It is not recorded how often camels urinate, but they urinate less than most mammals.
Sources suggest that camels even sweat efficiently. Not only do they perspire at a lower rate than we do, their sweat evaporates beneath their fur for better cooling. When standing still or resting, camels often face the sun to reduce the amount of body surface area directly exposed to the sunlight. They also seek out shade and stand in each others' shadows when traveling in caravans.
A camel can resist 17 days without drinking under a scorching heat. To resist the lack of water, the camels have several means of adjusting to the situation. Their body temperature varies depending on the environment: in the cooler morning is of 34°C, whereas during the hot afternoon it goes up to 40-41°C.
The kidney function is regulated depending on the water availability: they produce 7 liters of urine when water is abundant, and 500 g when it does not drink for days. When thirsty, transpiration is reduced towards zero.
