The preservation of the nephrostomy tube after operation brings severe pain to the patients. We use a 1,470 nm semiconductor laser to stop bleeding after the operation, which cannot reserve the nephrostomy tube, fully reflect its safety and effectiveness, and provide a new method for clinical practice.<h4>Methods</h4>Forty-two patients with renal stones who came to our hospital from March 2016 to September 2019 were randomly divided into two groups: laser operation group (20 patients) and traditional operation group (22 patients). The stone removal rate, surgical effect, and postoperative complications were compared between the two groups.<h4>Results</h4>There was no significant difference in the stone clearance rate between the two groups at the 4th week after operation (P>0.05). However, the incidence of postoperative infection, incision pain, and massive bleeding in the laser surgery group were lower than those in the traditional surgery group (P<0.05). However, there was no significant difference in urine extravasation and postoperative hematuria between the two groups (P>0.05). The average postoperative hospital stay in the laser surgery group was shorter than that in the traditional surgery group, and the difference was statistically significant (P<0.05). Simultaneously, there was no significant difference in operation time, intraoperative blood loss, and medical expenses between the two groups (P>0.05).<h4>Conclusions</h4>The 1,470 nm laser is safe, effective, and feasible in PCNL operation, especially in hemostasis of the renal puncture channel, and it is worth popularizing.Translational andrology and urology2172-2178https://www.ebi.ac.uk/biostudies/studies/S-EPMC7658143biostudies-literatureThe clinical research of 1,470 nm laser in percutaneous nephrolithotomy.PMC7658143Hu HWang YTang XfalseThe clinical research of 1,470 nm laser in percutaneous nephrolithotomy.<h4>Background</h4>Percutaneous nephrolithotomy (PCNL) is the primary method for the treatment of renal calculi.
