Simultaneous measurement of cystometry and diuresis renography during full and empty bladder in neurogenic bladder patients: a preliminary report.
In 9 patients (4 male and 5 female; mean 24.7 years old) with neurogenic bladder dysfunction, diuresis renography and water filling cystometry were simultaneously monitored with a full and empty bladder, and findings of diuresis renography with a full bladder were compared with those of diuresis renography with an empty bladder. According to O'Reilly's classification, findings of diuresis renography with a full bladder were significantly worse than those of diuresis renography with an empty bladder, regardless of cystometry patterns and bladder compliances. Although every kidney without hydronephrosis on intravenous pyelogram showed normal diuresis renography with an empty bladder, some kidneys with hydronephrosis showed an obstructive pattern even with an empty bladder. These results suggest that in some patients with neurogenic bladder dysfunction, deterioration of the upper urinary tract occurs more easily with a full than with an empty bladder, regardless of bladder pressure and bladder compliance.
