[Urodynamic effects of elongated needle on patients with urinary retention after spinal cord injury].

Objective: To explore the clinical significance of elongated needle in the treatment of urinary retention after spinal cord injury.

Methods: From January 2016 to June 2018, 60 patients with urinary retention after spinal cord injury were divided into elongated needle acupuncture group and needle acupuncture group, 30 cases in each group. The Shuidao(ST28) and Zhibian(BL54) were selected as the treatment of acupoints. In the elongated needle group, there were 23 males and 7 females, with a mean age of(52±9) years old. The patients in this group were treated on both sides, and the electro-acupuncture apparatus was used for 30 minutes at frequencies of 3 Hz for 30 minutes. In needle group, there were 24 males and 6 females, with a mean age of (56±10) years old. After treatment, the needles were retained for 30 minutes. The treatment frequencies of both groups were once every other day and passed for 2 months. After 2 months of treatment, the clinical significances of the treatment of the disease were explored by analyzing the time between the two groups of patients to reach the equilibrium bladder, diary urinary diary, urodynamics and urinary tract infection between the two groups.

Results: (1)Time to reach the equilibrium bladder:(39.5±1.2) days in elongated needle group and (46.5±2.1) days in needle group; the time to reach the equilibrium bladder in the two groups was significantly different(<0.05). (2)Comparison of urination diary between the two groups:the daily number of catheterization, the amount of each catheterization, the number of daily urination, and the amount of urine per urination after treatment were better than those before treatment by intra-group comparison(<0.05); the number of daily catheterization, the amount of daily catheterization, the number of daily urination, and the amount of urine output per patient in elongated needle group were better than those in needle group by comparison between two groups(<0.05). (3)Comparison of improvement of urinary tract infection between the two groups:the urinary tract infection were better than that before treatmant in each group by intra-group comparison; the improvement rate of urinary tract infection in awn needle group (1/3.3%) was higher than that in needle group(5/16.7%), with significantly differences. (4)Comparison of urodynamic index between two groups:by intra-group comparison, the VH2O, Pves, Pdet, Qave, Qmax, and BC of the two groups were better than those before treatment(<0.05); By comparison between two groups, the improvement of VH2O, Pves, Pdet, Qave, Qmax and BC were better than those of the needle group (all <0.05).

Conclusions: The elongated needle is better than conventional needle in improving urinary retention, urinary tract infection and urodynamic index in patients with urinary retention after spinal cord injury. It has positive significance in improving patients' quality of life and is worth applying to clinical.
