Purpose To compare clinical and urodynamic results of transurethral resection of the prostate (TURP) to original and PErFecTED prostate artery embolization (PAE) methods for benign prostatic hyperplasia. Methods We prospectively randomized 30 patients to receive TURP or original PAE (oPAE) and compared them to a cohort of patients treated by PErFecTED PAE, with a minimum of 1-year follow-up. Patients were assessed for urodynamic parameters, prostate volume, international prostate symptom score (IPSS), and quality of life (QoL). Results All groups were comparable for all pre-treatment parameters except bladder contractility and peak urine flow rate ( Q max ), both of which were significantly better in the TURP group, and IIEF score, which was significantly higher among PErFecTED PAE patients than TURP patients. All groups experienced significant improvement in IPSS, QoL, prostate volume, and Q max . TURP and PErFecTED PAE both resulted in significantly lower IPSS than oPAE but were not significantly different from one another. TURP resulted in significantly higher Q max and significantly smaller prostate volume than either original or PErFecTED PAE but required spinal anesthesia and hospitalization. Two patients in the oPAE group with hypocontractile bladders experienced recurrence of symptoms and were treated with TURP. In the TURP group, urinary incontinence occurred in 4/15 patients (26.7 %), rupture of the prostatic capsule in 1/15 (6.7 %), retrograde ejaculation in all patients (100 %), and one patient was readmitted for temporary bladder irrigation due to hematuria. Conclusions TURP and PAE are both safe and effective treatments. TURP and PErFecTED PAE yield similar symptom improvement, but TURP is associated with both better urodynamic results and more adverse events.

Purpose To evaluate the safety and efficacy of transurethral holmium laser enucleation of the prostate (HoLEP) compared to bipolar transurethral resection of the prostate (bTUR-P) in the treatment of benign prostatic hyperplasia (BPH). Methods A total of 220 BPH patients hospitalized from January 2022 to September 2023 were included in this study. These patients were randomly assigned to HoLEP and bTUR-P groups, with 110 participants in each group. We collected preoperative general information, perioperative data, complications, and postoperative follow-up indicators from both groups of patients. Results The baseline characteristics of patients in both groups were similar, with no statistical significance ( P  > 0.05). Compared to the bTUR-P group, the HoLEP group exhibited significantly less intraoperative bleeding ( P  < 0.001), shorter bladder irrigation time ( P  = 0.002), shorter catheter retention time ( P  < 0.001), and reduced postoperative hospitalization ( P  = 0.002). Additionally, the pain score during urination after catheter removal was significantly lower in the HoLEP group ( P  < 0.001). Postoperative complications occurred in both groups; however, they were less frequent in the HoLEP group (4 cases), primarily consisting of urinary retention and postoperative bleeding. The bTUR-P group experienced more complications (9 cases). Significant reductions in postoperative residual urine volume (RUV) were observed in both groups ( P  < 0.001). Both groups also showed significant improvements in Quality of Life (QoL) scores and International Prostate Symptom Scores (IPSS), with the HoLEP group demonstrating a more significant decrease in IPSS ( P  < 0.001). Conclusion After comprehensive evaluation, HoLEP was superior to bTUR-P in terms of safety and efficacy. Therefore, HoLEP may be a preferable choice for the treatment of BPH.

Perioperative hypothermia causes postoperative complications. Prewarming reduces body temperature decrease in long-term surgeries. We aimed to assess the effect of different time-periods of prewarming on perioperative temperature in short-term transurethral resection under general anesthesia. Randomized, double-blind, controlled trial in patients scheduled for bladder or prostatic transurethral resection under general anesthesia. Eligible patients were randomly assigned to receive no-prewarming or prewarming during 15, 30, or 45 min using a forced-air blanket in the pre-anesthesia period. Tympanic temperature was used prior to induction of anesthesia and esophageal temperature intraoperatively. Primary outcome was the difference in core temperature among groups from the induction of general anesthesia until the end of surgery. Repeated measures multivariate analysis of covariance modeled the temperature response at each observation time according to prewarming. We examined modeled contrasts between temperature variables in subjects according to prophylaxis. We enrolled 297 patients and randomly assigned 76 patients to control group, 74 patients to 15-min group, 73 patients to 30-min group, and 74 patients to the 45-min group. Temperature in the control group before induction was 36.5 ± 0.5 °C. After prewarming, core temperature was significantly higher in 15- and 30-min groups (36.8 ± 0.5 °C, p = 0.004; 36.7 ± 0.5 °C, p = 0.041, respectively). Body temperature at the end of surgery was significantly lower in the control group (35.8 ± 0.6 °C) than in the three prewarmed groups (36.3 ± 0.6 °C in 15-min, 36.3 ± 0.5 °C in 30-min, and 36.3 ± 0.6 °C in 45-min group) (p < 0.001). Prewarming prior to short-term transurethral resection under general anesthesia reduced the body temperature drop during the perioperative period. These time-periods of prewarming also reduced the rate of postoperative complications. Study Registration Registered at ClinicalTrials.gov (Identifier: NCT03630887).

Purpose We aimed to assess the efficacy and safety of transurethral enucleation with bipolar system (TUEB) regardless of the prostate size using a specially developed TUEB loop. Methods A total of 251 patients who underwent TUEB were categorized into two groups depending on the prostate volume (PV): small-PV (≤ 80 mL) group, 133 patients; large-PV (> 80 mL) group, 118 patients. Comparisons of background information and treatment outcomes were performed between the groups. Results Operation (113.5 vs 166.4 min), enucleation (49.4 vs 68.1 min), and morcellation (11.4 vs 26.4 min) times were longer and hemoglobin decreased significantly (0.84 vs 1.30 g/dL) in the large PV group. However, the enucleation efficiency (enucleated weight per enucleation time; 0.71 vs 0.97 g/min) and prostate-specific antigen reduction rate (24.6% vs 16.1%) were significantly better in the large-PV group, with similar enucleation rates (enucleated weight per transitional zone volume; 82% vs 81%). The International Prostate Symptom Score, uroflowmetry maximum flow rate, and post-void residual urine in both groups improved at 3, 6, and 12 months compared with baseline. No patient underwent blood transfusion. There were no differences in the frequency of postoperative clot retention, urethral stricture, or stress incontinence at 3, 6, and 12 months. Conclusion TUEB using a TUEB loop resulted in high levels of satisfaction regarding the enucleation efficiency, efficacy, and safety for BPH surgery regardless of the prostate size. TUEB should be considered one of the best treatment options for large BPH that is uncontrollable with medication.

Introduction Benign prostatic hyperplasia (BPH) is a common urological condition, particularly among middle-aged and elderly men. Trans urethral resection of prostate (TURP) has some drawbacks, particularly concerning ejaculatory function. Ejaculation preserving TURP (Ep-TURP) is one such technique that aims at preserving the tissues that are primarily responsible for antegrade ejaculation. Methods and material In this prospective study, patients with bothersome LUTS were randomized into Ep-TURP and standard TURP groups. Supramontal tissue was preserved in Ep-TURP while standard TURP group had resection of the entire prostatic tissue up to the verumontanum. The outcomes with regard to IPSS, Qmax, IIEF(Q9), Ejaculation and PVR were studied. Ejaculation projection score was separately calculated and assessed. Results About 60 patients were studied, with 30 in each group. At 6 months’ follow-up, complication rates were the same in both groups. The IPSS, Qmax, IIEF were similar and comparable. There was no change in erection in all patients (P = 0.559). The ejaculation was well preserved in Ep-TURP (p<0.001). Ejaculation projection score was maintained at 3.77 in the Ep-TURP group while in the standard group it was 0 (P<0.001). Conclusions Ep-TURP is a safe and a cost-effective method of preserving ejaculation in patients undergoing TURP. This procedure adds a better quality of life that greatly aids in enhancing the improving his psychological outlook towards life. Ep-TURP has now emerged as the standard procedure of choice in sexually active young males needing TURP, as the degree of ejaculation is largely well preserved in patients undergoing this procedure.

Purpose The purpose of this study was to investigate the efficacy of Transurethral Holmium Laser of the Prostate (HoLEP) with Double-n Technology in the treatment of benign prostatic hyperplasia (BPH), with a focus on preserving sexual function postoperatively. Methods Conducted as a multicenter, prospective, single-blind randomized controlled trial, this study enrolled sexually active male patients with BPH. Participants were randomized into three groups: standard HoLEP (Group A), single-n technology (Group B), and innovative double-n technology (Group C), which emphasizes the preservation of the urethral mucosa and nearby structures. The primary endpoints included maximum urinary flow rate (Qmax), International Prostate Symptom Score (IPSS), and International Index of Erectile Function (IIEF). Results Of the 180 initial participants, 139 completed the study. All groups showed significant improvements in Qmax and IPSS. Initial declines in IIEF scores were noted across all groups, stabilizing to baseline by 3 months without further improvement. Group A had modest antegrade ejaculation rates, starting at 15.4% at 3 months and reaching 23.1% at 12 months. Group B showed a significant improvement, with AE rates rising from 31.8% at 3 months to 45.5% at 12 months, significantly higher than Group A ( p  < 0.05). Group C had the highest AE rates, starting at 57.8% at 3 months and reaching 77.8% at 12 months, significantly surpassing both Group A and B ( p  < 0.05). Regarding semen reduction, Group A had 100% reduction at 3 months, which decreased to 77.8% at 12 months. Group B followed a similar trend, from 100% at 3 months to 68.2% at 12 months. Group C showed a more pronounced decline, starting at 84.6% at 3 months and dropping to 37.1% at 12 months, with values significantly lower than both Groups A and B ( p  < 0.05). Conclusions The double-n HoLEP technique shows promising results in improving urinary symptoms while better preserving ejaculatory function and sexual quality of life in BPH patients. This technique could offer a significant advancement in the surgical management of BPH, particularly for sexually active patients.

PurposeTo quantitatively assess 12-month prostate volume (PV) reduction based on T2-weighted MRI and immediate post-treatment contrast-enhanced MRI non-perfused volume (NPV), and to compare measurements with predictions of acute and delayed ablation volumes based on MR-thermometry (MR-t), in a central radiology review of the Phase I clinical trial of MRI-guided transurethral ultrasound ablation (TULSA) in patients with localized prostate cancer.Materials and methodsTreatment day MRI and 12-month follow-up MRI and biopsy were available for central radiology review in 29 of 30 patients from the published institutional review board-approved, prospective, multi-centre, single-arm Phase I clinical trial of TULSA. Viable PV at 12 months was measured as the remaining PV on T2-weighted MRI, less 12-month NPV, scaled by the fraction of fibrosis in 12-month biopsy cores. Reduction of viable PV was compared to predictions based on the fraction of the prostate covered by the MR-t derived acute thermal ablation volume (ATAV, 55°C isotherm), delayed thermal ablation volume (DTAV, 240 cumulative equivalent minutes at 43°C thermal dose isocontour) and treatment-day NPV. We also report linear and volumetric comparisons between metrics.ResultsAfter TULSA, the median 12-month reduction in viable PV was 88%. DTAV predicted a reduction of 90%. Treatment day NPV predicted only 53% volume reduction, and underestimated ATAV and DTAV by 36% and 51%.ConclusionQuantitative volumetry of the TULSA phase I MR and biopsy data identifies DTAV (240 CEM43 thermal dose boundary) as a useful predictor of viable prostate tissue reduction at 12 months. Immediate post-treatment NPV underestimates tissue ablation.Key Points• MRI-guided transurethral ultrasound ablation (TULSA) achieved an 88% reduction of viable prostate tissue volume at 12 months, in excellent agreement with expectation from thermal dose calculations.• Non-perfused volume on immediate post-treatment contrast-enhanced MRI represents only 64% of the acute thermal ablation volume (ATAV), and reports only 60% (53% instead of 88% achieved) of the reduction in viable prostate tissue volume at 12 months.• MR-thermometry-based predictions of 12-month prostate volume reduction based on 240 cumulative equivalent minute thermal dose volume are in excellent agreement with reduction in viable prostate tissue volume measured on pre- and 12-month post-treatment T2w-MRI.

IntroductionTransurethral resection of the prostate (TURP) is the gold standard surgical treatment to lower urinary tract symptoms and benign prostatic obstruction (LUTS/BPO). Although it has been proven to have substantial efficacy in improving functional outcomes, it has shown a high incidence of complications, including transurethral resection syndrome, massive bleeding, urinary incontinence and sexual dysfunction. High-frequency irreversible electroporation (H-FIRE) is a novel non-thermal ablation technique that delivers pulsed high-voltage but low-energy electric current to the cell membrane, thereby leading to cell death. H-FIRE has been reported to be tissue-selective, which leads to fewer side effects. However, no data are available on whether H-FIRE is non-inferior compared with TURP in treating patients with LUTS/BPO regarding safety and efficacy.Methods and analysisThis trial is a prospective, single-centre, randomised controlled, double-blinded and non-inferiority study in which all men with LUTS/BPO are included. This study aims to determine whether the HI-FIRE is non-inferior to TURP for achieving better functional outcomes as measured by the co-primary outcome of the change from baseline in maximal flow rate (Qmax) and the urinary symptoms by questionnaire of International Prostate Symptom Score (IPSS) scoring at 3 months after surgical treatment. The main inclusion criteria are men with prostatic volume range 30 to 100 mL, Qmax<15 mL/s and IPSS>8. A sample size of 118 participants is required, accounting for a 20% loss. All participants will be randomly allocated at a ratio of 1:1 to the H-FIRE arm (n=59) and the TURP arm (n=59). The primary outcome is to assess the change from baseline in Qmax and IPSS scoring at 3 months after surgical treatment.Ethics and disseminationEthical approval was obtained from the ethics committee of Shanghai East Hospital, Tongji University School of Medicine, Shanghai, China. The results of the study will be disseminated and published in international peer-reviewed journals.Trial registration numberClinicalTrials.gov: NCT05306145.

Purpose To compare the learning curves, perioperative and early functional outcomes after HoLEP and GreenLEP. Methods Data from the first 100 consecutive cases treated by GreenLEP and HoLEP by two surgeons were prospectively collected from dedicated databases and analysed retrospectively. En-bloc GreenLEP and two-lobar HoLEP enucleations were conducted using the GreenLight HPS™ 2090 laser and Lumenis™ holmium laser. Patients’ characteristics, perioperative outcomes and functional outcomes after 1, 3 and 6 months were compared between groups. Results Total energy delivered and operative times were significantly shorter for GreenLEP (58 vs. 110 kJ, p  < 0.0001; 60 vs. 90 min, p  < 0.0001). Operative time reached a plateau after 30 procedures in each group. Length of catheterization and hospital stay were significantly shorter in the HoLEP group (2 vs. 1 day, p  < 0.0001; 2 vs. 1 day, p  < 0.0001). Postoperative complications were comparable between GreenLEP and HoLEP (19 vs. 25 %; p  = 0.13). There was a greater increase of Q max at 3 months and a greater IPSS decrease at 1 month for GreenLEP, whereas decreases in IPSS and IPSS-Q8 at 6 months were greater for HoLEP. Transient stress urinary incontinence was comparable between both groups (6 vs. 9 % at 3 months; p  = 0.42). Pentafecta was achieved in four consecutive patients after the 18th and the 40th procedure in the GreenLEP and HoLEP group, respectively. Learning curves ranged from 14 to 30 cases for GreenLEP and 22 to 40 cases for HoLEP. Conclusion Learning curves of GreenLEP and HoLEP provided roughly similar peri-operative and short-term functional outcomes.

Background Low-intensity shockwave therapy (Li-SWT) can improve bladder function through enhancement of angiogenesis and nerve regeneration and suppression of inflammation and overactivity. In this trial, we aimed to evaluate the efficacy of Li-SWT on persistent storage symptoms after transurethral surgery (TUS) for benign prostatic obstruction (BPO). Methods Between July 2020 and July 2022, 137 patients with persistent storage symptoms; urgency episodes/24 h ≥ 1 and daytime frequency ≥8, for at least three months after TUS for BPO were randomly allocated to Li-SWT versus sham versus solifenacin 10 mg/day in 3:1:1 ratio. The primary end point was the percent reduction from baseline in overactive bladder symptom score (OABSS) at 3-month follow-up. The changes in 3-day voiding diary parameters, quality of life (QoL) score, peak flow rate and residual urine at 3 and 6-month follow-up were compared. Treatment-related adverse effects were also evaluated. Results Baseline data were comparable between groups. The percent reduction from baseline in OABSS at 3-month follow-up was significantly higher in Li-SWT compared to sham (−55% versus −11%), and it was comparable between Li-SWT and solifenacin-10 (−55% versus −60%). Li-SWT achieved significant improvement like solifenacin-10 in 3-day voiding diary parameters and QoL score at 3-month follow-up. This improvement remained comparable between Li-SWT and solifenacin-10 at 6-month follow-up. No adverse effects related to Li-SWT were noted apart from tolerable pain during the procedure. Solifenacin-10 was associated with bothersome adverse effects in 73% of the patients with 11.5% discontinuation rate. Conclusions Li-SWT ameliorates persistent storage symptoms and promotes QoL after TUS for BPO, with comparable efficacy and better tolerance compared to solifenacin.
