Two Cases of Strictures after Percutaneous CT-Guided Radiofrequency Ablation for Renal Cell Carcinoma.

Percutaneous radiofrequency ablation is a safe and effective minimally invasive treatment option in selected patients with T1a tumors of the kidney with a low complication rate. We describe two cases that developed the rare but severe complication of thermal injury-induced strictures of the upper urinary tract and its consecutive management.

Can a Simple Geriatric Assessment Predict the Outcome of TURP?

Purpose: To determine the impact of a simple preoperative geriatric assessment on the outcome in older patients with recurrent urinary retention who underwent desobstructive surgery.

Patients And Methods: Patients aged 75 years or older with recurrent urinary retention referred for TURP entered this prospective, multicentre study. Several demographic, intra- and postoperative parameters were assessed.

Renal Papillary Hyperplasia as a Cause of Persistent Asymptomatic Microhematuria.

Asymptomatic microscopic hematuria (AMH) is incidentally found during routine health screenings. In the clinical evaluation of persistent AMH imaging modalities, CT urography, MR urography, and retrograde pyelography are of diagnostic importance. In case of pathologic findings (e.

[Percutaneous CT-guided radiofrequency ablation for small renal masses : A retrospective, single center data analysis].

Background: The incidence of small renal masses has increased in recent decades. Standard surgical treatment may not be applicable in patients with advanced age or severe comorbidities. Therefore, minimally invasive therapeutic approaches, such as radiofrequency ablation (RFA), may be a therapeutic option for such patients.

Impact of hours worked by a urologist prior to performing ureteroscopy on its safety and efficacy.

Objective: The aim of this study was to evaluate the impact of hours worked by a urologist before performing ureteroscopy on its safety and efficacy.

Materials And Methods: Patients treated at a single institution from January 2010 to December 2013 were analyzed. The study assessed patient, stone and surgical parameters, stone-free rates and intraoperative complications performed in three work duration categories: less than 6 h, 6-12 h and more than 12 h of urologist's work.
