Ep 4 · 9:01
quote
we really like urine and we're talking about babies who have urine, if we're talking about measuring things in the urine prenatally or shunting things.

Ep 4 · 9:26
clinical
Any kind of urine output, even poor-quality urine that is mostly water without cleared metabolites, is much better than no urine for both prenatal and postnatal management.

Ep 4 · 9:46
clinical
Infants with obstructive uropathy often have a concentrating defect and produce large volumes of urine, which may be poor quality but is still beneficial as fluid.
↗

quote
It may again be bad urine, but at least it's fluid.

clinical
At this center, infants are typically transplantable at a size between 8 and 10 kg, which usually occurs in the second year of life.
↗

clinical
Lower urinary tract management in infants with obstructive uropathy requires collaboration with pediatric urologists and includes antibiotic prophylaxis, bladder irrigations, and bladder pressure management with anticholinergics and catheterization programs.
↗
▶
Ep 4 · 13:40
clinical
Obstructive uropathy bladders can have very high pressure and can change over time, requiring regular urodynamic studies and potentially changing management strategies.
↗
▶
Ep 4 · 14:33
clinical
Infants with chronic kidney disease from obstructive uropathy typically do not have significant hypertension because they have high urine output and are not volume overloaded, and they lose sodium due to tubular dysfunction.
↗
▶
Ep 4 · 15:13
clinical
Chronic kidney disease management in infants requires supplementation of erythropoietin and iron to prevent anemia, which has negative cognitive, energy, and quality-of-life effects.
↗
▶
Ep 4 · 15:47
clinical
Untreated secondary hyperparathyroidism from advanced CKD impairs bone and skeletal health, which is especially problematic in growing children.
↗
▶
Ep 4 · 16:03
clinical
Advanced chronic kidney disease not requiring dialysis often causes metabolic acidosis, which is harmful to growth and well-being and requires buffering with citrate supplementation.
↗
▶
Ep 4 · 16:20
clinical
Specialized nutrition management in infant CKD includes formula modification and pre-treatment with potassium-binding resins to prevent hyperkalemia.
↗
▶
Ep 4 · 16:44
clinical
Infants with advanced CKD have feeding and swallowing difficulties and require occupational therapy, physical therapy, and feeding team involvement for developmental support.
↗
▶
Ep 4 · 18:25
clinical
Standard chronic kidney disease staging based on GFR does not apply to children under 2 years of age because normal infants spend their first year developing normal kidney function, with GFR rising from about 50 at one month to about 100 by one year.
↗
▶
Ep 4 · 21:39
clinical
The decision to initiate dialysis is based on failed chronic kidney disease management—inability to support growth (including head circumference) or medically manage hyperkalemia or metabolic acidosis—not on creatinine level alone.
↗
▶
Ep 4 · 22:22
clinical
Peritoneal dialysis is the modality of choice for infant dialysis because it is the technically least difficult approach in small children.
↗
▶
Ep 4 · 23:04
clinical
Peritoneal dialysis introduces a major additional layer of complexity and quality-of-life burden for parents, who are typically taught to perform dialysis at home.
↗
▶
Ep 4 · 23:26
opinion
When counseling parents about infant dialysis, the focus should be on the length of time it may be needed (until the child reaches transplantable size at 8-10 kg, typically in the second year of life) and the complexity of the therapy package.

Ep 4 · 23:47
quote
typically our parents will tell us that if they both held jobs prior to having to take care of a complicated, complicated, challenging baby like this, uh, when that started, one of them usually stopped working and, and the baby became his or her job.
↗
▶
Ep 4 · 23:47
clinical
Parents typically report that when their baby requires complex care including dialysis, one parent usually stops working and caring for the baby becomes their full-time job.
↗
▶
Ep 4 · 24:11
clinical
Residual urine output is a major advantage in managing fluid balance during dialysis; it is very difficult to manage fluid balance with dialysis alone without some residual diuresis.
↗
▶
Ep 4 · 24:26
opinion
It is difficult to justify placing a patient on chronic dialysis without some prospect of transplantation, as this creates a never-ending one-way street that becomes very challenging.
↗
▶
Ep 4 · 28:58
clinical
When peritoneal dialysis is not available due to peritonitis, short-term hemodialytic strategies can be attempted but are challenging because they require blood priming of circuits and very large catheters in small blood vessels.
↗
▶
Ep 4 · 29:16
clinical
Aquaphoresis (ultrafiltration with convective clearance) using slightly smaller catheters than hemodialysis has been successfully used to maintain anuric babies with intraperitoneal problems or those requiring major abdominal surgeries.
↗
▶
Ep 4 · 31:28
clinical
Nutrition management is easier in infants with urine output compared to oliguric or anuric infants because formula does not need to be as concentrated.
↗
▶
Ep 4 · 31:43
clinical
High-output infants with CKD lose electrolytes including potassium and phosphorus, requiring supplementation of electrolytes that are typically restricted in older CKD patients.
↗
▶
Ep 4 · 32:06
clinical
Formula density for infants with CKD is inversely related to urine output volume.
↗
▶
Ep 4 · 32:18
clinical
Dietitians calculate required calories for growth and required protein intake while ensuring BUN does not reach dangerously high levels; the inability to provide adequate protein without excessive BUN may necessitate dialysis.
↗
▶
Ep 4 · 32:45
clinical
It is relatively unusual to expect infants with advanced CKD to drink spontaneously in amounts sufficient to supply required nutrition.
↗
▶
Ep 4 · 33:03
clinical
Breast milk from motivated mothers can be incorporated into specialized formulas that meet the infant's specific nutritional needs; this is typically pumped breast milk.
↗
▶
Ep 4 · 33:39
clinical
The majority of infants with advanced CKD have either an NG tube or gastrostomy tube for feeding, which is maintained even around transplant time for medication administration.
