Prognoses of Multicystic Dysplastic Kidney Patients: A Single Center Experience

Introduction: In this study, was aimed to evaluate the demographic characteristics and follow-up results of patients with multicystic dysplastic kidney (MCDK) in our pediatric nephrology clinic, in the light of the literature. Material and Methods: The files of the patients who applied to the Pediatric Nephrology Clinic of Selçuk University Faculty of Medicine between January 2011 and January 2022 were analyzed retrospectively. Data of 22 patients with MCDK were recorded. Results: Twelve (55%) of the patients were left-sided and 10 (45%) were right-sided MCDK. Urinary system infection (UTI) was seen in three patients. Right-sided MCDK was accompanied by right ureterocele in one patient and hydronephrosis in the contralateral kidney in 5 patients. No urinary anomaly was observed in other patients. Proteinuria and hypertension were not detected in the patients. Vesicoureteral reflux (VUR) was not detected in 5 patients who underwent voiding cystourography. In the follow-up of the patients, MCDK was involved in a mean of 16.2±29.3 (1-107) months. Conclusion: Multicystic dysplastic kidney in children has a good prognosis with conservative management. Periodic follow-up is important to prevent the potential development of hypertension or hyperfiltration injury.
