PURPOSE Provider and hospital factors influence healthcare quality, but data are lacking to assess their impact on renal cancer surgery. We aimed to assess factors related to surgeon and hospital volume and study their impact on 30-day outcomes after radical nephrectomy. MATERIALS AND METHODS Renal surgery data were abstracted from Maryland's Health Service Cost Review Commission from 2000 to 2018. Patients ≤18 years old, without a diagnosis of renal cancer, and concurrently receiving another ma...

Neoadjuvant immune checkpoint blockade represents a novel approach for potentially decreasing the risk of recurrence in patients with nonmetastatic renal cell carcinoma (RCC). In this early phase clincal tiral, we evaluated the safety and tolerability of neoadjuvant treatment with the programmed cell death protein 1 (PD-1) inhibitor nivolumab in patients with nonmetastatic high-risk RCC. Nonprimary endpoints included objective radiographic tumor response rate, immune-related pathologic response ...

Abstract In this report we describe our successful adoption of a single-use, probe-mounted, needle guide for perirectal hydrogel spacer placement prior to radiation therapy for prostate cancer. Use of this device eliminates the need for a mechanical stepper unit and facilitates perirectal hydrogel placement by ensuring alignment of the injection needle with the ultrasound probe.

Abstract Objective To evaluate outcomes for patients with local recurrence (LR) of clinically localized renal cell carcinoma (RCC) without concurrent systemic metastasis from our institution, an event that occurs rarely (1-3%) after surgery. LR may be a harbinger of poor outcomes, and the best management of these patients is unclear. Materials/Methods We retrospectively reviewed patients surgically treated for clinically localized RCC (cT1-2N0M0) with subsequent LR (in the partial or radical nep...

The objectives were to evaluate the safety and oncologic efficacy of primary robotic retroperitoneal lymph node (R-RPLND) dissection for testicular germ cell tumors. A retrospective analysis was performed on all primary R-RPLND cases performed by a single surgeon, who performs both open and R-RPLND at a high-volume academic institution, between August 2013 and August 2019. Data on patient demographics, operative techniques, perioperative outcomes, and tumor characteristics were obtained. 28 men ...

Clinical guidelines have conflicting recommendations on the role of prostate artery embolization (PAE), a novel interventional radiology technique used to treat benign prostatic hyperplasia (BPH). In the absence of consensus among clinicians, patients may seek information online, where consumer-targeted content has proliferated in recent years. Our objective was to assess the content and quality of online information about prostate artery embolization (PAE). We evaluated patient interest and exp...

INTRODUCTION [111 In]In-XYIMSR-01 is a promising single-photon emission computed tomography (SPECT) imaging agent for identification of tumors that overexpress carbonic anhydrase IX. To translate [111 In]In-XYIMSR-01 to phase I trials, we performed animal toxicity and dosimetry studies, determined the maximum dose for human use, and completed the chemistry, manufacturing, and controls component of a standard regulatory application. METHODS The production process, quality control testing, stabili...

OBJECTIVE To evaluate perioperative complications for open and robotic-assisted RP for patients enrolled in the PREVENTER trial to determine predictors and impact on opioid consumption. PATIENTS AND METHODS A prospective cohort of 500 patients undergoing open and robotic-assisted RP were followed to determine rates of complications and opioid use. Complications were classified 30 days post-RP using the Clavien-Dindo system. Patient characteristics and outcomes were compared using appropriate sta...
