[Acute renal failure and hypertension].

Ischemic nephropathy could be complicated with hypertension and acute worsening of chronic renal failure secondary to ACE inhibitors or AT receptor antagonist treatments and arterial occlusion. We describe a patient with bilateral renal artery stenosis and hypertension treated with ATI receptor antagonist (valsartan) that developed rapid worsening of renal function that required dialysis. Percutaneous transluminal renal artery angioplasty and stenting, complemented with hydratation and valsartan suppression achieves rapid and sustained recovery of renal function.

Percutaneous embolization for erectile dysfunction due to venous leakage: prognostic factors for a good therapeutic result.

OBJECTIVES: To identify prognostic parameters for patient outcome after embolization for erectile dysfunction (ED) due to venous leakage (VL). METHODS: 23 patients presenting with ED due to pure venous leakage were selected. Intracavernous pharmacological testing, Doppler ultrasound, dynamic cavernosography-cavernosometry and cavernous oxygen tension were done. All patients underwent embolization of the leakage areas visualized. The results were assessed in terms of the response: good, partial or absent. Mean values were calculated for diastolic flow, oxygen tension, maintenance flow and pressure decay, and were compared between the group of patients who responded and the group which did not respond using Student's t test. RESULTS: 26% had a good response, with a mean follow-up of 22 months, if we include partial response and adjuvant therapy this rate rises to 44%. A statistically significant relationship was found between the intracavernous oxygen tension and maintenance flow with a good response to treatment; patients with cavernosography types I and II showed a better response to treatment than those with cavernosography type III. CONCLUSIONS: Maintenance flow, intracavernous oxygen tension, and cavernosography types can be prognostic factors of success in the treatment of ED due to pure VL with embolization.

[Antioxidative state and lipid peroxidation in erectile dysfunction: preliminary study].

OBJECTIVE: The aims of this study were to analyze the cavernosal tissue metabolic status of patients with vascular and psychogenic impotence and attempt to establish metabolic differences between these types of erectile dysfunction. METHODS: 103 patients were classified according to the type of erectile dysfunction into group A (vascular) and group B (psychogenic). Diagnosis was based on clinical history, physical examination, intracavernosal injection test, penile echo-doppler assessment, cavernosography-cavernosometry and nocturnal penile test. Cavernosal and peripheral venous blood samples were obtained from each patient and the lipoperoxide (LPO) levels and total antioxidant status (TAS) were determined. SPSS V9.0 was used for the statistical analysis. RESULTS: The mean age was 62 years (range 32-73). Cavernosal blood lipoperoxide levels were statistically higher (p < 0.05) in patients with vascular impotence (2.45 mumol/L) than in those with psychogenic impotence (1.47 mumol/L). Cavernosal blood total antioxidant status was statistically higher (p < 0.05) in patients with psychogenic (1.40 mmol/L) than those with vascular impotence (1.10 mmol/L). The lipoperoxide levels and total antioxidant status for peripheral blood were 1.68 mumol/L vs 1.60 mumol/L and 1.29 mmol/L vs 1.35 mmol/L, respectively, with no statistically significant differences between both groups. CONCLUSIONS: Cavernosal blood lipoperoxide levels and total antioxidant status can be an indicator of cavernosal tissue metabolic status and function.
