[Ultrasonographic (intra- and extraluminal) pattern of cervico-urethral anastomosis after radical prostatectomy].

Thirteen patients, mean age 61 years (range 54 to 71), diagnosed with prostate adenocarcinoma underwent radical prostatectomy. To achieve a diagnosis they were all performed blood PSA determination, digital rectal examination, transrectal ultrasound and a prostate ultrasound-guided biopsy by automatic gun puncture. Serum PSA quantification, digital rectal examination and transrectal ultrasound were repeated in the immediate post-operative, and three and six months after surgery. Through the information obtained with endocavitary ultrasound, the lumen of the cervicourethral anastomosis and the perianastomotic tissue was assessed. Transrectal ultrasound plays a relevant role in the follow-up of patients undergoing radical prostatectomy. When a patient with prostate radical surgery shows an elevation of serum PSA and/or abnormal digital rectal examination, an ultrasound-guided biopsy (at the node or perianastomotic area) is indicated.

[Paratesticular neoplasms of mesenchymatous origin. Clinico-pathologic study].

There is a group of malignant intrascrotal tumours which represent a very small number when compared to testicular neoplasias and which are known as paratesticular neoplasias. More than 90% belong to the sarcomatous species. From a clinical point of view and based on the patient's age, two groups can be distinguished: sarcomas affecting children and adolescents (primarily rabdomiosarcomas) and those occurring in adulthood, the more frequent histopathological variants being fibrosarcoma, leiomiosarcoma and liposarcoma. This work contributes five paratesticular sarcomas (two rabdomiosarcomas, one liposarcoma, one leiomiosarcoma and one fibrosarcoma). The features related to histogenesis, diagnosis (revealing signs and clinical examination), natural history (dissemination routes based on histopathology) and treatment are reported. With regard to treatment, both the local surgery (total orchiectomy by inguinoscrotal approach with or without hemiscrotectomy), and indications for lymphadenectomy and radiotherapy in relation to staging are discussed though insisting on the chemotherapy approach.

[Clinical features, diagnosis, and treatment of tumor lesions arising in the adrenal gland].

Between 1981 and 1993, 14 patients with tumoral adrenal disease were diagnosed and treated in the Urology Services of both Hospitals. Nature of the adrenal disease was functional in 8 patients (two carcinomas and six pheochromocytomas) and non-functional in the rest (three carcinomas, two adenomas and one myelolipoma). Reference is made to the clinical manifestations and laboratory tests related to hormonal activity, depending on whether the tumour is functional or non-functional, chromaffin or non-chromaffin. Patients with functional carcinomas had Cushing's syndrome, with very clear virtilization signs. Urine 17-hydroxycorticosteroid, 17-cetosteroides and cortisol were all increased, same as plasma cortisol. Patients with pheochromocytomas had hypertension and headaches (six patients), sweating (five patients), anxiety (four patients) and loss of weight (two patients). All of them had increased urine vainillylmandelic acid and catecholamines. Clinical signs and symptoms of non-functional tumours were related to bulk growth and size (in the three carcinomas), and sometimes was highly anodyne, or even absent (in the two adenomas and the myelolipoma), the cause of discovery being accidental during an ultrasound examination. An analysis is made of the different imaging diagnostic procedures performed, such as IVU (performed in 13 patients) with a 38.4% resolutory power; ultrasound (performed in 11 patients) with an 81.8% resolution; CAT (performed in 6 patients) with a 100% resolution capacity and arteriography (performed in 3 patients) with a 100% resolution power, although patients had previously undergone ultrasound and CAT.(ABSTRACT TRUNCATED AT 250 WORDS)

[Urethral duplication: report of 2 clinical variants].

The present paper is a contribution of two cases of urethral duplication. The first one developed in a paediatric patient and corresponded to a bifid urethra with a pre-anal branch. Diagnosis was based on the patient's signs and symptoms (perianal dripping during miction) and both retrograde and mictional urethrocystography. The therapeutical approach consisted in complete removal of the accessory or supernumerary urethra. The second case developed in an adult patient and the duplication corresponded to a "rifle" urethra. The patient's clinical picture (urinary retention) justified a radiological study of the urethra leading to diagnosis. The therapeutical approach followed was endoscopic resection of both ducts and the surrounding prostatic tissue. Features related to the embryology, signs and symptoms, and therapeutic approach of these malformations are referred.

[Retropubic radical prostatectomy. II. Neuroanatomy of the pelvic plexus, impotence and urinary incontinence].

The present paper reviews the course of the nerves that comprise the pelvic plexus and intervene in the mechanisms of sexual strength and urinary continence. By means of cross-sectional and sagittal incisions in prostates obtained through necropsies the neurovascular bundle, intimately related to the prostatic gland, is studied. Based on the information obtained in the study we raise a series of suggestions all related with the surgical technique of radical retropubic prostatectomy.

[Wallstent prosthesis, urethral stenosis, and prostatic nodular hyperplasia. Presentation of our experience].

The present paper reviews our experience in the use of Wallstent prosthesis. We contribute a total of seven patients which presented with bulbar urethra stenosis (five cases) and benign prostate hyperplasia (two cases), all of which had undergone periodical dilation prior to the prosthesis implant as well as various endoscopic urethrotomies. Here, we report the indications, exclusion criteria, criteria for evaluation of results, and brief description of the technique or method used for the prosthesis implant. Finally, we report on the procedure's advantages and the need to conduct extensive studies (prospective and randomized) in order to clarify the place such prosthesis may take within the therapeutic field of stenosis of the urethra, and in benign prostate hyperplasia.

[Transcervical resection (TCR) in uterine pathology].

Review of our experience in transcervical resection. We contribute a total of 25 patients aged between 53 and 82 (mean age, 69 years), which presented with repeat metrorrhagia. The metrorrhagias were related to perimenopausal hormonal disorders (14 cases), submucosal uterine myoma (6 cases) and diffuse leiomyosarcoma (5 cases).

[Transurethral echography in the staging of bladder neoplasms].

Forty vesical neoplasias in various stages and which were treated through transurethral resection followed by chemotherapy, in accordance to the currently accepted approach, were studied using transurethral ultrasound techniques. A histochemical correlation is established based on the proposed U.I.C.C. grading (T.N.M.). Such correlation coincides in 88.2% of cases for the "unified" Ta-T1 stage; 70% for T2; 88.8% for T3; and 100% for T4.

[Vesiculography with echo-guided transperineal puncture: a complement to intracavitary transrectal echography].

The present paper is a presentation of our experience in the study of seminal vesicles through transperineal ultrasound-guided puncture vesiculography (T.U.P.V.). Explanation of the technical procedure, performance of an analysis of indications and evaluation of its advantages and disadvantages. We consider that T.U.P.V. is another technique to further study the processes affecting the seminal vesicles.

[Treatment of obstructive processes of prostatic origin with the Fabian prosthesis].

The present report is a contribution of our experience on the use of Fabian's prothesis. All patients had a urethral obstructive process which resulted from a hyperplastic or carcinomatous prostatic disease for which open- or endoscopic-surgery was totally contraindicated due to the patients' general status as a result of major cardiorespiratory disorders. A literature review and an evaluation of both indications and contraindications for using such prothesis was made.
