Paraganglioma is a rare tumor of the urinary bladder. The
most affected organ is bladder in the urinary system. It accounts
for about 0.5% of all bladder tumors. These tumors are mostly
with benign but it would be malignant by 15-20%. Paraganglioma
would be safely treated with surgical approach. In this
study, we aimed to present a case of bladder paraganglioma
that stone operation was planned but incidentally detected
during percutaneous nephrolithotomy for renal stone.
A 57-year-old male patient was admitted to our clinic with left
flank pain that was lasting for approximately 6 months. The biochemical
analysis and urinalysis were normal. In the computerized
tomography(CT) of the patient; there was 30 * 33 mm
hemistaghorn stone in left kidney pelvis extending to the lower
pole with a hyperdense appearance consistent with the stone
enlarged in the middle and lower pelvis of the left kidney with
10mm diameter. There was mild dilatation in the upper urinary
tract (Figure 1) Left percutaneous nephrolithotomy operation
was planned for the patient Before the operation, cystoscopy
was performed for the insertion of a ureteral catheter.
A 1.5cm-diameter solid lesion with a polypoid appearance was
observed on the left ureteral orifice of the bladder and the
lesion was resected. The percutaneous nephrolithotomy operation
was postponed. The patient’s pathology was reported
as paraganglioma. In addition, positive staining with S100 and
negative staining with PanCK were detected (Figure 2). On the
postoperative 2nd month, left percutaneous nephrolithotomy
for left kidney stone was performed. A double J catheter was
inserted. There were residual stones after operation and an
additional operation was planned for residual stones.
