CTU showing that after the right kidney is strengthened, the right kidney is reduced in
the parenchyma of the upper pole. The border is still clear, the cortex and medulla is
fuzzy and the surrounding renal capsule is thickened. Soft tissue shadow filling was
seen in the right renal pelvis, mildly intensified and the upper ureter was involved.
The right kidney lesion is roughly similar as that of before (18 December 2012). Urine
exfoliative cytology detected cells with nuclear atypia degeneration.

Computed tomography urography (Figure 1) demonstrated that after the right kidney is strengthened, the right kidney is reduced in the parenchyma of the upper pole.
Renal MRI-enhanced scanning: A right intrarenal occupying lesion was considered to be
more likely to be benign, about 2.7 cm x 4.4 cm in size.

Renal magnetic resonance imaging-enhanced scanning (Figure 2) observed a right intrarenal occupying lesion at about 2.7 cm x 4.4 cm in size.
Renal contrast-enhanced ultrasonography showing that the right renal masses were "slow
in and out" with moderate and high enhancement, suggesting that it was a malignant
tumor.

Renal contrast-enhanced ultrasonography (Figure 3) showed that the right renal masses were "slow in and out" with moderate and high enhancement, suggesting that it was a malignant tumor.
CTU showing that the shape of the right kidney was enlarged, and the irregular soft
tissue of the mass could be seen in the right renal pelvis and part of the renal pelvis,
mainly in the renal pelvis. The CT value of the mass was about 40 HU; after enhancement,
the CT value was about 68 HU, and the upper end of ureter was involved. The right renal
pelvis and calyceal dilated hydronephrosis. Multiple enlarged lymph nodes were seen in
the retroperitoneum. The results showed that malignancy in the right renal pelvis and
calyceal, with retroperitoneal lymphadenopathy, significantly increased compared with
that before (29 May 2013).

Computed tomography urography (Figure 4) exhibited that the shape of the right kidney was enlarged, and the irregular soft tissue of the mass could be seen in the right renal pelvis and part of the renal pelvis, mainly in the renal pelvis.
Renal MRI showing that there was a mass in the renal pelvis and calyceal of the right
kidney with severe hydronephrosis and the enlarged retroperitoneal lymph nodes.

Renal magnetic resonance imaging (Figure 5) found a mass in the renal pelvis, calyceal of the right kidney with severe hydronephrosis and the enlarged retroperitoneal lymph nodes.
Postoperative histopathologic report showing non-invasive papillary urothelial
carcinoma, low grade of renal pelvis, in a size of 10 cm x 5.1 cm x 4.5 cm, with
invasion of the ureter, and the ureteral cutting edge was not involved. No tumor
metastasis was found in the lymph nodes (0/1).

Postoperative histopathologic examination showed (Figure 6) non-invasive papillary urothelial carcinoma, low grade of renal pelvis, in a size of 10 cm x 5.1 cm x 4.5 cm, with invasion of the ureter, and no tumor metastasis was found in the lymph nodes (0/1).
