Impact of surgical volume and resident involvement on patency rates after vasectomy reversal-A 14-year experience in an open access system.

OBJECTIVE: Evaluate the influence of fellowship training, resident participation, reconstruction type, and patient factors on outcomes after vasectomy reversals in a high volume, open access system. METHODS: Retrospective review of all vasectomy reversals performed at a single institution from January 1, 2002 to December 31, 2016 was conducted. Patient and spouse demographics, patient tobacco use and comorbidities, surgeon training and case volume, resident participation, reconstruction type, and postoperative patency were collected and analyzed. RESULTS: Five hundred and twenty-six vasectomy reversals were performed during the study period. Follow-up was available in 80.6% of the cohort and overall patency, regardless of reconstruction type was 88.7%. The mean time to reversal was 7.87 years (range of 0-34 years). The majority of cases included resident participation. Case volume was high with faculty and residents logging a mean of 37.0 and 38.7 (median 18 and 37) cases respectively. Bilateral vasovasostomy was the most common reconstruction type (83%) and demonstrated a significantly better patency rate (89%) than all other reconstructions (p=0.0008). Overall patency and patency by reconstruction type were not statistically different among faculty surgeons and were not impacted by fertility fellowship training, resident participation or post-graduate year. Multivariate analysis demonstrated that increased time to reversal and repeat reconstructions had a negative impact on patency (p=0.0023 and p=0.043, respectively). CONCLUSIONS: Surgeons with a high volume of vasectomy reversals have outcomes consistent with contemporary series regardless of fellowship training in fertility. Patency was better for bilateral vasovasostomies. Patency was not negatively impacted by tobacco use, comorbidities, resident participation, or post-graduate year.

Outcomes after Robotic-assisted Pyeloplasty in Patients Presenting with Pain Versus Nonpain Presenting Symptoms.

OBJECTIVE: To assess the impact of presenting symptom or incidental finding on symptomatic and radiographic outcomes after robotic-assisted pyeloplasty (RAP). METHODS: We retrospectively reviewed the records of 143 patients at our institution who received pyeloplasty from 2001-2017. Patients without both pre- and postoperative radiographic data were excluded. Patients were grouped by primary presenting symptom into either pain at presentation (pain) or nonpain primary presenting symptom, including incidental findings (nonpain). Primary outcomes were persistence of postoperative symptoms and improvement in diuretic renogram half-times. RESULTS: The study inclusion criteria was met by 105 patients. Pain was the most common presenting symptom (70.0%), followed by incidental finding (10.5%), infection (7.6%), hematuria (4.8%), hypertension (2.8%), elevated creatinine (2.8%), and nausea (1.0%). Patients with nonpain presentations were significantly more likely to have postoperative symptoms (P = .04), and less likely to improve on diuretic renogram (P = .03). Incidental presentation was found to be associated with greater likelihood of persistent postoperative symptoms compared with other presentations (36.3% vs 8.5%, P = .02). CONCLUSION: Ureteropelvic junction obstruction (UPJO) patients presenting with pain, experience better symptom and radiographic improvement following RAP compared with patients presenting without pain. Incidental UPJO was the most common nonpain presentation and is associated with less symptomatic and radiographic benefit after RAP. These findings will help reconstructive urologists counsel patients with UPJO regarding outcomes of RAP.

Inconsistency in the Definition of Urinary Tract Infection after Intravesical Botulinum Toxin A Injection: A Systematic Review.

PURPOSE: To more accurately examine the rate of urinary tract infection following onabotulinumtoxinA injection of the bladder we systematically reviewed the literature for definitions of urinary tract infection in studies of onabotulinumtoxinA injections. We assessed the studies for consistency with guideline statements defining urinary tract infections. MATERIALS AND METHODS: We systematically reviewed the literature by querying MEDLINE® and Embase®. We included original studies on adult patients with idiopathic overactive bladder and/or neurogenic detrusor overactivity who underwent cystoscopy with onabotulinumtoxinA injection and in whom urinary tract infection was a reported outcome. RESULTS: We identified 299 publications, of which 50 met study inclusion criteria. In 27 studies (54%) urinary tract infection diagnostic criteria were defined with a total of 10 definitions among these studies. None of the overactive bladder studies used a definition which met the EAU (European Association of Urology) criteria for urinary tract infection. Only 2 of the 10 studies on patients with neurogenic bladder used a urinary tract infection definition consistent with the NIDRR (National Institute on Disability and Rehabilitation Research) standards. CONCLUSIONS: Definitions of urinary tract infection are heterogeneous and frequently absent in the literature on onabotulinumtoxinA to treat overactive bladder and/or neurogenic bladder. Given the potential for post-procedure urinary symptoms in this setting, explicit criteria are imperative to establish the true urinary tract infection rate following treatment with onabotulinumtoxinA.

A decision aid versus shared decision making for prostate cancer screening: results of a randomized, controlled trial.

INTRODUCTION: Shared decision making (SDM) is widely encouraged by both the American Urological Association and Choosing Wisely for prostate cancer screening. Implementation of SDM is challenging secondary to time constraints and competing patient priorities. One strategy to mitigate the difficulties in implementing SDM is to utilize a decision aid (DA). Here we evaluate whether a DA improves a patient's prostate cancer knowledge and affects prostate-specific antigen (PSA) screening rates. MATERIALS AND METHODS: Patients were randomized to usual care (UC), DA, or DA + SDM. Perception of quality of care was measured using the Consumer Assessment of Healthcare Providers and Systems (CAHPS) survey. Outcomes were stratified by long term provider relationship (LTPR, > 3 years) versus short term provider relationship (STPR, < 3 years). Knowledge of prostate cancer screening and the decision regarding screening were assessed. Groups were compared using ANOVA and logistic regression models. RESULTS: A total of 329 patients were randomized. Patients in the DA + SDM arm were significantly more likely to report discussing the implication of screening (33% DA + SDM, 22% UC, 16% DA, p = 0.0292) and answered significantly more knowledge questions correctly compared to the UC arm (5.03 versus 4.46, p = 0.046). However, those in the DA arm were significantly less likely to report that they always felt encouraged to discuss all health concerns (72% DA, 78% DA + SDM, 87% UC, p = 0.0285). Interestingly, STPR patients in the DA arm were significantly more likely to undergo PSA-based prostate cancer screening (41%) than the UC arm (8%, p = 0.019). This effect was not observed in the LTPR group. CONCLUSIONS: Providing patients a DA without a personal interaction resulted in a greater chance of undergoing PSA-based screening without improving knowledge about screening or understanding of the consequences of this decision. This effect was exacerbated by a shorter term provider relationship. With complex issues such as the decision to pursue PSA-based prostate cancer screening, tools cannot substitute for direct interaction with a trusted provider.

Urologic Dermatology: a Review.

PURPOSE OF REVIEW: Genital dermatology represents a challenge to many providers. Though dermatologic lesions involving the genitalia may present to any of a number of practices, ranging from primary care to urology, gynecology, and dermatology, few training programs provide significant training regarding the diagnosis and management of genital dermatologic lesions. The purpose of this review is to provide urologists with an overview of common genital dermatological lesions that may be encountered in a clinic. The review also provides a guide to how to approach these conditions. RECENT FINDINGS: This manuscript summarizes the most common categories of genital dermatologic lesions, starting with normal variants and progressing to a review of contagious conditions, premalignant lesions, and malignant lesions. In cases in which a lesion does not definitively belong to one of these categories, an algorithmic approach to making a diagnosis may be helpful to narrow the differential diagnosis. The most common benign genital growths include cysts, syringomas, seborrheic keratosis, pearly papules, and Fordyce spots. Contagious lesions, such as herpes, syphilis, scabies, or molluscum contagiosum, should be treated immediately before complications or transmission can occur. Inflammatory genital lesions are very diverse in etiology and presentation but are the most common genital lesions in urological clinical practice. This category of lesions can be approached by dividing them into non-erythematous and erythematous (scaling and non-scaling) lesions. Given the potential evolution of the challenging category of premalignant genital lesions, proper recognition and early biopsy play an important role. Premalignant lesions can be broadly classified into two categories: those not related to HPV infection and those that are related to HPV, including erythroplasia of Queyrat (EQ), Bowen's disease, Bowenoid papulosis, vulvar intraepithelial neoplasia (VIN), and giant condyloma. Herein, contemporary nomenclature and proper evaluation and management of premalignant lesions are reviewed which provide safe and efficacious outcomes for patients. Finally, malignant genital lesions, though rare, must be recognized early and addressed correctly. Squamous cell carcinoma represents 95% of penile and approximately 90% of vulvar and vaginal malignancies, and diagnosis and management can be challenging and require proper referral to an oncologist. Genital dermatology is a challenging field marked by diagnostic difficulty and management challenges. This manuscript provides an overview of genitourinary dermatologic lesions in an effort to provide clinicians with a framework with which to approach the evaluation of these various conditions that will facilitate proper consideration of the differential diagnoses and help the urologist distinguish between normal, benign, premalignant, and malignant lesions.

The calm mouse: an animal model of stress reduction.

Chronic stress is associated with negative health outcomes and is linked with neuroendocrine changes, deleterious effects on innate and adaptive immunity, and central nervous system neuropathology. Although stress management is commonly advocated clinically, there is insufficient mechanistic understanding of how decreasing stress affects disease pathogenesis. Therefore, we have developed a "calm mouse model" with caging enhancements designed to reduce murine stress. Male BALB/c mice were divided into four groups: control (Cntl), standard caging; calm (Calm), large caging to reduce animal density, a cardboard nest box for shelter, paper nesting material to promote innate nesting behavior, and a polycarbonate tube to mimic tunneling; control exercise (Cntl Ex), standard caging with a running wheel, known to reduce stress; and calm exercise (Calm Ex), calm caging with a running wheel. Calm, Cntl Ex and Calm Ex animals exhibited significantly less corticosterone production than Cntl animals. We also observed changes in spleen mass, and in vitro splenocyte studies demonstrated that Calm Ex animals had innate and adaptive immune responses that were more sensitive to acute handling stress than those in Cntl. Calm animals gained greater body mass than Cntl, although they had similar food intake, and we also observed changes in body composition, using magnetic resonance imaging. Together, our results suggest that the Calm mouse model represents a promising approach to studying the biological effects of stress reduction in the context of health and in conjunction with existing disease models.
