What is the cause of ureteral hypertrophy?

summary

Ureteral ridge hypertrophy is one of the clinical manifestations of bladder neck contracture. Ureteral ridge hypertrophy generally occurs in middle-aged and elderly women, which may be related to the decrease of estrogen level, atrophy of urethrovaginal epithelium, decreased resistance and repeated infection. Therefore, a small amount of long-term estrogen should be used. What's the cause of ureteral hypertrophy?

What is the cause of ureteral hypertrophy?

Most of them think that it is related to chronic inflammation. The pathological manifestations are that the smooth muscle of the submucosa of the neck is replaced by fibrous connective tissue, the bladder neck becomes pale, rigid and fixed, and the neck mouth becomes narrow. The appearance of bladder neck obstruction, that is, dysuria for a long time. Women, also known as "female prostate disease", are more common in middle-aged and elderly women. Male bladder neck contracture can occur simultaneously with benign prostatic hyperplasia. Therefore, the bladder neck should also be formed after prostatectomy, otherwise the symptoms of obstruction can not be relieved.

The main clue of diagnosis is dysuria. Therefore, we should ask the details of dysuria. During physical examination, pay attention to whether there are masses in bilateral renal areas, palpation and percussion, and whether the bladder is swollen. But the diagnosis of this disease depends on cystourethroscopy and X-ray examination. In short, the diagnosis of this disease is based on a long history of dysuria. Endoscopic X-ray examination, on the basis of excluding other obstructive lesions, grasps the characteristics of this disease, such as tight posterior urethra during instrument examination, neck protruding slightly into the bladder during cystography.

Dysuria, strenuous urination, segmented urination, crying in children, urine dripping, and sometimes reflexive urination. When combined with urinary tract infection, the above symptoms are more obvious. During physical examination, the bladder may swell in the lower abdomen, but it is not always obvious.

matters needing attention

Bladder neck contracture mostly occurs in middle-aged and elderly women, which may be related to the decrease of estrogen level, atrophy of urethrovaginal epithelium, decreased resistance and repeated infection. Therefore, a small amount of long-term estrogen should be taken for a long time. Pay attention to perineal hygiene. The hyperplasia of the posterior lip of the bladder neck was resected to the depth of the triangle. Avoid over cauterization to avoid scar stenosis again. Do not cut the neck sphincter too deeply to cause urinary incontinence. After the operation, the urethra should be dilated regularly until the urine line is thick and stable.
