ABSTRACT
Objective To explore the application of visible standard channel combined with F4.8 visible puncture percutaneous nephrolithotomy in the treatment of multiple renal calculi. Methods The clinical data of 46 patients with multiple renal calculi from October 2015 to September 2016 were retrospectively analyzed. There were 28 male and 18 female, with a mean age of 42.6 years (aged from 25 to 65 years). Stone diameter 3.0~5.2 cm, average (4.3 ± 0.8) cm. Application of F4.8 visual puncture assisted angioplasty to establish the standard channel, nephrolithotomy combined with ultrasonic lithotripsy treatment in the field of visible stones, then apply the F4.8 visual micro puncture percutaneous nephrolithotomy combined with holmium laser treatment of other parts of the stone, summarizes the channel establishment total time, operation time, blood red protein decreased and stone clearance rate and complication index. Results All cases were successfully established single standard channel under the guidance of F4.8 visual puncture, 24 cases were combined with single ultramicro channel, 16 cases were combined with double ultramicro channels, and the other 6 cases were combined with the three ultra micro channels. Postoperative indwelling single renal fistula, micro channel indwelling fistula, postoperative indwelling F5 double J tube. F4.8 visual puncture established standard channel establishment time (6.8 ± 1.8) min, single F4.8 visible puncture ultra - channel establishment time of (4.5 ± 0.9) min, operation time of (92.0 ± 15.0) min. A stone clearance rate was 91.3% (42/46), a decrease in hemoglobin value of (12.2 ± 2.5) g/L, 8 cases of postoperative fever, given anti-inflammatory treatment improved, 4 cases with residual calyceal stones visible 0.5~0.8 cm, given extracorporeal shock wave lithotripsy combined with postural drainage, stone, 1 months after the treatment of stones were discharged, did not appear Shi Jie, delayed bleeding, adjacent organ injury, ureteral injury cases. Conclusion Visual standard channel combined with F4.8 ultra visible puncture percutaneous nephrolithotomy in treatment of multiple renal calculi has the advantages of reducing the large number of channels, high stone clearance rate, safety, less complications, F4.8 was used to establish the visual puncture channel is more safe and accurate.

ABSTRACT
Objective To evaluate the efficacy, advantages and shortcomings of micro-percutaneous nephrolithotomy in treatment of uncomplicated ureteral calculi.Methods Clinical data were collected from 126 patients with a failure treatment of history by ESWL (extracorporeal shock wave lithotripsy) and RIRS (retrograde intrarenal surgery) in treatment of upper ureteral calculi (< 3.0 cm) from June 2015 to May 2016. Antegrade percutaneous access was obtained by B-type ultrasound guidance. Micro-PCNL was done using YAG laser fiber or pneumatic through the ureteroscope (F4.5~F6.5、F6.0~F7.5, 315 mm) to disintegrate the stones. The calculi clearance rate, operation time, operative hemorrhage, length of hospital stay and complications of the patients were analyzed after operation.ResultsThe calculi clearance rate was 88.9%, the operation time was 15~75 min, the operative hemorrhage was 15~35 ml, the length of hospital stay was 5~10 d. Only one patient need the second stage surgery because of intraoperative hemorrhage affected the surgical ifeld. No patients occurred massive hemorrhage, pneumothorax, bowel and other complications such as organ damage.Conclusion Micro-PCNL had a good clinical curative effect and security in treatment of uncomplicated ureteral calculi, which was worthy of promoting clinically.
