Abstract

|
Many factors have been concerned about spontaneous passage of ureteral stones. Patients of ureteral stone ask to doctor the day of passage of ureteral stone and then doctors cannot suggest satisfiable answer. I investigated the relation between duration and many factors which concerned about spontaneous passed out urethral stones. One hundred fifty cases of spontaneous passed out ureteral stones were evaluated during 5 years between October, 1993 and October, 1995. We investigated relation between duration of spontaneous passage and size, position, shape, margin, density, IVP
findings of ureteral stones. The size and position influenced the duration of spontaneous passage of ureteral stones and other factors showed no significant difference. Small size in same position and low position in same size of ureteral stones were passed out spontaneously more early. Average duration of spontaneous passed out ureteral stone was 2.5 days in 2㎜, 5.1 darts in 3㎜, 4.3 days in 4㎜, 7.2 days in 5㎜ and 2.7 days in ureterovesical junction(UVJ), 4.1 days in lower ureter, 7.6 days in upper ureteral stones. This investigation suggested average duration of spontanous passed out ureteral stones for size and position and also suggested that many other factors showed no difference in spontanous passage of ureteral stones. With this results, we can suggest relatively accurate duration of spontaneous passage of ureteral stone.
