What Is a Pelvic Kidney?

Renal ectopic means that a well-developed kidney cannot reach the normal position in the retroperitoneal renal fossa. Renal ectopic should be distinguished from renal sagging, which means that the kidney is initially in a normal position and has a normal blood supply, but for some reason the downward movement occurs, and the ectopic kidney is not in the normal position from the beginning. Ectopic kidneys are common in the pelvis, popliteal fossa, abdomen, chest, or cross-renal ectopic. Clinically, there are more female patients. The main reason is that female patients have a higher urinary tract infection rate than men, which makes it easier to find abnormalities in imaging examinations. The left side generally has a higher incidence than the right side.

Simple Ectopic Renal Etiology

Under normal circumstances, the two kidneys of the fetus at the 8th weekend have reached the level of the second lumbar spine. The development of ectopic kidneys is caused by the failure of ureteric bud growth, abnormal blood supply, or excessive growth during the rise of the kidneys in the 4th to 8th weeks of the fetus. Ectopic or poor rotation.

Clinical manifestations of simple renal ectopic

The disease has no typical symptoms in the clinic, mainly due to obstructive stones on the affected side. Ectopic kidneys are rarely caused by the compression of adjacent organs, but they are also found due to urinary tract infections or accessible abdominal masses.

Renal ectopic examination

With the application of radiography, ultrasound, radionuclide scanning and other urinary tract imaging techniques, the diagnosis of asymptomatic ectopic kidneys has gradually improved. Secretory urography or renal ultrasound can easily confirm the diagnosis. In addition, radionuclide scanning, retrograde angiography, and CT often provide useful information for diagnosis. A cystoscopy alone is not sufficient to diagnose renal ectopic, unless abnormalities in the ureteral orifice also indicate a lesion in the upper urinary tract. Angiography is helpful in understanding renal blood flow and determining the surgical plan, especially for unilateral heterotopic kidneys.

Simple renal ectopic diagnosis

The disease has no typical symptoms in the clinic, mainly due to obstructive stones on the affected side. It has also been found due to urinary tract infections or palpable abdominal masses. Occasionally, urinary incontinence has been reported due to renal ectopic ureteral ectopic, and the displacement of the colon can usually provide a basis for the diagnosis of pelvic or lumbar ectopic kidneys.

Renal ectopic therapy

Asymptomatic patients do not need to be treated, and those with comorbidities should be treated symptomatically. In severe complications such as severe hydrops or pus, nephrectomy is usually feasible for the contralateral kidney.
