RESUMO
PURPOSE: To evaluate Hugo RAS against the Da Vinci system for Robot-Assisted Radical Prostatectomy (RARP) in prostate cancer treatment. METHODS: We compared outcomes of 150 patients with prostate cancer undergoing RARP with either Hugo or Da Vinci systems. Our analysis included operative, postoperative, pathological, and functional outcomes. RESULTS: Both groups had 75 patients. Baseline characteristics and tumor features were similar. Intraoperatively, Da Vinci had a shorter docking time (10.45 vs. 18.62 min, p = 0.02), but total operative times were comparable (145.34 vs 138.95, p = 0.85). Hugo outperformed in neck dissection and lymphadenectomy times (22 vs 13.67 min, p = 0.027 and 37.82 vs 45.77 min, p = 0.025). Postoperative metrics like stay duration, catheter time, and complications showed no significant difference. Functional results, using IPSS and IIEF5, were similar between systems. Six Da Vinci patients (8%) and nine Hugo patients (12%) experienced social incontinence (p = 0.072). Pathological outcomes like T stage, Gleason Score, and nodes removed were alike. However, Hugo had more positive surgical margins (20% vs. 10.67%, p = 0.034). CONCLUSIONS: RARP outcomes using Hugo RAS were similar to the Da Vinci system in our study. More research and extended follow-up are required to ascertain long-term oncological and functional results.

PURPOSE: To compare endoscopic enucleation of the prostate using a thulium: yttrium-aluminum-garnet (Tm:YAG) laser and a super-pulsed thulium fiber laser set in continuous-wave (CW) mode, and to evaluate whether theoretical advantages of thulium fiber lasers, related to their shorter wavelength, translate into relevant clinical differences. METHODS: In total, 110 patients suffering from lower urinary tract symptoms (LUTS) due to benign prostatic hyperplasia were randomized to undergo either thulium:YAG laser enucleation of the prostate (ThuLEP) or CW thulium fiber laser enucleation of the prostate (CW-ThuFLEP). Intraoperative and postoperative variables and complications were compared. Micturition improvement was assessed at 3-month follow-up using the International Prostate Symptom Score (IPSS), post-void residual urine (PVR) and maximum flow rate (Qmax). Erectile function was evaluated using the International Index of Erectile Function-5 (IIEF-5). RESULTS: No significant differences between the ThuLEP and CW-ThuFLEP groups were found in terms of operative time (70.69 vs 72.41 min), enucleation time (50.23 vs 53.33 min), enucleated tissue weight (40.2 vs 41.9 g), enucleation efficiency (0.80 vs 0.79 g/min), catheterization time (2.45 vs 2.57 days), hospital stay (2.82 vs 2.95 days) and hemoglobin drop (1.05 vs 1.27 g/dl). At 3-month follow-up, no significant differences were found in IPSS (5.09 vs 5.81), Qmax (26.51 vs 27.13 ml/s), PVR (25.22 vs 23.81 ml) and IIEF-5 (14.01 vs 14.54). CONCLUSION: ThuLEP and CW-ThuFLEP were equivalent in relieving patients from LUTS and improving micturition. Theoretical advantages of the TFL, such as shallower penetration depth and improved vaporization capacity, did not translate into relevant perioperative outcomes or clinical differences.

PURPOSE: Our objective was to establish a standardized technique for Anatomical Endoscopic Enucleation of Prostate (AEEP) utilizing a consensus statement to provide robust recommendations for urologists who are new to this procedure. METHODS: The participants were electronically sent a questionnaire in three consecutive rounds. In the second and third rounds, the anonymous aggregate results of the previous round were presented. Experts' feedback and comments were then incorporated to refine existing questions or to explore more controversial topics in greater depth. RESULTS: Forty-one urologists participated in the first round. In the second round, all Round 1 participants received a 22-question survey, resulting in a consensus on 21 items. In the third round, 76% (19/25) of the second-round respondents also participated, reaching a consensus on 22 additional items. The panelists consensually agreed on detaching the urethral sphincter at the beginning of the enucleation and not at the end of the enucleation. To prevent incontinence, it was recommended that the apical mucosa be preserved through various approaches between 11 and 1 o'clock while gently disrupting the lateral lobes in their apical part, avoiding an excess energy delivery approximation to the apical mucosa. CONCLUSION: To optimize laser AEEP procedures, urologists must follow expert guidelines on equipment and surgical technique, including early apical release, using the 3-lobe technique for enucleation, preserving apical mucosa with appropriate approaches, gently disrupting lateral lobes at their apical regions, and avoiding excessive energy delivery near the apical mucosa. Following these recommendations can lead to improved outcomes and patient satisfaction.

PURPOSE: To identify expert laser settings for BPH treatment and evaluate the application of preventive measures to reduce complications. METHODS: A survey was conducted after narrative literature research to identify relevant questions regarding laser use for BPH treatment (59 questions). Experts were asked for laser settings during specific clinical scenarios. Settings were compared for the reported laser types, and common settings and preventive measures were identified. RESULTS: Twenty-two experts completed the survey with a mean filling time of 12.9 min. Ho:YAG, Thulium fiber laser (TFL), continuous wave (cw) Tm:YAG, pulsed Tm:YAG and Greenlight™ lasers are used by 73% (16/22), 50% (11/22), 23% (5/22), 13.6% (3/22) and 9.1% (2/22) of experts, respectively. All experts use anatomical enucleation of the prostate (EEP), preferentially in one- or two-lobe technique. Laser settings differ significantly between laser types, with median laser power for apical/main gland EEP of 75/94 W, 60/60 W, 100/100 W, 100/100 W, and 80/80 W for Ho:YAG, TFL, cwTm:YAG, pulsed Tm:YAG and Greenlight™ lasers, respectively (p = 0.02 and p = 0.005). However, power settings within the same laser source are similar. Pulse shapes for main gland EEP significantly differ between lasers with long and pulse shape modified (e.g., Moses, Virtual Basket) modes preferred for Ho:YAG and short pulse modes for TFL (p = 0.031). CONCLUSION: Ho:YAG lasers no longer seem to be the mainstay of EEP. TFL lasers are generally used in pulsed mode though clinical applicability for quasi-continuous settings has recently been demonstrated. One and two-lobe techniques are beneficial regarding operative time and are used by most experts.

PURPOSE OF REVIEW: This study aimed to review recent evidence on conservative non-surgical options for erectile dysfunction (ED) in men. A narrative review of the literature was performed. A comprehensive search in the MEDLINE, Embase, and Cochrane databases was done. Papers in English language, published from May 2017 until May 2022, were included. Papers reporting basic research or animal research were excluded, as long as reviews or meta-analyses. Congress reports, clinical cases, or clinical trials protocols with no results were also excluded. RECENT FINDINGS: We found a multitude of different treatment modalities for ED. We must take into account the type of patient, their comorbidities, the origin of their ED, and its severity in order to reproduce effective results using these therapies. Some of the treatments show good results with a good level of evidence (new IPDE5 formulations, intracavernous injections, shock wave therapy, hormonal theraphy, psycho-sexual theraphy). However, others (some new molecules, stem cell theraphy, platelet-rich plasma injections, oxygenation-based therapy, nutraceuticals), although some of them present promising results, require randomized studies with a larger number of patients and a longer follow-up time to be able to establish firm recommendations. Regarding the conservative treatment of erectile dysfunction, in recent years, some therapies have been consolidated as effective and safe for certain types of patients. On the other hand, other treatment modalities, although promising, still lack the evidence and the necessary follow-up to be recommended in daily practice.

Background and Objectives: We aimed to evaluate the oncological and functional outcomes of organ-sparing surgery for testicular germ cell tumors, a procedure that seeks to strike a balance between effective cancer control and organ preservation, in the treatment of testicular tumors. We aimed to discuss the surgical technique and complications, and determine the appropriate candidate selection for this approach. Material and Methods: A comprehensive literature search was conducted to identify relevant studies on organ-sparing surgery for testicular tumors. Various databases, including PubMed, Embase, and Cochrane Library, were used. Studies reporting on surgical techniques, complications, and oncologic and functional outcomes were included for analysis. Results: Current evidence suggests that organ-sparing surgery for testicular germ cell tumors can be considered a safe and efficacious alternative to radical orchiectomy. The procedure is associated with adequate oncological control, as indicated by low recurrence rates and low complication rates. Endocrine testicular function can be preserved in around 80-90% of patients and paternity can be achieved in approximately half of the patients. Candidate selection for this surgery is typically based on the following criteria: pre-surgery normal levels of testosterone and luteinizing hormone, synchronous or metachronous bilateral tumors, tumor in a solitary testis, and tumor size less than 50% of the testis. Conclusions: Organ-sparing surgery for testicular germ cell tumors offers a promising approach that balances oncological control and preservation of testicular function. Further research, including large-scale prospective studies and long-term follow-ups, is warranted to validate the effectiveness and durability of organ-sparing surgery and to identify optimal patient selection criteria.

BACKGROUND: Stromal interaction molecule (STIM)/Orai calcium entry system appears to have a role in erectile dysfunction (ED) pathophysiology but its specific contribution to diabetic ED was not elucidated. AIM: To evaluate STIM/Orai inhibition on functional alterations associated with diabetic ED in rat and human penile tissues and on in vivo erectile responses in diabetic rats. METHODS: Rat corpus cavernosum (RCC) strips from nondiabetic (No DM) and streptozotocin-induced diabetic (DM) rats and human penile resistance arteries (HPRA) and corpus cavernosum (HCC) from ED patients undergoing penile prosthesis insertion were functionally evaluated in organ chambers and wire myographs. Erectile function in vivo in rats was assessed by intracavernosal pressure (ICP) responses to cavernous nerve electrical stimulation (CNES). Expression of STIM/Orai elements in HCC was determined by immunofluorescence and immunoblot. MAIN OUTCOME MEASURES: Functional responses in RCC, HCC and HPRA and STIM/Orai protein expression in HCC. In vivo erectile responses to CNES. RESULTS: Inhibition of Orai channels with YM-58483 (20 µM) significantly reduced adrenergic contractions in RCC but more effectively in DM. Thromboxane-induced and neurogenic contractions were reduced by STIM/Orai inhibition while defective endothelial, neurogenic and PDE5 inhibitor-induced relaxations were enhanced by YM-58483 (10 µM) in RCC from DM rats. In vivo, YM-58483 caused erections and attenuated diabetes-related impairment of erectile responses. YM-58483 potentiated the effects of PDE5 inhibition. In human tissues, STIM/Orai inhibition depressed adrenergic and thromboxane-induced contractions in ED patients more effectively in those with type 2 diabetes. Diabetes was associated with increased expression of Orai1 and Orai3 in ED patients. CLINICAL TRANSLATION: Targeting STIM/Orai to alleviate diabetes-related functional alterations of penile vascular tissue could improve erectile function and potentiate therapeutic effects of PDE5 inhibitors in diabetic ED. STRENGTHS AND LIMITATIONS: Improving effects of STIM/Orai inhibition on diabetes-related functional impairment was evidenced in vitro and in vivo in an animal model and validated in human tissues from ED patients. Functional findings were complemented with expression results. Main limitation was low numbers of human experiments due to limited human tissue availability. CONCLUSIONS: STIM/Orai inhibition alleviated alterations of functional responses in vitro and improved erectile responses in vivo in diabetic rats, potentiating the effects of PDE5 inhibition. STIM/Orai inhibition was validated as a target to modulate functional alterations of human penile vascular tissue in diabetic ED where Orai1 and Orai3 channels were upregulated. STIM/Orai inhibition could be a potential therapeutic strategy to overcome poor response to conventional ED therapy in diabetic patients. Sevilleja-Ortiz A, El Assar M, García-Gómez B, et al.

PURPOSE: We performed a prospective randomized comparison among Retrograde IntraRenal Surgery (RIRS) and MiniPerc (MP) for stones between 10 and 20 mm to evaluate outcomes with the same laser device: Fiber Dust. METHODS: Patients with a single renal stone between 10 and 20 mm were randomized to RIRS (Group A) versus MP (Group B). Exclusion criteria were age < 18 or > 75, presence of acute infection, coagulation impairments, cardiovascular or pulmonary comorbidities. In both groups, the Fiber Dust laser was used. A CT scan after 3 months was performed. A negative CT scan or asymptomatic patients with stone fragments < 3 mm and a negative urinary culture were the criteria to assess the stone-free status. A statistical analysis was carried out to assess success, complication and retreatment rates and need for auxiliary treatments. RESULTS: Between January 2021 and January 2022, 186 patients were enrolled (90 in Group A and 96 in Group B). Mean stone size was 15.8 mm and 14.9 mm in Group A and B, respectively (p = 0.23). The overall stone-free rate (SFR) was 73.3% for Group A and 84.4% for Group B. A higher SFR was reached for upper calyceal stones in Group A (90.4%) lower calyceal stones in Group B (91.6%). Retreatment rate (p = 0.31) and auxiliary procedure rate (p = 0.18) were comparable. Complication rate was 5.5% and 5.2% for Groups A and B, respectively. CONCLUSIONS: RIRS and MP are both effective to obtain a postoperative SFR with Fiber Dust. According to the stone position one treatment is superior to the other one.

OBJECTIVE: To systematically review the literature in order to investigate the efficacy and safety of surgical and non-invasive penile enhancement procedures for aesthetic and therapeutic purposes. METHODS: A systematic search for papers investigating penile enhancement procedures was performed using the MEDLINE database. Articles published from January 2010 to December 2019, written in English, including >10 cases, and reporting objective length and/or girth outcomes, were included. Studies without primary data and conference abstracts were excluded. The main outcome measure was objective length and/or girth improvement. The review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. RESULTS: Out of 220 unique records, a total of 57 were reviewed. Eighteen studies assessed interventions for penile enhancement in 1764 healthy men complaining of small penis. Thirty-nine studies investigated 2587 men with concomitant pathologies consisting mostly of Peyronie's disease and erectile dysfunction. Twenty-five studies evaluated non-invasive interventions and 32 studies assessed surgical interventions, for a total of 2192 and 2159 men, respectively. Non-invasive interventions, including traction therapies and injection of fillers, were safe and mostly efficacious, whereas surgical interventions were associated with minor complications and mostly increased penile dimensions and/or corrected penile curvature. Overall, the quality of studies was low, and standardized criteria to evaluate and report efficacy and safety of procedures, as well as patient satisfaction, were missing. CONCLUSION: The quality of the studies on penile enhancement procedures published in the last decade is still low. This prevents us from establishing recommendations based on scientific evidence regarding the efficacy and safety of interventions that are performed to increase the penis size for aesthetic or therapeutic indications.

OBJECTIVE: Evaluate outcomes of patients undergoing mesh explantation following partial mesh excision (PME) and complete mesh excision (CME). BACKGROUND: Ventral hernia repair (VHR) with mesh remains one of the most commonly performed procedures worldwide. Management of previously placed mesh during reexploration remains unclear. Studies describing PME as a feasible alternative have been limited. METHODS: The AHSQC registry was queried for VHR patients who underwent mesh excision. Variables used for propensity-matching included age, BMI, race, diabetes, COPD, OR time>2 hours, immunosuppressants, smoking, active infection, ASA class, elective case, wound classification, and history of abdominal wall infection. RESULTS: A total of 1904 VHR patients underwent excision of prior mesh. After propensity matching, complications were significantly higher (35% vs 29%, P = 0.01) after PME, including SSI/SSO, SSOPI, and reoperation. No differences were observed in patients with clean wounds, however in clean-contaminated, PME more frequently resulted in SSOPI (24% vs 9%, P = 0.02). In mesh infection/fistulas, higher rates of SSOPI (46% vs 24%, P = 0.04) and reoperation (21% vs 6%, P = 0.03) were seen after PME. Odds-ratio analysis showed increased likelihood of SSOPI (OR 1.5, 95% CI 1.05-2.14; P = 0.023) and reoperation (OR 2.2, 95% CI 1.13-4.10; P = 0.015) with PME. CONCLUSIONS: With over 350,000 VHR performed annually and increasing mesh use, guidelines for management of mesh during reexploration are needed. This analysis of a multicenter hernia database demonstrates significantly increased postoperative complications in PME patients with clean-contaminated wounds and mesh infections/fistulas, however showed similar outcomes in those with clean wounds.

OBJECTIVE: To assess the perioperative outcomes of holmium laser enucleation of the prostate (HoLEP) in real-life practice and investigate the factors influencing the safety and effectiveness of the technique. PATIENTS AND METHODS: Critical analysis of patients with benign prostate hyperplasia (BPH) treated with HoLEP over 10 years of routine practice in three hospitals. Analysed variables included: preoperative characteristics (prostate size, active antiplatelet/anticoagulant therapy, blood parameters. prostate-specific antigen (PSA) level, maximum urinary flow rate [Qmax ], and International Prostate Symptom Score [IPSS]), intraoperative variables (operation time, concomitant removal of bladder calculi, and complications), early postoperative outcomes (change in blood parameters, catheterisation time, and hospital stay), and 12-month follow-up outcomes (change in IPSS, PSA level, and Qmax ). RESULTS: The analysis included 963 patients, aged 48-91 years, with a mean (range) prostate size of 91 (35-247) mL. The mean (sd) operation time was 77 (29) min, and the hospital stay and catheterisation time were 4 (2) and 1.3 (2) days, respectively. In all, 56 patients (5.6%) required concomitant removal of bladder calculi and 36 (3.7%) were converted to open prostatectomy or transurethral resection of the prostate due to intraoperative complications. Patients had a significant decrease in haemoglobin and haematocrit, but no differences were seen between patients with and without anticoagulant/antiplatelet therapy and those with prostates ≥ and <100 mL. The concomitant removal of bladder calculi and having a prostate ≥100 mL resulted in a longer operation time, but did not influence the safety and effectiveness outcomes. CONCLUSIONS: HoLEP is suitable for real-life patients with BPH, irrespective of the presence of active treatment with anticoagulant/antiplatelet, bladder lithiasis or a prostate ≥100 mL.

BACKGROUND: Laser-based technologies have been commercially marketed as "wonder treatments" without a sufficient and adequate body of evidence. In addition, on July 30, 2018, the U.S. Food and Drug Administration issued a warning regarding the safety of the use of laser-based devices for the following indications: vaginal "rejuvenation" or cosmetic vaginal procedures, vaginal conditions and symptoms related to menopause, urinary incontinence, and sexual function. AIM: To perform a thorough review of the available literature regarding laser-based vaginal devices for the treatment of female genitourinary indications and summarize the results in several short statements according to the level of evidence. METHODS: A comprehensive review of the literature regarding laser treatments for gynecological indications was performed based on several databases. Eligible were studies that included at least 15 patients. OUTCOMES: Several aspects, including preclinical data, have been investigated. For each topic covered, data on laser-based devices were analyzed. RESULTS: Despite the high heterogeneity of studies and its limitations, the committee released several statements regarding the use of laser-based devices for genitourinary indications. CLINICAL IMPLICATIONS: Available data in the clinical setting are still poor, and the impact of these technologies on vaginal symptoms and signs has not been clearly established. STRENGTHS & LIMITATIONS: All studies have been evaluated by a panel of experts providing recommendations for clinical practice. CONCLUSION: It is too early in the evolution and research of laser-based devices to make decisive recommendations regarding vaginal treatments. There is grave need to carry out randomized controlled trials with proper design for safety reasons, possible harm, and short-/long-term benefits for the different indications studied.

INTRODUCTION: Radiofrequency (RF)-based treatment has been introduced as an esthetic alternative treatment for various medical indications without the scientific backup of a satisfactory body of evidence. Furthermore, the United States Food and Drug Administration issued a warning regarding the safety of energy-based technologies for indications such as vaginal "rejuvenation," cosmetic vaginal treatment, vaginal conditions related to menopause, and symptoms of urinary incontinence and sexual function on July 30, 2018. AIM: To perform a thorough review of the existing literature regarding RF-based vaginal devices for the treatment of female genitourinary indications and summarize the evidence available in a few short statements. METHODS: A thorough review of the literature regarding RF treatments for gynecological indications was performed based on several databases. Studies that included at least 15 patients were eligible for analysis. MAIN OUTCOME MEASURE: Efficacy of RF devices for different genitourinary indications. RESULTS: Although a high level of heterogeneity of studies poses a serious challenge, the committee reached a decision on several statements related to the use of RF-based devices for genitourinary indications. CLINICAL IMPLICATIONS: RF-based vaginal treatments have not been studied thoroughly enough in order to establish decisive recommendations regarding their safety and efficacy. STRENGTH & LIMITATIONS: These position statements have been established by a group of experts. The lack of strong evidence makes it difficult to give decisive recommendations. CONCLUSIONS: Further randomized controlled trials with proper methodology and design are required to establish both benefits and possible harm these treatments may have in both short and long term for all the different indications studied.

BACKGROUND: Store-operated calcium entry and its key players, stromal interaction molecule (STIM) and Orai calcium channels, have been proposed as emergent therapeutic targets in cardiovascular pathophysiology. We hypothesize alteration of STIM/Orai signaling in erectile dysfunction (ED). AIM: To evaluate the contribution of STIM/Orai to human penile tissue contraction and to analyze the influence of ED on STIM/Orai signaling at functional and expression levels in human penile vascular tissues. METHODS: Human penile resistance arteries (HPRA) and human corpus cavernosum (HCC) were dissected from cavernosal specimens from 30 organ donors without history of ED (No ED) and from 48 patients with ED undergoing penile prosthesis insertion and functionally evaluated in wire myographs and organ chambers, respectively. Expression of STIM-1, Orai1, and Orai3 in HCC was localized and quantified by immunofluorescence. MAIN OUTCOME MEASURES: The main outcome measures are functional responses in HCC and HPRA and STIM/Orai channel protein expression in human cavernosal tissue. RESULTS: Inhibition of Orai channels with YM-58483 (20 µM) significantly reduced norepinephrine-induced contractions in both HCC and HPRA from either No ED or ED subjects, but the effects were more marked in ED (-20.1 ± 5.9% vs -45.5 ± 13.2% and -15.9 ± 4.0% vs -31.4 ± 6.9% reduction in Emax to norepinephrine in HCC and HPRA, respectively). Thromboxane-induced contractions were reduced and neurogenic contractile and relaxant responses modulated by Orai inhibition in penile tissues from patients with ED. In fact, addition of YM-58483 concentration dependently relaxed precontracted HPRA and HCC. These relaxations were significantly more pronounced in tissues from patients with ED (EC50 7.5 vs 1.3 µM and 10.5 vs 1.3 µM, for HCC and HPRA, respectively). All HCC specimens displayed expression of STIM-1, Orai1, and Orai3. Significantly increased expression of Orai1 and Orai3 but not STIM-1 was observed in patients with ED. CLINICAL TRANSLATION: Inhibition of enhanced Orai activity in human penile vascular tissue could facilitate erectile responses, alleviating ED. STRENGTHS AND LIMITATIONS: Enhanced STIM/Orai activity contribution to penile smooth muscle tone in ED is demonstrated at functional and structural levels in human tissues from a representative sample of patients with ED and in comparison with healthy tissue. We cannot differentiate the specific contribution of risk factors associated with ED to hyperactivity of the Orai system. CONCLUSIONS: Orai channels significantly contribute to human penile smooth muscle contraction. Orai contribution to penile smooth muscle tone is functionally enhanced in ED accompanied by increased expression of Orai channels in cavernosal tissue. Orai inhibition could be a potential therapeutic strategy to reduce penile smooth muscle contraction in ED. Sevilleja-Ortiz A, El Assar M, García-Rojo E, et al.

BACKGROUND: A xenograft consisting of equine collagen coated with human fibrinogen and thrombin (TachoSil; Baxter, CA) has recently been introduced in grafting procedures for Peyronie's disease (PD). AIM: To describe the results of a multicenter prospective registry on patients with PD undergoing plaque incision or and grafting (PIG) or plaque excision and grafting (PEG) with collagen fleece TachoSil, to evaluate the efficacy and safety of this procedure. METHODS: A prospective non-controlled multicenter study of patients with PD was performed between May 2016 and March 2018. Patients from 10 centers with stable PD for at least 3 months, difficulties in sexual intercourse, normal erectile function with or without pharmacological treatment, curvature >45°, and/or penile shortening and/or complex deformities were included. All patients underwent PIG/PEG with collagen fleece TachoSil. OUTCOMES: The main outcome measure of this study were penile curvature correction (intraoperative), penile shortening (intraoperative), erectile function with the 5-item version of the International Index of Erectile Function (IIEF-5) and the Erection Hardness Score, subjective patient outcomes with non-validated questionnaires, and complications. RESULTS: A total of 52 patients were enrolled in the study. The mean (SD) preoperative penile curvature was 72.8° (17.0). PIG was the preferred technique (80.8%). Intraoperatively, complete curvature correction was achieved in 92.3%, and no significant penile shortening was recorded in 80.8% of subjects. Subjective penile shortening was reported in 83.3% of patients at 6 months. No objective measurement of penile curvature and length was recorded during follow-up. No statistically significant difference from the baseline was found in IIEF-5 and Erection Hardness Score at 3 or at 6 months, although 16.7% of men experienced a worsening of IIEF-5 scores and 14.3% required de novo phosphodiesterase type 5 inhibitor use. 6 months after surgery, 78.5% of men were satisfied with intervention. Swelling and ecchymosis/hematoma were the most common perioperative complications (40.4%). 2 cases (3.8%) of wound infection were recorded. At 6 months, 35.7% of patients reported mild penile hypesthesia. CLINICAL IMPLICATIONS: Our results confirm the high success rate of grafting with TachoSil, and the surgeon perceived low percentage of penile shortening. STRENGTH & LIMITATIONS: This is the first multicentre study on patients with PD undergoing grafting with TachoSil without concomitant placement of penile prosthesis. The main limitations are the short follow-up and the relatively small sample size. CONCLUSION: Grafting with TachoSil after PIG/PEG in patients with PD is an effective and safe procedure. Among the main advantages of this technique, there are ease of use of the graft and reduced operative time. Fernández-Pascual E, Manfredi C, Torremadé J, et al.

BACKGROUND: Despite advances in diagnostic imaging capabilities, little information exists concerning the impact of physical dimensions of a paraesophageal hernia (PEH) on intraoperative decision making. The authors hypothesized that computerized volumetric analysis and multidimensional visualization to measure hiatal defect area (HDA) and intrathoracic hernia sac volume (HSV) would correlate to operative findings and required surgical techniques performed. METHODS: Using volumetric analysis software (Aquarius iNtuition, TeraRecon, Inc), HDA and HSV were measured in PEH patients with preoperative computerized tomography (CT) scans, and used to predict the likelihood of intraoperative variables. Multidimensional rotation of images enabled visualization of the entire hiatal defect in a plane mimicking the surgeon's view during repair. The intrathoracic hernia sac was outlined producing volume measurements based on a summation of exact dimensions. RESULTS: A total of 213 PEHR patients had preoperative CT imaging, with 14.1% performed emergently. Primary cruroplasty was performed in 89.2%, salvage gastropexy in 10.3%, and diaphragmatic relaxing incisions in 4.2%. Median HDA was 25.7 cm2 (IQR17.8-35.6 cm2); median HSV was 365.0 cm3 (IQR150.0-611.0 cm3). Incremental 5 cm2 increase in HDA was associated with greater likelihood of presenting emergently (OR 1.27; 95%CI 1.124-1.428, p = 0.0001), incarceration (OR 1.27; 1.074-1.499, p = 0.005), gastric volvulus (OR 1.13; 1.021-1.248, p = 0.02), and requiring either relaxing incision (OR 1.43; 1.203-1.709, p < 0.0001) or salvage gastropexy (OR 1.13; 1.001-1.274, p = 0.04). Similarly, HSV increases of 100 cm3 were associated with 23% greater likelihood of emergent repair (CI 1.121-1.353, p < 0.0001), and were more likely to require a relaxing incision (OR 1.18; 1.043-1.339, p = 0.009) or salvage gastropexy (1.19; 1.083-1.312, p = 0.0003). CONCLUSIONS: Utilization of CT volumetric measurements is a valuable adjunct in preoperative planning, allowing the surgeon to anticipate complexity of repair and operative approach, as incremental increases in HSV by 100 cm3 and HDA by 5 cm2 are more likely to require complex techniques or bailout procedures and/or present emergently.

BACKGROUND: Conventional Percutaneous Lithotripsy (PCNL) has been an effective, successful and easy approach for especially > 1 cm sized calyceal stones however risks of complications and nephron loss are inevitable. Our aim is to compare the efficacy and safety of PCNL, MiniPerc (MP) and UltraMiniPerc (UMP) for lower calyceal stones between 1 and 2 cm with a multicenter prospective randomized study. METHODS: Between January 2015 and June 2018, 132 consecutive patients with single lower calyceal stone were enrolled. Patients were randomized in three groups; A: PCNL; B: MP; C: UMP. 44 patients for the Group A, 47 for Group B and 41 for Group C. Exclusion criterias were the presence of coagulation impairments, age of < 18 or > 75, presence of infection or serious comorbidities. Patients were controlled with computerized tomography scan after 3 months. A negative CT or an asymptomatic patient with stone fragments < 3 mm size were the criteria to assess the stone-free status. Patient characteristics, stone free rates (SFR) s, complications and re-treatment rates were analyzed. RESULTS: The mean stone size were 16.38, 16.82 and 15.23 mm respectively in Group A, B and C(p = 0.34). The overall SFR was significantly higher in Group A (86.3%) and B (82.9%) as compared to Group C (78%)(p < 0.05). The re-treatment rate was significantly higher in Group C (12.1%) and complication rates was higher in Group A (13.6%) as compared to others(p < 0.05). The hospitalization was significantly shorter in Group C compared to Group A (p = 0.04). CONCLUSIONS: PCNL and MP showed higher efficacy than UMP to obtain a better SFR. Auxiliary and re-treatment rates were higher in UMP. On the other hand for such this kind of stones PCNL had more complications. Overall evaluation favors MP as a better indication in stones 1-2 cm size.

The intraplaque injection of collagenase from Clostridium Histolyticum (CCH) was established as an effective therapeutic alternative for selected patients with Peyronie's disease (PD). There is no consensus on the use of pre-procedure anaesthesia. The aim of this pilot study was to assess the efficacy and safety of dorsal penile block before CCH injections in reducing procedure related pain. The treatment protocol described in the IMPRESS trials was adopted. The first injection of the first cycle was given without anaesthesia, while the second after penile block. After the administration of each injection, the pain related to the procedure was evaluated with the Wong-Baker-FACES® -Pain-Rating-Scale. Thirty patients were included. Mean age 56.7 (SD: 9.61) years. Mean basal penile curvature 59.37º (SD: 18.26). The mean pain value related to the procedure measured after the first injection of the first cycle (without anaesthesia) was 5.4 (SD: 2.13), while after the second injection (with anaesthesia) was 2.5 (SD: 1.92), (p < .001). The treatment was more painful in patients with dorsal plaques (mean:6.2) than in patients with lateral plaques (mean: 4.35) (p = .01). We can conclude that penile block before CCH injection in patients with PD seems an effective and safe measure to decrease the pain related to the procedure.

BACKGROUND: In the face of an increasingly aged population, surgical management in the elderly will rise. This study assesses the short-term outcomes of esophagectomies in octogenarians. MATERIAL AND METHODS: The National Surgical Quality Improvement Program database was queried for esophagectomy cases from 2005 to 2014. Patients aged <80 and ≥80 y were compared in univariate and multivariate analysis, controlling for confounding variables. RESULTS: Among 9354 esophagectomies, 4.3% were performed in patients aged ≥80 y. Ivor Lewis was the most common approach, comprising 43% of cases. Octogenarians more frequently had dependent functional status (P < 0.0001) and cardiovascular disease (P < 0.0001), whereas younger patients were more likely obese (P < 0.0001), smokers (P < 0.0001), and have excess preoperative weight loss (P = 0.0043). Compared to younger patients, in multivariate analysis, elderly patients were noted to have increased risk of 30-d mortality (odds ratio [OR] 1.67; confidence interval [CI] 1.03-2.67), discharge to facility (OR 3.08; CI 2.36-4.02), myocardial infarction (OR 2.49; CI 1.29-4.82), and pneumonia (OR 1.47; CI 1.12-1.910). However, regardless of age, dependent functional status demonstrated the strongest association with mortality (OR 3.41; CI 2.14-6.61). Within the elderly, each additional year above 80 y old increased the risk of discharge to a facility by 17% (OR 1.17; CI 1.04-1.30). Cases requiring nongastric intestinal conduit were also more likely to suffer from early mortality (OR 2.87; CI 1.87-4.40). CONCLUSIONS: Age is independently associated with multiple adverse outcomes, including mortality, discharge to facility, and postoperative cardiopulmonary complications. Functional dependence is even more so associated with poor outcomes. Careful selection of very elderly patients is required to minimize additional risk.

OBJECTIVES: To assess the impact of transrectal versus transperineal prostate biopsy on erectile function. METHODS: This was a single-center, observational, prospective study of consecutive patients who underwent a prostate biopsy (transrectal or transperineal/fusion biopsy). Study participants completed the International Index of Erectile Function-5 questionnaire before the procedure, and 3 and 6 months after. Prostatic biopsies were carried out following the standard procedure for both techniques. RESULTS: The study included 135 male patients with a mean age of 63.5 years. At baseline, 28 patients (21%) presented normal erectile function, whereas 107 patients (82%) presented erectile dysfunction, which was severe in four (3%), moderate in 49 (36%) and mild in 54 (40%), with an overall mean International Index of Erectile Function-5 score of 17.70. After 3 months, the rates were 29%, 3%, 27% and 38%, respectively (mean International Index of Erectile Function-5 score 17.95). At 6 months, the rates were 30%, 6%, 28% and 34%, respectively (mean International Index of Erectile Function-5 score of 17.77). No significant differences between pre- and post-biopsy International Index of Erectile Function-5 scores at 3 and 6 months were observed, even when analyzing transrectal and transperineal separately. The number of biopsy cores and number of previous biopsies did not influence the International Index of Erectile Function-5 scores. CONCLUSIONS: Our findings suggest that prostate biopsy technique, number of biopsy cores and history of previous biopsy do not significantly impact erectile function in the medium term up to 6 months.
