RESUMEN

INTRODUCTION: This study aims to determine the accuracy of radiological imaging compared with surgical pathology in patients with periurethral (PU) and anterior vaginal wall (AVW) lesions. METHODS: This study is a retrospective analysis of 126 women who underwent surgical treatment for PU and AVW masses between 2011 and 2020. Clinicopathological data were extracted along with radiological findings from medical records. The primary outcome was the diagnostic accuracy of preoperative imaging compared to the gold standard, pathological diagnosis. The secondary outcome was the rate of imaging correcting the clinical diagnosis. RESULTS: A total of 126 women with a median age of 42 underwent surgical treatment for PU and AVW masses. The most diagnoses were periurethral cysts (PUC) (52%) and urethral diverticulum (UD) (39%). Clinical diagnosis was accurate in 102 cases (81%) for the group of pathological diagnoses. Magnetic resonance imaging (MRI) and transvaginal ultrasound (TV US) were performed in 82 (65%) and 22 (17%) cases. The accuracy of MRI and TV US for the diagnosis of PU and AVW lesions was 76% and 82%, respectively. MRI and TV US corrected the clinical diagnosis in five (6%) and two (9%) cases, respectively. Voiding cystourethrography (VCUG) and double balloon urethrography (DBU), each performed in six (5%) cases, were accurate in four (67%) and three (50%) cases. No statistical difference was found for any imaging modality compared to clinical diagnosis. CONCLUSION: Clinical diagnosis based on pelvic and cystoscopy examinations was sufficient for diagnosing PU and AVW masses and was not significantly different from imaging diagnosis. Imaging may be helpful with preoperative surgical planning in selected cases.

RESUMEN

PURPOSE: Refractory bladder neck contracture (BNC) following transurethral prostatectomy is rare and difficult to manage. Success rate of endoscopic treatment decline considerably after repeated treatments. Bladder neck reconstruction are often the last resort to treat refractory BNC failing endoscopic treatments. In general, experience is limited with this type of bladder neck reconstruction, particularly in adult patients. This study aims to determine the success rate, functional and patient-reported outcomes (PRO) of open Y-V plasty in treatment of refractory BNC after transurethral prostatectomy. The study also aims to determine the rate, and potential predictors of persistent storage symptoms after Y-V plasty. MATERIALS AND METHODS: Between January 2016 and February 2021, 18 consecutive patients with refractory BNC who underwent open Y-V plasty were included in this study. All patients presented with voiding dysfunction after two or more failed attempts of endoscopic treatments followed by a 3-month period of outpatient serial dilation program. Clinicopathological data were extracted from medical records including baseline demographics, aetiology of BNC, previous endoscopic treatment, operative time, length of stay, complications, uroflow findings, International Prostate Symptom Score (IPSS) and OAB-V8. Primary outcome was the success of open YV plasty, defined as no need for further instrumentation such as indwelling catheterization, urethral dilatation, urethrotomy, or open surgery. Simple linear regression analysis was performed to determine predictor factors for postoperative OAB-V8. Variables that showed p < 0.25 were included in the multiple linear regression analysis. RESULTS: Most common aetiology of BNC was transurethral resection of prostate gland (n = 18, 100%). Mean age at surgery age (SD) was 65.5 (7.3) years. Mean follow-up was 14.8 (7) months. Success rate was 100%. Postoperative Qmax improved significantly [pre-OP 6.7 (8.1) ml/s vs. post-OP was 14.8 (7.3) ml/s, p < 0.001]. Mean postvoid residual decreased significantly [pre-OP 223.3 (254.3) ml vs. post-OP 45.1 (71.0) ml, p < 0.01)]. Persistent storage symptoms were reported in 61% of patients. BMI and baseline IPSS score are significant predictors for the postoperative OAB V8 change (adjusted b (95% confidence interval) = 1.037 (0.2-1.9), 0.64 (0.28-0.99), respectively, R2 = 0.59). CONCLUSION: Y-V plasty reconstruction for refractory BNC represents a feasible and successful option with high success rate and favorable outcomes. While functional and patient-reported outcomes had significantly improved post-operatively, persistent storage symptoms after this procedure still exist. BMI and baseline IPSS score are significant predictors for persistent storage symptoms after bladder neck reconstruction.

RESUMEN

BACKGROUND: Injecting onabotulinumtoxinA (BoTN-A) into the bladder has been established as an effective treatment of overactive bladder (OAB) and well-tolerated by patients. However, there evidence suggests the efficacy and safety of this treatment may decrease with age due to increased comorbidities and frailty. This study's objective was to establish empirical evidence regarding age-related differences in outcomes related to BoTN-A for the treatment of idiopathic OAB. METHODS: MEDLINE, EMBASE, and the Cochrane Central Registry for Controlled Trials were systematically searched. Results were restricted to randomized control trials of BoTN-A bladder injections for the treatment of idiopathic OAB. The resulting articles' abstracts were screened independently by two reviewers. Those passing the screen were reviewed in full. Articles were excluded if participants were <18 years old, diagnosed with neurogenic overactivity, or treated with both oral medications and BoTN-A; if the frequency and severity of OAB symptoms were not specified; or, if symptoms were not stratified by age. RESULTS: The initial search resulted in 1572 articles; 166 were reviewed in full. None met all inclusion/exclusion criteria. However, 21 studies met all criteria except age stratification. Authors were contacted to obtain raw data to perform an independent age-based analysis, but sufficient data was not received. CONCLUSION: While the initial systematic review did not generate the expected results, it did reveal that age-related outcomes of BoTN-A for the treatment of OAB are significantly under-studied. Given that the prevalence of OAB increases with age, this is an important knowledge gap. Our article explains the rationale for further study in this area.

RESUMEN

INTRODUCTION: This study aimed to describe the effects of bladder function following radiotherapy for localized prostate cancer by performing a systematic review on studies reporting on urodynamic findings after radiotherapy. METHODS: This systematic review was conducted in accordance with PRISMA guidelines. The review protocol was registered at PROSPERO (CRD42021229037). A systematic search was conducted using PubMed, Cochrane Library, Scopus, and OVID Embase. Studies were included if they involved men who underwent urodynamic studies following radiotherapy for localized prostate cancer. A total of 798 articles were screened and five articles included. A qualitative analysis was performed. RESULTS: Bladder compliance appears to be impaired following radiotherapy, especially with longer followup. Impaired bladder compliance was reported in 18.8-62.5% of patients following radiotherapy. Bladder capacity was found to be statistically significantly lower following radiotherapy compared to pre-radiotherapy, and when compared with patients who did not undergo pelvic radiotherapy. Bladder outlet obstruction (BOO) persists post-radiotherapy in most patients at three and 18 months post-radiotherapy. De novo detrusor overactivity (DO) of 13.3% has been reported at 18 months post-radiotherapy. This review is limited by the absence of level I/II studies. CONCLUSIONS: Radiotherapy for localized prostate cancer results in decreased bladder compliance and capacity demonstrated on urodynamic studies. Resolution of BOO appears less likely in comparison to series on radical prostatectomy. De novo DO may develop following radiotherapy, especially with longer followup. With only low level of evidence studies available at present, further high-quality, prospective studies are important to elucidate the impact of radiotherapy on bladder and urethral function.

RESUMEN

INTRODUCTION: The relationship between prostate cancer (PCa) and overactive bladder (OAB) is poorly understood. PCa and OAB are frequently diagnosed in elderly populations, so it could be expected that both conditions would be observed in older patients. Whether PCa and OAB occur independently with age, or the presence of PCa leads to the onset of OAB/lower urinary tract symptoms (LUTS) has not been explored. This review aimed to investigate whether men newly diagnosed with PCa are more likely to have OAB compared to the general population, and if the various treatment modalities for PCa are likely to impact the incidence or exacerbation of OAB. METHODS: The University of Calgary's databases for Medline and PubMed were searched for relevant publications. No restrictions were placed on the study design reported. Any publications reporting OAB and a PCa diagnosis and/or observation relating to PCa diagnosis and rates of OAB/LUTS in an adult population were included for full review. RESULTS: Of the studies examining the relationship between PCa and LUTS, results varied, but frequently indicated an inverse association between PCa and LUTS in which patients newly diagnosed with PCa were more unlikely to have LUTS compared to the general population. Following treatment, brachytherapy resulted in a higher prevalence of OAB symptoms compared to surgical treatment and external beam radiation therapy. CONCLUSIONS: Diverse evidence was found regarding the relationship between the prevalence of pre-treatment OAB and PCa diagnosis. However, limited evidence, as well as uncertainty regarding pre-treatment symptoms and their impact on post-treatment outcomes, restricts potential conclusions.

RESUMEN

AIMS: This study aims to describe the effects of radical prostatectomy (RP) on bladder function by performing a systematic review of urodynamics study findings before and after RP. METHODS: This systematic review was conducted in accordance with the PRISMA guideline and registered on PROSPERO (CRD42020206844). A systematic search was conducted using PubMed, Cochrane, and Embase. Studies were included if they involved men who underwent RP and had urodynamics study performed preoperatively, postoperatively, or both. Studies that included only subgroups of patients based on symptoms were excluded. Three hundred and four articles were screened, with 20 articles included. A qualitative analysis was performed. RESULTS: The rate of baseline bladder outlet obstruction (BOO) pre-RP was 19%-67%. All six studies with comparative data pre- and postoperatively demonstrated a decrease in the rate of patients with equivocal or clear obstruction. The baseline rates of detrusor overactivity (DO) varied widely from 11% to 61.2%. Six of eight studies with 6 months or more follow-up showed an improvement in the rates of DO ranging from 3.0% to 12.5%. The rate of de novo DO ranged from 0% to 54.5%. Four studies reported an increased rate of impaired bladder contractility and two of three studies showed a worsening rate of impaired bladder compliance following RP. This review is limited by the absence of level I/II studies. CONCLUSIONS: Urodynamics study shows that BOO is improved following RP in most patients. RP resolves DO in some patients and cause de novo DO in others. The net effect is a reduced overall rate of DO in most studies. Bladder compliance and contractility may be impaired after RP.

RESUMEN

BACKGROUND: Research on prostate cancer survivorship patients has largely been on oncological outcome, incontinence and erectile dysfunction, with less data on the relationship between prostate cancer, bladder function and mental health. This study aims to elucidate the prevalence of lower urinary tract symptoms (LUTS), overactive bladder (OAB), sexual dysfunction, depression and anxiety in Canadian men with newly diagnosed localised prostate cancer. METHODS: This is a single-centre prospective cross-sectional study of men with newly diagnosed localized prostate cancer recruited from June 2017 to July 2018. The patient-reported outcomes (PRO) instruments used in this study included the international prostate symptoms score (IPSS), OAB-V8, EQ-5D™, and the Expanded Prostate Cancer Index Composite short form (EPIC-26). Clinico-pathological data were extracted from medical records. The prevalence of LUTS, OAB, sexual dysfunction, depression and anxiety were determined from the PROs. RESULTS: A total of 83 patients were included in this study. The median age was 63. Based on IPSS scores, 55.3% of men had mild LUTS, 36.8% had moderate LUTS and 7.9% had severe LUTS. Based on OAB-V8 scores, 55.8% of men had a score of 8 or higher, suggestive of OAB. Only 55.8% of men reported erections adequate for intercourse. 23.1% of men reported to have a moderate to big problem with depression, and 28.8% of men reported to have a degree of anxiety or depression. CONCLUSIONS: OAB is a significant problem in men with newly diagnosed localized prostate cancer, with a prevalence of 55.8% based on this study. Baseline sexual dysfunction, anxiety and depression are also prevalent in this population.

RESUMEN

INTRODUCTION: We aimed to evaluate the psychometric properties of the 26-item Expanded Prostate Cancer Index Composite (EPIC-26) for measuring the quality of life in patients treated for localized prostate cancer. The EPIC-26 is a patient-reported outcome instrument recommended for use with patients treated for localized prostate cancer. METHODS: This study is based on data collected prospectively between September 2014 and February 2017 in Alberta, Canada. Men were treated with either radical prostatectomy or radiation therapy and administered the EPIC-26. Responses to the EPIC-26 were the primary outcome. Construct validity was measured using confirmatory factor analysis. Reliability was measured using Chronbach's alpha and item-total correlation. Ceiling and floor effects were also investigated. RESULTS: EPIC-26 response data from 205 participants (prostatectomy =138; radiation=60; both=7) were used in this analysis. The EPIC-26 was administered an average of 33.8 weeks after treatment. The confirmatory factor analysis model did not meet the threshold for adequate fit. Several items had near-zero factor loadings and were non-significant. Four out of the EPIC-26's five domains met the acceptable reliability threshold based on Cronbach's alpha. Ceiling effects were observed in four out of five domains. CONCLUSIONS: The EPIC-26 demonstrated poor construct validity, adequate reliability, and large ceiling effects. Several issues were observed, suggesting that the instrument's five domains were not well-defined by their respective items. The original EPIC's conceptual framework should be reviewed and the shortened instrument revised to improve its performance for measuring post-treatment quality of life.

RESUMEN

Diabetic bladder dysfunction affects almost half of all diabetic patients, making it one of the most common complications of diabetes mellitus. The clinical presentation of diabetic bladder dysfunction can be varied and may be extremely bothersome to patients, negatively impacting their quality of life. Despite this, it remains understudied and under-represented in the medical literature. This review summarizes the current literature on pathophysiology, clinical presentation, urodynamic findings, evaluation, and management. Through this, we hope to provide guidance to clinicians involved with the management of this condition.

RESUMEN

A 60-year-old male presented to an emergency department (ED) with priapism following a sore throat illness. He did not have typical findings of sepsis. The patient then developed severe headache, mental status changes, and hypertension, then suffered a cardiopulmonary arrest. Autopsy showed group A streptococcal (GAS) sepsis, disseminated intravascular coagulation (DIC), and a septic thrombosis to the penile vein. This is the first known case of priapism being the presenting symptom of DIC.

RESUMEN

In recent years, midurethral slings (MUS) and transvaginal mesh procedures have experienced blazing growth and popularity. However, the US Food and Drug Administration (FDA) and Health Canada regulatory advisories threw water on that fire and created a confusing environment surrounding their continued usage. MUS usage has continued in Canada and transvaginal mesh kits for pelvic organ prolapse have become a rarity. Several large organizations (the Society of Urodynamics, Female Pelvic Medicine and Urogenital Reconstruction [SUFU], the American Urogynecologic Society [AUGS], and the Canadian Urological Association [CUA]) have developed "mesh statements" to clarify the issues surrounding mesh for patients and medical professionals; however, often the legal system sees things differently in either individual cases or class action lawsuits. In this update, some medicolegal basics are outlined and Canadian context on legal proceedings are highlighted. This summary does not constitute legal advice and physicians should contact experts in legal matters for help with consents, complaints, litigation, or questions.

RESUMEN

Stress incontinence (SUI) and pelvic organ prolapse (POP) are common conditions. There is high-level evidence that midurethral mesh slings for stress incontinence are effective and safe; however, the rare but serious potential risks of this surgery must be discussed with the patient. The use of transvaginal mesh for prolapse repair does not appear to be supported by the current evidence, and its use should be restricted to specialized pelvic floor surgeons and specific clinical situations.

RESUMEN

Mixed urinary incontinence is a common diagnosis among women with urinary leakage and is often present in women who are unable to characterize their incontinence. Research and optimized clinical treatment of these patients is limited by the challenges in objectively defining and stratifying this population. The evaluation of these patients should follow the same general principles as any assessment of any women with incontinence; however, it is essential to define whether urge or stress incontinence is the predominant symptom. Urodynamics (UDS) may be helpful in this regard and may help predict surgical outcomes. Behavioural therapy, weight loss, and pelvic floor muscle therapy are usually appropriate initial management strategies. In postmenopausal women, vaginal estrogen can be considered, and in women with equal parts stress and urge incontinence or urge-predominant mixed incontinence, a trial of anticholinergics or beta-3 agonists is appropriate. In women with stress-predominant or equal parts stress and urge incontinence, stress incontinence surgery can be considered, with the caveat that outcomes are generally worse among women with more severe levels of urgency, success rates may not be as durable, and a significant proportion of women may need additional medical therapy.

RESUMEN

Midurethral slings (MUS) are a proven effective treatment option for stress urinary incontinence (SUI) and have become the gold standard in most centres in North America. MUS implantation can be associated with risks that are common to all anti-incontinence surgeries, and others which are unique. This article reviews the intraoperative and the early and late postoperative risks associated with these procedures, with insights into their prevention, diagnosis, and management drawn from the literature and expert opinion. In most cases, careful patient counselling before and after surgery, along with meticulous surgical technique, can mitigate risk and patient concern. Even in the best of hands, however, complications will occur, so surgeons must have a high index of suspicion and a low threshold to investigate.

RESUMEN

While arteriovenous malformations (AVMs) are a common congenital or post-traumatic abnormality, male genital AVMs are rare and have been described in the scrotum or penis in pediatric patients.1,2 We describe a 34-year-old male presenting with recurrent spontaneous penile urethral bleeding found to have an AVM of the penile urethra. While angiography has traditionally been helpful, magnetic resonance imaging (MRI) can aid in the diagnosis and characterization of these lesions.3 Each case of male genital AVM provides a unique challenge to manage depending on the presenting complaint, as there are no guidelines to direct treatment.4.

RESUMEN

INTRODUCTION: Collecting patient-reported outcomes (PROs) can inform the treatment and management of overactive bladder (OAB). However, collecting these data at the point-of-care can be time-consuming and have a negative impact on a clinic's workflow. The purpose of this study was to pilot a digital system for collecting PROs at the point-of-care and qualitatively assess clinicians' perspectives in terms of the system's impact on the delivery of care for OAB. METHODS: Patients visiting a urology clinic for OAB completed several PRO instruments using a tablet while awaiting assessment. Clinicians reviewed their responses using a digital dashboard during clinical encounters. Qualitative interviews were conducted with the clinicians, to assess the collection system's impact in terms of: 1) logistics, 2) workflow; 3) patient communication; 4) influence on clinical decisions; 5) user experiences; and 6) the care model. RESULTS: Six interviews were conducted and thematic saturation was met, with several themes emerging. All participants were generally positive regarding the use of the digital collecting system. Participants felt that the dashboard improved workflow and enhanced communication with patients, but it was not thought to be any more influential on clinical decision-making than conventional collection methods. Several aspects of the digital PRO collection system were identified as needing improvement. CONCLUSIONS: The digital PRO collection system used at the point-of-care had a positive impact on the delivery of care for OAB. The results from this study could provide insight to other urologists who are interested in collecting PROs in their clinic.
