IntroductionIt has been shown that endoscopic enucleation of the prostate (EEP) allows for similar efficacy and safety, no matter what energy and type of instruments we use, but the length of learning may differ greatly. The aim of this systematic review is to verify if there is any significant difference between EEP methods in learning.Evidence acquisitionWe performed a systematic literature search in three databases and included only the articles containing their own data on the EEP learning curve assessment during the last 10 years. The primary endpoint was to determine the necessary experience needed to achieve a plateau. The secondary endpoints were to review methods used to evaluate a learning curve.Evidence synthesisThe final sample included 17 articles, containing a total of 4615 EEPs performed by 76 surgeons, the most common method was HoLEP (9/17). The majority of articles studying HoLEP report a learning curve of experience level achievement in roughly 30–40 (min 20; max 60) cases. The studies of GreenLight laser showed high heterogeneity in the results with minimum of 20 cases and maximum of 150–200 cases. TUEB required roughly 40–50 cases to reach the plateau.ConclusionAlthough EEP is considered challenging, it shows a steep learning curve with a plateau after 30–50 cases. Proper criteria are critical for accurate assessment of the learning curve. The Trifecta and Pentafecta criteria are currently the most appropriate method to evaluate EEP learning.

Purpose The solid-state Thulium laser (Tm: YAG) is a novel alternative to the widely used Holmium laser for endoscopic enucleation of the prostate (EEP) due to its relatively high peak power. The aim of this study was to examine the efficacy and safety of a new pulsed Tm: YAG laser in its first application in humans. Methods Data were retrospectively collected for the first 103 patients who underwent EEP with a new pulsed solid-state Tm: YAG laser (Thulio ® , Dornier MedTech Systems GmbH, Weßling, Germany). Peri- and postoperative data were assessed. Procedure-specific complications were graded using Clavien-Dindo Classifications (CDC). Patients were interviewed 15 months after the surgery to evaluate functional and long-term outcomes. Statistical analysis was performed with Statistical Package for the Social Sciences (SPSS ® ). Results The mean preoperative prostate volume was 105.6 ± 55.0 ml. Median enucleation speed was 4.1 g per minute (range 1.1–9.7). Short-term postoperative complications occurred in 21 patients (20.4%), but no high-grade complications (CDC ≥ IV) were observed. Five patients suffered gross haematuria and required reintervention (CDC IIIb; 4.9%). After 15 months, 76 patients (73.8%) participated in the follow-up interview, where seven patients (9.2%) reported complications, including two reinterventions for urethral strictures (CDC IIIb; 2.6%). Most patients reported an improvement in continence (54.0%) and urine stream (93.4%), but no difference in erectile function (81.6%). No persistent dysuria was reported. Patient satisfaction with the surgery results was very high (96.1%). Conclusion Endoscopic enucleation of the prostate with the new pulsed solid-state Tm: YAG laser is a safe and effective option for surgical BPH treatment.

To investigate the association of demographic, clinical and psychosocial variables with levels of anxiety and depression in participants wearing an ocular prosthesis after eye enucleation. This cross-sectional study included 195 participants with an enucleated eye who were attending an ophthalmic clinic for prosthetic rehabilitation between July and November 2014. Demographic and clinical data, and self-reported feelings of shame, sadness and anger were collected. Participants also completed the National Eye Institute Visual Function Questionnaire, the Facial Appearance subscale of the Negative Physical Self Scale, and the Hospital Anxiety and Depression Scale. Regression models were used to identify the factors associated with anxiety and depression. The proportion of participants with clinical anxiety was 11.8% and clinical depression 13.8%. More anxiety and depression were associated with poorer vision-related quality of life and greater levels of appearance concerns. Younger age was related to greater levels of anxiety. Less educated participants and those feeling more angry about losing an eye are more prone to experience depression. Clinical variables were unrelated to anxiety or depression. Anxiety and depression are more prevalent in eye-enucleated patients than the general population, which brings up the issues of psychiatric support in these patients. Psychosocial rather than clinical characteristics were associated with anxiety and depression. Longitudinal studies need to be conducted to further elucidate the direction of causality before interventions to improve mood states are developed.

Retinoblastoma management remains complex, requiring individualized treatment based on International Classification of Retinoblastoma (ICRB) staging, germline mutation status, family psychosocial factors and cultural beliefs, and available institutional resources. For this 2020 retinoblastoma review, PubMed was searched for articles dated as early as 1931, with an emphasis on articles from 1990 to the present day, using keywords of retinoblastoma, chemotherapy, intravenous chemotherapy, chemoreduction, intra-arterial chemotherapy, ophthalmic artery chemosurgery, intravitreal chemotherapy, intracameral chemotherapy, cryotherapy, transpupillary thermotherapy, laser, radiation, external beam radiotherapy, plaque radiotherapy, brachytherapy, and enucleation. We discuss current treatment modalities as used in the year 2020, including intravenous chemotherapy (IVC), intra-arterial chemotherapy (IAC), intravitreal chemotherapy (IvitC), intracameral chemotherapy (IcamC), consolidation therapies (cryotherapy and transpupillary thermotherapy [TTT]), radiation-based therapies (external beam radiotherapy [EBRT] and plaque radiotherapy), and enucleation. Additionally, we present a consensus treatment algorithm based on the agreement of three North American retinoblastoma treatment centers, and encourage further collaboration amongst the world's most expert retinoblastoma treatment centers in order to develop consensus management plans and continue advancement in the identification and treatment of this childhood cancer.

Enucleation and exenteration are widely utilized ophthalmic procedures in veterinary field. Enucleation in camels is like other large animals, typically performed under the influence of heavy sedation and loco-regional analgesia. The aim of the current study was to introduce a new surgical approach to enucleate the eye of camels through supraorbital fossa approach. for that purpose, the technique was applied to seven camels referred to the King-fisal teaching veterinary hospital for unilateral enucleation. Assessment of applicability, safety and feasibility of this technique was done. All procedures were performed in the kush (sitting) position under the influence of heavy sedation with Xylazine HCl in combination with retrobulbar nerve block. A \"C\" shaped skin incision was made in the skin and fascia of the supraorbital fossa to enter the orbital cavity, after which the periorbital fat was gripped, dissected and removed. Bleeding controlled by electrocautery and visible large blood vessels were ligated. After ligation the optic nerve and ophthalmic blood vessels, the eyeball was dissected sharply and freed from the orbital bony attachment. Finally, the orbital fascia and skin were sutured with simple interrupted pattern separately. The approach proved successful in all camels, with the enucleation procedure being both feasible and easily performed. The mean surgical time was approximately 46.6±12.4 minutes. The minimal occurrence of short and long-term complications was encouraging, and the cosmetic outcomes were notably improved. The supraorbital approach is a safe and effective technique for camel ophthalmic surgery, showing advantages in exposure and minimal complications. Further research is needed for validation and broader clinical applications.

Retinoblastoma (Rb) is the most common primary intraocular malignancy of childhood, but an uncommon paediatric cancer, with a constant incidence worldwide of 1:15,000–1:20,000 live births. Despite its rarity, Rb has served as a cornerstone in the field of oncology in many of the aspects that comprise cancer management, including classification schemes, treatment modalities, genetic testing and screening. Until just over half a century ago, the major treatment for Rb was eye removal, and prognosis was poor with outcome fatal for most children. The dramatic evolution, in a short period of time across all fields of Rb management, as well as the development of specialized centres, better infrastructure and introduction of awareness campaigns, has resulted in nearly 100% survival in developed countries and allowed eye salvage in many of the cases. External beam radiotherapy was used as the main treatment choice for four decades, but replaced by chemotherapy at the turn of the century. Initially, and still in many centres, chemotherapy is administered intravenously, but recently is targeted directly into the eye by means of intra-ophthalmic artery and intravitreal chemotherapy. To date, a range of treatments is available to the Rb expert, including enucleation, but there is lack of consensus in a number of scenarios as to what to use and when. In such a rare cancer, treatment outcomes are reported usually via retrospective analyses, with few prospective randomized controlled trials. Classification schemes have also evolved following the introduction of new treatment modalities, but discrepancies exist among centres with respect to the preferred schema and its interpretation. Retinoblastoma management is a remarkable success story, but the future will require a collaborative effort in the form of multicentre randomized controlled trials in order to further improve the quality of care for this subset of young children with ocular cancer.

Purpose Endoscopic enucleation of the prostate (EEP) is a preferred treatment for benign prostatic hyperplasia (BPH). This bibliometric analysis aims to analyze the application trends and research hotspots of EEP. Methods We conducted a bibliometric analysis of publications indexed in the Web of Science Core Collection from 1989 to 2023. The techniques examined include holmium laser enucleation (HoLEP), thulium laser enucleation (ThuLEP/ThuFLEP), bipolar/monopolar transurethral enucleation (b-TUEP/m-TUEP), GreenLight laser enucleation (GreenLEP), and diode laser enucleation (DiLEP). We utilized VOSviewer, CiteSpace, and the R package ‘bibliometrix’ for the analysis. Results A total of 739 English-language studies were analyzed, revealing a steady increase in EEP-related publications. HoLEP was the most extensively studied technique, followed by ThuLEP and b-TUEP, while ThuFLEP gaining emerging interest. There has been a notable lack of high-quality randomized controlled trials (RCTs) for GreenLEP, DiLEP and m-TUEP. China, the United States, and Germany led in publication volume and collaboration networks. Key contributors in the field were identified, with recent research focusing on topics like postoperative transient urinary incontinence (TUI) and the role of robot-assisted simple prostatectomy (RASP) in comparison to EEP. Conclusions EEP is gaining widespread clinical acceptance for BPH treatment. Future research should focus on addressing the gap in high-quality RCTs, especially for underexplored techniques like GreenLEP, DiLEP and m-TUEP, and explore strategies to reduce postoperative TUI. Prospective comparisons between RASP and EEP will be crucial for optimizing surgical approaches in BPH management.

PurposeHoLEP represents an excellent treatment option for benign prostatic hyperplasia. Recently, ‘en bloc’ techniques resulting in improved visualization, shorter surgical times, and easier recognition of the dissection plane have been described. In this paper we describe the ‘En bloc’ HoLEP technique with early apical release.Materials and methodsBetween January 2015 and March 2017, 137 consecutive patients were subjected to this technique by a single surgeon. The following parameters were measured pre- and post-procedure: International Prostate Symptom Score (IPSS), maximum flow rate (Qmax), post-void residual urine (PVR) and PSA. Complications were recorded.ResultsMean (SD; range) age was 66 years (8.0; 51–84), mean PSA was 4.8 ng/ml (7.0; 0.3–70), mean prostate volume was 75.63 ml (42.1; 37–253), mean volume of prostatic tissue removed was 65.9 ml (35.8; 30–217). Mean surgical duration was 47.58 min (21.3; 15–120 min): enucleation 31.5 min (14.9; 5–80 min), morcellating 6.9 min (6.6; 1–60 min). Mean hospitalization duration was 1.2 days (range 1–3), mean catheterization time was 1.2 days (range 1–5). The rate of stress urinary incontinence (SUI) was 5.8, 1.5 and 0.7% at 1, 3, and 6 months post-operation, respectively. Compared to pre-operative values, IPSS, Qmax, and PVR showed significant improvements at 1, 3, 6, and 12 months following the operation (p < 0.05).Conclusions‘En Bloc’ HoLEP with early apical release is a safe technique that allows for easier recognition of the surgical plane and preserves the external sphincter’s mucosa to provide low rates of post-operative stress incontinence and significant functional results.

ObjectiveTo compare open simple prostatectomy, endoscopic enucleation and laparoscopic, robot-assisted enucleation of high-volume prostate in terms of operation time, blood loss, transfusion and complication rates and early continence rates.Material and methodsPatients with BPH treated endoscopically (ThuVEP, Hamburg and Hannover) or robotically (Mainz) were evaluated prospectively for prostate size, free flow and validated questionnaires (IPSS, QoL). 35 patients were matched to patients after open prostatectomy (Mainz) for age, prostate size, IPSS and QoL scores. Operation time was noted from the first cut to the last suture; blood loss was estimated by the drop of haemoglobin preoperatively and one day after surgery. Transfusion rates were documented. Early continence was estimated by pad use over the first 24 h after catheter removal. Statistical analysis was performed with SPSS 22.0.ResultsNo significant differences in prostate size, age and preoperative questionnaires were found (p > 0.3). Postoperative flow and the results of the questionnaires were significantly improved (all p < 0.05), without difference between the approaches (p > 0.8). Endoscopic surgery showed superiority in operation time (both p < 0.05); blood loss and transfusion rates were significantly lower compared to open surgery (both p < 0.01) and lower than in robotic surgery without reaching significance (p = 0.18, p = 0.36). Similar results were seen in early continence rates.ConclusionDue to our results, endoscopic surgery should be considered as first-line therapy unless there are comorbidities like diverticula and/or bladder calculi that can be easily treated simultaneously by robotic surgery. Against the background of these findings, indications favouring open surgery are getting sparse.
