[Vesicourethral dysfunction in the acquired immunodeficiency syndrome (AIDS)]. / Disfunción vesicouretral en el síndrome de inmunodeficiencia adquirida (SIDA).

OBJECTIVES: Ten patients with AIDS and voiding disorders were assessed to determine the most common type of lower urinary tract dysfunction and its possible usefulness in detecting neurological disease. METHODS: A complete urodynamic evaluation was performed. RESULTS: The most common symptom was urge incontinence and the most common urodynamic finding was detrusor-external sphincter dyssynergia. Of the 5 patients found to have a neurological disorder, only 3 had demonstrable functional disorder of the lower urinary tract (2 patients had detrusor hyperreflexia: one of them had a history of encephalopathy from HIV and the other patient had polyneuritis; the third patient had myelitis and a urodynamically diagnosed sympathetic decentration. CONCLUSIONS: Knowing the functional disorders of patients with AIDS can avoid complications and improve patient quality of life. Furthermore, it can be useful in detecting an existing neurological lesion or one that may develop in the future.

[Obstructive uropathy as a complication of aortic disease and reconstructive peripheral vascular surgery: report of 4 cases and review of the literature]. / Uropatía obstructiva como complicación de la patología aórtica y de la cirugía reconstructiva vascular periférica: presentación de 4 casos y revisión de la literatura.

OBJECTIVES: Ureteral injury can be a complication of peripheral vascular reconstructive surgery or aneurysm of the abdominal aorta. The present study analyses 4 cases of obstructive uropathy; 3 following peripheral vascular reconstructive surgery and 1 from aneurysm of the abdominal aorta. METHODS: All 4 patients were prospectively evaluated. RESULTS: Both renal units were compromised in all 4 cases. The initial management consisted of internal urinary diversion with a double J catheter. Ureterolysis was performed in one case of unresolved uropathy secondary to prior bypass surgery. One case with uropathy due to infection of the vascular prosthetic graft required graft replacement. CONCLUSIONS: The risk of ureteral injury is likely to be seen more often due to the increasing number of operations on the vascular tree and enhanced survival of patients with aortic aneurysm. Prevention of the foregoing complication includes doing US and/or IVP early postoperatively and in the first 4 months following surgery. Patient management is initially conservative.

[Renal carcinoma with tumor embolism of the supradiaphragmatic inferior vena cava: therapeutic alternatives and review of the literature]. / Carcinoma renal con trombo tumoral en vena cava inferior supradiafragmática: opciones terapéuticas y revisión de la literatura.

We report a case of a man with a left renal cancer and vena caval thrombus extending to the right atrium, that was not possible to remove because infiltration of the posterior plane was detected intraoperatively. The patient was rehospitalized for intractable haematuria. He underwent selective embolization of the left renal artery with ethanol and coil. There were no complications and the patient is well seven months after the procedure. We review the literature on the diagnostic and therapeutic options in such cases. We can conclude that it is necessary to know the exact stage of the primary cancer in order to choose the best treatment. MRI or dynamic CT should be utilized to determine the presence of infiltration of adjacent structures or distant metastasis. Radical nephrectomy and the removal of the caval thrombus afford the only possibility of survival in these patients.
