1/5. Encrusted pyelitis of native kidneys.This study reports the first four cases of encrusted pyelitis involving native kidneys. The clinical features, management, and outcome of these patients were analyzed. Predisposing factors were underlying urologic disease and/or urologic manipulations, debilitating diseases, hospitalization, and prolonged antibiotic therapies. Presenting symptoms were renal failure in three patients with ureteroileal urinary diversion and manifestations of cystitis in one patient. Computed tomography scan of the urinary tract was critical for diagnosis. Presence of struvite was demonstrated by crystalluria and infrared spectrophotometry analysis of the encrusted material. corynebacterium urealyticum urinary infection was identified in one case. Surgery (one patient) and palliative ureteral diversion (one patient), respectively, led to death and end-stage renal failure. Successful dissolution of encrusted pyelitis was obtained in two patients treated with intravenous vancomycin and local acidification of the renal collecting system. Clinical observation shows that encrusted pyelitis is a threatening disorder that destroys the native kidneys and may lead to end-stage renal failure. Successful treatment of the disease by chemolysis and antibiotics depends on correct and early diagnosis. Diagnosis required recognition of the predisposing factors, computed tomography imaging of the urinary tract, crystalluria, and identification of urea-splitting bacteria with prolonged culture on selective medium.- - - - - - - - - - ranking = 1keywords = bacterium (Clic here for more details about this article) |
2/5. corynebacterium minutissimum pyelonephritis with associated bacteraemia: a case report and review of literature.We report a case of corynebacterium minutissimum pyelonephritis with associated bacteraemia in an immunocompetent adult. The patient was successfully treated with a 14-day course of intravenous vancomycin. We review the clinical features of all the reported cases of invasive C. minutissimum infections with bacteraemia.- - - - - - - - - - ranking = 5keywords = bacterium (Clic here for more details about this article) |
3/5. Struvite stone formation by corynebacterium group F1: a case report.Struvite stones are caused by urea-splitting, usually gram-negative, organisms. A case of aggressive struvite stone production caused by corynebacterium group F1 is reported that responded to the appropriate antibiotic treatment. To our knowledge this organism has never been associated previously with struvite stone formation.- - - - - - - - - - ranking = 5keywords = bacterium (Clic here for more details about this article) |
4/5. Septicemia caused by cysteine-dependent escherichia coli.A case of septicemia and urinary tract infection caused by cysteine-dependent escherichia coli in a 70-year-old woman with bilateral staghorn calculi is described. This is the second report of a cysteine-dependent E. coli bacteremia. The bacterium was falsely susceptible to ampicillin and co-trimoxazole when tested on a medium without cysteine supplement.- - - - - - - - - - ranking = 1keywords = bacterium (Clic here for more details about this article) |
5/5. corynebacterium urealyticum (CDC Group D2) associated with staghorn calculus: treatment by percutaneous debulking and chemolysis.We report the formation of a staghorn calculus in a transplanted kidney caused by infection with a urea-splitting corynebacterium group D2 organism. The stone was debulked percutaneously followed by intravenous vancomycin administration and urinary acidification with oral acetohydroxamic acid, leading to clearance of nearly all of the stone.- - - - - - - - - - ranking = 5keywords = bacterium (Clic here for more details about this article) |
