The comparison of transurethral versus suprapubic catheter after robot-assisted radical prostatectomy: A systematic review and meta-analysis

Background: The transurethral catheter (TUC) or supra-pubic catheter is commonly used after robotassisted radical prostatectomy (RARP). However, the best way of urine drainage after the operation is still controversial. Methods: A comprehensive search of PubMed, Cochrane, Web of Science databases and the reference lists of relevant articles was performed up to July 2019. This systematic review and meta-analysis was performed based on all randomized controlled trials (RCTs) and retrospective studies assessing the two techniques. Results: In total, nine studies (1,121 patients) were eligible, including three RCTs, one prospective and five retrospective studies. After RARP, postoperative pain was less in suprapubic catheter (SPC) group than TC group, both within 3 days [mean difference (MD): -0.70; 95% confidence interval (CI): -1.37 to -0.02; P=0.04] and 5 days after operation (MD: -0.96; 95% CI: -1.39 to -0.52; P<0.00001). There was no significant difference between SPC and TUC groups, in operation time (MD: 2.58; 95% CI: -5.82 to 10.97; P=0.55) and at rates of both catheterization-associated complication [odds ratio (OR): 1.05; 95% CI: 0.67 to 1.64; P=0.83] and long-term urinary incontinence (OR: 0.69; 95% CI: 0.42 to 1.12; P=0.13). Conclusions: Patients in SPC group suffer from less postoperative pain compared with the TUC group. SPC can be a better alternate of TUC.
