RESUMEN
OBJECTIVE@#To evaluate the diagnostic value of color Doppler flow image (CDFI) for the diagnosis of Budd-Chiari syndrome (B-CS).@*METHODS@#CDFI findings of 35 patients with B-CS were retrospectively analyzed and compared with the findings of venography of inferior vena cava (IVC).@*RESULTS@#Thirty-four patients were diagnosed as B-CS by CDFI, while one patient with local tunica stenosis was misdiagnosed. The correct diagnostic rate was 97.1%. In the 34 patients, CDFI displayed stenosis or occlusion in the hepatic vein and IVC in 24 patients, IVC only in 8,and hepatic vein only in 2.@*CONCLUSION@#CDFI may be a principal non-invasive technique to diagnose B-CS.

Objective To evaluate the feasibility and efficacy of percutaneous nephrolithotomy (PCNL)in treating renal calculi.Methods The data of 118 patients with renal calculi who had underg- one PCNL from July 2002 to August 2004 were retrospectively analyzed.There were 86 men and 32 women. The mean age was 39 years(range,7-68 years).Of the 118 cases,11 had pelvic calculi,16 had calyx cal- culi,35 had pelvocalyceal calculi,54 had staghorn calculi,and 2 had bilateral renal calculi.The mean stone size was 2.5 cm?1.5cm(ranged from 2.0 cm?1.0 cm to 4.5cm?4.0cm).Results Of the 118 ca- ses,112 underwent one-stage PCNL,and 6,two-stage PCNL.The procedure was performed by single tract in 114 cases,and by two tracts in 4 cases.Lithotomy was done by one session in 60 cases,by 2 sessions in 42 cases,and by 3 sessions in 16 cases.The total stone clearance rate was 81.4%.The mean operative time was 120 min,and mean hospital stay was 15 d.No blood transfusion was needed during operation,and only one patient experienced bleeding(about 500 ml)after 4 d postoperatively,and was cured by conservative treat- ment such as blood transfusion and anti-inflammation.No major complications were observed in other pa- tients.Conclusions PCNL has advantages of minimal trauma,less blood loss,fewer complications,and is safe and effective in treating renal calculi,especially for patients who will have the second procedure.
