Causes of female urethral dilation

Everyone's physical condition is different. The physical condition of female friends is inherently weak, not only housewives, but also professional women in the workplace. In this case, they will devote all their time to work, which will cause urethral dilatation. So let us understand the causes of female urethral dilatation.

main reason:

1. Ureteral tumor

Common benign lesions of ureteral tumors are ureteral polyps, and malignant lesions are ureteral cancer. Both ureteral tuberculosis and ureteral tuberculosis cause ureteral dilatation above the lesion, hydronephrosis and renal dysfunction. The characteristic of ureteral tumors is that most patients present with painless hematuria; excretory and retrograde urography show filling defects at the ureteral lesions, dilation of the ureter above the lesion, and smooth mucosa, unlike ureteral tuberculosis, where the lesion is extensive and presents worm-eaten or beaded changes. The ureter may show S-shaped changes due to water accumulation, but there is no stiffness; the examination of exfoliated cells in the urine may be positive.

2. Ureteral inflammatory stenosis

It is caused by nonspecific infection, often secondary to pyelonephritis and cystitis. Excretory and retrograde urography shows localized stenosis of the ureteral inflammation site, ureteral dilatation and hydronephrosis above the stenosis, which should be differentiated. However, there were no destructive changes in the renal pelvis and calyces; urine bacterial culture was positive but Mycobacterium tuberculosis culture was negative. Cystoscopy showed edema and congestion of the bladder mucosa, but no tuberculous nodules, granulation wounds or ulcers. Its clinical manifestations are characteristic of ureteritis, with paroxysmal colic due to ureteral peristalsis. Ureteral tuberculosis is characterized by frequent urination, urgency, and pain during urination.

3. Ureteritis

The cause of periureteritis is unknown. The lesion occurs as proliferation of retroperitoneal fibrous tissue, which surrounds one or both ureters. It is commonly found at the ureteropelvic junction and the iliac vessel bifurcation. However, it can also involve the ureters above the pelvis and even the kidneys because the fibrous tissue wraps around the ureters, causing ureteral stenosis, ureteral rigidity, and hydronephrosis. The two need to be differentiated. Periureteritis is rare, and there are less frequent urination, urgency, and pain when urinating. Excretory and retrograde urography show that the ureter is displaced to the midline and the lumen is narrowed, but the ureteral lumen is smooth without worm-like and beaded changes, and there are no destructive lesions in the kidney. Cystoscopy shows no tuberculous nodules, granulation wounds, or ulcers on the bladder mucosa. Urinalysis shows few pus cells and no rice-soup pyuria.

The above article gives you a detailed introduction to the causes of female urethral dilatation. I believe you have a preliminary understanding of it. Therefore, in daily life, if such symptoms occur, you should go to the hospital for examination in time.
