The proximal tubule is an elongated epithelial tubule that is connected to the wall layer of the renal capsule and has a reabsorptive and excretory role. The renal tubules are divided into three parts according to different morphological structures, distribution locations and functions; the proximal tubule, the fine segment and the distal tubule. The proximal tubule can be divided into straight and curved sections. The curved part, also known as the proximal tubule, is located in the cortical labyrinth and is highly coiled near the renal tubule. So what are the tests for proximal tubule involvement? Here is a brief introduction. The examination items of proximal tubular involvement 1, renal ultrasound examination is a medical examination item that patients with proximal tubular involvement are often exposed to when they visit the clinic. Generally speaking, different positions and detection pathways in the examination can be used to obtain more satisfactory sonograms. In clinical practice, it is widely used in the diagnosis of cardiology, gastroenterology, urology, and obstetrics and gynecology diseases. IndicationsPelvic effusion, renal cyst, polycystic kidney, renal tumor, renal cancer, renal stone have abnormal sonogram performance. 2. Hematuria to see if there are abnormal kidney function abnormalities. 3.Blood and urine routine, to see if there are abnormal urine and stool abnormalities. The function of the proximal tubule is obstructed reabsorption, so the absorption of the proximal tubule for the kidney directly affects the excretory function of the body, which seriously affects our daily life, so we should pay attention to more daily activities to enhance physical fitness is important to ensure a relaxed mood and normal sleep.
