Objective To study the reason and the preventive measures that adverse effects of extracorporeal shockwave lithotripsy (ESWL) for renal stones during treatment.Methods From April 2015 to January 2016,165 patients who underwent ESWL treatment for renal stones were enrolled this retrospective study.All patients were in supine position.Direction of shockwave was by the path of preabdomen.The adverse effects during treatment were observed.The related factors were analyzed by Logistic regression analysis.Results There were 70 cases(42.4％) with pain,10 cases(6.1％) with cold sweat,8 cases (4.8％) with accelerated heart rate,5 cases (3.0％)with descent of heart rate,2 cases (1.2％) with nausea and vomiting.In the univariate Logistic regression analysis,four variables (BMI,history of ESWL treatment,stone location and energy) were found showing statistical significance.Multivariate Logistic regression analysis showed that the final significant related factors were BMI ＜ 24.0 kg/m2 (OR =4.155,CI 1.373-12.571),history of ESWL treatment (OR =0.163,CI 0.058-0.454),stone in pelvis(OR =123.051,CI 17.638-858.439),stone in middle calyceal (OR =169.171,CI 29.677-964.343),energy 86.3-94.7J (OR =0.094,CI 0.025-0.362).Conclusions Pain was the most common adverse effect during the treatment of ESWL.Stone location (pelvis and middle calyceal) was an independent risk factor,BMI ＜ 24.0 kg/m2 was one of the related risk factors.Both energy 86.3-94.7J and history of ESWL treatment were preventive factors.

Objective To evaluate the effect of one step flexible ureteroscopic lithotripsy for incarcerated upper ureteral calculi.Methods The clinical data of 80 cases of incarcerated upper ureteral calculi were retrospectively analyzed between August 2015 and September 2016.Theone step flexible ureteroscopic lithotripsy was used in 40 cases (one step group),including 22 male cases and 18 female cases.The average age was (40.0 ± 9.5) years.The maximal stone diameter was (i.8 ± 0.5) cm.The widest width of the ureter above the stone was (2.5 ± 1.1) cm.The CT value of stone was (1 089.0 ± 111.3) HU.Two step method was used in 40 cases (two step group),including 21 male cases and 19 female cases.The average age was (41.0 ± 10.7).The maximal stone diameter was (1.7 ± 0.6)cm.The widest width of the ureter above the stone was (2.3 ± 0.9) cm.The CT value of stone was (1 002.0 ± 97.2) HU.During the one step flexible ureteroscopic lithotripsy,only flexible ureteroscope was used to crush the stone,no matter whether the stone located in the ureter or return to the renal pelvis.During two stepmethod,the rigid ureteroscopy was firstly used for crushing the stone in the ureter.When the stone return to the renal pelvis,the rigid ureteroscopy was change into flexible ureteroscope for continuous crushing the stone.Compared two groups' operating time,2 weeks stone clearance rate and the cases of fever after operation.Results The mean operative time in the one step group was (37.45 ± 11.34) min.The mean operative time in the two step group was (55.07 ± 13.57) min.The difference was statistically significant (P ＜ 0.05).The number of infection 2 cases in one step group and 9 cases in two step group.The difference was statistically significant (P ＜ 0.05).2 weeks stone clearance rate was 87.5％ (35/40) in one step group and 82.5％ (33/40)in two step group.There was no significant difference between two groups.Conclusions Flexible ureteroscope one step method is a safe and effective alternation for incarcerated upper ureteral calculi.

Objective To systematically evaluate the optimal indwelling time of double?J stent in the treatment of ureteral complicated calculi post?ureteroscopy. Methods A total of 161 patients with complicated ureteral calculi were enrolled in this study from August 2012 to August 2015. All patients received the treatment of ureteroscopic holmium YAG Laser lithotripsy and were randomly divided into 3 groups according to varied double?J stent indwelling time: group A < 2 weeks (n = 43),group B from 2 ~ 6 weeks(n = 67),and group C>6 weeks (n = 51). Complications of three groups were compared and the hydronephrosis after removing double?J stent was recorded. Results The rate of complications of group C was significantly higher than that in group A and group B (P<0.017). However,group A(10/43)has a higher rate of ureterostenosis after removing double?J stent compared with group B(4/67)and group C(3/51),while no statistical significance was observed between group B and group C. Conclusion The incidence of complications after lithotripsy increased with the indwelling time of double?J stent,but the short indwelling time would led to ureterostenosis. Therefore,the optimal indwelling time of double?J stent after flexible ureteroscopy was 2 to 6 weeks,and the indwelling time for patients with injury ureteral mucosa could be appropriately prolonged.

Objective To evaluate the effects of posterior segmental pedicle screw instrumentation and augmentation using calcium sulphate cement in treatment of Denis type B thoracolumbar burst fractures.Methods Forty patients with Denis type B thoracolumbar burst fracture treated between January 2011 and December 2012 were reviewed retrospectively.Twenty patients received posterior short-segment pedicle screw fixation in conjunction with screw placement at the level of fracture and calcium sulphate augmentation without posterolateral fusion (combined treatment group),but 20 patients underwent traditional short-segment pedicle screw fixation (conventional treatment group).Radiographs and CT scans evaluated local kyphotic angle on the spot of injury,anterior height of the injured vertebra,and canal encroachment before and after operation and at final follow-up.Meanwhile,visual analogue score (VAS),Oswestry disability index (ODI),and neurologic status based upon ASIA 2000 were assessed.Results Mean follow-up period was 15 months (range,12-24 months).Vertebral height restoration was equivalent of the two groups immediately after operation,but better result of kyphosis correction was found in treatment group than in control group (P ＜ 0.05).Anterior vertebral height and kyphotic angle significantly improved in treatment group compared to control group at final follow-up (P ＜ 0.05).Clinical and neurologic outcome evaluation were similar between the two groups.No implant failure occurred at follow-up.Conclusion For Denis type B thoracolumbar burst fractures,posterior segmental pedicle screw fixation augmented with calcium sulphate is effective for reducing correction loss and implant failure,compensating for the deficiencies of conventional fixation.

Methods The data of 358 patients were analyzed,with 204 male and 154 female and with 276 cases of solitary stones and 82 cases of multiple stones.Determine the composition of kidney stones by shap and density,predict the efficacy of ESWL by X-rays,and choose the appropriate method of treatment.Analyze stone chemical property by Infrared stone composition automatic analyzer to checkout the prediction results before surgeries. Results 339 cases were successful to remove stones after treatment.The prediction results of 308 cases (86.0％) were consistent in stone chemical property,and the preperative prediction results of 339 cases (94.7％) were consistent in ESWL efficacy. Conclusions Determination of composition of kidney stones and prediction of the efficacy of ESWL by X-rays were feasible.

Objective To evaluate the clinical efficacy of treatment of severe thoracolumbar burst fractures by posterior short-segment instrumentation without spinal fusion and assess radiographic imaging and function recovery after surgery.Methods Thirty-eight patients with severe monosegmental thoracolumbar burst fractures treated between July 2011 and March 2013 were analyzed retrospectively.Operation procedures were posterior short-segment pedicle screw distraction reduction and fixation combined with screw insertion to the injured vertebrae and calcium sulphate augmentation.In addition,there was no need for posterolateral interbody fusion.X-ray and CT were performed before and after operation to evaluate local kyphotic angle,anterior fractured vertebral body height and canal encroachment.Visual analogue scale (VAS) and Oswestry disability index (ODI) were assessed before and after operation as well as in follow-up.Results All patients were followed up for average 14 months (range,3-20 months).Local kyphotic angle was (21.2 ±4.3)° before operation,(3.5 ± 1.8)°immediately after operation,and (4.8 ± 2.7) ° in final follow-up.Relative anterior vertebral height was (54.8 ± 14.6)％ before operation,(91.7 ± 8.0)％ after operation,and (87.2 ± 6.0)％ in final follow-up.Mean canal encroachment was (48.0 ± 4.5)％ preoperatively,(23.8 ± 7.8)％postoperatively,and (8.8 ± 4.6) ％ in final follow-up.In final follow-up,six patients with American Spinal Injury Association (ASIA) grade C on admission showed improvement to grade D (n =2) and grade E (n =4) ; 10 patients with ASIA grade E on admission showed improvement to grade E; 22 patients with grade E had no changes.ODI and VAS scored 15.5 ±8.8 and 2.3 ±0.8 in final follow-up with substantial improvement from those before operation (P ＜ 0.01).Complications from internal fixation were not found during follow-up.Conclusion Posterior short-segment fixation without fusion is one of the foremost effective methods for severe thoracolumbar burst fractures,for it can effectively restore the sagittal spinal alignment and the fractured vertebral body height.

Objective To observe the curative effect of external physical vibration lithecbole (EPVL) therapy after extracorporeal shock-wave lithotripsy (ESWL) in upper urinary calculi.Methods A total of 133 patients of upper urinary calculi with randomly divided into 2 groups after ESWL therapy during the period of 2012 October to 2013 February.The EPVL group (66 cases) used the physical vibration lithecbole treatment,and the natural lithecbole group (67 cases) used the method by drinking water,adding exercise and other natural lithecbole method.Of the EPVL group,6 of the stones were located in the upper or middle calyx,13 in renal pelvis,16 in lower renal calyx and 31 in ureter,the stone diameter was 10-15 mm.Of the natural lithecbole group,8 of the stones were located in the upper or middle calyx,17 in renal pelvis,15 in lower renal calyx and 27 in ureter,the stone diameter was 10-15 mm.The clinical data of the curative effect,side-effect,and complications were collected and analyzed systematically.Results In the EPVL group,the average times of lithagogue treatment was 2.6 times,51 patients (77％) expelled stones on the day of lithecbole,and the stone free rate in a week was 79％ (52/66).Especially,81％ (13/16) of the lower renal calyx expelled stones on the day of lithecbole,and the stone free rate in a week was 88％ (14/16).Whereas,30 patients (45％) in the natural lithecbole group expelled stones on the day of ESWL,and the stone free rate in a week was 49％ (33/67) ; the lower renal calyx stone expulsion rate on the day of ESWL was 33％ (5/15),and the stone free rate in a week was 40％ (6/15).The curative effects were significantly different between the 2 groups (P＜ 0.05).There were no serious complications in both groups.Conclusions EPVL machine can significantly promote the stone expulsion after ESWL.Compared with traditional methods,EPVL therapy has a better curative effect,especially on lower renal calyx stones.EPVL is a safe and noninvasive treatment.

Vagus nerve reflex is a rare complication of percutaneous renal decompression. It is often induced by excessively rapid decompression of severe hydronephrosis and traction of the main nerves innervating the kidney. The clinical manifestations are irritability, sweating, clammy skin, hiccups, slow heart rate. It is easy to misdiagnose. In this study, 4 patients with vagus nerve excitement after percutaneous renal decompression were treated. After monitoring the patient’s vital signs and giving treatment such as expanding blood volume and raising blood pressure, the symptoms gradually disappeared.
