Hemodialysis I: Introduction01:25

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,...

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...
Dialysis01:27

Dialysis

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...
Dialysis01:15

Dialysis

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...
Disorders of the Male Reproductive System01:20

Disorders of the Male Reproductive System

Men's health issues are increasingly recognized as significant, with several conditions posing common threats. Among these, testicular cancer is especially prevalent in younger men, particularly those aged 20 to 35 years. The disease often manifests as a painless mass in the testicles, sometimes accompanied by a sensation of heaviness or a dull ache.
Prostate disorders are another major concern. These conditions can impair urinary flow due to the prostate's location around the urethra. Symptoms...

Area of Science:

  • Nephrology
  • Urology
  • Men's Health

Background:

  • Erectile dysfunction (ED) is a common and distressing issue for patients undergoing hemodialysis.
  • Both organic and psychological factors contribute to the pathophysiology of ED in this population.

Purpose of the Study:

  • To determine the prevalence of sexual dysfunction, specifically erectile dysfunction, among male patients receiving hemodialysis therapy.

Main Methods:

  • A cross-sectional study was conducted with 59 male hemodialysis patients in Iran.
  • The International Index of Erectile Function (IIEF) questionnaire (Persian version) was used to assess sexual function.
  • Data were analyzed using the Chi-square test, with a P-value less than 0.05 considered significant.

Main Results:

  • The mean age of participants was 54.73 years, with a mean dialysis duration of 16.03 months.
  • A high prevalence of erectile dysfunction (86.6%) was observed among the study participants.
  • Both the prevalence and severity of ED significantly increased with advancing age (P < 0.05).

Conclusions:

  • Erectile dysfunction is highly prevalent in male hemodialysis patients.
  • Age is a significant factor associated with increased prevalence and severity of ED in this group.
  • Routine assessment and effective therapeutic interventions for ED should be integrated into the care of hemodialysis patients.
