In 45 patients with ureteral calculi 2 to 8 mm in diameter, attempts were made to remove the stones transurethrally, using a Dormia extractor and television fluoroscopic monitoring. The procedure was successful in 34 patients. The success rate was 74% when the stones were 5 mm or less and 68% with the larger stones. In 10 patients when instrumental extraction failed, this was followed immediately by open surgery, for removal of stone. The reasons for failure of the transurethral procedure are presented. Great care in performance and preparedness for open surgery are always required, especially when the stone is large. Television facilities should be good and include image intensifier. There were no serious complications of instrumental or surgical removal of calculi.
Tibial torsion was assessed fluoroscopically in 38 patients with unilateral tibial fractures. Measurements were performed bilaterally after fracture reduction and stabilization. The difference in torsion between the respective tibias of each subject was calculated, and the result was compared with the values obtained from measurements in 100 normal adults with the same fluoroscopic method. A tibial torsion difference exceeding the normal mean +/- SD was found in 26 patients. The maximum difference was 49 degrees, as compared with 15 degrees in normal adults. In order to reduce the risk of disabling malrotation, measurement of tibial torsion in the operating room is recommended.
The authors described a fluoroscopic method of guiding percutaneous needle penetration of the foramen ovale. The advantages are simplicity, speed, accuracy, and comfortable patient positioning. Radiation exposure is minimized.
