ABSTRACT
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.
ABSTRACT
Objective To investigate the associations between the single nucleotide polymorphisms of TERT rs2736098, CLK3 rs11543198 and bladder cancer. Methods 201 bladder cancer cases and 200 healthy controls were included in the research, and the genotypes of TERT rs2736098 and CLK3 rs11543198 were determined using the PCR-RFLP method. Relationship between genotypes and bladder cancer risks was investigated. Results There were statistical significance in the rs2736098 genotype frequencies and allele frequencies between cases and controls (χ2= 6.973, P = 0.031; χ2= 7.412, P = 0.006). Compared with the individuals with the GG genotype , the risk of bladder cancer increased 2.069 times with the AA genotype (OR = 2.069, 95%CI: 1.181-3.624, P = 0.011). And there were no significant associations between the rs11543198 genotype frequencies and allele frequencies between cases and controls (χ2 = 0.202, P = 0.904; χ2 = 0.188, P = 0.665). Rs2736098 and rs11543198 genotype distribution in bladder cancer pathologic grade and stage had no statistical significance (P > 0.05). Conclusion Rs2736098 polymorphism is associated with risk of bladder cancer and rs11543198 polymorphism was not associated with risk of bladder cancer.
ABSTRACT
Objective To investigate the correlation of polymorphism of 8473 (T/C,rs5275) in the 3′-untranslated region of cyclooxygenase-2 (COX-2) gene with bladder cancer. Methods A case-control study on the relation between COX-2 polymorphism and bladder cancer was performed in this study. The Taqman SNP genotyping assay was used to study the COX-2 rs5275 polymorphism. Results The differences in allele or genotype distributions of COX-2 rs5275 between cases and controls (all P 0.05). Conlusion The separate effect of rs5275 polymorphism of COX-2 is associated with the susceptibility of bladder cancer, the TC/CC genotypes may be a protective factor.
