Evaluation of the functional results and safety of early removal of the urethral catheter after laparoscopic radical prostatectomy

Abstract

Background. Currently, there is no single point of view on the timing of safe removal of the urethral catheter in patients who have undergone laparoscopic radical prostatectomy.Objective of the study: to evaluate the safety and functional results of early removal of the urethral catheter after laparoscopic radical prostatectomy.Materials and methods. In the period from January 2020 until April 2021, the study included 100 patients with a diagnosis of prostate cancer who underwent laparoscopic radical prostatectomy by one surgeon. Patients were divided into 2 groups. Group A (n = 50) included patients with the urethral catheter removed on the second day after surgery. Group B (n = 50) – the control group – included patients with standard catheter removal (14 days).Results. According to the results of cystography, in group A extravasation of a contrast agent from the zone of urethrovesical anastomosis was determined in 3 (6 %) cases. Seven (14 %) patients developed acute urinary retention after the removal of the urethral catheter. Among 2 patients acute urinary retention occurred immediately after catheter removal. In 5 cases acute urinary retention developed 2–7 days after catheter removal. These patients underwent repeated catheterization for a period of 2–3 days. In our study, removal of the urethral catheter on the second day increased the dynamic of restoring urinary continence in the postoperative period. The frequency of complete recovery of urinary continence (0–1 pad per day) in the groups A and B, respectively, was: after 1 month – 22 and 16 %, after 6 months – 64 and 54 %, after 12 months – 78 and 78 %. Urinary incontinence in the groups A and B was as follows: mild (2–3 pads per day): after 1 month – 40 and 34 %, after 6 months – 30 and 32 %, after 12 months – 20 and 18 %; moderate (4–5 pads per day): after 1 month – 20 and 26 %, after 6 months – 6 and 10 %, after 12 months – 2 and 2 %; severe (6 pads or more): after 1 month – 18 and 24 %, after 6 months – 0 and 4 %, after 12 months – 0 and 2 %.Conclusion. Early removal of the urethral catheter (2 days) in patients who underwent laparoscopic radical prostatectomy is a relatively safe method that improves the restoration of urinary continence.
