Bladder function in healthy elderly males.

Bladder function was studied in 20 healthy elderly male volunteers using cystometry, uroflowmetry and voiding cystourethrography. Two persons were excluded from the study as neurological examination had shown evidence of organic neurological disease, and one person did not complete the study. 53% of the remaining 17 persons had detrusor hyperreflexia. Urinary flow rates were reduced and maximal intravesical pressures elevated in the persons studied, although they claimed to have a normal voiding pattern. No correlation was found between the reduction of urinary flow rate respectively increase in maximal intravesical pressure and the presence of detrusor hyperreflexia. The high incidence of detrusor reflex disturbances thus suggests that incipient infravesical obstruction in old age and possible subclinical impairment of the central nervous control of the micturition reflex are major etiological factors in detrusor hyperreflexia.

Disturbances of micturition in Parkinson's disease.

During the years 1970-1974, a total of 44 patients referred by neurologists to the Urological Laboratory were classified in the following groups: paralysis agitans (27), postencephalitic parkinsonism (5), cerebral arteriosclerosis and parkinsonism (7) and cerebral arteriosclerosis and parkinsonism, suspected (5). Bladder function was assessed on the basis of cystometry and urodynamic investigation. A high frequency of supranuclear bladder paresis (SNP) was found, although unequally distributed in the different diagnostic groups. Stereotactic operations on the thalamic nuclei seemed to be correlated with SNP. The question was raised whether SNP was part of the parkinsonian syndrome or merely signs and symptoms related to ageing.
