Urinoma post-nephrostomy

Case contributed by Dr Bruno Di Muzio


Bilateral nephrostomy due to bladder TCC.

Patient Data

Age: 56-year-old
Gender: Male


Bilateral nephrostomy in situ with their loops curled in the renal pelvises. There is a subcapsular perirenal collection along the anterior surface of the right kidney with low homogeneous attenuation that demonstrates contrast leaks into it on the delayed phase consistent with a urinoma. This mildly distorts the underlying kidney. A small amount of free fluid in the left perirenal space. The kidneys are otherwise normal in appearances, with no calculi or focal mass. Both ureters are dilated. There is excretion of contrast into the renal calyces and pelvises on the delayed phases, however, even on the 10 min delayed phase, there is no excretion of contrast into the ureters or bladder.

Case Discussion

Peri-renal urinomas have been reported after procedures such as percutaneous nephrostomy, as showed in this case.
