[URINARY RETENTION FOLLOWING TRANSURETHRAL RESECTION OF THE BLADDER TUMOR].

We analyzed the incidence and risk factors associated with urinary retention following transurethral resection of the bladder tumors (TURBT). This retrospective study included a total of 218 TURBT cases we experienced from September 2021 to April 2023. Twenty-six patients (12%) experienced urinary retention after the procedure. The use of a thick urethral catheter (20 Fr or larger) post-surgery (p＝0.013) was identified as a significant risk factor. Of the 26 patients with urinary retention, 18 were able to recover spontaneous urination, while the remaining 8 required either permanent urethral catheter placement or intermittent catheterization. Healthcare professionals should be vigilant of urinary retention as a potential adverse event following TURBT.
