Analysis of Clavien-Dindo classification and risk factors for complications after transurethral Thulium Laser enucleation of the prostate.

This study aimed to investigate the risk factors for postoperative complications following transurethral thulium laser enucleation of the prostate (ThuLEP) and provide references for reducing the occurrence of postoperative complications. A retrospective analysis was conducted on 103 patients with benign prostate hyperplasia who underwent ThuLEP from September 2020 to August 2022. Among them, 95 patients had complete clinical and follow-up data. Clinical data and follow-up information of the patients were collected. Univariate and multivariate logistic regression analyses were performed to identify the influencing factors of postoperative complications following ThuLEP. The incidence of postoperative complications following ThuLEP was 11.58% (11/95), among which the rates of Grade I, II, and III complications were 3.16% (3/95), 3.16% (3/95), and 5.29% (5/95), respectively. The prostate volume after ThuLEP was 96.11 ± 43.38 ml in the uncomplication group and 139.71 ± 96.41 ml in the complication group, and there was a statistically significant difference between the 2 groups (P = .02). The prostate mass after ThuLEP was 46.99 ± 22.14 ml in the uncomplication group and 70.25 ± 41.37 ml in the complication group, and there was a statistically significant difference between the 2 groups (P = .01). The postoperative catheter removal time after ThuLEP was 3 ± 1.04 days in the uncomplication group and 2 ± 1.49 days in the complication group, and there was a statistically significant difference between the 2 groups (P = .02).Univariate and multivariate logistic regression analyses revealed that the postoperative catheter removal time (P = .046) was an independent risk factor for Grade II-III complications after ThuLEP. Prostate volume and prostate mass are influencing factors for postoperative complications following ThuLEP. Postoperative catheter removal time is an independent risk factor for postoperative complications following ThuLEP.
