Abstract
Background: Perineal diseases are common worldwide, and surgical treatment often requires spinal anesthesia. Urinary retention is a frequent complication after spinal anesthesia, and management options include warm compresses, medications, and urinary catheterization. Objectives: To evaluate the effectiveness of warm compress therapy in managing urinary retention after perineal surgery under spinal anesthesia. Methods: Ninety-eight patients undergoing perineal surgery with spinal anesthesia who developed urinary retention were treated with warm compresses applied to the suprapubic region for 2–3 hours. If patients experienced unbearable pain or urgency during the warming period, alternative interventions such as neostigmine injection or urinary catheterization were performed. Results: The incidence of postoperative urinary retention was high at 48.9%. The factors associated with postoperative urinary retention include: male gender, surgery duration longer than 50 minutes, intraoperative fluid infusion greater than 700 ml, and concomitant use of intrathecal morphine. Warm compress therapy achieved a relatively high success rate of 60.4% in resolving urinary retention. Among successful cases, the mean time to first urination was 5.5 hours, ranging from 0.33 to 3.33 hours. The mean time to return to normal voiding was 3.33 hours, with a minimum of 0.33 hours and a maximum of 13 hours. Conclusion: Warm compress therapy is an effective and minimally invasive method for the treatment of postoperative urinary retention in patients undergoing perineal surgery under spinal anesthesia.
