당뇨병 환자에서 초음파를 이용한 잔뇨측정에 관한 연구

Abstract

The presence of residual urine was determined by postvoid bladder ultrasonography in 33 diabetics and 16 normal controls. When residual urine was detected, the largest transversal (T) , longitudinal (L) , and anteroposterior (AP) dimensions (em) were determined and an index of residual urine was calculated as APxLxT. A significant correlation (r=0.97, p<O.01) was found between residual urine index and the actual volume of residual urine obtained by catheterization Residual urine was a significant finding only when the residual urine index was above 50. The prevale nee of urinary tract infection was increased in the presence of residual urine. These results confirm that ultrasonography is simple and reliable technique for detecting residual urine in diabetic patients,
