To investigate the influencing factors for postoperative urinary retention in patients with spinal surgery.

The clinical data of patients with spinal surgery were collected and divided into two groups according to the occurrence of urinary retention (urinary retention group and non occurring urinary retention group). The factors that may affect postoperative urinary retention were compared and multiple factor Logistic regression was used.

Among the 292 patients, 56 cases had postoperative urinary retention and the morbidity was 19.18%. Single factor analysis indicated that Univariate analysis showed that there was a statistically significant difference in anesthetic mode, time of indwelling catheter, time of lying in bed, clamping catheter and timing of removal of urinary catheter (χ²=5.035-22.747, P<0.05 or <0.01). Multivariate Logistic regression analysis showed that the risk factors for urinary retention were time of catheter more than 3 days and bed time is no less than 5 days, and the protective factors were clamping the catheter indwelling training, having a sense of urine and bladder filling.

During the period of indwelling catheter can be closed catheter training, grasp the time of indwelling catheter 1-2 d best catheter time. Urinary catheter should be removed when urine is filled and bladder is filled. At the same time, under the premise of ensuring safety, the patient's bed time should be shortened as far as 5 days, and the rate of urinary retention can be reduced.
