How to understand that the renal pelvis is enlarged during pregnancy and how to treat
Hydronephrosis refers to such a pathological condition when a progressive increase in the renal pelvis is formed. This happens as a result of mechanical disorders of urinary retention and an increase in pressure in the calyx and renal pelvis is accompanied.
Stagnation of urine provokes an increase in pelvis and thinning of their walls, so the development of atrophy of the parenchyma in the kidney may begin. The renal pelvis is enlarged during pregnancy usually only on one side.
Causes of pathology
The main reasons for the development of hydronephrosis in pregnancy include the following:
- Pathological abnormalities in the bladder or urethra, as the formation of obstacles in these departments provokes the emergence of hydronephrosis.
- Changes in the ureters - their twisting, squeezing, kinks and other deformities. Changes in the ureter provoke the development of hydronephrosis on the affected side, which is often manifested during pregnancy.
- Inflammatory process in pelvic or retroperitoneal tissue.
- Education of stones in the renal pelvis or ureter. They interfere with the proper discharge of urine, and hydronephrosis is considered an early sign of the development of urolithiasis.
- Narrowing of the lumen in the ureter through connective tissue.
- Disorders of the urinary tract - hypotension in the ureters or pelvis of the kidneys, etc. Such processes cause a slowing of the peristalsis of the ureters, causing hydronephrosis in pregnant women.
Regardless of the cause of the disease, the enlargement of the kidney of the kidney during pregnancy is supplemented with a gradual disruption of urinary retention, stagnation of urine and, as a consequence, an increase in the size of the renal pelvis. Simultaneously, in the kidney there is an increase in blood pressure, blood flow is disturbed, filtration of the popula and atrophy of the parenchyma tissue are manifested.
Over time, the walls of the renal pelvis are strongly stretched under the influence of hydrostatic pressure, and their thinning occurs. Such a process contributes to the violation of the excretory function of this organ.
Symptoms of pathology
The chronic form of pathology can occur without clinical manifestations. An increase in the renal pelvis during pregnancy can provoke nausea with vomiting, drawing pains in the side. With the development of a violation of outflow of urine in the lower parts of the pain sensations are manifested in connection with the stretching of the walls in the bladder.
During pregnancy, most often women complain of dull pain giving to the inguinal zone or to the thigh. Less severe pain, similar to an attack of renal colic, is less common. Such pain can be manifested against the background of not passing weak painful sensations, giving to the region of the waist.
If a pregnant woman has a sore kidney, then for a mistake such pain can be confused with the threat of abortion or premature delivery. Often the pain is supplemented by delays in urination, and after the birth of the child the pain gradually subsides.
Diagnosis of the pathology of
If the renal pelvis is enlarged during pregnancy, the diagnostic process consists in examining complaints and collecting data from the medical history. The presumptive diagnosis is confirmed on ultrasound of the abdominal organs.
In the first stages, mild expansion of the renal pelvis is revealed. Subsequently, the cups are activated in the process, and the entire calyx-pelvis system in the kidney increases. At the terminal stage of pathology, the kidney is a formation similar to a large cyst.
To diagnose a disease in a pregnant woman, catheterization of the ureters is organized. In this case, the catheter is inserted into the pelvis, emptying it, and then a contrast agent is injected.
Treatment of pathology
In the development of hydronephrosis, the management of pregnancy will depend on how long a pathology has developed, during or before pregnancy, whether additional infections are present, and whether normal kidney function remains.
If hydronephrosis first appeared during pregnancy, then it can be preserved except in cases of acute forms of the disease. The infection is treatable. Painful sensations can be alleviated at the knee-elbow position of the body. Such signs carry a diagnostic value.
If hydronephrosis began to develop before pregnancy, the doctor can raise the question of its artificial interruption. The decision should be made in a hospital and only after a full examination of the possibilities of kidney function, the presence of infections, and also if the cause provoking the development of hydronephrosis is taken into account.
