[Pyelomanometry in obstructions of the upper urinary tract. Apropos of 26 cases]

Pyelomanometry can be used in cases of ambiguous dilatation, to measure the pressure in the upper urinary tract during constant-flow perfusion through a percutaneous catheter (Whitaker's test). After recalling the principles of this method, and the technical procedure, the authors go on to discuss twenty six cases, analyzing the results, and comparing the advantages of this procedure with other methods of exploration.
