Retroperitoneal Hygroma.

We present a 46-year-old white male with a retroperitoneal hygroma protruding from the right flank.

Efficacy of percutaneous cryoablation of renal cell carcinoma in older patients with medical comorbidities: Outcome study in 70 patients.

Introduction: The aim of this study was to establish the efficacy of cryoablation for incidentally discovered small renal cell carcinomas in older patients with medical comorbidities.

Methods: We carried out a retrospective chart analysis of outcomes of 70 patients treated by cryoablation. The inclusion criteria were age >56 years, medical comorbidities (Charlson class I-III), and suitability for cryoablation established by urologists and interventional radiologists.

Secondary pelvic congestion syndrome: description and radiographic diagnosis.

Introduction: Pelvic congestion syndrome (PCS) is a complex condition of the pelvic venous system leading to nonspecific pelvic pain that was initially described in females alone. The underlying abnormalities, though diverse, all result in increased pressure in the left gonadal vein which is transmitted retrograde into the pelvic venous system. Our primary aim was to describe our findings of secondary PCS as a distinct entity from primary PCS in that it has an identifiable vascular etiology and is gender nonspecific.

Percutaneous radiologic gastrostomy: results and analysis of factors contributing to complications.

Unlabelled: INTENT: Assessment of feasibility of percutaneous radiologic gastrostomy (PRG) for long- or short-term nutritional support and analysis of attendant complications and their underlying causes.

Materials And Methods: A retrospective analysis of outcome, complications, and their underlying causes was carried out in 391 patients who had percutaneous gastrostomies performed in two different university medical centers from January 2005 to April 2010 by interventional radiology. Forty-three were performed under general anesthesia and 348 were under local anesthesia and conscious sedation; in 349, fluoroscopic guidance was used, in 17 ultrasound, and in 22 CT.

Long-term results of metallic stents for malignant ureteral obstruction in advanced cervical carcinoma.

Purpose: We present our experience with the use of metallic stents (Wallstents®) in the management of malignant ureteral obstruction to maintain renal function, thereby permitting the use of chemotherapeutic agents to treat the underlying malignancy.

Patients And Methods: We retrospectively reviewed the records of 24 patients with ureteral obstruction secondary to advanced cervical carcinoma, stage T3b (n=10) and T4 (n=14), that was relieved by Wallstents. Nineteen patients needed bilateral and 5 needed unilateral Wallstents to relieve the obstruction.

Diagnosis, evaluation and follow-up of asymptomatic microhematuria (AMH) in adults: AUA guideline.

Purpose: The purpose of this guideline is to provide a clinical framework for the diagnosis, evaluation and follow-up of asymptomatic microhematuria.

Materials And Methods: A systematic literature review using the MEDLINE® database was conducted to identify peer reviewed publications relevant to the definition, diagnosis, evaluation and follow-up for AMH. The review yielded 191 evidence-based articles, and these publications were used to create the majority of the guideline statements.

The fate of small renal masses, less then 1 cm size: outcome study.

Purpose: We evaluated the outcome and etiologies of small renal masses (less than 1 cm in size) discovered incidentally on 2 consecutive CTs that investigated nonurologic abdominal complaints.

Materials And Methods: A retrospective search for incidentally discovered small renal masses, less then 1 cm in size, was carried out in the files of 6 major US medical centers. 4822 such lesions had been reported over a 12 year period.
