		                        			This study evaluated the association of periurethral calcification (PUC) with uroflowmetric parameters and symptom severity in male patients with lower urinary tract symptoms (LUTS) of benign prostatic hyperplasia (BPH). The data were collected from a prospectively maintained database of 1321 men with LUTS of BPH who visited Chonnam National University Hospital (Gwang-ju, Korea) from January 2015 to December 2019. PUC severity and location were evaluated on the midsagittal plane during transrectal ultrasonography. Relationships among age, prostate-related parameters, International Prostate Symptom Score (IPSS), and uroflowmetric parameters were assessed. Among the 1321 patients in this study, 530 (40.1%) had PUC. Patients with PUC had significantly higher IPSS (mean ± standard deviation [s.d.]: 15.1 ± 8.7 vs 13.1 ± 7.9; P < 0.001) and lower peak flow rate (Qmax; mean ± s.d.: 12.4 ± 6.6 ml s-1 vs 14.7 ± 13.3 ml s-1; P < 0.001), compared with patients who did not have PUC. Analyses according to PUC severity revealed that patients with severe PUC had higher prostate-specific antigen (PSA) level (P = 0.009), higher total IPSS (P < 0.001), lower Qmax (P = 0.002), and smaller prostate volume (P < 0.001), compared with patients who had non-severe (mild or moderate) PUC. Multivariate analysis showed that distal PUC was independently associated with high total IPSS (P = 0.02), voiding symptom score (P = 0.04), and storage symptom score (P = 0.023), and low Qmax (P = 0.015). In conclusion, PUC was significantly associated with worse LUTS parameters in terms of IPSS and Qmax. Furthermore, distally located PUC was independently associated with worse LUTS of BPH in men.

		                        			Enhanced recovery after surgery (ERAS) measures have not been systematically applied in transurethral surgery for benign prostatic hyperplasia (BPH). This study was performed on patients with BPH who required surgical intervention. From July 2019 to June 2020, the ERAS program was applied to 248 patients, and the conventional program was applied to 238 patients. After 1 year of follow-up, the differences between the ERAS group and the conventional group were evaluated. The ERAS group had a shorter time of urinary catheterization compared with the conventional group (mean ± standard deviation [s.d.]: 1.0 ± 0.4 days vs 2.7 ± 0.8 days, P < 0.01), and the pain (mean ± s.d.) was significantly reduced through postoperative hospitalization days (PODs) 0-2 (POD 0: 1.7 ± 0.8 vs 2.4 ± 1.0, P < 0.01; POD 1: 1.6 ± 0.9 vs 3.5 ± 1.3, P < 0.01; POD 2: 1.2 ± 0.7 vs 3.0 ± 1.3, P < 0.01). No statistically significant difference was found in the rate of postoperative complications, such as postoperative bleeding (P = 0.79), urinary retention (P = 0.40), fever (P = 0.55), and readmission (P = 0.71). The hospitalization cost of the ERAS group was similar to that of the conventional group (mean ± s.d.: 16 927.8 ± 5808.1 Chinese Yuan [CNY] vs 17 044.1 ± 5830.7 CNY, P =0.85). The International Prostate Symptom Scores (IPSS) and quality of life (QoL) scores in the two groups were also similar when compared at 1 month, 3 months, 6 months, and 12 months after discharge. The ERAS program we conducted was safe, repeatable, and efficient. In conclusion, patients undergoing the ERAS program experienced less postoperative stress than those undergoing the conventional program.

		                        			OBJECTIVES:
		                        			To evaluate the feasibility and safety of bipolar-plasmakinetic transurethral enucleation and resection of the prostate (B-TUERP) in day surgery.
		                        		
		                        			METHODS:
		                        			From January 2021 to August 2022, 34 patients with benign prostatic hyperplasia (BPH) underwent B-TUERP in day surgery in the First Affiliated Hospital of Anhui Medical University. Patients completed the screening and anesthesia evaluation before admission and received the standard surgery which implements "anatomical enucleation of the prostate" and "absolute bleeding control" on the same day of admission, and by the same doctor. Bladder irrigation was stopped, catheter was removed and the discharge evaluation was performed on the first day after operation. The baseline data, perioperative conditions, time of recovery, treatment outcomes, hospitalization costs, and postoperative complications were analyzed.
		                        		
		                        			RESULTS:
		                        			All operations were successfully conducted. The average age of the patients was (62.2±7.8) years, average prostate volume was (50.2±29.3) mL. The average operation time was (36.5±19.1) min, the average hemoglobin and blood sodium were decreased by (16.2±7.1) g/L and (2.2±2.0) mmol/L, respectively. The average postoperative length of hospital stay, and total length of hospital stay were (17.7±2.2) and (20.8±2.1) h, respectively, and the average hospitalization cost was (13 558±2320) CNY. All patients were discharged on the day after surgery except for one patient who was transferred to a general ward. Three patients received indwelling catheterization after catheter removal. The 3-month follow-up results showed a substantial improvement in the International Prostate Symptom Score, quality of life score and maximum urinary flow rate (all P<0.01). Three patients experienced temporary urinary incontinence, 1 patient experienced urinary tract infection, 4 patients were diagnosed with urethral stricture and 2 patients experienced bladder neck contracture. No complications above Clavien grade Ⅱ occurred.
		                        		
		                        			CONCLUSIONS
		                        			The preliminary results showed that B-TUERP ambulatory surgery is a safe, feasible, economical and effective treatment for appropriately selected patients with BPH.

		                        			OBJECTIVES:
		                        			To investigate the effect of progressive pre-disconnection of urethral mucosal flap during transurethral plasmakinetic enucleation of prostate (TUPEP) on early recovery of urinary continence.
		                        		
		                        			METHODS:
		                        			Clinical data of patients with benign prostatic hyperplasia (BPH) admitted in Zhujiang Hospital of Southern Medical University during February and May 2022 were collected. All the patients underwent TUPEP, and the progressive pre-disconnection of urethral mucosal flap was performed in the procedure. The total operation time, enucleation time, postoperative bladder irrigation time and catheter indwelling time were recorded. Urinary continence was evaluated 24 h, 1 week, and 1, 3, 6 months after the removal of urinary catheter.
		                        		
		                        			RESULTS:
		                        			All surgeries were successfully completed at one time with less intraoperative bleeding, and there were no complications such as rectal injury, bladder injury or perforation of prostate capsule. The total operation time was (62.2±6.5) min, the enucleation time was (42.8±5.2) min, the postoperative hemoglobin decrease by (9.5±4.5) g/L, the postoperative bladder irrigation time was (7.9±1.4) h, and the postoperative catheter indwelling time was 10.0 (9.2, 11.4) h. Only 2 patients (3.6%) had transient urinary incontinence within 24 h after catheter removal. No urinary incontinence occurred at 1 week, and 1, 3, 6 months after operation, and no safety pad was needed. The Qmax at 1 month after operation was 22.3 (20.6, 24.4) mL/s, international prostate symptom scores were 8.0 (7.0, 9.0), 5.0 (4.0, 6.0) and 4.0 (3.0, 4.0) at 1, 3 and 6 months after surgery, and quality of life scores at 1, 3 and 6 months after surgery were 3.0 (2.0, 3.0), 2.0 (1.0, 2.0) and 1.0 (1.0, 2.0), all of these indicators were better than those before surgery (all P<0.01).
		                        		
		                        			CONCLUSIONS
		                        			In the treatment of BPH, the application of progressive pre-disconnection of urethral mucosal flap in TUPEP can completely remove the hyperplastic glands and promote early recovery of postoperative urinary continence with less perioperative bleeding and decreased surgical complications.

		                        			Benign prostatic hyperplasia (BPH) is the most common cause of lower urinary tract symptoms in men. When drug treatment is ineffective or conventional surgery is not suitable, novel minimally invasive therapies can be considered. These include prostatic urethral lift, prostatic artery embolisation, water vapor thermal therapy, Aquablation-image guided robotic waterjet ablation, temporary implantable nitinol device and prostatic stents. These novel therapies can be performed in outpatient setting under local anesthesia, with shorter operative and recovery times, and better protection of ejaculatory function and erectile function. General conditions of the patient and advantages and disadvantages of the each of these therapies should be fully considered to make individualized plans.

		                        			A total of 60 patients with mild to moderate BPH of kidney yang deficiency were randomly divided into an observation group (30 cases, 3 cases dropped off) and a control group (30 cases, 4 cases dropped off). The observation group was treated with fire needling at Guanyuan (CV 4), Shuidao (ST 28) and Qugu (CV 2) twice a week (2-3 d interval between each treatment), continuous treatment for 4 weeks. The control group received lifestyle advice and education, once a week for 4 weeks. In the two groups, the international prostate symptom score (IPSS), the quality of life (QoL) score and the average daily number of nightly urination were observed before treatment, after treatment and during the follow-up of the 4th week; the urinary maximum flow rate (Qmax), the average flow rate (Qave), and the prostate volume were assessed before and after treatment in the two groups. The safety was observed in the observation group.
		                        		
		                        			RESULTS:
		                        			After treatment and during follow-up, the IPSS scores, QoL scores, and the average daily number of nightly urination in the observation group were decreased compared with those before treatment (P<0.05), and those in the observation group were lower than the control group (P<0.05). After treatment, there was no significant difference in Qmax, Qave and prostate volume between the two groups and within the each group (P>0.05). There were no fire needling-related adverse reactions, and no obvious abnormality was found in urine routine and coagulation function tests before and after treatment in the observation group.
		                        		
		                        			CONCLUSION
		                        			Fire needling can improve lower urinary tract symptoms and quality of life, reduce frequency of nightly urination in patients with mild to moderate BPH of kidney yang deficiency, and has good safety.

		                        			A cross-sectional study was conducted to estimate the age-stratified normal levels and age-related changes in the risk predictors of benign prostatic hyperplasia (BPH) progression. A total of 4706 male participants aged 40 years or older in Zhengzhou (China) were enrolled. The values of the International Prostate Symptom Score (IPSS), prostate-specific antigen (PSA), prostate volume (PV), and postvoid residual urine volume (PVR) significantly increased with age. Nonlinear relationships between age and IPSS scores ≥8 (P for nonlinearity = 0.046), PSA level ≥1.6 ng ml-1, PV ≥31 ml, or PVR ≥39 ml (all P for nonlinearity <0.001) were observed. After the age of 61 years, the risk indicators related to BPH progression were positively correlated with age (odds ratio [OR] >1), regardless of the predictors of the IPSS score, PSA level, PV, or PVR; and the OR values increased gradually. Therefore, after the age of 61 years, the risk predictors related to BPH progression were positively correlated with age.

		                        			The aim of this study was to explore the optimal timing of holmium laser enucleation of the prostate (HoLEP) in patients presenting benign prostatic hyperplasia (BPH) with lower urinary tract symptoms (LUTS). A retrospective analysis was conducted based on the perioperative and postoperative outcome data of 1212 patients who underwent HoLEP in Shanghai Ninth People's Hospital (Shanghai, China) between January 2009 and December 2018. According to the preoperative International Prostate Symptom Score (IPSS), all patients whom we analyzed were divided into Group A (IPSS of 8-18) and Group B (IPSS of 19-35). Peri- and postoperative outcome data were obtained during the 1-year follow-up. IPSS changes were the main postoperative outcomes. The postoperative IPSS, quality of life, peak urinary flow rate, postvoid residual, and overactive bladder symptom score (OABSS) improved significantly. The IPSS improved further in the group with severe LUTS symptoms, but the postoperative IPSS was still higher than that in the moderate LUTS group. OABSSs showing moderate and severe cases after follow-up were more frequent in Group B (9.1%) than in Group A (5.2%) (P < 0.05). There were no significant intergroup differences in the intraoperative American Society of Anesthesiologists or hospitalization expense scores, and the medication costs, as well as the total costs, were significantly higher in Group B. In this retrospective study, HoLEP was an effective treatment for symptomatic BPH. For patients with LUTS, earlier surgery in patients with moderate severity may result in a marginally better 12-month IPSS than that in men with severe symptoms.

		                        			This study aimed to compare the predictive value of six selected anthropometric indicators for benign prostatic hyperplasia (BPH). Males over 50 years of age who underwent health examinations at the Health Management Center of the Second Xiangya Hospital, Central South University (Changsha, China) from June to December 2020 were enrolled in this study. The characteristic data were collected, including basic anthropometric indices, lipid parameters, six anthropometric indicators, prostate-specific antigen, and total prostate volume. The odds ratios (ORs) with 95% confidence intervals (95% CIs) for all anthropometric parameters and BPH were calculated using binary logistic regression. To assess the diagnostic capability of each indicator for BPH and identify the appropriate cutoff values, receiver operating characteristic (ROC) curves and the related areas under the curves (AUCs) were utilized. All six indicators had diagnostic value for BPH (all P ≤ 0.001). The visceral adiposity index (VAI; AUC: 0.797, 95% CI: 0.759-0.834) had the highest AUC and therefore the highest diagnostic value. This was followed by the cardiometabolic index (CMI; AUC: 0.792, 95% CI: 0.753-0.831), lipid accumulation product (LAP; AUC: 0.766, 95% CI: 0.723-0.809), waist-to-hip ratio (WHR; AUC: 0.660, 95% CI: 0.609-0.712), waist-to-height ratio (WHtR; AUC: 0.639, 95% CI: 0.587-0.691), and body mass index (BMI; AUC: 0.592, 95% CI: 0.540-0.643). The sensitivity of CMI was the highest (92.1%), and WHtR had the highest specificity of 94.1%. CMI consistently showed the highest OR in the binary logistic regression analysis. BMI, WHtR, WHR, VAI, CMI, and LAP all influence the occurrence of BPH in middle-aged and older men (all P ≤ 0.001), and CMI is the best predictor of BPH.

		                        			Benign prostatic hyperplasia is caused by kidney deficiency and impaired qi transformation of the urinary bladder and is manifested by the stagnation of essence chamber. Based on jingjin (muscle region of meridian, sinew/fascia) theory and taking the visceral membrane as the principal, acupuncture is delivered at sinew/fascia to promote qi circulation, resolve stasis and open the orifice. Guided by CT, the needle is inserted at Zhongji (CV 3), the front-mu point of the urinary bladder, and then goes to the prostatic capsule, meaning "the disease of zang organ is treated by needling the front-mu point". In treatment of benign prostatic hyperplasia, this acupuncture therapy stimulates the different layers of fascia, by which, the defensive qi on the exterior is regulated and "essence orifice" in the interior is adjusted so that the urination can be promoted.
