Clinical Report: Unanticipated Dissection of the Renal Pelvis and Ureter

Overview

Revise to specify the role of CT urography in diagnosing spontaneous dissection.

Background

Spontaneous dissection of the renal pelvis and ureter is an uncommon but significant condition that can lead to severe complications such as renal colic and hydronephrosis. Early diagnosis and intervention are crucial for preventing further renal damage and alleviating symptoms. Understanding this condition can enhance clinical management and improve patient outcomes.

Data Highlights

No numerical data available in the article.

Key Findings

• Spontaneous dissection of the renal pelvis and ureter is characterized by separation of muscularis and mucosal layers.
• The patient presented with paroxysmal colic, nausea, and abdominal pain, with urinalysis showing multiple abnormalities.
• Non-contrast CT revealed pyeloureteral dilation without calculi, indicating urinary obstruction.
• CT urography demonstrated a double-lumen sign in the right renal pelvis and upper ureter.
• Ureteral stenting provided prompt symptom relief and a favorable short-term outcome.

Clinical Implications

Clinicians should consider spontaneous dissection of the renal pelvis and ureter in patients presenting with renal colic and abnormal urinalysis, especially in the absence of kidney stones. Early imaging with CT urography is essential for accurate diagnosis and timely intervention.

Conclusion

This case highlights the importance of recognizing spontaneous dissection of the renal pelvis and ureter, as timely diagnosis and intervention can significantly improve patient outcomes.
