ABSTRACT
Objective To evaluate the choice of early diagnosis method of primary ureteral neoplasms in or-der to improve the ratio of clinical diagnosis. Methods 28 cases with primary ureteral neoplasms were retrospectively analyzed. Ultrasonic examination, IVU, retrograde urogram, spiral CT, MRI, ureteroscopy and exfoliative cell examina-tion of urine were compared in this study. Results The most useful methods of detecting tumors preoperation were retrograde urogram, spiral CT, MRI, ureteroseopy. All the 28 patients underwent surgical treatment. Among them, nephroureterectomy and bladder cuff or partial resection were performed in 19 cases. Postoperative pathology showed transitional cell carcinoma in 27 cases,and adenoma in 1 case. 8 cases were T1-2 tumours. Of the 14 cases during 1990 ～1999 period, 1,5,3,2,2 and 1 cases had survival time of 1,2,3,4,5 and 6 years ,respectively. Of the 14 cases during 2000～2007,4 were lost to follow-up;2 survived for 3 years and 2 for 1 year;the other 6 who have survived near 5 years have been followed till now. Conclusions To improve the early diagnosis rate,B-ultrasonic examination, IVU,retrograde urogram,3D spiral CT and MRI examination were necessary in the early stage. The patients should be opeiated as early as possible after diagnosis.
ABSTRACT
A modified rapid microprocedure for the determination of VE in serum, was described. VE reduced Fe3+ to Fe2+ and then the Fe2+ combined with bathophenanthroline to form a pink complex -which could be determined spect-rophotometrically. As little as 0.3ml (or 0.2ml) of serum or plasma sample was sufficient for determination. The reproducibility of this method was good. The CV was 4.1% (n=15). The recoveries of added VE (0.8, 0.2 and 1.6 mg/dl) were 86.3-102.5%. The mean value and SD of 99 normal adults were 1.15+ 0.31mg/dl. This spectrophotometric method was simple and could be used in common, laboratories. Some affecting frctors were discussed.
