[Is there any obstruction other than prostatic obstruction in Idiopathic Parkinson's Disease?]

OBJECTIVE:To highlight the existence of pseudo-dyssynergia in Idiopathic Parkinson's Disease (IPD) constituting a functional bladder outlet obstruction. MATERIALS AND METHODS:A retrospective study was conducted by including men with a confirmed diagnose of IPD who participated in the SIROCCO rehabilitation program. Patients included clinically exhibited overactive bladder and voiding dysfunction without prostatic hypertrophy ultrasounded. They have been clinically assessed by the Urinary Symptoms Profile (USP) urinary symptom score. Bladder outlet obstruction was assessed by the pressure-flow study. Urodynamic obstruction has been quantified by the bladder obstruction index which depends on detrusor pressure at maximum flow rate and maximum flow rate. It has been defined by a BOOI>40. RESULTS:The pressure-flow profile was analyzed in 5 patients who met the inclusion criteria. In this group of 5 patients with IPD, the diagnosis was made on average 10.6 years (7-14) before the pressure-flow studies were performed. Our results objectified 4 patients obstructive among 5 and one equivocal patient. A striated pseudo-dyssynergia was found in the 3 obstructive patients and associated with a smooth pseudodyssynergia in one patient. CONCLUSION:We have observed, in this short series, a pseudo-dyssynergia by subjects suffering from IPD. LEVEL OF EVIDENCE:3.
