Now the ESWL is the treatment of first choice in the urinary tract stone, but it was difficult to localize the mid ureteral stone by ultrasonography. Therefore, the mid ureteral stone was treated with push back or fluoroscopic localization. The complication of the push back, such as ascending infection or ureteral penetration, were developed ocassionally. Then ultrasonic localization was considered, and insitu ESWL in 21 patients with mid ureteral stone was performed.
The results were as follows;
1) 20(95.2%) out of 21 patients with mid ureteral stone by ultrasonic localization was treated successfully
2) The size of stones was 0.5-0.9cm in 11(52.4%) patients, 1.0-1.4cm in 7(33.3%) patients and 1.5-1.9cm in 3(14.3%)patients.
3) The average sessions and shock waves of ESWL according to the stone size was 2 sessions and 2190 waves in 0.5-0.9cm, 1.83 sessions and 2133 waves in 1.0-1.4cm and 3 sessions and 3667 waves in 1.5-1.9cm, respectively.
4) Transient gross hematuria(21 cases, 100%), colic pain(2 cases, 9.5%), nausea and vomiting(2 cases, 9.5%) and steinstrasse(3 cases, 14.3%) was developed and recovered spontaneously without specific management.
The author believes that the further technical improvement of sonography made possible to successful disintegration of the mid ureteral stone.
