SIMULTANEOUS MEASUREMENT OF CYSTOMETRY AND DIURESIS RENOGRAPHY DURINGFULL AND EMPTY BLADDER IN NEUROGENIC BLADDER PATIENTS - A PRELIMINARY-REPORT

In 9 patients (4 male and 5 female; mean 24.7 years old) with neurogen ic bladder dysfunction, diuresis renography and water filling cystomet ry were simultaneously monitored with a full and empty bladder, and fi ndings of diuresis renography with a full bladder were compared with t hose of diuresis renography with an empty bladder. According to O'Reil ly's classification, findings of diuresis renography with a full bladd er were significantly worse than those of diuresis renography with an empty bladder, regardless of cystometry patterns and bladder complianc es. Although every kidney without hydronephrosis on intravenous pyelog ram showed normal diuresis renography with an empty bladder, some kidn eys with hydronephrosis showed an obstructive pattern even with an emp ty bladder. These results suggest that in some patients with neurogeni c bladder dysfunction, deterioration of the upper urinary tract occurs more easily with a full than with an empty bladder, regardless of bla dder pressure and bladder compliance.
