What are the causes of hydronephrosis with ureteral stones?

The main cause of hydronephrosis with ureteral stones is the obstruction of the ureter by stones, which is often related to factors such as genetics, environment, bad living habits and abnormal urinary system function.

Genetic factors are an important basis for the occurrence of the disease. If there is a history of urinary stones or metabolic abnormalities in the family, the risk of disease will increase significantly. Environment and eating habits also play a key role. Long-term drinking of water containing high calcium and high oxalate, and excessive intake of protein and salt will cause supersaturated minerals in the urine to precipitate and form stones. Insufficient water intake leads to concentrated urine, long-term urine retention, and sedentary habits will also increase the risk of urinary stones. In terms of physiological factors, if there is infection in the urinary system, congenital or acquired malformations, such as ureteral stenosis, it will cause urine excretion obstruction. When stones fall into the ureter and block urine flow, urine is forced to accumulate in the kidneys, causing hydronephrosis. Certain metabolic diseases (such as hyperparathyroidism, gout) and urinary tract infections are also closely related to the occurrence of stones and hydronephrosis. Long-term bed rest after severe trauma may also aggravate the tendency of stones due to bone decalcification.

To prevent hydronephrosis with ureteral stones, you should drink plenty of water (2-3L per day) to promote urine dilution and reduce the chance of stone formation; pay attention to your diet, avoid high oxalate, high salt, and high protein intake, and supplement calcium appropriately; exercise more to improve metabolic function and prevent urine retention. If you have symptoms of urinary tract infection or urinary system diseases, you should seek timely treatment to eliminate hidden dangers. Once you experience symptoms such as severe pain in the waist and abdomen, hematuria, and decreased urine volume, you should seek medical attention immediately and choose a reasonable examination and treatment path.
