Two cases of papillary carcinoma of the bladder are presented in which the ureter could not be demonstrated by standard radiographic techniques. Computed tomography (CT) allowed identification of the tumor filled ureter. Intraureteral papillary tumor has a radiographic density (CT number) above that of water but less than that of the enveloping ureter.

The relative incidence and intensity of oviposition in schistosomiasis in different layers of both the urinary bladder and the ureter are presented. Histopathological changes in both organs are elucidated. Oviposition was heaviest in the submucosa of the urinary bladder, while the muscle layer was affected in 15% of specimens. Oviposition was mainly periureteral and in outer muscle layer of the ureter, and was present in only 22% in the ureteral submucosa. Epithelial changes, namely, Brunn nests, cystitis glandularis, cystitis cystica, and squamous metaplasia, were more marked in the bladder specimens than in the ureteral specimens. Squamous cell papilloma and squamous metaplasia associated with acanthosis of the bladder specimens were identified. Results indicate unanimously that the heavy deposition of ova in the submucosa of the bladder leads through its mechanical and toxic irritation to marked epithelial and premalignant changes which pave the way for the disturbing frequency of carcinoma of the bladder in the bilharzial patients which is not the case in the ureter.

From March 1982 through July 1988, 76 men underwent nerve-sparing radical cystoprostatectomy for carcinoma of the bladder at our hospital. Of the 76 patients 2 (2.6%) had positive surgical margins (dome of the bladder and left ureter) and neither had positive margins at the site of nerve-sparing modifications. Of 3 patients (3.9%) who had local recurrence none had positive surgical margins. The 5-year actuarial local recurrence rate is 7.5%. Thirteen of 76 patients (17%) died of transitional cell carcinoma and 7 (9%) died of other causes, while 53 (70%) are alive without evidence of disease with a mean followup of 38.4 months. The 5-year actuarial survival rates are 64% over-all, 68% without disease and 78% disease-specific. Of the 42 evaluable men who underwent cystoprostatectomy alone 27 (64%) are potent, compared to 2 of the 12 men (17%) who also underwent urethrectomy. We conclude that the nerve-sparing modifications do not compromise cancer control, that local recurrence and survival rates are at least comparable to those achieved with standard radical cystoprostatectomy, and that it is possible to preserve potency in most men undergoing this procedure.

The commonest urologic complication in 176 cases of chronic urinary bilharziasis was ureteric stricture (87 ureters in 55 patients), with the lower third of the ureter affected in 87% of the cases. Other complications included squamous-cell carcinoma of the bladder, urinary calculi and bladder calcification. Intravenous urography and cystoscopy were the most useful diagnostic methods in 76% of the cases. Post-micturition erect urography and frusemide intravenous urography gave great help in distinguishing between true mechanical and non-mechanical ureteric obstruction in patients with dilated pelvicalyceal system on conventional urograms. Only 17 of 68 dilated ureters were truly obstructed and required excision and ureteroneocystostomy. Postoperative vesicoureteric reflux developed in four of these cases. No deterioration of renal function occurred in the remaining, conservatively treated patients.

A prospective randomized trial compared cisplatin alone versus cisplatin, doxorubicin and cyclophosphamide in the treatment of advanced carcinoma of the bladder, ureter and renal pelvis. Objective responses were noted in 7 of 45 patients (16 per cent) given cisplatin alone and in 9 of 42 (21 per cent) treated with the combination. There was no significant difference in response rate, response duration or survival but the combination was more toxic. Other combination regimens should be evaluated.

In 300 urological patients with long-term intake of phenacetin-containing compounds, renal (papillary necrosis, chronic interstitial nephritis) and extrarenal manifestations appeared after an average latency period of 20 years. Course and prognosis primarily depend on the successful cessation of analgesics and the elimination of the accompanying infection. In the last decade, an increase of transitional cell carcinoma induced by analgesics has been observed. 31 of our patients presented a tumor of the urothelium (i.e. 10.3%) 26 patients presented isolated carcinoma of the bladder, 2 persons were diagnosed as having cancer of the bladder and the renal pelvis, and 1 patient had cancer of the bladder and the ureter. Only 2 persons suffered from isolated carcinoma of the renal pelvis. A further increase of these specific cases if expected.

971 samples of urine and washes of the urinary bladder in 643 patients were investigated cytologically. Urothelial carcinoma was present in 27 patients. In 11 cases the carcinoma was diagnosed by urinary cytology; 7 of the carcinomas were localized in the urinary bladder, 3 in the renal pelvis and 1 in the ureter. By contrast, all 19 tumors diagnosed in washes were localized in the urinary bladder. Diagnostic sensitivity was 100% in urine and about 75% in bladder washes. In 5 other patients cytologic diagnosis of carcinoma could not be confirmed by histology. In 4 of these, urothelial papillomas were present and in 1 patient a carcinoma of the bladder had been resected previously. Thus, the diagnostic accuracy of urinary cytology is good if essential methodological prerequisites are fulfilled. Therefore, urinary cytology appears to be an appropriate method for screening programmes in high risk patients such as phenacetin abusers. The estimated costs of a screening programme in Basel are 50 000-150 000 Swiss francs. However, a preliminary study to verify the value of such a screening programme is suggested.

A case of adenomatous polyp occurring at a ureterocaecal anastomosis, 25 years after urinary diversion following a total cystectomy for carcinoma of the bladder, is reported. Bilateral nephrectomy for chronic pyelonephritis was carried out 25 years after the initial surgery and, following this, a sinus formed at the incision at the right loin. A sinogram showed contrast filling the right ureter and caecum, and outlined a lobulated filling defect at the ureterocaecal anastomosis. Subsequent histology revealed a dysplastic tubulovillous adenoma. The clinical presentation and management of tumours at the ureterointestinal junction are discussed.

Described report case of the patient after left nephrectomy, performed 18 years ago, for adenocarcinoma. Recently he has a simultaneous carcinoma of the bladder and the left ureter. Carcinoma of the bladder was treated with transurethral resection and electrocoagulation. Once checked, the hemorrhage was found from the left ureter, later, papilocarcinoma was diagnosed and the urethrectomy with the resection of the part of the wall of the bladder in the region of the estuary. Patient was in good condition 5 months after the operation. There is a review of others report cases.

A 45-year-old man with a history of cyclophosphamide exposure underwent repeated ureteroscopy for positive urine cytology findings after resection of a Grade 2 papillary transitional-cell carcinoma of the bladder. Despite careful technique, an intussusception developed in the left ureter, which was repaired by resection and construction of a Boari flap. To our knowledge, this is the first report of retrograde ureteral intussusception caused by ureteroscopy.
