简要总结
Thulium laser lithotripters allow the urologist to control laser settings
(energy and frequency) to adjust the power that is delivered at the tip of
the laser fibre.
Low energy, high frequency lithotripsy results in tiny fragment sizes that
can pass spontaneously, and this technique has been termed ‘dusting’.
On the other hand, higher energy levels with lower frequencies results
in fragments that require active retrieval with baskets and this
technique has been termed ‘fragmentation’.
The widespread use of thulium laser lithotripsy has created debates
about the best laser lithotripter settings.
A few studies have compared fragmentation and active retrieval with
dusting and spontaneous passage for renal stones, and the laser settings
were not mentioned in one of them.
The present study was conducted to compare two techniques of thulium
laser lithotripsy (dusting and spontaneous passage with fragmentation)
during fURS for renal stones.
