In vitro assessment of a novel spearheaded pneumatic intracorporeal lithotriptor.

Background And Purpose: Intracorporeal lithotripsy is an important modality used for stone pulverization. To improve the pulverization properties of intracorporeal lithotriptors, a novel intracorporeal "spearheaded lithotriptor" was designed by our institute. It was compared in vitro with the conventional lithotriptor.

A novel 5-part Percutaneous Access Needle with Glidewire technique (5-PANG) for percutaneous nephrolithotomy: our initial experience.

Objectives: To describe the use of an innovative 5-part Percutaneous Access Needle with Glidewire (5-PANG), a novel technique in an attempt to make percutaneous nephrolithotomy (PCNL-a routinely performed procedure) tract establishment a fast, safe, and less cumbersome procedure.

Methods: An access needle (5-PANG needle) was designed and fabricated at the Institute of Urology, Dhule, and used for percutaneous renal access during PCNL.

Results: The 5-PANG technique was used in 55 cases (57 renal units).
