Whether kidney function can be restored after abdominal dialysis is divided into two cases: 1, acute renal failure or chronic renal failure after the acute exacerbation period, lifting the factors of kidney damage, kidney function may be restored. 2, chronic renal failure, that is, chronic kidney disease gradually progress chronic renal failure, into the uremic phase, the kidneys have shrunk or become smaller, or even very thin, can not be restored. As some of the acute renal failure is prerenal, the patient sweats a lot, nausea, vomiting, not eating, appearing prerenal, blood volume deficiency renal failure. Through clinical rehydration and correction of blood volume deficiency performance, renal function will gradually recover, or some of the post-renal renal failure, renal function pipeline system such as ureter, urethra obstruction. In patients with common clinical tumors, such as ovarian tumors with intra-abdominal tumor compression of ureter, post-renal renal failure occurs, and renal function can be recovered if the obstruction is lifted in a short time before irreversible damage to renal function occurs. If the starting disease of chronic renal failure is chronic kidney disease, gradually to the stage of chronic renal failure into uremia, the kidney has atrophied and has no function at all, through abdominal dialysis can only improve the symptoms, such as eliminating edema, excreting toxins, nausea, vomiting better, can adjust electrolytes, etc. Therefore, whether kidney function can be restored after abdominal dialysis depends on the specific situation of the patient and cannot be generalized.
