Hydronephrosis leading to kidney shrinkage indicates that the condition has persisted for a long time. Long-term hydronephrosis places significant pressure on the kidneys, which in turn compresses the kidney tissues causing tissue shrinkage. The destruction and shrinkage of tissues result in the kidneys' inability to function properly, leading to azotemia. Patients will experience chronic kidney failure, a situation that is difficult to reverse. Even if surgery is performed to relieve the obstruction and allow urine to be excreted, the damaged kidney tissue cannot regenerate. Therefore, it is still necessary to relieve the obstruction as soon as possible to avoid further damage to the remaining kidney tissue. For patients who have progressed to uremia, it may be necessary to consider hemodialysis or peritoneal dialysis, or undertake a kidney transplant to sustain life.

How is hydronephrosis detected?

The kidneys have a very strong compensatory ability. In the early stages of hydronephrosis, the amount of fluid may not be large, or the duration may not be long, and usually, the patient may have no symptoms. Hydronephrosis is often discovered during health examinations or through ultrasound or CT scans performed during hospital stays. Of course, if the hydronephrosis persists for too long and the volume is very large, the patient can gradually feel discomfort or a distended sensation in the lower back or upper abdomen. Moreover, if the hydronephrosis is caused by kidney stones, the patient often experiences severe back pain, and there might even be visible blood in the urine. Hydronephrosis can also lead to symptoms of urinary tract infections such as frequent urination, urgent urination, and painful urination. Prolonged hydronephrosis can lead to a decline in kidney function, resulting in symptoms like fatigue, loss of appetite, and poor overall health. Therefore, it is crucial for patients to undergo regular ultrasound examinations of the kidneys to detect hydronephrosis early.

How to relieve pain from hydronephrosis

Hydronephrosis accompanied by pain is generally caused by kidney stones lodged in the ureter leading to renal colic, and the stones in the ureter can cause urinary obstruction, thus presenting as hydronephrosis. To alleviate the pain in such cases, treatment methods are chosen based on the size of the stone. If the kidney stone is relatively small and estimated to be able to pass by itself into the bladder, temporary use of pain relief medication can be administered for symptomatic treatment, along with medication that dilates the ureter to expand its diameter, facilitating the expulsion of the stone. If the stone is large and predicted not to pass on its own, temporary symptomatic treatment with pain relief medication can be used. Meanwhile, after completing preoperative examinations, surgery can be performed to remove the stone, which can also completely alleviate the pain symptoms.

Hydronephrosis should be seen by the Urology Department.

Hydronephrosis requires consultation at the urology department of a formal public hospital. Hydronephrosis refers to the situation where urine produced by the kidneys cannot be smoothly excreted. The primary reason is usually due to obstructions in the urinary tract below the kidneys, such as in the ureter or bladder. Obstructive factors primarily include stones, tumors, prostate enlargement in men, scarring or adhesions in the ureter, or inadequate ureteral motility, among others, often necessitating urologic intervention. These obstructive factors usually require surgical removal, such as using ultrasonic lithotripsy for stones or direct surgical intervention, thus necessitating a visit to urology.

What tea to drink for hydronephrosis

Before hydronephrosis is adequately treated and before the obstruction in the urinary system is resolved, in areas such as the renal pelvis and calyces where there is fluid accumulation, it is advised that patients should not drink tea and should try to reduce their fluid intake. This is because the fluids cannot be excreted through the kidneys, and drinking large amounts of water at this time could worsen the obstruction and may also lead to edema. Therefore, patients are advised not to drink tea until the hydronephrosis is resolved. Once the causes of urinary tract obstruction, such as urinary system stones or tumors, have been removed, patients can increase their water intake, but it is still recommended not to drink tea because tea contains considerable amounts of oxalate, which can lead to the recurrence of kidney stones.

Is hydronephrosis of both kidneys serious?

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.
