ABSTRACT
Objective To summarize the experience of partial tubeless mPCNL. Methods A retrospective analysis of partial tubeless mPCNL surgery experience from January 2010 to December 2016. Atotal of 1320 patients underwent mPCNL surgery in these 7 years.Out fo those 1320 patients,554 patients underwent partial tubeless mPCNL,766 patients underwent standard mPCNL,and 85 exception cases of standard mPCNL were forced to abort surgery due to maximum surgery time of 2 hours and different complications such as bleeding, infections and etc, so total of 681 patients with standard mPCNL were compared with partial tubeless mPCNL.Results The rate of partialtubeless mPCNL has increased by 84% in 2016, with an indication of tubeless mPCNL being extended, while the complication rate showed no increase. Compared with the standard mPCNL, there was no significant dif-ference between the two groups in the rate of stone removal, drop in mean hemoglobin, blood transfusion and postoperative fever. There were significant differences in postoperative analgesic use rate (5%:21%,P=0.001) and hospitalization stay (2.5:4.5d,P=0.001) . The rate of postoperative bleeding complications in partial tubeless group and standard group is 1.1%and 2.5%respectively, but difference is not statistically significant. There were 1cases of urinary extravasations in the partial tubeless group which was treated by perirenal drainage, antibiotic treatment, and 1 cases of pleural injury, which were treated by open exploration, and chest tube placement. Conclusion In compared to standard mPCNL partial tubeless mPCNL significantly increased patients postoperative comfort, shorten hospital stay,and no complications increased.Partial tubless mPCNL is a safe and practicable procedure.
