The optimal method choice and ways of surgical treatment improvement for patients with posttraumatic, inflamatory and obstructive strictures of urethra

The lack of consistent standardized approach and variety of suggested methods for strictures and urethra obliteration treatment are still complicated problems for the modem urology. In this article, we investigate surgical treatment methods of urethra strictures and obliterations, taking into account the aetiology, locafization, extension and intensity of spongiofibrosis. The method for estimation of optimal resection zone in anastomotic urethroplasty, fixation zones of buccal graft and flap, using transcapillary flow laser analyzer, is proposed. This will give the opportunity to improve the surgical treatment results for this category of patients.Отсутствие единого стандартизированного подхода и многообразие методик предлагаемых для лечения стриктур и облитераций мочеиспускательного канала остается многогранной проблемой для современной урологии. В статье рассматриваются способы хирургического лечения стриктур и облитераций уретры с учетом этиологии, локализации, протяженности, выраженности спонгиофиброза. Предложен способ оценки оптимальной зоны резекции при анастомотической уретропластике, зоны фиксации буккального графта и флэпа с применением лазерного анализатора капиллярного кровотока, что позволит улучшить результаты хирургического лечения этой категории больных

Изменения ультраструктуры и микроциркуляции стенки мочевого пузыря у пациентов с неинвазивными формами рака

Bladder cancer relapses are associated with diffuse pattern of neoplastic changes in the mucous layer of the bladder; treatment efficacy depends on the degree of structural alterations in the bladder wall.Materials and methods: for evaluation of microcirculation characteristics and structural alterations of mucous layer of the bladder we have used laser analyzer of capillary blood circulation («ЛАКК-01» produced by НПП «ЛАЗМА», Russia) and compact mobile optic tomograph (ИПФ РАН, Russia).Results: conducted researches have shown alterations affecting both epithelial and submucous layers with their microcirculatory bed in perifocal to bladder tumor tissues.Conclusions: complimentary application of laser Doppler flowmeter and compact mobile optic tomograph allows defining the type and extent of pathologic process in the bladder wall in superficial tumors and choosing optimal method of correction.
