Some changes may seem normal, but at this stage of the disease they may signal a complication that requires prompt response
If you have metastatic bladder cancer, the risk of kidney problems is higher, including acute kidney injury and advanced stages of chronic kidney disease.
One of the most common complications is a blockage of the ureters – the tubes that carry urine from the kidneys to the bladder. urinary. The tumor can obstruct the flow of urine, causing enlargement of the kidney, its damage and, in severe cases, even renal failure.
Preserving kidney function is particularly important. Healthy kidneys help remove harmful substances and excess fluids from the body, contribute to bone health, regulate blood pressure and participate in the production of red blood cells.
All these functions help the body remain as strong as possible for current and future therapies.
Ureter blockage does not always cause severe and sudden pain. However, some signs should be carefully observed:
blood in the urine;
changes in urination, such as more frequent urination, difficulty starting to urinate, or a feeling that the bladder is not completely empty;
pain in the kidney area, which can also feel like back pain;
frequent urinary tract infections;
increased blood pressure;
mild fever;
mixed;
pain between upper abdomen and back;
swelling of one or both legs.
Although some of these symptoms may be related to the disease itself, some signs require immediate medical evaluation. An example is the feeling that the bladder is full, but the person cannot urinate.
If the problem is detected in time, doctors can often restore the flow of urine by placing a ureteral stent, a thin tube that keeps the ureter open, or through a nephrostomy, which allows urine to drain directly from the kidney, Telegraph reports.
Keep an eye on fluid intake and output
One of the easiest ways to to protect the kidneys is to avoid dehydration.
It is often recommended to take about two liters of fluid per day, but the amount should be adjusted according to the doctor’s advice and the patient’s condition.
always keep a bottle of water nearby;
to convey the amount of liquids you consume during the day;
keep notes in a notebook or phone application.
You should also pay attention to urination: how often you urinate, how much urine is and if there are changes in its color.
Any unusual changes should be reported to the doctor.
The medical team usually regularly monitors kidney function with blood tests and imaging examinations, especially before starting therapies and during check-ups.
In defense of the kidneys and urinary tract, several specialists may be involved:
the oncologist, who directs the cancer treatment and adapts the therapy according to the function of the kidneys;
the urologist, who treats blockages and may place a stent or drain;
onco-nephrologist, specialist for kidney problems in patients with malignant diseases;
caregiver or a loved one, who can help with symptom observation, record keeping, and daily care.
Open communication and collaboration with the medical team are essential to detect problems as early as possible and to preserve kidney function as long as possible.
