Prolonged indwelling catheter time after RARP does not lead to follow-up surgery

Indwelling catheterization following radical prostatectomy is used to aid healing and urinary drainage. While early removal is well investigated, prolonged catheterization has only been investigated in terms of urinary incontinence. Other complications such as anastomotic strictures are unexplored so far. This study aims to analyze the sequelae of catheterization lasting more than 14 days after robotic-assisted radical prostatectomy (RARP).

A prospective database of 3087 patients undergoing RARP was analyzed, focusing on 180 patients with catheterization exceeding 14 days (Group A) and 88 matched controls (Group B). Outcome measures included subsequent surgeries, complications, and functional outcomes.

Prolonged catheterization did not significantly increase the need for subsequent surgeries (6% in Group A vs. 7% in Group B, p = .95). However, anastomotic strictures were more common in Group A (3%) compared to Group B (0%) after exclusion of risk factors. Incontinence rates were similar between groups, although a subgroup analysis revealed higher incontinence rates in patients with catheterization exceeding 28 days. No significant differences were observed in erectile function or quality of life between the groups.

Prolonged catheterization after RARP does not independently increase the risk of anastomotic strictures in the general population. However, in patients without risk factors, prolonged catheter dwell time may elevate the risk of strictures and subsequent surgeries. Additionally, patients with catheterization exceeding 28 days may experience higher rates of long-term incontinence. Further studies with larger sample sizes are needed to confirm these findings and elucidate the long-term implications of prolonged catheterization.
