[Fibroepithelial polyp of the urethra in an adult].

We present the case of a fibroepithelial polyp of the prostatic urethra in a forty-five year old patient. This type of polyp is rare in the adult. The principal symptoms which the patient presented were haematuria and an intermittent reduction in micturitional flow. Endoscopic images of the tumour are shown and certain details of its histology; this is a polypoid lesion of loose connective tissue covered by typical urothelium, with occasional fascicles of smooth muscle, no prostatic-type glandular structures and no appreciable inflammatory component.

[Adrenal ectopy in epididymis].

OBJECTIVE: To report a case of ectopic adrenal in the epididymis. METHODS: A 17-year-old male consulted for a left varicocele and complaints referred to the right epididymis a year and a half after an episode of acute epididymitis. A nodule was excised from the epididymis. RESULTS: The pathological analysis showed an 0.4 cm nodule comprised of adrenocortical tissue. CONCLUSIONS: Ectopic adrenal cortical tissue is a benign lesion. Although routine search for this lesion is not indicated, it should be resected for histological analysis and differential diagnosis when it is found during a surgical procedure in this area.

[Non-functional renal paraganglioma associated with carotid paraganglioma and appendicular mucocele].

OBJECTIVE: A case of nonfunctional renal paraganglioma associated with appendicular mucocele and metachronic carotid paraganglioma is presented. METHODS/RESULTS: A 68-year-old patient consulted for abdominal pain. Patient evaluation with US, CT and opague enema showed an elongated mass that compromised the cecum and a solid mass in the right kidney. The patient underwent appendectomy and radical right nephrectomy. The anatomopathological findings showed an appendicular mucocele and renal paraganglioma. The postoperative hormone analyses were normal. A carotid paraganglioma was removed 8 months later. CONCLUSIONS: Renal tumors arising from neural crest cells are uncommon. To our knowledge, this is the third case of nonfunctional renal paraganglioma reported in the literature. The associated appendicular mucocele was an incidental finding.

[Perioperative transfusion in prostatic surgery].

OBJECTIVE: To analyze the likelihood of perioperative transfusion in prostate surgery. METHODS: The records of patients who underwent prostate surgery at the Hospital Central de Asturias en 1996 were reviewed. The abstracted patient discharge records, encoded according to the ICD-9-CM, were analyzed for gender, age, diagnosis, surgical and non-surgical procedures, including transfusions of blood products. RESULTS: 29 (14.2%) of 204 operated patients required transfusion. By univariate analysis, the likelihood of requiring transfusion was significantly higher in patients with cancer (28.8%), patients undergoing radical prostatectomy (40%), and those undergoing more than one surgical procedure (21.2%). By multivariate logistic regression analysis, the surgical procedure, age and simultaneous urinary bladder surgery were related with the likelihood of requiring transfusion. The adjusted odds ratio for perioperative transfusion was 10.14 times in radical prostatectomy than in transurethral prostatectomy, 2.67 times for patients more than 75 years than in those aged less, and 2.85 times in patients undergoing simultaneous urinary bladder surgery than those who do not. CONCLUSIONS: Due to the wide range of variability of the adjusted likelihood for transfusion in prostate surgery (3.5% to 83.4%), estimation of the individual likelihood for transfusion could be useful for planning surgical transfusions, pretransfusion tests and autologous transfusion in these patients.

[Adrenal tuberculosis. Diagnosis using polymerase chain reaction].

OBJECTIVE: To present a case of a patient suffering from adrenocortical insufficiency (Addison's disease) and to demonstrate the utility of the polymerase chain reaction (PCR) in the diagnosis of adrenal cortex tuberculosis. METHODS/RESULTS: Herein we describe a patient with Addison's disease who had developed pulmonary tuberculosis a few years earlier. CT and PCR test were utilized in making the diagnosis. CONCLUSION: Although adrenocortical tuberculosis is uncommon today, it must be considered when evaluating adrenocortical insufficiency, especially if the patient has or has had tuberculosis. Although Mycobacterium tuberculosis might not be demonstrated by bacteriologic techniques, PCR can be useful in making the etiological diagnosis.

[Pure prostatic leiomyoma].

We report a case of pure leiomyoma of the prostate, an uncommon benign tumor with a leiomyomatous component distinct from benign prostatic hyperplasia. The literature is reviewed and several considerations are put forward relative to the etiopathogenesis, clinical and anatomopathological features, differential diagnosis and prognosis of this tumor.

[Villous polyp of the urethra].

Villous polyps of the urethra are rare. This condition can be seen more frequently in patients aged 30-40 years. Hematuria is usually the major symptom. Generally, the polyps are localized in or around the verumontanum and do not recur after TUR or electrocoagulation. A case of villous polyp of the verumontanum is described in a patient who presented with symptoms and signs of obstructive micturition. The patient continues to be asymptomatic 6 months following treatment by electrocoagulation.

[Mucinous adenocarcinoma of the urachus].

Malignant tumours of the urachus are very rare and they give certain difficulty in their differential diagnosis with vesical cupula adenocarcinoma. We present a case of mucinous adenocarcinoma of the urachus in a 75-year-old patient and we analyse the behaviour, clinical background, diagnosis and treatment of these tumours.

[Activity of total cholesterol and its HDL fraction in vasectomized patients. A 3-month follow-up].

Vasectomy is an ever-increasingly used contraceptive method owing to its effectiveness and easy execution, although various studies have questioned its innocuousness. We have studied various parameters in 70 patients three months before and after the vasectomy was performed. The analytical factors controlled were as follows: glycemia, triglycerides, total cholesterol, HDL-cholesterol, LDL cholesterol, FSH, LH, testosterone and estradiol. Other data handled were arterial tension and body weight index. We questioned them about physical activity, distributing them into three groups, and about family history of arteriosclerosis, distributing them into two groups. Three months after the operation we found an increase in body weight index of 24.11 +/- 2.49 to 24.77 +/- 2.51, with a p less than 0.01. Total cholesterol also rose from 201 Cae 39 mgr% to 208 +/- 38 mgr% with a p less than 0.05. We also observed a drop in arterial tension. Patients with no family history of arteriosclerosis had an increase of total cholesterol of 199 +/- 39 mgr% to 210 +/- 35 mgr% with a p less than 0.001. In the heavy smoker group, total cholesterol also rose from 203 %/- 48 mgr% to 214 +/- 40 mgr% with a p less than 0.05. We discuss our results and our surgical complications and our conclusion in that, based on our study, we cannot assert the vasectomy plays a role as a risk factor of arteriosclerosis.
