Introduction: Bladder outlet obstruction (BOO) in men is traditionally linked to the prostate. Urodynamics with pressure flow studies remain the gold standard for diagnosing BOO and other voiding and storage abnormalities. Study had planned to measure various parameters of bladder dysfunction by using Cystometry in patients of Prostatism and to find out correlation between PVR measured by two different techniques i.e. Cystometry and Ultrasonography, if any. Methods: This was observational study conducted from 2010 to 2012 in patients visiting Rural Medical College, Loni. Total 75 patients with age> 50 year and IPSS > 19 having symptoms of Prostatism were included in the study. Patient detailed history was taken with recording of USG findings and simple cystometry procedure was performed to measure various parameters like Bladder capacity, postvoid residual volume of urine (PVR) and Urge capacity and repeted 2 weeks after operation/ catheterisation. Results: By applying Chi-square test there is a significant association between post void urine in USG and Cystometry (i.e. p < 0.05). By applying Student’s Paired ‘t’ test there is a highly significant decrease in post void urine before and after 2 weeks operation / Catheterization (p < 0.01). And there is a highly significant increase in urge (p < 0.01) and only significant increase in Capacity before and after 2 weeks operation / Catheterization (p<0.05). Conclusion: Simple cystometry can provide useful information for accurate diagnosis, management plan or for prognosis purpose to urosurgeons or urologists. Further studies involving larger number of patients are necessary to determine the optimal role of formal urodynamics in the elderly.
