Summary
This case study details a rare crossed fused kidney anomaly in a patient with Mayer-Rokitansky-Kuster-Hauser syndrome. Minimally invasive surgery successfully treated a large kidney stone in the anomalous kidney.
Area of Science:
- Urology
- Medical Imaging
- Congenital Anomalies
Background:
- Crossed fused renal anomalies are rare congenital abnormalities.
- Mayer-Rokitansky-Kuster-Hauser syndrome is a rare condition affecting the female reproductive system.
- Kidney stones (renal calculus) can occur in conjunction with renal anomalies.
Observation:
- A 50-year-old female with Mayer-Rokitansky-Kuster-Hauser syndrome presented with abdominal pain and burning urination.
- Imaging revealed a crossed fused kidney anomaly with a large calculus in the right renal pelvis.
- The left kidney was not visualized in its normal position, having crossed to the right side.
Findings:
- Diagnosis of crossed fused kidney with calculus disease was confirmed.
- Percutaneous nephrolithotomy, a minimally invasive procedure, was successfully performed.
- The large renal calculus was removed from the anomalous kidney.
Implications:
- This case highlights the successful management of complex renal calculus in rare congenital kidney anomalies.
- Advancements in minimally invasive surgery and imaging improve outcomes for patients with anatomical variations.
- Early diagnosis and tailored surgical approaches are crucial for managing stones in anomalous kidneys.
