ABSTRACT
A 77-years-old female patient presented gross hematuria for one week, and CT showed a mass in the left kidney. Ureteroscopy detected a left renal mass. Laparoscopic nephroureterectomy was performed and pathology showed the tumor was mainly located in the renal parenchyma, with glomeruli around the tumor cells. Urothelium showed no obvious dysplasia or clear migration of tumor cells. Considering both the clinical symptoms, and squamous cell carcinoma not detecting in other locations of the patient, primary renal parenchyma was confirmed. Three months after surgery, CT detected recurrence in the operating area, with metastasis to the adjacent abdominal cavity and aorta lymph node.
ABSTRACT
[Objective]To assess the efficacy and safety of low intensity pulsed ultrasonography for fractures.[Methods]According to Cochrane Systematic Review,Medline,EMBASE,Cochrane Library,CNKI and CBM were searched for RCTs,and gray literature were also searched.Furthermore,the bibliographies of retrieved papers and content experts were consulted for additional references.The quality of included studies was critically evaluated.Data analyses were performed with the Cochrane Collaboration's RevMan 5.0 software.[Results]Ten randomized controlled trials with total of 452 patients met the included criteria.The meta-analysis showed treatment with a low-intensity pulsed ultrasound signal can reduce healing time compared with the placebo group(RR=1.43,95% CI[1.15,1.79]P=0.001).[Conclusion]Treatment with a low-intensity pulsed ultrasound signal can reduce healing time.Some trials included in the review were of poor quality.Multi-center,large-scale randomized controlled trials of higher quality are needed to support our results.
