The authors achieved successful percutaneous extraction of urinary calculi via an intercostal approach in 24 patients. In one patient, a large hydrothorax developed and thoracentesis was required; 2 patients had moderate and 6 minimal pleural fluid collections which did not require treatment. No patient had pneumothorax. Intercostal puncture provides direct access to the upper and middle poles of the kidney when they lie above the twelfth rib and subcostal angulation is not feasible. Such an approach is advantageous for stones in the ureter, as well as renal stones which are inaccessible from the lower pole. Fluoroscopy should be performed when planning the puncture in order to avoid the lung, and a working sheath is recommended. 相似文献

AIM: To evaluate the effect of therapeutic ultrasound in the treatment of cellulitis in the maxillofacial region. PATIENTS AND METHODS: We report our experience in the management of maxillofacial cellulitis in thirty six patients using therapeutic ultrasound as an adjunct to the standard treatment. The patients were allocated to two groups: group A, treated by surgery, drugs and ultrasound therapy, and group B, where the patients were treated only surgically and medicamentously. The effect of treatment was evaluated on the basis of inflamed tissue volume reduction and normalization of tissue structure determined by ultrasonography. RESULTS: The dynamic changes in the mean values of inflamed tissue volume indicated more rapid reduction in group A in which therapeutic ultrasound was applied. Analysis of the ultrasonographic images in group A demonstrated merging of the miliary liquid foci as early as the first day of treatment. They coalesced, and this coincided with the initiation of purulent discharge. The reduction in volume was due to the accelerated elimination of breakdown inflammatory products from the tissues. CONCLUSION: The better results in group A compared with group B suggest that the method for ultrasound management was effective and could be recommended for use in clinical practice. 相似文献
