Helical CT and 3D reconstruction of ureteropelvic junction obstruction: accuracy in detection of crossing vessels.

PURPOSE: The purpose of our study was to evaluate the accuracy of 3D helical CT and its value in surgical planning for the treatment of ureteropelvic junction obstruction (UPJO). METHOD: CT scans and 3D reconstruction of renal vessels and the renal pelvis were performed in 20 cases of UPJO treated by open surgery. We analyzed scans in search of a vessel at the junction and its position relative to the UPJ. Helical CT scans and 3D reconstructions were correlated with macroscopic surgical findings. RESULTS: CT scans demonstrated the presence of a UPJO in all cases. Crossing vessels were present at the junction in 13 of 20 cases. The vessel crossed the junction posteriorly in six cases and anteriorly in seven cases. Macroscopic surgical findings were in agreement with helical CT reconstructions in 100% of the cases. CONCLUSION: Axial scans together with 3D reconstruction are an accurate way of detecting crossing vessels when UPJO occurs, and the choice of the most adequate surgical technique is facilitated.

[Destroyed lung (author's transl)].

The expression of "destroyed lung" is, now, accepted to designate the large destructions of the lung, secondary to pulmonary and essentially infectious diseases, the cure of which is obtained but with important sequelae. The main cause remains tuberculosis, cured by chemotherapy. Some large pulmonary suppurations, treated by antibiotics, can lead to the same sequelae. These "destroyed lungs" can keep an asymptomatic form. But often, about ten years after the initial disease, they cause several troubles such as progressive dyspnea leading to irreversible respiratory insufficiency, repeated pulmonary infectious episodes and hemoptysis, the risk of which is increased by aspergillosis. The radiological aspect of these "destroyed lungs" is made of opacities with multiple cavities or with one unique large cavity. The mechanism of hemoptysis has been understood recently: all destructive lesion of the pulmonary tissue produces as a consequence a development of the systemic blood circulation, bronchial or parietal, with reverse blood circulation from systemo-pulmonary anastomoses-which can produce capillary dilatations-into the pulmonary artery. All these complications can lead to a surgical treatment. Embolization of bronchial arteries is a less aggressive method when hemoptysis is the main symptom. These acquires "destroyed lungs" can be compared to those caused by extensive pseudokystic bronchiectases. For both cases clinical aspects and therapeutic methods are similar, though the lesions are fixed and likely congenital in the last form.

[Diffuse peritoneal lymphoma in AIDS].

We report an unusual observation of peritoneal localisation in a non-Hodgkin lymphoma, the only sign of digestive injury. This peritoneal injury may be more frequent with AIDS patients, as in our observation. Tomodensitometry was the best exam to visual this injury.
