The Prevalence of Detrusor Underactivity and its Symptoms Co-relation with Urodynamic Study Findings in Patients with Lower Urinary Tract Symptoms

PURPOSE: This study determines the prevalence and clinical presentation of detrusor underactivity (DU) and its urodynamic characteristics in adult patients with lower urinary tract symptoms (LUTS). PATIENTS AND METHODS: This retrospective study has reviewed the symptoms and urodynamic study (UDS) findings of 283 patients with LUTS. Chi-square analysis was used to present the prevalence of UDS characteristics in both sexes. RESULTS: Out of records of 206 patients included in this study, fifty-one (24.76%) patients were diagnosed with DU based on bladder contractility index. Storage lower urinary tract symptoms were the most prevalent characteristic presentation in both sexes as compared to the difficulty in voiding, recurrent urine retention, and urinary incontinence. Bladder outlet, sphincter EMG findings, and degree of DU were significantly correlated with gender. CONCLUSION: DU is a prevalent and sophisticated bladder pathology rather than a simple one. It requires more attention from the urologists, and evaluations, including UDS, to differentiate it from other pathologies.
