Introduction. The main question of the surgeon in the postoperative period is the possibilities of assessing the function of the lower urinary tract. Symptomatic assessment of urination disorders does not allow to diagnose since many symptoms are subjective and non-specific for a particular disease. Urodynamic study allows to assess the state of the urinary system and determine further tactics. Methods and materials. The study included 173 patients with morphologically verified cervical cancer IB1-IIB stages who underwent radical hysterectomy (RH). The main group consisted of 26 patients after RH type С1 using the water-jet technique. The comparison group A included 79 patients who underwent RH type С1 with the traditional technique. The comparison group B included 52 patients who accepted radical hysterectomy RH type C2. All patients underwent uroflowmetry at the preoperative and postoperative stages in order to exclude dysfunction of the lower urinary tract. Results. In a comparative study of the parameters of uroflowmetry before surgery and 2 months after surgical treatment in patients of the main group, significant differences were obtained in such parameters as the average and maximum velocity of urine flow. In control group A, statistically significant differences were obtained in such parameters as the average urine flow rate, maximum urine flow rate, urine flow time, and the volume of residual urine. In control group B, all indicators had significant differences, with the exception of the volume of urine excreted. Conclusion. Comparative results before surgery and 2 months after surgical treatment in the main group indicate the advantage of the water jet dissection technique as the most precise and nerve-sparing method.
