Background: Open simple prostatectomy (OSP) remains a valuable surgical option for patients with benign prostatic hyperplasia (BPH) in developing countries, especially patients with significantly enlarged prostate. Uroflowmetry, a non-invasive urodynamic test, plays a key role in both pre-operative assessment and post-operative evaluation of such patients. This study examined the role of uroflowmetry in outcome measure following OSP and explores the clinical implications of these measures. Methods: Fifty patients who had open simple prostatectomy were recruited into the study. Each patient had uroflowmetry (Oakfield Flowmate 2, 2003). The Qmax in each patient was noted and documented. Results: 33 of the 50 patients (66%) studied were on urethral catheter pre-operatively. The mean preoperative Qmax of patients that were not on catheter pre-operatively was 6.4 ± 1.6 ml/s. Post-operatively, there was a marked improvement in uroflowmetry parameters: mean Qmax increased to 22.52 ± 5.16 mls/s (p < 0.001). The mean PVR reduced from 160 mls pre-operatively to 20 mls post-operatively. Conclusion: Open simple prostatectomy significantly enhances uroflowmetry outcomes in patients with benign prostatic hyperplasia, validating its role in the objective outcome measure following OSP.
