[Wünderlich syndrome caused by metastatic gastric sarcoma in the kidney. Report of a case].

Contribution of one case of Wünderlich Syndrome secondary to a simple metastasis to the right kidney from a gastric sarcoma operated three years earlier. Pain, palpable mass on the side and decreased haematocrit were the primary symptoms. Diagnosis was confirmed by Computerized Axial Tomography. The therapeutical approach was radical nephrectomy. At 5 years, this female patient remains alive showing no evidence of tumoral disease in the follow-up controls performed.

[Controversies and progress in the diagnosis and treatment of benign prostatic hypertrophy. Personal experience].

Historically, non surgical procedures awakened little interest among urologists because surgery represented a definite solution with acceptable morbidity and mortality rates. Currently, the diagnosis and management of BPH is pointed towards a greater understanding of those prostate conditions with a trend to obstruction, using more refined methods to assess the severity of the obstruction, identification of predictive parameters of the therapeutical response, and evaluation of the various treatment alternatives based on safety and cost-efficiency parameters.

Evaluation of the efficacy of oral methotrexate in the prevention of recurrence of superficial bladder tumours.

Twenty-four patients with previously untreated T1 transitional cell carcinoma of the bladder were treated with oral methotrexate 50 mg weekly for 18 months. Thirteen developed tumour recurrences (recurrence index 11 per 100 patient months at risk) and in one-third of the patients treatment was stopped because of unwanted side effects. These results are no better than our previous experience with intravesical Adriamycin, thiotepa or cisplatin.

[Carcinosarcoma and papillary transitional cell carcinoma coexisting in the same bladder].

A case of synchronically coexistent carcinosarcoma and transitional cell carcinoma, with separate neoplastic processes in the same urinary bladder is presented. This tumour association is as far as we know, the second case reported in the literature. Carcinosarcoma was formed by an epithelial component represented by a high level transitional cell carcinoma and a mesenchymal component characterized by an unspecific fusocellular sarcoma with chondrosarcomatous differentiation. An immunohistochemical analysis was performed, confirming the dual nature of the carcinosarcoma.

[Conservative treatment with transurethral resection of stage T2 cancer of the bladder: retrospective study].

We carry out a review of all the primary bladder T2 tumours in the service in order to evaluate the possibilities of conservative treatment in this category of tumour. Despite being tumours that infiltrated the muscularis, there were all treated initially by transurethral resection. Minimum criteria for classification were the case history, urographies, bimanual touch under anaesthetic and transurethral resection of all tumoural formations, including the whole bladder wall and pericystium. It is a group of 73 patients, 66 males and 7 females, having an average age of 65.6 (range 51-58 years old), with primary transitional bladder tumour, who were followed up over a period ranging from 3 months to 10 years, three years on average. 55 (75.3%) are single tumours and 18 (24.6%) multiple tumours. The degree of anaplasia is G2 in 23 (31.5%) and G3 in 50 (68.5%). Of the 73 patients, 43 (58.9%) 43 (58.9%) are free of disease, 33 (45.2%) of them after a single transurethral resection and 10 who required various transurethral resections due to fresh occurrences of lesser degree and stage. The probability of survival of T2 tumours at 5 years is 72% with a margin of reliability of 11% (p less than 0.05).

[Prospective study for the evaluation and prophylaxis of urinary tract infections, secondary to the intravesicular instillation of cytostatics].

The aim of this study is to ascertain the number of urinary infections that occur after every catheterization for the instillation of an endovesical cytostatic and to attempt to reduce the percentage of infections by means of specific plans and methods. The study was carried out during the months of April, May, June, July, September, October and November 1988 and the collection of urine for culture was laid down as standard practice in all patients before instillation. In the same way, a urine sample was studied if the patient displayed symptomatology after instillation. 474 instillations were carried out on 77 patients during the above-mentioned period of time. The number of urine samples collected with significant bacteriuria was 18, which represents 3.8% (reliability margin 2.2%-6%, p less than 0.05).
