低血鉀麻痺症之臨床研究

Color Doppler Ultrasound Evaluation of the Ureteric Jet in A Patient with Completely Obstructive Uropathy Due to Ureteral Lithiasis

針對20位低血鉀麻痺症患者分析，探討甲狀腺毒性與非甲狀腺毒性麻痺症在基本資料，臨床表現及實驗室數據的差異。兩組病人在發病及入院年齡、住院日期長短、CPK及GOT值、鉀離子補充總量有明顯差異；平均血鉀濃度沒有統計意義上的差別。因此，低血鉀麻痺症患者除檢驗甲狀腺功能外，對於年齡高，女性，CPK、GOT值過高，以及鉀離子補充量偏高而血鉀濃度仍低的病患，必須進一步安排其他檢查以了解真正致病機轉。

A new technique employing color Doppler ultrasound evaluation of the ureteric jet was recently developed to observe ureterodynamic changes in patients with obstructive uropathy. We report a case (female,43-yr-old)of a right ureteral stone with complete obstruction to illustrate the usefulness of this method. The normal left ureter had a ejection velocity (Vmean)of ureteric jet of 21.3 cm/sec, a ejection duration(D)of 11.6 sec, and a ureterodynamic index(Vmean x D)of 247.08 cm：these were all within normal limits. In the bstructed right ureter, however, no ureteric jet was detected. This case illustrates that, color Doppler ultrasound valuation of the ureteric jet can be of value for detection of obstructive uropathy.
