Management of Lymph Node-positive Penile Cancer: A Systematic Review.

CONTEXT: Lymph node (LN) involvement in penile cancer is associated with poor survival. Early diagnosis and management significantly impact survival, with multimodal treatment approaches often considered in advanced disease. OBJECTIVE: To assess the clinical effectiveness of treatment options available for the management of inguinal and pelvic lymphadenopathy in men with penile cancer. EVIDENCE ACQUISITION: EMBASE, MEDLINE, the Cochrane Database of Systematic Reviews, and other databases were searched from 1990 to July 2022. Randomised controlled trials (RCTs), nonrandomised comparative studies (NRCSs), and case series (CSs) were included. EVIDENCE SYNTHESIS: We identified 107 studies, involving 9582 patients from two RCTs, 28 NRCSs, and 77 CSs. The quality of evidence is considered poor. Surgery is the mainstay of LN disease management, with early inguinal LN dissection (ILND) associated with better outcomes. Videoendoscopic ILND may offer comparable survival outcomes to open ILND with lower wound-related morbidity. Ipsilateral pelvic LN dissection (PLND) in N2-3 cases improves overall survival in comparison to no pelvic surgery. Neoadjuvant chemotherapy in N2-3 disease showed a pathological complete response rate of 13% and an objective response rate of 51%. Adjuvant radiotherapy may benefit pN2-3 but not pN1 disease. Adjuvant chemoradiotherapy may provide a small survival benefit in N3 disease. Adjuvant radiotherapy and chemotherapy improve outcomes after PLND for pelvic LN metastases. CONCLUSIONS: Early LND improves survival in nodal disease in penile cancer. Multimodal treatments may provide additional benefit in pN2-3 cases; however, data are limited. Therefore, individualised management of patients with nodal disease should be discussed in a multidisciplinary team setting. PATIENT SUMMARY: Spread of penile cancer to the lymph nodes is best managed with surgery, which improves survival and has curative potential. Supplementary treatment, including the use of chemotherapy and/or radiotherapy, may further improve survival in advanced disease. Patients with penile cancer with lymph node involvement should be treated by a multidisciplinary team.

Systematic Review and Meta-analysis of Minimally Invasive Procedures for Surgical Inguinal Nodal Staging in Penile Carcinoma.

CONTEXT: There are several procedures for surgical nodal staging in clinically node-negative (cN0) penile carcinoma. OBJECTIVE: To evaluate the diagnostic accuracy, perioperative outcomes, and complications of minimally invasive surgical procedures for nodal staging in penile carcinoma. EVIDENCE ACQUISITION: A systematic review of the Medline, Embase, and Cochrane controlled trials databases and ClinicalTrials.gov was conducted. Published and ongoing studies reporting on the management of cN0 penile cancer were included without any design restriction. Outcomes included the false negative (FN) rate, the number of nodes removed, surgical time, and postoperative complications. EVIDENCE SYNTHESIS: Forty-one studies were eligible for inclusion. Four studies comparing robot-assisted (RA-VEIL) and video-endoscopic inguinal lymphadenectomy (VEIL) to open inguinal lymph node dissection (ILND) were suitable for meta-analysis. A descriptive synthesis was performed for single-arm studies on modified open ILND, dynamic sentinel node biopsy (DSNB) with and without preoperative inguinal ultrasound (US), and fine-needle aspiration cytology (FNAC). DSNB with US + FNAC had lower FN rates (3.5-22% vs 0-42.9%) and complication rates (Clavien Dindo grade I-II: 1.1-20% vs 2.9-11.9%; grade III-V: 0-6.8% vs 0-9.4%) in comparison to DSNB alone. Favourable results were observed for VEIL/RA-VEIL over open ILND in terms of major complications (2-10.6% vs 6.9-40.6%; odds ratio [OR] 0.18; p < 0.01). Overall, VEIL/RA-VEIL had lower wound-related complication rates (OR 0.14; p < 0.01), including wound infections (OR 0.229; p < 0.01) and skin necrosis (OR 0.16; p < 0.01). The incidence of lymphatic complications varied between 20.6% and 49%. CONCLUSIONS: Of all the surgical staging options, DSNB with inguinal US + FNAC had the lowest complication rates and high diagnostic accuracy, especially when performed in high-volume centres. If DSNB is not available, favourable results were also found for VEIL/RA-VEIL over open ILND. Lymphatic-related complications were comparable across open and video-endoscopic ILND. PATIENT SUMMARY: We reviewed studies on different surgical approaches for assessing lymph node involvement in cases with penile cancer. The results show that a technique called dynamic sentinel node biopsy with ultrasound guidance and fine-needle sampling has high diagnostic accuracy and low complication rates. For lymph node dissection in penile cancer cases, a minimally invasive approach may offer favourable postoperative outcomes.

European Association of Urology-American Society of Clinical Oncology Collaborative Guideline on Penile Cancer: 2023 Update.

CONTEXT: Penile cancer is a rare disease but has a significant impact on quality of life. Its incidence is increasing, so it is important to include new and relevant evidence in clinical practice guidelines. OBJECTIVE: To provide a collaborative guideline that offers worldwide physician and patient guidance for the management of penile cancer. EVIDENCE ACQUISITION: Comprehensive literature searches were performed for each section topic. In addition, three systematic reviews were conducted. Levels of evidence were assessed, and a strength rating for each recommendation was assigned according to the GRADE (Grading of Recommendations, Assessment, Development, and Evaluation) methodology. EVIDENCE SYNTHESIS: Penile cancer is a rare disease but its global incidence is increasing. Human papillomavirus (HPV) is the main risk factor for penile cancer and pathology should include an assessment of HPV status. The main aim of primary tumour treatment is complete tumour eradication, which has to be balanced against optimal organ preservation without compromising oncological control. Early detection and treatment of lymph node (LN) metastasis is the main determinant of survival. Surgical LN staging with sentinel node biopsy is recommended for patients with a high-risk (≥pT1b) tumour with cN0 status. While (inguinal) LN dissection remains the standard for node-positive disease, multimodal treatment is needed in patients with advanced disease. Owing to a lack of controlled trials and large series, the levels of evidence and grades of recommendation are low in comparison to those for more common diseases. CONCLUSIONS: This collaborative penile cancer guideline provides updated information on the diagnosis and treatment of penile cancer for use in clinical practice. Organ-preserving surgery should be offered for treatment of the primary tumour when feasible. Adequate and timely LN management remains a challenge, especially in advanced disease stages. Referral to centres of expertise is recommended. PATIENT SUMMARY: Penile cancer is a rare disease that significantly impacts quality of life. While the disease can be cured in most cases without lymph node involvement, management of advanced disease remains challenging. Many unmet needs and unanswered questions remain, underlining the importance of research collaborations and centralisation of penile cancer services.

En Bloc enucleation with early apical release technique using MOSES (En Bloc MoLEP) vs. classic En Bloc HoLEP: a single arm study comparing intra- and postoperative outcomes.

BACKGROUND AND PURPOSE: We aimed to describe the technique and outcomes of En-Bloc MOSES laser enucleation of the prostate (En-Bloc MoLEP) with early apical release comparing it to En-Bloc HoLEP (non-MOSES). PATIENTS AND METHODS: This is a single-arm prospective study, using a historical control. n = 80 patients were enrolled to the En Bloc MoLEP group and compared to a retrospective group of n = 137 patients treated by En Bloc HoLEP (non-MOSES), in total n = 217 patients. RESULTS: En-Bloc MoLEP, showed to significantly improve the surgical time by 32% compared to non-MOSES HoLEP (32.16 ± 14.46 min, 47.58 ± 21.32, respectively; P = 0.003). Enucleation time, ablation rate and hemostasis time were also significantly improved (P < 0.001, for all three parameters). Enucleation time was 22.10 ± 9.27 min and 31.46 ± 14.85 min (P < 0.001), ablation rate 4.11 ± 2.41 and 2.54 ± 1.31 gr/min (P < 0.001), Hemostasis time 3.01 ± 2.50 and 8.35 ± 5.38 min (P < 0.001), for En Bloc MoLEP and En Bloc HoLEP, respectively. Q-max, PVR, PSA and IPSS showed significant improvement, however, at 12 months no significant differences were observed comparing both groups. CONCLUSIONS: En-Bloc MoLEP was significantly better than En-Bloc HoLEP in terms of surgical time, enucleation time, ablation rate and hemostasis time. However, large comparative RCT with long-term follow-up are needed.

What Is the Most Effective Management of the Primary Tumor in Men with Invasive Penile Cancer: A Systematic Review of the Available Treatment Options and Their Outcomes.

Context: The primary lesion in penile cancer is managed by surgery or radiation. Surgical options include penile-sparing surgery, amputative surgery, laser excision, and Moh's micrographic surgery. Radiation is applied as external beam radiotherapy (EBRT) and brachytherapy. The treatment aims to completely remove the primary lesion and preserve a sufficient functional penile stump. Objective: To assess whether the 5-yr recurrence-free rate and other outcomes, such as sexual function, quality of life, urination, and penile preserving length, vary between various treatment options. Evidence acquisition: The EMBASE, MEDLINE, Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials (CENTRAL; Cochrane HTA, DARE, HEED), Google Scholar, and ClinicalTrials.gov were searched for publications from 1990 through May 2021. Randomized controlled trials, nonrandomized comparative studies (NRCSs), and case series (CSs) were included. Evidence synthesis: The systematic review included 88 studies, involving 9578 men from 16 NRCSs and 72 CSs. The cumulative mean 5-yr recurrence-free rates were 82.0% for penile-sparing surgery, 83.9% for amputative surgery, 78.6% for brachytherapy, 55.2% for EBRT, 69.4% for lasers, and 88.2% for Moh's micrographic surgery, as reported from CSs, and 76.7% for penile-sparing surgery and 93.3% for amputative surgery, as reported from NRCSs. Penile surgery affects sexual function, but amputative surgery causes more appearance concerns. After brachytherapy, 25% of patients reported sexual dysfunction. Both penile-sparing surgery and amputative surgery affect all aspects of psychosocial well-being. Conclusions: Despite the poor quality of evidence, data suggest that penile-sparing surgery is not inferior to amputative surgery in terms of recurrence rates in selected patients. Based on the available information, however, broadly applicable recommendations cannot be made; appropriate patient selection accounts for the relative success of all the available methods. Patient summary: We reviewed the evidence of various techniques to treat penile tumor and assessed their effectiveness in oncologic control and their functional outcomes. Penile-sparing as well as amputative surgery is an effective treatment option, but amputative surgery has a negative impact on sexual function. Penile-sparing surgery and radiotherapy are associated with a higher risk of local recurrence, but preserve sexual function and quality of life better. Laser and Moh's micrographic surgery could be used for smaller lesions.

Diagnostic and prognostic factors in patients with prostate cancer: a systematic review.

OBJECTIVES: As part of the PIONEER Consortium objectives, we have explored which diagnostic and prognostic factors (DPFs) are available in relation to our previously defined clinician and patient-reported outcomes for prostate cancer (PCa). DESIGN: We performed a systematic review to identify validated and non-validated studies. DATA SOURCES: MEDLINE, Embase and the Cochrane Library were searched on 21 January 2020. ELIGIBILITY CRITERIA: Only quantitative studies were included. Single studies with fewer than 50 participants, published before 2014 and looking at outcomes which are not prioritised in the PIONEER core outcome set were excluded. DATA EXTRACTION AND SYNTHESIS: After initial screening, we extracted data following the Checklist for Critical Appraisal and Data Extraction for Systematic Reviews of prognostic factor studies (CHARMS-PF) criteria and discussed the identified factors with a multidisciplinary expert group. The quality of the included papers was scored for applicability and risk of bias using validated tools such as PROBAST, Quality in Prognostic Studies and Quality Assessment of Diagnostic Accuracy Studies 2. RESULTS: The search identified 6604 studies, from which 489 DPFs were included. Sixty-four of those were internally or externally validated. However, only three studies on diagnostic and seven studies on prognostic factors had a low risk of bias and a low risk concerning applicability. CONCLUSION: Most of the DPFs identified require additional evaluation and validation in properly designed studies before they can be recommended for use in clinical practice. The PIONEER online search tool for DPFs for PCa will enable researchers to understand the quality of the current research and help them design future studies. ETHICS AND DISSEMINATION: There are no ethical implications.

The waiting time for prostate cancer treatment in Italy: analysis from the PROS-IT CNR Study.

BACKGROUND: Prostate cancer (PCa) is the second most common neoplasm in male patients. To date, there's no certain indication about the maximum waiting time (WT) acceptable for treatment beginning and the impact on oncological and functional outcomes has not been well established. METHODS: Data from the National Research Council PCa monitoring multicenter project in Italy (Pros-IT CNR) were prospectively collected and analyzed. WT was defined as the time from the bioptical diagnosis of PCa to the first treatment received. Patients were divided in two groups, using a time frame of 90 days. Quality of life was measured through the Italian version of the University of California Los Angeles-Prostate Cancer Index (UCLA-PCI) and of the Short-Form Health Survey (SF-12). The occurrence of upgrading, upstaging, presence of lymph node metastasis and positive surgical margins at the final histopathological diagnosis, and PSA at 12 months follow-up were evaluated. RESULTS: The overall median WT was 93 days. The logistic multivariable model confirmed that age, being resident in Southern regions of Italy and T staging at diagnosis were significantly associated with a WT>90 days. At 6 months from diagnosis the mean SF-12 score for the emotional-psychological component was significantly lower in WT≥90 days group (P=0.0428). Among patients treated with surgical approach, no significant differences in oncological outcomes were found in the two groups. CONCLUSIONS: In our study age, clinical T stage and provenance from Southern regions of Italy are associated with a WT>90 days. WT might have no impact on functional and oncological outcome.

Contrast-enhanced ultrasound (CEUS) imaging for active surveillance of small renal masses.

PURPOSE: To assess the safety and efficacy of contrast-enhanced ultrasound (CEUS) imaging for monitoring small (< 4 cm) renal masses (SRM) in patients undergoing active surveillance (AS). METHODS: We retrospectively selected all consecutive patients with SRMs who underwent AS for at least 6 months at our Institution between January 2014 and December 2018. CEUS imaging was performed by two experienced genitourinary radiologists at established time points. The accuracy of CEUS for monitoring SRM size was compared with that of CT scan. For solid SRMs, four enhancement patterns (EP) were recorded. Radiological progression was defined as SRM growth rate ≥ 5 mm/year. RESULTS: Overall, 158/1049 (15.1%) patients with SRMs underwent AS. At a median follow-up of 25 months (IQR 13-39), no patient died due to renal cell carcinoma (RCC). No patients experienced CEUS-related adverse events. There was a large variability in the pattern of growth of SRMs (overall median growth rate: 0.40 mm/year), with 9.5% of SRMs showing radiological progression. The median SRM size was comparable between CEUS and CT scan examinations at all time points. The vast majority (92.7%) of SRMs did not show a change in their EP over time; and there was no association between the SRM's EP and radiological progression or SRM size. Overall, 43 (27.2%) patients underwent delayed intervention (DI); median SRM size, and median growth rate were significantly higher in these patients as compared to those continuing AS. CONCLUSION: In experienced hands, CEUS is a safe and effective strategy for active monitoring of SRMs in well-selected patients undergoing AS.

How radical prostatectomy procedures have changed over the last 10 years in Italy: a comparative analysis based on more than 1500 patients participating in the MIRROR-SIU/LUNA and the Pros-IT CNR study.

PURPOSE: Therapeutic strategies for prostate cancer (PCa) have been evolving dramatically worldwide. The current article reports on the evolution of surgical management strategies for PCa in Italy. METHODS: The data from two independent Italian multicenter projects, the MIRROR-SIU/LUNA (started in 2007, holding data of 890 patients) and the Pros-IT-CNR project (started in 2014, with data of 692 patients), were compared. Differences in patients' characteristics were evaluated. Multivariable logistic regression models were used to identify characteristics associated with robot-assisted (RA) procedure, nerve sparing (NS) approach, and lymph node dissection (LND). RESULTS: The two cohorts did not differ in terms of age and prostate-specific antigen (PSA) levels at biopsy. Patients enrolled in the Pros-IT-CNR project more frequently were submitted to RA (58.8% vs 27.6%, p < 0.001) and NS prostatectomy (58.4% vs. 52.9%, p = 0.04), but received LND less frequently (47.7% vs. 76.7%, p < 0.001), as compared to the MIRROR-SIU/LUNA patients. At multivariate logistic models, Lower Gleason Scores (GS) and PSA levels were significantly associated with RA prostatectomy in both cohorts. As for the MIRROR-SIU/LUNA data, clinical T-stage was a predictor for NS (OR = 0.07 for T3, T4) and LND (OR = 2.41 for T2) procedures. As for Pros-IT CNR data, GS ≥ (4 + 3) and positive cancer cores ≥ 50% were decisive factors both for NS (OR 0.29 and 0.30) and LND (OR 7.53 and 2.31) strategies. CONCLUSIONS: PCa management has changed over the last decade in Italian centers: RA and NS procedures without LND have become the methods of choice to treat newly medium-high risk diagnosed PCa.

The University of Florence Technique for Robot-Assisted Kidney Transplantation: 3-Year Experience.

Objective: To report the University of Florence technique for robot-assisted kidney transplantation (RAKT) from living donor (LD) and deceased donor (DD), highlighting the evolution of surgical indications and technical nuances in light of a single surgeon's learning curve. Materials and Methods: A dedicated program for RAKT from LDs was developed at our Institution in 2017 and implemented later with a specific framework for DDs. All RAKTs were performed by a single highly experienced surgeon. Data from patients undergoing RAKT between January 2017 and December 2019 were prospectively collected in a dedicated web-based data platform. In this report we provide a comprehensive step-by-step overview of our technique for RAKT, focusing on the potential differences in peri-operative and mid-term functional outcomes between LDs vs. DDs. Results: Overall, 160 KTs were performed in our center during the study period. Of these, 39 (24%) were performed with a robot-assisted laparoscopic technique, both from LDs (n = 18/39 [46%]) and from DDs (n = 21/39 [54%]). Eleven (11/39 [18%]), 13(13/39 [26%]), and 15 (15/39 [30%]) RAKTs were performed in 2017, 2018, and 2019, respectively, highlighting an increasing adoption of robotics for KT over time at our Institution. Median time for arterial (19 min for LD and 18 min for DD groups), venous (21 min for LD, 20 min for DD) and uretero-vesical (18 min for LD and 15 for DD) anastomosis were comparable between the two groups (all p > 0.05), as the median rewarming time (59 min vs. 56 min, p = 0.4). The rate of postoperative surgical complications according to Clavien-Dindo classification did not differ between the two study groups, except for Clavien-Dindo grade II complications (higher among patients undergoing RAKT from DDs, 76 vs. 44%, p = 0.042). Overall, 7/39 (18%) patients (all recipients from DDs) experienced DGF; two of them were on dialysis at last FU. Conclusions: Our experience confirms the feasibility, safety, and favorable mid-term outcomes of RAKT from both LDs and DDs in appropriately selected recipients, highlighting the opportunity to tailor the technique to specific recipient- and/or graft-characteristics. Further research is needed to refine the technique for RAKT and to evaluate the benefits and harms of robotics for kidney transplantation from DDs.

Robot-Assisted Laparoscopic Living Donor Nephrectomy: The University of Florence Technique.

Objective: To provide a step-by-step overview of the University of Florence technique for robotic living donor nephrectomy (LDN), focusing on its technical nuances and perioperative outcomes. Methods: A dedicated robotic LDN program at our Institution was codified in 2012. Data from patients undergoing robotic LDN from 2012 to 2019 were prospectively collected. All robotic LDNs were performed by a highly experienced surgeon, using the da Vinci Si robotic platform in a three-arm configuration. In this report we provide a detailed overview of our surgical technique for robotic LDN. The main objective of the study was to evaluate the technical feasibility and safety of the technique, including perioperative surgical complications rate and mid-term functional outcomes. Results: Overall, 36 patients undergoing robotic LDNs were included in the study. Of these, 28 (78%) were left LDNs. Median (IQR) donor pre-operative eGFR was 88 (75.6-90) ml/min/1.73 m2. In all cases, robotic LDN was completed without need of conversion. The median (IQR) overall operative time was 230 (195-258) min, while the median console time was 133 (IQR 117-166) min. The median (IQR) warm ischemia time was 175 (140-255) s. No intraoperative adverse events or 90-d major surgical complications were recorded. At a median (IQR) follow-up of 24 months (IQR 11-46), median (IQR) eGFR patients undergoing in living donor nephrectomy was 57.4 (47.9; 63.9) ml/min/1.73 m2. Conclusions: In our experience, robotic LDN is technically feasible and safe. The use of robotic surgery for LDN may provide distinct advantages for surgeons while ensuring optimal donors' perioperative and functional outcomes.

Robot-Assisted Nephron-Sparing Surgery for Cystic Nephroma in a Pediatric Patient: A Case Report.

Cystic nephroma is a benign kidney tumor, which presents as a unilateral cystic mass without solid elements. We presented the first case of cystic nephroma treated with robotic nephron-sparing surgery in a pediatric patient. The procedure adopted was the robot-assisted simple enucleation of the lesion, without arterial clamping.

Development of a robot-assisted kidney transplantation programme from deceased donors in a referral academic centre: technical nuances and preliminary results.

OBJECTIVE: To report the development of the first robot-assisted kidney transplantation (RAKT) programme from deceased donors, examining technical feasibility and early perioperative and functional outcomes at a referral academic centre. PATIENTS AND METHODS: A RAKT programme was developed in 2016 at our institution following structured modular training. Specific inclusion/exclusion criteria for both living and deceased donors were set. Data from patients undergoing RAKT from January 2017 to April 2018 were prospectively collected in an a priori developed web-based data set. RAKT followed the principles of the Vattikuti Urology Institute-Medanta technique, with specific technical modifications based on clinical recipient characteristics, as well as surgeon's skills and preference during the learning curve. Technical feasibility of RAKT from deceased donors and evaluation of perioperative and early functional outcomes were the main study endpoints. RESULTS: In all, 17 RAKTs were performed during the study period. Of these, six were from living donors and 11 were from deceased donors. All RAKTs were successfully completed without need of conversion. The median (interquartile range [IQR]) console time was 190 (160-220) min and the median (IQR) estimated blood loss was 120 (110-140) mL. The median times to complete venous, arterial and uretero-vesical anastomoses were 21, 22 and 21 min, respectively. The median (IQR) length of stay was 8 (6-12) days. At a median (IQR) follow-up of 8 (6-11) months, five (30%) complications were recorded. Of these, four (24%) were minor (Clavien-Dindo Grade I-II) and one major (Clavien-Dindo Grade IIIb, requiring graft nephrectomy). Overall, two patients were still on dialysis at last follow-up. A significant improvement in graft function was recorded progressively at all postoperative time points. CONCLUSION: Our preliminary experience outlines that: (i) the development of a RAKT programme is feasible in centres experienced in robotic surgery and open kidney transplantation; (ii) RAKT from deceased donors is feasible from both a technical and logistical perspective; and (iii) RAKT from deceased donors appears to achieve favourable early postoperative and functional outcomes. Larger studies with longer follow-up are needed to confirm these findings and compare the outcomes of RAKT from deceased donors with those from living donors.

Surgical management of a rare case of giant penile cancer.

Primary penile cancer is a rare malignant disease. In most cases, it presents as a clinically obvious lesion leading to early diagnosis in most patients. However, even in developed Countries, it carries a significant social stigma leading to diagnosis at locally advanced stages in a non-negligible proportion of patients. Yet, bulky penile lesions are becoming extremely rare in current clinical practice. We present a case of a patient with a giant primary penile cancer managed with radical penectomy, bilateral inguinal lymphadenectomy and perineal urethrostomy, who experienced disease recurrence six months after surgery and died with metastatic disease after denial of further treatment. The management of our case was challenging due to the extremely late diagnosis, the huge dimensions and the infiltrative nature of the tumor; however, from a histopathological perspective, the cancer itself did not display any microscopic peculiarity. Our case highlights that such bulky penile tumors can still occur in current urologic practice and require complex salvage surgical interventions in the context of a multidisciplinary setting.

Intraoperative assessment of ureteral and graft reperfusion during robotic kidney transplantation with indocyanine green fluorescence videography.

BACKGROUND: The aim of this paper is to report the first preliminary experience with intraoperative indocyanine green (ICG) fluorescence videography (IFV) to assess graft and ureteral reperfusion during robot-assisted kidney transplantation (RAKT). METHODS: We prospectively collected data from consecutive patients undergoing RAKT and IFV from living-donors at our Institution between January 2017 and April 2018. RAKT was performed following the principles of the Vattikuti-Medanta technique. ICG was injected intravenously after vascular anastomoses to quantitate graft and ureteral fluorescence signal. The signal intensity within selected intraoperative snapshots was evaluated for renal parenchyma, ureter and vascular anastomoses. A systematic review of the English-language literature about the topic was performed according to the PRISMA statement recommendations. RESULTS: Six patients were included. Neither conversions to open surgery nor major intra- or postoperative complications were recorded. At a median follow-up of 12 months (IQR 8-13), median estimated glomerular filtration rate was 64.2 mL/min/1.73 m2 (IQR 45.3-98.4). Intraoperative quantitative assessment of ICG fluorescence was successful in all patients. Of the five studies selected by our review, mostly prospective studies, all including open KT series. Yet, most studies were limited by lack of quantitative measures of IFV fluorescence. CONCLUSIONS: IFV during RAKT is feasible and safe and provides a reliable assessment of graft reperfusion. Larger studies are needed to standardize the technique and to evaluate the association between fluorescence signal, ultrasound parameters and postoperative kidney function.

Robotic Kidney Transplantation from a Brain-Dead Deceased Donor in a Patient with Autosomal Dominant Polycystic Kidney Disease: First Case Report.

Background: Autosomal dominant polycystic kidney disease (ADPKD) is a common cause of end-stage renal disease (ESRD) and may pose significant technical challenges for kidney transplantation. Recently, robot-assisted kidney transplantation (RAKT) has been shown to achieve excellent patient and graft outcomes while reducing surgical morbidity. However, the vast majority of RAKT performed so far were from living donors and no studies reported the outcomes of RAKT in patients with ADPKD. Case Presentation: Herein, we describe the first successful case of RAKT from a brain-dead deceased donor in a 37-year-old patient with ESRD due to ADPKD. Conclusion: Our case highlights that RAKT can be safely performed by experienced robotic surgeons even in selected complex recipients such as patients with ADPKD and using grafts from deceased donors.

Predictive Factors of Patients' and Their Partners' Sexual Function Improvement After Collagenase Clostridium Histolyticum Injection for Peyronie's Disease: Results From a Multi-Center Single-Arm Study.

BACKGROUND: Collagenase Clostridium histolyticum (CCH; Xiapex) injections represent the only licensed medical treatment for Peyronie's disease (PD). AIM: To evaluate the efficacy and safety of CCH injections in men with stable PD, using a modified treatment protocol and to assess partners' bother improvement in a large cohort of White-European sexually active heterosexual men treated in a single tertiary-referral center. METHODS: All the 135 patients enrolled underwent a thorough assessment, which included history taking, physical examination, and pharmacologically induced artificial erection test (intra-cavernous injection) to assess the degree of penile curvature (PC) at baseline and after the completion of the treatment. Patients with calcified plaque and/or ventral curvature were excluded. All patients underwent a modified treatment protocol, which consisted of 3 intra-lesional injections of 0.9 mg of CCH performed at 4-week intervals at the point of maximum curvature. After each injection, patients were instructed to follow a strict routine involving daily penile stretching in the intervals between injections. OUTCOMES: International Index of Erectile Function (IIEF)-15, Global Assessment of PD, PD questionnaires (PDQ), and Female Sexual Function Index (FSFI) questionnaire were performed at baseline and at the end of treatment. RESULTS: Overall, 135 patients completed the study protocol. Before treatment, 18 (13.33%) partners showed a degree of sexual dysfunction. Baseline median IIEF-15, FSFI, and PDQ scores were, respectively, 59.0, 35.0, and 23.0. Overall, both IIEF-total and all domains significantly improved after treatment (all P < .01). A PC mean change of 19.07 (P = .00) was measured. At the univariate linear regression analysis, IIEF-15, IIEF-erectile function, IIEF-sexual desire, and IIEF-intercourse satisfaction were positively associated with FSFI (all P ≤ .03); conversely, PDQ-penile pain, PDQ-symptom bother, and post-treament penile curvature (P ≤ .04) were associated with a decreased FSFI score. Furthermore, median change of PC was significantly associated with median change of FSFI (r = 0.25; 95% CI 0.02-0.11; P = .004). Global satisfaction after treatment was 89.6% (121/135). CLINICAL TRANSLATION: This modified CCH treatment protocol could improve both patients' and partner's sexual function. STRENGTH AND LIMITATIONS: This was an open-label, single-arm clinical study, without placebo. where only heterosexual couples in stable relationships were included. Furthermore, no real assessment of female sexual distress was carried out and long-term sexual function in both patients and female partners were not taken into account. CONCLUSIONS: The modified treatment schedule with CCH injections for stable PD has a positive impact on both patients' and partners' sexual function in heterosexual couples with a stable sexual relationship.

Impact of the off-clamp endoscopic robot-assisted simple enucleation (ERASE) of clinical T1 renal tumors on the postoperative renal function: Results from a matched-pair comparison.

PURPOSE: To evaluate the surgical and functional outcomes of a matched-paired series of on-clamp vs off-clamp endoscopic robot-assisted simple enucleation (ERASE) and standardized renorraphy in a tertiary referral institution, to search for predictors of functional drop after surgery and to investigate the influence of off-clamp technique in patients presenting these characteristics. MATERIALS AND METHODS: A matched-pair comparison of 120 on-clamp vs 120 off-clamp over 491 patients treated with ERASE was performed. Perioperative and functional outcomes were compared between groups. RESULTS: Patients treated with on-clamp and off-clamp technique had comparable complication and positive surgical margin rate. The off-clamp group had a significantly lower eGFR drop compared to the on-clamp group at 3rd postoperative day (POD) (1% vs 7%, p = 0.0001) and at 30th POD (2.5% vs 9%, p = 0.01) from baseline. This difference lost its statistical significance at 6th month and at last follow-up (median 40 months). At multivariable analysis the Charlson comorbidity index (OR 2.06, p < 0.0001), uncontrolled type 2 diabetes mellitus (OR 4.13, p < 0.001) were independent predictive factors of a >15% eGFR drop from baseline to last follow-up. In a subanalysis over 64 comorbid patients, those patients who underwent off-clamp ERASE had a significantly lower eGFR drop compared to the comorbid counterpart during the whole follow-up. CONCLUSIONS: The off-clamp ERASE is a safe surgical technique with a significantly lower renal function drop compared to on-clamp ERASE in the early perioperative time. Patients with comorbidity might represent a subgroup of patients having a functional benefit after off-clamp RAPN even in the long-term period.

Sexual Rehabilitation After Nerve-Sparing Radical Prostatectomy: Free-of-Charge Phosphodiesterase Type 5 Inhibitor Administration Improves Compliance to Treatment.

BACKGROUND: In December 2006, the region of Tuscany (Italy) authorized the free-of-charge provision of phosphodiesterase type 5 inhibitors (PDE5I) for all patients with Tuscan citizenship who undergo nerve-sparing radical prostatectomy (NSRP). OBJECTIVE: To compare sexual rehabilitation outcomes in patients with low risk of erectile dysfunction and minimal comorbidities who received PDE5Is free of charge (PDE5I-F) with those who paid for PDE5Is (PDE5I-P) after bilateral NSRP. METHODS: We reviewed prospectively recorded clinical data of 2,368 patients with Tuscan (PDE5I-F) and non-Tuscan (PDE5I-P) citizenship treated with NSRP at 3 different institutions in Tuscany from 2008 to 2013. Inclusion criteria for the final analysis were open or robot-assisted bilateral NSRP; low risk of postoperative erectile dysfunction according to the Briganti risk stratification tool; no smoking and no drug and alcohol abuse; no cardiovascular risk factors; no major surgery before and after NSRP; no neoadjuvant or adjuvant treatment; and no biochemical relapse. Dropout was defined as an interruption longer than 40 days of the treatment protocol indicated in the inclusion criteria. Treatment compliance was defined as more than 90% consumption of the prescribed PDE5I. OUTCOMES: The Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS) and the Italian version of the University of California-Los Angeles Prostate Cancer Index sexual function (UCLA-PCI-s) questionnaires were administered to assess patients' satisfaction with PDE5I treatment and sexual function. RESULTS: Overall, 648 patients in the PDE5I-F group and 182 in the PDE5I-P group met the inclusion criteria and were eligible for the study. Patients had comparable preoperative and surgical characteristics. The PDE5I-F group had a significantly higher early rehabilitation onset (P < .001), lower treatment dropout at 12, 24, and 36 months (P < .001 for all comparisons), and higher compliance to the treatment protocol at 6 and 12 months (P = .01 and P < .001, respectively). At multivariable analysis, the PDE5I-F protocol was an independent predictor of an EDITS score higher than 50 (hazard ratio = 1.54, P = .03) and a UCLA-PCI-s score higher than 50 (hazard ratio = 3.12, P = .01) after adjusting for the effects of several clinical features. CLINICAL IMPLICATIONS: The free-of-charge protocol has a significant impact on patients' satisfaction with PDE5I treatment. STRENGTHS AND LIMITATIONS: To our knowledge, this is the first study comparing free vs paid access to a sexual rehabilitation protocol. Major limitations are the observational nature of the study and the different population sizes of the 2 groups. CONCLUSIONS: In a selected cohort of patients after NSRP, free-of-charge access to a sexual rehabilitation protocol was significantly associated with higher early rehabilitation onset, major compliance to the protocol, minor treatment dropout, and higher satisfaction rate of patients.

Templates of Lymph Node Dissection for Renal Cell Carcinoma: A Systematic Review of the Literature.

Background: The role of lymph node dissection (LND) for renal cell carcinoma (RCC) is controversial. Notably, the conflicting evidence on the benefits and harms of LND is inherently linked to the lack of consensus on both anatomic templates and extent of lymphadenectomy. Herein, we provide a detailed overview of the most commonly dissected templates of LND for RCC, focusing on key anatomic landmarks and patterns of lymphatic drainage. Methods: A systematic review of the English-language literature was performed without time filters in July 2018 in accordance to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement recommendations. The primary endpoint was to summarize the most commonly dissected templates of LND according to the side of RCC. Results: Overall, 25 studies were selected for qualitative analysis. Of these, most were retrospective. The LND template was heterogeneous across studies. Indications and extent of LND were either not reported or not standardized in most series. The most commonly dissected template for right-sided tumors included hilar, paracaval, and precaval nodes, with few authors extending the dissection to the inter-aortocaval, retrocaval, common iliac or pre/paraaortic nodes. Similarly, the most commonly dissected template for left-sided tumors encompassed the renal hilar, preaortic and paraaortic nodes, with few authors reporting a systematic dissection of inter-aortocaval, retro-aortic, common iliac, or para-caval nodes. Conclusions: In light of the unpredictable renal lymphatic anatomy and the evidence from available prospective mapping studies, the extent of the most commonly dissected templates might be insufficient to catch the overall anatomic pattern of lymphatic drainage from RCC.
