Abstract
Introduction
Transurethral resection of the prostate (TURP) is regarded as the gold standard surgical treatment for benign prostatic hyperplasia (BPH). The completeness of TURP may be assessed indirectly by estimation of the weight of glandular tissue removed. This parameter is often lower than expected. Tissue vaporisation in the course of TURP could be a contributory cause.
Aim
To quantitatively evaluate tissue vaporisation occurring in the course of transurethral resection of the prostate and electrovaporisation of the prostate (EVAP) performed under experimental conditions.
Material and methods
The study was performed on 26 prostate glands removed during retropubic prostatectomy. Immediately following surgery all adenomas were halved and TURP or EVAP were carried out on both halves of each gland for period of 5 min. The amount of prostate tissue which vaporised during EVAP and TURP were calculated.
Results
The mean weight (± standard deviation) of the adenoma lost due to resection and vaporisation in the TURP group was 10.00 ±2.92 g and 4.26 ±1.59 g, respectively. The latter accounted for 30.10 ±7.71% of total prostate weight reduction. The mean prostate weight lost in the course of EVAP was 5.03 ±1.58 g.
Conclusions
The vaporisation significantly contributes to the prostate tissue loss occurring during transurethral resection of the prostate.
