A study of cervical sagittal parameters change after two modus of anterior cervicalsurgery in cervical myelopathy / 中华骨科杂志

Objective To analyze cervical sagittal parameters change after anterior cervical discectomy fusion (ACDF) and anterior cervical corpectomy fusion (ACCF) in cervical myelopathy.Methods 80 patients with cervical myelopathy who underwent anterior cervical surgery between March 2013 and October 2014 were analyzed in this study.44 patients (24 males,20 females) were operated by ACDF,with an average age of 59.5±4.26 years old and 36 patients (20 males,16 females) were operated by ACCF,with an average age of 62.5±3.85 years old.Japanese Orthopaedic Association (JOA) scores,visual analogue scale (VAS) and neck disability index (NDI) were obtained in all patients preoperatively,6 months after surgery and at the latest follow-up.Standing radiographs of cervical spine,CT (3D) and MR were obtained preoperatively,6 months after surgery and at the latest follow-up.Cervical sagittal parameters were assessed with the following 3 parameters:C2-7 Cobb angle,C2-7 sagittal vertical axis (C2-7 SVA) and T1-Slope.Results All the patients were followed up from 18 to 26 months,with the average time of 22 months.The group of ACDF:JOA scores,VAS scores and NDI scores changed from 8.1±1.4,5.8±1.2,22.2±5.9 to 13.2±1.8,1.5±1.4,10.5± 4.8.The group of ACCF:JOA scores,VAS scores and NDI scores changed from 7.3±1.6,4.9±1.5,24.2±4.3 to 13.9±1.1,1.7±1.2,11.3±4.2.There was no significant difference of JOA scores,VAS scores and NDI scoresbetween two group (t=1.544,0.887,1.666;P=0.134,0.382,0.107).The group of ACDF:C2-7 Cobb angle,C2-7 SVA and T1-Slope angle changed from 17.5°±4.7°,20.3±9.3 mm,35.2°±8.6° to 29.5°±5.2°,11.2±8.6 mm,28.7°±8.2°.The group of ACCF:C2-7 Cobb angle,C2-7 SVA and T1-Slope angle changed from 16.8°±5.1°,19.5±8.6 mm,34.6°±9.1° to 25.3°±4.2°,15.7±9.2 mm,30.3°±7.9°,with significant difference between the two group (t=2.75,2.45,2.34;P=0.039,0.045,0.043).The changes of T1-Slope angle in ACDF group were more significantly (P＜ 0.05).In each group,compared with patients who had low T1-Slope (＜ 25°) preoperatively,the C2-7 SVA in the patients with high T1-Slope (＞25°) was decreased significantly.Compared with patients who had high T1-Slope preoperatively,the C2-7 Cobb in the patients with low T1-Slope was increased significantly.Conclusion Good curative effect could be achieved by ACDF and ACCF in cervical myelopathy.Both surgical methods can maintain the curvature of the cervical alignment and improve the sagittal balance parameters of the cervical alignment.Consideringthe cervical sagittal balance,the ACDF is more suitable for the patient with high T1-Slope angle preoperatively.

Discussion on the operative time of two stage soft ureteroscope lithotripsy for hemorrhagic embolism after percutaneous nephrolithotomy / 中国基层医药

Objective To investigate the the operative time of two stage soft ureteroscope lithotripsy for hemorrhagic embolism after percutaneous nephrolithotomy(PCNL).Methods The clinical data of 1 patient with massive hemorrhage after PCNL who treated with superselective renal artery embolization and ureteral soft lens were analyzed.Results The patient with postoperative bleeding after PCNL was treated with superselective renal artery branch embolization,after 30d embolization,the holmium laser lithotripsy under the soft ureteroscope for ureteral calculi was performed,and the renal pelvis mucosa smooth,no bleeding and scar formation were intraoperative visible.After operation,the stone was removed basically,and the double J tube was removed 2 weeks after operation.The patient had no special discomfort and the renal function was normal.Conclusion Postoperative 14-30d is a relatively safe time to perform flexible ureteroscopic lithotripsy for super selective renal artery embolization in the treatment of patient with massive hemorrhage after PCNL.

Relationship of postoperative systemic inflammatory response syndrome and preoperative midway through the urine and perioperative renal pelvis urine of percutaneous nephrostolithotomy / 中国医师进修杂志

ObjectiveTo explore the relationship of postoperative systemic inflammatory response syndrome(SIRS) and preoperative midway through the urine and perioperative renal pelvis urine of percutaneous nephrostolithotomy(PCNL).Methods Participants included 450 patients with urinary calculus who underwent PCNL,preoperative midway through the urine and perioperative renal pelvis urine of PCNL was collected.ResultsOf 450 cases,preoperative midway through the urine germiculture positive 100 cases (22.2％,100/450 ),perioperative renal pelvis urine germiculture positive 85 cases (18.9％,85/450),46 cases ( 10.2％,46/450) occurred SIRS after PCNL.Decompression of perioperative renal pelvis urine germiculture positive 20 cases(23.5％,20/85) preoperative midway through the urine germiculture positive,perioperative renal pelvis urine the bacteria cultures negative 80 cases (21.9％,80/365 ) preoperative midway through the urine germiculture positive(P ＞0.05),preoperative midway through the urine germiculture positive 15 cases ( 15.0％,15/100) in SIRS,preoperative midway through the urine the bacteria cultures negative 31 cases ( 8.9％,31 /350) in SIRS (P ＞ 0.05 ).Decompression of perioperative renal pelvis urine germiculture positive 18 cases (21.2％,18/85) in SIRS,perioperative renal pelvis urine the bacteria cultures negative 28 cases (7.7％,28/365) in SIRS (P ＜ 0.05 ).ConclusionPreoperative midway through the urine has no correlation with the occurrence of SIRS,perioperative renal pelvis urine germiculture positive can predict the occurrence of SIRS,giving corresponding antibiotic treatment can improve the security of PCNL.

Sonographic Diagnosis and Differential Diagnosis of Acute Testis Diseases / 中国医学影像学杂志

Purpose:It is the authors' intention to improve the diagnostic and differential diagnostic accuracy of ultrasound for acute tes-tis diseases by analyzing the sonographic features.Materials and Methods:The sonographic features of 78 acute testis diseasess were analyzed.The results were compared with the clinical,surgical and pathological results.Results:78 patients had obviously different sonographic features between different types of acute testis diseases.12 testicular tumors were big mass with uneven internal echoes and often with calcification.The distributions of the vessels in the lesions were irregular or branch-like.26 cases of testicular contusion had scrotal wall edema and thickening,with low echo and liquid collection in the lesions.21 cases of acute orchitis usually intumesced with color ball-shaped rich blood flow signals.18 cases with testicular torsion had blood flow on the affected side decreased or disappeared,lcase of tuberculocele showed extremely uneven and various echoes mixed in testis.Conclusion: A fast and exact diagnosis or differential diagnosis of acute testis diseases can be obtained with ultrasound.
