Duplicate bladder

Repeated bladder introduction There are various types of repetitive bladders, complete repetitive bladders, each with a well-developed muscular layer and mucosa, each with a ureter and a complete repetitive urethra, urinating through the respective urethra. Incompletely repeating the bladder, there is only one urethra co-urinating, as well as the sagittal or frontal separation of the bladder, as well as the multi-atrial bladder or gourd-like bladder. basic knowledge The proportion of illness: 0.0006%-0.0008% Susceptible people: no specific population Mode of infection: non-infectious Complications: Bladder valgus Repeat penis Repeat urethra

Repeated bladder cause

Cause:

In the embryonic stage, the urethral urethra primordial division is divided. If the development of the rectum is abnormal, it means that the division occurs before the cloaca is divided into two parts. Otherwise, there is no abnormal development of the rectum, indicating that the division occurs after the cloaca separation, and the embryos are 5 to 7 weeks later. The bladder begins to develop, and if the sagittal or extraneous rectal septum separates the bladder base, it may cause repeated bladder and hindgut repetition.

Some authors believe that the posterior intestine repeat of the embryo is the effect of repeating the bladder. It is also believed that it is caused by excessive growth of the inner and outer germ layers or excessive mucosal folds during the development of the bladder.

Pathogenesis:

1. Completely repeating the bladder The two bladders are completely separated. Each bladder has well-developed muscle layers and mucous membranes, and there are ureters that enter their respective bladders.

2. Incomplete repeating of the sagittal or coronal plane of the bladder, each connected to a ureter, together with a urethra, can be divided into left and right, before and after or two bladders, the middle of the bladder is narrow, forming a gourd-shaped bladder, but not Like a complete repeat of the bladder, there can be traffic drainage into the same urethra, in addition to the odd-shaped multi-atrial bladder.

Repeated bladder prevention

There is no effective preventive measure for this disease. Early detection and early diagnosis are the key to the prevention and treatment of this disease.

Repeated bladder complications Complications, bladder eversion, repeat penis, repeat urethra

1. Repeated bladder can be combined with post-intestinal repetition, and the appendix vertebrae can be combined with other severe urinary tract malformations, such as bladder valgus and ureteral ectopic.

2. 90% of male genital abnormalities are accompanied by repeated penis or repeat urethra, females with repeated fallopian tubes, repeat uterus, repeat vagina.

Repeated bladder symptoms Common symptoms Complex urinary tract infections Urethral mucosa valgus incontinence Urinary calculi

This disease is caused by combination of upper urinary tract or other organ malformation and death or shortly after birth. Clinically, it can be characterized by urinary tract irritation, urinary incontinence and other malformations. However, there are repeated bladders that are asymptomatic for a long time. Or because of complicated urinary tract infection, stones are diagnosed by urography.

Repeated bladder examination

There may be pus cells and red blood cells in the urine when the infection is combined.

1. Imaging examination B-ultrasound and CT examination can be found in the two bladder or bladder with mediastinum, sometimes found multi-atrial bladder or gourd-like bladder, each bladder has a good muscle layer and mucous membrane, can be combined with other organ malformations , intravenous urography, excretory bladder urethra can be clearly diagnosed.

2. Urethral cystoscopy Complete repetitive bladder can be found in the double urethra, double bladder, can only enter one bladder at a time, incomplete repeat bladder can be found in the bladder sagittal or frontal separation, and even multiple atrial bladder.

Repeated bladder diagnosis

B-ultrasound, intravenous urography, excretory bladder urography, urethroscopic cystoscopy and CT examination are effective methods for the diagnosis of this disease.

Bladder diverticulum: more often without other malformations, there is lower urinary tract obstruction, oblique or lateral excretory bladder urethra angiography, found that the diverticulum is located outside the bladder outline, the diverticulum does not shrink when urinating, but expand, B-ultrasound, CT examination of the diverticulum wall Thinner than normal bladder wall.
