Case | DMSA | Renal CT | Renal US |
|---|---|---|---|
Case 1 | Right kidney: Relatively Reduced volume, Split renal function 61% Left kidney. Cortical scarring at the upper pole & large photopenic area in the lower pole with Split renal function 39% | Right kidney: large staghorn branching stone on the renal pelvis Left kidney: left renal lower pole stone | Right kidney: grade 3 hydronephrosis Left kidney: grade 2 hydronephrosis Bilateral multiple renal stones. |
Case 2 | Right kidney small with decrease uptake and small scar Left good kidney uptake with split renal function 92% | Right kidney: Atrophic small right kidney with at least two calculi at its lower pole Left kidney: A tiny calculus at the left vesicoureteric junction. | Right kidney: Small size, lower pole mild to moderate hydronephrosis. Left kidney: non-obstructing calculus noted at the lower pole with mild hydronephrosis. |
Case 3 | Right kidney: obstructive right periureteric junction stone with moderate hydronephrosis. Left kidney: normal | Right kidney: calculi in the pelvis with moderate hydronephrosis. | |
Case 4 | Right kidney: large stone in the renal pelvis. Small calculus in the lower pole of an atrophic, small kidney. Left kidney: large calculus in the left renal pelvis. Severe hydronephrosis and thinning of the cortex. Multiple non-obstructing calculi seen in the lower pole. | Right kidney: grade 2 hydronephrosis, multiple non-obstructing stones. Left kidney: grade 4 hydronephrosis with thin renal parenchyma and an obstructive stone | |
Case 5 | Bilateral renal stones | ||
Case 6 | Normal right kidney according to DMSA scintigraphy, with reduced left kidney function, hydronephrotic changes, and a scar. | Right kidney: normal Left kidney: multiple stones and grade 1 hydronephrosis. | |
Case 7 | Left non-obstructive renal stones. | ||
Case 8 | Right Kidney: Calculi in the pelvis Left Kidney: Normal |
