Results: Puncture of calyceal diverticulum was successful in all 12 UFURS patients.
Calyceal diverticulum is an abnormal cavity in the renal parenchyma.
Pediatric calyceal diverticulum treatment: An experience with endoscopic and laparoscopic approaches.
The differential diagnosis for the imaging appearance of renal tuberculosis includes chronic pyelonephritis, papillary necrosis, medullary sponge kidney, calyceal diverticulum
, renal cell carcinoma, transitional cell carcinoma and xanthogranulomatous pyelonephritis.
Initial differential diagnoses included partial staghorn stone, calyceal diverticulum with stones and chronic pyelonephritis, cystic renal cell carcinoma with calcification, TB, and fungus balls.
5) Although these findings may be "typical" of GU TB, the differential diagnoses include partial staghorn stone, calyceal diverticulum with stones, chronic pyelonephritis, cystic renal cell carcinoma with calcification, fungal infections and urothelial carcinoma.
The localization of calculi was extremely difficult in some cases with hydronephrosis, lower calyceal calculi, or calyceal diverticulum calculi.
A: Closed calyceal diverticulum with thin calyceal mucosa.
The formation of calculi or milk of calcium within a calyceal diverticulum occur secondary to a combination of urinary stasis and recurrent infection within the diverticulum.
However, when the neck of a PCD is obstructed, the diverticulum will not opacify and it is impossible to distinguish between a renal cyst and an obstructed calyceal diverticulum.
coronal and sagittal reformatted images provide valuable anatomical information and delineate the location of the calyceal diverticulum and its relationship to the collecting system to much better effect.
Calyceal Diverticulum is usually treated by surgical intervention to marsupalise the cavity or by partial nephrectomy, along with appropriate treatment of associated calculus and other coexistent complications .
