[Temporary urinary derivations: use of the Kehr T tube].

The authors present 10 cases of obstructive uropathy, 8 caused by lithiasis and 2 by retroperitoneal tumours, in which, due to the chronic nature of the processes and to the intense periureteral fibrosclerosis in the place of the stone, temporary derivation of the urine was advisable. After having used several kinds of derivations (nephrostomies, pyelostomies, free ureteral probes), they use Kehr's T tube and comment upon the advantages and benefits obtained with this kind of derivation.

[Crystallography in the analysis of urinary calculi in Spain. Historical review of the Spanish contribution to the subject].

We make a review of the Spanish contribution to the field of crystallography applied to the study of Urinary Lithiasis and assess the current state of the same. We emphasize, by virtue of the number and quality of their works, CIFUENTES, DELATTE and COLLS, SOMACARRERA and ALONSO as pioneers of ultramicroscopic studies. GUILEN CAVERO because of his impressive explanation of Lithogenesis and B. PINTO for his contribution to the generalization of the knowledge of analysed calculation by means of crystallographic methods.

[Ultrastructure of primary or endogenous prostatic calculi. Scanning electron microscopic study].

We make an analysis by means of a Scanning Electromicroscope, of the ultrastructure of 15 Primary Prostate stones. The components identified were: Carboapatite in 14 stones, Hydorxyapatite in 3, Whitlockite in 4 and Wedellite in 2 stones. The ultrastructural findings have enabled us to classify them as follows: 1. Hydroxyapatite stones, which we call "Crystalline", the rarest, due to the predominance of the inorganic component. 2. Carboapatite stones, which possess a great deal of organic material and which we subdivide into "Amylaceous" for those which possess some ovoid formations which appear to us to correspond to amylaceous bodies and "non-amylaceous" for those without them.

[Mixed-nucleus renal calculi].

We made a crystallographic analysis of 87 mixed-nucleus stones and found 4 groups of stones of this kind, which are as follow: urico-oxalic, oxalico-uric, phosphato-oxalic and oxalic-phosphatic. We did not find any mixed-nucleus, urico-phosphatic or phosphatico-uric stones and we explain this fact according to the known lithogenic, metabolic mechanisms, in which urinary pH has an important function.

[Clinical behavior of mixed nucleus reno-ureteral calculi].

We made a statistical study, by means of a computer, of 87 crystallographically-analysed stones, corresponding to 85 patients, assessing different clinical data with the mixed composition of the nucleus of these stones. We deduce that in general, the behaviour of these stones is determined by the interaction of their components, with the main substance predominating. The most significant correlations were obtained when we assessed the sex, age, urinary infection, simple or coralliform morphology of the stone, the number of stones formed, permanent, homolateral, kidney damage, overall kidney failure and procedure for removing the stone. We did not find any valid links when we compared the family record of lithiasis, affectation of the counterlateral kidney and the fact whether the stone was from the right or the left.
