Bladder distention
Introduction
Introduction In the short period of acute urinary retention, the bladder fills up, and the bladder expands rapidly and becomes a tension-free bladder bloating and bulging, and the urine is urgent, and it is not possible to urinate on its own. He had normal urination and no history of dysuria. There is a large amount of urine in the bladder that cannot be discharged, which is called urinary retention. There are many reasons for urinary retention, which can be divided into two types: obstructive and non-obstructive. Obstructive urinary retention of prostatic hypertrophy, urethral stricture, bladder or urethra stones, tumors and other diseases, obstruction of the bladder neck or urethra and urinary retention.

2 Neurological factors: Central nervous system diseases caused by various causes and autonomic nerve damage caused by diabetes can cause urinary retention.

Diagnosis is based on medical history, symptoms and signs of bladder fullness, and urine can be determined as urinary retention if the urine cannot be discharged or cannot be completely emptied. After the urinary retention was found by visual inspection and percussion of the upper part of the pubis, it was further confirmed by B-ultrasound and catheterization. The cause of the disease depends on the presence or absence of urinary tract infection, urinary tract discharge, urethral injury, prostate lesions, central nervous system infections and diabetes, combined with symptoms, signs and bladder X-ray, B-ultrasound and urethra, cystoscopy, To find out the cause of urinary retention.
Diagnosis
Differential diagnosis
Bladder diverticulum: congenital and secondary, congenital bladder diverticulum wall contains muscle fibers. Acquired multiple secondary to urinary tract obstruction. Patients with bladder diverticulum die before the age of 10 and between 50 and 60 years old. Generally no special symptoms, such as combined with obstruction, infection, dysuria, frequent urination, urgency, dysuria, and some hematuria. In the huge diverticulum, there may be two symptoms of urination, which is a characteristic manifestation of this disease. Combined with imaging examination and endoscopy, the diagnosis can be confirmed.
Huge bladder: huge bladder - huge ureteral syndrome, also known as the huge bladder with a large ureteral sign, characterized by a huge thickening of the bladder-ureter, but no lower urinary tract obstruction and vesicoureteral reflux, no lower urinary tract obstruction. Some people think that a huge bladder or a huge ureter should be diagnosed as a separate disease. With the advancement of inspection techniques, it has been found that the expanded bladder is also reversible, and the ureteral dilatation is also reversible. Regarding the view of no urinary tract obstruction, obstruction is also found. At the same time, the extent to which the ureter and bladder are enlarged can be diagnosed, and there is no standard.
