Predicting long‑term survival following involved site radiotherapy for oligometastases.

The majority of cancer-associated mortalities are due to distant metastases, and systemic therapy alone is generally not curative. Patients with oligometastases are amenable to involved site radiotherapy with the possibility of long-term disease-free survival; however, prognostic factors remain poorly defined. The present retrospective, single institution study consisted of consecutive adult patients with oligometastases from solid tumor malignancy referred to a single high volume radiation oncologist between January 2014 and December 2021.

Multiparametric prostate MRI-based intensity-modulated radiation therapy guided by prostatic calcifications.

Objectives: The optimal technique to administer image-guided radiation therapy for prostate cancer remains poorly defined. This study assessed outcomes after multiparametric prostate MRI-based planning was delivered with image-guided radiation therapy using prostatic calculi observed on cone beam CT (CBCT).

Methods: Between January 2015 and December 2017, 94 consecutive patients were treated with CBCT-based image-guided radiation therapy (IGRT) without fiducial markers.

Low-Dose (10%) Computed Tomography May Be Inferior to Standard-Dose CT in the Evaluation of Acute Renal Colic in the Emergency Room Setting.

Introduction: Noncontrast CT is the standard of care to evaluate nephrolithiasis. We evaluated the performance of low-dose CT (LDCT) scan for evaluation of renal colic in the emergency room (ER).

Materials And Methods: Patients visiting the ER with suspected nephrolithiasis received a standard-dose CT (SDCT) and an LDCT.

Body mass index predicts outcome of ureteroscopy-assisted retrograde nephrostomy for percutaneous nephrolithotomy.

Introduction: Several clinical series of retrograde nephrostomy for percutaneous nephrolithotomy (PCNL) have been published over the past 30 years demonstrating good outcomes and safety. We previously reported our adaptation of the Lawson technique, wherein we deploy the puncture wire through a flexible ureteroscope. We herein aim to clarify the performance characteristics of this nephrostomy creation technique.

"Extreme" renal preservation: neoadjuvant chemotherapy and percutaneous resection for upper-tract urothelial carcinoma in a patient with solitary kidney--a case report.

Background And Purpose: Renal preservation in selected patients with upper-tract urothelial cancer (UTUC) has been well described, offering an alternative to radical nephroureterectomy. We present our experiences in performing percutaneous treatments after neoadjuvant chemotherapy in one such patient with a large, complex, high-grade UTUC in a solitary kidney.

Case Report: A 55-year-old woman with a solitary kidney presented with a 5.
