From the Guidelines
The management approach for worsening Chronic Kidney Disease (CKD) with possible renal duplication anomalies requires a comprehensive strategy focused on slowing disease progression and addressing anatomical concerns. Initial steps should include optimizing blood pressure control with ACE inhibitors (such as lisinopril 10-40 mg daily) or ARBs (such as losartan 50-100 mg daily), which provide renoprotective effects beyond blood pressure reduction by decreasing intraglomerular pressure and proteinuria 1. Glycemic control is essential for diabetic patients, targeting HbA1c below 7% using medications with proven renal benefits like SGLT2 inhibitors (empagliflozin 10-25 mg daily or dapagliflozin 5-10 mg daily) when eGFR permits 1. Some key points to consider in the management of CKD with possible renal duplication anomalies include:
- Dietary modifications including sodium restriction (<2g/day), protein moderation (0.8g/kg/day), and potassium restriction in advanced stages are crucial.
- For patients with renal duplication anomalies, urological evaluation with comprehensive imaging (renal ultrasound, CT urography, or MR urography) is necessary to assess for complications like obstruction, reflux, or recurrent infections that may accelerate CKD progression.
- Regular monitoring should include quarterly assessment of renal function, electrolytes, and proteinuria, with referral to nephrology when eGFR falls below 30 ml/min/1.73m² or earlier with significant proteinuria.
- Urological intervention may be required for anatomical complications, ranging from minimally invasive procedures to surgical correction depending on the specific duplication anomaly and its contribution to worsening kidney function. The significance of possible duplication anomalies in the context of worsening CKD lies in their potential to contribute to disease progression through complications such as obstruction, reflux, or recurrent infections, highlighting the need for a comprehensive management approach that addresses both the CKD and the anatomical concerns 1.

From the Research
Significance of Possible Duplication Anomalies
- Possible duplication anomalies in the context of worsening Chronic Kidney Disease (CKD) refer to congenital abnormalities of the urinary tract, where a kidney may have two separate collecting systems, each with its own ureter 2.
- The presence of duplication anomalies can increase the risk of urinary tract infections, kidney stones, and other complications that may worsen CKD 2.
- Renal ultrasound is a key diagnostic tool for detecting duplication anomalies, and it can also help identify other potential causes of CKD progression, such as hydronephrosis or renal artery stenosis 3.
Management Approach for Worsening CKD with Possible Duplication Anomalies
- The management approach for worsening CKD with possible duplication anomalies involves a comprehensive evaluation of kidney function, urinary tract anatomy, and potential complications 4.
- Cardiovascular risk reduction, treatment of albuminuria, and avoidance of potential nephrotoxins are essential components of CKD management 4.
- Imaging studies, such as ultrasound, CT urography, or MRI, may be used to evaluate the urinary tract and detect potential complications, such as obstruction or kidney stones [(5,6)].
- Patients with CKD and possible duplication anomalies may require closer monitoring and referral to a nephrologist for specialized care 4.
