Comprehensive Guide to Catheterizations in Urology: Techniques, Indications, and Risks

This comprehensive guide covers various aspects of catheterization in urology, including indications, techniques, catheter types, balloon inflation, complications, and preventive measures. Learn about different catheter sizes, uses of large-caliber catheters, balloon inflation risks, latex allergies, prevention of catheter-associated UTIs, and procedures like ureteric stenting and suprapubic catheterization.

Presentation Transcript

  1. INSTRUMENTS Dr. Abdellatif Zayed Amzayed_1919@yahoo.com

  2. Indications of catheterizations • Diagnostic: • Cystourethrography • Urodynamic study • Measure Residual urine • Therapeutics: • Relief of urine retention (BPH,…) • Clot retention • Postoperative

  3. French scale • Catheter sizes refer to the outside circumference • French (Fr) scale (circumference is in mm) • 1 Fr=0.33 mm in diameter.

  4. Strait catheter

  5. Fixations of strait catheter by plaster strips

  6. Foley’s catheters

  7. Self retaining catheter

  8. Catheter (18-16F) is usually satisfactory for adults. • Inflating the balloon prematurely may result in urethral rupture

  9. Large-caliber catheters are used to evacuate blood clots • Why Large balloons (30 mL)?? • To decrease the balloon migrating into the prostatic fossa after TUR_P. • Can be used as traction to control hemorrhage from the prostatic fossa

  10. The standard latex catheter can result in severe reactions in patients with latex allergies • Silicone varieties are good alternatives even if it is to remain only for few days

  11. Catheterizations

  12. Catheter associated UTI Incidence: • short term catheterization 10-20% • Long term catheterizations 100% Guideline to prevent catheter associated UTI • Only when necessary • Condom catheter • Aseptic catheterization technique • Using sterile lubricant

  13. Condom catheter Elastic adhesive band

  14. The bag below the bladder levelShould not touch the floorIn males, the catheter should be secured above the thigh Guideline to prevent catheter associated UTI

  15. The balloon may not deflate!!!!!!!

  16. Deflating by using torsion

  17. Shortening the defective length

  18. Transluminal probing and perforation Probe

  19. Percutaneous puncture U/S guided puncture

  20. Transrectal or transvaginal puncture Transrectal Transvaginal

  21. Harpoon technique

  22. Rupture by overdistention

  23. Chemically induced rupture Obsolete !!!

  24. Ureteric stents

  25. Bilateral JJ stents, Stienstrass

  26. Ureteric stents

  27. Double-J catheters • Facilitate internal drainage due to obstruction from internal or external ureteral compression • To decrease sepsis or obstruction in the presence of steinstrasse after ESWL

  28. Ureteral catheterization • performing retrograde pyelography • collecting urine for cytology or cultures • performing brush biopsies • Draining an obstructed kidney

  29. Suprapubic catheter

  30. Suprapubic Catheter insertion

  31. Cystoscope

  32. Flexible ureteroscope

  33. Nephroscope
