Postoperative Urinary Retention in Patients Undergoing Orthopedic Procedures: Unilateral versus Bilateral Spinal...

Area of Science:

• Anesthesiology
• Urology
• Surgical Outcomes

Background:

• Postoperative urinary retention (POUR) incidence can be influenced by anesthesia type.
• Limited data exists on POUR rates comparing unilateral and bilateral spinal anesthesia.

Purpose of the Study:

• To evaluate and compare the occurrence of postoperative urinary retention (POUR) after unilateral versus bilateral spinal anesthesia.
• To identify potential differences in POUR development based on spinal anesthesia laterality in orthopedic surgery patients.

Main Methods:

• Comparative study analyzing POUR incidence in two groups: unilateral spinal anesthesia and bilateral spinal anesthesia.
• Statistical analysis included frequency, percentage, mean, standard deviation, Student's t-test, Chi-square test, and Fisher's exact test.
• Significance level set at P < 0.05.

Main Results:

• POUR developed in 2 patients (unilateral spinal anesthesia) and 8 patients (bilateral spinal anesthesia).
• No significant differences were found in mean age, surgery duration, fluid administration, retention symptoms, or need for rescue intervention between groups.
• Time to voiding was a significant factor in symptom presentation for both groups.

Conclusions:

• Unilateral and bilateral spinal anesthesia demonstrate similar rates of postoperative urinary retention in patients undergoing orthopedic procedures.
• Anesthesia laterality does not appear to be a significant predictor of POUR in this surgical context.
