Flashcards in 36. Hydronephrosis Deck (10):
1

Definition

distention / dilation of renal pelvis and calyces

2

causes of hydronephrosis

-usually caused by urinary tract obstruction ( stones, PBH, cervical cance, injury to ureter_
-other causes --> retroperitoneal fibrosis, vesicourateral reflex

3

hydronephrosis dilation occurs ..(location)

proximally to the site of pathology

4

hydronephrosis leads to ... ( apperance )

compression and possible atrophy of renal cortex and atrophy

5

hydronephrosis - serum creatinie elevation?

only if obstruction is bilateral or if patient has only one kidney

6

hallmark of nephritic syndrome

glumerula inglammation and bleeding

7

• What is hydronephrosis?

Distention/dilation of renal pelvis and calyces, usually as a result of another disease process

8

• A man with chronic unilateral ureter stenosis exhibits hydronephrosis with high creatinine. Why is the creatinine level rising?

He likely only has one kidney—with no second kidney to compensate for the obstruction, filtration is impaired and creatinine rises

9

• Name some causes of hydronephrosis.

Urinary tract obstruction (e.g., renal stones, BPH, cervical cancer, injury to ureter), retroperitoneal fibrosis, vesicoureteral reflux

10

• A patient has chronic unilateral kidney stones that are causing ipsilateral hydronephrosis. Where will pathologic dilation be seen?

The proximal ureter and kidney—dilation always occurs proximal to the site of pathology
