BACKGROUND: The aim of this study is to evaluate differences in discomfort, complications and functional results after Retzius-sparing robot-assisted radical prostatectomy (RS-RARP) according to different urinary drainage: suprapubic tube (SPT) and standard urethral catheter (UC).
METHODS: Prospective, comparative, consecutive, non-randomized study. In all patients with a water-tight anastomosis, no hematuria, obesity, previous suprapubic surgery or history of bladder cancer, a SPT (two-way Foley 14-Fr catheter) was positioned instead of a Foley 18-Fr UC. One week after surgery, an institutional self-compiled questionnaire was administered. The patients were divided into two groups according to the presence of UC or SPT and were compared concerning pain, perioperative results, complications, functional outcomes.
RESULTS: Fifty-six patients with UC and 135 with SPT agreed to participate to the study. Median postoperative pain score was 3 (IQR: 2-5) in UC and 3 (IQR: 1-5) in SPT group (P=0.324); urinary drain-related pain scores were 3 (IQR: 1-5) in UC and 1 (IQR: 0-3) in SPT groups (P<0.001); catheter removal related scores were 1 (IQR: 0-3) and 1 (IQR: 1-3) (P=0.317), respectively. Lastly, 17.8% (UC) and 31.1% (SPT) wore a protection (small or medium pad) while the urinary drainage was in place (P=0.061). No differences related to complications were found (P=0.085); 7.9% of patients in UC group and 4.2% in SPT group (P=0.178) used pads one year after surgery.
CONCLUSIONS: We demonstrated suprapubic tube to be more comfortable than transurethral catheter after RARP, with a possible advantage concerning anastomotic postoperative problems.
