BACKGROUND Upper urinary tract stones are very common in my country,with an incidence of 1%to 5%in the North and an even higher incidence of 5%to 10%in the south.The incidence rate in the south is higher than that in the north,mainly due to the water quality,climate and eating habits of the region.From the perspective of sex,incidence is more likely in males than females.In the high-incidence population,young adults are most prone to stones.Men in the age range of 25 to 40 years are more likely to have stones.AIM To observe the therapeutic effect of minimally invasive percutaneous nephrolithotomy(mPCNL)on upper urinary tract stones and its influence on the renal function of patients.METHODS Patients with upper urinary tract stones who were treated in our hospital from February 2017 to March 2018 were selected as research subjects and were divided into the PCNL group and the mPCNL group according to the random number table method.The general conditions of the two groups of patients were observed during the perioperative period,and the differences in stone clearance,pain,renal function indicators and complication rates were compared between the two groups to determine which were statistically significant(P<0.05).RESULTS The operation time of the mPCNL group was longer than that of the PCNL group(t=-34.392,P<0.001),and the intraoperative blood loss of the mPCNL group was more than that of the PCNL group(t=34.090,P<0.001).There was no difference in renal function indices between the two groups of patients before treatment,and there was no difference in the levels of serum creatinine,β2 microglobulin or retinol binding protein in the mPCNL group after treatment.The visual analog scale score of patients in the mPCNL group was lower than that of the PCNL group(t=12.191,P<0.001),and there was no significant difference in the stone clearance rate between the two groups(χ2 value=1.013,P=0.314).There was no significant difference in the incidence of urine extravasation,dyspnea and peripheral organ damage between the two groups(χ2 value=1.053,P=0.305).At 1 mo after treatment and 3 mo after treatment,the quality of life of the mPCNL group was lower than that of the PCNL group,and the Qmax level of the mPCNL group was higher than that of the PCNL group.CONCLUSION mPCNL has a good therapeutic effect on upper urinary tract stones,with a high stone clearance rate without causing kidney damage or increasing the incidence of complications,and thus has good application value. 展开更多

Objective: To retrospectively evaluate appropriate treatment for patients with symptomatic caliceal diverticular calculi, by comparing the therapeutic outcomes for those undergoing minimally invasive percutaneous nephrolithotomy (MPCNL) and flexible ureterorenoscopy (F-URS). Methods: From March 2009 to May 2014, 36 consecutive patients with caliceal diverticular calculi were divided into 2 groups:21 patients underwent MPCNL, and 15 were treated by F-URS. All procedures were performed by one surgical group, which ensured relatively constant parameters. Patient characteristics, operative time, hospital stay after surgery, stone-free rate, symptomatic improvement rate, complications, diverticular obliteration, and stone composition were analyzed retrospectively in the 2 groups. Results: Patient preoperative variables were comparable between the two groups, with no significant difference (P>0.05). Mean operative time was 136.9 ± 22.8 min in the MPCNL group and 117.3 ± 24.3 min in the F-URS group (P ? 0.019). Hospital stay was significantly longer in the MPCNL group than in the F-URS group (9.4 ± 3.1 vs. 6.9 ± 2.1 days, P ? 0.010). The stone-free rates after MPCNL and F-URS were 90.5%(19/21) and 60.0%(9/15), respectively (P ? 0.046). Additionally, 71.4%(15/21) of patients in the MPCNL group and 46.7%(7/15) of patients in the F-URS group had symptomatic improvement at the 6-month follow-up (P ? 0.175);the rates of complications in the 2 groups were 19.0%(4/21) and 13.3%(2/15), respectively (P ? 0.650). Complete diverticular obliteration was achieved in 16 (76.2%) cases in the MPCNL group and 5 (33.3%) cases in the F-URS group (P ? 0.017). The distributions of calcium oxalate and hydroxyapatite in the stones were 66.7% (14/21) and 33.3% (7/21), respectively, in the MPCNL group;however, the distributions in the F-URS group were 46.7%(7/15) and 53.3%(8/15), respec-tively (P ? 0.310). Conclusion: MPCNL is an effective method for the treatment of caliceal diverticular calculi. However, F-URS is an alternative technique in selected patients with a patent infundibulum, despite lower stone-free rates than with MPCNL. Fulguration of the diverticular lining with a high-power holmium laser and permitting the cavity to collapse are useful to increase the chance of diverticular obliteration. 展开更多

Objective:To evaluate whether there would be a difference in outcome when the smaller ultra-mini 12 Fr sheath was used instead of the mini 16 Fr sheath for percutaneous nephrolithotomy(PCNL)in paediatric patients for stones less than 25 mm.Methods:This was a prospective cohort study of patients who underwent PCNL in our hospital in a 2-year period from July 2016 to June 2018 by a single surgeon.PCNL was performed in a prone position and tract was dilated to the respective size using single step dilatation.Laser was used to fragment the stone.Stone-free outcome was defined as absence of stone fragment at 3 months on kidney,ureter,and bladder X-ray.Results:There were 40 patients in each group.Mean stone size was comparable between the two groups(14.5 mm vs.15.0 mm).The procedure was completed faster in the 16 Fr group compared to 12 Fr group(24.5 min vs.34.6 min).Stone clearance was highly successful in both groups(97.5%vs.95.0%).There was no difference in complications between the two groups.The decrease in hemoglobin was minimal in both groups(0.2 g/dL vs.0.3 g/dL).Conclusion:We found that the success rates were similar in both mini PCNL and the smaller ultra-mini PCNL groups.No significant difference in bleeding was noted in our pilot study,however,operative time was longer in the ultra-mini group as compared to the mini sheath group. 展开更多
