What causes tuberculosis in one kidney and hydronephrosis in the opposite side?

Renal tuberculosis is common in hematogenous metastases of pulmonary tuberculosis. However, in general, tuberculosis on one side does not directly cause contralateral hydronephrosis, and obstruction should be considered first for contralateral hydronephrosis. There are the following possibilities:

1.The tuberculous kidney passes through the urinary system and infects the contralateral ureter, causing contralateral ureteral stricture and then contralateral hydronephrosis. 2.

Contralateral ureteral stones, obstruction causing hydronephrosis. 3.Compression of the outside of the contralateral ureter, causing obstruction followed by hydronephrosis.

The above possibilities are preferably defined or excluded by ultrasound. Intravenous pyelogram or retrograde pyelogram should be done if necessary.

Hydronephrosis is a symptom, and for patients, it is necessary to consider the possibility of urinary tract infection complicated by hydronephrosis, and the possibility of hydronephrosis needs to be paid attention to the possibility of stones and obstruction, and Western medicine needs to be carried out as soon as possible. In this case, there is no effect on traditional Chinese medicine**, and it is necessary to use surgery and drugs to fight infection**, and it is necessary to regularly review and understand your own situation.

1.Guard**.

1) Hydronephrosis is mild, the disease progresses slowly, and the renal function has reached a balanced and stable state can be observed, but the progress of hydronephrosis should be checked regularly.

2) Obstruction that can be relieved spontaneously, such as physiological hydronephrosis in pregnant women.

2.Surgery**.

1) Indications for surgery: progressive aggravation of hydronephrosis, obvious clinical symptoms, declining renal function, clear obstruction, and complications, which should be operated.

2) Principles of Surgery**:

Removal of obstructive disease causing hydronephrosis: if the stone is removed; Relieve compression of fibrous cords or vagus vessels; Prostatic hyperplasia can be resected or removed.

If there is severe hydronephrosis resulting in total loss of renal function on the affected side or severe infection of empyema, but the contralateral kidney is functioning well, nephrectomy may be performed.

If the kidney function of the affected side is very poor due to hydronephrosis, and the function of the opposite kidney is poor due to other diseases, or even uremia, the hydronephrosis should be performed first, and the renal function should be restored before further treatment of the obstruction.

Bilateral hydronephrosis, care should be taken to rule out the cause of lower urinary tract obstruction. Generally, the side in good condition is first, and then the side with serious condition is dealt with after the situation improves. A nephrostomy is usually done first.

Hydraucalyceae and infundibular obstruction are mostly caused by stones, and surgery is generally not necessary if there are no clinical symptoms.

The principle of plastic surgery, pay attention to the normal anatomical relationship of the renal ureter, keep the nephroureteral open drainage, and the anastomosis should be at the lowest part of the renal pelvis. Prevent inversion during anastomosis, and strive to have a funnel-shaped suture. During the repair, the fibrous tissue adhesion scar should be removed as much as possible so as not to damage the blood supply, and the surrounding adipose tissue should be appropriately retained to cover the surgical field.

Hydronephrosis ** Principles:1Removal of ** and removal of obstruction.

2.If the condition is too poor or complicated, percutaneous nephrostomy can be used to drain the kidney. 3.

In severe cases of hydronephrosis or empyema, nephrectomy is indicated if the contralateral kidney is functioning well. 4.If it cannot be surgically removed, a double "T" tube or stent tube will be placed.

5.The main purpose of medication is to prevent and control infection before and after surgery.

Why does tuberculosis in one side cause hydronephrosis in the contralateral side?

First, bladder contracture and contralateral hydronephrosis are both common late complications of renal tuberculosis; secondly, tuberculous cystitis invades the contralateral ureteral orifice, resulting in inflammation, ulceration, and fibrosis; In addition, bladder tuberculosis lesions and contractures often lead to narrowing or incomplete closure of the unaffected ureteral orifice; Eventually, intravesical pressure increases, leading to renal pelvis obstruction or bladder urine reflux.

Contralateral infection has been caused.

Caused by retrograde infection of the bladder.

1. Ectopic vascular fibrous cords;

2. High ureteral renal pelvis insertion;

3. Ureteral junction stenosis and valve;

4. Local ureteral tortuosity caused by membranous adhesions, 5. Congenital hydronephrosis of fibrous cords can also be caused by dynamic causes, such as segmental undynamic dysfunction. Secondary hydronephrosis is usually caused by other disorders of the urinary system.

Diet Increase energy intake, but in order to avoid increasing the burden on the kidneys with hydrops, it is not advisable to eat too many protein-rich foods. Energy intake is mainly based on carbohydrates and fatty foods.

If there is unilateral hydronephrosis, it is not necessary to limit the amount of water intake, and if there is bilateral hydronephrosis and renal dysfunction, the daily water intake should be limited.

That's right.

I hope it will be helpful to the majority of friends. Hydronephrosis should be a sign of serious kidney disease and must be taken seriously.

Suggestion: Hello, your situation is considered to be hydronephrosis caused by kidney stones, CT can see the stones, and of course magnetic resonance can also be seen, but from the perspective of saving money, it is not necessary.

If you find stones, you should mainly pay attention to drinking more water, exercising more, such as skipping rope, etc., and if you find white blood cells in the urine routine in the acute stage, consider anti-infection**, antispasmodic**, etc.

Hello friends. The passage of urine from the renal pelvis is blocked, causing increased pressure in the kidneys, dilation of the renal pelvis and atrophy of the renal parenchyma, called hydronephrosis.

The most important cause of hydronephrosis is ureteropelval junction obstruction. It is mainly caused by ureteral strictures, stones, tumors, prostatic hyperplasia, bladder neck contractures, etc.

Hydronephrosis** Principle:

1.Removal of ** and removal of obstruction.

2.If the condition is too poor or complicated, percutaneous nephrostomy can be used to drain the kidney.

3.In severe cases of hydronephrosis or empyema, nephrectomy is indicated if the contralateral kidney is functioning well. 4.

If it cannot be surgically removed, a double "T" tube or stent tube will be placed. 5.The main purpose of medication is to prevent and control infection before and after surgery.

Whenever possible, drugs that do not harm kidney function or have little damage are used.

Therefore, the method of causing hydronephrosis is different for different reasons, and I don't know what the specific condition of the patient is now, which is caused by the ridicule of the raft, and only by making it clear can we choose the appropriate method.

Kidney cysts do not go away on their own, and it is best to identify the cause of the fluid accumulation and treat it symptomatically.

1) Congenital obstruction** Segmental non-function: due to segmental muscle absence, hypoplasia or anatomical disorder at the junction of the renal pelveureters or upper ureters, the normal peristalsis of this ureter is affected, resulting in dynamic obstruction. If this lesion occurs at the entrance to the ureterobladder, a congenital megaureter is formed, with the consequence of renal and ureteral dilation and hydrops.

Intrinsic ureteral stricture: most occur at the ureteropelvic junction of the renal pelvis, and the stricture is usually 1 2 mm in size but can be up to 1 3 cm in length, producing incomplete obstruction and secondary distortion. Electron microscopy shows that there are excessive collagen fibers around and between the cells of the obstructed segment, and over time, the muscle cells are damaged, forming inelastic narrow segments dominated by collagen fibers, which hinder the transmission of urine and form hydronephrosis.

Ureteral twisting, adhesions, banding, or valve slings, which may be congenital or acquired, often occur at the ureteral junction and at the lumbar ureter, and account for almost 2 3 percent of children and infants. Ectopic vascular compression is about 1 3 and is an ectopic hilar vessel located anterior to the ureteropelvic junction. Others include farrier-shaped kidneys and obstructed kidney rotation during embryonic development.

High ureteral opening: It can be congenital, or it can be asymptomatic pelvic dilation due to peripelvic fibrosis or vesicoureteral reflux, resulting in a relatively upward migration of the ureteropelvic junction and no stenosis can be detected during surgery. Congenital ureteral ectopia, cysts, double ureters, etc.

b) Acquired obstruction Post-inflammatory or ischemic scarring leads to local fixation. Vesicoureteral reflux causes the ureters to twist and eventually form the renal pelveropelvic junction or ureteral obstruction due to periureteral fibrosis. New organisms such as tumors and polyps in the renal pelvis and ureters may be primary or metastatic.

Ectopic kidneys (migratory kidneys). Stone and traumatic and scar stenosis after trauma.

3) Obstruction caused by external lesions Obstruction caused by external lesions includes lesions of arteries and veins; pathologies of the female reproductive system; pelvic tumors, inflammation; gastrointestinal lesions; Retroperitoneal lesions (including retroperitoneal fibrosis, abscesses, hemorrhages, tumors, etc.).

4) Obstruction caused by various diseases of the lower urinary tract such as prostatic hyperplasia, bladder neck contracture, urethral stricture, tumors, stones and even phimosis, etc., will also cause difficulty in emptying the upper urinary tract and form hydronephrosis.

My son is born with a pipe that does not grow good water, and it shouldn't be a pipe problem when you are old, go to a good hospital for a careful examination!

Hydronephrosis is due to an obstruction of the urinary system that causes dilation of the renal pelvis and calyces, in which urine is retained. Because urine accumulates in the kidneys, the pressure increases, causing the renal pelvis and calyces to enlarge and the renal parenchyma to shrink. If the retained urine becomes infected, it is called infectious hydronephrosis; When kidney tissue dies due to infection.

Losing function, the renal pelvis is filled with pus, called pyometraphrosis or pyometra. The most important cause of hydronephrosis is the obstruction of the ureteral junction of the renal pelvis, once the hydronephrosis is complicated by infection, if the obstruction is not removed in time, the infection is difficult, and the infection accelerates the destruction of the kidneys, forming a vicious circle, and even forming pus kidneys
