Open Journal of Urology (OJU) , 2017, DOI: 10.4236/oju.2017.73008
Abstract: Aim: To determine whether bladder functions deteriorate with age. Methods: Data contained in electronic medical record (INFOMED?) were used in this institutional retrospective review. Analysis was done on the urodynamic studies in women over 18 years old conducted between May 2011 and November 2015. Patients with previous history of pelvic surgery or radiotherapy, neurological disease, vaginal prolapse greater than grade I, congenital urogenital malformations, urinary obstructive disease, diabetes, or the use of any medication that could interfere with bladder function were excluded from the analysis. The urodynamic parameters analyzed were the Maximum Cystometric Capacity (MCC), Voiding Volume (VV), Maximum Flow (Qmax), Bladder Compliance (BC), Detrusor Pressure at Maximum Flow (PdetQmax), Bladder Contractility Index (BCI), Bladder Voiding Efficiency (BVE) and Post-Void Residual Urine Volume (PVR). Patients were further stratified in five groups according to age (A—18 to 40; B—41 to 50; C—51 to 60; D—61 to 70; E—over 70 years old). Results: Out of 3103 urodynamic studies analyzed, 719 were eligible for the study. The average age of patients was 49.3 (+13.2) years old and in all evaluated parameters, statistically significant correlation between age and decline of bladder function was obtained (p < 0.05). Moreover, mathematical equations were presented to estimate the parameters values in relation to age. Conclusions: This study showed a decline in bladder storage function (reduction in MCC and BC) and in bladder emptying function (reduction in Qmax, PdetQmax, VV, BCI and BVE with an increase in PVR) with age.
