[Vesicovaginal fistulae: review of our caseload]. / Fístulas vésico-vaginales: revisión de nuestra casuística.

Presentation of a review of vesico-vaginal fistulae diagnosed and treated in our Hospital between 1978-1992. There has been 20 cases. Etiology is varied, with predominance of cases due to gynaecological surgery. Considerations on diagnostic tests used in each case and the various therapeutical approaches applied, as well as on the results obtained. A revision is made of literature available on this condition.

[Early biochemical indicators of renal damage in arterial hypertension]. / Indicadores bioquímicos precoces de daño renal en la hipertensión arterial.

Hypertensive nephropathy is an important complication of arterial hypertension, being a cause of chronic renal insufficiency in a considerable number of patients. For years it has been attempted to find an useful marker of nephropathy in the incipient phases of the disease. We revised the main biochemical indicators of renal damage, paying special attention to hyperuricemia, microalbuminuria, and urinary excretion of beta-2-microglobulin and N-acetyl-beta-glucosaminidase. Each one of them expresses alterations in the glomerular filtrate, lesion of capillary endothelium or anomalies of the tubular function. None of them demonstrated to be specific to nephroangiosclerosis, but they guide us on the structural and functional alterations occurring in the first stages of hypertensive nephropathy.
