A nephrolithometric nomogram to predict treatment success of percutaneous nephrolithotomy.

Purpose: Imaging is routinely done preoperatively and postoperatively to assess patients treated with percutaneous nephrolithotomy. We developed a nomogram for percutaneous nephrolithotomy success.

Materials And Methods: From November 2007 to December 2009 the CROES (Clinical Research Office of the Endourological Society) collected data on consecutive patients at 96 centers globally.

Does imaging modality used for percutaneous renal access make a difference? A matched case analysis.

Objective: To assess perioperative outcomes of percutaneous nephrolithotomy (PCNL) using ultrasound or fluoroscopic guidance for percutaneous access.

Methods: A prospectively collected international Clinical Research Office of the Endourological Society (CROES) database containing 5806 patients treated with PCNL was used for the study. Patients were divided into two groups based on the methods of percutaneous access: ultrasound versus fluoroscopy.

Categorisation of complications and validation of the Clavien score for percutaneous nephrolithotomy.

Background: Although widely used, the validity and reliability of the Clavien classification of postoperative complications have not been tested in urologic procedures, such as percutaneous nephrolithotomy (PCNL).

Objective: To validate the Clavien score and categorise complications of PCNL.

Design, Setting, And Participants: Data for 528 patients with complications after PCNL were used to create a set of 70 unique complication-management combinations.
