Abstract:
【Objective】 To evaluate the safety and efficacy of modified ultrasound-guided needle-like visible nephroscope (Needle perc) holmium laser lithotripsy in the treatment of 1-2 cm calyceal calculi, and provide a reference for the selection of clinical treatment methods. 【Methods】 The clinical data of 60 patients with single intrarenal calyceal calculi (the largest diameter 1~2 cm) treated in our hospital during Jan.2022 and May 2023 were retrospectively analyzed.The patients were divided into ureteroscopic holmium laser lithotripsy group (flexible ureteroscope group) and Needle perc group, with 30 patients in either group.The clinical data of the two groups were compared. 【Results】 Compared with the flexible ureteroscope group, the Needle perc group had shorter overall hospitalization time [(3.00±1.25) d vs. (4.00±1.25) d], shorter operation time [(44.63±5.42) min vs. (48.50±7.24) min], lower hospitalization expenses [(15 518±441) yuan vs. (16 872±903) yuan], higher stone-clearance rate [93.3% (28/30) vs. 50.7% (15/30), P<0.001], less increase of procalcitonin after operation [(0.02±0.01) vs. (0.12±0.18), P=0.007], and lower incidence of complications [3.3% (1/30) vs. 26.7% (8/30), P=0.030]. 【Conclusion】 The modified ultrasound-guided Needle perc holmium laser lithotripsy is safe and effective in the treatment of 1-2 cm lower calyceal calculi, with high stone removal rate and low complication rate.
