Here are the indications for dialysis from UptoDate:
* Pericarditis
* Fluid overload or pulmonary edema refractory to diuretics
* Accelerated hypertension poorly responsive to antihypertensive medications
* Progressive uremic encephalopathy or neuropathy, with signs such as confusion, asterixis, myoclonus, wrist or foot drop, or, in severe, cases, seizures
* A clinically significant bleed attributable to uremia
* Persistent nausea and vomiting
* Plasma creatinine concentration above 12 mg/dL (1060 µmol/L) or blood urea nitrogen (BUN) greater than 100 mg/dL (36 mmol/L)
I'm not familiar with your case, so I cannot comment on whether you need dialysis or not. However, if you meet one of these criteria (i.e. discuss them with your physician), then dialysis should be considered.
Followup with your personal physician is essential.
