Abstract:Objective To evaluate the perioperative safety and feasibility of day-case transurethral holmium laser enucleation of prostate (HoLEP) under over-night mode.Method From January 2021 to March 2023, 83 patients of benign prostatic hyperplasia (BPH) were elected and treated with HoLEP by the one surgeon. According to different management methods, these patients were divided into the over-night day-case HoLEP group and the ordinary HoLEP group. Again, these patients were divided into large volume (≥ 50 mL) group and small volume ( < 50 mL) group according to the prostate volume. Record the age and perioperative data of all patients [total prostate volume, prostate resection weight, proportion of prostate resection, operating time, changes in peripheral venous blood hemoglobin (Hb), bladder flushing duration, catheter insertion duration, and success rate of first tube removal], the parameters of each group were compared.Result All of the 83 patients undergoing HoLEP surgery in this study, and there were no cases of HoLEP related reoperation or readmission. Among them, there were 43 cases in the over-night HoLEP group, aged 57~90 with an average of (70.1 ± 7.3) years old, and the prostate volume was 29~161 mL with an average of (63.0 ± 28.8) mL, All of them were discharged within 24 h, and there were no cases transferred to the ordinary HoLEP group, the success rate of first tube removal was 88.4% (38/43), and with average catheterization duration was (17.8 ± 3.6) h; The other 40 cases were included into the ordinary HoLEP group, aged 55 ~ 87 with an average of (70.4 ± 8.2) years old, the volume of the prostate was 22 ~ 118 mL with an average of (59.4 ± 29.0) mL, the success rate of first tube removal was 90.0% (36/40), and with average catheterization duration was (77.5 ± 25.1) h; There was no statistically significant difference in the perioperative parameters (total prostate volume, prostate resection weight, proportion of prostate resection, operating time, changes in peripheral venous blood Hb, and bladder flushing time) between the two groups (P > 0.05), while the difference in catheter duration was statistically significant (P < 0.01).Conclusion Regardless of the size of the prostate volume, day-case HoLEP is safe and feasible. Day-case HoLEP under the over-night mode is suitable for widespread and routine implementation in China, especially in medical centers with rich experience of HoLEP.
