Lacunae: a urographic finding in chronic obstructive uropathy.

Abstract

Lacunae, small spaces in the renal sinus that communicate with the caliceal fornices, have been mentioned rarely in the radiologic literature. These lesions have been reported to opacify during excretory urography in patients with current or previous urinary obstruction. Lacunae have been presumed to form in response to urine extravasation through the fornices, but there has never been gross anatomic or histologic proof of their existence. In two patients with obstructive uropathy, urographic-pathologic correlation confirmed the existence and nature of lacunae. On excretory urography, the appearance is likely to be confused with papillary necrosis.

The long-term effect of multidisciplinary back training: a systematic review.

STUDY DESIGN: Systematic review of randomized controlled trials. OBJECTIVES: To determine the long-term effect of multidisciplinary back training on the work participation of patients with nonspecific chronic low back pain. SUMMARY OF BACKGROUND DATA: Chronic low back pain is influenced by multiple factors. Multidisciplinary back training represents one of the options to take this multiplicity into account. So far, only evidence of the short-term effectiveness of this approach in terms of work participation is available. METHODS: Electronic databases were searched and the references of various articles were screened for relevant publications. Ten studies met the inclusion criteria. All included studies were evaluated for their methodologic quality. RESULTS: Five of the studies had a low methodologic quality. All high-quality studies found a positive effect on at least one of the 4 outcome measures used. Based on our criteria, effectiveness was found for the outcome measures of work participation and quality of life. No effectiveness was found for experienced pain and functional status. The intensity of the intervention seems to have no substantial influence on the effectiveness of the intervention. CONCLUSION: In the long-term, multidisciplinary back training has a positive effect on work participation in patients with nonspecific chronic low back pain.
