EFFICACY OF LASER COAGULATION AT PATIENTS WITH URINARY BLADDER LEUKOPLAKIA WITH THE DIODE LASER ON LAHTA-MILON

Abstract

AIM OF RESEARCH. Evaluation of efficacy and safety of urinary bladder leukoplakia laser coagulation by diode laser. PATIENTS AND METHODS. 137 female patients with urinary bladder leukoplakia were observed. They were performed cystoscopy, biopsy of modified mucous membrane area and laser coagulation of urinary bladder modified mucous membrane by diode laser with wavelength 810 mkm. In 103 patients modified mucous membrane area located in vesical triangle, in 10 patients mucous membrane modifying was under right ureteral orifice, in 8 – under left ureter orifice, 16 women had combined injury of bladder neck and posterior bladder wall. RESULTS. According to histological examination data following diagnosis were confirmed: at 121 patients (88%) – urinary bladder leukoplakia, at 16 patients (12%) – chronic cystitis. Several days after laser coagulation of urinary bladder modified mucous membrane all patients noted disappiarance of disuria, decrease of uriesthesia and its urgency. CONCLUSION. Advantages of diode laser usage are: significant reduction of necrotic zone, required effect may be reached at minor capacity measures, lack of hemorrhage, recovery without coarse cicatrix, slight tenderness. Laser radiation wavelength 0,81±0,01 mkm have optimal combination of features necessary for surgical treatment on soft tissues in water.
