Percutaneous nephrolithotomy(PCNL)is important in the treatment of upper urinary tract stones,and tubeless day-time surgery is a promising approach.It can improve the patients'hospitalization experience and shorten hospitalization time,but it also faces risks such as difficulty in managing residual stones after surgery,urinary extravasation caused by poor ureteral drainage,and so on.Currently,there are insufficient guiding principles in this regard.Based on our experience and relevant literature,this paper will discuss the technical points of day-time tubeless PCNL and explore its feasibility.
