Hydronephrosis is a pathological condition characterized by enlargement of the renal pelvis, which occurs as a result of obstructed urine flow. This pathology can develop at any stage of the urinary tract, from the kidneys to the bladder. In most cases, hydronephrosis is a secondary disease, developing as a result of mechanical obstruction, such as kidney stones, tumors, or strictures. This condition can lead to serious complications, including renal failure, and requires careful monitoring and treatment.
History of the disease and interesting historical facts
Hydronephrosis has been known to medicine for many centuries. In ancient Greek medicine, the disease was referred to under the term "urostasis". However, the first detailed studies of hydronephrosis began only in the 19th century. In 1856, the French surgeon Charles Sergent described the nephrectomy technique, which for the first time allowed the removal of the affected part of the kidney and thus solved the problem of hydronephrosis. In the 20th century, with the development of ultrasound research methods, early detection of this disease became possible. This contributed to an increase in the number of successful operations and improved prognosis for patients.
Epidemiology
Hydronephrosis occurs in varying degrees of prevalence throughout the world. According to the World Health Organization, the incidence of this condition is approximately 1 in 1000 newborns. One of the main causes of hydronephrosis in children is congenital urinary tract obstruction, and in adults - urolithiasis. Studies show that among patients who have undergone nephrectomy, up to 20% cases are associated with hydronephrosis. In women, the disease occurs more often than in men, which may be due to anatomical features.
Genetic predisposition to this disease
Some forms of hydronephrosis are hereditary and may be associated with certain genetic mutations. In recent years, mutations in genes such as PKD1 and PKD2 have been identified that are associated with polycystic kidney disease, which can lead to the development of hydronephrosis. Cases have also been identified in which patients have modifications in genes responsible for the development and maintenance of the structure of the urinary tract. Relevant studies have shown that the presence of previous pathology in the family increases the risk of hydronephrosis in offspring.
Risk factors for the development of this disease
There are several factors that contribute to the development of hydronephrosis:
- Urolithiasis - the presence of stones in the kidneys or ureters can cause obstruction and, as a result, hydronephrosis.
- Tumors - both malignant and benign neoplasms can lead to compression of the urinary tract.
- Congenital anomalies - pathologies of the development of the anatomy of the urinary tract can be the cause of hydronephrosis from an early age.
- Kidney injuries - mechanical damage can disrupt the normal flow of urine.
- Pregnancy - the enlarged uterus can put pressure on the ureters, causing temporary obstruction of urine flow.
Diagnosis of this disease
Initial diagnosis of hydronephrosis is based on clinical manifestations. The main symptoms include:
- Pain in the lower back or side area,
- Urination disorders (pollakiuria, dysuria),
- Dyspepsia and loss of appetite,
- High temperature and signs of infection.
Laboratory tests may include urine tests for blood, protein, and infection. Radiological methods stand out among others: ultrasound of the kidneys, CT, and MRI will allow visualization of an enlarged renal pelvis. Functional tests, such as radionuclide scintigraphy to assess kidney function, are also important. Differential diagnosis should be made with diseases that have similar symptoms, such as pyelonephritis, kidney tumors, and complications of urolithiasis.
Treatment
Treatment of hydronephrosis depends on the cause of the disease. In general, several approaches can be distinguished:
- Conservative treatment is aimed at eliminating the infection and maintaining kidney function. Antibiotics and anti-inflammatory drugs are usually prescribed.
- Pharmacological treatment may include diuretics to facilitate the flow of urine.
- Surgical treatment - the need for surgery increases in the presence of obstruction caused by stones or tumors. Methods can range from endoscopic surgery to nephrectomy.
- Additional methods include the placement of catheters or stents to improve urine drainage.
List of medications used to treat this disease
The main groups of drugs used to treat hydronephrosis include:
- Antibiotics (eg, amoxicillin)
- Anti-inflammatory drugs (ibuprofen)
- Diuretics (furosemide)
- Painkillers (paracetamol)
Disease monitoring
Regular monitoring of the patient's condition is critical to prevent complications such as chronopathic renal failure. Key monitoring steps include:
- Periodic ultrasound to assess the condition of the kidneys,
- Laboratory tests (urine analysis, blood for creatinine),
- Clinical observations for relapses.
The prognosis generally depends on the cause of hydronephrosis. If it is identified early and adequate measures are taken to treat it, the likelihood of a positive outcome is high. Complications include chronic renal failure and infections.
Age-related features of the disease
Hydronephrosis may manifest itself differently in different age groups. In newborns and children, it is most often associated with congenital anomalies of the urinary tract. In adults, the main causes are urolithiasis and malignant tumors. In older people, the risk of increased incidence is associated with a general decrease in organ functionality.

Advice from Dr. Oleg Korzhikov
Hydronephrosis is a serious disease that requires a comprehensive approach to diagnosis and treatment. The main thing to remember:
- If you experience symptoms such as persistent lower back pain or changes in urination, you should see a doctor immediately.
- Regular check-ups will help avoid serious complications.
- Maintaining kidney health includes giving up bad habits and eating right.
In conclusion, it should be noted that hydronephrosis is a serious disease that requires careful approach to diagnosis and treatment. Timely actions can significantly improve the prognosis and quality of life of patients.
