Impacto de la pandemia en la actividad de las unidades de cirugía reconstructiva urológica y de andrología en España durante el estado de alarma (COVID-19) en 2020: resultados de una encuesta nacional / The impact of COVID-19 pandemic on reconstructive urologic surgery and andrology Spanish units’ practice during the state of alarm in 2020: National survey

Introducción: El estado de alarma debido a la COVID-19 revolucionó la actividad asistencial y quirúrgica. Dentro de la enfermedad urológica, aquellas consideradas «demorables» como la andrológica y la reconstructiva sufrieron un retraso considerable en su atención. Material y métodos: En mayo de 2020, tras haber superado casi la primera ola de la pandemia y en pleno estado de alarma, se envió una encuesta con 24 ítems a 120 urólogos integrados en los Grupos de Cirugía Reconstructiva Urológica y Andrología de la Asociación Española de Urología (AEU) para conocer la repercusión asistencial sobre la actividad clínica y quirúrgica en ambas subespecialidades. Resultados: Se alcanzó una tasa de respuesta del 75,8% con 91 encuestas recibidas. Previo al estado de alarma, el 49,5% disponía de uno a 2 quirófanos semanales, el 71,4% afrontaba una lista de espera quirúrgica de entre 3 y 12 meses, y el 39,6% atendía entre 20 y 40 pacientes semanales en consulta. Durante el estado de alarma, el 95,6% recibió directrices sobre cirugías a realizar, priorizando la cirugía urgente y la oncológica. En el 85,7% de los centros no se realizó ninguna cirugía andrológica ni reconstructiva. Alrededor del 50% de las consultas no fueron presenciales, recurriendo a la telemedicina (teléfono o e-mail) en la mayoría de los casos. Conclusiones: Las repercusiones de la pandemia sobre las enfermedades andrológicas y las candidatas a cirugía reconstructiva fueron muy importantes. Tras casi 2 años del inicio de la pandemia, aún queda por determinar el verdadero impacto final en nuestro sistema sanitario (AU)

Introduction: In Spain the state of alarm secondary to COVID-19 dramatically changed the medical and surgical assistance activity of other pathologies. Regarding urological pathologies, those considered as «non-urgent» (andrology and reconstructive surgery) were postponed or even unattended. Material and methods: In May 2020, once the first COVID-19 wave was almost over and still in the state of alarm, a 24-item survey was sent to 120 urologists from the Andrology Group and the Urologic Reconstructive Surgery Group of the Spanish Urological Association (AEU). Its aim was to determine the impact on clinical and surgical practice in both subspecialties. Results: We observed a response rate of 75.8% with 91 answered surveys. Before the state of alarm, 49.5% of urologists had 1-2 weekly surgical sessions available, surgical waiting list was 3-12 months for the 71.4%, and 39.6% attended between 20-40 patients weekly in office. During the state of alarm, 95.6% were given any kind of surgical guidelines, prioritizing emergency and oncologic pathologies. In the 85.7% of the hospitals neither andrology nor reconstructive surgeries were performed. In office, around 50% of patients were attended not on-site, most of them through telemedicine (phone calls and e-mails). Conclusions The negative pandemic implications in relation to the andrology and reconstructive surgery pathologies were truly important. After almost 2 years from the start of the pandemic, the true final impact on our health system has yet to be determined (AU)

Surgical and minimally invasive treatment of ischaemic and non-ischaemic priapism: a systematic review by the EAU Sexual and Reproductive Health Guidelines panel.

Surgical treatments for ischemic priapism (IP) include shunts or penile implants. Non-ischemic priapism (NIP) is usually the result of penile/perineal trauma causing an arterial fistula and embolisation may be required. We conducted a systematic review on behalf of the EAU Sexual and Reproductive health Guidelines panel to analyse the available evidence on efficacy and safety of surgical modalities for IP and NIP. Outcomes were priapism resolution, sexual function and adverse events following surgery. Overall, 63 studies (n = 923) met inclusion criteria up to September 2021. For IP (n = 702), surgery comprised distal (n = 274), proximal shunts (n = 209) and penile prostheses (n = 194). Resolution occurred in 18.7-100% for distal, 5.7-100% for proximal shunts and 100% for penile prostheses. Potency rate was 20-100% for distal, 11.1-77.2% for proximal shunts, and 26.3-100% for penile prostheses, respectively. Patient satisfaction was 60-100% following penile prostheses implantation. Complications were 0-42.5% for shunts and 0-13.6% for IPP. For NIP (n = 221), embolisation success was 85.7-100% and potency 80-100%. The majority of studies were retrospective cohort studies. Risk of bias was high. Overall, surgical shunts have acceptable success rates in IP. Proximal/venous shunts should be abandoned due to morbidity/ED rates. In IP > 48 h, best outcomes are seen with penile prostheses implantation. Embolisation is the mainstay technique for NIP with high resolution rates and adequate erectile function.

What is the effectiveness of surgical and non-surgical therapies in the treatment of ischemic priapism in patients with sickle cell disease? A systematic review by the EAU Sexual and Reproductive Health Guidelines Panel.

Sickle cell disease (SCD) is an inherited hemoglobin disorder characterized by the occlusion of small blood vessels by sickle-shaped red blood cells. SCD is associated with a number of complications, including ischemic priapism. While SCD accounts for at least one-third of all priapism cases, no definitive treatment strategy has been established to specifically treat patients with SC priapism. The aim of this systematic review was to assess the efficacy and safety of contemporary treatment modalities for acute and stuttering ischemic priapism associated with SCD. The primary outcome measures were defined as resolution of acute priapism (detumescence) and complete response of stuttering priapism, while the primary harm outcome was as sexual dysfunction. The protocol for the review has been registered (PROSPERO Nr: CRD42020182001), and a systematic search of Medline, Embase, and Cochrane controlled trials databases was performed. Three trials with 41 observational studies met the criteria for inclusion in this review. None of the trials assessed detumescence, as a primary outcome. All of the trials reported a complete response of stuttering priapism; however, the certainty of the evidence was low. It is clear that assessing the effectiveness of specific interventions for priapism in SCD, well-designed, adequately-powered, multicenter trials are strongly required.

Outcomes of a multidisciplinary mechanical circulatory support network in cardiogenic shock in a centre without heart transplant program: A successful interprofessional coordination model.

BACKGROUND AND OBJECTIVE: Cardiogenic shock (CS) mortality remains very high and mechanical circulatory support (MCS) may provide an effective alternative of treatment in selected patients. The aim of this study is to analyse the results of a multidisciplinary team care program (including anaesthesiologists, cardiologists, cardiothoracic surgeons, and intensivists) in CS patients who required MCS, in a tertiary centre without a heart transplant (HT) program. METHODS: Prospective observational study that sought to analyse the characteristics and survival to discharge predictors in a consecutive CS patients cohort treated with MCS. RESULTS: A total of 48 patients were included. Mean age was 61 ± 14 years. Before MCS, 45.8% of the patients presented with cardiac arrest. A 54.2% 30-day survival and 45.8% overall survival to discharge, was found. Age and vasoactive-inotropic score were independent predictors of mortality. CONCLUSIONS: A multidisciplinary team-care based MCS program in CS patients is feasible and may achieve favourable results in a centre without HT program.

Initial experience with SelectMDx® in the diagnosis of prostate cancer in a real-world evidence clinical practice setting. / Experiencia inicial del uso de SelectMDx® en el diagnóstico de cáncer de próstata en un entorno de práctica clínica habitual «real-world evidence¼.

INTRODUCTION: The use of biomarkers in the detection of prostate cancer (PC) can decrease overdiagnosis and overtreatment of non-significant PC. We analyze the usefulness and applicability of the SelectMDx® marker in a routine clinical practice setting. MATERIAL AND METHODS: Retrospective study of 48 patients evaluated by the SelectMDx® test between July 2017 and April 2019. Patients were stratified into two groups according to the risk estimated by the clinically significant CP test (CS-PC): <2% or 'very low risk', and >2%. Results were expressed based on previous prostate biopsy (PB) and multi-parametric magnetic resonance imaging (mpMRI) outcomes. RESULTS: Patients with negative PB and normal/doubtful mpMRI had <2% risk in 7/9 cases. Patients without PB and normal/doubtful mpMRI had <2% risk in 12/18 cases, and 2/6 cases with a >2% risk presented CS-PC. Of the 14 patients with no previous PB or mpMRI, 9 had <2% risk, and 2 cases were diagnosed with PC from the group of patients (5) with risk >2%. The number of patients in the remaining subgroups is too small to draw any conclusions. In all cases with pathological digital rectal examination, the test showed a >2% PC risk. CONCLUSION: SelectMDx® is a promising test for detecting patients with a very low risk of CS-PC, especially in patients with suspected PC, with or without negative PB, with normal/doubtful mpMRI. The presence of a pathological digital rectal examination may condition the result of the test.

Complex Peyronie's disease cases: surgery with or without penile prosthesis placement. / Casos complejos. Enfermedad de Peyronie: cirugía sin/con implante de prótesis de pene.

INTRODUCTION AND OBJECTIVE: Surgery is the treatment of choice for patients with Peyronie's disease presenting difficulty in penetration or erectile dysfunction without adequate response to therapy. Several techniques have been described, and urologists must be aware of their possible complications and sequelae in order to offer the patient the best possible alternative. PATIENTS AND METHODS: Three complex cases of patients with Peyronie's disease are presented. The first case exposes a complication after penile plication for the treatment of a major dorsal curve. The second case refers to difficult anal penetration secondary to a problem of erection direction after plaque incision surgery with oral mucosa grafting. The last case is a patient with a late post-operative complication of a three-piece prosthesis placement with plaque incision and equine collagen patch. RESULTS: Surgical options for each case are detailed and discussed. After patients were informed, the decision was taken in a consensual manner. CONCLUSIONS: Surgery for Peyronie's disease requires the urologist's consideration of the functional, aesthetic and psychological spheres. A systematic approach to all of these avoids complications, sequels and improves results.

Combination therapy for erectile dysfunction involving a PDE5 inhibitor and alprostadil.

The phosphodiesterase-5 inhibitors (PDE5Is) are the first-line treatment option for men with erectile dysfunction (ED), with alprostadil considered a second-line choice. Consideration has to be given to patients who fail these treatments and what their options are. This review evaluates the data on the combination of a PDE5I with alprostadil in patients who have previously failed therapy with either drug. A PubMed search was conducted and identified nine publications relating to combination treatment with alprostadil as intracavernosal, intraurethral or topical application. The results indicate that with all three formulations the combination therapy resulted in an improved outcome compared with either of the drugs as monotherapy. This was demonstrated by the increased total International Index of Erectile Function (IIEF) scores as well as IIEF erectile function domain scores. This finding was also valid for patients with post-prostatectomy ED. The associated side effects of the combined treatment did not result in treatment discontinuation. These findings suggest that combination therapy with a PDE5I and alprostadil might be considered a treatment option in patients who have previously had a poor response to either drug.

Focalyx Dx, Bx, Tx et Apps: A novel contemporary fusion paradigm for the management of prostate cancer.

FocalyxTM conceived as a response to emerging evidence data across numerous cancer lesions that questions current standard treatment approaches that too often lead to detrimental quality of life yet delivering limited survival benefit, especially in-lieu of advances in imaging technology applicable to cancer patients. The Focalyx paradigm aims to control cancer with improvement in quality of life. We initially devised 5 milestones: 1- Consistently optimize Prostate MRI imaging using the novel published protocols adopted as guidelines by societies such as the European Society of Urology and Radiology; 2- Evaluate fusion platform software solutions that existed; 3- Determine best fusión platform for Focalyx on practicality, precision, and workflow premises; 4- Evaluate commercially available FDA approved ablative technologies to implement our treatment vision; 5- Design a treatment option that can be performed in the office setting under local anesthesia, which would not impact negatively QOL outcomes of Prostate Cancer patients and seamless constant nonintrusive practical patient-physician interaction by the Focalyx app that facilitates follow up and provides early warning signals shall any change in the disease dynamics emerge. Prostate cancer was identified as the pilot disease for Focalyx to deliver a "GPS" like solution for the prostate gland that destroys identifiable disease without adverse effects such as: cancer anxiety, urinary incontinence, loss of erections and ejaculation. Since September of 2013, over 300 men have been accrued in NCT02381990- clintrials.gov evaluating the feasibility of our solutions for imaging (FocalyxDx), Biopsy (FocalyxBx) and Treatment (FocalyxTx). In this review we detail the tools available to achieve the Focalyx paradigm for men with Prostate Cancer.

Feasibility and safety of conservative surgery for the treatment of spermatic cord leiomyosarcoma.

OBJECTIVES: To assess the feasibility and the safety of conservative surgery to treat spermatic cord leiomyosarcoma. METHODS: Patients undergoing inguinoscrotal exploration in 10 different Urological Centers with diagnosis of leiomyosarcoma were enrolled. Preoperative evaluation included physical examination, Scrotal US, Abdominal CT and Scrotal MRI in selected cases. Patients underwent organ sparing surgery or orchiectomy in case of intraoperative FSE was positive for a local infiltration. Data collected were: age, presence of infiltration, length of the lesion, number of lesions, definitive histological outcome, pre and postoperative testosterone level. Follow up was performed with abdomen CT scan and scrotal US. RESULTS: From January 2007 to December 2013, 23 patients (mean age: 64.7 yrs) were diagnosed with spermatic cord leiomyosarcoma. Each patients underwent scrotal US. 10 patients underwent radical orchiectomy and 13 patients underwent conservative surgery. Mean follow up was 36.5 months. 5 patients (21.7%) developed a recurrent disease, 18 patients (78.3%) had a negative follow up (mean time: 40.8 months). Statistical analysis reveals that there is a significant correlation between number of lesions, length of the lesions and recurrent disease. CONCLUSIONS: Spermatic cord leiomyosarcoma is a rare disease. Conservative surgical treatment of spermatic cord leiomyosarcoma is a feasible therapeutic option for small, single and not infiltrating lesion.

Association of perioperative blood transfusion with oncologic outcomes after radical nephroureterectomy for upper tract urothelial carcinoma.

BACKGROUND: To test the hypothesis that perioperative blood transfusion (PBT)impacts oncologic outcomes of patients treated with radical nephroureterectomy (RNU) for upper tract urothelial carcinoma (UTUC). METHODS: Retrospective analysis of 2492 patients with UTUC treated at 23 institutions with RNU between 1987 and 2007.Cox regression models addressed the association of PBT with disease recurrence, cancer-specific mortality and any-cause mortality. RESULTS: A total of 510 patients (20.5%) patients received PBT. Within a median follow-up of 36 months (Interquartile range: 55 months), 663 (26.6%) patients experienced disease recurrence, 545 patients (21.9%) died of UTUC and 884 (35.5%) patients died from any cause. Patients who received PBT were at significantly higher risk of disease recurrence, cancer-specific mortality and overall mortality than patients not receiving PBT in univariable Cox regression analyses. In multivariable Cox regression analyses that adjusted for the effects of standard clinicopathologic features, PBT did not remain associated with disease recurrence (HR: 1.11; 95% CI 0.92-1.33, p = 0.25), cancer-specific mortality (HR: 1.09; 95% CI 0.89-1.33, p = 0.41) or overall mortality (HR: 1.09; 95% CI 0.93-1.28, p = 0.29). CONCLUSIONS: In patients undergoing RNU for UTUC, PBT is associated with disease recurrence, cancer-specific survival or overall survival in univariable, but not in multivariable Cox regression analyses.

Diabetes mellitus without metformin intake is associated with worse oncologic outcomes after radical nephroureterectomy for upper tract urothelial carcinoma.

AIMS: Evidence suggests a detrimental effect of diabetes mellitus (DM) on cancer incidence and outcomes. To date, the effect of DM and its treatment on prognosis in upper tract urothelial carcinoma (UTUC) remains uninvestigated. We tested the hypothesis that DM and metformin use impact oncologic outcomes of patients treated with radical nephroureterectomy (RNU) for UTUC. METHODS: Retrospective analysis of 2492 patients with UTUC treated at 23 institutions with RNU without neoadjuvant therapy. Cox regression models addressed the association of DM and metformin use with disease recurrence, cancer-specific mortality and any-cause mortality. RESULTS: A total of 365 (14.3%) patients had DM and 194 (7.8%) patients used metformin. Within a median follow-up of 36 months, 663 (26.6%) patients experienced disease recurrence, 545 patients (21.9%) died of UTUC and 884 (35.5%) patients died from any cause. Diabetic patients who did not use metformin were at significantly higher risk of disease recurrence and cancer-specific death compared to non-diabetic patients and diabetic patients who used metformin. In multivariable Cox regression analyses, DM treated without metformin was associated with worse recurrence-free survival (HR: 1.44, 95% CI 1.10-1.90, p = 0.009) and cancer-specific mortality (HR: 1.49, 95% CI 1.11-2.00, p = 0.008). CONCLUSIONS: Diabetic UTUC patients without metformin use have significantly worse oncologic outcomes than diabetics who used metformin and non-diabetics. The possible mechanism behind the impact of DM on UTUC biology and the potentially protective effect of metformin need further elucidation.

Renal artery aneurysms.

A renal artery aneurysm is defined as a dilated segment of renal artery that exceeds twice the diameter of a normal renal artery. Although rare, the diagnosis and incidence of this entity have been steadily increasing due to the routine use of cross-sectional imaging. In certain cases, renal artery aneurysms may be clinically important and potentially lethal. However, knowledge of their occurrence, their natural history, and their prognosis with or without treatment is still limited. This article aims to review the recent literature concerning renal artery aneurysms, with special consideration given to physiopathology, indications for treatment, different technical options, post-procedure complications and treatment outcomes.
