Acquired cystic disease of kidney in chronic renal failure in Jordan

Abstract EN

Acquired cystic disease of the Kidney (ACDK) is a well documented complication of end stage renal failure in patients managed conservatively or supported by dialysis.

The aim of the present study is to highlight the scope of the problem among our patients, and to evaluate the clinical characteristics of the disease.

A Total of 124 patients with chronic renal failure (106 on dialysis, 18 non-dialyzed) were studied with ultrasonography by the same radiologist.

ACDK was defined as the presence of four or more cysts in each kidney.

The cysts should have sharp smooth wall with acoustic enhancement.

In non-dialyzed patients, 5.5% had ACDK, 33.5% had one to three cysts and 61% had no cysts.

Among dialysis patients 42.5% had ACDK, 26% had one to three cysts and 31.1% had no cysts.

During of dialysis therapy and age were greater in patients with ACDK (74 ± 30 months.

58 ± 3 years respectively) compared to those with no cysts (11 ± 8 months.

26 ± 4 years).

The major clinical complications were intracystic hemorrhage in three cases and stones in seven cases.

No correlation was noted between the presence of cysts and the original kidney disease, gender, hematocrit or adequacy of dialysis.

We conclude that, ACDK occurs commonly in patients with chronic renal failure; however, patients are generally older and have been on dialysis longer than patients without cysts.

Ultrasound, in the hands of an experienced radiologist, is a relatively adequate screening tool for ACDK and its complications.
