Renal heterotopia with ureteral heterotopia

Introduction Renal ectopic refers to the normal position of the well-developed kidney that does not reach the retroperitoneal pelvic fossa. The ureteral ectopic opening refers to the ureteral opening outside the normal position. The ectopic ureteral opening is characterized by normal intermittent urination with persistent leakage of urine and repeated urinary tract infections. Men are more likely to open in the posterior urethra, ejaculatory ducts, seminal vesicles, etc., while women can open in the anterior urethra, vagina, vestibule and cervix. About 80% of the ureteral ectopic is seen in the upper ureter in the double ureter. More than 80% of bilateral ureter and ureteral ectopic findings are seen in women, and a single ureteral ectopic is more common in men. About 10% of the ureteral ectopic is bilateral.

Cause

The ectopic ureteral opening is characterized by normal intermittent urination with persistent leakage of urine and repeated urinary tract infections. Under normal circumstances, the two kidneys have reached the second lumbar level at the 8th week of the fetus. The occurrence of ectopic kidney is caused by factors such as ureteral bud growth disorder, abnormal blood supply or excessive growth of Wolff tube during the 4th to 8th week of fetal growth, causing the kidney to rise, overspeed or falsely rise to the opposite side. This leads to kidney ectopic or poor rotation.

Most of the renal ectopic clinical symptoms have no typical symptoms, mainly due to obstructive stones on the affected side. Ectopic kidneys are rarely found to be caused by squeezing of adjacent organs, but also by urinary tract infections or palpable abdominal masses. Occasionally, urinary incontinence due to renal ectopic ureteral ectopic reporting of colonic displacement usually provides a basis for the diagnosis of pelvic or lumbar ectopic kidney.

Differential diagnosis

Need to be identified with the following symptoms:

Bladder vaginal fistula: vaginal vagina, a type of urinary fistula. Urinary fistula refers to the abnormal passage formed between the reproductive organs and the urinary system, which is characterized by leakage of urine. The genital fistula is an extremely painful injury. Because the urine can not be controlled by itself, the genital area is soaked in the urine for a long time, which not only brings physical pain to the woman, but also the patient can not participate in the production labor because of fear of being close to the masses, and the mental burden is also great. Bladder vaginal fistula, the pupil is located in the mouth of the urethra and / or above, such as the pupil is larger, the urine is completely leaked from the vagina, and the patient can not urinate at all. If the pupil is small and the granulation is formed around the pupil, the patient can often control a part of the urine, and when the bladder is overfilled, there is an overflow of urine.

Urinary fistula: Urinary fistula refers to the abnormal passage formed between the reproductive organs and the urinary system, which is characterized by leakage of urine. Common vaginal fistula, urethra vagina, ureterovaginal fistula (collectively called urinary fistula). The genital fistula is an extremely painful injury. Because the urine can not be controlled by itself, the genital area is soaked in the urine for a long time, which not only brings physical pain to the woman, but also the patient can not participate in the production labor because of fear of being close to the masses, and the mental burden is also great. Strengthening the health care of pregnant women, carrying out new births, correctly handling childbirth, improving the quality of surgery, and genital damage can be avoided. The occurrence of genital fistulas will inevitably be greatly reduced.
