The right kidney, the Meng calyces, dilated the effusion, and the ureter was not visualized.

How long has the surgery been done and what kind of surgery has been done. Some patients may not recover immediately after surgery due to a large amount of fluid accumulation before surgery, and some may take half a year, a year, two years or more to slowly retract; There are also patients who may have another stone blockage, but your ureters are not visualized after a renal pelvein venography, and if the ureters are unobstructed or the stones are not blocked, the ureters should be visualized, and it may be a ureteral problem, but whether it is caused by ureteral stones or other reasons needs to be further examined and confirmed. If renal pelvis venography cannot confirm the diagnosis, retrograde imaging or even exploratory ureteroscopy can be done.

Severe hydronement in the kidneys can seriously affect kidney function and must be diagnosed early**.

It is very likely that the right side is blocked, and if there are no stones, it is necessary to rule out whether there is a stenosis of the right ureteroperoperal junction.

First of all, I should do a right ureteral retrograde angiogram, and if possible, I should do a CTU, and I should do ECT to evaluate the function of the right kidney.

It is estimated that the time of your hydrops is not short, and if the right kidney is visually imaging, it is estimated that it is still functional, and it should be actively saved. Go for a retrograde imaging to judge**no.,And then according to the corresponding situation**.

Directly go to a retrograde imaging to judge**no, and then according to the corresponding situation**.

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 methods of causing hydronephrosis are different for different reasons, and I don't know what the specific condition of the patient is now, what causes it, and only by making it clear can we choose the appropriate method.

Finally, I hope the above can help you. I also wish the patient a speedy **!

The diameter is not more than 4mm, and the stone can be discharged, and the diameter is larger than 4mm, which can be minimally invasive, and the renal pelvis can be extracorporeal lithotripsy.

Problem analysis: Hello, your venography shows that there is hydronephral hyphralis on the right side, and the ureter is not shown, it is very likely that there are stones or space-occupying lesions at the renal pelvis, if the stone happens to be blocked at the renal pelvis, the urine cannot be discharged, which will lead to hydronephrosis, and the corresponding ureters naturally cannot be developed.

Advice: Your doctor should let you do retrograde pyelogram, the indication of this contrast is to further examine when the conventional contrast effect is not satisfactory, but it is more painful, I personally recommend that you consider doing a CT first, CT can check the size of the kidney, stones, hydrops and renal parenchymal lesions and renal parenchymal remaining, and can distinguish kidney cysts and hydronephrosis, so it is recommended that you communicate with your doctor in the file.
