Peri-operative bladder management after hip and knee replacement is crucial. Urinary retention affects nearly half of patients, with hypertension and intrathecal narcotics increasing risk. Peri-operative catheterization may reduce complications.

Area of Science:

  • Orthopedic Surgery
  • Urology
  • Anesthesiology

Background:

  • Peri-operative bladder management following major arthroplasty is a debated clinical issue.
  • Urological complications, such as urinary retention and infections, can impact patient recovery after hip and knee replacements.

Purpose of the Study:

  • To evaluate the incidence of urological complications in patients undergoing hip or knee arthroplasty.
  • To identify risk factors associated with developing these complications.

Main Methods:

  • A review of 221 consecutive patients who underwent total hip or knee arthroplasty.
  • Outcomes assessed included prolonged urinary retention, urinary tract infections, and septic prosthesis development.
  • Statistical analysis utilized the two-tailed Fisher exact test to determine the significance of predisposing factors.

Main Results:

  • Urological complications occurred in 47% of patients, with a higher risk observed in hip arthroplasty recipients (p < 0.03).
  • Intrathecal narcotics (p < 0.02) and hypertension (p < 0.05) were associated with increased urinary retention.
  • Peri-operative catheterization reduced urological complications compared to expectant management, without increasing infection rates.

Conclusions:

  • Urinary retention is a common complication after hip and knee arthroplasty, affecting nearly half of patients.
  • Hypertension and intrathecal narcotics are identified as risk factors for urological complications.
  • Peri-operative catheterization appears beneficial in high-risk patients, potentially reducing the need for post-operative catheterizations and infection rates.
