Current daily use of artificial sweeteners (AS) and diet drinks was evaluated for 1,862 patients hospitalized for cancer and for 10,874 "control" patients hospitalized for other conditions believed not to be associated with use of these substances. The data were derived from an ongoing survey in seven countries. For cancer of most sites, the age-standardized proportion of users of AS was somewhat less than that for controls. A greater proportion of users among cancer patients than among controls was noted only for cancer of the stomach among women. Little information on urinary tract cancer was available; there were no users of AS among 13 patients with cancer of the bladder, 5 with cancer of the renal pelvis, and 2 with cancer of the ureter. There were 455 cancer patients known to have been interviewed during their initial hospitalization for the disease. Based on these cases, an age-sex-country-standardized estimate of cancer incidence for users of AS, relative to nonusers, was 1.0. Only a very small proportion of patients reported daily use of diet drinks, and the proportion of users did not differ substantially between cancer patients and controls. The present data provide virtually no support for an overall positive association of AS with cancer.

A patient with transplanted kidney and immunosuppression treatment has been treated because of a total necrosis of ureter by a replacement of a ureter with a pyeloileocystoplasty. A second patient with transplanted kidney and immunosuppression therapy has been given care to with total cystectomy and supravesical derivation of the urine by a ileal conduit of a solid cancer or urinary bladder. The good clinical results, five, respectively two years after the operation confirm that neither kidney transplantation nor immunosuppression therapy are counter indications to the use of small intestine plastics of the bladder of the ureter.

Multiple transitional cell tumours of the renal pelvis and proximal ureter of a solitary kidney were successfully managed by total ureterectomy, extracorporeal subtotal resection of the renal pelvis, autotransplantation, and calicovesicostomy. The method permits resection of a maximum of the uroepithelium of the upper urinary tract at the same time as it preserves available renal parenchyma. It also implies a new and exciting approach to the renal pelvis for endoscopic postoperative control and local treatment of the malignancy.

A 65-year-old woman had pancytopenia, splenomegaly, and an inaspirable bone marrow. Diagnostic evaluation demonstrated that she had both leukemic reticuloendotheliosis (LRE), or hairy cell leukemia, and an additional lympho-reticular neoplasm, most likely a "histiocytic" lymphoma. The diagnosis of LRE was based on the histopathology of spleen tissue and of a bone marrow biopsy specimen. The diagnosis of diffuse "histiocytic" lymphoma was based on the histopathology of a splenic hilar and a mesenteric lymph node, tumor nodules in the kidney and spleen, and tissue from a mass obstructing a ureter. This is the first well-documented association of a second lympho-reticular neoplasm with LRE. Even relatively gently treatment of the "histiocytic" lymphoma resulted in fatal pancytopenia, illustrating the restricitons on therapy imposed by the marrow impairment due to the LRE.

It is now widely accepted that debulking operative resections can provide effective palliation for some patients with advanced pelvic malignancy, particularly with those malignancies originating in the ovary. Some of these radical operations require the resection of long segments of the ureter and portions of the bladder. Although there is a variety of techniques that can be used in this situation to restore the continuity of the urinary tract, in some instances a simple ureteral ligation may represent the best method of managing the "short ureter." In our experience with 23 patients who underwent intentional ureteral ligation, the procedure was found to be safe, expeditious, and beneficial in managing some of the complex problems associated with advanced pelvic malignant disease.

A comparison of the prognosis between 2 series of patients with urothelial renal pelvic tumors is presented. One series comprising 70 patients was operated with intrafascial nephrectomy with extirpation of varying length of the ureter. The other series comprising 38 patients was operated with transabdominal perifascial nephrectomy with homolateral adrenalectomy, total ureterectomy and in 28 patients retroperitoneal lymphadenectomy. The 5-year survival was 51% in the patients operated with intrafascial nephrectomy and 84% in the patients operated with perifascial nephrectomy. The difference in prognosis is statistically significant (p less than or equal to 0.01) and cannot be explained by differences in extent of tumor infiltration, tumor grade or tumor size. The main difference in prognosis between the two series was in patients with high stage tumors (Grabstald stage 3 and 4). The 5-year survival was 74% in patients with stage 3 and 4 tumors in the patients operated with perifascial nephrectomy compared with 37% in the patients operated with intrafascial nephrectomy. Since it is not possible with absolute certainty to determine tumor stage before the operation, an aggressive attitude against urothelial renal pelvic tumors is recommended. Thus the patients should undergo transabdominal perifascial nephroureterectomy including a cuff of the bladder wall and homolateral adrenalectomy. In patient with bilateral tumors, renal insufficiency of tumor in a single kidney parenchyma saving partial resection must be performed.

A survey is presented, based upon a personal material of 225 cases of urinary fistulae. 173 of them were postoperative or obstetric fistulae, whereas 52 had appeared after a radiological or combined radiological and surgical treatment for cancer of the uterus. --The author's method for preparing the fistula region from a transverse incision under the external urethral orifice is described as well as his grafting techniques. Vessels are brought to the fistula region by using flaps from one or both pubococcygeus muscles, the rectus abdominis muscle or the gracilis muscle. --For vesico-vaginal fistulae situated high up in the fundus a graft from the omentum majus or an appendix epiploica is sometimes used. They can usually be grasped from below after the peritoneum has been opened. --In cases where the ureters were also damaged by irradiation a special technique was used. After the damaged part of the ureter had been resected the ureters were implanted into an ileum segment which was anastomosed to the bladder fistula. --In one of the 173 non-irradiated cases, a Bricker-bladder had finally to be made because of the failure to achieve a functioning urethra. The others were all cured after one or in a few cases two operations. --Among the 52 cases, which had been irradiated, 46 coud to be made, one got a fast growing local recurrence of the carcinoma and one had too bad general condition to allow a diversion operation. Two patients have rest fistulae but may be possible to cure conservatively.

Replacement of ureter with a segment of ileum was successfully performed in two patients. One had ureteral cancer and the other recurrent calculi due to cystinuria. The first patient had only one kidney. In the second both ureters were replaced with ileum. Formation of a papilla at the distal end of the ileal segment in the bladder may reduce the risk of vesico-ileal reflux.

Percutaneous nephrostomy was performed in 32 patients: in 8 patients for permanent and in 24 for temporary drainage. The most common indication was obstruction of the distal ureter due to malignancy. Puncture of the renal pelvis was performed with the aid of fluoroscopy and/or ultrasound. Change to larger catheters was achieved using the Seldinger technique. Complications in the form of bleeding occurred in 5 patients and were in conjunction with repuncture after the initial catheter had slipped out, or occured in connection with change to larger catheters. With the routine use of ultrasound and specially designed catheters the method should be an effective alternative to operative nephrostomy also in the nonemergency patient.

A 61-year old woman with 7 years' history of pain, infections and haematuria developed right ureter stenosis which was suspected of being a tumour. Microscopic examination of the ureter with stenosis showed primary amyloidosis. Although primary amyloidosis of the ureter is rare, it should be included in the differential diagnosis of ureter malignancy.
