The presence of bacteria at the renal pelvis and the methods of their detection were studied in 11 patients with catheter-free cutaneous ureterostomy (tubeless ureterocutaneostomy). These patients had had total radical cystectomy due to bladder carcinoma. Of these, 5 patients had single-sided stoma with 9 kidney-ureter units and 6 patients had bilateral stoma with 10 units, excluding 2 ureters because of indwelling catheters. The urine obtained both from the renal pelvis with a single lumen catheter and from the pouch were used in the bacterial culture test and urinalysis. The aseptic swab after touching the skin around the stoma was also cultured for bacteria. Of 19 kidney-ureter units, 9 (47%) were found to have bacteria in urine obtained from catheterization. However, only 2 units (11%) were observed to be accompanied with pyuria. In this method, the rate of bacterial appearance was higher in single-sided stomas than in bilateral ones. There was no statistical correlation between the presence of hydronephrosis and the rate of bacterial appearance. In conclusion, the method of single lumen catheterization might be of great use for analysis of urinary tract infections in patients with such conditions.

Five cases (3M, 2F) of ureteral transitional cell carcinoma are reported. they have been observed in the last two years in a general surgical service. All the patients have been treated surgically. Gross hematuria was present in all the patients. Three cases had multicentric tumor sites. Three tumors were located in the distal ureter. Four cases showed a non functioning kidney at IVP. In two, because of obstruction, retrograde pyelography was unsuccessful. Ultrasound was able to demonstrate hydronephrosis. In the two cases submitted to angio-CT the spread of the tumor was correctly diagnosed. Frequency, etiology, clinical, diagnostic findings and surgical therapy as well have all been taken into account, based on the literature. Histopathologic aspects, grade and stage, are considered too. The authors emphasize the necessity to find and understand the cause of an unexplained hematuria, since ureteral carcinoma is not as rare as previously thought. Being grade and stage closely related to prognosis, the diagnostic delay must be reduced.

The use of a collagen sponge tube graft as a material for segmental ureteral replacement was investigated. The structural design of the collagen sponge graft was achieved by cell culture on the matrix. MGH-U1 cells, derived from bladder cell carcinoma, were grown in vitro on the collagen sponge matrix with excellent biocompatibility and without evidence of cytotoxicity. The collagen sponge demonstrated biodegradability when implanted subcutaneously in dogs. However, a urine exposure test of collagen sponge in rat bladders revealed extensive salt deposits on its surface in some rats, as observed by crystallographic examination. Segmental ureteral replacements by collagen sponge tube grafts, accompanied by ureteral splint catheters, were performed in dogs. There was extensive uro-epithelial cell regeneration on the inner surface of the collagen grafts, without evidence of severe hydronephrosis, 5 to 12 weeks following the procedure. The results indicate the potential for ureteral replacement by collagen sponge tube grafts, which would act as non-toxic, biodegradable scaffolds inducing the regenerative activity of the ureter.

Wertheim radical hysterectomy combined with pelvic lymphadenectomy was performed at the Helsinki University Central Hospital on 132 women of whom 120 had cervical carcinoma from Stage IA to early IIB and 12 had endometrial carcinoma Stage II. None of the patients died or had severe complications during their hospitalisation. The left ureter was accidently transected in two patients and both were corrected immediately. Wound complications occurred in 16 patients (12%). The high incidence of wound complications is probably partly related to the low-dose heparin prophylaxis. The initial clinical staging was found to be correct in 85% of the cases. Five cases were under-staged. All ten patients cases of early Stage IIB were over-staged, none of whom had parametrial invasion. The predictive value of lymphangiography was low, 14% in histologically positive cases and 89% in negative cases of lymph node metastases. Lymphangiography proved to be only of value in facilitating complete lymph node dissection. Intra-operative lymphangiographic control revealed radio-positive nodes and lead to further dissection in 30 patients (24%).

Two rat tumor cell lines which differ significantly in radiosensitivity, a rhabdomyosarcoma (R-1) and a ureter carcinoma (RUC-2), were treated with multiple fractions per day and low-dose-rate gamma radiation. The purpose of these experiments was to investigate (i) the influence of fraction size and interfraction interval on repair of sublethal damage (SD) and (ii) whether low-dose-rate irradiation can be simulated by giving multiple fractions per day which might be applied in clinical treatments. In both cell lines, multiple doses were given at 1- to 4-hr intervals. SD repair was at a maximum in 2 hr but did not reach the theoretically expected level. For both cell lines, survival at higher total doses was different from that theoretically expected if repair of SD was assumed to be completed and at the maximum level. To account for the observation that less than complete repair of SD occurred, theoretical survival curves were calculated with the assumption of a constant but less than 100% level of SD repair. Experimental data correlated well with these calculated curves. There were only very small differences in survival after the different multiple fractions per day regimens. Survival after irradiation at a dose rate of 1.00 Gy/hr was found to be similar to that after multiple fractions per day.

Concurrent primary renoparenchymal or renal pelvic neoplasms of different histology in the same kidney appear to be unusual. We herein report on a 75-year-old man in whom a tiny renal adenoma, a transitional cell carcinoma of the renal pelvis, ipsilateral ureter papillomas and transitional carcinoma of the urinary bladder were found. The clinicopathologic findings of this patient as well as the oncogenesis of renal tumours are discussed.

Closure of the ureter with a mixture of butyl-2-cyano-acrylate and lipiodol was performed for the palliative management of urinary incontinence in 4 patients (unilaterally in 3, bilaterally in 1), after urinary diversion had been provided by operative or percutaneous nephrostomy (inoperable vesico-(recto-)vaginal fistulas [2 patients] due to irradiated cervical carcinomas, contracted bladder due to irradiation [1 patient] and irradiated locally advanced prostatic carcinoma [1 patient]). In the first two patients the ureters were occluded by transurethral access using ureteral catheters followed in one case by dislocation of embolic material in the renal pelvis (without sequelae). The transrenal access for ureteral closure was employed in the two other patients using adjuvant balloon catheter occlusion. With this technique no complications were encountered. All patients were discharged free of complaints and completely dry. To achieve this result two patients had required a second ureteral embolisation.

A screening test for detecting antibodies to HSV-TAA was performed on 26 sera, from urinary bladder carcinoma patients and on 30 sera from prostatic carcinoma patients. Positive results were found in 50% of the urinary bladder cancer sera and in 60% of the prostatic carcinoma sera. As control 10/11 sera from benign prostatic hypertrophy and 4/4 sera from renal pelvis or ureter neoplasias (tumors never previously associated to HSV) were negative before and after surgery. The only one positive of the former group became negative after surgical treatment. The TAF-test can therefore be a meaningful test for monitoring antibody levels in the sera of patients before, during or after the treatment, in order to evaluate the presence of metastases or the success of a therapy.

Metastatic carcinoma to the testis is unusual. There are only seven previously reported cases in which a testicular mass was the first clinical manifestation of an underlying malignancy. The authors review 127 cases in which the testis was involved by metastatic carcinoma, and describe an additional two patients in whom a malignant testicular mass was the presenting sign of an underlying nontesticular carcinoma. The tumors most commonly reported to metastasize to the testis are: prostate (45 cases), lung (25 cases), melanoma (12 cases), colon (11 cases), kidney (10 cases), stomach (6 cases), and pancreas (5 cases). Neuroblastoma, retinoblastoma, carcinoid tumor, and cancers of the bile duct, ureter, bladder, salivary gland, and thyroid have also involved the testis secondarily. Nineteen patients (15%) had bilateral testicular metastases. Patients with secondary testicular neoplasms were older in general than those with germ cell tumors (mean, 55 years; median, 57 years). Histologically, the presence of extensive lymphatic and vascular invasion and an interstitial pattern, in which the seminiferous tubules are spared, is suggestive of a metastasis. In four of the nine cases (44%) in which testicular enlargement was the first manifestation of an underlying carcinoma the correct pathologic diagnosis was initially missed. Serum alpha-fetoprotein (AFP) and human chorionic gonadotropin (HCG) are occasionally elevated in patients with nontesticular primary tumors, but markedly elevated levels in young patients suggest a nonseminomatous germ cell tumor, as does positive immunoperoxidase staining for AFP and HCG.

This report presents a case of pelvic actinomycotic infection that was accurately diagnosed preoperatively by means of fine needle aspiration. The patient was a 40-year-old black female, gravida 6, para 6, who presented to the emergency room complaining of intermittent, crampy lower abdominal pain of approximately 1 month's duration. She also complained of a recent onset of urinary frequency and urgency without dysuria as well as a change in bowel habits, with recent constipation. Review of the patient's medical history was notable for the placement of a Dalkon Shield IUD 10 years before without subsequent removal, a history of irregular menses in the past year, and treatment for gonorrhea 10 years previously. The patient's last menstrual period was 2 weeks prior to admission. She denied fever and night sweats but had lost 20 pounds in the past 2-3 months. Vital signs were normal. Pelvic examination revealed a firm, fixed uterus, approximately the size of a 14-week pregnancy, and an associated mass extending to the left and inferiorly into the rectovaginal septum. An intravenous pyelogram showed left hydronephrosis and hydroureter, with compression of the ureter at the level of the sacrum. Sigmoidoscopy revealed extrinsic compression of the rectum at 12 cm, the some mucosal edema. A CT scan of the pelvis disclosed an 8 cm mass in continuity with the uterus extending into the lower pelvis, with possible focal erosion of the sacrum. The clinical impression was advanced cervical carcinoma. Transvaginal fine needle aspiration was performed using a 21-gauge spinal needle and a Franzen needle guide. Following a diagnosis of actinomycotic abscess, the patient was placed on tetracycline, due to her penicillin allergy, and taken to surgery. The abdomen was opened and revealed a slightly enlarged uterus. The uterus and cervix were adherent to the left pelvic wall and posteriorly to the rectum by firm, friable tissue. The left fallopian tube and ovary were adherent to this . With some difficulty the uterus was freed, and a total hysterectomy and bilateral salpingo-oophorectomy were performed. The postoperative course was unremarkable, and the patient was discharged on tetracycline. A morphologic diagnosis of actinomycotic infection with abscess formation was made. Sections of the left parametrium revealed multiple microabscesses and sinus tracts surrounded by abundant granulation tissue. Some of the abscesses contained actinomycotic organisms. Chronic endometritis and cervicitis as well as acute and chronic left salpingitis were documented.
