Systematic Reviews and Meta-analyses of the Procedure-specific Risks of Thrombosis and Bleeding in General Abdominal, Colorectal, Upper Gastrointestinal, and Hepatopancreatobiliary Surgery.

OBJECTIVE: To provide procedure-specific estimates of symptomatic venous thromboembolism (VTE) and major bleeding after abdominal surgery. BACKGROUND: The use of pharmacological thromboprophylaxis represents a trade-off that depends on VTE and bleeding risks that vary between procedures; their magnitude remains uncertain. METHODS: We identified observational studies reporting procedure-specific risks of symptomatic VTE or major bleeding after abdominal surgery, adjusted the reported estimates for thromboprophylaxis and length of follow-up, and estimated cumulative incidence at 4 weeks postsurgery, stratified by VTE risk groups, and rated evidence certainty. RESULTS: After eligibility screening, 285 studies (8,048,635 patients) reporting on 40 general abdominal, 36 colorectal, 15 upper gastrointestinal, and 24 hepatopancreatobiliary surgery procedures proved eligible. Evidence certainty proved generally moderate or low for VTE and low or very low for bleeding requiring reintervention. The risk of VTE varied substantially among procedures: in general abdominal surgery from a median of <0.1% in laparoscopic cholecystectomy to a median of 3.7% in open small bowel resection, in colorectal from 0.3% in minimally invasive sigmoid colectomy to 10.0% in emergency open total proctocolectomy, and in upper gastrointestinal/hepatopancreatobiliary from 0.2% in laparoscopic sleeve gastrectomy to 6.8% in open distal pancreatectomy for cancer. CONCLUSIONS: VTE thromboprophylaxis provides net benefit through VTE reduction with a small increase in bleeding in some procedures (eg, open colectomy and open pancreaticoduodenectomy), whereas the opposite is true in others (eg, laparoscopic cholecystectomy and elective groin hernia repairs). In many procedures, thromboembolism and bleeding risks are similar, and decisions depend on individual risk prediction and values and preferences regarding VTE and bleeding.

Practice Variation in the Management of Adult Hydroceles: A Multinational Survey.

Background: Although hydrocele is one of the most common urologic pathologies, it is seldom studied, and the major urologic associations have no guidelines for the management of adult hydroceles. Objective: To characterize international practice variation in the treatment of adult hydroceles. Design setting and participants: An international survey was conducted addressing the management of hydroceles among urologists in Belgium, Denmark, Finland, Iceland, Japan, and the Netherlands from September to December 2020. We invited a random sample of 170 urologists from each country (except Iceland). Outcome measurements and statistical analysis: Urologists' treatment options, factors relevant for decision-making, expected patient satisfaction, and outcomes after aspiration versus surgery were assessed. Results and limitations: Of the 864 urologists contacted, 437 (51%) participated. Of the respondents, 202 (53%) performed both hydrocelectomies and aspiration, 147 (39%) performed hydrocelectomies only, and 30 (8%) performed aspiration only. In Belgium (83%), the Netherlands (75%), and Denmark (55%), urologists primarily performed hydrocelectomies only, whereas in Finland (84%), Japan (61%), and Iceland (91%), urologists performed both hydrocelectomies and aspiration. Urologists favored hydrocelectomy for large hydroceles (78.8% vs 37.5% for small), younger patients (66.0% for patients <50 yr vs 41.2% for ≥70 yr), patients with few or no comorbidities (62.3% vs 23.1% with multiple comorbidities), and patients without antithrombotic agents (53.5% vs 36.5% with antithrombotic agents). Most urologists considered patient satisfaction to be highest after hydrocelectomy (53.8% vs 9.9% after aspiration) despite believing that hydrocelectomy is more likely to cause complications (hematoma 77.8% vs 8.8% after aspiration). Estimates varied between countries. Conclusions: We found a large variation in the treatment of adult hydroceles within and between countries. Optimization of hydrocele management globally will require future studies. Patient summary: Our international survey shows that treatment of adult hydrocele varies considerably within and between countries.

Response to Medical Assistance in Dying, Palliative Care, Safety, and Structural Vulnerability.

This report, signed by >170 scholars, clinicians, and researchers in palliative care and related fields, refutes the claims made by the previously published Medical Assistance in Dying, Palliative Care, Safety, and Structural Vulnerability. That report attempted to argue that structural vulnerability was not a concern in the provision of assisted dying (AD) by a selective review of evidence in medical literature and population studies. It claimed that palliative care has its own safety concerns, and that "misuse" of palliative care led to reports of wrongful death. We and our signatories do not feel that the conclusions reached are supported by the evidence provided in the contested report. The latter concluded that the logical policy response would be to address the root causes of structural vulnerability rather than restrict access to AD. Our report, endorsed by an international community of palliative care professionals, believes that public policy should aim to reduce structural vulnerability and, at the same time, respond to evidence-based cautions about AD given the potential harm.

The Burden of Uncontrolled Cardiovascular Risk Factors in Men With Prostate Cancer: A RADICAL-PC Analysis.

Background: Cardiovascular disease (CVD) incidence is higher in men with prostate cancer (PC) than without. Objectives: We describe the rate and correlates of poor cardiovascular risk factor control among men with PC. Methods: We prospectively characterized 2,811 consecutive men (mean age 68 ± 8 years) with PC from 24 sites in Canada, Israel, Brazil, and Australia. We defined poor overall risk factor control as ≥3 of the following: suboptimal low-density lipoprotein cholesterol (>2 mmol/L if Framingham Risk Score [FRS] ≥15 and ≥3.5 mmol/L if FRS <15), current smoker, physical inactivity (<600 MET min/wk), suboptimal blood pressure (BP) (≥140/90 mm Hg if no other risk factors, systolic BP ≥120 mm Hg if known CVD or FRS ≥15, and ≥130/80 mm Hg if diabetic), and waist:hip ratio >0.9. Results: Among participants (9% with metastatic PC and 23% with pre-existing CVD), 99% had ≥1 uncontrolled cardiovascular risk factor, and 51% had poor overall risk factor control. Not taking a statin (odds ratio [OR]: 2.55; 95% CI: 2.00-3.26), physical frailty (OR: 2.37; 95% CI: 1.51-3.71), need for BP drugs (OR: 2.36; 95% CI: 1.84-3.03), and age (OR per 10-year increase: 1.34; 95% CI: 1.14-1.59) were associated with poor overall risk factor control after adjustment for education, PC characteristics, androgen deprivation therapy, depression, and Eastern Cooperative Oncology Group functional status. Conclusions: Poor control of modifiable cardiovascular risk factors is common in men with PC, highlighting the large gap in care and the need for improved interventions to optimize cardiovascular risk management in this population.

Timing of symptomatic venous thromboembolism after surgery: meta-analysis.

BACKGROUND: The timing at which venous thromboembolism (VTE) occurs after major surgery has major implications for the optimal duration of thromboprophylaxis. The aim of this study was to perform a systematic review and meta-analysis of the timing of postoperative VTE up to 4 weeks after surgery. METHODS: A systematic search of MEDLINE, Scopus, and CINAHL databases was performed between 1 January 2009 and 1 April 2022. Prospective studies that recruited patients who underwent a surgical procedure and reported at least 20 symptomatic, postoperative VTE events by time were included. Two reviewers independently selected studies according to the eligibility criteria, extracted data, and evaluated risk of bias. Data were analysed with a Poisson regression model, and the GRADE approach was used to rate the certainty of evidence. RESULTS: Some 6258 studies were evaluated, of which 22 (11 general, 5 urological, 4 mixed, and 2 orthopaedic postoperative surgical populations; total 1 864 875 patients and 24 927 VTE events) were eligible. Pooled evidence of moderate certainty showed that 47.1 per cent of the VTE events occurred during the first, 26.9 per cent during the second, 15.8 per cent during the third, and 10.1 per cent during the fourth week after surgery. The timing of VTE was consistent between individual studies. CONCLUSION: Although nearly half of symptomatic VTE events in first 4 weeks occur during the first postoperative week, a substantial number of events occur several weeks after surgery. These data will inform clinicians and guideline developers about the duration of postoperative thromboprophylaxis.

Hundreds of millions of surgical procedures are performed annually worldwide. Blood clots in legs and lungs represent serious, and sometimes fatal, complications of surgery. To prevent these complications, clinicians often give blood thinners to patients. To optimize the starting time and duration of use of blood thinners, it is crucial to know when blood clots occur after surgery. This study summarized the timing of blood clots after surgery based on a systematic review and meta-analysis of 22 prospective studies including thousands of patients with blood clots from various surgical fields. Of blood clots occurring within 4 weeks after surgery, 47 per cent occurred by the first, 74 per cent by the second, and 90 per cent by the third week after surgery. These research results are useful for patients, clinicians, and guideline developers to guide the starting time and duration of use of blood thinners after surgery.

Emergency holmium laser enucleation of the prostate (HoLEP): a novel approach in the management of refractory hematuria for patients with benign prostatic hyperplasia (BPH): a single-institution experience.

INTRODUCTION: Refractory hematuria secondary to prostatic disease typically resolves with conservative management; however, this condition may require hospitalization with extensive measures to control life-threatening bleeding. The aim of this study was to report our experience using holmium laser enucleation of the prostate (HoLEP) as an emergency treatment in this clinical setting. METHODS: We conducted a retrospective review of all patients that presented to the emergency department with refractory hematuria of prostatic origin from October 2017 to September 2021, for whom hospitalization and conservative management failed to control bleeding. All emergency HoLEP procedures were performed by a single surgeon. Preoperative and intraoperative parameters, as well as perioperative outcomes, were collected and analyzed. Postoperative outcomes included duration of foley catheterization, length of postoperative hospital stay, and hospital readmissions. RESULTS: A total of 40 emergency HoLEP procedures were performed. Our cohort had a median prostate volume of 110.5 cc and a median resected weight of 81 g. Twenty-seven patients (67.5%) were on anticoagulant or antiplatelet medications on admission. The urethral catheter was removed within 1 day in 95% of patients with a successful trial of void (TOV). Moreover, 92.5% of patients were discharged home within 24 h of their procedure. Two patients (5%) experienced clot retention within one-week post-discharge with a 2.5% overall readmission rate. All postoperative parameters, including International Prostate Symptom Score (IPSS), quality of life (QoL), maximum flow rate (Qmax), and post-void residual volume (PVR), showed significant improvement at 1 year follow up. CONCLUSION: Our experience demonstrates that emergency HoLEP is an effective treatment option for patients with refractory hematuria of prostatic origin. Further studies are warranted to consolidate our results.

Systematic Review of the Incidence of and Risk Factors for Urothelial Cancers and Renal Cell Carcinoma Among Patients with Haematuria.

CONTEXT: The current impact of haematuria investigations on health care organisations is significant. There is currently no consensus on how to investigate patients with haematuria. OBJECTIVE: To evaluate the incidence of bladder cancer, upper tract urothelial carcinoma (UTUC), and renal cell carcinoma (RCC) among patients undergoing investigation for haematuria and identify any risk factors for bladder cancer, UTUC, and RCC (BUR). EVIDENCE ACQUISITION: Medline, Embase, and Cochrane controlled trials databases and ClinicalTrials.gov were searched for all relevant publications from January 1, 2000 to June 2021 according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. Prospective, retrospective, and cross-sectional studies with a minimum population of 50 patients with haematuria were considered for the review. EVIDENCE SYNTHESIS: A total of 44 studies were included. The total number of participants was 229701. The pooled incidence rate for urothelial bladder cancer was 17% (95% confidence interval [CI] 14-20%) for visible haematuria (VH) and 3.3% (95% CI 2.45-4.3%) for nonvisible haematuria (NVH). The pooled incidence rate for RCC was 2% (95% CI 1-2%) for VH and 0.58% (95% CI 0.42-0.77%) for NVH. The pooled incidence rate for UTUC was 0.75% (95% CI 0.4-1.2%) for VH and 0.17% (95% CI 0.081-0.299%) for NVH. On sensitivity analysis, the proportions of males (risk ratio [RR] 1.14, 95% CI 1.10-1.17 for VH; 1.54, 95% CI 1.34-1.78 for NVH; p < 0.00001; moderate certainty evidence) and individuals with a smoking history (RR 1.41, 95% CI 1.24-1.61 for VH; 1.53, 95% CI 1.36-1.72 for NVH; p < 0.00001; moderate certainty evidence) appeared to be higher in BUR than in non-BUR groups. CONCLUSIONS: Male gender and smoking history are risk factors for BUR cancer in haematuria, with bladder cancer being the commonest cancer. The incidence of RCC and UTUC in NVH is low. The review serves as a reference standard for future policy-making on investigation of haematuria by global organisations. PATIENT SUMMARY: Our review shows that male gender and smoking history are risk factors for cancers of the bladder, kidney, and ureter. The review also provides information on the proportion of patients who have cancer when they have blood in their urine (haematuria) and will allow policy-makers to decide on the most appropriate method for investigating haematuria in patients.

Benefits and harms of direct oral anticoagulation and low molecular weight heparin for thromboprophylaxis in patients undergoing non-cardiac surgery: systematic review and network meta-analysis of randomised trials.

OBJECTIVE: To systematically compare the effect of direct oral anticoagulants and low molecular weight heparin for thromboprophylaxis on the benefits and harms to patients undergoing non-cardiac surgery. DESIGN: Systematic review and network meta-analysis of randomised controlled trials. DATA SOURCES: Medline, Embase, and the Cochrane Central Register of Controlled Trials (CENTRAL), up to August 2021. REVIEW METHODS: Randomised controlled trials in adults undergoing non-cardiac surgery were selected, comparing low molecular weight heparin (prophylactic (low) or higher dose) with direct oral anticoagulants or with no active treatment. Main outcomes were symptomatic venous thromboembolism, symptomatic pulmonary embolism, and major bleeding. Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were used for network meta-analyses. Abstracts and full texts were screened independently in duplicate. Data were abstracted on study participants, interventions, and outcomes, and risk of bias was assessed independently in duplicate. Frequentist network meta-analysis with multivariate random effects models provided odds ratios with 95% confidence intervals, and GRADE (grading of recommendations, assessment, development, and evaluation) assessments indicated the certainty of the evidence. RESULTS: 68 randomised controlled trials were included (51 orthopaedic, 10 general, four gynaecological, two thoracic, and one urological surgery), involving 45 445 patients. Low dose (odds ratio 0.33, 95% confidence interval 0.16 to 0.67) and high dose (0.19, 0.07 to 0.54) low molecular weight heparin, and direct oral anticoagulants (0.17, 0.07 to 0.41) reduced symptomatic venous thromboembolism compared with no active treatment, with absolute risk differences of 1-100 per 1000 patients, depending on baseline risks (certainty of evidence, moderate to high). None of the active agents reduced symptomatic pulmonary embolism (certainty of evidence, low to moderate). Direct oral anticoagulants and low molecular weight heparin were associated with a 2-3-fold increase in the odds of major bleeding compared with no active treatment (certainty of evidence, moderate to high), with absolute risk differences as high as 50 per 1000 in patients at high risk. Compared with low dose low molecular weight heparin, high dose low molecular weight heparin did not reduce symptomatic venous thromboembolism (0.57, 0.26 to 1.27) but increased major bleeding (1.87, 1.06 to 3.31); direct oral anticoagulants reduced symptomatic venous thromboembolism (0.53, 0.32 to 0.89) and did not increase major bleeding (1.23, 0.89 to 1.69). CONCLUSIONS: Direct oral anticoagulants and low molecular weight heparin reduced venous thromboembolism compared with no active treatment but probably increased major bleeding to a similar extent. Direct oral anticoagulants probably prevent symptomatic venous thromboembolism to a greater extent than prophylactic low molecular weight heparin.

Low Serum Testosterone in Men with Newly Diagnosed Androgen-Deprivation Therapy-Naïve Prostate Cancer and Its Relationship to Cardiovascular Risk Factors: A RADICAL-PC Substudy.

PURPOSE: Cardiovascular disease is a common cause of death in prostate cancer patients. Low testosterone is associated with increased cardiovascular risk in the general male population. We investigated the relationship between serum testosterone, cardiovascular disease and risk factors in androgen-deprivation therapy-naïve prostate cancer patients. MATERIALS AND METHODS: We performed a cross-sectional analysis of a subgroup of 1,326 androgen-deprivation therapy-naïve men from RADICAL-PC (Role of Androgen-Deprivation Therapy In CArdiovascular Disease-A Longitudinal Prostate Cancer study) in whom serum testosterone was measured at baseline. RADICAL-PC is a prospective multicenter cohort study of men (2,565) enrolled within 1 year of prostate cancer diagnosis, or within 6 months of commencing androgen-deprivation therapy for the first time. Cardiovascular risk factors, cancer characteristics and total serum testosterone were collected at baseline. Low testosterone was defined as total serum testosterone <11 nmol/L (<320 ng/dL). A Framingham cardiovascular risk score ≥15 was considered high risk for future cardiovascular events. We performed logistic regression to calculate odds ratios for the association between testosterone and cardiovascular risk. RESULTS: Among 1,326 participants (median age 67 years, range 45-93), 553 (42%) had low testosterone. Low testosterone was associated with existing cardiovascular disease, diabetes, elevated hemoglobin A1c, obesity, hypertriglyceridemia, low high-density lipoprotein cholesterol, hypertension and Framingham score >15. Among patients with low testosterone, the odds ratio for high cardiovascular risk was 1.33 (1.02-1.73) after adjusting for ethnicity, education, alcohol use, cancer characteristics, physical activity and body mass index. CONCLUSIONS: Among androgen-deprivation therapy-naïve prostate cancer patients, low testosterone is common and associated with increased cardiovascular risk factors.

Evaluation of Benefits and Harms of Surgical Treatments for Post-radical Prostatectomy Urinary Incontinence: A Systematic Review and Meta-analysis.

CONTEXT: No meta-analysis has comprehensively addressed both benefits and harms, or the certainty of evidence of the implantable continence devices used in men to treat postprostatectomy urinary incontinence (PPI). OBJECTIVE: To evaluate the benefits and harms of surgical treatments for patients suffering from PPI and assess the certainty of evidence. The primary benefit was cure (one or fewer pad per day), and the primary harm was reoperations defined by surgical procedures following implantation. EVIDENCE ACQUISITION: We perform a search of Medline, PubMed, Embase, Cochrane Library, and gray literature. We included observational studies addressing PPI surgical interventions if they involved cohorts of ≥50 participants. The Grading of Recommendations, Assessment, Development and Evaluations (GRADE) approach provided the framework for certainty of evidence assessment informed by value and preference judgments provided by patients, and an advocacy group member (Canadian Cancer Society). EVIDENCE SYNTHESIS: Of 85 observational studies involving 13 100 patients, three addressed bulking agents, 35 male synthetic slings, ten adjustable continence therapies (ACTs), and 37 artificial urinary sphincters (AUSs). Cure was 26.1% (95% confidence interval [CI]: 10.6-51.4, I2 = 92.8%, very-low-quality evidence) for bulking agents, 58.6% (95% CI: 51.3-65.5, I2 = 89.1%, low-quality evidence) for slings, 63.2% (95% CI: 57.6-68.5, I2 = 22.5%, very-low-quality evidence) for ACT, and 74.0% (95% CI:61.2-83.7, I2 = 92.1%, very-low-quality evidence) for AUS. Estimated rates of reoperation were 5.8% (95% CI: 1.9-11.6, I2 = 94.1%, moderate-quality evidence) for slings, 23.8% (95% CI: 5.9-61.0, I2 = 95.5%, low-quality evidence) for ACT, and 22.2% (95% CI: 15.2-31.3, I2 = 92.3%, high-quality evidence) for AUS. CONCLUSIONS: Available evidence regarding the benefits of surgical interventions for PPI remains mainly uncertain while suggesting important harms. These results should guide consent procedures for PPI surgery in the context of shared decision-making, with disclosure of the uncertainty of evidence. PATIENT SUMMARY: Despite being used worldwide, available evidence regarding the benefits of surgeries to treat postprostatectomy urinary incontinence remains mainly uncertain while suggesting important harms. This highlights the need for a more rigorous evaluation process for commercially available surgical devices.

Shared decision-making in urology and female pelvic floor medicine and reconstructive surgery.

Shared decision-making (SDM) is a hallmark of patient-centred care that uses informed consent to help guide patients with making complex health-care decisions. In SDM, patients and providers work together to determine the best course of action based on both the current available evidence and the patient's values and preferences. SDM not only provides a framework for the legal and ethical obligations providers need to fulfil for informed consent, but also leads to improved knowledge of treatment options and satisfaction of decision-making for patients. Tools such as decision aids have been developed to support SDM for complex decisions. Several decision aids are available for use in the field of urology and female pelvic medicine and reconstructive surgery, but these decision aids are also associated with barriers to SDM implementation including patient, provider and systematic challenges. However, solutions to such barriers to SDM include continued development of SDM tools to improve patient engagement, expand training of providers in SDM communication models and a process to encourage implementation of SDM.

Evidence-based Urology: Trustworthy Guidelines.

Clinical guidelines for guiding clinical decision-making must be trustworthy, especially when there is controversy or a shifting paradigm. In urology, the management of small renal masses is one area in which there is currently a paradigm shift towards active surveillance. A number of international guidelines address this paradigm shift to some extent, with varying degrees of rigor. To be trustworthy, guidelines should be developed by panels that include content experts - the traditional panel members - as well as methodologists with expertise in evidence interpretation, front-line clinicians who take care of the patients who constitute the target audience, and patient partners. At a minimum, panels should integrate four key concepts: (1) guidelines provide a systematic summary of evidence used to support answerable questions, including assessment of the quality of the evidence; (2) there is a clear and transparent link between the evidence and recommendations; (3) recommendations incorporate patient values and preferences; and (4) conflicts of interest are managed optimally. In this article we address several issues in four international guidelines, with an emphasis on guideline methods and implications for guidance statements. The strengths and limitations of available recommendations are reviewed and summarized with suggestions for improving the next iterations of guidelines on the management of small renal masses. PATIENT SUMMARY: Good clinical decision-making relies on trustworthy guidelines. We assessed four international guidelines on the management of small kidney tumors that illustrate some of the key issues in developing a trustworthy guideline. Patient values and preferences are under-represented in most clinical guidelines.

ARTS: A Large, International Trial of Thromboprophylaxis in Intra-abdominal, Gynecologic, and Urologic Surgery.

ARTS will be the first trial to compare anticoagulation with a direct oral anticoagulant (apixaban) versus no anticoagulation among patients undergoing intra-abdominal, gynecologic, or urologic surgery at sufficiently similar risk of deep vein thrombosis or pulmonary embolism and major bleeding.

An International Survey on the Use of Thromboprophylaxis in Urological Surgery.

BACKGROUND: The use of perioperative thromboprophylaxis in urological surgery is common but not standardized. OBJECTIVE: To characterize international practice variation in thromboprophylaxis use in urological surgery. DESIGN, SETTING, AND PARTICIPANTS: We conducted a scenario-based survey addressing the use of mechanical and pharmacological thromboprophylaxis in urological cancer procedures (radical cystectomy [RC], radical prostatectomy [RP], and radical nephrectomy [RN]) among practicing urologists in Canada, Finland, and Japan. The survey presented patient profiles reflecting a spectrum of risk for venous thromboembolism; the respondents described their clinical practice. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The proportion of respondents who routinely used (1) mechanical, (2) pharmacological, and (3) extended pharmacological prophylaxis was stratified by procedure. A logistic regression identified characteristics associated with thromboprophylaxis use. RESULTS AND LIMITATIONS: Of 1051 urologists contacted, 570 (54%) participated in the survey. Japanese urologists were less likely to prescribe pharmacological prophylaxis than Canadian or Finnish urologists (p < 0.001 for all procedures). Canadian and Finnish urologists exhibited large variation for extended pharmacological prophylaxis for RP and RN. Finnish urologists were most likely to prescribe extended prophylaxis versus Canadian and Japanese urologists (RC 98%, 84%, and 26%; Open RP 25%, 8%, and 3%; robotic RP 11%, 9%, and 0%; and RN 43%, 7%, and 1%, respectively; p < 0.001 for each procedure). Less variation was found regarding the prescription of mechanical prophylaxis, which was most commonly used until ambulation or discharge. The length of hospital stay was longer in Japan and may bias estimates of extended prophylaxis in Japan. CONCLUSIONS: We found large variation in clinical practice regarding pharmacological thromboprophylaxis within and between countries. Knowledge translation of evidence-based guidelines may reduce problematic international variation in practice. PATIENT SUMMARY: Use of medications to decrease blood clots after urological cancer surgery differs within and between countries. Closer adherence to urology guidelines addressing the prevention of blood clots may decrease this variation and improve patient outcomes.

Psychological morbidity associated with prostate cancer: Rates and predictors of depression in the RADICAL PC study.

INTRODUCTION: Across all cancer sites and stages, prostate cancer has one of the greatest median five-year survival rates, highlighting the important focus on survivorship issues following diagnosis and treatment. In the current study, we sought to evaluate the prevalence and predictors of depression in a large, multicenter, contemporary, prospectively collected sample of men with prostate cancer. METHODS: Data from the current study were drawn from the baseline visit of men enrolled in the RADICAL PC study. Men with a new diagnosis of prostate cancer or patients initiating androgen deprivation therapy for prostate cancer for the first time were recruited. Depressive symptoms were evaluated using the nine-item version of the Patient Health Questionnaire (PHQ-9). To evaluate factors associated with depression, a multivariable logistic regression model was constructed, including biological, psychological, and social predictor variables. RESULTS: Data from 2445 patients were analyzed. Of these, 201 (8.2%) endorsed clinically significant depression. Younger age (odds ratio [OR] 1.38, 95% confidence interval [CI] 1.16-1.60 per 10-year decrease), being a current smoker (OR 2.77, 95% CI 1.66-4.58), former alcohol use (OR 2.63, 95% CI 1.33-5.20), poorer performance status (OR 5.01, 95% CI 3.49-7.20), having a pre-existing clinical diagnosis of depression or anxiety (OR 3.64, 95% CI 2.42-5.48), and having high-risk prostate cancer (OR 1.49, 95% CI 1.05-2.12) all conferred independent risk for depression. CONCLUSIONS: Clinically significant depression is common in men with prostate cancer. Depression risk is associated with a host of biopsychosocial variables. Clinicians should be vigilant to screen for depression in those patients with poor social determinants of health, concomitant disability, and advanced disease.

Canadian Urological Association guideline on male urethral stricture.

Urethral stricture is fundamentally a fibrosis of the urethral epithelial and associated corpus spongiosum, which in turn, causes obstruction of the urethral lumen. Patients with urethral stricture most commonly present with lower urinary tract symptoms, urinary retention or urinary tract infection but may also experience a broad spectrum of other signs and symptoms, including genitourinary pain, hematuria, abscess, ejaculatory dysfunction, or renal failure. When urethral stricture is initially suspected based on clinical assessment, cystoscopy is suggested as the modality that most accurately establishes the diagnosis. This recommendation is based on several factors, including the accuracy of cystoscopy, as well as its wide availability, lesser overall cost, and comfort of urologists with this technique. When recurrent urethral stricture is suspected, we suggest performing retrograde urethrography to further stage the length and location of the stricture or referring the patient to a physician with expertise in reconstructive urology. Ultimately, the treatment decision depends on several factors, including the type and acuity of patient symptoms, the presence of complications, prior interventions, and the overall impact of the urethral stricture on the patient's quality of life. Endoscopic treatment, either as dilation or internal urethrotomy, is suggested rather than urethroplasty for the initial treatment of urethral stricture. This recommendation applies to men with undifferentiated urethral stricture and does not apply to trauma-related urethral injuries, penile urethral strictures (hypospadias, lichen sclerosus), or suspected urethral malignancy. In the setting of recurrent urethral stricture, urethroplasty is suggested rather than repeat endoscopic management but this may vary depending on patient preference and impact of the symptoms on the patient.The purpose of this guideline is to provide a practical summary outlining the diagnosis and treatment of urethral stricture in the Canadian setting.
