We report a case of retroperitoneal Castleman’s disease of the hyaline vascular type. The tumor was excised with the left kidney because of tenacious adhesion to the renal pedicle. We suggest that knowledge of Castleman’s disease in the retroperitoneal area would help to avoid an unnecessarily extensive operation.
Kesidtial microiragmcnfs after ESWL were studied for their presence and for possibility of dissolution with citrate therapy. Among 123 patients with renal stones who became stone-free following ESWL, a computed toiiiogr.ini (CT) itientifiecl remaining microfragments within the treated kidney in 31.7% of the patients, even though stone fragments were not detectable on ordinary x-ray (KUU). The experiments, in which calcium oxalate stone fragments c-ollected li citrate administration than in control urines. Eighteen patients with microfragments underwent a follow-up CT I months later, The rcsults showed that thc microfragments had disappeared in 6 of 11 (53.5%) p-'.itients who had beer1 t,iking .11kaIi citrate, whereas microfragments remained unchariged in all 3 patients wlthout niedication. Our results suggest that citratr therapy would be advisable as d prophylaxis tor stone recurrence especially after ESWL treatniriit. Int J Urol 1996;3(suppl 1 ):S85-S87
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
