Objective:To investigate the efficacy and safety of percutaneous trans-hepatic choledochoscopic lithotripsy (PTCSL) in the treatment of recurrent hepatobiliary calculi under enhanced recovery after surgery (ERAS) mode.Methods:Clinical data of 88 patients with recurrent hepatobiliary calculi, who were treated with PTCSL at Zhengzhou Central Hospital Affiliated to Zhengzhou University and the First Affiliated Hospital of Xi'an Jiaotong University between June 2022 and June 2024 were retrospectively analyzed, including 34 males and 54 females, aged (52.0±13.8) years. The scheme includes preoperative education, prophylactic antibiotic application, ensuring the quality of surgery, early postoperative feeding and activity, etc. The operation can be divided into two fashions: percutaneous transhepatic cholangial drainage and PTCSL, which can be completed in one stage (one-stage expansion method) or in two stages (staged expansion method). Clinical data such as gender, age, operative time, intraoperative blood loss, residual stone, and surgical complications were recorded.Results:All 88 patients underwent PTCSL under ERAS mode successfully, including 52 cases using one-stage expansion method and 36 cases using staged expansion method. The operative time was (53±20) min, the intraoperative blood loss was (9.7±3.8) ml, the postoperative hospital stay was (3.6±1.7) d, and the hospitalization cost was (17 500±4 700) yuan. Sixty-nine patients (78.4%, 69/88) had one-time stone removal in the first PTCSL. A total of 19 cases of residual stones were managed again by percutaneous sinus soft choledochoscopy, of which 12 cases were managed by one-time choledochoscopy, five cases by two-time choledochoscopy, and two cases by three-time choledochoscopy. The rate of residual stone was significantly higher in one-stage expansion method compared to staged expansion method [28.8% (15/52) vs. 11.1% (4/36), P=0.040]. No death, conversion to open surgery, or severe complications such as intra-abdominal hemorrhage or bile leakage occurred in the patients. No residual stones or recurrence were found during the follow-ups of (7.5±2.1) months after discharge. Conclusion:PTCSL under ERAS mode is safe and effective in the treatment of recurrent hepatobiliary calculi.

Objective: To investigate the clinical efficacy of transurethral 450 nm blue laser vaporization of prostate (BVP) and transurethral plasmakinetic resection of the prostate (PKRP) in the treatment of frail elderly patients with benign prostatic hyperplasia (BPH). Methods: A retrospective analysis was conducted on the clinical data of 62 frail elderly BPH patients undergoing BVP (n=32) or PKRP (n=30) in our hospital during Jan.2023 and Jun.2024.The two groups were compared in terms of postoperative hemoglobin drop, operation time, hospital stay, catheter indwelling time, bladder irrigation time, preoperative and postoperative 3-month postvoid residual (PVR), maximum urinary flow rate (Qmax), international prostate symptom score (IPSS), quality of life score (QoL), and postoperative complications. Results: The postoperative hemoglobin drop was lower in the BVP group than in the PKRP group [(1.62±1.04) g/L vs.(7.37±2.37) g/L, P＜0.001].The operation time [(24.53±7.52) min vs. (47.77±11.12) min], hospital stay [(2.78±1.62) d vs. (8.13±0.82) d], catheter indwelling time [(1.84±0.99) d vs. (5.40±0.81) d], and bladder irrigation time [(7.37±2.35) h vs. (51.60±19.72) h] were significantly shorter in the BVP group than in the PKRP group (all P＜0.001).At 3 months postoperatively, both groups showed significant improvements in IPSS, QoL, Qmax, and PVR compared to preoperative levels (P＜0.05), but there were no significant differences between the two groups (P>0.05).The overall incidence of early postoperative complications in the BVP group was lower than that in PKRP group (18.75% vs. 43.33%, P＜0.05).After 3 months of follow-up, there was no significant difference in the incidence of complications between the BVP group and PKRP group(3.13% vs. 13.33%, P=0.14). Conclusion: BVP for the treatment of frail elderly BPH patients is safe and reliable, associated with minimal bleeding, short operation time, catheterization time and hospital stay, and there is no need to discontinue anticoagulant drugs.

Objective To evaluate the diagnostic value of prostate health index(PHI)and prostate health index density(PHID)in identifying intermediate-to high-risk prostate cancer(PCa).Methods Clinical data of 160 treatment-na?ve patients with highly suspected PCa,who underwent initial prostate biopsy in our hospital during Jul.2022 and Feb.2024,were retrospectively analyzed.Data included age,body mass index(BMI),prostate volume(PV),total prostate-specific antigen(tPSA),free PSA(fPSA),[-2]proPSA(p2PSA),PHI and PHID.Biopsy-positive results were stratified according to the EAU D'Amico risk criteria.Receiver operating characteristic(ROC)curve and multivariate logistic regression analysis were employed to assess the diagnostic performance of PHI and PHID in predicting PCa and identifying intermediate-to high-risk PCa.Results There were statistically significant differences in tPSA,p2PSA,PHI and PHID between the negative and positive groups,as well as among the low-,medium-and high-risk groups(P＜0.01).Both PHI and PHID demonstrated good diagnostic performance in predicting PCa(AUC=0.820 8 and 0.875 7,respectively;all P＜0.001),and in identifying intermediate-to high-risk PCa(AUC=0.838 0 and 0.878 3,respectively;all P＜0.001).Compared to the baseline model,the incorporation of PHI and PHID individually into the multivariate model significantly improved the screening performance for PCa(AUC=0.910 and 0.898,respectively;all P＜0.001).Conclusion PHI and PHID exhibit high diagnostic efficacy in screening PCa,particularly in identifying intermediate-to high-risk disease.

【Objective】 To investigate the effects of radical prostatectomy (RP) or brachytherapy (BT) on the prognosis of patients with high-risk prostate cancer as initial treatment, in order to provide a reference for the selection of clinical treatment options. 【Methods】 The clinical data of 133 191 patients diagnosed with high-risk prostate cancer and treated with RP or BT during 2005 and 2014 were extracted from the SEER database.The 5-year and 10- year cancer-specific survival (CSS) and overall survival (OS) were compared with K-M analysis and univariate and multivariate Cox regression.The clinical data of another 253 patients diagnosed with high-risk prostate cancer in Subei People’s Hospital during 2015 and 2020 were collected, including 153 patients who received RP and 100 patients who received BT.The 5-year biochemical progress-free survival (bPFS) and CSS were compared with K-M analysis. 【Results】 Univariate analysis of SEER data showed that BT was associated with a higher risk of death (HR=1.319, 95%CI: 1.256-1.386, P<0.001); age, marital status and TNM stage were associated with higher risk of death (P<0.001).Multivariate analysis, adjusted for relevant variables, showed that BT did not result in a higher risk of death compared with RP (HR=0.964, 95%CI:0.924-0.996, P=0.808). The OS curve showed that the longer the observed survival time, the better OS of RP as compared to BT (P<0.001); however, the CSS survival curve showed that the longer the observed survival time, the better CSS of BT compared to RP (P<0.001).The single-center data analysis showed no significant difference between BT and RP in the 5-year bPFS (P=0.263) and CSS (P=0.946). 【Conclusion】 For patients with high-risk prostate cancer, there is a significant difference in the prognosis of the two treatments if there is no adjustment of age, marital status, TNM stage and other factors, and the efficacy of RP is better than that of BT, especially in patients with survival more than 10 years.However, there is no statistically significant difference in the prognosis after the possible confounding factors are adjusted.Therefore, the initial treatment choice for these patients should be weighed from multiple perspectives, and patients’ choices must be respected after they are fully informed.

[Objective] To explore the effectiveness of scrotal rapid rehabilitation bandage (scrotal girdle) in preventing postoperative complications of varicocele. [Methods] A total of 80 patients with varicocele who underwent microscopical varicocele ligation during Dec.2021 and May 2023 were divided into the experimental group (n=40) and control group (n=40) by the random number table method.All patients received wound dressing one week after surgery and stopped using it after wound healing.Additionally, the experimental group was treated with scrotal girdle for another 8 weeks.The preoperative and postoperative scores of scrotal edema on the 2nd, 4th and 6th day after surgery, satisfaction, length of hospital stay, frequency of dressing changes, pain intensity, complications, serum testosterone level and semen routine at the 12th week after surgery were compared between the two groups. [Results] The score of scrotal edema in the experimental group was (1.12±0.38) on the 6th day after operation, which was significantly lower than that in the control group (1.68±0.50) (P<0.05). The hospitalization time of the experimental group was significantly shorter than that of the control group, and the frequency of dressing changes was also significantly reduced, with statistical significance (P<0.05). The patient satisfaction was 95% in the experimental group higher than 80% in the control group (P<0.05). The sperm density was (54.12±6.23) ×10⁶/L and the sperm motility rate was (66.45±0.44)% in the experimental group, while the sperm density was (41.53±8.51) ×10⁶/L and the sperm motility rate was (57.85±0.47)% in the control group.The sperm density, sperm motility rate, and sperm malformation rate of both groups were significantly improved after surgery, and the sperm density and sperm motility rate of the experimental group improved more significantly than those of the control group, with statistical significance (P<0.05). [Conclusion] The scrotal rapid rehabilitation bandage is more advantageous than traditional external bandaging materials for patients with varicocele after operation, which can accelerate the postoperative rehabilitation of patients and has more clinical practicability.

In recent years, minimally invasive surgery has been rapidly developed and has become the first choice for the treatment of moderate to severe benign prostatic hyperplasia (BPH). Although it can significantly improve the lower urinary tract symptoms, reduce complications, and enhance security, postoperative sexual dysfunction(SD) is still common, which affects the patients’ quality of life. In this paper, we discuss the incidence rate of SD after BPH surgery, the protection strategy of sexual function, and how to choose reasonable treatment from the perspective of sexual function protection.

【Objective】 To explore the clinical efficacy and safety of pelvic floor magnetic and electrical stimulation combined with Kegel exercise training in the treatment of stress urinary incontinence (SUI) after minimally invasive surgery for benign prostatic hyperplasia (BPH). 【Methods】 A total of 52 patients with SUI after minimally invasive surgery for BPH treated during Jan.2016 and Feb.2022 were randomly divided into test group (n=26) and control group (n=26). The test group received pelvic floor magnetic and electrical stimulation and Kegel exercise training, while the control group received Kegel exercise training only. The treatment lasted for 3 months. The scores of International Consultation on Incontinence Modular Questionnaire Short Form (ICIQ-SF), 1 h pad test, International Prostate Symptom Score (IPSS) and Incontinence Quality of Life Questionnaire (I-QoL) were recorded and compared between the two groups before and after treatment. The adverse reactions were observed. 【Results】 The scores of ICIQ-SF, IPSS and I-QoL and 1 h pad test significantly decreased in both groups after treatment (P<0.05). Before treatment, there were no significant differences of the above indicators between the two groups (P>0.05), but after treatment, the scores of ICIQ-SF,IPSS,I-QoL and 1 h pad test were significantly lower in the test group than in the control group (P<0.05). No severe adverse reactions were observed. 【Conclusion】 Pelvic floor magnetic stimulation combined with Kegel exercise training is safe and effective for SUI after minimally invasive surgery for BPH.

【Objective】 To compare the efficacy and safety of thulium laser enucleation of the prostate (ThULEP) and holmium laser enucleation of the prostate (HoLEP) in the treatment of benign prostatic hyperplasia (BPH). 【Methods】 Randomized controlled trials (RCTs) and clinical controlled trials (CCTs) were searched in PubMed, Embase, Cochrane Library, CNKI and Wanfang Database from Jan.1,2010 to May 30,2022. Two reviewers independently screened literature, extracted data, and assessed the risk of bias of included studies. All divergences were resolved by a third researcher. RevMan 5.4 software was used for Meta analysis. 【Results】 A total of 7 studies were included, involving 1 726 patients, 750 in the ThULEP group and 976 in the HoLEP group. Meta analysis showed that, compared with HoLEP group, the ThULEP group had shorter catheter indwelling time [MD=-0.10, 95%CI (-0.17--0.03), P=0.004] , shorter hospital stay [MD=-0.43, 95%CI (-0.60--0.25), P<0.000 01] , lower IPSS score 12 months after surgery [MD=-1.13, 95%CI (-1.95- -0.30), P=0.007] , lower QoL score 12 months after surgery [MD=-1.00, 95%CI (-1.19- -0.81), P<0.001] ,lower transfusion rate [OR=0.11, 95%CI (0.03-0.36), P=0.000 3] and lower incidence of urinary incontinence [OR=0.24, 95%CI (0.09-0.66), P=0.006] . 【Conclusion】 ThULEP may have similar efficacy and safety as HoLEP in the treatment of BPH, and has more advantages in some aspects.
