Summary
Transurethral thermotherapy caused significant prostatic tissue damage, including microabscesses and nerve fiber loss, in patients undergoing prostatectomy. Histological analysis revealed necrosis and vasculitis in the prostate.
Area of Science:
- Urology
- Pathology
Background:
- Transurethral thermotherapy is a treatment for benign prostatic hyperplasia.
- Understanding its pathological effects is crucial for patient management.
Purpose of the Study:
- To evaluate the histological and immunohistochemical changes in prostatic tissue following transurethral thermotherapy.
Main Methods:
- Histological and immunohistochemical examination of prostatic specimens from 10 patients treated with transurethral thermotherapy and 2 controls.
- Microscopic analysis focused on tissue damage and nerve fiber integrity.
Main Results:
- Microscopic examination revealed microabscesses, epithelial necrosis, and vasculitis in prostatic tissue up to 2 cm from the urethral lumen.
- Immunohistochemical staining demonstrated damage and disappearance of nerve fibers.
Conclusions:
- Transurethral thermotherapy induces significant pathological changes in prostatic tissue.
- Nerve fiber damage is a notable consequence of this treatment.
