[BCG in superficial carcinoma of the bladder. Authors' experience].

Contribution of 95 patients with surface vesical tumour managed with UTR and endovesical BCG. The response was absence of recurrence in 68.4% cases in Ta stage, 63% in T1 and 66.7% in 'in situ' carcinoma. Therapy tolerability was good, with few side-effects. We conclude that BCG endovesical instillation as co-adjunctive therapy to UTR in surface vesical tumours has been shown to be effective for the period under study.

[Leukoplakia of the upper urinary tract].

Leukoplakia is a morphological term that attempts to define keratinizing desquamative squamous metaplasia of the transitional epithelium. It is uncommon in the upper urinary tract (less than 100 cases have been reported) and has been attributed to infection or mechanical injury to the epithelium and/or genetic factors. We present a case of leukoplakia in a male patient with renal tuberculosis that had been in remission for the past 15 years. Eight years earlier he had intermittently passed keratin laminas (pathognomonic of leukoplakia) during the course of various episodes of nephritic colic. After discarding a reactivation of tuberculosis and malignancy of the metaplastic lesion, we continued conservative treatment with radiologic and cytologic control evaluations.

[Urinary diversions: our experience and selection approach].

Retrospective review of 126 urinary by-passes performed in our service over the last 15 years where efficacy and complications arisen from the ureteroileal by-passes, ureterosigmoidostomy and skin ureterostomy are analyzed. Patients were found to be pre-operatively homogeneous with no statistically significant differences with regard to age, renal function or previous radiotherapy, except in the case of ureterostomies which are always initiated from a poorer renal function and general condition. It was concluded that there was no difference between the various Bricker types according to the anastomosis, which allows joint a comparison with other groups. After three months, Bricker's showed better radiologic evolution than Goodwin's (p less than 0.08) and a statistically lower number of complication (p less than 0.05) therefore establishing they should be the choice procedure versus any other type of by-pass. Literature review with regard to results and conditions of container reservoirs and vesical substitutions, evaluating their contraindications within the neoplastic scope and/or psychosocial range, as well as comparing the reflux, stenosis and infection rates with our series, make the ureteroileal by-pass a technique entirely legitimate at present.

[Adrenal masses discovered incidentally].

The introduction of new diagnosis techniques has made the study of the suprarenal gland much more accessible. In particular, ultrasonography, CAT and MRI have contributed to the increased detection of suprarenal masses by chance, and this raises problems when it comes to deciding the attitude to take to the diagnosis of these masses. We present nine suprarenal tumours, most of which appeared in the course of follow-up of patients suffering from carcinoma of the bladder. On detecting a suprarenal mass, we carry out a morphological study with CAT as well as determination of hormonal activity and puncture with cytology of the mass, according to the schema proposed by Copeland. We comment on the most significant clinical aspects and on the criteria of action proposed by various authors.
