肾脏下极有一个1cm大小的灰黄*色脓肿。感染可以由尿路上行至肾（如由膀胱感染引起，称为逆行性感染，也叫上行性感染），也可以由脓毒血症时的血行播散(称为顺行性感染)而来。这种单一的脓肿可能是血行播散的。 |
In the lower pole of this kidney is a 1 cm pale yellow abscess. Infections can reach the kidney either by ascending up the urinary tract (from a bladder infection, for example) or by hematogenous spread with sepsis. This lone abscess was probably hematogenous in origin. |
