Development and Validation of a Multivariable Nomogram Predictive of Post-Nephroureterectomy Renal Function.

Background And Objective: The timing of perioperative nephrotoxic chemotherapy for upper tract urothelial carcinoma (UTUC) remains controversial and strongly depends on predicted platinum eligibility after radical nephroureterectomy (RNU). The study objective was to develop and validate a multivariable nomogram to predict estimated glomerular filtration rate (eGFR) following RNU.

Methods: This was a multi-institutional retrospective study of patients with UTUC treated with RNU from 2000 to 2020 at seven high-volume referral centers.

Neoadjuvant Atezolizumab With Gemcitabine and Cisplatin in Patients With Muscle-Invasive Bladder Cancer: A Multicenter, Single-Arm, Phase II Trial.

Purpose: Neoadjuvant gemcitabine and cisplatin (GC) followed by radical cystectomy (RC) is standard for patients with muscle-invasive bladder cancer (MIBC). On the basis of the activity of atezolizumab (A) in metastatic BC, we tested neoadjuvant GC plus A for MIBC.

Methods: Eligible patients with MIBC (cT2-T4aN0M0) received a dose of A, followed 2 weeks later by GC plus A every 21 days for four cycles followed 3 weeks later by a dose of A before RC.

Tandem Resonance metallic double-J ureteral stents in a single ureter for salvage management of chronic ureteral obstruction.

For chronic malignant and benign ureteral obstruction, the metal construction of the Resonance ureteral stent has been developed to maintain ureteral patency for up to 12 months, obviating the need for the frequent exchange required for conventional plastic ureteral stents. We report our experience placing tandem Resonance stents (TRS) in a single ureter of patients who failed management with a single Resonance stent. A retrospective review of patients who had TRS for management of ureteral obstruction between February 2014 and May 2017 was performed.

Preoperative ureteral stenting prior to ureteroscopy for management of urolithiasis does not impact the postoperative return for unplanned care.

Introduction: Return for unplanned postoperative care is an important quality metric in the United States. Most of our postoperative return visits occur after ureteroscopy. Routine preoperative ureteral stenting is not recommended by the American Urological Association due to its impact on the quality of life, despite its proposed operative advantages.

Interactions between benign prostatic hyperplasia (BPH) and prostate cancer in large prostates: a retrospective data review.

Purpose: To study the interaction between benign prostatic hyperplasia (BPH) and prostate cancer (PCa).

Methods: In this study, we performed a chart review of a cohort of 448 biopsy naive men. These men received a multi-core biopsy at our institution due to increased prostate-specific antigen (PSA) serum levels (>4 ng/ml) and/or suspicious findings on digital rectal examination in the years between 2008 and 2013.
