A multicenter prospective cohort study of endoscopic urethral realignment versus suprapubic cystostomy after complete pelvic fracture urethral injury.

BACKGROUND: Pelvic fracture urethral injury (PFUI) occurs in up to 10% of pelvic fractures. There is mixed evidence supporting early endoscopic urethral realignment (EUR) over suprapubic tube (SPT) placement and delayed urethroplasty. Some studies show decreased urethral obstruction with EUR, while others show few differences. We hypothesized that EUR would reduce the rate of urethral obstruction after PFUI. METHODS: Twenty-six US medical centers contributed patients following either an EUR or SPT protocol from 2015 to 2020. If retrograde cystoscopic catheter placement failed, patients were included and underwent either EUR or SPT placement based on their institution's assigned treatment arm. Endoscopic urethral realignment involved simultaneous antegrade/retrograde cystoscopy to place a catheter across the urethral injury. The primary endpoint was development of urethral obstruction. Fisher's exact test was used to analyze the relationship between PFUI management and development of urethral obstruction. RESULTS: There were 106 patients with PFUI; 69 (65%) had complete urethral disruption and failure of catheter placement with retrograde cystoscopy. Of the 69 patients, there were 37 (54%) and 32 (46%) in the EUR and SPT arms, respectively. Mean age was 37.0 years (SD, 16.3 years) years, and mean follow-up was 463 days (SD, 280 days) from injury. In the EUR arm, 36 patients (97%) developed urethral obstruction compared with 30 patients (94%) in the SPT arm ( p = 0.471). Urethroplasty was performed in 31 (87%) and 29 patients (91%) in the EUR and SPT arms, respectively ( p = 0.784). CONCLUSION: In this prospective multi-institutional study of PFUI, EUR was not associated with a lower rate of urethral obstruction or need for urethroplasty when compared with SPT placement. Given the potential risk of EUR worsening injuries, clinicians should consider SPT placement as initial treatment for PFUI when simple retrograde cystoscopy is not successful in placement of a urethral catheter. LEVEL OF EVIDENCE: Therapeutic/Care Management; Level III.

The Outcomes of Pelvic Fracture Urethral Injuries Stratified by Urethral Injury Severity: A Prospective Multi-institutional Genitourinary Trauma Study (MiGUTS).

OBJECTIVE: To determine patient outcomes across a range of pelvic fracture urethral injury (PFUI) severity. PFUI is a devastating consequence of a pelvic fracture. No study has stratified PFUI outcomes based on severity of the urethral distraction injury. METHODS: Adult male patients with blunt-trauma-related PFUI were followed prospectively for a minimum of six months at 27 US medical centers from 2015-2020. Patients underwent retrograde cystourethroscopy and retrograde urethrography to determine injury severity and were categorized into three groups: (1) major urethral distraction, (2) minor urethral distraction, and (3) partial urethral injury. Major distraction vs minor distraction was determined by the ability to pass a cystoscope retrograde into the bladder. Simple statistics summarized differences between groups. Multi-variable analyses determined odds ratios for obstruction and urethroplasty controlling for urethral injury type, age, and Injury Severity Score. RESULTS: There were 99 patients included, 72(72%) patients had major, 13(13%) had minor, and 14(14%) had partial urethral injuries. The rate of urethral obstruction differed in patients with major (95.8%), minor (84.6%), and partial injuries (50%) (P < 0.001). Urethroplasty was performed in 90% of major, 66.7% of minor, and 35.7% of partial injuries (P < 0.001). CONCLUSION: In PFUI, a spectrum of severity exists that influences outcomes. While major and minor distraction injuries are associated with a higher risk of developing urethral obstruction and need for urethroplasty, up to 50% of partial PFUI will result in obstruction, and as such need to be closely followed.

Ethnographic investigation of patient-provider communication among African American men newly diagnosed with prostate cancer: a study protocol.

INTRODUCTION: In the USA, African American men bear a disproportionate burden of prostate cancer (PCa) compared with all other groups, having a higher incidence and mortality, poorer quality of life and higher dissatisfaction with care. They are also less likely to receive guideline-concordant treatment (eg, undertreatment of aggressive disease). Inadequate patient-provider communication contributes to suboptimal care, which can be exacerbated by patients' limited health literacy, providers' lack of communication skills and time constraints in low-resource, safety net settings. This study is designed to examine the communication experiences of African American patients with PCa as they undertake treatment decision-making. METHODS AND ANALYSIS: Using an ethnographic approach, we will follow 25 African American men newly diagnosed with PCa at two public hospitals, from diagnosis through treatment decision. Data sources include: (1) audio-recorded clinic observations during urology, radiation oncology, medical oncology and primary care visits, (2) field notes from clinic observations, (3) patient surveys after clinic visits, (4) two in-depth patient interviews, (5) a provider survey, and (6) in-depth interviews with providers. We will explore patients' understanding of their diagnoses and treatment options, sources of support in decision-making, patient-provider communication and treatment decision-making processes. Audio-recorded observations and interviews will be transcribed verbatim. An iterative process of coding and team discussions will be used to thematically analyse patients' experiences and providers' perspectives, and to refine codes and identify key themes. Descriptive statistics will summarise survey data. ETHICS AND DISSEMINATION: To our knowledge, this is the first study to examine in-depth patient-provider communication among African American patients with PCa. For a population as marginalised as African American men, an ethnographic approach allows for explication of complex sociocultural and contextual influences on healthcare processes and outcomes. Study findings will inform the development of interventions and initiatives that promote patient-centred communication, shared decision-making and guideline-concordant care. This study was approved by the University of California San Francisco and the Alameda Health System Institutional Review Boards.

An American Association for the Surgery of Trauma (AAST) prospective multi-center research protocol: outcomes of urethral realignment versus suprapubic cystostomy after pelvic fracture urethral injury.

BACKGROUND: Pelvic fracture urethral injuries (PFUI) occur in up to 10% of pelvic fractures. It remains controversial whether initial primary urethral realignment (PR) after PFUI decreases the incidence of urethral obstruction and the need for subsequent urethral procedures. We present methodology for a prospective cohort study analyzing the outcomes of PR versus suprapubic cystostomy tube (SPT) after PFUI. METHODS: A prospective cohort trial was designed to compare outcomes between PR (group 1) and SPT placement (group 2). Centers are assigned to a group upon entry into the study. All patients will undergo retrograde attempted catheter placement; if this fails a cystoscopy exam is done to confirm a complete urethral disruption and attempt at gentle retrograde catheter placement. If catheter placement fails, group 1 will undergo urethral realignment and group 2 will undergo SPT. The primary outcome measure will be the rate of urethral obstruction preventing atraumatic passage of a flexible cystoscope. Secondary outcome measures include: subsequent urethral interventions, post-injury complications, urethroplasty complexity, erectile dysfunction (ED) and urinary incontinence rates. RESULTS: Prior studies demonstrate PR is associated with a 15% to 50% reduction in urethral obstruction. Ninety-six men (48 per treatment group) are required to detect a 15% treatment effect (80% power, 0.05 significance level, 20% loss to follow up/death rate). Busy trauma centers treat complete PFUI approximately 1-6 times per year, thus our goal is to recruit 25 trauma centers and enroll patients for 3 years with a goal of 100 or more total patients with complete urethral disruption. CONCLUSIONS: The proposed prospective multi-institutional cohort study should determine the utility of acute urethral realignment after PFUI.

Outcomes of men on active surveillance for low-risk prostate cancer at a safety-net hospital.

PURPOSE: To characterize demographic, disease, and cancer outcomes of men on active surveillance (AS) at a safety-net hospital and characterize those who were lost to follow-up (LTFU). METHODS: From January 2004 to November 2014, 104 men with low-risk prostate cancer (PCa) were followed with AS at Zuckerberg San Francisco General Hospital (ZSFG). Criteria for AS have evolved over time; however, patients with diagnostic prostate-specific antigen (PSA) 10ng/mL or less, clinical stage T1/2, biopsy Gleason score 3 + 3 or 3 + 4, 33% or fewer positive cores, and 50% or less tumor in any single core were potentially eligible for AS. Men were longitudinally followed with a PSA or digital rectal examination or both every 3 to 6 months, and repeat prostate biopsy every 1 to 2 years. Clinical staging and grading were based on a physical examination and at least a 12-core biopsy, respectively. LTFU was defined as failure to successfully contact patients with 3 phone calls or any urology visit recorded within 18 months from a prior visit or biopsy. A secondary chart review was performed using the electronic medical record at ZSFG as well as EPIC Systems CareEverywhere which allows access to select non-ZSFG institutions to confirm that patients were truly LTFU. RESULTS: Among the 104 men on AS at ZSFG, the median age at diagnosis of PCa was 61.5 years (range: 44-81). The median follow-up period was 29 months (range: 0-186 months) during which 18 (17.3%) men were LTFU and 48 (46%) remained on surveillance. Men underwent a median of 7 (1-21) serum PSA measurements and an average of 2 prostate biopsies (1-5). In total, 22 (20.6%) men had definitive treatment with the median time from diagnosis to active treatment being 26 (range: 2-87) months. Radiation therapy was more common than radical prostatectomy (12.5% vs. 7.7%). There was 1 PCa-related death and 3 noncancer deaths. Initial adherence to AS was poor; however, men committed to AS initially were ultimately more compliant over time. CONCLUSION: AS for low-risk PCa is challenging among a vulnerable population receiving care in a safety-net hospital, as rates of LTFU were high. Our findings suggest the need for AS support programs to improve adherence and follow-up among vulnerable and underserved populations.

Validation of a Visual Prostate Symptom Score in Men With Lower Urinary Tract Symptoms in a Health Safety Net Hospital.

OBJECTIVE: To evaluate the correlation between the International Prostate Symptom Score (IPSS) and the Visual Prostate Symptom Score (VPSS), a visual assessment of urinary stream, frequency, nocturia, and quality of life using pictograms, in a health safety net population. METHODS: Men presenting to San Francisco General Hospital with lower urinary tract symptoms completed the IPSS and the VPSS without and then with assistance. Statistical analysis was performed using the chi-square test, the Wilcoxon signed rank test, and the Spearman rank correlation. RESULTS: One hundred twenty-one patients were enrolled between December 2013 and May 2014 with a mean age of 54 years. There were statistically significant correlations between total VPSS and total IPSS (ρ = 0.71; P <.001) and for frequency (ρ = 0.47; P <.001), nocturia (ρ = 0.69; P <.001), force of stream (ρ = 0.65; P <.001), and quality of life (ρ = 0.69; P <.001). In addition, there were statistically significant correlations between total VPSS and both VPSS quality of life (ρ = 0.69; P <.001) and Qmax (ρ = -0.473; P = .006). The mean absolute disagreement for participants who took the IPSS independently vs with assistance was greater than for those who took the VPSS independently vs assistance for all symptoms: frequency (0.64 vs 0.3, respectively; P <.001), weak stream (0.82 vs 0.14, respectively; P <.001), nocturia (0.38 vs 0.23, respectively; P = .023), and quality of life (0.63 vs 0.32, respectively; P = .005). CONCLUSION: Many men altered their IPSS responses when they received assistance. There was significantly less alteration in responses using the VPSS, suggesting that the VPSS is useful in determining lower urinary tract symptoms, particularly in patients with limited education and literacy.

The incidence, causes, mechanism, risk factors, classification, and diagnosis of pelvic fracture urethral injury.

BACKGROUND: Pelvic fracture urethral injury (PFUI) is an uncommon but potentially devastating result of pelvic fracture. It ranges in severity based on the cause and the mechanism of injury. METHODS: We reviewed previous reports to identify the incidence, causes, mechanisms of injury and risk factors of PFUI. In addition, we reviewed the current classification systems and diagnostic methods that have been described to assess the severity of PFUI, to identify optimal management strategies and evaluate outcomes. RESULTS: PFUI occurs more commonly in men, but is more likely to be severe in children. The most common cause is motor vehicle collisions, and the mechanism is typically a ligament rupture at the attachment to the urethra. There is no reliable classification system to differentiate partial and complete PFUI. Retrograde urethrography is the standard imaging method but it has its limitations. CONCLUSIONS: Despite many reports describing this injury, there is still a need to further clarify the incidence, aetiology and mechanism of injury to better determine optimal management strategies and evaluate outcomes. Consensus in the diagnosis of PFUI is lacking, and outcomes of primary realignment and the role of flexible cystoscopy as a diagnostic method are still to be determined.

The incidence of erectile dysfunction after pelvic fracture urethral injury: A systematic review and meta-analysis.

BACKGROUND: Pelvic fracture urethral injury (PFUI) is associated with a high risk of erectile dysfunction (ED). The effect of the type of posterior urethral disruption repair on erectile function has not been clearly established. We systematically reviewed and conducted a meta-analysis of the proportion of patients with ED at (i) baseline after pelvic fracture with PFUI, (ii) after immediate primary realignment, and (iii) after delayed urethroplasty. METHODS: Using search terms for primary realignment or urethroplasty and urethral disruption, we systematically reviewed PubMed and EMBASE. A meta-analysis of the proportion of patients with ED was conducted assuming a random-effects model. RESULTS: Of 734 articles found, 24 met the inclusion criteria. The estimate of the proportion (95% confidence interval) of patients with ED after (i) PFUI was 34 (25-45)%, after (ii) immediate primary realignment was 16 (8-26)%, and after (iii) delayed urethroplasty was an additional 3 (2-5)% more than the 34% after pelvic fracture in this cohort. CONCLUSIONS: After pelvic fracture, 34% of patients had ED. After primary endoscopic alignment, patients had a lower reported rate of ED (16%). Delayed urethroplasty conferred an additional 3% risk above the 34% associated with PFUI alone, with 37% of patients having de novo ED. The difference in de novo ED after primary endoscopic alignment vs. delayed urethroplasty is probably due to reporting differences in ED and/or patients with less severe injury undergoing primary realignment.

Cutaneous Penile Horn.

A 70-year-old man presented with a slowly enlarging glans penis lesion measuring approximately 3 × 2 × 2 cm. On examination, the lesion was indurated with no induration of the glans penis deep to the lesion. He had no palpable lymphadenopathy. A glans sparing surgical excision was performed. Pathology demonstrated a squamoproliferative lesion with hyperkeratosis, and deep margin biopsy demonstrated no carcinoma. Cutaneous penile horns are hyperkeratotic lesions and may be associated with synchronous or metachronous squamous cell carcinoma. Surgical excision remains the mainstay of treatment, and follow-up physical examinations to assess for metachronous penile carcinoma are recommended.

A Drosophila model identifies a critical role for zinc in mineralization for kidney stone disease.

Ectopic calcification is a driving force for a variety of diseases, including kidney stones and atherosclerosis, but initiating factors remain largely unknown. Given its importance in seemingly divergent disease processes, identifying fundamental principal actors for ectopic calcification may have broad translational significance. Here we establish a Drosophila melanogaster model for ectopic calcification by inhibiting xanthine dehydrogenase whose deficiency leads to kidney stones in humans and dogs. Micro X-ray absorption near edge spectroscopy (µXANES) synchrotron analyses revealed high enrichment of zinc in the Drosophila equivalent of kidney stones, which was also observed in human kidney stones and Randall's plaques (early calcifications seen in human kidneys thought to be the precursor for renal stones). To further test the role of zinc in driving mineralization, we inhibited zinc transporter genes in the ZnT family and observed suppression of Drosophila stone formation. Taken together, genetic, dietary, and pharmacologic interventions to lower zinc confirm a critical role for zinc in driving the process of heterogeneous nucleation that eventually leads to stone formation. Our findings open a novel perspective on the etiology of urinary stones and related diseases, which may lead to the identification of new preventive and therapeutic approaches.

Trends, utilization, and immediate perioperative complications of urethroplasty in the United States: data from the national inpatient sample 2000-2010.

OBJECTIVE: To determine national urethroplasty trends based on type of surgery and patient and hospital characteristics. We hypothesized that the number of complex urethroplasty procedures performed has increased over time and may be associated with increased periprocedure complications. METHODS: The National Inpatient Sample from years 2000 to 2010 was queried for patients with urethroplasty-associated International Classification of Diseases, Ninth Revision, Clinical Modification codes. We analyzed trends in urethroplasty procedures, patient demographics, comorbidities, and hospital characteristics. We evaluated the relationship between patient demographics and comorbid disease, length of hospital stay, hospital charges, and inpatient complications. RESULTS: During the study period, an estimated 13,700 men (95% confidence interval, 9507-17,894) underwent urethroplasty nationally. Excision with primary anastomosis, buccal graft, and other graft or flap urethroplasty comprised 80.3%, 14.3%, and 5.4%, respectively. Buccal mucosa graft procedures increased over time (P = .03). Only 1.6% of hospitals have ≥ 20 urethroplasties performed annually. Urethroplasty type and urethroplasty volume were not associated with immediate complication rates. Hypertension, diabetes, chronic pulmonary disease, and obesity were the most common comorbidities in urethroplasty patients. Complications during urethroplasty hospitalization occurred in 6.6% of men, with surgical or wound complications being the most common (5.2%). Postoperative mortality was exceedingly rare. Older patients, African Americans, and patients with increased comorbidities were more likely to have complications. CONCLUSION: An increasing number of buccal mucosa graft urethroplasties occurred over time. Urethroplasty patients have low immediate perioperative morbidity (6.6%) and mortality (0.07%). Patients who are older, African American, or have more comorbid conditions have greater risk for complications.

Lichen Sclerosus Comorbidities and Complications from a National Sample of Patients Treated with Urethroplasty.

INTRODUCTION: We characterize comorbidities and inpatient complications of patients with lichen sclerosus who underwent urethroplasty from a large national patient data source. METHODS: We queried the Nationwide Inpatient Sample for patients who underwent urethroplasty between 2000 and 2010. We compared demographics, comorbidities, complications, length of hospital stay and hospital charges for patients with and without the diagnosis of lichen sclerosus. RESULTS: An estimated 13,700 urethroplasties were performed in the United States during the study period. Patients with lichen sclerosus comprised an estimated 3.8% of the urethroplasty population. The majority of patients with urethral stricture with lichen sclerosus were Caucasian (84%) and older, with 63% age 45 or older. Chronic hypertension, diabetes mellitus, rheumatoid arthritis/collagen vascular disease and obesity were associated with increased odds of having a lichen sclerosus diagnosis. The central East Coast (7.2%) and the Pacific Northwest (6.3%) had the highest percentage of patients treated with urethroplasty with lichen sclerosus. Patients with lichen sclerosus had longer hospital stays than those without lichen sclerosus (3.5 vs 2.6 days, p <0.0001). Patients with lichen sclerosus had more complications and hospital charges than those without lichen sclerosus but these differences did not reach statistical significance. CONCLUSIONS: A higher percentage of patients with lichen sclerosus had comorbidities, increased complications and longer hospital stays compared to patients treated with urethroplasty without lichen sclerosus. Our findings demonstrate the increased complexity that providers face when treating men with lichen sclerosus related urethral stricture disease.

Sports-related genitourinary injuries presenting to United States emergency departments.

OBJECTIVE: To describe epidemiologic features of sports-related genitourinary (GU) injuries and determine patient cohorts and particular sporting activities associated with increased GU injury risk. MATERIALS AND METHODS: The National Electronic Injury Surveillance System, a data set validated to provide a probability sample of injury-related US emergency department (ED) presentations, was analyzed to characterize GU injuries between 2002 and 2010. A total of 13,851 observations were analyzed to derive national estimates. RESULTS: Between 2002 and 2010, an estimated 137,525 individuals (95% confidence interval, 104,490-170,620) presented to US EDs with GU injuries sustained during sporting activities. Nearly three-quarters of injuries occurred in the pediatric population. The most common product involved was a bicycle, representing approximately one-third of injuries in both adult and pediatric populations. Injuries related to team sports such as football, baseball or softball, basketball, and soccer were also common, particularly among boys where they represented a combined third of all injuries. Eighty-nine percent of all patients were evaluated and treated in the ED without inpatient admission. The large majority of injuries involved the external genitalia (60%), and significant injuries of paired GU organs (kidneys and testicles) requiring inpatient admission were rare (8.5%). CONCLUSION: Sports-related GU injuries are most commonly sustained during the use of a bicycle. However, there are other associated activities with identifiable high-risk cohorts, products, and situations. Consumers, practitioners, and injury-prevention experts can use our epidemiologic data to prioritize and develop strategies aimed at the prevention and limitation of such injuries, particularly when counseling at-risk cohorts, such as those with solitary kidneys or testicles.

Artificial urinary sphincter placement in compromised urethras and survival: a comparison of virgin, radiated and reoperative cases.

PURPOSE: Although long-term outcomes after initial placement of artificial urinary sphincters are established, limited data exist comparing sphincter survival in patients with compromised urethras (prior radiation, artificial urinary sphincter placement or urethroplasty). We evaluated artificial urinary sphincter failure in patients with compromised and noncompromised urethras. MATERIALS AND METHODS: We performed a retrospective analysis of 86 sphincters placed at a single institution between December 1997 and September 2012. We assessed patient demographic, comorbid disease and surgical characteristics. All nonfunctioning, eroded or infected devices were considered failures. RESULTS: Of the 86 patients reviewed 67 (78%) had compromised urethras and had higher failure rates than the noncompromised group (34% vs 21%, p=0.02). Compared to the noncompromised group, cases of prior radiation therapy (HR 4.78; 95% CI 1.27, 18.04), urethroplasty (HR 8.61; 95% CI 1.27, 58.51) and previous artificial urinary sphincter placement (HR 8.14; 95% CI 1.71, 38.82) had a significantly increased risk of failure. The risk of artificial urinary sphincter failure increased with more prior procedures. An increased risk of failure was observed after 3.5 cm cuff placement (HR 8.62; 95% CI 2.82, 26.36) but not transcorporal placement (HR 1.21; 95% CI 0.49, 2.99). CONCLUSIONS: Artificial urinary sphincter placement in patients with compromised urethras from prior artificial urinary sphincter placement, radiation or urethroplasty had a statistically significant higher risk of failure than placement in patients with noncompromised urethras. Urethral mobilization and transection performed during posterior urethroplasty surgeries likely compromise urethral blood supply, predisposing patients to failure. Patients with severely compromised urethras from multiple prior procedures may have improved outcomes with transcorporal cuff placement rather than a 3.5 cm cuff.

Reoperative urethroplasty. A systematic review.

OBJECTIVES: Limited articles are published on reoperative urethroplasty outcomes. We sought to perform a systematic review of re-operative urethroplasty articles over the past fifteen years. METHODS: A systematic review was performed on PubMed using the search terms "Urethra" AND "Surgical Procedures, Operative" OR "Urethroplasty". RESULTS: Five articles out of 3,541 articles identified between 1998 and 2012 specifically addressed re-operative urethroplasty patients. A total of 212 patients were included in these five studies. Re-operative urethroplasty success rates ranged from 35% to 84%. Success rates were higher in the two studies with over 40 patients and ranged from 78-84%. CONCLUSION: Limited studies address re-operative urethroplasty outcomes. Success rates for re-operation are lower than those for initial urethroplasty procedures. Overall, studies with a higher number of patients had an increased success rate.

The association of lower urinary tract symptoms, depression and suicidal ideation: data from the 2005-2006 and 2007-2008 National Health and Nutrition Examination Survey.

PURPOSE: We examine the association among depression, suicidal ideation and self-reported lower urinary tract symptoms using a large, cross-sectional, population based study. MATERIALS AND METHODS: The study included 2,890 men from the 2005-2006 or 2007-2008 cycles of the NHANES (National Health and Nutrition Examination Survey) who were 40 years old or older. Men were asked if they experienced nocturia, urinary hesitancy and/or incomplete bladder emptying. The PHQ-9 (Patient Health Questionnaire-9) was used to determine the likelihood of clinical depression and suicidal ideation. RESULTS: The prevalence of lower urinary tract symptoms was 33.7% and 10.3% for men reporting 1 and 2 or more symptoms, respectively. Moderate to severe depression (PHQ-9 score 10 or greater) and suicidal ideation were reported by 181 (6.3%) and 105 (3.6%) men, respectively. Men reporting moderate to severe depression (compared to those reporting minimal depression) had a higher odds of reporting lower urinary tract symptoms (adjusted odds ratio [AOR] 5.09, 95% CI 3.17-8.17 for PHQ-9 score 5 to 9 and AOR 7.62, 95% CI 3.90-14.87 for PHQ-9 score 10 or greater; p trend <0.0001). More lower urinary tract symptoms were associated with a significantly higher odds of moderate to severe depression (AOR 3.09, 95% CI 1.86-5.15 for 1 symptom and AOR 8.06, 95% CI 4.18-15.53 for 2 or more symptoms, p trend <0.0001) and a higher odds of suicidal ideation (AOR 1.70, 95% CI 0.85-3.42 and AOR 2.71, 95% CI 1.40-5.25, respectively, p trend = 0.004). CONCLUSIONS: A significant relationship was observed between lower urinary tract symptoms and depression/suicidal ideation. While the pathophysiology of the relationship and its significance in clinical practice remain unclear, clinicians may consider screening men with severe lower urinary tract symptoms for depression.

Selective angioembolization for traumatic renal injuries: a survey on clinician practice.

PURPOSE: A variety of clinical and imaging findings are used by clinicians to determine utility of renal angioembolization (AE) in managing renal trauma. Our purpose was to investigate specific criteria that clinicians who manage high-grade renal trauma (HGRT) utilize in decision-making for primary or delayed AE. METHODS: A total of 413 urologists and interventional radiologists (IRs) who practice at level 1 or 2 trauma centers within the United States were provided an original survey via email on experience and opinions regarding the utility of AE for HGRT. We described overall practice patterns and assessed differences by clinician type, using the Fisher's exact test. RESULTS: A total of 79 (20 %) clinicians completed the survey. All clinicians had AE capability for HGRT management. A higher proportion of IRs reported using AE for grade I-II (33 vs. 3 %, p = 0.002), grade III (65 vs. 26 %, p = 0.001), and penetrating injuries (83 vs. 58 %, p = 0.02). A greater proportion of urologists reported using AE for grade V injuries (81 vs. 56 %, p = 0.03). Clinicians most commonly cited computed tomography evidence of active arterial bleeding (97 %), or arteriovenous fistula/pseudoaneurysm (94 %) as indications for primary AE, and 62 % identified concurrent visceral injury as factor that would necessitate surgical intervention. CONCLUSION: In a survey of clinicians, we report that IRs and urologists utilize AE differently when managing HGRT, as a higher proportion of IRs use AE to manage lower grade as well as penetrating injuries. Validation studies are needed to establish algorithms to identify patients with HGRT who would benefit from selective renal AE.

Epidemiology of urethral strictures.

Urethral stricture disease is relatively common and is associated with a significant financial cost and potentially debilitating outcomes. Understanding urethral stricture epidemiology is important to identify risk factors associated with the etiology or progression of the disease. This understanding may lead to better treatments and preventative measures that could ameliorate disease severity, produce better health outcomes, and reduce expenditures. We performed a comprehensive review of urethral stricture disease based on available published case series, identified gaps in knowledge of this disease, and recommend future directions for research.
