In fact, the "diseased" kidneys themselves rarely cause pain. Most often, kidney pain is associated with urolithiasis. It is important not to miss the chronic expansion of the renal pelvis, leading to kidney degradation.
Often we identify painless, but dangerous changes in the walls of the bladder (polyps, asymptomatic malignant tumors of small sizes). We clearly see the discharge of urine from the ureter into the bladder. We do a dopplerography of the kidney vessels. We give consultations to the patient and doctors of related specialties.
