Pregnancy is the natural state of a healthy woman, but bearing a child entails the appearance of some pathological phenomena in a pregnant woman. For example, increasing the size of the uterus leads to compression of the ureters, which in turn causes a pathological condition of the kidney, called hydronephrosis.
Why are the ureters so easily subjected to compression during pregnancy? The fact is that during this period in the female body hormonal changes occur that adversely affect the ability of the muscles of the urinary tract to contract normally and move the urine from the kidneys to the bladder. As a result, the ureter and renal pelvis expand, which is more pronounced on the right side. This is hydronephrosis during pregnancy. It occurs in almost 90% of pregnant women.
Signs of hydronephrosis during pregnancy
Hydronephrosis during pregnancy develops gradually and almost asymptomatically. Sometimes pregnant women complain of pain in the right side or in the back. If hydronephrosis is bilateral, a woman can stop urinating altogether.
Sometimes hydronephrosis is complicated during pregnancy by pyelonephritis - inflammation of the kidney and the defeat of the entire cupping and pelvic system. In these cases, there is a general and specific symptomatology - weakness, temperature, pain in the side and back, a change in the color and transparency of urine, the appearance of fetid odor of urine, the amount of which is reduced.
The uterus during pregnancy acquires large sizes by the 20th week. Expansion of renal pelvis and ureters is usually detected in the 3rd trimester with ultrasound examination of the kidneys. If the infection also joins, the clinical analysis of blood and urine shows changes - correspondingly an increased number of leukocytes in the blood and leukocyturia and bacteriuria in the urine.
Treatment of hydronephrosis in pregnancy
Hydronephrosis during pregnancy usually does not require special treatment, even though after the birth the ureters and the renal pelvis may remain extended for another 6-12 weeks. If there is severe pain syndrome, anesthetics and antispasmodics may be taken or an epidural catheter placed. In the most severe cases, percutaneous drainage is established to prevent rupture of the kidney and urine outflow.
It should be remembered that any medicinal preparations are extremely undesirable for the unborn child.
Hydronephrosis during pregnancy, as a rule, has a favorable prognosis.
