiding risk factors can be predictive of failure of postprostatectomy urinary incontinence (PPI) treatment with adjustable transobturator male system (ATOMS). MATERIALS AND METHODS: We carried out a longitudinal study on 77 males treated for PPI with ATOMS. Patients were submitted preoperatively to a urodynamic study. The postoperative outcome was checked by pad-test. Treatment success was defined as daily pad-test below 10 mL. Statistical analysis used were Fisher exact test, χ2 lineal by lineal test, Student t test, and logistic regression analysis. The signification level was set at 95% bilateral. RESULTS: Treatment was successful in 54 patients (70%) achieving continence. The urodynamic parameters that related to postoperative continence outcome were the cystometric bladder capacity (direct relationship with continence (P = .019), type of voiding (more probability to achieve continence in patients who voided voluntarily followed by patients with involuntary voiding and abdominal straining voiding) (P = .034), Bladder Outlet Obstruction Index (BOOI) (inversely related with continence) (P = .025), and maximum voiding abdominal pressure (inversely related with continence) (P = .049). Multivariate analysis showed that cystometric bladder capacity (odds ratio [OR], 1.01; confidence interval [CI], 1.02-1.00), BOOI (OR, 0.97; CI, 0.99-0.94), and maximum abdominal bladder pressure (OR, 0.97; CI, 0.98-0.94) were independent risk factors to predict treatment success after ATOMS implant. CONCLUSIONS: The study of functional voiding parameters is useful to know the risk factors that influence postoperative outcome of PPI with ATOMS device. These findings could be of primary importance to facilitate optimum patient selection for this implant and therefore improve operative results.

RESUMO

AIM: The aim of this study is to evaluate long-term durability and effectiveness of the adjustable transobturator male system (ATOMS). MATERIALS AND METHODS: The retrospective multicenter Iberian ATOMS study (n = 215) was updated to evaluate long-term continence status, complications, explants, and secondary treatments. Mean follow-up from surgery to March 2020 was 60.6 ± 18.4 months (range, 39-91). Eleven patients deceased of an unrelated causes. Kaplan-Meier curves were performed to evaluate device durability and incontinence free of recurrence interval. The multivariate analysis defined the population at risk of device explant. RESULTS: A total of 155 patients were dry at the last follow-up visit (72.1%); 99 (46%) used no pads and 56 (26%) used a security pad/day with urine loss less than 10 mL; 96% of dry patients after adjustment remained free of incontinence 1 year later, 93.6% 2 years later, 91.1% 3 years later, 89.2% 5 years later, and 86.7% 8 years later. Complications during follow-up occurred in 43 of 215 (20%). In total, 25 (11.6%) devices were explanted and causes were inefficacy 11 (44%), inefficacy and pain 3 (12%), port erosion 10 (40%), and wound infection 1 (4%). The secondary implant was performed in 11 (5.1%) cases, 6 artificial urinary sphincter and 5 repeated ATOMS. Time to explant was associated to complications (P < .0001), baseline stress urinary incontinence (SUI) severity (P = .01), and former irradiation (P = .03). Multivariate analysis revealed complications (hazard ratio [HR] = 8.71; 3.83-19.82), baseline SUI severity (>5 compared to 1-2 pads/day; HR = 14.9; 1.87-125), and irradiation before ATOMS (HR = 2.26; 1.02-5.18) predicted earlier ATOMS explant. Three cases received radiation after implant without complication. CONCLUSIONS: ATOMS device is efficacious and safe in the long term. Determinants for device explant include complications, baseline severity of incontinence, and previous irradiation. Currently, the durability of the device after 5 years is reassuring.

RESUMO

BACKGROUNDS: Patient-reported outcome measurements are important for urinary incontinence. We analyze self-assessed patient satisfaction and define the clinical profile of patient with highest satisfaction with the adjustable transobturator male system (ATOMS). METHODS: Patient perception of results was evaluated in a series of 181 patients after ATOMS adjustment. Baseline incontinence severity was defined in pads-per-day (PPD) as mild (2), moderate (3-5) or severe (≥ 6), and dryness as use of none or one security PPD. Post-operative pain at discharge was evaluated by 0-10 visual analogue scale and complications by Clavien-Dindo classification. Multivariate analysis was performed to anticipate "very much better" than baseline perception on patient global impression of improvement and a predictive nomogram was developed. RESULTS: Dryness was achieved in 80.7% (94.9% mild, 80.8% moderate and 65.8% severe groups). Mean pad-test and pad-count decrease with respect to baseline was 458 ± 330 ml and 3.2 ± 1.9 PPD, respectively (both p < .0001). Complications presented in 25 (13.8%). The proportion of patients that self-declared satisfied with the procedure was 87.1%; 90.6% perceived their situation "better" and 48.1% "very much better" than before. Multivariate analysis revealed best perception is defined by dryness after adjustment (p < .0001), baseline severity of incontinence (p = .007), low post-operative pain at discharge (p = .0018) and lack of complications (p = .007). CONCLUSIONS: Self-assessed satisfaction with ATOMS is very high. Factors that predict best perception of improvement include dryness, baseline SUI severity, presence of complications and pain level during admission. Radiotherapy and device generation were not independent predictors. A nomogram to predict patients that are completely satisfied with ATOMS after adjustment is proposed.

RESUMO

AIM: To evaluate effectiveness and safety of the adjustable transobturator male system (ATOMS) for male stress urinary incontinence (SUI). MATERIAL AND METHODS: A retrospective multicenter study was conducted in nine Iberian institutions using a board-approved database for 215 patients intervened between 2012 and 2017, with no case excluded. Continence status, patient satisfaction, number, and grade of complications (Clavien-Dindo) and factors affecting dry rate at adjustment were evaluated. Multivariate analysis defined the population at best success rate. Incontinence recurrence due to device failure and/or explant was evaluated and Kaplan-Meier curve for durability performed. RESULTS: Adjustment was achieved at a mean 1.4 ± 1.9 fillings. Dry-rate after adjustment was 80.5% (96.2% mild and 75.3% moderate-severe), 121 (56.3%) used no pads, and 52 (24.2%) a security pad with urine loss under 10 mL. Mean basal daily pad-test and pad-count decreased from 484 ± 372.3 mL and 3.9 ± 2 pads to 63.5 ± 201.2 mL and 0.9 ± 1.5pads (both P < 0.0001). Satisfaction rate was 85.1% (94.3% mild and 82.1% moderate-severe). Factors associated to dryness were: lesser severity of SUI (P < .0001), absence of radiotherapy (P = 0.0002) and device generation (P = 0.05). Multivariate analysis revealed absence of radiation (OR = 3.12; 1.36-7.19), mild (OR = 19.61; 3.95-100), and moderate (OR = 2.48; 1.1-5.59) SUI were independent predictors. Complications presented in 33(15.35%); 66.7% grade 1, 9.1% grade 2, and 24.2% grade 3. At 24.3 ± 15 mo mean follow-up device was explanted in seven (3.25%) and SUI worsened after adjustment in nine (4.2%). Dry-rate at follow-up was 73% and durability of device in dry patients at adjustment was 89.8% (82.9-94) at 2-years. CONCLUSIONS: This study confirms ATOMS device is safe and achieves high treatment efficacy and patient satisfaction in a multicenter setting. Significantly better results are achieved in less severe and non-irradiated cases. Durability of the device is reassuring in the short-term.

RESUMO

OBJECTIVES: Feasibility study to evaluate the efficacy and safety of Adjustable Transobturator Male System (ATOMS) after failed surgical devices for male stress urinary incontinence (SUI). MATERIALS AND METHODS: Thirty patients were implanted with ATOMS after they were implanted with surgical device/s previously. SUI severity was evaluated as dryness (0-1 pad/day), mild (2 pads/day), moderate (3-5 pads/day), or severe (≥6 pads/day). Change in pad-test and pad-count after adjustment, operative parameters, patient satisfaction, and number and grade of complications were investigated. RESULTS: Previous failed treatment methods were artificial urinary sphincter (AUS; n = 19), Advance (n = 10), and Virtue (n = 1). Six cases had multiple previous treatments. Preoperative SUI was mild 6 (20%), moderate 11 (36.7%), and severe 13 (43.3%). Median pad-test decreased from 435 mL baseline to 10 mL after adjustment and pad-count from 4 to 0. Dry-rate was 76.7 and 83.3% declared satisfied. Postoperative SUI distribution was mild in 3 (10%) and moderate in 4 (13.3%). No patient had urinary retention after catheter removal. Complications presented in 4 (13.3%; 3 grade-I, 1 grade-II). After a median of 24 months follow-up, no system experienced infection or urethral erosion and 1 (3.3%) was removed for inefficacy. CONCLUSION: Based on short-term efficacy and patient satisfaction, ATOMS can be a realistic alternative for male SUI after other failed systems, including AUS. The absence of urethral erosion and limited infective problems makes this alternative attractive for cases with previous failed treatments.

RESUMO

Bladder pain syndrome/interstitial cystitis (BPS/IC) is a chronic disease characterised by persistent irritating micturition symptoms and pain. The objective was to compare the clinical efficacy of currently available products for intravesical therapy of BPS/IC and to assess their pharmacoeconomic impact. A Pubmed/Medline database search was performed for articles on intravesical therapy for BPS/IC. A total of 345 publications were identified, from which 326 were excluded. Statistical evaluation was performed with effect size (ES) assessment of symptom reduction and response rates. The final set of 19 articles on intravesical BPS/IC therapy included 5 prospective controlled trials (CTs), the remaining were classified as uncontrolled clinical studies. The total number of patients included was 801, 228 of whom had been evaluated in a CT. For CTs, the largest ES for symptom reduction as well as response rate was observed for high molecular weight hyaluronic acid (HMW-HA), with similar findings in two uncontrolled studies with HMW-HA. The number needed to treat to achieve a response to intravesical therapy was 2.67 for intravesical pentosan polysulphate and 1.31 for HMW-HA which were superior to all other instillates. HMW-HA was significantly superior in cost effectiveness and cost efficacy to all other instillation regimes. The present meta-analysis combined medical and pharmacoeconomic aspects and demonstrated an advantage of HMW-HA over other instillation agents; however, direct comparisons between the different products have not been performed to date in properly designed controlled studies.

RESUMO

OBJECTIVES: We compared perioperative results and complications of reconstructive surgery of the urinary tract performed using a multichannel platform through the umbilicus and one additional 3.5-mm with a cohort of patients simultaneously treated with conventional 4-port laparoscopy. MATERIALS AND METHODS: Matched-pair study comparing perioperative outcomes, postoperative visual analogue pain scale (VAPS) and morbidity of 2-port (n = 20) and 4-port (n = 10) laparoscopic reconstructive urological surgery. Preoperative and perioperative data compared included demographics, type of surgery, operative time, blood loss, decrease in serum hemoglobin, operative complications, length of stay and postoperative complications according to Clavien-Dindo classification. RESULTS: There was no significant difference between groups regarding age, gender, body mass index, American Society of Anesthesiologists score, type of surgery, operative time, operative complications and intraoperative or postoperative transfusion. Estimated blood loss was lower using reduced-port approach. VAPS at postoperative day one was significantly lower for 2-port approach and so was the length of stay. Patient satisfaction with the wound was higher for 2-port surgery. Differences were not observed in number and severity of postoperative complications. CONCLUSIONS: Urological reconstructive operations can be safely performed using the hybrid laparoendoscopic single-site umbilical approach, resulting in lower blood loss, higher patient satisfaction and lower postoperative pain, which also facilitate earlier hospital discharge, than the same reconstructive procedures performed through multiport conventional laparoscopy.

RESUMO

(1) Background: The adjustable trans-obturator male system (ATOMS) is a surgical device developed to treat post-prostatectomy incontinence (PPI) after prostate cancer treatment. We review the current literature on this anti-incontinence device with the intention of assessing the effectiveness, safety and duration of the silicone-covered scrotal port (SSP) ATOMS, the only generation of the device that is currently available. (2) Material and Methods: Non-systematic literature review is performed. Forty-eight full-text articles are assessed for eligibility. Case reports, expert opinions or commentaries without specific data reported (n = 6), studies with patients who underwent intervention before 2014 (IP or SP ATOMS; n = 10), and studies with incontinence after transurethral resection of the prostate (TUR-P; n = 2) are excluded for analysis. Thirty studies with SSP ATOMS are included in a qualitative synthesis that incorporates systematic reviews (n = 3), articles partially overlapping with other previously published studies (e.g., follow-up or series updates; n = 9), and studies focusing on specific populations (n = 8). Only articles revealing outcomes of SSP ATOMS were included in the quantitative synthesis of results (n = 10). (3) Results: the pooled data of 1515 patients from the 10 studies with SSP ATOMS confirmed very satisfactory results with this device after adjustment: dry rate: 63-82%, improved rate: 85-100%, complication rate: 7-33%, device infection rate: 2.7-6.2% and explant rate: 0-19%. The durability of the device is reassuring, with 89% of devices in place 5 years after implantation. (4) Conclusion: Despite the absence of randomized controlled studies, the literature findings confirm results of SSP ATOMS appear equivalent to those of artificial urinary sphincters (AUSs) in terms of continence, satisfaction and complications, but with a lower rate of revision in the long-term. A prospective study identified that patients with daily pad test results <900 mL and a Male Stress Incontinence Grading Scale (MSIGS) of not 4 (i.e., early and persistent stream or urine loss) are the best candidates. Future studies centered on the elder population at higher risk of impaired cognitive ability and in patients including radiation as prostate cancer treatment are needed.

RESUMO

We aimed to determine the risk factors for postoperative overactive bladder (OAB) in patients treated with an adjustable trans-obturator male system (ATOMS) for stress incontinence after radical treatment of prostate cancer. A prospective study was performed on 56 patients implanted with an ATOMS for PPI. Clinical and urodynamic information was recorded before and after ATOMS implantation. We built a multivariate model to find out the clinical and urodynamic factors that independently influenced postoperative OAB and the prognostic factors that influenced the efficacy of medical treatment of OAB. We found that the clinical risk factors were the preoperative intensity of urinary incontinence (number of daily pads used and amount of urinary leakage), International Consultation on Incontinence Questionnaire (ICIQ) score, postoperative number of ATOMS adjustments, final cushion volume, and incontinence cure. The urodynamic data associated with OAB were cystometric bladder capacity, voided volume, volume at initial involuntary contraction (IC), maximum flow rate, bladder contractility index (BCI), and urethral resistance (URA). The prognostic factors for the efficacy of oral treatment of OAB were the volume at the first IC (direct relationship) and the maximum abdominal voiding pressure (inverse relationship). The multivariate model showed that the independent clinical risk factors were the daily pad count before the implantation and the ICIQ score at baseline and after treatment. The independent urodynamic data were the volume at the first IC (inverse relationship) and the URA value (direct relationship). Both predictive factors of treatment efficacy were found to be independent. Detrusor overactivity plays an important role in postoperative OAB, although other urodynamic and clinical factors such as the degree of urethral resistance and abdominal strength may influence this condition.

RESUMO

(1) Background: Male stress incontinence in patients with previously treated urethral or bladder neck stricture is a therapeutic challenge. The efficacy and safety of the adjustable trans-obturator male system (ATOMS) in these patients is unknown. (2) Methods: All patients with primary ATOMS implants in our institution between 2014 and 2021 were included. The outcomes of patients with previously treated urethral or bladder neck stricture (≥6 months before ATOMS implant) and stable 16Ch urethral caliber were compared to those without a history of stricture. The primary endpoint was the dry patient rate, defined as the pad test ≤ 20 mL/day, and complication rate, including device removal. The secondary variable was self-perceived satisfaction using the Patient Global Impression of Improvement (PGI-I) scale. Wilcoxon rank sum test, Fisher's exact test and logistic regression were performed. (3) Results: One hundred and forty-nine consecutive patients were included, twenty-one (14%) previously treated for urethral or bladder neck stricture (seven urethroplasty, nine internal urethrotomy and five bladder neck incision). After ATOMS adjustment, 38% of the patients with treated stricture were continent compared to 83% of those without (p < 0.0001). After weighted matched observations using propensity score pairing, the proportion of continent patients without a previous stricture was 56% (p = 0.236). Complications occurred in 29% of the patients with stricture and in 20% of those without (p = 0.34). The severity of the complications was distributed evenly among the groups (p = 0.42). Regarding self-perceived satisfaction with the implant, 90% of the patients with stricture perceived the results satisfactorily (PGI-I 1−3) compared to 97% of the rest (p = 0.167). Stricture was associated with radiotherapy (p < 0.0001) and time from prostatectomy to implantation (p = 0.012). There was a moderate correlation between previous stricture and the severity of incontinence, both evaluated according to the 24-h pad test (Rho = 0.378; p < 0.0001) and the ICIQ-SF questionnaire (Rho = 0.351; p < 0.0001). Multivariate analysis for the factors predictive of failure after ATOMS adjustment revealed previous stricture (OR 4.66; 95% CI 1.2−18.87), baseline 24-h pad test (per 100 mL, OR 1.28; 95% CI 1.09−1.52) and final cushion volume (per mL, OR 1.34; 95% CI 1.19−1.55). This model predicted dryness with an AUC of 92%. After the PSMATCH procedure using a propensity score, the model remained unchanged, with the previous stricture (OR 8.05; 95% CI 1.08−110.83), baseline 24-h pad test (per 100 mL, OR 1.53; 95% CI 1.15−2.26) and final cushion volume (per mL, OR 1.45; 95% CI 1.17−2) being independent predictors and an AUC of 93%. (4) Conclusions: ATOMS can be used to treat male stress incontinence in patients with a history of stricture, although the effectiveness of the device is reduced. On the other hand, the security and perceived satisfaction were equivalent for both groups.

RESUMO

INTRODUCTION: A prospective evaluation of outcomes in a series of patients with post-prostatectomy incontinence (PPI) treated with two different devices is presented. METHODS: Consecutive patients with PPI underwent interventions with an adjustable transobturator male system (ATOMS) or artificial urinary sphincter (AUS). Decisions were based on patient preference after physician counselling. Patient characteristics and operative and postoperative parameters including dryness, satisfaction, complications, revision and device durability were evaluated. RESULTS: One hundred twenty-nine patients were included: 102 (79.1%) received ATOMS and 27 (20.9%) AUS. Mean follow-up was 34.9 ± 15.9 months. No difference was observed between patient age (p = 0.56), ASA score (p = 0.13), Charlson index (p = 0.57) and radiation (p = 0.3). BMI was higher for AUS (27.1 vs. 29.7; p = 0.003) and also baseline incontinence severity (7.9% mild, 44.1% moderate and 48% severe for ATOMS vs. 11.1% moderate and 88.9% severe for AUS; p = 0.0007). Differential pad test was higher for AUS (- 470 vs. - 1000 ml; p < 0.0001) and so was ICIQ-SF (15.62 vs. 18.3; p < 0.001), but total dryness (76.5 vs. 66.7%; p = 0.33), social continence (90.2 vs. 85.2%; p = 0.49) and satisfaction (92.2 vs. 88.9%; p = 0.69) were equivalent. The postoperative complication rate was similar (22.6 vs. 29.6%; p = 0.4). The surgical revision rate was higher for AUS (6.9 vs. 22.2%; p = 0.029) and also the explant rate but did not reach statistical significance (4.9 vs. 14.8%; p = 0.09). Time to explant was shorter for AUS (log-rank p = 0.021). Regression analysis revealed radiation (p = 0.003) and incontinence severity (p = 0.029) predict total dryness, while complications (p < 0.005) and type of device (p = 0.039) independently predict surgical revision. CONCLUSIONS: Both ATOMS and AUS are effective devices. Pad test change for AUS exceeds that of ATOMS. The revision rate is higher for AUS, and durability is superior for ATOMS. The satisfaction rate is equivalent. Larger series and longer follow-up are needed to compare both devices more appropriately. According to our experience, the AUS is not the only gold standard for PPI.

RESUMO

(1) Background: To critically evaluate dorsal onlay buccal mucosal graft urethroplasty (DOBMGU) for posterior urethral stenosis repair following transurethral resection and other endoscopic prostate procedures. (2) Methods: A retrospective multi-institutional review of patients with membranous or bulbomembranous urethral stenosis for whom treatment with DOBMGU was conducted after receipt of prostate endoscopic procedures. Baseline data, peri-operative care, post-operative care and patient-reported outcomes were analyzed. The primary outcomes were procedural failure and development of de novo stress urinary incontinence (SUI). The secondary outcomes were changes in voiding, sexual function and patient satisfaction. (3) Results: A total of 107 men with a mean age of 69 ± 9.5 years and stenosis length of 3.5 ± 1.8 cm were included. Prior endoscopic procedures among participants were 47 patients (44%) with monopolar TURP, 33 (30.8%) with bipolar TURP, 16 (15%) with Greenlight laser, 9 (8.4%) with Holmium laser enucleation and 2 (1.9%) with bladder neck incision. At a mean follow-up time of 59.3 ± 45.1 months, stenosis recurred in 10 patients (9.35%). Multivariate analysis confirmed that postoperative complications (OR 12.5; p = 0.009), history of radiation (OR 8.3; p = 0.016) and ≥2 dilatations before urethroplasty (OR 8.3; p = 0.032) were independent predictors of recurrence. Only one patient (0.9%) developed de novo SUI. Patients experienced significant improvement in PVR (128 to 60 cc; p = 0.001), Uroflow (6.2 to 16.8 cc/s; p = 0.001), SHIM (11.5 to 11.7; p = 0.028), IPSS (20 to 7.7; p < 0.001) and QoL (4.4 to 1.7; p < 0.001), and 87 cases (81.3%) reported a GRA of + 2 or better. (4) Conclusions: DOBMGU is an effective and safe option for patients with posterior urethral stenosis following TURP and other prostate endoscopic procedures. This non-transecting approach minimizes external urinary sphincter manipulation, thus limiting postoperative risk of SUI or erectile dysfunction.

RESUMO

BACKGROUND AND PURPOSE: Urinary incontinence is one of the most serious complications of prostate cancer treatment. The objective of this study was to assess efficacy and safety of Adjustable Transobturator Male System (ATOMS) compared to Adjustable Continence Therapy (proACT) for male stress urinary incotinence according to literature findings. MATERIAL AND METHODS: A systematic review and meta-analysis on adjustable devices ATOMS and ProACT is presented. Studies on female or neurogenic incontinence were excluded. Differences between ATOMS and proACT in primary objective: dryness status (no-pad or one safety pad/day) after initial device adjustment, and in secondary objectives: improvement, satisfaction, complications and device durability, were estimated using random-effect model. Statistical heterogeneity among studies included in the meta-analysis was assessed using tau2, Higgins´s I2 statistics and Cochran´s Q test. RESULTS: Combined data of 41 observational studies with 3059 patients showed higher dryness (68 vs. 55%; p = .01) and improvement (91 vs. 80%; p = .007) rate for ATOMS than ProACT. Mean pad-count (-4 vs. -2.5 pads/day; p = .005) and pad-test decrease (-425.7 vs. -211.4 cc; p < .0001) were also significantly lower. Satisfaction was higher for ATOMS (87 vs. 56%; p = .002) and explant rate was higher for proACT (5 vs. 24%; p < .0001). Complication rate for ProACT was also higher, but not statistically significant (17 vs. 26%; p = .07). Mean follow-up was 25.7 months, lower for ATOMS than ProACT (20.8 vs. 30.6 months; p = .02). The rate of working devices favoured ATOMS at 1-year (92 vs. 76; p < .0001), 2-years (85 vs. 61%; p = .0008) and 3-years (81 vs. 58%; p = .0001). Significant heterogeneity was evidenced, due to variable incontinence severity baseline, difficulties for a common reporting of complications, different number of adjustments and time of follow-up and absence of randomized studies. CONCLUSIONS: Despite the limitations that studies available are exclusively descriptive and the follow-up is limited, literature findings confirm ATOMS is more efficacious, with higher patient satisfaction and better durability than ProACT to treat male stress incontinence.

RESUMO

OBJECTIVE: To evaluate the outcomes and factors affecting success of urethroplasty in patients with stricture recurrence after Urolume urethral stent. MATERIAL AND METHODS: This is a retrospective international multicenter study on patients treated with urethral reconstruction after Urolume stent. Stricture and stent length, time between urethral stent insertion and urethroplasty, age, mode of stent retrieval, type of urethroplasty, complications and baseline, and posturethroplasty voiding parameters were analyzed. Successful outcome was defined as standard voiding, without need of any postoperative adjunctive procedure. RESULTS: Sixty-three patients were included. Stent was removed at urethroplasty in 61 patients. Reconstruction technique was excision and primary anastomosis in 14 (22.2%), dorsal onlay buccal mucosa graft (BMG) in 9 (14.3%), ventral onlay BMG in 6 (9.5%), dorsolateral onlay BMG in 9 (14.3%), ventral onlay plus dorsal inlay BMG in 3 (4.8%), augmented anastomosis in 5 (7.9%), pedicled flap urethroplasty in 6 (9.5%), 2-stage procedure in 4 (6.4%), and perineal urethrostomy in 7(11.1%). Success rate was 81% at a mean 59.7 ± 63.4 months. Dilatation or internal urethrotomy was performed in 10 (15.9%) and redo-urethroplasty in 5 (7.9%). Total International Prostate Symptom Score, quality of life, urine maximum flow, and postvoid residual significantly improved (P <.0001). Complications occurred in 8 (12.7%), all Clavien-Dindo ≤2. Disease-free survival rate after reconstruction was 88.1%, 79.5%, and 76.7% at 1, 3, and 5 years, respectively. Explant of individual strands followed by onlay BMG is the most common approach and was significantly advantageous over the other techniques (P = .018). CONCLUSION: Urethroplasty in patients with Urolume urethral stents is a viable option of reconstruction with a high success rate and very acceptable complication rate. Numerous techniques are viable; however, urethral preservation, tine-by-tine stent extraction, and use of BMG augmentation produced significantly better outcomes.

RESUMO

INTRODUCTION: The objective of this study was to report outcome measures with third-generation pre-attached scrotal port adjustable transobturator male system (ATOMS) for male stress urinary incontinence (SUI) after radical prostatectomy. METHODS: A prospective open study was conducted on consecutive patients. Evaluation included cough test, urethroscopy, filling and voiding cystometry, 24-h pad count and pad test, patient-reported outcomes (ICIQ-SF, IIQ-7, PGI, GRA, and VAS), complications according to the Clavien-Dindo system, operative results, number of adjustments, and filling of the system. RESULTS: Thirty-four patients with median pad test 510 (170-1225) ml were operated on. Preoperative SUI was mild (5.9%), moderate (17.6%), and severe (76.5%). At median 18.5 (12-26) months follow-up distribution of SUI was none (85.3%), mild (8.8%), and moderate (5.9%). Median intraoperative filling was 14 (8-17) ml, number of adjustments 1 (0-5), and total filling 17.5 (11-33.5) ml. At 3 months, median ICIQ-SF (p = 0.0001) and IIQ-7 (p < 0.0001) decreased. At 12 months, 24-h pad count and pad test decreased (both p < 0.0001), residual volume slightly increased (p = 0.018), PGI-I was 1 (1-3), GRA 6 (3-6), and 97% were satisfied with treatment. Continence (p = 0.016) and satisfaction (p = 0.09) were worse in irradiated patients. Median operative time was 67 (35-120) min, hospital stay 1 (1-3) days, and VAS for pain on postoperative day 1 was 0 (0-2). Complications presented in 14.7% (8.8% grade I and 5.9% grade III). CONCLUSION: Treatment of severe male SUI after radical prostatectomy with pre-attached scrotal port ATOMS is safe and very effective in the short term. A positive cough test before implant and intraoperative overfilling of the system may optimize patient selection and results.
