What causes hydronephrosis in pregnant women?

Maternal hydronephrosis is a common pregnancy complication, which refers to the accumulation of water in the kidneys of pregnant women during pregnancy. This condition can cause a range of health problems for the mother and fetus, so understanding the cause of hydronephrosis is important to preventing and treating the condition. One of the main causes of hydronephrosis is urinary tract obstruction. During pregnancy, the enlargement of the uterus puts pressure on the urethra, causing obstruction in the passage of urine. This obstruction can occur anywhere in the urethra, including the bladder neck, ureters, and renal pelvis. Blockage of urine can cause urine to accumulate in the kidneys, causing hydronephrosis. 200 Examples of Nutritional Recipes for Pregnant Women in Three Months Ultra-clear Full Color PDF There are many causes of urinary tract obstruction, including urethral stricture, urethral stones, urinary tract infection, etc. During pregnancy, due to the influence of hormones, the muscles of the urethra and bladder relax, resulting in increased resistance to urine discharge, thereby increasing the risk of urinary tract obstruction. In addition to urinary tract obstruction, another common cause of hydronephrosis in pregnant women is urinary reflux. Urinary reflux is the return of urine from the bladder into the ureters and renal pelvis. Under normal circumstances, the body\’s valve mechanism prevents the reflux of urine, but during pregnancy, due to the enlargement and compression of the uterus, this valve mechanism may fail, causing urine to reflux, which can lead to hydronephrosis. In addition, hydronephrosis in pregnant women may also be related to changes in hormone levels during pregnancy. Increased progesterone may lead to decreased urinary excretion, increasing the risk of fluid accumulation in the kidneys. In addition, the influence of hormones may also lead to changes in the structure and function of the kidneys, further increasing the possibility of hydronephrosis. Finally, hydronephrosis in pregnant women may also be related to the genetic factors of individual pregnant women. Some studies have found that some pregnant women have abnormal kidney development or other genetic factors that may increase their risk of hydronephrosis. To sum up, the main causes of hydronephrosis in pregnant women include urinary tract obstruction, urinary reflux, hormonal changes during pregnancy and genetic factors. Understanding these causes is important to prevent and treat hydronephrosis in pregnant women. If a pregnant woman develops symptoms of hydronephrosis, she should seek medical advice promptly and receive appropriate treatment. At the same time, pregnant women should also pay attention to maintaining good living habits, including regular urination, avoiding urine retention, maintaining appropriate water intake, etc., to reduce the risk of hydronephrosis.
