Hydronephrosis not necessarily cut kidney

Hydronephrosis is not an independent disease, but due to urinary obstruction caused by renal pathology. The main function of the kidney is to make the body produce urine metabolic waste excreted by the urinary tract. Regulation of body acid-base balance and secretion of erythropoietin so. From the kidney collecting duct has been outside the mouth of the urethra, the obstructive position will affect the discharge of urine caused hydronephrosis. Urinary obstruction for many reasons : to congenital malformations in children more commonly, the most common is UPJ congenital abnormalities, regardless of whether there may narrow because the area ureteral wiggle bad, not entirely through urine caused hydronephrosis. Adult common causes of urinary calculi, inflammatory narrow, tumor and external oppression. Retroperitoneal fibrosis neurogenic bladder and urethra and other diseases may cause bilateral hydronephrosis, older men prostatic hyperplasia can also cause bilateral hydronephrosis. Apart from congenital hydronephrosis, other causes of hydronephrosis regular inspection by the original disease was detected. While congenital hydronephrosis are unwittingly the long process of gradually increasing with, and often without obvious clinical symptoms. In children with abdominal part of the Bulge or apparent mass, or is the intermittent abdominal pain, the only treatment was found. Thus, hydronephrosis can be found at any age. The first fetus 7-8 months may be found by ultrasound. Found hydronephrosis, should be further intravenous and retrograde pyelography to understand kidney function and the site of obstruction. Right IVP not autoradiography, radionuclide scanning can add valuation impaired renal function. CT scan can show that the renal size, contour, and renal function and the thickness of certain retrograde pyelography the site of obstruction. Of course, not every patient has to do all the checks. Correct valuation water kidney especially great hydronephrosis renal function, the treatment of renal water is of great significance. When adults hydronephrosis volume over 1000 ml, children hydronephrosis more than 24-hour urine volume, the total number of have been designated for giant hydronephrosis. Past that, as long as the contralateral kidney is good, the huge water kidney can be removed. Our long-term clinical practice proved that giant hydronephrosis considerable part (approximately 70%) of the cases of obstruction by lifting or Nephrostomy drainage, kidney function can be given a greater degree of restoration. Not simply hydronephrosis of the number of kidneys to measure whether there is a function, intrarenal hydronephrosis due pelvis alone can not expand outwards, despite water volume is not great, but the emergence of early renal parenchymal pressure thinner, serious impairment of renal function and renal pelvis appearance hydronephrosis can expand outwards, stagnant water may even be more and renal pressure thinning may not very serious. IVP not autoradiography not fully account for no kidney function, because intravenous pyelography of kidney profiling by many factors. Therefore, in the treatment of giant hydronephrosis when water is removed or retained renal kidney, should have a conceptual change, there should be quantifiable indicators. 1. Through B - CT scan found renal parenchyma in the thickness of 3 mm and above surgery see renal parenchyma thickness 3 mm above the region accounted for 50% over the lifting of obstruction, or pyeloplasty Nephrostomy, kidney can restore some functions and should be retained. 2. Surgery stagnant water collected in the urine pH, 7.1 to 7.30 following kidney can be retained. 3. Surgery can be sent from renal cortex frozen biopsy, normal or close to normal glomerular accounted for more than half, kidneys can be retained.
