Abstract:
Objective:To investigate the efficacy and safety of en-bloc Holmium laser enucleation of the prostate (HoLEP) with an early apical mucosa dissection technique for the treatment of benign prostate hyperplasia (BPH).Methods:The clinical data of 215 patients treated with HoLEP for BPH from January 2020 to January 2023 in the Department of Urology, Beijing Friendship Hospital, Capital Medical University were retrospectively analyzed. According to different treatment methods, the patients were divided into study group ( n=112) and control group ( n=103). Patients in the study group were treated by the en-bloc HoLEP with an early apical mucosa dissection technique, while patients in the control group were treated by the classical two or three-lobes HoLEP. The primary endpoints included the rates of urinary incontinence at 1-month, 3-month, and 6-month after surgery in two groups of patients. The secondary endpoints included operative time, hemoglobin decrease, dissected prostate weight, postoperative indwelling catheter time, postoperative hospital stay, and international prostate symptom score (IPSS), quality of life (QoL), Qmax, and postvoid residual urine (PVR) at 3-month and 6-month after surgery. The measurement data were tested by Shapiro-Wilk normality test. The normal distribution of the measurement data were expressed as mean ± standard deviation ( ± s), and independent sample t-test was used for comparison between two groups. Measurement data of skewness distribution were expressed as median (interquartile distance) [ M( Q1, Q3)], and Wilcoxon or Mann-Whitney U test were used for comparison between two groups. The count data in the two groups were compared by the Chi-square test. Results:The incidence of urinary incontinence in the study group was 9.0% (10/112) and 3.6% (4/112) at 1-month and 3-month after surgery, which was significantly lower than those in the control group [18.5% (19/103) and 11.7% (12/103)], and the differences were statistically significant ( P< 0.05). Urinary incontinence in two groups recovered completely 6-month after surgery. The operation time of the study group was (68.74±23.71) min, which was lower than that of the control group [(88.04±25.43) min], and the difference was statistically significant ( P<0.05). There were no significant differences in hemoglobin decrease, dissected prostate weight, postoperative indwelling catheter time, postoperative hospital stay in the two groups ( P> 0.05). The IPSS, QoL, Qmax and PVR of the two groups were significantly improved at 3-month and 6-month after surgery ( P< 0.05), but there was no significant difference between the two groups ( P> 0.05). Conclusion:En-bloc HoLEP with an early apical mucosa dissection technique is safe and reliable in treating BPH, and has advantages over classic HoLEP in terms of short-term urinary continence rates, shortening operation time.
