In this rich series of patients with ambulatory PCNL, stone free rate in non-staghorn lithiasis was 91%. The methods used by the authors was combining flexible nephoscopy and post-operative ultrasound, which allowed us to trust in the results obtained. Ultrasounds can be confusing when less than 5 millimeter stones are found, but precision when no stones are found it is nearly 95%. There is evidence about the safety of a tubeless approach (without nephrostomy tube NT). Based on their own results, the authors avoided a NT in almost 80% of patients. Tubeless procedures (without JJ) were used in 20% of the patients and will surely become the standard procedure in non -complicated cases. Stent syndrome produces a strong impairment in quality of life. Combining mini perc (less bleeding) with flexible nephoscopy (higher stone free rate) allows us to perform more tubeless procedures and in selected cases, a totally tubeless approach.
