Pressure-distention relation in male obstructed urethra.
The pressure-distention relations of the obstructed urethra were estimated from urethral pressure profiles measured with catheters of different diameters. Ten patients with obstruction of proximal and distal urethra were studied. The pressure-distention relations in the corresponding intact parts of the urethra were used as control data. The pressure-distention relation appears to be a good diagnostic indicator of changes in the viscoelastic properties of the urethral tissue at the site of the obstruction.
