Abstract: Изобретение относится к медицине, а именно к урологии. Во внутренний просвет мочеиспускательного канала вводят ригидный уретероскоп до мочевого пузыря, по которому устанавливают мочеточниковый катетер Sh №4 в мочевой пузырь, далее ригидный уретероскоп извлекают, а затем ригидный уретероскоп вводят вновь в мочеиспускательный канал по имеющемуся там мочеточниковому катетеру до мочевого пузыря. По ригидному уретероскопу вновь устанавливают мочеточниковый катетер Sh №4 в мочевой пузырь, таким образом, повторяют манипуляции до тех пор, пока в мочеиспускательном канале не окажется 6-8 мочеточниковых катетеров Sh №4, которые фиксируют к крайней плоти полового члена или к уздечке. По истечении трех дней после калибровки мочеиспускательного канала возможна установка уретрального катетера или восстановление естественного мочеиспускания. Ригидный уретероскоп фиксируют к камере, а она через блок управления камеры дает изображение на монитор. Способ позволяет существенно повысить вероятность трансуретрального дренирования мочевого пузыря и позволяет избежать травматического повреждения мочеиспускательного канала. 1 з.п. ф-лы, 1 пр.
