Mini & Micro Percutaneous
For treatment of kidney stones
About Mini-Perc, Ultra-Mini-Perc & Micro-Perc
For kidney stones of less than 2 cm size, percutaneous nephrolithotomy can be perfomed via smaller endoscopic accesses compared to standard PNL.
The size of mini-nephroscopes is in the range of 15-18 Fr with a 5-7 Fr. working channel, allowing to use either the Swiss LithoClast® Master 1.9 mm ultrasonic probe for efficient fragmentation of stones and simultaneous removal or the Swiss LithoClast® pneumatic probe for effective fragmentation and separate fragment removal.
The ultra-mini-perc (UMP) endoscope has an operating sheath size of 11-13 Fr. and a 3 Fr. working channel. Most commonly, a holmium laser like the Swiss LaserClast® is used with the UMP endoscope. The micro-perc endoscope has a sheath size of 9-10 Fr. and is used with Holmium lasers like the Swiss LaserClast® through a 3 Fr. working channel.
