- Abstract
Introduction and Objectives. Urinary retention in women has often been considered to be caused due to neurologic or psychogenic disorders. In spite of extensive investigations sometimes the causes of urinary retention may remain unknown. The aim of this paper is to highlight the place of post-void residual urine (PVR) evaluation and the urodynamic diagnosis of voiding dysfunctions in women. Materials and Methods. We performed a retrospective study over a period of 3 years in Mures County Hospital, Clinic of Urology. In this study we included 47 women which presented the selection criteria (voiding symptoms, PVR confirmed by abdominal ultrasound, over 50 ml and the results of urodynamic investigations: uroflowmetry and pressure-flow study). Results. The mean age of the patients was 51,97 ± 16,07 SD (standard deviation) years old with wider extremities between 20 to 78 years old. The mean value of PVR was 140 ml (50-260 ml). The mean value of Peak flow rate (Q max) was 11,70 ml/s ± 6,82 SD. The mean value of detrusor pressure (Pdet) at peak flow was 70,07 ± 32,66 SD cm H2O in detrusor sphincter dyssynergia, 64,66 ± 33,32 SD cm H2O, in obstructed cases and 11,29 ± 5,63 SD cm H2O in cases with impaired detrusor contractility. The urodynamic diagnosis (pressure flow study) revealed detrusor sphincter dyssynergia in 14 cases, 11 with underactive detrusor, 14 with acontractile detrusor, 2 with obstruction due to genital prolapse gr III and IV, 2 with urinary retention post TOT and 4 with urethral stenosis. Statistical analysis demonstrated a correlation between the quantity of post void residual urine and value of Qmax (r = -0,32 and p = 0,02) and also the existence of PVR and diagnosis of impaired detrusor contractility, p = 0,02. Conclusions. Urinary retention in women is a condition that needs an adequate attention and a proper diagnosis protocol, in order to take into account the study of detrusor contractility. A significant post-void residual urine can be associated with an impaired detrusor contraction.
