Unilateral multicystic dysplastic kidney: the case for nephrectomy

Area of Science:

• Pediatric Nephrology
• Urology
• Medical Imaging

Background:

• Unilateral multicystic dysplastic kidney (MCDK) management poses a clinical challenge, with recent literature favoring conservative approaches due to low short-term complication rates.
• Historically, surgical intervention has been considered for MCDK due to concerns regarding potential complications such as hypertension, infection, and malignant transformation.

Observation:

• This report details three pediatric cases of hypertension associated with unilateral MCDK over four years.
• One patient was lost to follow-up after ultrasound suggested resolution of the cystic kidney, underscoring diagnostic challenges.

Findings:

• The study suggests that the risk of hypertension secondary to MCDK is potentially underestimated in current clinical practice.
• Current follow-up protocols based on existing literature may lead to suboptimal patient management and missed diagnoses.

Implications:

• These findings advocate for a re-evaluation of management strategies for unilateral MCDK, emphasizing the persistent risk of hypertension.
• Elective nephrectomy is proposed as the preferred treatment option to mitigate risks associated with MCDK, ensuring comprehensive patient care.
