Hydronephrosis with nausea can be caused by various reasons, so alleviating nausea symptoms requires specific analysis based on the specific cause. Patients with hydronephrosis often seen in hospital beds are mostly those with ureteral stones. When the stone is lodged in the ureter, the patient will experience an obstruction of urine outflow, leading to hydronephrosis. Moreover, a stone stuck in the ureter can cause renal colic, manifested as back pain, and may also be accompanied by symptoms of nausea and vomiting. In such cases, treatment methods depend on the size of the stone; if the stone is relatively small, it can often be passed naturally with increased water intake and conservative treatment. If the stone is large, it generally requires surgical removal. Hydronephrosis can also result from prolonged obstruction leading to impaired kidney function and uremia. In these situations, it's usually necessary to promptly relieve the urinary obstruction, maintain urethral patency, and, if the patient has elevated blood creatinine levels, employ dialysis or other methods to bring creatinine back to reasonable levels.

Does hydronephrosis hurt a lot?

Hydronephrosis does not necessarily cause severe pain. If the hydronephrosis develops suddenly over a short period, it might cause intense pain, most commonly due to urinary system stones blocking the ureter, leading to hydronephrosis. At this time, the ureter may experience spasms, causing severe pain. However, if the hydronephrosis develops gradually, the patient's pain symptoms might not be pronounced. For example, insufficient motility of the ureter or some type of narrowing could lead to the accumulation of fluid. If this condition develops slowly and persists for a long time, the patient might not feel particularly uncomfortable, despite the hydronephrosis, and it may only be discovered incidentally during a physical examination.

symptoms of hydronephrosis infection

In cases of hydronephrosis, urinary tract infections are common, and these infections primarily manifest as pyelonephritis. The presence of fluid in the kidneys indicates that urine cannot be excreted smoothly, leading to an obstruction in the urinary tract. Therefore, bacteria can easily multiply in this area because normal urine, if it can be excreted smoothly, also serves to flush the urinary system, preventing the growth of bacteria. Thus, when fluid accumulates, pyelonephritis can easily occur, with the main symptoms being back pain and fever. If cystitis is also present, the patient will experience symptoms such as frequent urination, urgent urination, and painful urination. Hydronephrosis may be caused by issues such as urinary system stones or tumors, which can also lead to clinical symptoms like back pain and hematuria.

Is hydronephrosis scary?

Hydronephrosis is rather alarming, as it harms the body in two main ways: First, it creates increased pressure inside the kidneys due to fluid accumulation in the urinary system. This pressure can compress kidney tissue, and if not resolved, may lead to irreversible kidney damage and renal failure. However, if hydronephrosis formed in the short term is quickly addressed by clearing the urinary system, it typically has minimal impact on kidney function. Another aspect relates to the causes of hydronephrosis, some of which are complicated issues, such as bladder cancer, rectal cancer, or cervical cancer in females. These cancers can press on the ureter, leading to hydronephrosis. Other causes, such as urolithiasis or benign prostatic hyperplasia, are relatively easier to manage.

Kidney hydronephrosis atrophy symptoms

Severe hydronephrosis may cause kidney atrophy. The symptoms of the patient can be divided into two aspects: Firstly, hydronephrosis may cause some clinical symptoms, such as some patients may experience swelling in the lumbar and back area, and a decrease in urine output. Patients may suffer from spasms of the ureter due to obstruction of the urinary system, resulting in severe pain, and some patients may also have hematuria. On the other hand, the atrophy of kidney tissue caused by this hydronephrosis actually means the loss of kidney function. Patients may exhibit symptoms of renal failure, such as swelling of limbs, increased blood pressure, nausea, vomiting, loss of appetite, anemia, and other clinical symptoms.

Can you have sex with hydronephrosis?

Before the complete resolution of hydronephrosis, it is recommended that patients avoid sexual intercourse. This is because hydronephrosis indicates the presence of obstructive factors in the urinary system, causing urine to not be excreted smoothly. Urine accumulates within the urinary system, causing dilation of the renal pelvis, calyces, and ureter. If urine cannot be excreted, bacteria can easily ascend from the urethral opening into the urinary system, causing an inflammatory response. If patients engage in sexual intercourse during this time, bacteria at the urethral opening can easily be pressed into the bladder, ascending and potentially causing pyelonephritis or cystitis. Therefore, it is best for such patients to avoid sexual intercourse until the hydronephrosis has been thoroughly addressed.
