We report 82 patients with renal pelvic and ureteral tumors admitted to Kyoto Prefectural University of Medicine, Kyoto Second Red Cross Hospital and Shakai-Hoken Kyoto Hospital between January, 1981 and December, 1991. Sixty two were males and 24 were females, and they were between 47 and 93 years old (average: 68.2 years). The tumor occurred on the right side in 34 patients, on the left side in 51 patients and on both sides in one patient. There were 43 renal pelvic tumors, 37 ureteral tumors and 6 renal pelvic with ureteral tumors. The most frequent symptom was macrohematuria, which was seen in 54 patients (62.8%). Urinary cytology was performed in 76 patients and a positive result was obtained in 44 patients (57.9%). We performed surgical treatment on 71 patients. The most frequently adopted method was total nephroureterectomy with partial cystectomy which was performed on 51 patients (71.8%). Of the 73 specimens diagnosed histopathologically, 71 specimens were transitional cell carcinoma (TCC), one was a squamous cell carcinoma (SCC) and one was a mixed type of TCC and adenocarcinoma. As to grading, 6 specimens were G1, 28 G2, 38 G3 and one GX. As to staging, 8 specimens were pTa, 17 pT1, 21 pT2, 18 pT3, 8 pT4 and one pTX. The overall survival rate (by Kaplan-Meier's method) at 3 and 5 years was 47.0% and 39.5%, respectively. The patients with high grade tumors and those who had ureter preservation, the survival rate was lower than in the other patients.

A 60-year-old male with a small cell carcinoma of the right lower ureter is presented. The tumor mainly comprised a small cell carcinoma but also included a full variety of histological types such as transitional cell carcinoma, squamous cell carcinoma, adenocarcinoma, leiomyosarcoma and chondrosarcoma. Immunohistochemical staining was positive for neuron specific enolase and cluster 1 small cell lung cancer antigen/N-CAM in the small cell carcinoma and S-100 in the chondrosarcoma component. The patient underwent a right nephroureterectomy, and received prophylactic radiation of the pelvic and para-aortic lymph node regions and cisplatin and etoposide combination chemotherapy. Eight months after the chemotherapy, a transitional cell carcinoma was found in the bladder neck, and a cystectomy with urethrectomy performed. To our knowledge, this is the second report of a small cell carcinoma originating from the ureter.

We report 59 patients who were considered candidates for laparoscopically assisted surgical staging (LASS) to manage their clinical stage I adenocarcinoma of the endometrium. Their ages ranged from 40 to 85 years, with a mean of 69; their weights ranged from 102 to 267 pounds, with a mean of 153 pounds. Patients with intraperitoneal disease were taken off study. Laparoscopic pelvic and para-aortic lymphadenectomies were performed based on the grade of the tumor and the depth of myometrial invasion. Six patients were discovered to have intraperitoneal disease. Of the remaining 53 patients, 29 underwent lymphadenectomy, 1 of whom had positive para-aortic nodes. Of the 24 patients who did not have laparoscopic lymphadenectomy, 2 should have, according to the study criteria; however, obesity precluded this from being performed. Eight patients had grade 3 lesions; of these, 4 lesions had metastasized. The remaining 3 patients with metastatic disease had grade 2 lesions. Complications were related to the laparoscopically assisted vaginal hysterectomy and resulted in two laparotomies: one for a transected ureter and the other for a cystotomy. Estimated blood loss was < 200 cc and the average hospital stay was 2.9 days. We feel that LASS is an attractive alternative to the traditional surgical approach in patients with stage I endometrial carcinoma.

Fifty eight cases of primary tumors in the renal pelvis and ureter were treated at Toranomon Hospital between 1983 and 1992. They consisted of 32 renal pelvic tumors, 21 ureteral tumors and 5 tumors at both sites. The age of the patients ranged from 30 to 84 years (mean 63.1). Surgery was performed in 56 cases. Radical nephroureterectomy with concomitant ipsilateral retroperitoneal lymph node dissection was performed in 38 cases. The other surgeries were radical nephroureterectomy without lymph node dissection in 9, nephrectomy in 4, resection of ureter and reanastomosis in 3, radical nephroureterectomy and cystectomy in 1 and partial nephrectomy in 1. Pathologically, 53 were transitional cell carcinoma (TCC), 2 were TCC plus squamous cell carcinoma and 1 was TCC plus adenocarcinoma. Over-all survival rates (Kaplan-Meier) of 56 surgical cases at 1, 3, 5 years were 92.2, 83.7 and 72.8%, respectively. Combination chemotherapy (M-VAC or CAP) was performed in 9 cases of metastatic disease and 1 case of bilateral disease. Of these 10 cases, one achieved complete remission, 2 no change and 7 had progressive disease. Adjuvant chemotherapy was performed in 21 cases after surgery. These 21 patients were of high risk in recurrence either Grade 3 or pT3. However, the 5-year survival rate was 77.3% in these patients. Thus we conclude that the adjuvant chemotherapy in high risk patients was effective in our cases.

We report the case of a 66-year-old woman with a bleeding adenocarcinoma of the lower thirty of the rectum. The laparoscopic procedure was initiated with mobilization of the sigmoid colon. The left ureter was identified as it crosses the left iliac vessels. The peritoneum along the right side of the rectosigmoid mesentery was transected. The superior rectal artery was divided utilizing extracorporeal ligatures. The anterior rectum was separated from the uterus, the pararectal tissue was mobilized, the middle rectal arteries were ligated and the posterior rectum was dissected from the presacral tissue. The perineal component of the procedure was simultaneously performed. The sigmoid loop was extracorporeally transected with a linear stapler. The proximal sigmoid end was exteriorized through the colostomy site (site of the left superior port). The distal sigmoid end was replaced in the abdominal cavity and was grasped through the perineal wound; the anus, rectum and sigmoid were removed through the perineal wound. The feasibility of this procedure has been well established. However, it seems to be an alternative for the classical abdominoperineal resection as treatment for adenocarcinoma of the lower rectum. His superiority has yet to be confirmed by future studies.

We report a rare case of primary adenocarcinoma of the renal pelvis and ureter in an incomplete duplicated ureter. A 69-year-old male with macroscopic hematuria consulted our hospital. Retrograde pyelography revealed left incomplete duplicated ureter and a filling defect in the lower pole of the ureter. Transurethral ureteroscopy was employed to investigate the filling defect, and a papillary tumor was detected extending into the lower segment of the incomplete duplicated ureter. From these findings, the patient was diagnosed with tumor of renal pelvis and ureter, and left total nephroureterectomy was performed. Pathological diagnosis was adenocarcinoma of the renal pelvis and ureter, INF beta, pT2, pR0, pL0, PV0, PN0. No evidence of either tumor recurrence or metastasis was found on the 3-month postoperative follow up. This case is thought to be the first report of primary adenocarcinoma of the renal pelvis in an incomplete duplicated ureter.

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.

A middle-aged man with a history of Hodgkin's disease presented with loin pain and microscopic hematuria. Radiologic studies demonstrated a urinoma secondary to ureteric obstruction at the pelvic brim. Percutaneous nephrostomy was performed to decompress the collection and a ureteric stent inserted to maintain drainage. Laparotomy revealed an unsuspected rectal adenocarcinoma. A metastatic deposit compressing the ureter had produced the urinoma. Metastatic colorectal carcinoma is a rare cause of urinoma.
