Mainly depends on what causes hydronephrosis. The main reasons are as follows: intraluminal obstruction (nephroureterolithiasis, tumor, PUJ stenosis, etc. ) 2 Ureteral peristalsis rhythm disorder 3. External compression (retroperitoneal fibrosis ... There are many reasons for hydronephrosis, and the obstructive position of bilateral hydronephrosis is generally low. Therefore, it is mainly to relieve stones, so it is important to look at specific reasons for serious laxity. Right hydronephrosis is a kind of less serious nephropathy. But if it is not treated in time, it will be very serious. Urinary system is a continuous pipeline system from kidney to urethral orifice. The discharge of urine depends on the patency of urinary tract and normal urination function. The stenosis or obstruction of the pipeline in any part of the urinary tract and the normal dysfunction of neuromuscular will eventually lead to hydronephrosis, dilatation, thinning of renal parenchyma and decline of renal function. If there is bilateral obstruction, the consequences of uremia will be very serious. There are many reasons for urine flow obstruction. It can be congenital, such as ureteropelvic junction stenosis, urethral valve, horseshoe kidney, acquired diseases such as calculus, tumor, prostatic hyperplasia, bladder neck contracture, etc. It can also be obstruction caused by extraurethral fibrous band or tumor, such as retroperitoneal fibrosis and lymphoma. It may also be a neuromuscular disorder of urethra, such as megaureter. Obstruction can be divided into acute and chronic. Acute obstruction makes the kidney completely lose its function in a short time. But hydronephrosis is not obvious. Chronic obstruction can make hydronephrosis exceed 1000 ml. Once hydronephrosis is complicated with infection, if the obstruction is not removed in time, the infection is difficult to cure, and the infection accelerates the destruction of the kidney, forming a vicious circle and even forming pyonephrosis. Symptoms of primary disease, such as stone pain, tumor hematuria, dysuria, etc. It's a pain in the waist on one side of hydronephrosis. Complex infections are chills and fever. Purulent urine Cystic mass in the affected waist. Chronic renal insufficiency and uremia caused by bilateral obstruction. Hello, there are many reasons for hydronephrosis, different pathogenic reasons, different treatment principles and different curative effects. The common cause of hydronephrosis is urinary calculi. If it is hydronephrosis caused by ureteral stone obstruction, the treatment effect is better, and if it is kidney calculi, the treatment effect is worse. If it is a tumor, renal insufficiency is different. The treatment of tuberculosis is different. Drugs are only an auxiliary means, and it is difficult to be cured by drugs. Hello, hydronephrosis is not serious if it is treated correctly, but injection can't cure it. Processing method: 1. Local treatment: For the lesions at the obstruction site, it can be solved by local treatment, such as adhesion separation, fiber band cutting, vascular transposition anastomosis, stone removal, etc. Local ureter has been caused by local compression for too long. This segment of ureter should be resected and anastomosed. 2. If obstruction has caused severe hydronephrosis, fistula drainage should be performed first. 3. Plastic surgery: the key points that plastic surgery must master: ① pyeloplasty at the lowest point of the renal pelvis. ② The ureteropelvic anastomosis should be funnel-shaped. ③ The surrounding fibers, adhesions and scar tissues should be removed during repair, but the blood supply should not be damaged. ④ Remove the redundant renal pelvis wall and maintain a certain renal pelvis tension. If the hydronephrosis is too large, the thin renal cortex can be folded inward and fixed to reduce the internal volume of the kidney. ⑤ To reduce the leakage of urine at the anastomotic site, double pigtail catheters can be placed. In order to avoid scar fibrosis caused by urine leakage, hemolysis and congestion around the anastomosis, a negative pressure suction tube can be placed outside the anastomosis for adequate drainage. ⑤ There are many methods of plastic surgery, but at present, considering the etiology and pathology, it is considered that it is better to remove the diseased segment and anastomose it.
