Medical Terminology Simplified

7–78 Hydr/o/nephr/osis is an enlargement of the kidney due to constant pres-

sure from backed-up urine in the ureter. It may be caused by a stricture, tumor, or a

stone in the proxim/al part of a ureter that obstructs urine flow. When obstruction

occurs in the dist/al part of the ureter, the condition is called hydr/o/ureter with

hydr/o/nephr/osis. (See Fig. 7–8.)
