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