Abstract:
Objective:To investigate the urodynamic characteristics in Parkinson's disease(PD)versus multiple system atrophy(MSA)patients with lower urinary tract symptoms(LUTS).Methods:We performed a retrospective study in PD and MSA patients admitted to the First Affiliated Hospital of Zhengzhou University and undergone urodynamic examinations from January 2016 to June 2019.A total of 178 patients, mean age(59.2±9.7)years were enrolled, with 64 PD patients, 74 MSA patients and 40 normal controls.Urodynamic parameters included maximum flow rate(Qmax), post-voided residual urine volume(PVR), bladder compliance(BC), overactive bladder(OAB), maximum cystometric capacity(MCC)and detrusor pressure at maximum flow rate(PdetQmax). Bladder function was assessed.Results:Frequent urination(68.8%)was the most common LUTS in PD patients, as opposed to urinary retention(91.9%)in MSA patients.The Qmax, PdetQmax and incidence of OAB were higher and the PVR were lower in PD patients than in MSA patients [free-flow(FF)-Qmax: (13.5±7.1)ml/s vs.(10.1±5.2)ml/s, U=26.98, P<0.01]; pressure-flow study(PFS)-Qmax: [(13.6±5.7)ml/s vs.(10.5±3.3)ml/s, U=34.90, P<0.01]; PFS-PdetQmax: [(23.9±11.3)cm H 2O vs.(16.3±8.6)cmH 2O, U=35.04, P<0.01]; OAB: (46.9% vs.27.0%, χ2=5.85, P<0.01); FF-PVR: [(30.4±20.0)ml vs.(161.7±79.8)ml, U=-71.81, P<0.01]; PFS-PVR: [(65.9±30.7)ml vs.(212.6±83.0)ml, U=-65.29, P<0.01]. Compared with the control group, the incidences of OAB and PFS-PVR were increased and the MCC and PdetQmax were decreased in the PD group(OAB: 46.9% vs.7.5%, χ2=6.15, P<0.018); PFS-PVR: [(65.9±30.7)ml vs.(22.2±10.4)ml, U=47.25, P<0.01]; MCC: [(305.1±79.7)ml vs.(389.6±65.2)ml, U=-52.13, P<0.01]; PdetQmax: [(23.9±11.3)cmH 2O vs.(37.3±10.3)cmH 2O, U=-49.88, P<0.01]. Compared also with the control group, the MSA group had a lower Qmax, PdetQmax and MCC, FF-Qmax: [(10.1±5.2)ml/s vs.(16.3±4.7)ml/s, U=-50.11, P<0.01]; PFS-Qmax: [(10.5±3.3)ml/s vs.(13.1±5.0)ml/s, U=-27.54, P<0.05]; PdetQmax: [(16.3±8.6)cmH 2O vs.(37.3±10.3)cmH 2O, U=-84.92, P<0.01]; MCC: [(284.3±71.8)ml vs.(389.6±65.2)ml, U=-39.31, P<0.01], a higher PVR, lower bladder compliance(BC)and a higher incidence of OAB(FF-PVR: [(161.7±79.8)ml vs.(22.0±13.0)ml, U=84.82, P<0.01]; PFS-PVR: [(212.6±83.0)ml vs.(22.2±10.4)ml, U=112.54, P<0.01]; BC: (28.4% vs.7.5%, χ2=6.81, P<0.01); OAB: (27.0% vs.7.5%, χ2=17.62, P<0.01). Conclusions:PD and MSA patients with LUTS have bladder dysfunction.MSA patients have more serious bladder dysfunction than PD patients.
