What to do if hydronephrosis causes pain during pregnancy

If hydronephrosis occurs after pregnancy, pregnant women will be particularly worried, fearing that the fetus in their belly will be harmed. At this time, they must remain optimistic and not be too nervous. If the pain caused by hydronephrosis is too severe, they can also find a suitable treatment method, which can alleviate their condition to a certain extent.

Surgical treatment of hydronephrosis should be performed early. Reasonable application of plastic surgery can correct abnormalities of the ureteropelvic junction and strive for a greater recovery of renal function. If the hydronephrosis is severe and the renal function is severely damaged, but the contralateral kidney is normal, hydronephrectomy can be performed.

The principle of surgery is to perform simple corrective surgery when the obstruction is mild and the renal pelvis and calyx dilatation is not serious; if the dilatation is obvious, the narrow segment of the disease and the over-dilated renal pelvis should be removed, and then anastomosis should be performed; if the condition is more serious, nephrectomy should be performed.

The treatment of bilateral hydronephrosis should be more cautious, and every effort should be made to preserve the kidneys. There are generally several situations:

1. Severe hydronephrosis on one side

One side is less severe: the severe side can be treated first. This can prevent renal insufficiency and increase safety for contralateral surgery after a successful operation. For the milder side, the surgical indications should be carefully determined and close observation should be performed if necessary.

2. Severe hydronephrosis on both sides

It can be treated in stages, but it is still better to treat the more serious side first.

3. Mild hydronephrosis on both sides

Careful analysis is required to determine the indications for surgery.

Patients often remain asymptomatic for a long time until they develop an abdominal mass and a bloating in the waist. The lumps are often discovered accidentally and usually have a cystic feel. The pain is usually mild or even completely painless. However, in cases of intermittent hydronephrosis (caused by ectopic vascular compression or renal ptosis), renal colic may occur, with severe pain radiating along the rib margin and ureter. It is often accompanied by nausea, vomiting, abdominal distension and oliguria. It usually eases within a short time or a few hours, followed by the excretion of a large amount of urine. Enlarged kidneys may be palpated during examination. If it is giant hydronephrosis, the tension may not be very high.

If hydronephrosis is complicated by infection, there will be pyuria and symptoms of systemic poisoning, such as chills, fever, headache and gastrointestinal dysfunction. Some patients have urinary tract infection as the initial symptom. Patients who do not respond well to urinary tract infection treatment must pay attention to the presence of obstructive factors. When the obstruction is severe, the inflammatory exudate cannot be excreted through the urine and there are no white blood cells in the urine, but in this case the local pain and tenderness are more obvious.

Enlarged hydronephrosis is more susceptible to trauma, and even minor injuries may cause rupture and bleeding. Leakage of urine into the retroperitoneal space or peritoneal cavity can cause severe reactions, including pain, tenderness, and systemic symptoms
