CORRELATION OF UPPER AND LOWER URINARY-TRACT FUNCTION IN PATIENTS WITH NEUROGENIC BLADDER - EVALUATION USING SIMULTANEOUS MEASUREMENT OF CYSTOMETRY AND DIURESIS RENOGRAPHY WITH FULL AND EMPTY BLADDER

Diuresis renography and water filling cystometry were simultaneously p erformed with the bladder full and with the bladder empty. The finding s of diuresis renography with a full bladder were compared with those of diuresis renography with an empty bladder, in 9 patients (4 male an d 5 female. mean 24.4 years old) with neurogenic bladder dysfunction. According to O'Reilly's classification, the findings of diuresis renog raphy with a full bladder were significantly worse than those of diure sis renography with an empty bladder, regardless of cystometry pattern s and bladder compliance. These results suggest that in patients with neurogenic bladder dysfunction, a full bladder in itself can cause det erioration of the upper urinary tracts, regardless of bladder pressure and bladder compliance.
