Dialysis

1.6K
Renal failure occurs when the kidneys lose their ability to filter waste products from the blood effectively. It can be classified into two types: acute renal failure (ARF) and chronic renal failure (CRF).
Acute kidney injury develops suddenly and can be caused by pre-renal causes (e.g., hypovolemia, shock), intrinsic renal causes (e.g., acute tubular necrosis), or post-renal causes (e.g., urinary obstruction). In contrast, chronic renal failure progresses gradually over time and is often...

Dialysis

2.0K
Dialysis is a diffusion-based purification process that separates analyte molecules from a complex matrix. This is accomplished by allowing molecules in the solution to pass through a semipermeable membrane into a liquid on the other side. The membrane is usually made of cellulose acetate or cellulose nitrate, and the second liquid must be miscible with the solution. Ions (e.g., chloride or sodium) or organic molecules (e.g., glucose) can pass through the membrane pores, which generally have...

Hemodialysis III: Nursing Management

1.1K
The nursing management of a patient undergoing hemodialysis includes several critical steps, starting with a thorough assessment before the procedure.Before the Hemodialysis ProcedureFirst, record the patient's vital signs—blood pressure, heart rate, respiratory rate, and temperature—to establish a baseline. This baseline is essential for detecting conditions such as hypotension that could impact the patient's response to dialysis. Document the patient's pre-dialysis weight, as this...

DialyzersA hemodialysis (HD) dialyzer is a plastic cartridge containing thousands of parallel hollow fibers, which serve as semipermeable membranes. These fibers are typically made from cellulose-based or other synthetic materials. During HD, blood is pumped into the top of the cartridge and distributed among these fibers. Simultaneously, dialysis fluid, known as dialysate, is introduced into the bottom of the cartridge, bathing the outside of the fibers. Across the semipermeable membrane,...

Chronic Kidney Disease III: Interprofessional Care

503
Chronic kidney disease (CKD) requires collaborative and comprehensive management. CKD progresses through stages and can lead to end-stage kidney disease (ESKD) if untreated. Interprofessional collaboration and patient education are crucial, enabling patients to manage their health and improve their quality of life.Diagnostic approach for chronic kidney diseaseThe diagnosis of CKD primarily focuses on the glomerular filtration rate (GFR), which assesses kidney function by measuring how well...

Hemodialysis I: Introduction

2.1K
Hemodialysis (HD) is a medical treatment that artificially removes waste products, excess fluids, and toxins from the blood when the kidneys are no longer able to perform these functions effectively. In this process, blood is filtered through a semipermeable membrane, allowing for the selective removal of waste while preserving necessary components like blood cells and proteins. Hemodialysis is typically performed in patients with end-stage renal disease (ESRD) or severe kidney...

Summary

Testosterone deficiency is common in men with chronic kidney disease. This study found that hemodialysis (HD) patients had significantly lower testosterone levels than peritoneal dialysis (PD) patients, suggesting dialysis type impacts hormone levels.

Area of Science:

  • Nephrology
  • Endocrinology
  • Men's Health

Background:

  • Testosterone deficiency is prevalent in male patients with chronic kidney disease (CKD).
  • The impact of renal replacement therapy type on testosterone deficiency in CKD is not well understood.

Purpose of the Study:

  • To investigate the association between the type of renal replacement therapy and testosterone deficiency in male patients with CKD.

Main Methods:

  • A cross-sectional study of 79 male dialysis patients (43 hemodialysis, 36 peritoneal dialysis).
  • Measured endogenous testosterone levels, nutritional/inflammatory markers, bone/mineral metabolism markers, anemia, and body composition.
  • Defined testosterone deficiency as levels below 3 ng/ml.

Main Results:

  • Mean testosterone levels were 8.81±6.61 ng/ml.
  • Testosterone deficiency affected 39.5% of hemodialysis patients versus 5.6% of peritoneal dialysis patients.
  • Testosterone levels were independently associated with the hemodialysis technique in multivariate analysis.

Conclusions:

  • Dialysis technique is an independent factor associated with lower circulating testosterone levels in men undergoing dialysis.
  • The dialysis technique may contribute to testosterone deficiency, potentially impacting muscle mass and inflammation.
  • Further research is needed to determine if the dialysis technique directly causes testosterone elimination.
