A 58-year-old man who had right hydronephrosis pointed out by medical checkup visited our hospital. Computed tomography and retrograde pyelography revealed a soft tissue mass in the middle portion of the right ureter. Urine cytology specimen from the right ureter suggested transitional cell carcinoma. Under the diagnosis of right ureteral cancer, we performed right total nephro-ureterectomy, partial cystectomy. The histopathological examination showed non-Hodgkin lymphoma (large B-cell type) of the ureter. Our diagnosis was Clinical Stage IE of the Ann Arbor Classification. The patient received only the first course of systemic chemotherapy (THP-cop), because he suffered severe thrombocytopenia in the course of the chemotherapy. No recurrence was found for 15 months after operation, and at present he is disease-free.

A 46-year-old man was admitted to our hospital complaining of macroscopic hematuria with dull pain in the right flank. Laboratory finding showed renal dysfunction and abdominal ultrasound sonograph revealed bilateral hydronephrosis (right > left). Retrograde pyelography showed left ureteral calculi and a filling defect in the middle portion of the right ureter. Renal function improved after bilateral single-J ureteral stent placement. Selective wash cytology of right renal pelvis was class II. Ureteroscopy demonstrated right ureteral obstruction with smooth-surfaced protruded tumor and cold cup biopsy was performed. Histopathological diagnosis was a fibroepithelial polyp but with no malignancy. In addition, left transurethral lithotripsy was performed under ureteroscopy. After the endoscopic examination, a double pigtail stent inserted into the right ureter. We performed conservative management by repeat urine cytologies and retrograde pyelography due to thrombocytopenia. The urine cytologies all proved negative and retrograde pyelography showed no abnormal changes. A ureteroscopic procedure is considered to be useful for the diagnosis of ureteral polyps. Transurethral resection of ureteral polyps with a ureteroscope is recommended for treatment.

TAR syndrome is a congenital malformation syndrome characterized by bilateral absence of the radius and thrombocytopenia. The known urinary anomalies are duplex ureter, dilatation of renal pelvis, horseshoe kidney and functional problems like vesicoureteral reflux and pyelonephritis. In this report of a case with TAR syndrome, a kidney stone and bladder telangiectasia were found coincidentally during the investigation of hematuria. TAR syndrome is discussed in the light of the medical literature. To our knowledge, no case has been reported demonstrating nephrolithiasis and bladder telangiectasia in TAR patients.

Idiopathic thrombocytopenia (ITP) is a bleeding disorder involving the destruction of platelets by the immune system. Systemic amyloidosis is another bleeding disorder involving amyloid deposits that create defects in coagulation and increased prothrombin and thrombin times. We report a 52-year-old man with ITP and new two-month-duration, painless gross hematuria without clot formation resulting in amyloidosis involving the ureterovesical area of the bladder. He had osteopenia, hypertension, and moderate thrombocytopenia due to ITP diagnosed 7 years previously. Cystoscopic examination with urine cytology and computed tomography imaging detected a 2-cm protruding solid bladder mass involving the left ureteral orifice and trigone and left mild hydroureteronephrosis, suggesting bladder cancer. Transurethral resection of the bladder mass was performed to confirm amyloidosis involvement in the ureterovesical junction of the bladder and ureter. Four weeks postoperatively, intermittent gross hematuria remained; hence, left ureteroneocystostomy was performed. Regular follow-up showed no signs of hematuria or intravesical recurrences for 14 months.
