Abstract: Objective To evaluate the effect of intracavitary retrograde dissection during transurethral vaporization resection of the prostate (TUVRP). Methods The efficacy of intracavitary retrograde dissection of the prostate with PK bipolar generation was evaluated in 260 cases in view of the volume of intraoperative bleeding, operation time, safety and postoperative bleeding, catheterization time and prognosis in comparison with the results of exclusive use of TUVRP. Results Intracavitary retrograde dissection of the prostate provided good operative view as compared with conventional TUVRP. Conclusion Intracavitary retrograde dissection is a practically feasible procedure for benign prostatic hyperplasia.
