Abstract:
Objective:To investigate clinical characteristics of urodynamics in elderly male patients with indwelling urinary catheterization.
Methods:Clinical urodynamics of 497 male patients with indwelling urinary catheterization aged 60 years and over from December 2010 to April 2019 in our center were retrospectively analyzed and divided into 3 groups: 60-69-year-old group(n=114), 70-79-year-old group(n=220), and 80-111-year-old group(n=163). According to the catheter indwelling time, the patients were divided into 3 groups: 1-2 weeks group(n=262), 2-4 weeks group(n=47)and over 4 weeks group(n=188). The cause of indwelling urinary catheterization, bladder outlet obstruction, acontractile detrusor and other indicators were observed.
Results:The main cause of indwelling urinary catheterization in elderly men was acute urinary retention(55.1%, 274 cases), in that the most common diagnosis was benign prostatic hyperplasia(90.3%, 449 cases). No statistically significant difference in the different catheter indwelling time-related urodynamics between the different age groups was found(χ2=1.606, 0.199 and 2.477, all P>0.05). There were statistically significant differences both in the incidences of bladder outlet obstruction between the 1-2 weeks vs.2-4 weeks vs.over 4 weeks groups[56.9%(149/262)vs.55.3%(26/47) vs.42.6%(80/188), χ2=9.315, P<0.05)], and in the incidences of acontractile detrusor between the 1-2 weeks vs.2-4 weeks vs.over 4 weeks groups[15.6%(41/262)vs.12.8%(6/47)vs.29.8%(56/188), χ2=15.319, all P<0.05)]. There was no statistically significant difference in catheter indwelling time-related urodynamics between two groups with normal detrusor muscle function and weak detrusor muscle function(P>0.05). Clinical urodynamics had no statistically significant in different age groups(P>0.05).
Conclusions:Bladder outlet obstruction is the main cause of indwelling urinary catheterization in elderly men.Urodynamic examination can be performed 1-2 weeks after indwelling urinary catheterization.Age has no significant effect on the catheter indwelling time-related urodynamics.The duration of indwelling urinary catheterization has little effect on the urodynamic diagnosis in patients with normal or weak detrusor muscle contractile strength.The elderly patients may have acontractile detrusor if the duration of indwelling urinary catheterization is more than 4 weeks.
