Are there any special considerations when treating patients with recurrent nephrolithiasis who also have medullary sponge kidney?
Sponge kidney patients present a very challenging therapeutic situation. Anatomically speaking, a sponge kidney is often a congenital, although occasionally acquired, dilation of the renal collecting ducts, which in turn causes the inability to acidify urine. Urine pH is typically unusually alkaline...
What is your approach to initiating spironolactone in patients with end stage kidney disease and heart failure?
Not sure that we have a consensus answer for this question, but spironolactone in hemodialysis patients likely causes more harm than good.There are data suggesting that spironolactone increases the risk for arrhythmia (heart block or bradycardia; Mc Causland et al., PMID 36763641) and hyperkalemia (...
How has the FLUID trial, which showed no significant difference in death or readmission rates between Lactated Ringer’s solution and normal saline, influenced your approach to IV fluid management?
The choice between normal saline and Lactated Ringer's should be individualized. Normal saline is preferred in patients with hyponatremia or metabolic alkalosis. Lactated Ringer's is preferred in patients with hyperchloremic acidosis, and it should be avoided in patients with hyponatremia since its ...
How do you decide when to implement a "renal diet" (i.e., restricting electrolyte and/or fluid intake) in hospitalized patients with renal impairment?
I think about this from several perspectives: First, what's the severity of the renal impairment? Generally, I consider electrolyte abnormalities like hyperkalemia and hyperphosphatemia more likely to occur when the eGFR is <60 (for hyperphosphatemia, it might be more evident when the eGFR drops bel...
Do you recommend patients with hypertensive kidney disease transition from wrist to upper-arm home blood pressure monitoring prior to making dose adjustments to their antihypertensive regimen?
Possibly, if I think the measurements are not accurate. Home BP monitoring is an important part of hypertension management. In my practice, I've noticed that positioning while taking the BP is more important than the specific device type. I advise patients to check their BP at home in a hard-backed ...
Do you plan to incorporate fish-oil supplementation into the care of hemodialysis patients to reduce cardiovascular events in light of the PISCES trial results?
I showed the paper to an Internal Medicine friend of mine who is more statistically savvy than me. He wrote this: "So I read the study, and I’m still at a loss to understand it. I’m pretty Bayesian, but this study breaks my priors. Prior studies were basically negative, not to mention that nothing e...
What is your approach for arranging outpatient antibiotics on discharge for a hospitalized patient with ESKD who receives in-center hemodialysis at a unit you do not round at?
In the US, antibiotic orders administered in a dialysis facility must come from a clinician who is credentialed at that unit, typically the outpatient nephrologist or the medical director, if the outpatient nephrologist is unavailable. One cannot place orders directly to a unit where he/she has no p...
Do you recommend avoiding morphine in patients with ESKD?
I would not recommend using other than for a few doses for acute severe pain but not for more prolonged use other than in the setting of terminal illness/hospice.
How do you approach recommending an AVF for a patient with advanced CKD who is concerned about the cosmetic appearance of the fistula?
My approach is usually 2-fold. First, I try to emphasize the medical benefits of an AVF over a catheter. Second, I point out that the catheter is also the most aesthetically appealing option to have. I then go over possible solutions of covering the AVF (sleeves, etc.). This could also be a good ...
Do you prefer maximizing fluid removal during dialysis or starting new antihypertensive medications for patients with ESKD on intermittent hemodialysis who are chronically hypertensive?
Fluids, fluids, and fluids are the most crucial first step. Challenging dry weight is the most important part in controlling blood pressure, and then adding more blood pressure medications is the next step. The only "exception" is high dose diuretics to reduce intradialytic weight gain. Additionall...
