In recent years, the incidence of kidney stones in children is on the rise, and the prevention and treatment of children's kidney stones has gradually become a concern of urology. With the continuous innovation of medical devices and the perfect combination with clinical medicine, a new surgical method - needle nephrolithotripsy (Needle-perc®) emerged as the times require, bringing good news to children with upper urinary tract stones.

       Needle-perc®, the smallest diameter of the needle is 4.2F, and the working channel is 3.6F. It is the thinnest visible nephroscope at present. It has the advantages of simple operation, less trauma, less bleeding, high efficiency and quick recovery. , fewer complications and so on. For children with kidney stones, because of their soft texture and high requirements for kidney protection, needle-shaped nephroscope (Needle-perc®) lithotripsy is used without the need to expand the channel, and only small needle holes can be seen on the skin after surgery, and no indwelling is required after powdered crushed stones The fistula can greatly reduce kidney damage and relieve postoperative pain in children.

Professor Liu Dong from Xinjiang Children's Hospital performed Needle-perc® lithotripsy on a 2-year-old child with complicated kidney stones

Professor Zhong Liang from Shanghai Children's Medical Center Affiliated to Shanghai Jiaotong University School of Medicine performed Needle-perc® lithotripsy on a 3-year-old child

Professor Dorje Tashi from Lhasa People's Hospital performed Needle-perc® lithotripsy on a 1-year-old Tibetan child

           The preoperative evaluation, surgical indications, and operation of PNL in children are similar to those of adults, and the complication rate is about 20%. Compared with adults, children have smaller kidney volume, stone load, and collecting system space, and are more suitable for small channel PNL. ; Needle nephroscope is used to deal with children's 10-20mm kidney stones, the SFR is similar to mini-PNL and less traumatic. In addition, with the reduced operating channel, tubeless is more feasible, which helps to shorten the hospital stay and control postoperative pain.
