Objective: To evaluate the curative effect of dissection for coalesce of prostate in treatment of bladder outlet obstruction (BOO) caused by benign prostate hypertrophy (BPH) with relatively small volume (less than 30 g).
Methods: Thirty-six patients of BOO caused by BPH with relatively small volume underwent dissection of prostate coalesce. Follow-up was conducted for 32 months (9 - 52 months). The values of international prostate symptom score (IPSS), maximum flow rate (Qmax), and postvoid residual volume (PRV) before and after treatment were measured and compared.
Results: The post-operative IPSS was 5.03 +/- 2.66, significantly lower than that before operation (14.19 +/- 5.35), the post-operative Qmax was (17.71 +/- 4.1) ml/s, significantly higher than that before operation [(6.19 +/- 2.14) ml/s], and the post-operative PRV was (8.53 +/- 4.78) ml, significantly lower than that before operation [(50.58 +/- 14.84) ml] (all P < 0.001).
Conclusion: Dissection of prostate coalesce is an ideal method in treatment of BOO caused by BPH with relatively small volume (less than 30 g).
