RESUMO
INTRODUCTION: Individuals with spina bifida (SB) may experience negative health outcomes because of an informal transition from pediatric to adult care that results in using the emergency room (ER ) for non-acute health problems. METHODS: We conducted a retrospective, population-based cohort study of all people with SB in Ontario, Canada turning 18 years old between 2002 and 2011. These patients were followed for five years before and after age 18. Primary outcome was the annual rate of ER visits. Secondary outcomes included rates of hospitalization, surgery, primary care, and specialist outpatient care. We estimated the association between age and primary and secondary outcomes using negative binomial growth curve models, adjusting for patient-level baseline covariates. RESULTS: Among the 1215 individuals with SB, there was no trend of ER visits seen with increasing age (relative risk [RR ] 0.99, 95% confidence interval [CI] 0.98-1.02); however, there was a significant increase in the rate of ER visits associated with turning 18 years (RR 1.14, 95% CI 1.03-1.27). Turning 18 years old was also associated with a decreased rate of hospital admissions (RR 0.79, 95% CI 0.66-0.95) and no change in surgeries (RR 0.80, 95% CI 0.64-1.02). Visits to primary care physicians remained stable over the same period (RR 0.96, 95% CI 0.90-1.01), while visits to SB-focused specialists decreased after age 18 (RR 0.81, 95% CI 0.75-0.87). CONCLUSIONS: In patients with SB, the rate of ER visits increased significantly at 18 years old, while hospital admissions and specialist physician visits decreased at the same time. Models of transitional care can aim to reduce non-urgent ER visits and facilitate regular specialist care.
RESUMO
OBJECTIVES: To compare the risk of bladder cancer and bladder cancer mortality among patients with chronic bladder catheterisation (indwelling or intermittent) to patients from the general population. DESIGN: Retrospective cohort study. SETTING: Population-based study in Ontario, Canada between 2003 and 2018. PARTICIPANTS: Adult patients 18-90 years of age with chronic bladder catheterisation were hard matched to patients from the general population without a history of bladder catheterisation. INTERVENTIONS: The presence of a chronic catheter was defined as a minimum of two physician encounters for bladder catheterisation, suprapubic tube insertion or home care for catheter care separated by at least 28 days. Urinary tract infection (UTI) rates were collected. MAIN OUTCOME MEASURES: Bladder cancer and bladder cancer-specific mortality after a 1-year lag period were compared between groups. RESULTS: We identified 36 903 patients with chronic catheterisation matched to 110 709 patients without a history of catheterisation. Patients were followed for a median of 8.8 years (IQR: 5.2-11.9 years). The median age was 62 years (IQR: 50-71) and 52% were female. More patients in the catheter group developed bladder cancer (393 (1.1%) vs 304 (0.3%),p<0.001). There were 106 (0.3%) bladder cancer deaths in the catheter group and 59 (0.1%) in the comparison group (p<0.001). Chronic catheterisation (adjusted subdistribution HR (sdHR)=4.80, 95% CI: 4.26 to 5.42,p<0.001) and the number of UTIs (adjusted sdHR=1.04 per UTI, 95% CI: 1.04 to 1.05,p<0.001) were independent predictors of bladder cancer. The relative rate of bladder cancer-specific death was more than eightfold higher among patients with chronic catheterisation (adjusted sdHR=8.68, 95% CI: 6.97 to 10.81,p<0.001). Subgroup analysis among patients with neurogenic bladder and bladder calculi similarly revealed an increased risk of bladder cancer diagnosis and mortality. Bladder cancer risk was highest among patients in the two longest catheter duration quintiles (2.9-5.9 and 5.9-15.5 years). CONCLUSIONS: This is the first study to quantify the increase in bladder cancer incidence and mortality in a large, diverse cohort of patients with chronic indwelling or intermittent bladder catheterisation. The risk was highest among patients with a chronic catheter beyond 2.9 years.

PURPOSE: We sought to determine if stress urinary incontinence surgery (mesh or nonmesh) is associated with the development of pelvic malignancies later in life. MATERIALS AND METHODS: We performed a retrospective cohort study between January 1, 2002 and October 31, 2015 of all women in Ontario, Canada without a history of pelvic malignancy who underwent an index stress incontinence surgery. The primary outcome was a composite of any pelvic malignancy (including urological and gynecological cancers) following stress incontinence surgery. Secondarily, we considered each cancer individually. A survival analysis using a Cox proportional-hazards model with a 3-level categorical exposure (mesh surgery, nonmesh surgery, and control) was performed. Patients were followed until death, emigration or the study end (October 31, 2017). RESULTS: Of the women 74,968 underwent stress urinary incontinence surgery during the study period. There were 5,505,576 women in the control group. Over a median followup of 8.5 years (IQR, 5.5-11.9), 587 pelvic malignancies occurred in the surgery group. Women who underwent stress incontinence surgery had a reduced risk of pelvic malignancy independent of surgery type, compared to controls (Wald type 3 p <0.001; mesh HR, 0.68 [95% CI, 0.62-0.76]; p <0.0001; nonmesh HR, 0.37 [95% CI, 0.29-0.46]; p <0.0001). The individual pelvic cancers similarly demonstrated a reduced risk of malignancy following stress incontinence surgery. CONCLUSIONS: At a median followup of 8.5 years, women had no increased risk of pelvic malignancy following either mesh or nonmesh stress urinary incontinence surgery in a large population-based cohort.

INTRODUCTION: With the cessation of non-urgent clinical office visits due to the coronavirus, there has been a rapid shift to telephone and other virtual visits in outpatient practice. We conducted a survey to evaluate patients' perspective of telephone visits during the COVID-19 pandemic. METHODS: Patients receiving a scheduled telephone call as a virtual visit from urologists at our clinic were asked to participate in a three-minute, self-administered, online questionnaire. After verbal permission was obtained, the survey was emailed to each participant. The outcomes evaluated were telephone visit satisfaction and preference for type of appointment. Non-parametric tests were used to analyze the results. The study was approved by the Sunnybrook Research Ethics Board. RESULTS: A total of 102 participants were included; 96% of participants assessed the telephone visit as a positive experience in every survey question, while 45% expressed no preference. In those who expressed a preference, this was evenly divided between in-office visits and phone visits (p=0.0614). Participants who lived more than 75 km from the hospital were less likely to prefer an in-office visit compared to those residing locally (U=433, p=0.006; odds ratio 0.29, 95% confidence interval 0.106-0.779, p=0.0142). CONCLUSIONS: In this survey, most participants assessed the telephone visit positively. Almost half had no preference and a similar proportion expressed a preference for in-office and telephone visits. Patients who resided farther from the hospital were more likely to prefer the telephone visit. This is the first study that we know of to assess patients' preferences regarding remote encounters in urology.
RESUMO
INTRODUCTION: Our aim was to explore the satisfaction, personal and professional challenges, and practice barriers among female urologists in Canada. METHODS: A literature review was completed to design our survey. Trends with respect to career and personal satisfaction were identified, including academic advancement, mentorship, professional challenges, workplace discrimination, family satisfaction, and remuneration, among others. These key themes were formatted into 44 questions, translated into French, and distributed electronically as a survey to 80 female urology staff across Canada. RESULTS: Sixty (75.0%) women completed the survey. Many had been in practice <5 years (44.1%) and 72.9% completed a fellowship. Overall, 96.6% of women were very or somewhat satisfied with their career. Seeing more time-consuming patients and financial constraints within the healthcare system were the greatest source of dissatisfaction. Two-thirds of respondents reported that they received significant mentorship and 40% found it difficult to find a mentor during their training. Overall, 65.0% experienced gender discrimination, most commonly from a colleague or a patient. Women who practiced in the community were more likely to report experiencing discrimination compared to women practicing in an academic setting (78.1% vs. 51.9%; p=0.034). Mean time for maternity leave was 17.1 (±8.3) weeks, and 30.2% reported a pregnancy-related complication triggered by their work. Overall, 66.1% would choose urology again. CONCLUSIONS: It is important to advocate for the wellness of female urologists. To accomplish this, we need to address the challenges revealed in the survey, including supporting women on maternity leave, improving mentorship, and prioritizing female urology leadership initiatives. We have established a formal circle of support within the urology community in Canada to achieve these goals.
RESUMO
INTRODUCTION: Benign prostatic obstruction (BPO) due to histological benign prostatic hyperplasia is highly prevalent among older men. Despite widespread use of medical therapy, surgical treatment remains a mainstay in the management of BPO. We sought to characterize trends in the surgical management of BPO in Ontario, Canada. METHODS: We performed an interrupted time-series analysis using segmented regression among men aged 18 years and older undergoing surgical treatment for BPO between January 1, 1994 and December 31, 2014 in Ontario, Canada. The passage of time was considered the primary exposure. The primary outcome was the proportion of all BPO surgeries performed using each of the following modalities: transurethral resection of the prostate (TURP), endoscopic laser prostatectomy, open/laparoscopic prostatectomy, and others. RESULTS: We identified 136 459 men who underwent BPO surgery between 1994 and 2014. The annual age-adjusted rate of BPO surgery declined significantly over time (24 to 10 per 10 000 population in 1994 and 2014, respectively). From 1994-2001, there were no significant changes in the distribution of BPO surgical modalities, with TURP the most common throughout (97.2% and 97% in 1994 and 2001, respectively). From 2002-2014, there was a significant decline in the use of TURP (92.1% to 76.9%; p=0.027) with a corresponding increase in the use of endoscopic laser prostatectomy (3.5% to 21.9%; p=0.0008). CONCLUSIONS: This study demonstrates a shift in the management of BPO, with increasing use of endoscopic laser prostatectomy, beginning in 2002. However, TURP remains the most common treatment modality.
RESUMO
PURPOSE: Previous studies have shown an association between urinary incontinence and increased mortality independently of demographics and health status. However, they do not account for the effect of frailty as a state of vulnerability. We evaluated whether there is an association between urinary incontinence and mortality and, if so, whether adjustment for a frailty index would affect the association. MATERIALS AND METHODS: We performed a cross-sectional study in a nationally representative sample of 2,282 community dwelling individuals 50 years old or older who were surveyed between 2003 and 2006. The study primary outcome was overall survival as reported on December 31, 2011. We used design adjusted Cox proportional hazards regression models to estimate the hazard of mortality associated with urinary incontinence. We adjusted the models for demographics and a validated 45-item frailty index incorporating an accumulation of deficits in the domains of health and independence. RESULTS: Of the individuals 23% reported having urinary incontinence at least a few times per week. Stress urinary incontinence and urge urinary incontinence were associated with a 13.3% (95% CI 7.2-19.7) and 18.4% (95% CI 8.3-29.4) increase in the frailty index, respectively. Without controlling for frailty individuals with urinary incontinence were at higher risk for death (HR 1.39, 95% CI 1.13-1.72). When adjusted for the frailty index, the association between urinary incontinence and mortality was no longer significant (HR 1.10, 95% CI 0.89-1.36). CONCLUSIONS: The association between urinary incontinence and mortality can be understood based on increased frailty in incontinent individuals. Urinary incontinence itself is not independently associated with mortality. In clinical practice these findings underscore the importance of screening for frailty in addition to urinary incontinence.

INTRODUCTION: Interstitial cystitis/bladder pain syndrome (IC/BPS) is a devastating urological chronic pelvic pain condition with an unknown etiology. Evidence-based psychological strategies are becoming more successful for symptom management as we learn more about the targets for intervention. Previous research has established an indirect relationship between depression and pain through catastrophizing, but there have yet to be studies examining the emerging role of emotion regulation in this relationship. METHODS: Women with IC/BPS were recruited from tertiary care clinics in Canada and the U.S. between 2013 and 2018. Patients completed questionnaires, including demographics and scores for pain, depression, catastrophizing, and difficulties in emotion regulation at baseline, six months, and one year. Serial mediation was used to test models of pain, catastrophizing, and depression. RESULTS: A total of 135 women with IC/BPS completed all three time points. The only significant indirect path was from baseline depression to catastrophizing at six months to pain at one year (b=0.10; confidence interval [CI] 0.0049-0.2520). A followup analysis demonstrated that helplessness was the key factor of catastrophizing driving this relationship (b=0.17; CI 0.0282-0.3826). CONCLUSIONS: Reducing feelings of helplessness and increasing patient feelings of control are important ways to limit the effect of low mood on patient pain experience. De-catastrophizing interventions should be part of the referral strategy for IC/BPS symptom management.
RESUMO
OBJECTIVES: To examine the complication rates after benign prostatic enlargement (BPE) surgery and the effects of age, comorbidity and preoperative medical therapy. DESIGN: A retrospective, population-based cohort study using linked administrative data. SETTING: Ontario, Canada. PARTICIPANTS: 52 162 men≥66 years undergoing first BPE surgery between 1 January 2003 to 31 December 2014. INTERVENTION: Medical therapy preoperatively and surgery for BPE. PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcome was overall 30-day postoperative complication rates. Secondary outcomes included BPE-specific event rates (bleeding, infection, obstruction, trauma) and non-BPE specific event rates (cardiovascular, pulmonary, thromboembolic and renal). Multivariable analysis examined the association between preoperative medical therapy and postoperative complication rates. RESULTS: The 30-day overall complication rate after BPE surgery was 2828 events/10 000 procedures and increased annually over the study period. Receipt of preoperative α-blocker monotherapy (relative rate (RR) 1.05; 95% CI 1.00 to 1.09; p=0.033) and antithrombotic medications (RR 1.27; 95% CI 1.22 to 1.31; p<0.0001) was associated with increased complication rates. Among the ≥80-year-old group, the rate of complications increased by 39% from 2003 to 2014 (RR 1.39; 95% CI 1.21 to 1.61; p<0.0001). The mean duration of medical and conservative management increased by a mean of 2.1 years between 2007 and 2014 (p<0.0001 for trend). CONCLUSIONS: Thirty-day complication rates after BPE surgery have increased annually between 2003 and 2014. Preoperative medical therapy with alpha blockers or antithrombotics was independently associated with higher rates of complications. Over this time, the duration of conservative therapy also increased.

PURPOSE: The purpose of the study was to assess safety and efficacy of autologous muscle derived cells for urinary sphincter repair (AMDC-USR) in female subjects with predominant stress urinary incontinence. METHODS: A randomized, double-blind, multicenter trial examined intra-sphincteric injection of 150 × 106 AMDC-USR versus placebo in female subjects with stress or stress predominant, mixed urinary incontinence. AMDC-USR products were generated from vastus lateralis needle biopsies. Subjects were randomized 2:1 to receive AMDC-USR or placebo and 1:1 to receive 1 or 2 treatments (6 months after the first). Primary outcome was composite of ≥ 50% reduction in stress incontinence episode frequency (IEF), 24-h or in-office pad weight tests at 12 months. Other outcome data included validated subject-recorded questionnaires. Subjects randomized to placebo could elect to receive open-label AMDC-USR treatment after 12 months. Subject follow-up was up to 2 years. RESULTS: AMDC-USR was safe and well-tolerated with no product-related serious adverse events or discontinuations due to adverse events. Interim analysis revealed an unexpectedly high placebo response rate (90%) using the composite primary outcome which prevented assessment of treatment effect as designed and thus enrollment was halted at 61% of planned subjects. Post hoc analyses suggested that more stringent endpoints lowered placebo response rates and revealed a possible treatment effect. CONCLUSIONS: Although the primary efficacy finding was inconclusive, these results inform future trial design of AMDC-USR to identify clinically meaningful efficacy endpoints based on IEF reduction, understanding of placebo response rate, and refinement of subject selection criteria to more appropriately align with AMDC-USR's proposed mechanism of action.

BACKGROUND: Interstitial Cystitis/Bladder Pain Syndrome (IC/BPS) is a urologic chronic pelvic pain syndrome with suboptimal treatment outcomes. Catastrophizing is an empirically supported risk factor for greater IC/BPS pain. AIMS: In this study, a moderated multiple mediation model is tested in which several additional psychosocial risk factors (depression, illness and wellness-focused behavioral coping strategies) are proposed as mediators or moderators in the existing relationship between catastrophizing and IC/BPS pain. DESIGN: The present questionnaire study employed a cross-sectional design. SETTINGS AND PARTICIPANTS: Female patients with an IC/BPS diagnosis (n = 341) were recruited at tertiary care sites. METHODS: Participants completed questionnaires assessing pain, catastrophizing, behavioral coping strategies, and depressive symptoms. Aggregate factor scores were calculated following exploratory factor analyses. RESULTS: It was found that patients with a greater tendency to catastrophize were more likely to engage in illness-focused coping strategies, which contributed to the reporting of greater sensory and affective pain. Furthermore, this mediating effect of illness-focused coping on affective pain was more likely to occur in those patients reporting greater depressive symptoms. CONCLUSIONS: Illness-focused behavioral coping is an important mechanism between maladaptive pain cognition and aspects of patient pain, with patients reporting greater depressive symptoms at increased risk for elevated pain. Patient management techniques, including screening for catastrophizing, coping, and depression, are recommended to enrich IC/BPS management.

INTRODUCTION: We hypothesize that optimal management of interstitial cystitis/bladder pain syndrome requires more personalized data than obtained with symptom questionnaires and standard urological assessment. We used a qualitative approach to develop a best evidence series of questions to explore the total clinical picture in the patient with interstitial cystitis/bladder pain syndrome. METHODS: The methodology of this project included preliminary focus groups, individual patient interviews, content development and validity analyses to develop a series of questions of value to patients with interstitial cystitis/bladder pain syndrome. A new convenience sample of patients with this syndrome completed the series of questions exploring not only pain and urination symptoms, but also other biopsychosocial parameters noted to be of relevance to these patients. RESULTS: Content of final series of questions addressed pain, urination symptoms, flares and the 10 most important domains impacted by interstitial cystitis/bladder pain syndrome. Further questions addressed thoughts or feelings, attitudes and suicidal ideation. A series of questions addressed how patients cope with and manage their condition. A total of 32 patients with interstitial cystitis/bladder pain syndrome completed the finalized series of questions. Bladder pain and urination symptoms were primary concerns of patients but other domains related to associated nonurological conditions (poor sleep/persistent fatigue, irritable bowel syndrome-like symptoms, low back and general muscle pain, interference/impact [eg sleep, diet, travel, activities, sexual functioning], positive and negative beliefs/attitudes, and coping mechanisms) make up the total clinical picture for each patient. CONCLUSIONS: The biopsychosocial information provided by our patients will better inform the health care professional on how to develop personalized treatment strategies and also individualized patient directed outcomes independent of bladder pain and urination symptoms.
RESUMO
OBJECTIVES: To examine a self-regulation and coping model for interstitial cystitis/bladder pain syndrome (IC/BPS) that may help us understand the pain experience of patients with chronic IC/BPS. PATIENTS AND METHODS: The model tested illness perceptions, illness-focused coping, emotional regulation, mental health and disability in a stepwise method using factor analysis and structural equation modelling. Step 1, explored the underlying constructs. Step 2, confirmed the measurement models to determine the structure/composition of the main constructs. Step 3, evaluated the model fit and specified pathways in the proposed IC/BPS self-regulation model. In all, 217 female patients with urologist diagnosed IC/BPS were recruited and diagnosed across tertiary care centres in North America. The data were collected through self-report questionnaires. RESULTS: An IC/BPS self-regulation model was supported. Physical disability was worsened by patient's negative perception of their illness, attempts to cope using illness-focused coping and poorer emotional regulation. Mental health was supported by perceptions that individuals could do something about their illness, using wellness-focused behavioural strategies and adaptive emotion regulation. CONCLUSIONS: The results clarify the complex and unique process of self-regulation in women with IC/BPS, implicating cognitive and coping targets, and highlighting emotional regulation. This knowledge should help clinicians understand and manage these patients' distress and disability.

INTRODUCTION: We sought to understand the contemporary pharmacologic management of overactive bladder (OAB) in a single-payer system. We examined temporal trends in the use of anticholinergic medications and assessed whether the likelihood of patients changing their anticholinergic therapy was predicted by their current therapy. METHODS: We conducted a retrospective, population-based analysis of prescription records from the PharmaNet database in BC, Canada. We identified patients treated with one or more anticholinergic prescriptions between 2001 and 2009. We characterized temporal trends in the use of anticholinergic medications. We used generalized estimating equations with a logit wing to assess the relationship between the type of anticholinergic medication and the change in prescription. RESULTS: The 114 325 included patients filled 1 140 296 anti-cholinergic prescriptions. The number of prescriptions each year increased over the study, both in aggregate and for each individual medication. While oxybutynin was the most commonly prescribed medication (68% of all prescriptions), the proportion of newer anticholinergics (solifenacin, darifenacin, and trospium) prescribed increased over time (p<0.0001). Patients taking tolterodine (odds ratio [OR] 1.03; p=0.01) and darifenacin (OR 1.12; p=0.0006) were significantly more likely to change their prescription than those taking oxybutynin. There was no association seen for patients taking solifenacin (p=0.6) and trospium (p=0.9). CONCLUSIONS: There are an increasing number of anticholinergic prescriptions being filled annually. Patients taking newer anticholinergics are at least as likely to change therapy as those taking oxybutynin. The reimbursement environment in BC likely affects these results. Restrictions in the available data limit assessment of other relevant predictors.
RESUMO
OBJECTIVE: To determine the occurrence of lower genitourinary tract (LGUT) injury during hysterectomy for benign disease and identify risk factors for LGUT injury, with a specific focus on the effect of hysterectomy modality. METHODS: We performed a retrospective cohort study of patients undergoing hysterectomy for benign disease from 2010 t o 2014 using the American College of Surgeons National Surgical Quality Improvement Program, a multi-institutional prospective registry that captures perioperative surgical outcomes. We identified the occurrence of concomitant cystoscopy and therapeutic urologic interventions including endoscopic ureteric stenting, ureteric repair, bladder repair, cystectomy, and urinary diversion as a proxy for LGUT injuries. Adjusted odds ratios and 95% confidence intervals were calculated using multivariate logistic regression. RESULTS: We identified 101,021 patients treated with hysterectomy for benign disease: 18,610 (18.4%), 27,427 (27.2%), and 54,984 (54.4%) underwent vaginal, open, and laparoscopic hysterectomy, respectively. Cystoscopy was performed in 16,493 cases (16.3%). There were 2427 patients (2.4%) who underwent concomitant urologic intervention. Patients undergoing laparoscopic hysterectomy had increased occurrence of urologic intervention, excluding cystoscopy (adjusted odds ratio 1.47, 95% confidence interval 1.29-1.69), compared to vaginal hysterectomy; no differences were found between open and vaginal hysterectomy or laparoscopic and open hysterectomy. Larger uteri, a postoperative diagnosis of endometriosis, increasing comorbidity, and African American race were associated with an increased odd of urologic intervention whereas concomitant cystoscopy was associated with a decreased chance. CONCLUSION: The incidence of lower genitourinary tract intervention in benign hysterectomy is significant and may be higher than previously reported. Predisposing patient factors and operative technique are key risk factors.

INTRODUCTION: We sought to evaluate psychosocial factors as predictors of suicidal ideation (SI) in a tertiary care outpatient sample of women suffering from interstitial cystitis/bladder pain syndrome (IC/BPS). METHODS: The patients are women managed at tertiary care centres (n=190). Controls were recruited from the community (n=117). Both groups completed questionnaires on demographics, pain (McGill Pain Questionnaire), IC/BPS symptoms, and psychological variables. Univariate and multivariate hierarchical regression modelling was conducted to examine the strength of associations and unique effects of psychosocial variables on patient SI. RESULTS: Compared to 6% in healthy controls, 23% of patients endorsed SI in the past two weeks. Correlations between SI, depression, and catastrophizing across controls and cases show that for controls, SI is associated with greater pain (0.31; p<0.01) and depression only (0.59; p<0.01). For tertiary care centre cases, SI is associated with pain (0.24; p<0.01), depression (0.64; p<0.01), and catastrophizing (0.35; p<0.01). Regression analyses indicated that psychosocial variables accounted for a significant amount of variance over and above IC/BPS symptoms. Catastrophizing (i.e., helplessness) about pain and depression were significant univariate predictors of SI, but only depression predicted SI in multivariable analyses. CONCLUSIONS: Limitations of this study include its cross-sectional design and primarily correlation-based statistics. The present study is the first to implicate multiple psychosocial risk factors over and above IC/BPS-specific symptoms and patient pain experience in SI in women with IC/BPS. Depression in particular is uniquely important in predicting suicidality. These results support a multidisciplinary, proactive approach to IC/BPS involving not only treatment of disease symptoms, but also early detection/treatment of associated psychosocial problems.
RESUMO
INTRODUCTION: We assess the practice patterns of artificial urinary sphincter (AUS) and urethral sling insertion after radical prostatectomy (RP) from a large population-based cohort. METHODS: We examined 25 346 men in Ontario, Canada who underwent RP between 1993 and 2006. Using hospital and cancer registry data, we identified patients who subsequently underwent an incontinence procedure. We characterized the practice patterns of post-prostatectomy incontinence procedures across Ontario during the study interval. RESULTS: A total of 703 (2.8%) men underwent subsequent insertion of an AUS and 282 (1.1%) underwent a urethral sling procedure (985 total incontinence procedures, 3.9%) over the study period. During the study period, 121 hospitals performed RP. Among them, 32 (26%) hospitals performed both RP and AUS/sling procedures, and 89 (74%) performed RP only. Four hospitals performed AUS/sling procedures but not RP. Of the 36 institutions that performed AUS/sling procedures, the median annual case volume was 0.29 (interquartile range: 0.083-0.75). Of all incontinence procedures, 56% were performed at 3 academic institutions. When examining observed rates of AUS/sling procedures compared with expected rates from the overall cohort, 15 of 32 hospitals (47%) performed significantly fewer incontinence procedures than expected given their RP case volume (p range: <0.0001-0.0390) and 5 (16%) performed significantly more (p range: <0.0001-0.038). CONCLUSIONS: A small number of academic institutions provide most of the surgical care for men with incontinence following RP in Ontario. Many centres that perform RP refer out to other centres to surgically manage their patients' incontinence.
RESUMO
PURPOSE: We assess the 12-month safety and potential efficacy of autologous muscle derived cells for urinary sphincter repair (Cook MyoSite Incorporated, Pittsburgh, Pennsylvania) in women with stress urinary incontinence. MATERIALS AND METHODS: Pooled data from 2 phase I/II studies with identical patient selection criteria and outcome measures were analyzed. Enrolled patients had stress urinary incontinence refractory to prior treatment and no symptom improvement during the last 6 months. Patients received intrasphincter injection of 10 (16), 50 (16), 100 (24) or 200×10(6) (24) autologous muscle derived cells for urinary sphincter repair, derived from biopsies of each patient's quadriceps femoris. The primary outcome measure was safety, determined by incidence and severity of adverse events. Potential efficacy was measured by changes in 3-day voiding diaries, 24-hour pad tests, and UDI-6 and IIQ-7 scores. RESULTS: A total of 80 patients underwent injection of autologous muscle derived cells for urinary sphincter repair, and 72 completed diaries and pad tests at 12-month followup. No adverse events attributed to autologous muscle derived cells for urinary sphincter repair were reported. Higher dose groups tended to have greater percentages of patients with at least a 50% reduction in stress leaks and pad weight at 12-month followup. All dose groups had statistically significant improvement in UDI-6 and IIQ-7 scores at 12-month followup compared to baseline. CONCLUSIONS: Autologous muscle derived cells for urinary sphincter repair at doses of 10, 50, 100 and 200×10(6) cells appears safe. Efficacy data suggest a potential dose response with a greater percentage of patients responsive to higher doses.
