Abstract Introduction: To investigate the impact of facility type and volume on survival in patients with metastatic renal cell carcinoma (mRCC).
Materials and methods: We investigated the National Cancer Database for patients with mRCC. Patients were stratified according to treatment facility type (academic vs. non-academic) and facility volume (high, intermediate, and low). Kaplan-Meier survival estimates and Cox proportional hazard models were fitted to evaluate overall survival (OS) as a function of facility type, volume, and different treatment modalities.
Results: A total of 27,598 patients were identified, of which 10,938 (40%) were treated at academic centers (AC) and 16,131 (60%)… More >

Abstract Introduction: We aim to investigate if the addition of MRI-US fusion biopsy (FB) can aid in radiation planning and alter the boost field in cases of stereotactic body radiation therapy (SBRT) for prostate cancer with a simultaneous integrated boost (SIB) to a magnetic resonance imaging (MRI)-defined intraprostatic lesion.
Materials and methods: Patients undergoing SBRT with SIB for biopsy-proven prostatic adenocarcinoma and a pre-radiation MRI were retrospectively reviewed. 36.25 Gy in 5 fractions was delivered to the entire prostate along with SIB of 40 Gy to an MRI-defined intraprostatic lesion. Demographic, radiation planning details, and post-procedural outcomes were… More >

Abstract Introduction: Half of men aged > 60 years will develop benign prostatic hyperplasia (BPH) with 40% of these men having moderate-to-severe lower urinary tract symptoms (LUTS). There is limited knowledge on a head-to-head comparison of prostatic urethral lift (UroLift) and convective water vapor ablation (Rezum) for the treatment of LUTS secondary to BPH. We sought to compare randomized controlled trials with 3-year clinical outcome data.
Materials and methods: After a thorough literature search, two multicenter sham-controlled double-blind randomized trials for UroLift and Rezum were identified and compared. Both studies had similar designs, baseline characteristics, reported outcomes, and… More >

Abstract Introduction: To better understand how the COVID-19 pandemic has forced rapid operational changes in the global healthcare industry, changes implemented on an individual, institutional basis must be considered. There currently is not adequate literature about the overall impact COVID-19 has had on pediatric urology services worldwide. We believe that they have dramatically decreased during the COVID-19 crisis, but have adapted to accommodate changes. We hypothesize that patient care was widely variant due to inadequate standardized recommendations or crisis planning.
Materials and methods: A web-based survey was deployed to 377 pediatric urologists globally via email to analyze COVID-19’s… More >

Abstract Introduction: Obstructing stones with infection represent a true urologic emergency requiring prompt decompression. Historically, the systemic inflammatory response syndrome (SIRS) criteria has been used to predict outcomes in patients with sepsis. The quick Sequential Organ Failure Assessment (qSOFA) score has been proposed as a prognostic factor in patients with acute pyelonephritis associated with nephrolithiasis. However, there has been limited application of qSOFA to patients undergoing ureteral stenting with obstructive pyelonephritis. The purpose of this study was to evaluate the predictive value of the qSOFA score for postoperative outcomes following renal decompression in this patient population.

Abstract Introduction: Following kidney transplantation, lymphoceles can impact patient and graft outcomes, while resulting in significant hospital resource utilization. We aimed to characterize the incidence, risk factors, outcomes, and clinical management of lymphoceles among kidney transplant recipients and review impact on health system utilization at a high-volume center.
Materials and methods: We conducted a single-center, observational cohort study on adults transplanted between January 1, 2005 and December 31, 2017. Incidence, risk factors, and clinical outcomes were assessed using the Kaplan-Meier product-limit method, multivariable logistic regression model, and Cox proportional hazards model, respectively.
Results: Lymphoceles developed in 72 of 1881… More >

Abstract Introduction: Placement of coudé catheters, manual irrigation of urinary catheters, and management of continuous bladder irrigation (CBI) are routine interventions for which nurses often receive little or no formal education. In this study, our aim was to determine factors associated with higher comfort levels for these catheter-care techniques and to assess whether online instructional videos could be used to improve nursing comfort.
Materials and methods: Three 5-minute videos were created to demonstrate proper technique for coudé catheter placement, manual irrigation of a catheter, and management of CBI. An online module with pre- and post-video surveys was created… More >

Abstract Introduction: Ureteroscopy and laser lithotripsy is a common treatment option for upper urinary tract calculi. Currently, ureteral stents are placed after uncomplicated ureteroscopy for up to 1 week, but the optimal length of placement is not well defined. Ureteral stents are associated with significant morbidity, particularly stent discomfort. This study aims to determine differences in postoperative unplanned clinic or ED visits based on duration of stent placement.
Materials and methods: This is a single-institution, IRB-approved, retrospective cohort study of 559 ureteroscopy cases with laser lithotripsy for urinary tract calculi performed from 2016 to 2018. The primary outcome… More >

Abstract Development of chronic postsurgical pain following major abdominal or pelvic surgeries is increasingly recognized. Multimodal analgesia including regional anesthesia such as rectus sheath block is growing in popularity. While the literature mainly describes ultrasound-guided rectus sheath blocks, there are many advantages to surgicallyinitiated rectus sheath catheter performed at the end of surgery. In this technical description, we describe the rationale and technique of surgical insertion of rectus sheath catheters following major urologic surgery with midline incision which is routinely performed by urologists at our institution. Furthermore, we would like to highlight the type of catheter More >

Abstract 3D printing has been growing in many surgical fields including Urology. The primary use has been to print kidneys with tumors to better understand anatomy and to assist with surgical planning and education. Previous studies that utilized 3D printing of kidneys for partial nephrectomies have been limited by the cost and complexity of model creation, rendering them highly impractical to be used on a routine basis. Using a simpler and more cost-effective design and materials allow the 3D kidney models to be used in a wider range and number of patients. We describe our streamlined More >
