Objective To study the efficacy and safety of controlled negative pressure suction sheathing combined with flexible ureteroscopic holmium laser lithotripsy in the treatment of kidney stones <3cm. Methods Patients with kidney stones diagnosed in Tinghu District Peoples Hospital during 3 years from December 2019 to December 2023, with the largest diameter <3cm, were selected and divided into observation group and control group according to treatment methods. Observation group 57 patients, controlled negative pressure suction sheath combined with flexible ureteroscopic holmium laser lithotripsy lithotripsy. In control group, 54 patients were treated with flexible ureteroscopic holmium laser lithotripsy alone. The data of immediate stone removal rate, lithotripsy time and postoperative complications between the two groups were analyzed and compared. Results The average operation time, lithotriptic time and indentation time of double J tube in observation group were significantly lower than those in control group, with statistical difference (P < 0.05). There was no significant difference between observation group and control group in immediate stone removal rate and hospital stay (P > 0.05). The incidence of postoperative infection in the observation group was lower than that in the control group, with statistical difference (P < 0.05). Patients in both groups were followed up for 3 months after surgery, and no significant stone residue was found in the review. Conclusion Controlled negative pressure suction sheath combined with flexible ureteroscopy for the treatment of kidney stones <3cm has the advantages of short postoperative catheterization time, short operation time and low complications, and is safe and efficient.
