Urodynamic evaluation of surgical and endoscopic treatment of benign prostatic hyperlasia

Eighty eight patients suffering from outlet obstruction due to BPH were included in this study and divided into four groups: I open prostatectomy [TVP], II transurethral resection [TURP], III electrovaporization [TUEVP] and IV electrovaporesection [TUEVR]. All groups were age matched and had insignificant difference in means of prostatic size determined by TRUS. Patients with preoperative indwelling catheters were analyzed separately. Significant improvements were achieved in all groups in postoperative follow up of AUA symptom score in comparison with the baseline data. AUA score was significantly higher in TUEVP than in other groups during the first and third month visit. Detrusor instability was considerably reduced from 44.4%, 45.4%, 3.7% and 41.7% to 12.5%, 15.8%, 26.6% and 13.3% after relief of outflow obstruction in the four groups. However, this reduction was not statistically significant. Also, the degree of reduction in TUEVP was less than in the other groups. Other urodynamic parameters as low compliance, maximum flow rate, opening detrusor, detrusor pressure at maximum flow and volume of residual urine have significantly been improved after treatment without significant difference in the degree of improvement between the four groups
