Retrospective analysis of second-generation bipolar transurethral vaporization of the prostate in older patients aged ≥80 years with benign prostate enlargement
Abstract
Background:: To investigate the treatment outcomes and postoperative complications of second-generation bipolar transurethral vaporization of the prostate (B-TUVP) using an oval-shaped electrode in older patients aged ≥80 years with benign prostatic enlargement (BPE). Materials and Methods:: Second-generation B-TUVP was performed in male patients with lower urinary tract symptoms (LUTS) or urinary retention between July 2018 and August 2021. Patient characteristics and surgical outcomes were retrospectively compared between patients aged <80 and ≥80 years. Results:: A total of 178 patients with BPE who underwent B-TUVP at Yokosuka Kyosai Hospital were enrolled in this study with six months follow-up. For catheterized patients, improvement in uroflowmetric outcomes and patient reported outcomes (PROs) were almost equivalent between those <80 and ≥80 years of age. Achievement of a catheter-free status after B-TUVP was higher in patients aged <80 years (87.2%) than those aged ≥80 years (69.2%); however, there was no statistical significance (P= 0.061). Postoperative prolonged hematuria and fever were significantly more frequent in patients aged ≥80 years than in those <80 years. Age (≥80 years) and operative duration (≥100 min) were independent and significant predictors of postoperative complications of B-TUVP. Conclusion:: This study is the first to demonstrate that B-TUVP showed almost equivalent uroflowmetric outcomes and PROs in patients aged <80 and ≥80 years with BPE. Age of ≥80 years was associated with higher postoperative complications after B-TUVP, which suggests that B-TUVP should be performed within 100 min to minimize postoperative complications, such as prolonged hematuria and fever.
