Emphysematous pyelonephritis (EPN) is an uncommon and potentially life-threatening necrotizing inflammation of the renal parenchyma. EPN associated with autosomal dominant polycystic kidney disease (ADPCK) is extremely rare. We report such a case of bilateral EPN with ADPCK that was successfully treated with conservative methods. To our knowledge, our case is only the second to document bilateral EPN occurring with ADPCK and the first one to be treated successfully with conservative methods.
Thymidine phosphorylase (TP) and dihydropyrimidine dehydrogenase (DPD) levels in transitional cell carcinoma of the bladder resected from 38 patients were examined by ELISA. TP levels in high-grade and invasive cancer were significantly higher than those in low-grade and superficial cancer, respectively. No significant differences in the DPD levels were observed among grades and stages, but the DPD/TP ratio was significantly lower in grade 3 tumor than in grade 1. These results demonstrated that 5′-deoxy-5-fluorouridine seemed to be useful for managing patients with grade 3 cancer. The present study also suggested that we might be able to exclude cases of bladder cancer in which 5-fluorouracil group medicines would be inappropriate candidates in treatment options by measuring both TP and DPD levels in the tumor.
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.
