Background:
To evaluate the clinical significance of low-frequency electrical stimulation in preventing urinary retention after radical hysterectomy.
Methods:
A total of 91 women with stage IA2-IB2 cervical cancer, who were treated with radical hysterectomy and lymphadenectomy from January 2009 to December 2012, were enrolled into this study and were randomly divided into two groups: trail group (48 cases) and control group (43 cases). Traditional bladder function training and low-frequency electrical stimulation were conducted in the trail group, while patients in the control group were only treated by traditional bladder training. The general condition, rate of urinary retention, and muscle strength grades of pelvic floor muscle in the perioperative period were compared between these two groups.
Results:
The incidence of postoperative urinary retention in the electrical stimulation group was 10.41%, significantly lower than that in the control group (44.18%), and the difference was statistically significant (P < 0.01). The duration of postoperative fever and use of antibiotics were almost the same between these two groups. Eleven days after surgery, the difference in grades of the pelvic floor muscle between these two groups was not statistically significant. However, 14 days after the operation, grades of the pelvic floor muscle were significantly higher in the trail group than in the control group, and the difference was statistically significant (P < 0.01). In addition, although there was no significant difference between the two groups with different parameters (P = 0.782), the incidence of urinary retention was lower in the endorphins analgesia program group than in the neuromuscular repair program group (9.09% < 11.54%).
Conclusion:
Low-frequency electrical stimulation is more effective than conventional intervention in preventing urinary retention after radical hysterectomy. It also intensifies the recovery of pelvic muscle strength.

The kidneys are bean-shaped organs located in the retroperitoneal space, on either side of the vertebral column, between the T12 and L3 vertebrae. They are partially protected by the rib cage and surrounded by perirenal fat, which provides cushioning. They are responsible for urine formation and play critical roles in regulating blood pressure, electrolyte levels, and hormone production. The ureters...
