Do you take any different approaches for patients with end stage kidney disease who are about to be initiated on intermittent hemodialysis and have residual renal function?
The main consideration I have in these patients is making sure I do not try to remove extra fluid; if there is enough residual renal function to provide at least 1,000 ml/day of urine output, most likely this patient will not require net ultrafiltration, only dialysis. By paying attention to this on...
What is your approach to patients with chronic kidney disease who are found to have pelviectasis without hydronephrosis on renal ultrasound imaging?
Good question. I would involve urology early on. I would get more history as to other signs/symptoms of urinary obstruction (nocturia, BPH symptoms, history of retroperitoneal fibrosis). Then, consider a Lasix urogram.
Do you recommend performing surveillance kidney allograft biopsies in your asymptomatic kidney transplant recipients?
In general, I am a believer in management or surveillance biopsies. However, I also think there should be low threshold to forego the biopsy should it put the patient at increased risk, such as anticoagulation or intraperitoneal kidney. The other consideration is what is your plan for treating, or n...
Do you recommend patients consume dairy products over taking calcium carbonate with meals if they have recurrent calcium based nephrolithiasis and persistent hyperoxaluria?
I generally consider the decision between dairy and calcium tablets in the context of other medical conditions. For instance, if the patient has surgical or medical short gut syndrome as a cause of hyperoxaluria, I favor using calcium tablets to help compensate for the enteric loss of bicarbonate in...
What is your preferred intravenous fluid type for matching volume loss in a patient with persistent surgical drain output and pre-renal acute kidney injury?
Probably NS but if the Na crept up at all, would change to 1/2 NS. I dont see a need here for balanced solutions, but wouldn't argue against them.
What is your treatment approach for pregnant patients with IgA nephropathy who have worsening proteinuria during the first trimester?
Difficult question to answer without more details, but I would consider the following factors: One is whether it appears that the IgA is active. When was the last biopsy, and how much hematuria is present? Two would be if this is 'worsening proteinuria' is really just the first time proteinuria has ...
Do you try to treat the acidosis resulting from acetazolamide in patients with IIH?
In general, I do not treat the acidosis of acetazolamide use as it occurs in everyone taking the drug. I only treat it if the symptoms of the acidosis interfere with the patient's activities of daily living.
Do you recommend checking 1,25-hydroxy vitamin D levels in patients with recurrent nephrolithiasis who have hypercalciuria of unknown etiology?
No, unless they are hypercalcemic or I suspect renal sarcoidosis. Stephen B Erickson, MD
How do you monitor multiple myeloma in patients receiving dialysis?
In brief, it depends. I’ve had some patients on dialysis whose light chains completely normalize with treatment and continue to remain normal - and others where the light chains never drop below 100 mg/L even in the setting of MRD negativity. This probably has something to do with the fact that not ...
Under what circumstances do you recommend targeting a systolic blood pressure of less than 120 mmHg in a patient with CKD?
I am going to deviate a bit from the KDIGO recommendations here, and will try to document my reasons. The SPRINT trial, which was the largest BP target trial for individuals with CKD, did not enroll individuals with an eGFR < 20. The automated office BP measurement used in SPRINT is still not standa...
