Abstract:Objective To evaluate the efficacy of pyridostigmine bromide combined with tamsulosin in the prevention and treatment of bladder dysfunction after radical hysterectomy and its impact on urodynamics.Methods A total of 120 cervical cancer patients undergoing radical hysterectomy in Gansu Tumor Hospital from August 2019 to March 2022 were divided into three groups according to the random number table method. Forty cases in group A were treated with pyridostigmine bromide 5d after operation. 40 cases in group B were treated with simple urethral catheterization; and 40 cases in the group C were treated with pyridostigmine bromide combined with tamsulosin 5d after operation. The residual urine volume, lower urinary tract/bladder dysfunction scale (MHU) score, and urodynamic index changes at different time points after surgery were observed in the three groups, and the complications, total time of indwelling urinary catheter, postoperative bladder function recovery, and adverse effects were compared among the three groups.Results The residual urine volume, MHU score, bladder maximum capacity, bladder initially sensed capacity, and detrusor compliance in three groups at different time points were compared using the repeated measures design analysis of variance. The results showed that (1) There were significant differences in residual urine volume, MHU score, bladder maximum capacity, bladder initially sensed capacity, and detrusor compliance at different time points (P < 0.05). (2) The differences of residual urine volume, MHU score, maximum bladder capacity, initially sensed bladder capacity, and detrusor compliance among the three groups were statistically significant (P < 0.05); the residual urine volume and MHU score in group C at two weeks, three weeks, two months, and three months after surgery were lower than those in group A and group B; the maximum bladder capacity, initially sensed bladder capacity, and detrusor compliance were higher than those in group A and group B. (3) The trend differences of residual urine volume, MHU score, bladder maximum capacity, bladder initial sensation capacity, and detrusor compliance were statistically significant (P < 0.05); the incidence of postoperative lower urinary tract/bladder infection and total duration of indwelling urinary catheter in group C were lower than those in groups A and B (P < 0.05); the bladder function grade at 2 months after surgery was better in group C than in groups A and B (P < 0.05); the difference was not statistically significant when comparing the incidence of adverse reactions in the three groups (P > 0.05).Conclusion The combined use of pyridostigmine bromide and tamsulosin can effectively prevent and treat bladder dysfunction after radical hysterectomy, promote postoperative bladder function recovery, shorten the time of indwelling urinary catheter, improve urodynamics, and reduce the incidence of lower urinary tract/bladder infection, and did not significantly increase adverse reactions.
