A case of solitary metastasis to residual ureter from renal cell carcinoma is reported. In November, 1987, a 56-year-old male had undergone left radical nephrectomy with renal cell carcinoma (clear cell subtype, G2, Inf alpha). He was doing well until June in 1989 when macroscopic hematuria occurred. A tumor from residual ureter with a large blood clot was detected on cystoscopy. A malignant tumor from the residual ureter was suspected and it was extirpated. Histological diagnosis revealed the same findings as the primary renal tumor. No other metastasis was detected. Only 8 cases of ureteral metastasis from renal cell carcinoma after radical nephrectomy have been previously reported in the Japanese literature.

Three patients (1 man, 81 years old; 2 women, 56 and 61 years old) had renal cell cancer and transitional cell cancer in the same kidney, and another patient (female, 77 years old) had renal cell cancer and transitional cell cancer in the ipsilateral ureter. Simultaneous occurrence of renal cell cancer and transitional cell cancer is an extremely rare entity with only 15 cases having been reported.

A 49-year-old male with left renal cell carcinoma and urothelial cancer (bladder and residual left ureter), which asynchronously occurred, was reported. He had received radical nephrectomy due to renal cell carcinoma 12 years earlier. He was followed up by his local physician for 7 years postoperatively, during which time no metastatic lesion was detected. However, he presented with macroscopic hematuria on January 7, 1992, and a diagnosis of urinary bladder cancer was made at our hospital. Computerized tomography demonstrated a non-papillary, broad-based tumor on the left wall of the urinary bladder, which histologically was transitional cell carcinoma (grade 3). Radical cystectomy, ureterectomy of the left residual ureter and ileal conduit were performed. Histological examinations showed that the urinary bladder tumor was transitional cell carcinoma, grade 3, pT-3b, and CIS (transitional cell carcinoma, grade 3) was found in the residual left ureter. Chemotherapy containing cis-platinum was performed as an adjuvant therapy, but multiple lung metastatic lesions appeared 2 months postoperatively, the histology of which was transitional cell carcinoma, suggesting metastasis from the urothelial cancer. Chemotherapy was ineffective, and he died of the disease 9 months after the operation. If this patient had been under long-term follow-up, the urothelial cancer may have been resected completely by transurethral resection. Our report indicated the importance of examination of the urinary tract in patients with such cancers, as well as the necessity of long-term follow-up.

In the traditional kidney position three trocars are inserted after creation of a pneumoperitoneum: 10 mm periumbilical (port I), 10/12 mm subcostal (port II) and 12/10 mm above the iliac spine (port III) in the mamillary line. After laterocolic incision the colon is dissected away from the lateral wall. Thereafter two 5-mm trocars (ports IV, V) are inserted into the lateral abdominal wall parallel to parts II and III. Following clipping and dissection of the ovarian (spermatic) vein, the ureter is isolated and incised. Then the cranial part of the ureter is used as a retractor exposing the renal hilum for dissection of the renal vessels. The main renal artery and vein are dissected separately by use of an endoscopic stapling device (Endo-GIA, white magazine). Finally, the kidney including Gerota's fascia is isolated from the adrenal and the upper peritoneum. Entrapment of the organ is performed with a specially designed bag (Lap-sac). The neck of the bag is brought out onto the surface of the abdomen (via port II/III) allowing digital morcellation with index finger inside the bag and removal of the organ in several pieces. We have applied this technique for 17 procedures in the upper retroperitoneum: 9 transperitoneal laparoscopic nephrectomies (TLN) for benign disease (5 hydronephrosis, 3 renovascular disease, 1 chronic pyelonephritis), 3 radical TLN including adrenalectomy for renal cell carcinoma (T2G2), 1 adrenalectomy for a cortical adrenaloma, 1 nephroureterectomy, 1 diagnostic ureterolysis and 2 modified retroperitoneal lymphadenectomies for stage I testicular cancer. The mean operation time was 4 h (2-5), the mean postoperative hospital stay 6 days (4-12).(ABSTRACT TRUNCATED AT 250 WORDS)

Extremely rarely renal cell carcinoma metastasizes to the contralateral renal pelvis or ureter. The present report concerns a case where a metastatic tumor could be successfully removed from the left renal pelvis 3 years after right nephrectomy for the primary tumor. A review of the literature revealed this to be only the fourth such case documented.

Since July 1991, we have performed laparoscopic nephrectomy for removal of damaged kidneys in thirteen patients. In addition, we recently developed a new procedure of laparoscopic nephrectomy for renal cell carcinoma and successfully removed the kidney with renal cell carcinoma. Patients' age ranged from 18 to 80 years with the average being 50 years. There were 8 male and 6 female patients. Original disease was calculous disease in 5 patients, vesicoureteral reflux in 4, renovascular disease in 2, ureteropelvic junction obstruction in 1, ectopic ureter in 1 and renal cell carcinoma in 1. The mean size of the diseased kidney was 9 x 5 x 4 cm in the initial 13 cases and 13 x 7 x 6 cm in the case with renal cell carcinoma. The size of the tumor was 2.5 x 2 x 2 cm. In the first 13 patients, nephrectomy was performed as described previously. In the patient with renal cell carcinoma, a new procedure was applied. In the new procedure, five trocars were introduced into the abdominal cavity through the lateral abdominal wall. The kidney was removed en bloc together with the adrenal gland, perirenal fat and Gerota's fascia in the same fashion as traditional radical nephrectomy. Thirteen kidneys were successfully removed, but one failed because of dense adhesion to the surrounding tissue. Three of the 13 patients required additional laparotomies to control bleeding or to remove missed stone.(ABSTRACT TRUNCATED AT 250 WORDS)

Cathepsin B is a lysosomal cysteine proteinase which is thought to regulate intracellular protein metabolism. In the present study, cathepsin B-like activity was determined in the urine of 53 patients with renal cell carcinoma, 22 patients with urothelial carcinoma and 41 control subjects. In addition, immunohistochemical study of cathepsin B was performed in specimens obtained from 20 patients with renal cell carcinoma, 59 patients with bladder carcinoma and 20 patients with renal pelvic and ureter carcinoma by using sheep anti-human liver cathepsin B antibody. Cathepsin B-like activity was higher in the urine from patients with renal cell carcinoma or urothelial carcinoma than in that from controls. Positive reactions for cathepsin B were found in 18 of 20 patients with renal cell carcinoma, in 37 of the 59 patients with bladder carcinoma and in 14 of the 20 patients with renal pelvic and ureter carcinoma. In patients with urothelial carcinoma high rates of positive reaction for cathepsin B were observed in patients with advanced stage tumors, with INF gamma-type tumors and with metastatic lesions. In patients with renal cell carcinoma, there was no correlation between the rate of positive reaction and pathological findings. These results indicate that urinary cathepsin B-like activity is higher in patients with urological cancer and that a highly positive reaction for cathepsin B is a risk factor for tumor invasion, metastasis and poor prognosis in patients with urothelial carcinoma.

A case of ureteral metastasis from renal cell carcinoma is reported. A 71-year-old man who had received radical nephrectomy for left renal cell carcinoma, G1 and about two years earlier presented with asymptomatic macrohematuria. He had received interferon therapy and surgical treatments for bone metastasis two times after the operation. Cystoscopic examination revealed bleeding from the left residual ureter but CT scan showed no abnormal findings. Left ureterectomy and partial cystectomy was performed and a small finger tip-sized tumor was found at 13.5 cm above the ureteral orifice. Pathological examination showed metastatic renal cell carcinoma, G1 > G2. Histologically and clinically, this tumor seemed to have metastasized by a hematological pathway. Seventeen cases of ureteral metastasis of renal cell carcinoma have been reported previously in the Japanese literature.

An 81-year-old woman was admitted to our hospital with left flank pain. Excretory urography revealed left hydronephrosis. Abdominal computed tomography (CT) revealed a large heterogenous tumor in the upper pole and marked hydronephrosis and hydroureter in the lower portion of the left kidney. Left total nephroureterectomy was performed under the diagnosis of renal pelvic and ureter tumor. The pathological diagnosis was of renal cell carcinoma (spindle type, grade 3) in the kidney and transitional cell carcinoma (grade 2) in the ureter. Postoperative chemotherapy was not given. Convalescence was uneventful and fifteen months after the operation she is alive with no recurrence or metastasis.

Presentation of a case-control study on 755 subjects with the purpose of defining whether the development of a neoplasia on any organ and of any histological type, either synchronous or metachronous, occurs more frequently in patients who already have vesical carcinoma (338 cases) versus other populations of similar epidemiological characteristics comprising subjects who do not present that condition (417 controls). The evaluation of the difference between both groups establishes a cause-effect relationship expressed in terms of an odds ratio of 2:11 which allows to claim that presence of a second neoplasia is more frequent in patients with vesical carcinoma (p < 0.001). The paper also includes a discussion on the distribution to organs and systems. Once the cases with urothelial site (renal pelvis, ureter or urethra) are excluded, prostate adenocarcinoma is the most frequent form associated to vesical carcinoma, followed at a distance by renal adenocarcinoma, epidermoid carcinoma of the larynx and bronchopulmonary carcinoma. Cumulative incidence of secondary neoplasias, including tumours diagnosed synchronically is 12% at 54 months.
