Management of colovesical fistulae associated with pelvic malignancy.

Thirteen patients with malignant colovesical fistulae are presented. The underlying pathology was cancer of the colon (seven cases), bladder (four cases) and cervix (two cases). The series demonstrates that wide surgical excision may be needed to achieve tumour clearance and that this may necessitate pelvic exenteration. Three patients who underwent inadequate tumour excision developed recurrence in the bladder, two with a fatal outcome. Wide excision of the bladder may be performed without urinary diversion by subtotal cystectomy and a reconstructive procedure. Substitution cystoplasty was performed on two patients at the time of tumour excision. Urinary tract involvement by such tumours is often extensive and optimal results may be achieved with a multidisciplinary approach.

Comparison of mixed antiglobulin reaction and direct immunobead test for detection of sperm-bound antibodies in subfertile males.

OBJECTIVE: To compare two methods of detection of surface bound antibodies on spermatozoa from subfertile males. DESIGN: Prospective comparison of direct mixed antiglobulin reaction (MAR) for immunoglobulin (Ig)G with direct immunobead test (IgG and IgA) applied to spermatozoa from male partners of infertile couples. Circulating unbound antibody measured by tray agglutination test in serum and seminal plasma in a representative proportion. SETTING: Seminology laboratory. PATIENTS: One hundred nine male partners of infertile couples. RESULTS: Highly significant correlation between direct MAR (IgG) and direct immunobed test (IgG) and between both of these tests and serum unbound antibody measured by tray agglutination test. Highly significant correlation between direct immunobead test (IgA) and seminal plasma unbound antibody measured by tray agglutination test, but no correlation with MAR (IgG). CONCLUSIONS: Mixed antiglobulin reaction (IgG) is a cheap, quick, and sensitive screening test, but immunobead test (IgA) provides useful additional information on class of antibody on spermatozoa that may be clinically more important.

Müllerian duct (prostatic utricle) cyst: diagnosis and treatment in subfertile males.

Müllerian duct cysts causing ejaculatory duct obstruction were discovered in 26 subfertile males; 21 patients had either azoospermia or very severe oligozoospermia. Characteristic seminal findings were a small volume ejaculate with acid pH and little or no fructose. The lesions were demonstrated by vasography and treated by endoscopic incision. After surgery there was a distinct improvement in volume of the ejaculate and sperm concentration in 10 patients, although another 10 patients continued to have azoospermia or severe oligozoospermia due to either persisting obstruction or secondary epididymal blocks. Eight female partners became pregnant.

Urinary tract metastasis from renal carcinoma.

Five patients with urinary tract metastases from renal carcinoma are presented. In 4, urinary tract metastasis occurred in the absence of spread elsewhere. The initial presentation in 1 patient was ureteric obstruction; 3 others re-presented with haematuria and the fifth patient was diagnosed post mortem. Metastatic sites included ipsilateral ureter, contralateral ureter, ureteric stump, bladder and prostatic fossa. After previous nephrectomy for renal carcinoma, urinary metastases, although rare, should be considered and investigation of unexplained haematuria should include the ureteric stump. Useful palliation and possibly cure can be achieved by resection of these lesions.

Cystectomy and substitution enterocystoplasty: alternative primary treatment for T2/3 bladder cancer.

The optimal treatment for invasive bladder cancer remains controversial. Although external beam radiotherapy is able to eradicate the disease in a number of patients, the difficulty is selecting those who will respond. Those who do develop a local recurrence will require a salvage cystectomy combined with urinary diversion. The results of performing cystectomy and bladder reconstruction as a primary procedure are presented and the concept of combining this with chemotherapy as an alternative strategy for the management of bladder cancer is discussed.

Endometriosis of the ureter.

Five patients with ureteric endometriosis are described. Extensive pre-operative investigation failed to reveal the aetiology of the unilateral upper urinary tract obstruction seen in all of these patients. Due to the dense fibrosis that invariably accompanies ureteric endometriosis, early surgical excision of the ureteric stricture permits effective resolution of upper tract dilatation and improved renal salvage.

Endometrioid carcinoma of the prostate: a misnomer?

The origin of this unusual variant of carcinoma of the prostate has provoked discussion ever since its first description in 1967. This is of both embryological interest and therapeutic importance. Four cases have been reviewed, and all have demonstrated immunohistochemical features consistent with an origin from prostatic tissue. In addition, three had evidence of disseminated disease which responded well to androgen ablation. It is concluded that the term endometrioid carcinoma is of descriptive value only, and these tumours are a variant of primary duct prostatic carcinoma. Patients should be treated by androgen ablation when metastases are present.

Combination chemotherapy with bleomycin, etoposide and cisplatin (BEP) for metastatic testicular teratoma: long-term follow-up.

127 men with previously untreated non-seminomatous germ cell tumours (NSGCT) of the testis were given BEP chemotherapy (bleomycin, etoposide and cisplatin) between 1979-1986. Long-term follow-up (median 65 months) has shown an overall 5 year survival of 87.2% (95% confidence limits 81.1%-93.3%). Outcome was related to both tumour volume and serum marker levels of alpha-fetoprotein (alpha FP) and beta human chorionic gonadotropin (HCG), with 5 year actuarial survivals of 97.8%, 72.2% and 26.7% respectively for small, large and very large volume disease defined by Medical Research Council criteria, and 91.2% and 60.8%, respectively, for men with low (alpha FP less than or equal to 500 kU/l and HCG less than or equal to 1000 iU/l) or high serum marker levels. 79 men (62%) had a complete radiological and serum marker response to chemotherapy alone; residual masses postchemotheraphy were resected in 39 patients (31%), showing undifferentiated tumour in only 6 (15%). 23 of the 127 patients (18%) failed to respond or developed recurrent disease after BEP; only 5 were successfully salvaged. Myelotoxicity of treatment was mild with grade 4 toxicity in 2% of chemotherapy courses and 3 episodes of neutropenic sepsis. Mean glomerular filtration rates fell by 15.6% between courses 1 and 4 of BEP. Bleomycin pneumonitis developed in 13% of cases with 1 fatality. So far 21 men have had children following chemotherapy, but semen analysis 12 months or more (median 36 months) after treatment showed azoospermia in 11 out of 54 (20%) men tested. BEP chemotherapy can be regarded as standard treatment for patients with metastatic NSGCT in low-risk categories, but more intensive therapy is required for advanced presentations. Strategies to develop "risk related" treatment are under investigation.

Anterior pelvic reconstruction with ileum after cancer treatment.

Ileum has been used to reconstruct the lower urinary tract in 15 patients (10 women, five men) after treatment for bladder or gynaecological cancer. Seven patients had previously received radical pelvic irradiation. Four methods were used: group 1 (five patients): bladder patch after partial cystectomy or bladder augmentation after clam cystotomy for bladder contracture; group 2 (four patients): bladder replacement after subtotal (supratrigonal) cystectomy; group 3 (two patients): ureteric replacement for lower ureteric obstruction or fistula, and group 4 (four patients): complete replacement of bladder and lower ureters after anterior pelvic exenteration, with creation of neovagina from caecum in the two female patients. Review of the results indicates that ileum provides a versatile and safe material for anterior pelvic reconstruction in cancer patients even after previous pelvic irradiation.

Effectiveness of carboplatin, etoposide, and bleomycin combination chemotherapy in good-prognosis metastatic testicular nonseminomatous germ cell tumors.

The combination of carboplatin, etoposide, and bleomycin (CEB) was evaluated as initial chemotherapy in 76 patients with good-prognosis metastatic nonseminomatous germ cell tumors (NSGCT) between 1984 and 1988. The classification of eligible patients included Royal Marsden Hospital (RMH) stages IM, IIA, IIB, IIC, IIIA, IIIB, IV0ABCL1, and IV0ABL2. Four courses of combination chemotherapy were administered in a 21-day cycle, and surgical excision of residual mass was performed in 27 cases (23 laparotomies and four thoracotomies). At the time of analysis, median follow-up was 24 months from start of chemotherapy (range, 6 to 54 months). The 2-year cause-specific survival probability was 98.5%, the single cause-related mortality being caused by bleomycin pneumonitis. Five patients failed CEB chemotherapy, but all have been successfully salvaged with a combination of surgery and intensive chemotherapy, follow-up from completion of all treatment being 35 to 44 months. The toxicity of CEB included bone marrow suppression and alopecia in all patients but no significant neurotoxicity or ototoxicity, and minimal renal toxicity. Only four (5%) patients had a decrease in the glomerular filtration rate greater than 15%. In 51% of patients, the hemoglobin fell below 10 g/dL. The WBC count nadir was less than 1,500/microL in 11% of treatment cycles and in 16% the platelet nadir fell below 50,000/microL. Decreases in the WBC and platelet counts were of very brief duration. Only one of 310 CEB cycles was complicated by neutropenic sepsis, and there were no episodes of thrombocytopenic purpura or bleeding. We conclude that the CEB combination represents an effective alternative to cisplatin-based chemotherapy in good-prognosis NSGCT and that the replacement of cisplatin by carboplatin leads to reduced toxicity.

Steroid treatment of male subfertility caused by antisperm antibodies.

47 subfertile men with significant titres of antisperm antibodies were treated with one of two steroid regimens. The results were assessed by changes in sperm-counts and in serum antibody titres and by subsequent pregnancies. 15 oligozoospermic men were treated with prednisone 5 mg three times a day for 3--12 months. Sperm-counts became normal in 10 men and 4 of their wives became pregnant. 14 men with normal sperm-counts received the same treatment: antibody titres fell slightly and 3 of their wives became pregnant. 18 other men with normal sperm-counts were given one or more courses of methylprednisolone 96 mg/day for 7 days. There was a more pronounced fall in antibody titres in these men, and 7 of their wives became pregnant. Testicular biopsies in 3 men with high titres of antibodies and very low sperm-counts which became normal with prednisone showed adequate spermatogenesis; however, focal round-cell infiltration of seminiferous tubules was observed in 1 case. It is suggested that a steroid-responsive immune orchitis can occur spontaneously in man, and may contribute to the infertility of men with antisperm antibodies.

Combined management of malignant teratoma of the testis.

Intensive chemotherapy with bleomycin and vinblastine was used as initial treatment in patients with advanced testicular teratoma and after relapse following lymph-node irradiation in patients with early-stage disease. Between January, 1976, and March, 1978, 84 patients, 28 with early disease and 56 with advanced disease, were treated. All 28 men with early-stage disease are alive and disease-free. Patients with advanced disease were divided into two groups. Patients with bulky multiple lung metastases and those with liver involvement did poorly, only 4 of 23 (17.4%) being disease-free. Conversely, patients with bulky abdominal nodes and those with limited lung disease did well, 17 of 21 previously untreated patients (80.9%) being alive and disease-free. Within the latter group, 16 patients were managed with chemotherapy and radiotherapy and/or surgery. Of these, 15 (93.4%) are disease-free.

Male infertility due to sulphasalazine.

Four young immigrants whose ulcerative colitis was controlled by sulphasalazine had oligospermia and infertility. No other cause for infertility was found in any of them nor in their wives. Findings on semen analyses rapidly improved in all patients on withdrawal of sulphasalazine, which resulted in four pregnancies in three of the wives. Reintroduction of sulphasalazine was followed by rapid deterioration in the semen of two patients. The frequency and importance of the effect of sulphasalazine on fertility requires further evaluation.

Obstructive nephropathy: successful evaluation with radionuclides.

A non-invasive test of nephron function, the renal parenchymal transit time (P.T.T.) index, is shown to be as accurate as antegrade pressure measurements in diagnosis of renal outflow obstruction. It is more sensitive than conventional methods of demonstrating the associated obstructive nephropathy. P.T.T. is useful in following the effects of surgery, or of temporising, in patients with confirmed or potential outflow tract obstruction. Renal radionuclide P.T.T. analysis gives the functional information essential for the management of patients in whom intravenous urography reveals a dilated renal pelvis.
