CATHETERIZATION: A COMPREHENSIVE GUIDE
  1. INTRODUCTION

Definition

Urinary catheterization is a medical procedure involving the insertion of a hollow, flexible tube (catheter) into the urinary bladder through the urethra for the purpose of draining urine, measuring output, or instilling medications (Potter & Perry, 2021).

Historical Background

  • Ancient times: Hollow reeds and metal tubes were used
  • 1853: Jean François Reybard introduced rubber catheters
  • 1930s: Frederic Foley developed the self-retaining balloon catheter
  • Modern era: Silicone and hydrogel-coated catheters developed

Anatomy Review

Understanding the urinary system anatomy is essential:

  • Female urethra: 3-4 cm long
  • Male urethra: 18-20 cm long
  • Bladder capacity: 300-500 ml in adults
  1. TYPES OF CATHETERIZATION
  2. Based on Duration
  3. Intermittent (In-and-Out) Catheterization
  • Single-use catheter inserted to empty bladder
  • Removed immediately after drainage
  • Duration: Few minutes only
  1. Indwelling (Retention) Catheterization
  • Remains in place for extended periods
  • Secured by inflation balloon
  • Duration: Days to weeks
  1. Suprapubic Catheterization
  • Inserted through abdominal wall
  • Directly into bladder
  • Surgical procedure required
  1. Based on Catheter Material
Material Duration Characteristics
Latex Short-term (up to 14 days) Flexible, inexpensive, allergy risk
Silicone Long-term (up to 12 weeks) Hypoallergenic, rigid
Teflon-coated Medium-term (up to 28 days) Reduced friction
Hydrogel-coated Long-term Biocompatible, comfortable
Silver-alloy coated Long-term Antimicrobial properties
PVC Short-term/Intermittent Disposable, economical
