Clinically, bilateral hydronephrosis is serious, as it can lead to expansion of the renal pelvis. Long-term bilateral hydronephrosis can compress the renal parenchyma, leading to the development of chronic obstructive nephropathy, and thus cause chronic renal failure. Additionally, because urine cannot be expelled from the body in a timely manner in bilateral hydronephrosis, it is easy to combine with bacterial infections, which can lead to acute pyelonephritis. Patients may experience chills, fever, and severe back pain, as well as hematuria and general fatigue. Therefore, it is essential to identify the cause of bilateral hydronephrosis and treat it based on the nature of the hydronephrosis. Usually, the causes of bilateral hydronephrosis are related to stones, but tumorous diseases, bladder stones, or urethral strictures are also common causes.

How is hydronephrosis treated?

The treatment of hydronephrosis often requires surgery. Decisions about diagnosis and treatment plans should be based on clinical symptoms, the duration of the obstruction, the location of the obstruction, and whether there is an infection. Since hydronephrosis is typically caused by a pathological factor that blocks the ureter, surgery is often necessary to remove the obstruction in order to address the hydronephrosis and prevent further damage to kidney function. The principle of the surgery is that if the obstruction is minor, a simple corrective surgery may suffice. However, if the dilation of the ureter and renal pelvis is very significant, a reanastomosis of the ureter and renal pelvis might be needed.

How to relieve nausea caused by hydronephrosis?

Hydronephrosis with nausea can be caused by various reasons, so alleviating nausea symptoms requires specific analysis based on the specific cause. Patients with hydronephrosis often seen in hospital beds are mostly those with ureteral stones. When the stone is lodged in the ureter, the patient will experience an obstruction of urine outflow, leading to hydronephrosis. Moreover, a stone stuck in the ureter can cause renal colic, manifested as back pain, and may also be accompanied by symptoms of nausea and vomiting. In such cases, treatment methods depend on the size of the stone; if the stone is relatively small, it can often be passed naturally with increased water intake and conservative treatment. If the stone is large, it generally requires surgical removal. Hydronephrosis can also result from prolonged obstruction leading to impaired kidney function and uremia. In these situations, it's usually necessary to promptly relieve the urinary obstruction, maintain urethral patency, and, if the patient has elevated blood creatinine levels, employ dialysis or other methods to bring creatinine back to reasonable levels.

Hydronephrosis should see which department?

Hydronephrosis should be treated at a formal hospital's department of urology. Hydronephrosis is due to some factor causing urinary tract obstruction, potentially seen in urological conditions such as stones, tumors, congenital abnormalities of the ureter, and other causes. These lead to the kidney producing urine that cannot be properly expelled. Dealing with this condition often requires intervention by the urology department, as hydronephrosis typically necessitates surgery. In early stages, patients may need to adopt corresponding methods to address the specific causes. For instance, patients with stones might need extracorporeal shock wave lithotripsy, and open surgery might also be necessary; deformities of the ureter might need corrective surgery. These surgical treatments need to be performed in the urology department.

Will hydronephrosis cause facial swelling?

In cases of hydronephrosis, it is not certain whether facial swelling will occur. Since the human body has two kidneys, the kidneys have strong compensatory capabilities. Even if one kidney is completely damaged, if the other kidney remains healthy, the remaining kidney can still perform the function of two kidneys. It can ensure sufficient excretion of water and metabolic waste. When water is sufficiently excreted, swelling should not occur. However, if both kidneys are affected by hydronephrosis, or if the opposite kidney also has problems, then the ability of the kidneys to excrete water may decrease. With both kidneys having issues, it can lead to poor and insufficient water excretion, consequently causing swelling, such as bilateral eyelids, facial areas, and both ankles.
