INTRODUCTION: Synchronous metastases of the ureter and renal
pelvis are rarely seen in RCC(Renal cell carcinoma).In this case report,
we aimed to present a case of synchronous RCC metastases to
ipsilateral ureteral and renal pelvic detected after radical nephrectomy
for right renal mass.
CASE: A 69-year-old male patient presented with hematuria.There
was no lesion on the cystoscope.Approximately 10 cm mass lesion
which extended from the upper and middle right kidney to the renal
pelvis and proximal ureter, was seen on abdominal computed tomography
(CT).Also left renal vascular tumor thrombus was observed.
Right radical nephrectomy, right ureterectomy and lymph node dissection
were applied to the patient. Right radical nephrectomy material
was reported as RCC subtype, clear cell carcinoma, furhman grade
grade 3. RCC metastases to renal pelvic and ureter which located on
pathology specimen.
DISCUSSION: Approximately 70% of kidney tumors are detected
incidentally. Primer RCC is well known for its unpredictable biological
behavior, early metastatic propensity and metastatic potential. It is
reported that about one third of patients with BCC can develop with
metastases. Our case is a case of RCC who metastases synchronous
ureter and renal pelvic as a result of postoperative pathology. Despite
the presence of left renal vein thrombus, there was no tumor formation
in the left kidney and collecting system.
RESULT: The genitourinary system is one of the rare areas of RCC
metastasizes. Synchronous renal pelvis and ureteral metastases are
very rare. The mechanism of metastasis is not fully understood. For
this reason, further study is necessary.
