Treatment of ultrasonography guidance percutaneous nephrolithotomy Ⅰ period combining pneumatic ultra-sosonic and holmium laser lithotrips in 120 cases of complex renal calculi / 中国基层医药

ABSTRACT

Objective To assess the clinical efficacy of ultrasonography guidance percutaneous nephrolithot-omyⅠ period combining pneumatic ultrasosonic and holmium laser lithotrips of complex renal calculi.Methods Patients were under the general anesthesia in lithotomy position.By cystoscope first to one side retrograde insertion F5 ureteral catheter,the position to prone position was changed.Under ultrasonography guidance puncture target after the success of the calyx,fascia dilator gradually expanded from F8 to F20 channel was established.Then percutaneous nephroscope combining pneumatic ultrasosonic and holmium laser lithotripsy were administrated.Results One sided single channel was 92 cases,one sided dual channel was 11 cases,one sided three -channel was 1 case.On both sides single channel was 13 cases,one side of the dual channel and other side of the single channel was 3 cases.The operation time was (72 ±24)min.Intraoperative bleeding was in 50 -150mL,with an average of 80mL,and there's no intraoper-ative blood transfusion.2 cases of postoperative had secondary bleeding,in which 1 case remitted after non -operative treatment,the other case was treated in DSA downward super selective renal artery embolization to stop the bleeding. Postoperative hospital stay was 7 -14d,with an average of 10d.There were no septic shock,water uptake,water intoxi-cationand complications such as pleural effusion.One week after the CT,stones free rate was 91.7%(110 /120),in which 10 cases of residual stone with diameter <5mm,needn't surgery removed again.They were treated with oral platoon stone drugs,drinking lots of water and a moderate amount of sports such as processing.All cases were followed up for 6 months to 18 months,with no urinary tract infection,stone recurrence and the long -term complications such as perinephric space effusion.Conclusion As long as establish proper percutaneous renal channel,with intraoperative operating norms,combining pneumatic ultrasosonic and holmium laser,ultrasonography guidance percutaneous nephro-lithotomy Ⅰ period clear renal calculi is completely can be done.And it can shorten operation time,and has clear renal calculi with high efficiency,small trauma and less long -term complications.It is safe and effective,and worthy of clinical popularization and application.
