Abstract
Mini-PCNL (16 CH) with the use of "Bernoulli" or "vacuum cleaner" effect for irrigation of fragments from the upper tract seems to be an excellent choice of treatment. It is fast, effective and it does not require use of any expensive extraction devices.
We would like to present our experience with mini-PCNL using Karl Storz MIP instruments. The advantage of this method is small diameter access, minimal blood loss and single step dilatation, without traumatisation of the upper urinary tract.
The fragmentation is easily performed by standard Ho:YAG laser.
