Background: Male stress urinary incontinence (SUI) after surgical treatment of benign prostatic enlargement (BPE) is an infrequent but dreadful complication and constitutes a therapeutic challenge. The efficacy and safety of the adjustable trans-obturator male system (ATOMS®) in these patients is rather unknown, mainly due to the rarity of this condition. We aimed to assess the results of ATOMS to treat SUI after transurethral resection (TURP) or holmium laser enucleation (HoLEP) of the prostate. Methods: Retrospective multicenter study evaluating patients with SUI after TURP or HoLEP for BPE primarily treated with silicone-covered scrotal port (SSP) ATOMS implants in ten different institutions in Europe and Canada between 2018 and 2022. Inclusion criteria were pure SUI for >1 year after endoscopic treatment for BPE and informed consent to receive an ATOMS. The primary endpoint of the study was a dry rate (pad test ≤ 20 mL/day after adjustment). The secondary endpoints were: the total continence rate (no pads and no leakage), complication rate (Clavien-Dindo classification) and self-perceived satisfaction (Patient Global Impression of Improvement (PGI-I) scale 1 to 3). Descriptive analytics, Wilcoxon\'s rank sum test and Fisher\'s exact test were performed. Results: A total of 40 consecutive patients fulfilled the inclusion criteria, 23 following TURP and 17 HoLEP. After ATOMS adjustment, 32 (80%) patients were dry (78.3% TURP and 82.4% HoLEP; p = 1) and total continence was achieved in 18 (45%) patients (43.5% TURP and 47% HoLEP; p = 0.82). The median pad test was at a 500 (IQR 300) mL baseline (648 (IQR 650) TURP and 500 (IQR 340) HoLEP; p = 0.62) and 20 (IQR 89) mL (40 (IQR 90) RTUP and 10 (IQR 89) HoLEP; p = 0.56) after adjustment. Satisfaction (PGI-I ≤ 3) was reported in 37 (92.5%) patients (95.6% TURP and 88.2% HoLEP; p = 0.5). There were no significant differences between patients treated with TURP or HoLEP regarding the patient age, radiotherapy and number of adjustments needed. After 32.5 (IQR 30.5) months, median follow-up postoperative complications occurred in seven (17.5%) cases (two grade I and five grade II; three after TURP and four HoLEP) and two devices were removed (5%, both HoLEP). Conclusions: ATOMS is an efficacious and safe alternative to treat SUI due to sphincteric damage produced by endoscopic surgery for BPE, both TURP and HoLEP. Future studies with a larger number of patients may identify predictive factors that would allow better patient selection for ATOMS in this scenario.

BACKGROUND: Transurethral holmium laser enucleation of the prostate (HoLEP) has a good therapeutic effect on benign prostatic hyperplasia (BPH). The purpose of this study was to investigate the clinical efficacy of HoLEP in the treatment of high-risk elderly patients with BPH and assess its impact on the inflammatory response, vascular endothelial function and quality of life (QoL).
METHODS: Patients at high risk of BPH who were hospitalised in Chengde Central Hospital from February 2021 to December 2022 were retrospectively selected as the study objects, and a total of 100 cases were included. The control group underwent transurethral resection of the prostate, and the observation group underwent HoLEP. Perioperative indexes, urodynamic indexes, QoL 6 months after surgery and incidence of postoperative complications were compared between the two groups. Moreover, serum levels of inflammatory factors and vascular endothelial factors were detected in two groups.
RESULTS: We found no significant difference in general data between the two groups of patients (p > 0.05). The operation time, perioperative bleeding, bladder flushing time and hospitalisation time of the observation group were significantly shorter than those of the control group (p < 0.05). On the 7th day after surgery, the serum levels of tumour necrosis factor alpha, interleukin-1β, interleukin-6, vascular endothelial growth factor, basic fibroblast growth factor and endothelin-1 in the observation group were significantly lower than those in the control group (p < 0.05). Six months after surgery, the maximal urinary flow rate and QoL scores of the patients in the observation group were significantly higher than those of the control group (p < 0.05), and the residual urine volume and International Prostate Symptom Score of observation group were significantly lower than those of the control group (p < 0.05). The incidence of postoperative complications in the observation group was significantly lower than that in the control group (χ2 = 7.440, p = 0.006).
CONCLUSIONS: HoLEP can effectively remove hyperplasia of the prostate and reduce the inflammatory response in the patient\'s body when treating BPH in high-risk elderly patients. It can also regulate the levels of vascular endothelial factors and effectively improve the patient\'s QoL.

Acquired urethral diverticula (UD) in males is an uncommon entity, and it is rarely reported after an open simple prostatectomy or transurethral resection of the prostate. Here, we report a unique case of a UD presenting after holmium laser enucleation of the prostate (HoLEP) in a 69-year-old male with a prostate of 372 g who had five episodes of urine retention over one year despite combined medical treatment with tamsulosin 0.8 mg and finasteride 5 mg. The patient also has elevated prostate-specific antigen (PSA) with five negative prostate biopsies over the last few years. The procedure lasted six hours with difficult morcellation due to beach balls that took 3.5 hours. There were no intraoperative complications. However, he continued to have mixed urine incontinence and recurrent (six) episodes of urinary tract infection (UTI) in the first postoperative year. On evaluation, his urodynamic study did not reproduce stress urinary incontinence (SUI); however, cystoscopy and retrograde urethrogram diagnosed a 6-cm UD in the bulbar penile urethra with penoscrotal mass. The patient underwent urethral diverticulectomy and urethroplasty with a buccal mucosa graft to correct the defect. Six months after his urethral reconstruction, he continued to have mixed urine incontinence needing two pads/day. Although male UD is a rare condition, our case report seeks to heighten awareness of such a potential rare complication in men with recurrent UTIs and refractory urinary incontinence after prolonged HoLEP for extremely large prostates.

Transurethral resection of the prostate (TURP) is the gold-standard classical method for the treatment of benign prostatic hyperplasia (BPH). In minimally invasive surgery, holmium laser enucleation of the prostate (HoLEP) is considered an alternative option. In this systematic review and meta-analysis, we aimed to comprehensively evaluate the advantages and disadvantages of TURP and HoLEP the treating BPH. We comprehensively searched PubMed, Cochrane Library, EMBASE, and Web of Science databases for all randomized controlled trials published before 1 December 2022 comparing HoLEP and TURP. The study protocol is registered on INPLASY (DOI: 10.37766/inplasy2023.5.0065). Compared with TURP, HoLEP required longer operation time but shorter catheter duration, hospital stay, and bladder irrigation time, as well as less postoperative irrigation. With HoLEP, maximum urinary flow rate at 12 and 24 months after surgery; post-void residual volume at 1, 6, and 12 months; and International Prostate Symptom Score at 12 months after surgery were superior to those with TURP. HoLEP was associated with significantly lower risk of hyponatremia, blood transfusion, and urethral stricture but greater risk of postoperative dysuria. Compared with TURP, HoLEP had better curative efficacy at 6, 12, and 24 months after operation and lower incidence of adverse events in patients with BPH.

Introduction and Objectives: Robot-assisted simple prostatectomy (RASP) and holmium laser enucleation of the prostate (HoLEP) are both well-established, minimally invasive surgical treatment options for lower urinary tract symptoms caused by benign prostatic enlargement. We have reported the first comparative analysis of both techniques in patients with prostates of ≥200 cc. Materials and Methods: Between 2009 and 2020 a total of 53 patients with a prostate volume of ≥200 cc were surgically treated at OLV Hospital Aalst (Belgium): 31 underwent RASP and 22 underwent HoLEP. Preoperative and postoperative assessments included uroflowmetry with maximum urinary flow rate (Qmax) and postvoid residual volume (PVR), as well as the International Prostate Symptom Score (IPSS) and quality of life (IPSS-QoL). The complication rates were evaluated according to the Clavien-Dindo Classification. Results: Patients treated with RASP had significantly larger prostate volumes compared with HoLEP (median 226 cc vs 204.5 cc, p = 0.004). After a median follow-up of 14 months, both groups showed a significant improvement in the maximum flow rate (+10.60 mL/s vs +10.70 mL/s, p = 0.724) and a reduction of the IPSS score (-12.50 vs -9, p = 0.246) as well as improvement of the QoL (-3 vs -3, p = 0.880). Median operative time was similar in both groups (150 minutes vs 132.5 minutes, p = 0.665). The amount of resected tissue was lower in the RASP group (134.5 g vs 180 g, p = 0.029) and there was no significant difference in postoperative prostate-specific antigen (1.2 ng/mL vs 0.8 ng/mL, p = 0.112). Despite a similar median catheterization time (3 days vs 2 days, p = 0.748), the median hospitalization time was shorter in the HoLEP group (4 days vs 3 days, p = 0.052). Complication rates were similar in both groups (32% vs 36%, p = 0.987). Conclusion: Our results suggest similar outcomes for RASP and HoLEP in patients with very large prostates ≥200 cc. These findings will require external validation at other high-volume centers.

We performed a systematic review and meta-analysis on efficacy and safety of holmium laser enucleation of prostate compared with bipolar technologies in treating benign prostatic hyperplasia. We analyzed several databases such PubMed, Embase, and Web of Science. Two reviewers independently reviewed studies for consistent criteria and extracted relevant data. Reviewers independently assessed the risk of bias and strength of the evidence for the body of the literature. Ten randomized controlled trials including 1,157 participants were included in this meta-analysis. The holmium laser group had favorable perioperative outcomes in this study. The holmium laser group identified shorter catheterization duration and shorter hospital stay duration than the bipolar technologies group. Efficiency outcomes, such as International Prostate Symptom Score, peak urinary flow rate, quality of life, postvoid residual urine volume, and international index of erectile function reported no obvious differences between the holmium laser and bipolar technologies groups at the 6 to 12 months follow-up. Bipolar technologies and holmium laser groups shared equivalent effectiveness and safety in treatments for benign prostate hyperplasia. Holmium lasers identified lower catheter times, shorter hospital stays, and lesser risk of hemorrhage than bipolar technologies.

UNASSIGNED: To prospectively evaluate safety and efficacy of holmium laser enucleation of prostate (HoLEP) for surgical treatment of recurrent symptoms due to prostatomegaly after prior transurethral resection of prostate (TURP).
UNASSIGNED: We prospectively evaluated 43 patients with a history of TURP who underwent HoLEP (study group). Patients in chronological order who underwent HoLEP without prior TURP were included in the control group. We hypothesized that prior TURP would increase technical difficulties, thereby leading to a reduction in procedure efficiency by 25%. Patients\' demographic, intraoperative, and postoperative data were compared, and statistical analysis was performed.
UNASSIGNED: Demographic data in both groups were comparable. The average interval between past TURP and HoLEP was 4.22 years. There was no difficulty in identifying the dissection plane in the study group and the difference in the procedure efficiency between the study and the control groups were statistically insignificant (0.75 ± 0.31 g/min-study group vs. 0.69 ± 0.36 g/min-control group; P = 0.665). The intraoperative parameters and postoperative outcomes were comparable in both groups.
UNASSIGNED: Prior TURP does not negatively impact the outcome of HoLEP in treating symptomatic recurrence for enlarged prostate after initial TURP.

The aim of this study is to investigate the incidental prostate cancer (iPCa) detection rates of different embedding methods in a large, contemporary cohort of patients with bladder outlet obstruction (BOO) treated with transurethral surgery. We relied on an institutional tertiary-care database to identify BOO patients who underwent either transurethral loop resection or laser (Holmium:yttrium-aluminium garnet) enucleation of the prostate (HoLEP) between 01/2012 and 12/2019. Embedding methods differed with regard to the extent of the additional prostate tissue submitted following the first ten cassettes of primary embedding (cohort A: one [additional] cassette/10 g residual tissue vs. cohort B: complete embedding of the residual tissue). Detection rates of iPCa among the different embedding methods were compared. Subsequently, subgroup analyses by embedding protocol were repeated in HoLEP-treated patients only. In the overall cohort, the iPCa detection rate was 11% (46/420). In cohort A (n = 299), tissue embedding resulted in a median of 8 cassettes/patient (range 1-38) vs. a median of 15 (range 2-74) in cohort B (n = 121) (p < .001). The iPCa detection rate was 8% (23/299) and 19% (23/121) in cohort A vs. cohort B, respectively (p < .001). Virtual reduction of the number of tissue cassettes to ten cassettes resulted in a iPCa detection rate of 96% in both cohorts, missing one stage T1a/ISUP grade 1 carcinoma. Increasing the number of cassettes by two and eight cassettes, respectively, resulted in a detection rate of 100% in both cohorts without revealing high-grade carcinomas. Subgroup analyses in HoLEP patients confirmed these findings, demonstrated by a 100 vs. 96% iPCa detection rate following examination of the first ten cassettes, missing one case of T1a/ISUP 1. Examination of 8 additional cassettes resulted in a 100% detection rate. The extent of embedding of material obtained from transurethral prostate resection correlates with the iPCa detection rate. However, the submission of 10 cassettes appears to be a reasonable threshold to reduce resource utilization while maintaining secure cancer detection.

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.

The purpose of this study was to promote the holmium laser enucleation of the prostate (HoLEP) technology for large-volume prostates (>80 ml) and compare it with the traditional method, we modified the technique and applied this technology to clinical practice. A retrospective study comprising 118 patients who underwent HoLEP surgery from February 2018 to December 2019 was conducted in our center. Group A consisted of 57 patients with large-volume prostate (>80 ml) who received modified \"fenestration and tunnel method\" from February 2019 till December 2019, while group B consisted of 61 patients who received the traditional trivalvular operation method from February 2018 to December 2018 for comparison. Control subjects are selected such that they match the cases concerning certain characteristics, and perioperative data, voiding outcomes, and complications were evaluated at 1- and 12-month follow-up. The international prostatic symptomatic score (IPSS), quality of life (QoL), and maximum flow rate (Qmax) at 1 month and 12 months were both significantly improved compared with the preoperative baseline, and no significant differences were found between Groups A and B. The mean enucleation time, operation time, catheter indwelling duration, and hemoglobin decrease during the operation of Group A showed superiority compared with Group B (p<.05). The modified \"fenestration and tunnel method\" of HoLEP was statistically superior to the traditional trivalvular method in terms of the operation time, enucleation time, catheter indwelling duration, and hemoglobin decrease. For large-volume prostates (>80 ml), modified HoLEP was suggested to be a better treatment option.
