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.

Is hydronephrosis with hematuria serious?

Whether hematuria in patients with hydronephrosis is serious cannot actually be determined by the amount of blood in the urine. It is important to identify the cause and assess kidney function, because hydronephrosis can lead to serious consequences, mainly kidney failure. If the hydronephrosis persists for a long time, it can compress the renal cortex and cause kidney shrinkage, leading to chronic kidney failure. The dangers of hematuria mainly include: first, it may cause significant bleeding, leading to anemia. Second, this type of hematuria could be caused by certain conditions, such as bleeding caused by a tumor in the urinary system, which is quite serious. Whereas bleeding caused by urinary tract infections or urinary system stones, in terms of the nature of the cause, is not considered very serious. However, significant bleeding can also lead to severe anemia and even shock, which would be more serious.

What is the best treatment for hydronephrosis?

The so-called hydronephrosis often occurs due to some factor blocking the urinary system, causing urine to not be excreted normally. The most common cause is urinary system stones, but it can also be due to issues like tumors or benign prostatic hyperplasia. The treatment for stones depends on the size of the stone. Stones smaller than 5 millimeters in diameter can often pass naturally. If the stone is 7 to 15 millimeters in diameter, extracorporeal shock wave lithotripsy is typically used. If stones in the lower mid-ureter do not respond well to medication, retrograde removal under cystoscopy can also be performed. For some patients who have had a long-standing obstruction, renal function may already be impaired. If the obstruction cannot be relieved, surgeries such as creating a urinary diversion can be performed. This includes procedures like bladder fistulation, pyelostomy, or percutaneous ureterostomy, among others.

Does hydronephrosis cause pain?

Patients with hydronephrosis do not all experience pain. In fact, only a minority of patients experience pain. Hydronephrosis is caused by some form of urinary obstruction, such as urinary system stones, tumors, or problems like prostate enlargement, which prevent urine from being excreted smoothly. In this case, the accumulation of fluid can be a long-term, gradual buildup. Patients often adapt to the progression of the condition and do not exhibit obvious symptoms, especially in the early stages. However, some patients may experience pain, such as those with urinary system stones, or pain may occur when a tumor ruptures.

Will hydronephrosis cause facial swelling?

In cases of hydronephrosis, it is not certain whether facial swelling will occur. Since the human body has two kidneys, the kidneys have strong compensatory capabilities. Even if one kidney is completely damaged, if the other kidney remains healthy, the remaining kidney can still perform the function of two kidneys. It can ensure sufficient excretion of water and metabolic waste. When water is sufficiently excreted, swelling should not occur. However, if both kidneys are affected by hydronephrosis, or if the opposite kidney also has problems, then the ability of the kidneys to excrete water may decrease. With both kidneys having issues, it can lead to poor and insufficient water excretion, consequently causing swelling, such as bilateral eyelids, facial areas, and both ankles.

How is hydronephrosis caused?

The causes of hydronephrosis can be divided into congenital, acquired, and external factors. Among these, acquired causes are the most common, primarily referring to obstructions in the urinary tract, such as stones that block the ureter, leading to hydronephrosis, inflammation, or ischemic damage. Scarring of the ureter can also result in hydronephrosis. Tumors or polyps in the renal pelvis and ureter may also cause obstructions leading to fluid accumulation. External causes mainly include diseases of retroperitoneal organs, such as abscesses, bleeding, tumors in the retroperitoneum, and pelvic tumors, like rectal cancer. Congenital causes mainly involve intrinsic narrowing of the ureter, ectopic vessels causing compression, and high insertion of the ureter, which are less common.
