Presentation
Known bladder cancer, status post-radical cystectomy, and implantation of ureter conduits. The patient presents with pain in the right flank and renal angle.
Patient Data



There is mild dilatation of the right renal pelvis and ureter. Bilateral simple renal cortical cysts.



There is increased attenuation with stranding of the right renal sinus fat consistent with an inflammatory process. Mild dilatation of the right renal pelvis is also seen.
Bilateral renal cortical cysts. No other abnormality of the urinary tract is seen.
No evidence of urolithiasis and the ureteroenteric anastomosis is unremarkable.
Case Discussion
Radical cystectomy with urinary diversion is the most effective treatment for invasive bladder cancers 1. Complications of urinary diversion include anastomotic leak, urine leak and urinomas, pyelonephritis, fistula formation, ureteroenteric and neovesical-urethral anastomotic stricture, urolithiasis and worsening renal failure.
