Abstract

INTRODUCTION

Multicystic dysplastic kidney (MCDK) is one of the most common developmental anomalies of the kidney and it has an incidence of approximately 1 in 4300 live births. The goal of our study was to review our follow-up procedure of children with MCDK through this study via comparison of outcomes with the literature.

METHODS

Outcomes of 36 pediatric patients with antenatally detected unilateral MCDK were assessed.

RESULTS

The compensatory renal hypertrophy of the contralateral kidney was seen in 94.4% of patients and mean complete involution time was 22.97±32.63 months. Four patients underwent nephrectomy because of hypertension resistant to medication in 2 patients and parental concern in 2 patients. Vesicoureteral reflux(VUR) was the most frequent anomaly detected in 5 (13.8%) patients. VUR were low grade in all patients and any scar was not detected on DMSA.

DISCUSSION AND CONCLUSION

The results of our study showed that MCDK is a usually benign disease. Ultrasound is a noninvasive and cost effective method of choice in follow–up. A VCUG may not be routinely required in MCDK patients unless the renal US reveals suggestive of VUR or renal parenchymal defects.
