Effects of open prostatectomy on uroflowmetry parameters on patients having benign prostatic hyperplasia

Abstract

Objective: to assess the effects of urinary flow rate/ uroflowmetry in patients with benign prostatic hyperplasia preoperatively and following open prostatectomy for three months post operatively. Materials and Methods: this presoectine was done department of urological surgery AlSader Teaching Hospital between March 2010 to March 2016. Fifty consecutive patients age range 50 years to 80 years, on clinically diagnosed of benign prostatic hyperplasia (BPH) were include in the study, preoperatively uroflowmetry is carried out followed by uroflowmetry post open prostatectomy, after first month, second month and third month. Result: Mean age 63.62 ± 6.75 years Uroflowmetry parameter among fifty patients before operation are found, mean voiding time 32.37 ± 19.19 seconds, mean flow time 28.57 ± 15.79 seconds, mean time to maximum flow 9.64 ± 6.65 seconds, mean maximum follow rate 7.60 ± 2.41 ml/sec, mean overage flow rate 4.41 ± 1.28 ml/sec and mean voided volume 165.54 ml. postoperative uroflowmetry was carried out after first month, second month and third month. The average of first three months of postoperative follow up uroflowmetry parameter obtained are, voiding time 27.64 ± 11.67 (P = 0.14) seconds, flowtime 25.72 ± 11.00 (P = 0.29) seconds, time to maximum flow 6.59 ± 0.79 (P = 0.05) seconds, maximum flow rate 27.24 ± 5.11 (P = 0.001) ml second, overage flowrate 13.48 ± 2.08 (P = 0.001) ml second, voided volume 240.32 ± 49.91 (P = 0.01) ml. Conclusion: We conclude that the effects of post prostatectomy all the obstructive uroflowmetry parameters return more or less towards normal levels. As well as excellent improvements in both obstructive and irritative symptoms was also observed.
