[Effect of transurethral thuliumlaser vapoenucleation of the prostate with low-power conventional pulse mode on sexual function in patients with benign prostatic hyperplasia].

ABSTRACT

OBJECTIVE: To explore the effect of a novel transurethral thulium laser vapoenucleation of the prostate with low-power conventional pulse mode (LP-ThuVEP) on sexual function in patients with benign prostatic hyperplasia (BPH). METHODS: 89 BPH patients admitted to Department of Urology, Jintan People's Hospital, Affiliated to Jiangsu University, from January 2022 to June 2023 were selected and randomly divided into the LP-ThuLEP group (45 cases) and the transurethral plasma kinetic resection of the prostate (TUPKRP) group (44 cases). Perioperative indicators were recorded, and the IPSS, Qmax, Qavg, PVR, and QoL of the two groups of patients before surgery and 3 months and 6 months after surgery were comparatively analyzed. The effect of surgery on male sexual function was evaluated through the International Index of Erectile Function-5 (IIEF-5) score and the Male Sexual Health Questionnaire-Ejaculatory Dysfunction (MSHQ-EjD) score. RESULTS: Compared with the TUPKRP group, the LP-ThuVEP group had no statistically significant difference in operation time (P>0.05), but there were statistical differences in bladder irrigation time and indwelling urinary catheter time (P<0.05) and significant statistical differences in the decrease in hemoglobin on the day of surgery and the disappearance time of gross hematuria induced by defecation after surgery (P<0.001). The perioperative complications of the two groups were comparable. Among the urinary tract symptom indicators, the LP-ThuVEP group had statistically significant differences in IPSS score, QoL score, and PVR compared with the TUPKRP group 3 months after surgery (P<0.05). In terms of male sexual function, there was a statistical difference in IIEF-5 scores between the two groups at 3 months and 6 months after surgery (P<0.05); Except that there was no statistical difference in the ejaculation-related satisfaction scores between the two groups at 3 months after surgery (P>0.05), there had all significant statistical differences in ejaculation function and satisfaction scores between and within the groups at 3 months and 6 months after surgery (P<0.001). CONCLUSION: Compared with TUPKRP, the LP-ThuVEP can also effectively relieve urinary tract obstruction caused by BPH and has the advantages of less damage and faster recovery of erectile function and ejaculatory function of patients.
