The ideal puncture approach for PCNL: Fluoroscopy, ultrasound or endoscopy?

Supracostal Puncture in PCNL: Our Experience

Percutaneous nephrolithotomy has become the cornerstone and one of several procedures developed over the past decades. The planning, patient selection and an effective perioperative protocol are crucial for the outcome of PCNL. Although many standardized techniques established for the management of renal and upper ureteric calculus, supracostal approach is widely used and accepted. The objectiv...

The oblique interlaminar approach for fluoroscopy-guided lumbar puncture: keep the eye opened!

Ultrasound versus Fluoroscopy Guided Percutaneous Nephrolithotomy for Treatment of Calculi in Hydronephrotic Kidneys

Purpose: To compare the success and complication rates of ultrasound with fluoroscopically guided Percutaneous Nephrolithotomy (PCNL) in hydronephrotic kidneys. Patients and Methods: The computer archived files of patients with renal calculi who underwent PCNL between October 2007 and November 2012 were retrospectively reviewed. The study included adult patients with hydronephrotic kidneys. Bas...

Ultrasound for routine lumbar puncture.

OBJECTIVES The objective was to determine if use of ultrasound (US) by emergency physicians (EPs) to localize spinal landmarks improves the performance of lumbar puncture (LP). METHODS This was a prospective, randomized, controlled study conducted in a county teaching hospital. Subjects, adults 18 years of age or older who were to receive LPs for routine clinical care in the emergency departm...

Registration between ultrasound and fluoroscopy or CT in prostate brachytherapy.

PURPOSE In prostate brachytherapy, transrectal ultrasound (TRUS) is used to visualize the anatomy, while implanted seeds can be visualized by fluoroscopy. Intraoperative dosimetry optimization is possible using a combination of TRUS and fluoroscopy, but requires localization of the fluoroscopy-derived seed cloud, relative to the anatomy as seen on TRUS. The authors propose to develop a method o...
