Immunohistochemical evaluation of the safety of transurethral electrovaporization of the prostate and its clinical results

Abstract

Short term follow up studies on transurethral electrovaporization (TUEVP) have shown a relative low morbidity over TURP. The use of high power current has been claimed as a source of possible damage on the neuronal structures surrounding the prostate.

The aims of our study were to assess longer follow up results as well as the safety of this technique.

Over an 18 month mean follow up period symptom relief remained relatively stable. Postoperative dysuria was detected in a higher percentage of patients and was seen for a longer period in comparison with previous reports.

Immunohistochemical staining performed using S-100 and NF monoclonal antibodies showed anatomical integrity of the prostatic neuronal fibres surrounding the vaporization edge.

In conclusion, although the effectiveness and safety of TUEVP are confirmed by the present study, the occurrence of a significant rate of long-lasting postoperative irritative symptoms must be taken into account.
