Введение. Кислотность (pH) мочи является одним из ключевых показателей, позволяющих оценить активность процессов литогенеза при мочекаменной болезни (МКБ). pH мочи, с одной стороны, является одним из значимых маркеров, сигнализирующих о наличии патологических изменений как в организме в целом, так и в мочевыделительной системе в частности. С другой стороны, pH мочи остается одним из ключевых параметров, регулирующих состояние мочевыделительной системы, определяющих тип метаболических литогенных нарушений при МКБ.

Целью данной работы стало изучение влияния pH мочи на образование мочевых камней различного химического состава и на уровень экскреции с мочой основных камнеобразующих веществ.

Материалы и методы. В исследовании были изучены данные 708 пациентов (303 мужчины и 405 женщины) с диагнозом МКБ. Всем пациентам выполнялся биохимический анализ крови, биохимический анализ суточной мочи, определение химического состава мочевого камня.

Результаты исследования. Частота встречаемости мочевых камней, состоящих из мочевой кислоты, снижается по мере роста показателей pH мочи с 42,3% (pH1) до 2,6% (pH8) (р=0,0000004). Максимальный уровень экскреции мочевой кислоты с мочой был зафиксирован в диапазоне pH мочи равном 5,6-5,9 (pH4) и составил 3,814 ммоль/сут. Частота встречаемости кальций-оксалатных конкрементов возрастала в интервалах pH 5,1 – 5,9 и 6,1 – 6,5. В интервалах pH 5,6 – 6,1 и 6,5 – 9,0 было зафиксировано резкое снижение частоты встречаемости кальций-оксалатных мочевых камней. Максимальный уровень экскреции кальция с мочой был зафиксирован при pH мочи 5,6-5,9 Распространенность карбонатаптитных мочевых камней увеличивается при росте показателей pH мочи. Данная тенденция прослеживается особенно четко в интервалах pH мочи 5,6 – 6,5 (с 23,0% до 50,8% соответственно). Самый высокий уровень фосфатурии (29,149 ммоль/сут), наблюдался при показателях pH мочи 5,6-5,9. В интервалах pH мочи 6,6 – 9,0 наблюдался резкий рост встречаемости струвитных конкрементов (19,3-36,8% соответственно) (р=0,00004).

Выводы. Показатель pH мочи является одним из основных факторов, влияющих на литогенез при МКБ. При проведении метафилактики особенно важно следить за цифрами pH мочи и при необходимости корригировать данные параметр.
