The Effect of Magnetic Therapy on Postoperative Urinary Retention in Patients Undergoing Surgery: A Randomized...

Urinary retention is a postoperative problem that causes pain and discomfort for patients, even when catheters are used. The potential role of magnetic therapy in treating postoperative urinary retention through acupuncture points remains uncertain. This research aims to assess the impact of magnetic therapy on urinary retention in patients undergoing surgery.

This single-blind clinical trial study was conducted in a recovery department within an operating room and subsequently in the Surgery Department of Amin Hospital. The study took place in Isfahan in 2022, with a sample of 64 patients selected using a simple random sampling method and divided equally into two groups. In the intervention group, magnet plates were applied, while the control group received iron plates at seven specific points for duration of 35 ± 5 minutes. Demographic information, the type of urinary excretion, the duration of urinary retention, and the volume of excreted urine were recorded using a researcher-made checklist for both intervention and control groups. These data were compared and subjected to descriptive and analytical statistical analysis.

Among the participants (N = 64), the majority were male (N = 37, 57.80%), and the mean age was 40.17 years. The Chi-square analysis revealed no significant difference between the intervention and control groups in terms of the type of urinary excretion (p = 0.106). However, the Mann-Whitney U-test demonstrated significant difference between the two groups regarding the duration required to eliminate urinary retention and the volume of excreted urine (F_2,41 = 62 and F_1,76 = 62; p < 0.001).

The use of a novel approach involving magnetic therapy applied to acupuncture and reflexology points has been shown to reduce the time required for the first urination and increase the volume of urine in post-surgery patients.
