INTRODUCTION: Chronic epididymitis imposes significant physical and psychosocial distress on affected patients. Despite being a commonly encountered urologic condition, there remains a paucity of understanding and literature surrounding the management and natural history of isolated epididymal pain. Typically, patients who do not respond to conservative management undergo an epididymectomy.; however, the literature on its efficacy is also scarce, with success rates varying widely from 10-90% in existing studies...

INTRODUCTION: Most robot-assisted surgery (RAS) systems in Canada are donor-funded, with constraints on implementation and access due to significant costs, among other factors. Herein, we evaluated the impact of the growing multispecialty use of RAS on urologic RAS access and outcomes in the past decade. METHODS: We conducted a retrospective review of all RAS performed by different surgical specialties in two high-volume academic hospitals between 2010 and 2019 (prior to the COVID pandemic)...

INTRODUCTION: Neoadjuvant chemotherapy (NAC) is the standard of care for patients undergoing radical cystectomy (RC) for muscle-invasive bladder cancer (MIBC); however, NAC can be associated with significant side effects and morbidity in some patients. NAC may contribute to sarcopenia, obesity, and the combination of the two. Our study examined the effects of NAC on body composition and the association between body composition and adverse events. METHODS: We created a retrospective database of patients with non-metastatic MIBC receiving NAC prior to RC...

INTRODUCTION: Patients undergoing radical nephrectomy (RN) are often admitted with protocolized bloodwork for several days following their operation, yet the clinical value of serial hemoglobin (Hgb) measurements has not been established. This can lead to unnecessary costs and can prolong patient stay, despite the absence of an intervention based on these lab values. This study sought to examine perioperative Hgb values and identify those patients at high risk of bleeding requiring intervention, as well as those patients who are unlikely to require further monitoring...

Allopurinol is a commonly prescribed agent in the urologic population for the prevention of urinary stones. Although generally well-tolerated, several serious potential side effects can occur with its use. Allopurinol hypersensitivity syndrome (AHS), in particular, is a relatively rare but potentially life-threatening complication. With the observed increase in urinary stone disease, especially those of uric acid composition, it is likely that the use of allopurinol will increase. Urologists play an important role in the assessment and medical management of patients with urinary stones, thus a greater awareness of the potential adverse events associated with allopurinol use, especially AHS, is important, as well as strategies that can minimize such risks...

INTRODUCTION: We aimed to clarify the therapeutic outcome of combination therapy using immune-checkpoint inhibitors (ICIs) and/or tyrosine kinase inhibitors (TKIs) for metastatic non-clear-cell renal cell carcinoma (nccRCC). METHODS: We have been retrospectively investigating the therapeutic efficacy and prognosis in 36 patients with metastatic nccRCC undergoing combination therapy using two ICIs, ipilimumab plus nivolumab (ICI-ICI), and ICI plus TKI (ICI-TKI), at Kobe University and affiliated institutions since 2018...

INTRODUCTION: There has been a rapid expansion of the armamentarium for managing benign prostatic hyperplasia (BPH). Given the invasiveness and complication risks of traditional surgical management, minimally invasive procedures have emerged. Rezūm water vapour therapy is a safe, effective alternative. Given the minimally invasive nature, there is interest in administering conscious sedation over general anesthesia (GA) to decrease procedural times and costs and increase accessibility by completing procedures in an office-based setting...

INTRODUCTION: Gender inequality has been prevalent in the history of medicine, specifically within surgical specialties. Though there have been advances, urology has remained overwhelmingly male-dominant, with slow growth in female recruitment. This survey study evaluated whether gender-related differences in the perception of urology are present among future applicants that could account for gender disparity seen in recruitment. METHODS: An anonymized, online survey was distributed to medical students enrolled at the Max Rady College of Medicine during the 2022- 2023 semester...

INTRODUCTION: The completion of residency and start of fellowship training marks a critical transition for urologists in the pursuit of subspeciality training. Most graduating urology residents are under contract until June 30, and the majority of fellowships are scheduled to begin on July 1. There has been no investigation into the practical implications of fellowship delays in urology from a trainee perspective. Our research study aims to investigate the incidence and predictors of delays in fellowship starts...

INTRODUCTION: Combined systematic plus targeted biopsy sampling improves detection of clinically significant prostate cancer (PCa). Our objective was to evaluate whether extended core sampling at initial biopsy in active surveillance (AS) patients is associated with subsequent AS discontinuation and pathologic outcomes. METHODS: National Comprehensive Cancer Network (NCCN) low- and favorableintermediate-risk (FIR) AS patients diagnosed between 2010 and 2015 were identified from the Surveillance, Epidemiology, and End Results (SEER) Prostate with Watchful Waiting database...

INTRODUCTION: Female stress urinary incontinence (SUI) is common and has a profound impact on quality of life. Suburethral slings are the most common treatment for SUI in this population. These can be placed with synthetic mesh or autologous fascia. Mesh-related complications after midurethral sling procedures are documented in the literature but the risk of complications and reoperation is lower than the use of transvaginal mesh for pelvic organ prolapse repair. In this study, we sought to evaluate local practice patterns of management of female SUI with specific emphasis on mesh use...

INTRODUCTION: To improve the prediction of outcomes in patients who will undergo radical nephroureterectomy (RN U) for upper tract urothelial carcinoma (UTUC), we investigated the preoperative prognostic factors and developed a risk classification model. METHODS: A total of 144 patients who underwent RNU with history of neither neoadjuvant nor adjuvant chemotherapy between 2008 and 2022 were retrospectively reviewed. Associations between perioperative/clinicopathologic factors and outcomes, including cancer-specific survival (CSS), were assessed...
