Hypothesis
What are the best management strategies for vesicoureteral reflux (VUR) associated with duplex kidney systems?
Conclusion
Surgery to correct VUR in duplex systems is highly successful, but reflux may take longer to resolve compared to single-system reflux.
Supporting Evidence
- 70% of patients with duplex kidneys presenting with urinary tract infections have VUR.
- Spontaneous resolution of low-grade VUR occurs in over half of patients.
- Surgery for VUR in duplex systems has a 98% success rate for common sheath reimplantation.
Takeaway
Some kids have a kidney problem called duplex systems that can cause urine to flow back. Doctors can help fix this, but it might take a while.
Methodology
The paper reviews existing literature and discusses management strategies for VUR in duplex systems.
Potential Biases
There may be surgeon bias and patient selection issues in the studies reviewed.
Limitations
The studies reviewed were limited by their noncontrolled retrospective nature and potential biases.
Participant Demographics
Females are more commonly affected than males, and the anomaly is bilateral in 17–33% of cases.
