Abstract:
Objective: To explore the learning curve of transurethral 450 nm blue light vaporization of the prostate (TUBVP) in a district hospital，in order to provide reference for clinicians who plan to perform TUBVP. Methods: The clinical data of 56 patients with benign prostatic hyperplasia (BPH) who received TUBVP performed by the same group of surgeons in Chang'an District Hospital during Jun. and Dec. 2023 were retrospectively analyzed. Cumulative sum (CUSUM) was used to fit the learning curve of ratio of volume to operating time (RVOT) of prostate volume /450 nm blue light. The learning curve was divided into different stages according to the inflection points，and the clinical data of patients operated at different stages were analyzed and compared. Results: The learning curve of TUBVP was 21 cases，including 1-21 cases in the learning stage，22-38 cases in the improvement stage and 39-56 cases in the maturity stage. With the increase of cases，the postoperative bladder irrigation time reduced \[40.00 (26.00，44.50) h vs. 23.00(20.50，34.00) h vs. 23.50(14.75，40.75) h\]，with statistical difference (P<0.05). The surgical efficiency increased \[(0.51±0.14) vs. (0.55±0.17) vs. (0.63±0.23)\]，while the reduction of hemoglobin \[(6.43±7.35) g/L vs. (5.65±10.91) g/L vs. (2.61±7.36) g/L\]，catheter indwelling time \[70.0 (66.0，106.0) h vs. 71.0 (66.0，89.0) h vs. 66.0 (58.5，78.5) h\]，and incidence of complications (9.5% vs. 5.9% vs. 0) in the three stages showed a gradually decreasing trend，but with no statistical significance (P>0.05). Conclusion: The learning curve of TUBVP is 21 cases. For clinicians in district hospitals，TUBVP is a worthy choice.
