Abstract

Purpose: To assess whether the 5-item Frailty Index (5i-FI) predicts surgical complications of endoscopic surgery for benign prostatic obstruction (BPO) and examine the rates of these complications across BPO surgical modalities adjusting for patient frailty.

Methods: The ACS-NSQIP registry was queried for patients who underwent transurethral resection of the prostate (TURP), photoselective vaporization of the prostate (PVP), and laser enucleation of the prostate (LEP) between 2009 and 2019. Patients' frailties were estimated using the 5i-FI. We assessed the association between 5i-FI and the following endpoints: all complications, major complications (Clavien-Dindo ≥ 3), length of stay (LOS) ≥ 2 days, and 30-day postoperative readmission. Inverse probability of treatment weighting (IPTW) was used to account for selection bias in treatment allocation. IPTW-adjusted rates for 30-day complications were compared between surgical modalities.

Results: The cohort included 38,399 (62.6%) TURP, 19,121 (31.2%) PVP, and 3797 (6.2%) LEP. Men with 5i-FI score ≥ 2 were more likely to receive TURP (22.7%) and PVP (22.5%) than LEP (18.8%). 5i-FI ≥ 2 was associated with higher odds of all complications (OR 1.50), major complications (OR 1.63), LOS ≥ 2 (OR 1.31), and readmission (OR 1.65). After IPTW, LEP had the lowest rates for all complications (6.29%; 95%CI 5.48-7.20), major complications (2.30%; 95%CI 1.83-2.89), and readmission (3.80%; 95%CI 3.18-4.53).

Conclusion: The 5i-FI score is an independent predictor of 30-day postoperative surgical complications after endoscopic BPO surgery. After IPTW, LEP and PVP were associated with lower rates of complications than TURP. However, frail patients were less likely to undergo PVP and LEP. Preoperative frailty assessment could improve risk stratification before BPO surgery.
