A novel less-traumatic needle for kidney puncture: first clinical experience.

Introduction: To decrease complication rate, we developed a novel MG needle for kidney puncture consisting of a pointed cannula, an atraumatic mandrin-bulb and a spring mechanism pushing the mandrin-bulb forward.

Aim Of The Study: To assess efficacy and safety of kidney puncture during percutaneous nephrolithotomy (PCNL) using a novel less-traumatic MG needle within a clinical trial.

Materials And Methods: We conducted a prospective randomized single-center study.

A Novel and Less Traumatic Needle for Kidney Puncture: Development and Preclinical Study Results.

A considerable proportion of percutaneous nephrolithotomy complications occurs during renal puncture. An option to decrease the complications rate is needle modification to make the procedure less traumatic. We aimed to evaluate the effectiveness of the novel MG needle in a preclinical study.
