Emptying time means the time it takes to excrete the whole contents which entered the pelvis of the kidney.
I have studied 42 cases of nephroptosis patients at our department. In kidneys with delayed emptying time, the degree of ptosis, inversion, enlarged renal pelvis, ureter flexion, etc. Were studied and the following results were obtained.
1) 26 persons (61.9%) had delayed emptying time.
2) Among the 26 persons, only the right kidney delayed were 7 persons (26.9%), only the left kidney delayed were 5 persons (19.2%), and both kidneys delayed were 14 persons (53.8%).
3) The delayed emptying time did not have any direct connection with the degree of ptosis. Among the variation in the kidney and ureter, the ureter flexion (including the flexion at the ureteropelvic junction) has much connection and Narath's symptom could be seen in some cases.
4) In the left side delayed cases, the degree of ptosis, the variation of the kidney and ureter was little compared to the right side cases.
5) As an whole, the emptying time delaying was more in the bilateral cases compared to the unilateral cases.
