[High flow priapism].

Four cases with high flow priapism are described herein. Patient evaluation included intracavernal blood-gasmetry, echo Doppler, selective arteriography of the pudendal artery. Three patients had a previous history of trauma and one patient was on psychotropics. The alpha-agonist drugs and the different shunt techniques did not achieve detumescence. Two embolization procedures of the internal pudendal artery were performed with good long-term results. The other two cases achieved spontaneous detumescence. No complications or secondary erectile dysfunction were observed.

[Renal sarcoma].

Among 322 cases of primary malignant renal tumours reviewed between 1969 and 1991, six were renal sarcoma (1.85%). They all presented earlier symptomatology which was not different from other renal tumours, and nephrectomy was performed in all cases, 5 of which died before 14 months. The histopathological diagnose showed two liposarcoma, two carcinosarcomas, all the others being fibrosarcomas.

[Basis for the study of erectile dysfunction with pudendal evoked potentials].

The evaluation of erectile dysfunction by popliteal and pudendal evoked potentials is not widely utilized in our country, although the foregoing has proved to be a useful technique in the evaluation of a possible neurological etiology. This study describes this simple, fast and low cost method of evaluation and reports the normal ranges. The study comprised 40 subjects; 15 were healthy volunteers and the remaining had consulted for impotence and referred antecedents suggesting a neurological etiology. The results show that a latency of 40.9 +/- 2.1 msec in P1 for the pudendal evoked potentials is normal. Concerning the popliteal evoked potentials, the normal latency for P1 is 38.07 +/- 2.8 msec.

[Value of bone gammagraphy and pain in the follow-up of carcinoma of the prostate].

We reviewed 382 bone scans from 161 patients with prostatic adenocarcinoma submitted to scintigraphic evaluation over the period 1980 to 1988. Each patient had a mean of 2.37 bone scans (1 to 9 scans). Seventy-three patients had positive scans (64 initially and 9 in the course of patient follow-up). Sixty-four presented bone pain (56 initially and 8 in the course of the disease). The remaining 17 patients were asymptomatic throughout follow-up; however, bone metastasis was undemonstrable. In our view, pain is a reliable indicator of the appearance or progression of bone metastasis. Routine follow-up bone scans are unnecessary in patients with positive or negative scintiscans who remain asymptomatic.

[Therapeutic effectiveness and safety of prazosin in the symptomatic treatment of benign prostatic hypertrophy].

74 patients diagnosed as suffering from benign prostatic hypertrophy (BPH) were treated with prazosin for 8 weeks. We look at the evolution of the symptomatology and the urodynamic and morphologic parameters during the treatment and they are compared with the basal ones. The irritative symptoms (nocturia, pollakiuria, imperiosity and dysuria), evaluated by means of a quantitative scale, undergo significant statistical improvement. The same occurred with the obstructive symptoms. Urodynamically, an increase took place in total vesical capacity, maximum, and mean flow, as well as a drop or reduction in non-inhibited contractions. 27 patients suffered adverse effects, which obliged 8 of them to abandon the treatment. Global efficacy was excellent in 20% and good in 52%, whilst it was fair and ineffective in 19 and 9%, respectively.

[Priapism of low flow].

The results obtained after treating 13 patients with low flow priapism diagnosed by cavernous gasometry, penile ecodoppler and cavernosography are explained. Seven cases of priapism (53%) developed following intracavernous injection of vasoactive drugs and had a good response to aspiration lavage and alpha-agonist medication. None of the cases needed shunt technique to achieve detumescence and all showed good evolution with regard to the erectile function. Six cases of priapism (47%) were idiopathic and they all needed some type of venous by-pass. Later, only one had normal erections.

[The phenomenon of obstructive uropathy with minimal or no dilatation].

Obstructive anuria does not necessarily show a marked dilatation of the urinary tract on evaluation with imaging techniques. A case with acute renal failure of this type is presented. We discuss why this condition is caused and how diagnosis can be made quickly. Likewise, we discuss the length of time we can defer renal diversion before rupture of the collecting system supervenes and, consequently, urinary extravasation.
