!!!NEW!!! CLINICAL FORUM !!!NEW!!!
to make the quarterly livelier and more beneficial for doctors and scientists !!!

On June the 1st, 2021 VSJ launches a new discussion platform in the journal.

We invite all MIS surgeons to rapidly submit for publication:
- small forms describing unusual clinical situations related to their practice,
- short clinical comments relating to any publications in VSJ, including the clinical situations described above
- brief communications of original studies deserving fast publication
- your personal opinions as part of a larger discussion on the VSJ publication
- letters concerning the topics described above

Clinical Forum gives you a means of rapid presentation of your findings in the medical databases, scientific citations on the international forum, and also an Impact Factor!

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 γ 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.
