Insights

Prostate-specific antigen (PSA) levels are lower in men undergoing hemodialysis (HD) compared to non-uremic individuals. This study clarifies PSA diagnostic validity in HD patients.

Area of Science:

  • Urology
  • Nephrology
  • Oncology

Background:

  • The diagnostic utility of prostate-specific antigen (PSA) in men undergoing hemodialysis (HD) is not well-established.
  • PSA is a key biomarker for prostate cancer screening and management.

Purpose of the Study:

  • To evaluate PSA levels in men receiving HD.
  • To compare PSA levels in HD men with those of non-uremic controls.

Main Methods:

  • PSA levels were measured in 620 HD men and compared to 3,636 non-uremic controls.
  • Prostate biopsies were performed for HD men with PSA >4.1 ng/ml.
  • Cancer-free status was defined by PSA levels and biopsy results.

Main Results:

  • Cancer-free HD men exhibited significantly lower mean PSA levels across age groups compared to controls.
  • Mean PSA in cancer-free HD men ranged from 1.0 to 2.1 ng/ml by age decade.
  • Biopsies in HD men with elevated PSA revealed a lower cancer detection rate than anticipated.

Conclusions:

  • Men undergoing hemodialysis demonstrate lower PSA levels than their non-uremic counterparts.
  • These findings suggest potential adjustments in PSA interpretation for HD patients.

Hemodialysis III: Nursing Management

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 measurement...

Hemodialysis I: Introduction

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...

Hemodialysis II: Procedure and Complications

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

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...

Extracorporeal Removal of Drugs: Peritoneal Dialysis and Hemodialysis

Patients with end-stage renal disease (ESRD) or those experiencing drug overdose often require extracorporeal methods to eliminate accumulated drugs and metabolites. Hemoperfusion, hemofiltration, and dialysis are the primary techniques to rapidly remove harmful substances without disrupting the patient's fluid and electrolyte balance. For those with compromised renal function, dosage adjustments of concurrent medications may be necessary during extracorporeal drug removal.Dialysis is a process...

Accurate diagnosis and effective prevention are critical in managing Acute Kidney Injury (AKI), which is linked to high mortality rates ranging from 10% to 80%. Timely recognition of at-risk patients and careful monitoring can significantly reduce the likelihood of kidney damage.Diagnostic Assessments:The diagnostic process starts with a comprehensive medical history to identify prerenal, intrarenal, and postrenal causes.Prerenal causes, such as dehydration, hypotension, or blood loss, should...
