RESUMO
Objective To investigate the clinical application and value of spiral CT(SCT) in the diagnosis of renal cell carcinoma (RCC) with inferior vena cava (IVC) tumor thrombus. Methods Spiral CT scans were performed for 4 cases clinically confirmed as RCC with IVC tumor thrombus.The imaging findings were checked with post operative pathological findings. Results RCC with IVC tumor thrombus were assessed in all the 4 patients by SCT.The carcinoma stage and the type of the tumor thrombus were also determined.Operative findings have been the same as SCT. Conclusions SCT,a non traumatic and effective method,can make accurate diagnosis of RCC with IVC tumor thrombus,providing much more information for clinical diagnosis and treatment.
RESUMO
Objective To evaluate renal plication and nephropexy in the treatment of giant hydronephrosis. Methods 18 patients with giant hydronephrosis underwent relief of the obstruction as well as renal plication and nephropexy were reviewed. Results The patients have been followed up for three months to three years and their hydronephrosis improved a lot.The effected kidney showed some recovery of function on excretory urography. Conclusions Renal plication and nephropexy can promote recovery of renal anatomy and function after the relief of obstruction.
