Minimally invasive adnexa-sparing surgery for benign ovarian and paratubal masses in children.

Background: The precision of minimally invasive surgery (MIS) to resect benign ovarian and paratubal masses while preserving adnexa in children is unclear. This study evaluated the integrity of laparoscopy to spare adnexa while resecting benign pathologies in children.

Methods: The institutional pathology database was queried to identify patients aged 18 years and younger having any ovarian or tubal lesion resected at a comprehensive children's hospital between 2006 and 2021.

Combined Burst Wave Lithotripsy and Ultrasonic Propulsion for Improved Urinary Stone Fragmentation.

Purpose: Burst wave lithotripsy (BWL) is a new technology in development to fragment urinary stones. Ultrasonic propulsion (UP) is a separate technology under investigation for displacing stones. We measure the effect of propulsion pulses on stone fragmentation from BWL.
