Renal ectopic opening is the failure of a well-developed kidney to reach its normal location within the retroperitoneal fossa. Ureteral ectopic opening is defined as the opening of the ureter in a location other than its normal position. Renal ectopia should be distinguished from renal prolapse, in which the kidney is initially in a normal position and has a normal blood supply, but for some reason moves downward, whereas an ectopic kidney is not in a normal position from the beginning. Ectopic kidneys are commonly found in the pelvis, iliac fossa, abdomen, thorax, or crossed ectopic kidneys. Ureteral ectopic openings are mainly characterized by normal intermittent urination with persistent leakage and recurrent urinary tract infections. In men, the ectopic openings are usually in the posterior urethra, ejaculatory duct, and seminal vesicles, while in women, they can be in the anterior urethra, vagina, vestibule, and cervix. About 80% of ureteral orifices are ectopic in the upper ureter in both ureters. More than 80% of bilateral ureters with ureteral orifice ectopia are seen in females, while single ureteral orifice ectopia is more common in males. About 10% of ureteral orifice ectopia is bilateral. So, what tests are needed for patients with renal ectopic with ureteral ectopic? The following is a brief introduction: 1. urinalysis: you can see whether there is urine sugar, urine protein, red blood cells, white blood cells, crystalline matter, bacteria, etc. 2.Blood test: If high white blood cell count is found in blood routine, it means there may be infection. 3.X-ray examination: X-ray examination is one of the most important methods to diagnose urinary tract, but it is not suitable for pregnant women. 4.B ultrasound: It can diagnose the presence or absence of other combined lesions in the kidney and determine whether there is fluid in the kidney. 5.CT examination.
