DRUC(Double Contrast Retrograde Urethrocystography), which was a combination of air cystography and retrograde urethrography with the patient in an exaggerated Trendelenburg's position allowing the contrast medium injected into bladder to be accumulated at the bladder base and dome far from trigone, showed good visualization of the prostatic urethra, bladder neck, bladder base and wall in contrast to the conventional, retrograde urethrography. The authors analyzed DRUC findings of 32 cases of benign prostatic hypertrophy, 3 case of prostatic cancer and 50 cases of normal healthy men performed at Pusan National University Hospital for 9 months from January 1984 to September 1984. The results obtained were as follows: 1. DRUC findings of normal control group were normal pattern of prostatic urethra, semioval shaped bladder neck, single narrow tubular intravesical stream, no elevation of bladder base and no trabeculation of bladder wall. 2. DRUC findings of B.P.H. were spreading f prostatic urethra, spreading, displacement, smooth multidirectional compression of bladder neck, widening of inner orifice of bladder neck, smooth elevation of bladder base, trabeculation of bladder wall and variable types of intravesical stream such as normal, broad, double central stream, associated peripheral umbrella stream and no intravesical stream. 3. DRUC findings of prostatic cancer were rigidity of prostatic urethra, nodular multidirectional compression of bladder neck, multiseptation of peripheral intravesical stream, nodularity of bladder base and trabeculation of bladder wall. 4. DRUC, which added to double contrast method and position change of patient, showed more delicate changes of bladder neck, base and wall as well as prostatic urethra in contrast to simple RUG. We observed that changes of bladder neck and intravesical stream were singificant in analyzing abnormal enlarged prostate, and could differentiate B.P.H. from prostatic cancer simply by noting sharphy dem rcated bladder base.
