Introduction: The aim of this study was to compare the perioperative outcomes of routine drainage insertion vs. no drainage in patients undergoing robot-assisted radical prostatectomy (RARP), robot-assisted partial nephrectomy (RAPN), and robot-assisted radical cystectomy (RARC). Evidence acquisition: A literature search was conducted through April 2022 using PubMed/Medline, Embase, and Web of Science databases. Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines were followed to identify eligible studies. Evidence synthesis: Eleven studies comprising 8447 RARPs and 1890 RAPNs met our inclusion criteria. Our search strategy did not identify any studies within the RARC framework. In RARP, patients without postoperative drainage had lower rate of postoperative ileus (OR 0.53, 95% CI: 0.38 to 0.74; P<0.001) and similar low-grade (Clavien 1-2, P=0.41) and high-grade (Clavien ≥3; P=0.85) complications, urinary leakage (P=0.07), pelvic hematoma (P=0.35), symptomatic lymphocele (P=0.13), fever (P=0.25), incisional hernia (P=0.31), reintervention (P=0.57), length of hospital stay (P=0.22), and readmission (P=0.74) compared with routinely drained patients. In RAPN, patients without postoperative drainage had shorter length of hospital stay (mean difference: -0.84 days, 95% CI: -1.06 to -0.63; P<0.001) and similar low-grade (P=0.94) and high-grade (P=0.31) complications, urinary leakage (P=0.49), hemorrhage (P=0.39), reintervention (P=0.69), and readmission (P=0.20) compared with routinely drained patients. Conclusions: In our study, patients without drainage had similar perioperative course to patients with prophylactic drain insertion after RARP and RAPN. Omission of drain insertion was associated with a lower rate of postoperative ileus for RARP and a shorter hospital stay for RAPN. In the era of robotic surgery, routine drain placement is no longer indicated in unselected patients.
