НЕИНВАЗИВНАЯ ДИАГНОСТИКА РАКА МОЧЕВОГО ПУЗЫРЯ МЕТОДОМ КРОСС-ПОЛЯРИЗАЦИОННОЙ ОПТИЧЕСКОЙ КОГЕРЕНТНОЙ ТОМОГРАФИИ (СЛЕПОЕ СТАТИСТИЧЕСКОЕ ИССЛЕДОВАНИЕ)

Whether cross-polarization (CP) optical coherence tomography (OCT) could be used to detect early bladder cancer was ascertained; it was compared with traditional OCT within the framework of blind (closed) clinical statistical studies. One hundred and sixteen patients with local nonexophytic (flat) pathological processes of the bladder were examined; 360 CP OCT images were obtained and analyzed. The study used an OCT 1300-U CP optical coherence tomographer. CP OCT showed a high (94%) sensitivity and a high (84%) specificity in the identification of suspected nonexophytic areas in the urinary bladder.Оценена возможность кросс-поляризационной (КП) оптической когерентной томографии (ОКТ) в выявлении раннего рака мочевого пузыря (РМП), выполнено сравнение ее с традиционной ОКТ в рамках клинических слепых (закрытых) статистических исследований. Исследованы данные 116 пациентов с локальными неэкзофитными («плоскими») патологическими процессами мочевого пузыря, получено и проанализировано 360 КП ОКТ-изображений. В работе использован КП оптический когерентный томограф «ОКТ 1300-У». КП ОКТ показала высокую чувствительность (94 %) и специфичность (84 %) в идентификации неэкзофитных подозрительных зон в мочевом пузыре

Pathogenetic Aspects of Treatment of a Chronic Cystitis

The analysis of mucosa's state of the bladder in treating the exacerbation chronicle cystitis in 67 women was made. The analysis was made with the use of the method of optical coherent tomography (ОСТ). Dynamic ОСТ was performed in 23 patients after antibacterial treat (after 2 weeks) and in the period of remission. It was 59 ОСТ examinations. After antibacterial treatment the pathologically unchanged mucosa was found in the form of thickening in interu-retericfold in Lieutands triangle, in the neck of urinary bladder. Sub mucosal layer was also think, the structure of fibers was destroyed. Both leucocytic and lymphocytic infiltration in the wall of the bladder was observed. The tissue which reflected the light signal was found in muscle structure in the period of remission. This correspond to fibrosis in the wall of the bladder. In the long process the atrophy of mucosa was found. Thus, pathogenetic therapy should proceed after decrease in expressiveness of clinical displays of diseas
