EVALUATION OF UPPER URINARY-TRACT DYNAMICS BY DIURESIS RENOGRAPHY IN PATIENTS RECEIVING URINARY RESERVOIR OPERATION - COMPARISON OF FULL AND EMPTY RESERVOIR

Upper urinary tract dynamics was evaluated using diuresis renography d uring full and empty reservoir in 14 patients (11 men, 3 women, 13-70 years old) with intestinal urinary reservoir or intestinal bladder aug umentation. Types of operation were Mainz pouch urinary diversion 5, M ainz neobladder to urethra 5, Kock pouch urinary diversion 2, and Main z bladder augumentation 2. Diuresis renography was performed using Tc- 99m-DTPA and furosemide during full and empty reservoir, and several p arameters (T(max), T75, T50, GFR) in addition to the patterns of renog ram were evaluated. In the normal control, none of the parameters of t he diuresis renogram with full bladder differed from those with empty bladder. In 5 of 14 patients, abnormal waves on cystometry (CMG) were found, and in 4 of these 5 patients, the patterns of diuresis renogram of full reservoir were worse than those of empty reservoir. However, the patterns of diuresis renogram of full reservoir were not different from those of empty reservoir in 9 patients without abnormal waves on CMG. In conclusion, renal injury may easily occur in patients with in testinal reservoir and abnormal waves on CMG.
