Complication rate across the minimally invasive surgical treatments (MISTs): where do we stand? A systematic review of the literature.

Over the past decade, the range of surgical options to benign prostatic obstruction (BPO) has expanded significantly with the advent of minimally invasive surgical therapies (MISTs). Nevertheless, the available evidence in the field is heterogeneous. Efficacy and safety thresholds are yet to be determined.

To evaluate perioperative and long-term complications after MISTs - including Aquablation, steam injection (Rezūm), Transperineal laser ablation of the prostate (TPLA), implantation of a prostatic urethral lift (PUL) and temporary implantable nitinol device (iTIND) - in patients with lower urinary tract symptoms due to BPO.

A systematic literature search was conducted in January 2024 using Medline (via PubMed), Embase (via Ovid), Scopus, and Web of Science. The search strategy used PICO criteria (Patients, Interventions, Comparisons, Outcomes) [1], focusing specifically on patients with BPH-associated LUTS who underwent MIST or other comparative treatments, aiming to assess both perioperative and long-term safety outcomes. Article selection was conducted in accordance with the PRISMA guidelines. The risk of bias and the quality of the articles included were assessed. A dedicated data extraction form was used to collect the data of interest.

The initial electronic search identified 3660 records, of which 24 ultimately met the inclusion criteria and were included in the analysis. Overall, Aquablation was associated with a higher major complications rate of 14% (IQR 6-22), particularly in the case of patients with prostates <70 ml. PUL showed a higher early postoperative acute urinary retention rate (10.9%, IQR 9.2-12.3%), while 1.4% of patients treated with iTIND experienced major perioperative complications. Urinary tract infections were mostly reported in series assessing TPLA and Rezūm.

The adoption of MISTs for LUTS due to BPH is associated with a varied spectrum of perioperative and long-term complications. Our findings showed an acceptable safety profile with specific complications dependent on the type of MIST performed, highlighting the importance of individualized patient selection and procedure-specific considerations.
