AbstractObjective: The aim of this study is to establish the importance of urodynamic investigations in women diagnosed with stress urinary incontinence (SUI) who have indication of surgical treatment.Methods: We performed a retrospective study over a period of 3 years (January 2012-December 2014) in Clinic of Urology from Tirgu Mures. The inclusion criteria were: female patients diagnosed with SUI having indication of surgical treatment and the existence of urodynamic investigations (uroflowmetry and pressure-flow study). We evaluated 118 patients with SUI. From this patients, 24 cases (20.3%) accomplished the criteria from above.Results: We included in this study 24 patients aged 64.25+/−8.25 (standard deviation). Pressure-flow study revealed an impaired detrusor contraction in 13 cases. Statistical anaysis pouved a relation between existence of post void residual urine (PVR) and underactive detrusor (UD) (p=0.01). There is no correlation between maximum flow rate (Qmax) and UD, r=0.18 (CI= −0.2-0.5), p=0.3 and between normal value of Qmax and normal detrusor pressure (Pdet), r= 0,28(CI=−0.6-0.8), p=0.58. Also there is no relation between a low Qmax and UD, p=0,5. There is a statistical relation between increased abdominal pressure (Pabd) and UD, p=0.02.Conclusions: Uroflowmetry has the role to guide us concerning the micturition process Pressure-flow study is indicated in management of SUI, in selected cases, in patients with voiding symptomatology, the suspicion of a detrusor contractility dysfunction, abnormal uroflowmetry results, existence of PVR, in prediction of the surgical treatment outcome or if we think that the findings can change the choice of treatment.
