A case of synchronous ipsilateral renal cell carcinoma and transitional cell carcinoma]

A case of synchronous ipsilateral renal cell carcinoma with renal pelvic and ureteral transitional cell carcinoma is reported. A 80-year-old man, who had had transurethral resection of bladder tumor three times, was admitted on August, 1989 for recurrence of bladder tumor. Excretory pyelography revealed a filling defect of left renal pelvis. Findings of retrograde pyelography and computed tomography were in accord with those of the excretory urograms. Under a diagnosis of the left renal pelvic and ureteral tumor associated with the bladder tumor, left nephroureterectomy with bladder cuff resection was performed. Pathological diagnosis was renal pelvic and ureteral transitional cell carcinoma with renal cell carcinoma, which existed incidentally in the same kidney. Double unrelated primary carcinoma in urinary tract, especially, double dissimilar primary carcinoma in the same kidney, is rare. To our knowledge, this case is the 20th double cancer in upper urinary tract reported in Japan.     

Simultaneous bilateral renal pelvic tumors: a case report]

A case of simultaneous bilateral renal pelvic tumors is reported. A 64-year-old man with the chief complaint of gross hematuria and left flank pain was admitted. Clinical investigations revealed a tumor in the right pelvis and ureter, and another tumor in the left renal pelvis. The right ureteral tumor had invaded the bladder. Right nephroureterectomy, total cystectomy, left partial pyelectomy and ureterocutaneostomy were performed. By pathological examination, right renal pelvic and ureteral tumors were non-papillary transitional cell carcinoma, grade 3, pT4, and the left renal pelvic tumor was papillary transitional cell carcinoma, grade 2, pT1. To our knowledge, this is the 16th case of simultaneous bilateral urothelial tumors of the upper urinary tract in Japan.     

Primary mucosa-associated lymphoid tissue (MALT) lymphoma of the urinary bladder associated with left renal pelvic carcinoma: a case report

We report a case of primary mucosa-associated lympoid tissue (MALT) lymphoma of the urinary bladder associated with left renal pelvic carcinoma. A 84-year-old woman showed microscopic hematuria during follow up for hypertention. Left renal pelvic tumor was found and she was referred to our hospital for further evaluation and managemant. She showed pyuria and Escherichia coli was detected by urine culture. Intravenous pyelography and computed tomography revealed the left renal pelvic tumor and solid bladder tumor. Transurethral resection of bladder tumor and left total nephroureterectomy were performed. Histologically, the left renal pelvic tumor was urothelial carcinoma > > adenocarcinoma, G2, pT2 and the bladder tumor was MALT lymphoma. Ga-scintigraphy showed no hot uptake suspicious of metastatic lesion. Then, external beam radiotherapy (36 Gy) was performed to the urinary bladder. She has been alive for 14 months with neither renal pelvic tumor nor MALT lymphoma showing any evidence of disease progression.     

A Case of Renal Cell Carcinoma Associated with Synchronous Contralateral

We report a case of renal cell Carcinoma associated with synchronous contralateral renal pelvic cancer and bladder tumor. The patient underwent total nephroureterectomy for the left renal pelvic cancer with transurethral resection of the bladder tumor. After 2 courses of combination chemotherapy, we performed surgical enucleation of the right renal cell carcinoma. Although transurethral resection of the recurrent bladder tumors was undergone 17 months after the last operation, the patient retains normal renal function.     

Triple cancer in the urinary system: a case report

A 74-year-old male was referred to our hospital due to microhematuria that was pointed out at his health check-up. Cystoscopy showed many papillary bladder tumors under 5 mm in size. Intravenous pyelography also showed deformity of the right kidney and shadow defects in the left renal pelvis. Abdominal computed tomography revealed an 8 cm tumor invading the renal vein in the right kidney, and a 3 cm tumor in the left renal pelvis. Prostate biopsy was performed with PSA 3.4 ng/ml, and he was also diagnosed with prostate carcinoma. First, he received right radical nephrectomy, and secondly left nephroureterectomy and cystectomy. Our case should be called triple cancer because bladder cancer was thought to be daughter tumor of renal pelvic tumor. This is, to our knowledge, the 11th case report that occurred in the urinary tact, and the first case that needed total resection of urinary tract.     

A case of bladder cancer with bilateral ureteral carcinoma in situ

A case of bladder cancer with bilateral ureteral carcinoma in situ (CIS) is presented. A 55-year-old male had gross hematuria and urinary retention. Cystoscopy revealed diffuse broad-based papillary tumors, which proved to be transitional cell carcinoma (G2) with CIS and submucosal invasion microscopically. Excretory urography showed normal upper urinary tracts except stasis of bilateral lower ureters. Neither lymph node swelling nor distant metastasis was found by computed tomography. Therefore the patient underwent total cystourethrectomy, pelvic lymph-adenectomy, and construction of an ileal conduit. Histological examination of the specimens demonstrated CIS on bilateral ureteral stumps on the renal side, which, however, was not continuous to that of the bladder. Much attention should be paid to upper urinary tracts for ureteral lesions before cystectomy in such bladder tumors and the proximal stump of the ureter should be examined using frozen section at the operation, but these were not sufficient in the present case in which skip lesions of the ureters were seen apart from the bladder.     

Adenocarcinoma of the renal pelvis and transitional cell carcinoma of the ureter occurring 11 years after radical cystectomy for bladder cancer: a case report

We report a case of upper urinary tract carcinoma which recurred 11 years after total cystectomy. A 52-year-old man presented with complaints of a sense of residual urine and terminal miction pain. Urinary cytology, cystoscopic examination and intravenous pyelography revealed normal findings. Twenty months later, because class V urinary cytologic findings were detected, transurethral biopsy was performed. Carcinoma in situ was diagnosed pathologically. Therefore, total cystectomy and ileal conduit urinary diversion were performed. The pathological diagnosis was transitional cell carcinoma, grade 3, pTis. At 127 months postoperatively, laboratory examination revealed an extremely high serum level of LDH (3,084 U/l). The right kidney was not visualized on IVP and computed tomography revealed a right renal irregular mass. On the suspicion of a renal pelvic tumor, right total nephroureterectomy was done. The pathologic diagnosis was renal pelvic adenocarcinoma and ureteral transitional cell carcinoma. The patient was treated postoperatively with 3 cycles of systemic chemotherapy and radiotherapy. The serum level of LDH returned to normal. However, one year later, the serum level of LDH elevated to 1,118 U/l. He died of retroperitoneal lymph node, left adrenal gland and pulmonary metastases.     

A case of double cancer: renal cell carcinoma and transitional cell carcinoma of urinary bladder

This is a case report on a patient with double cancer of kidney and urinary bladder. The patient was a 65-year-old female, and she was admitted with the chief complaint of gross hematuria and right flank pain. After careful examinations, she was diagnosed with right nonfunctioning kidney caused by invasive bladder cancer. Computerized tomography incidentally revealed a mass in the upper pole of the left kidney. Selective left renal arteriography showed stretched arteries and irregularity and tortuosity of the smaller vessels. She was diagnosed with double cancer of bladder and left kidney. Owing to the damage of the right renal function, left partial nephrectomy, total cystectomy, right nephroureterectomy and left ureterocutaneostomy were performed. According to DMSA scintigraphy measured 15 days later, the uptake value of the left kidney was 13.25%, compared to the preoperative value of 25.62%. To date, this case is 36th reported case in Japan.     

Bellini duct carcinoma of the kidney: a case report

A case of Bellini duct carcinoma is reported. A 70-year-old man visited our hospital because of gross hematuria and left flank pain. Although no abnormality was found on ultrasonography, drip infusion pyecography, computed tomographic scan and cystoscopy. However class IV was suspected based on urinary cytology. Magnetic resonance imaging showed an irregular pattern in the left upper kidney. Ureterscopic biopsy revealed transitional cell carcinoma and class V was suspected on the urinary cytology of the left renal pelvis. Under the preoperative diagnosis of a left renal pelvic tumor, left nephroureterectomy was performed. The histopathological diagnosis with immunohistostaining was Bellini duct carcinoma. No evidence of recurrence or metastasis was noted 9 months after surgery without any adjuvant therapy.     

Prognostic variables in patients with transitional cell carcinoma of the renal pelvis and proximal ureter

Recent technological advances in urological endoscopic surgery of the renal pelvis and proximal ureter via ureteroscopy or percutaneous nephroscopy have made it possible to consider parenchymal-sparing procedures in patients with transitional cell carcinoma. To define the role of these procedures in the management of renal pelvic or proximal ureteral transitional cell carcinoma we analyzed retrospectively 31 patients who underwent nephroureterectomy for transitional cell carcinoma of the renal pelvis and/or proximal ureter. High grade upper urinary tract transitional cell carcinoma and a history of metachronous or synchronous bladder transitional cell carcinoma were independent adverse prognostic factors. However, patients with low grade upper urinary tract transitional cell carcinoma and no evidence of a urothelial field change had a 100 per cent 5-year survival rate. It would appear that parenchymal-sparing endoscopic techniques should be regarded with caution in patients with either high grade transitional cell carcinoma of the renal pelvis and proximal ureter or a history of bladder cancer.     

Spontaneous disappearance of multiple lung metastases after nephroureterectomy from sarcomatoid carcinoma of the renal pelvis: A case report

We report a case in which lung metastases disappeared spontaneously after nephroureterectomy from sarcomatoid carcinoma of the renal pelvis. A 58-year-old man presented with gross hematuria. Computed tomography (CT) revealed a left renal tumor and multiple lung metastases. Intravenous pyelography revealed a filling defect in the upper renal calyx. Urine cytology was positive. Left renal pelvic cancer was diagnosed and nephroureterectomy performed. The resected specimen was diagnosed pathologically as sarcomatoid carcinoma of the renal pelvis. Approximately 5 months later, CT revealed that the lung metastases had disappeared. There has been no evidence of disease for 46 months postoperatively.     

A case of urothelial tumors which occurred simultaneously in bilateral upper urinary tracts and bladder presenting with anuria]

A 72-year-old male was admitted with a chief complaint of anuria. Clinical examinations showed that he was in uremic state and had bilateral hydronephroses. An endoscopic examination revealed a left ureteral tumor and a bladder tumor. Left nephroureterectomy with partial cystectomy and transurethral resection of the bladder tumor were performed. Pathological examinations showed an invasive left renal pelvic tumor (pT3, G3), an invasive left ureteral tumor (pT4, G3), and a bladder tumor (pTis, G3). Following the operation, roentgenological and urinary cytological findings showed a right ureteral carcinoma. He died of multiple liver and bone metastases and local recurrence at 5 months postoperatively.

A case of signet ring cell carcinoma of the urinary bladder

A case of primary signet ring cell carcinoma of the urinary bladder is reported. A 52-year-old man was admitted with the complaint of gross hematuria. Cystoscopy showed non-papillary tumor on the right lateral wall. Abdominal CT, Ga scintigraphy, upper gastrointestinal series and barium enema, revealed no signs of a tumor other than the bladder carcinoma. The routine hematologic and chemistry profiles showed no abnormalities except for the serum level of carcinoembryonic antigen elevated to 210 ng/ml. Total cystectomy and right nephroureterectomy with left cutaneous ureterostomy was performed and the surgical specimen showed adenocarcinoma of the bladder. The patient died 5 months after the operation, and autopsy was performed. No tumors were found on the mucosa of the whole digestive tracts or pancreas. This case might be of primary adenocarcinoma originated from the bladder. The literature on the differential diagnosis of the cases reported as bladder adenocarcinoma are reviewed briefly.     

Synchronous triple urogenital cancer (renal cancer,bladder cancer,prostatic cancer): a case report

A case of synchronous triple urogenital cancer, which was comprised of renal cell carcinoma of the left kidney, transitional cell carcinoma of the urinary bladder, and adenocarcinoma of the prostate, is reported. A 72-year-old Japanese male patient was referred to our outpatient clinic with the complaint of asymptomatic hematuria. At that time, his serum of level of PSA was elevated to 20 ng/ml. Cystourethroscopy showed a papillary bladder tumor and coagula through the left urinary orifice. Ultrasonography, computed tomography and magnetic resonance imaging showed a mass lesion measuring about 6 cm by 5 cm in the left kidney. Angiography showed a hypervascular lesion measuring about 6 cm by 5 cm at the same site. Double cancer, consisting of renal cell carcinoma and transitional cell carcinoma of the urinary bladder, was suspected and we performed left total nephroureterectomy, hilar lymphadenectomy, and transurethral rection of the bladder tumor, one month later. At the same time, we performed a biopsy of the prostate. Histological diagnosis was renal cell carcinoma, clear cell carcinoma and transitional cell carcinoma of urinary bladder. Histological diagnosis of the prostate biopsy was moderately differentiated adenocarcinoma. Since this case fulfilled the criteria of Warren and Gates, it was classified as synchronous triple urogenital cancer. A review of the literature revealed 17 authentic cases of triple urogenital cancer, of which 14 and 10 cases were reported as a combination of renal cancer, bladder cancer and prostatic cancer, in the world and in Japan, respectively. Furthermore, he had been exposed to the atomic bomb explosion in Hiroshima in 1945. This carcinogenic precursor may be related to the development of the triple cancer.     

Transitional cell carcinoma of the renal pelvis in a patient with cyclophosphamide therapy for malignant lymphoma: a case report and literature review

Cyclophosphamide is considered to be a bladder carcinogen and there are many reports of secondary bladder cancer, while only a few cases of upper urothelial cancer have been described. A 59-year-old man, who had received cyclophosphamide therapy for malignant lymphoma, was suffering from gross hematuria and consulted our institute. Computerized tomography (CT), intravenous pyelography (IVP) and retrograde pyelography (RP) revealed a left renal pelvic tumor. Urinary cytology showed class V and radical left nephroureterectomy was performed. Histopathological diagnosis of the left renal pelvic tumor was transitional cell carcinoma, invading the renal parenchyma. He is free from recurrence eight months after surgery. To our knowledge, this is the third case of cyclophosphamide-induced upper urothelial carcinoma reported in Japan, and the twelfth reported in the English literature.

Case report of primary carcinoma in situ in upper urinary tract and review of the Japanese literature

A case of carcinoma in situ (CIS) in the right renal pelvis in a 71-year-old women is reported. The patient was admitted because of macroscopic hematuria. Drip infusion pyelography showed a filling defect (coagulum) in the right renal pelvis. Other abnormal findings were not made. Malignancy was suspected by cytology examination in both voiding urine and that obtained by catheter from the right pelvis. A right total nephroureterectomy was performed. Macroscopic abnormal findings were only of the coagulum in the renal pelvis. Pathologic examination showed CIS in the renal pelvis. We studied the features, pattern of recurrence, and prognosis of 19 cases of primary CIS in the upper urinary tract in the Japanese literature. A slight higher frequency was reported for women than for men. When the CIS was in the ureter, abnormal roentgenological findings, such as stenosis, filling defects, or a dilated ureter, were common (77%), contrary to expectation. But when the CIS was in the pelvis, such findings were rare. Urine cytology examination was positive in 95% of the patients. In four of the 19 patients, a recurrence was found. In all four patients, the first recurrence was in the bladder within 2 years of surgery. The kind of recurrent bladder tumors varied with the patients. The prognosis with recurrence was poor. If signs of recurrence were not recognized within 2 years of surgery, the prognosis was good.     

A clinical study of the renal pelvis and ureteral cancer

During the 13 years from 1976 to 1988, 160 patients with renal pelvic and ureteral cancer were reviewed based on a new general rule for clinical and pathological studies on renal pelvic and ureteral cancer of Japanese Urological Association. There were 71 renal pelvic cancers, 80 ureteral cancers, and 9 cancers in both regions. Patients ranged in age from 35 to 91 years old (average: 63). The involved side was right in 63 and left in 97. The most frequent symptom was hematuria, which was seen in 81.1%. IVP revealed the findings of filling defects, hydronephrosis, and non-visualized kidney in 99.7% of the patients. Total nephroureterectomy with bladder cuff resection was performed in 123 cases, nephroureterectomy in 16 cases, nephrectomy in 5 cases, partial ureterectomy in 10 case, and biopsy in 6 cases. As adjuvant therapies, irradiation was performed in 32 and chemotherapy in 123. Histologically, 156 were with transitional cell carcinoma, one squamous cell carcinoma, one adenocarcinoma and 2 unclear, the over-all survival rate of this study at 1, 3, 5 and 10 years were 86.8%, 73.0%, 65.3% and 45.6%, respectively. No patient with lymph-node metastasis (N+) survived longer than 5 years. All patients with M(1) died within one year. There were no difference of prognosis between renal pelvic cancer and ureteral cancer. Regarding various prognostic factors, our series gave the same results as previous reports. However, it should be stressed that pathological grading was the most important prognostic factor.     

A clinical study of tumor of the renal pelvis and ureter

We report 54 patients with urothelial tumors in upper urinary tract admitted to our hospital between July, 1962 and December, 1985. The patients consisted of 38 males and 16 females; side their ages ranged from 47 to 88 years with a mean of 63.4 years. The affected side was the right side in 21 cases, and the left side in 33 cases. Macro-or microhematuria was observed in 87% of the patients. Pathologically, 53 of the patients had transitional cell carcinoma and 1 had papilloma. Six patients had a past history of bladder tumor. Simultaneous bladder tumor was identified in 10 cases. Vesical recurrence was observed in 5 cases. Total nephroureterectomy with bladder cuff resection was employed as the surgical method in 21 cases, and total nephrectomy without bladder cuff resection in 11 patients. The actual five-year survival rate was 53% for all the patients; 52% for patients with renal pelvic tumors, 75% for those with ureteral tumors and 15% for those with renal pelvic and ureteral tumors. The patients who received nephroureterectomy had a postoperative survival rate similar to that of those who received nephroureterectomy with bladder cuff resection. A simultaneous bladder tumor lowered the survival rate.
