Calyceal diverticula in children: unusual features and complications
Insights
Calyceal diverticula, though rare and often asymptomatic, can lead to serious complications like kidney stones and inflammatory masses. Prompt diagnosis and management are crucial for these unusual presentations.
Area of Science:
- Urology
- Nephrology
- Pediatric Surgery
Background:
- Calyceal diverticula are uncommon renal lesions.
- They are typically asymptomatic unless drainage is compromised.
- Impaired drainage can lead to significant clinical manifestations.
Observation:
- This study presents three pediatric cases with rare complications of calyceal diverticula.
- Complications included a mobile calculus within the diverticulum.
- Intrarenal inflammatory masses developed in two patients.
Findings:
- One patient presented with a mobile calculus associated with a calyceal diverticulum.
- Two patients developed intrarenal inflammatory masses.
- Diagnoses included xanthogranulomatous pyelonephritis and infected calyceal diverticulum.
Implications:
- Calyceal diverticula, despite rarity, can present with severe intrarenal complications.
- These findings highlight the importance of considering calyceal diverticula in complex pediatric renal cases.
- Early recognition and intervention are vital for managing these unusual presentations and preventing severe sequelae.
Abstract:
Calyceal diverticulum is a relatively rare lesion that is usually asymptomatic but can assume clinical significance if drainage is impaired. Three patients are presented with unusual complications directly referable to a calyceal diverticulum. One child had a mobile calculus. In 2 others, intrarenal inflammatory masses developed in the area previously occupied by a calyceal diverticulum. One of these children had proved xanthogranulomatous pyelonephritis, and the other had an infected diverticulum.
