Abstract: Objective To investigate the nursing approaches with standard-PCNL auxiliary combined with mini-PCNL in treating complicated calculi. Methods Retrospective analysis were used in 56 cases with complex calculi in our hospital from 2010 July to 2012 July treated with standard-PCNL assisted with mini-PCNL. Results Of the 56 patients , all were successfully established standard tract and mini tract and one stage procure were take on all cases , 51 cases were completely removed the stone, the stone free rate(SFR) was 91%, 5 cases of residual calculi which extracorporeal shock wave lithotripsy (ESWL) were used in 5 cases. Operative time were 40~100 min, with a average of 78 min. Intraoperative blood loss was 50~200 mL, average 130 mL. The hospital staying time were 5~10 d, the average hospitalization time was 7 d. Postoperative bleeding, infection, double J cather shifting complications recovered after conservative treatment. All patients were followed up for 3~18 months, the results indicated that there was no delayed hemorrhage, severe infection. Conclusion Our results show that there are many advantages of applying standard-PCNL combined with mini-PCNL in treating complicated calculi, with a high SFR, short operation time, less bleeding. Carefully nursing care is important to approval the success rate of operation and rehabilitation of patients.
