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 during full and empty reservoir in 14 patients (11 men, 3 women, 13-70 years old) with intestinal urinary reservoir or intestinal bladder augmentation. Types of operation were Mainz pouch urinary diversion 5, Mainz neobladder to urethra, 5, Kock pouch urinary diversion 2, and Mainz bladder augmentation 2. Diuresis renography was performed using 99mTc-DTPA and furosemide during full and empty reservoir, and several parameters (Tmax, T75, T50, GFR) in addition to the patterns of renogram were evaluated. In the normal control, none of the parameters of the 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 intestinal reservoir and abnormal waves on CMG.
