Abstract:
Objective:To examine differences in urodynamic changes between central neurogenic bladder(CNB)and peripheral neurogenic bladder(PNB)in elderly patients.Methods:A total of 57 elderly patients over 60 years old with neurogenic bladder(NB)were divided into a CNB group and a PNB group based on the types of nerve injuries.Data on urodynamic parameters recorded for the two groups were compared and analyzed.Results:The rate of detrusor overactivity(DO)in the CNB group was significantly higher than that in the PNB group [66.7%(16/24)vs.36.4%(12/33), χ2=5.105, P=0.024]. There were significant differences between the two groups in maximum bladder capacity(MCC)[(277.8±101.1)in the CNB group vs.(481.4±110.2)ml in the PNB group, t=-7.149, P=0.001]and in safe bladder capacity(SBC)[(283.2±28.8)ml in the CNB group vs.(348.6±33.9)ml in the PNB group, t=-7.636, P=0.000]. There was no significant difference between the two groups in the maximum urine flow rate, residual urine volume, urination volume, leak point pressure, or detrusor pressure at the maximum urine flow rate(all P>0.05). In the CNB group, 8 patients had normal bladder sensation, 4 had disappeared bladder sensation, 10 had decreased sensation, and 2 had increased sensation.In the PNB group, 9 patients had normal bladder sensation, 4 had disappeared bladder sensation, 14 had decreased sensation, and 2 had increased sensation.There was no statistical significance in SBC between different sensation levels within each group( P>0.05). Conclusions:There are differences in urodynamic characteristics between the elderly patients with CNB and those with PNB.Decreases in MCC, SBC and DO are more likely to occur in CNB.
