1 Objective To explore the effect of intrasinusal pyelolithotomy plus postrenal low pole segmentalincision for removal of calculus for the treatment of complex renal calculi.

2 Conclusion The combination of pyelolithotomy and ballast lithotripsy is a fairly effective approach to treat staghorn calculi.

3 Objective To evaluate the effects of intrasinusal pyelolithotomy for the removal staghorn stone.

4 Objective To compare the effect of nephrolithotomy with pyelolithotomy plus ballast lithotripsy anatrophic renal staghorn calculi.

5 Objective To compare the effect of nephrolithotomy with pyelolithotomy plus ballast lithotripsy for anatrophic renal staghorn calculi.

6 The utility model relates to a mushroom-shaped pyelolithotomy stoma skin patch, which belongs to the field of medical appliances.

7 To evaluate intrasinusal pyelolithotomy with ballast lithotripsy in the treatment of staghorn calculi, the procedure was carried out in 27 cases.

8 Objective To explore the effects of pyelolithotomy and ballast lithotripsy in the treatment of staghorn calculi.

9 Method 160 cases were randomized into group A and group B, with 80 cases for each. Pyelolithotomy plus ballast lithotripsy were performed in group A and nephrolithotomy in group B.

10 Methods In a total of 626 patients, 606 were treated with percutaneous nephrolithotomy (PCN-L) and 20 with modified incision of renal calices and pyelolithotomy.

11 Methods 78 patients with giant staghorn calculi were treated by incision of renal posterior lip and pyelolithotomy.

12 Objective To evaluate the application of flexible renoscope to pyelolithotomy . Methods The flexible renoscope has been applied to multiple nephrolithotomy through pelvis.

13 Methods Clinical data of 41 cases with renal giant staghorn calculi treated with incision of the renal posterior lip pyelolithotomy were retrospectively analyzed.

14 Methods The data of 38 cases treated with intrasinusal pyelolithotomy and nephrolithotomy were analysed.

15 Methods: The data of 68 cases treated with intrasinusal pyelolithotomy were analysed.

16 Methods The staghorn calculi of 46 patients were fragmented into several pieces with pyelolithotomy and ballast lithotripsy and were then taken out one by one.
