ABSTRACT

Objective To observe the clinical efficacy of percutaneous nephrolithotomy ( PCNL ) with Holmium laser and no help of irrigating pump in the treatment of renal calculi in 127 cases.Methods From January 2012 to November 2017 ,a total of 127 patients with renal calculi have suffered mini -PCNL with Holmium laser and no help of irrigating pump by using 16F or 18F Urovision percutaneous nephrostomy kit in Peking University Shougang Hospital ,the Hospital of Mentougou District and the Traditional Chinese Medicine Hospital of Mentougou District were collected.The operation time, intraoperative blood loss, hospitalization stay, lithotripsy rate, stone clearance and principal complications of operation were analyzed statistically .Results The first phase success rate of percutaneous nephrostomy was 100％, lithotripsy rate was 24.4％, stone clearance rate was 24.4％.The operation time was (36.1 ±15.6)min.The intraoperative blood loss was (45.4 ±31.7)mL.But postoperative abdominal X-ray showed that 96 patients with residual calculi ≥ 4mm needed to receive the second look PCNL .These 96 patients reached 100.0％ of lithotripsy rate and 100.0％ of stone clearance postoperatively .The operation time was ( 64.5 ± 31.1)min.The intraoperative blood loss was (23.1 ±21.9)mL.No severe complications such as massive hemorrhage occurred.The hospitalization stay was (12 ±5 ) d.Conclusion Larger renal calculus except complete staghorn calculus,and upper ureteral calculus are the indications for PCNL with Holmium laser and no help of irrigating pump . It is safe and feasible to perform PCNL with Holmium laser and no help of irrigating pump .
