ABSTRACT

The objective of this study was to evaluate and compare efficacy and safety of two different Disposable circumcision suture devices (DCSDs). A prospective comparative non-randomized multicenter study was performed between November 2019 and February 2023. Patients underwent circumcision using a DCSD (CircCurerTM or the ZSR® device) according to the surgeon preference and device availability. A total of 378 patients were circumcised; 184 using CircCurerTM and 194 patients using ZSR®. No differences in baseline characteristics were observed. CircCurer and ZSR Groups showed similar rates of operative time (7.7 ±2.1 vs 7.3 ±2.0 min), surgical site infection (1.1% Vs 1.5%), edema (13% Vs 8.2%), hematomas (2.7% Vs 1.1%), and postoperative pain (2.5 Vs 2.0 points). ZSR Group had a significantly higher rate of clip fallout (62.9% Vs 38%, p < 0.001). At 2 months, patients of both groups reported a median satisfaction of 9 (8-9) points. Main limitation consist in non-randomized study. DCSDs seem to be effective and safe, with short operative times, uncommon and mild complications, and high patient satisfaction. ZSR® device has a higher rate of spontaneous staple dropout.

ABSTRACT

Targeted therapy (TT) for prostate cancer (PCa) aims to ablate the malignant lesion with an adequate margin of safety in order to obtain similar oncological outcomes, but with less toxicity than radical treatments. The main aim of this study was to evaluate the recurrence rate (RR) in patients with primary localized PCa undergoing mpMRI/US fusion targeted cryotherapy (FTC). A secondary objective was to evaluate prostate-specific antigen (PSA) as a predictor of recurrences. We designed a prospective single-center single-cohort study. Patients with primary localized PCa, mono or multifocal lesions, PSA ≤ 15 ng/mL, and a Gleason score (GS) ≤ 4 + 3 undergoing FTC were enrolled. RR was chosen as the primary outcome. Recurrence was defined as the presence of clinically significant prostate cancer in the treated areas. PSA values measured at different times were tested as predictors of recurrence. Continuous variables were assessed with the Bayesian t-test and categorical assessments with the chix-squared test. Univariate and logistic regression assessment were used for predictions. A total of 75 cases were included in the study. Ten subjects developed a recurrence (RR: 15.2%), while fifty-six (84.8%) patients showed a recurrence-free status. A %PSA drop of 31.5% during the first 12 months after treatment predicted a recurrence with a sensitivity of 53.8% and a specificity of 79.2%. A PSA drop of 55.3% 12 months after treatment predicted a recurrence with a sensitivity of 91.7% and a specificity of 51.9%. FTC for primary localized PCa seems to be associated with a low but not negligible percentage of recurrences. Serum PSA levels may have a role indicating RR.

ABSTRACT

CONTEXT: Prostate-specific membrane antigen (PSMA) positron emission tomography/magnetic resonance imaging (PET/MRI) is a novel imaging technique with several potential applications in the prostate cancer (PCa) setting. OBJECTIVE: To perform a systematic review of the current evidence regarding the diagnostic performance of PSMA PET/MRI in patients with primary and recurrent PCa. EVIDENCE ACQUISITION: A comprehensive bibliographic search on the MEDLINE and Cochrane Library databases was performed in October 2020. The review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement. Studies were deemed eligible if they assessed patients with primary or recurrent PCa (P) undergoing PSMA PET/MRI (I) with or without comparison with other imaging techniques (C) in order to evaluate its diagnostic performance (O). Retrospective and prospective primary clinical studies were included. Results of previous meta-analyses were reported. EVIDENCE SYNTHESIS: A total of 23 original articles and three meta-analyses were included. Limited evidence on PSMA PET/MRI is available, especially in the setting of partial gland ablation. PET/MRI can be an effective imaging modality for detecting primary PCa, showing higher accuracy than multiparametric MRI alone. It provides accurate local staging of primary PCa; however, there are contradictory results in this context when its performance is compared with other imaging techniques. PET/MRI also shows high performance for restaging and detecting tumor recurrence, even at low prostate-specific antigen levels. CONCLUSIONS: PSMA PET/MRI could represent a valuable tool in the management of patients with primary and recurrent PCa. No specific recommendations can be provided. PATIENT SUMMARY: Encouraging data regarding the benefits of prostate-specific membrane antigen positron emission tomography/magnetic resonance imaging in patients with prostate cancer are emerging from the literature.

ABSTRACT

INTRODUCTION: Prostate cancer (PCa) is one of the most common cancers worldwide and a leading cause of cancer-related mortality. Although the diagnosis and treatment of prostate cancer has improved substantially in recent years, new molecular biomarkers are needed to further prolong survival and improve the quality of life in these patients. AREAS COVERED: This review analyzes the current evidence for prognostic and predictive molecular biomarkers that can be applied across different clinical scenarios, ranging from localized disease to metastatic castration-resistant PCa, with a particular emphasis on the biomarkers likely to become available in routine clinical practice in the near future. EXPERT OPINION: There is a growing need for molecular testing to identify the most indolent types of prostate cancer to help optimize treatment strategies and spare treatment in these patients when possible. Current trends in the treatment of prostate cancer underscore the unmet clinical need for biomarkers to improve decision-making in a challenging clinical setting.

ABSTRACT

AIM: To evaluate whether positron-emission tomography/computed tomography with 68Ga-PSMA (68Ga-PSMA PET/CT) influences the therapeutic management of patients with primary or recurrent prostate cancer (PCa). BACKGROUND: Although 68Ga-PSMA PET/CT is one of the best options for staging or restaging patients with PCa, its availability is still very limited in Spain. The present study reports the results of the first group of patients in Spain who underwent 68Ga-PSMA PET/CT imaging. MATERIALS AND METHODS: All patients (n = 27) with a histological diagnosis of PCa who underwent 68Ga-PSMA PET/CT prior to the definitive treatment decision at the only centre with this technology in Spain during 2017-2018 were included. Two nuclear medicine physicians and a radiologist reviewed the imaging studies. The clinical impact was assessed from a theoretical perspective, based on the treatment that would have been applied if no data from the 68Ga-PSMA PET/CT were available. RESULTS: Most patients (n = 26; 96%) had persistent disease or biochemical recurrence after radical prostatectomy, radiotherapy, or combined treatment. One patient underwent 68Ga-PSMA PET/CT imaging to stage high-risk PCa. Overall, 68Ga-PSMA PET/CT was positive in 19 patients (70.4%). In 68.75% of these patients, none of the other imaging tests-MRI, CT, or bone scans-performed prior to the 68Ga-PSMA PET/CT were able to detect the presence of cancerous lesions. Overall, the findings of the 68Ga-PSMA PET/CT led to a modification of the therapeutic approach in 62.96% of the patients in the study. CONCLUSIONS: 68Ga-PSMA PET/CT alters the therapeutic approach in a substantial proportion of patients with PCa.

ABSTRACT

OBJECTIVES: To compare the efficacy and safety of a combined treatment of percutaneous needle tunnelling (PNT) and a modified collagenase Clostridium histolyticum (CCH) protocol (PNT/CCH) vs the modified protocol alone (CCH) in the treatment of Peyronie's disease (PD). PATIENTS AND METHODS: A prospective registry of patients treated with a modified CCH protocol was maintained between June 2014 and February 2018. The last 50 patients received PNT as an adjuvant therapy (PNT/CCH), and their data were compared with those of the other 94 patients treated previously (CCH). PNT involves the creation of multiple holes made percutaneously in the plaque before each injection. The modified protocol consisted of two collagenase injections, at 1-week intervals, followed by penile modelling. Patients used penile traction therapy, tadalafil and pentoxifylline for the next 2 months and were followed up for 6 months. The main outcome was improvement of curvature. Secondary outcomes were improvements in erectile function, PD symptoms, stretched penile length and satisfaction. RESULTS: Improvement in curvature was greater in patients in the PNT/CCH group than in the CCH group (mean ± sd 19.2 ± 6.1° vs 12.7 ± 5.0°; P < 0.001 [36.2 ± 12.5% vs 28.1 ± 14.5%; P = 0.001]). Compared with baseline, both interventions were associated with significant improvement in secondary outcomes. The main complications were ecchymosis, bruising and penile pain, with no significant differences between groups. CONCLUSIONS: Treatment of PD with CCH using our modified protocol in combination with PNT is safe and more effective than the modified protocol alone, with the potential for improved cost-effectiveness.

ABSTRACT

INTRODUCTION: Patients with Peyronie's disease (PD) and erectile dysfunction (ED) concomitant with shortening or other malformations benefit from prosthesis implantation and penile lengthening procedures. AIM: To evaluate the safety and efficacy of a multi-incisional technique with penile prosthesis implantation with multiple corporeal incisions and collagen grafting for the surgical management of complex cases of PD with ED and severe penile shortening. METHODS: From February 2015-May 2018, 43 consecutive patients with complex PD were treated using this technique. Implantation of a penile prosthesis (malleable or inflatable [IPP]) together with multiple relaxing tunica albuginea incisions and grafting with a self-adhesive collagen-fibrin fleece (TachoSil, Baxter Healthcare) was performed in all patients by a single surgeon (J.I.M.S.). MAIN OUTCOME MEASURE: Penile length and curvature correction, operative time, and incidence of postoperative complications were recorded as outcome measures. Functional outcomes were measured with questionnaires (International Index of Erectile Function-5, Erection Hardness Score, modified Erectile Dysfunction Inventory of Treatment Satisfaction questionnaire, PD Questionnaire) before and 3 and 6 months after surgery. RESULTS: With a median follow-up of 21 months (range 10-31), mean postsurgical penile lengthening was 2.5 (range 1-5) cm, with an improvement in the Bother domain of the PD Questionnaire of 4.4 (range 2-5) points. The average operative time was 86.7 and 71.6 minutes for the IPP and malleable penile prosthesis procedure, respectively. No glans ischemia was recorded; however, 1 IPP infection and 1 delayed distal corporeal erosion were recorded. Hematoma or bruising was observed in 23.2% of patients. The modified Erectile Dysfunction Inventory of Treatment Satisfaction questionnaire was completed by 39 (90.7%) patients. Overall, 89.7% would recommend this surgery. Patient satisfaction with straightness and length was 94.9% and 82.1%, respectively. CLINICAL IMPLICATIONS: The described technique helps restoration of penile length and erectile function in patients with complex PD. STRENGTHS & LIMITATIONS: The strength of the study is that it offers a simple, easy-to-apply technique for surgeons to correct shortening and other malformations in patients with ED and complex PD. The study is limited by the small number of patients, the short follow-up period and the performance of the technique by a single high-volume implanter. CONCLUSION: The implantation of a penile prosthesis (malleable or inflatable) together with multiple incisions of the plaque/tunica albuginea and grafting with a collagen fleece is a safe and efficient treatment for patients with complex PD in addition to ED and significant shortening.

ABSTRACT

BACKGROUND: Low specificity of prostate-specific antigen results in a considerable number of unnecessary prostate biopsies in current practice. SelectMDx® predicts significant prostate cancer upon biopsy and is used to reduce the number of unnecessary initial prostate biopsies. Furthermore, potential overtreatment of insignificant prostate cancer can be reduced. Besides the diagnostic accuracy of the test, also the context in a specific country determines the potential health benefit and cost-effectiveness. Therefore, the health benefit and cost-effectiveness of SelectMDx were assessed in France, Germany, Italy, and Spain. SUBJECT AND METHODS: A decision model was used to compare the current standard of care in which men undergo initial prostate biopsy in case of an elevated prostate-specific antigen, to a strategy in which SelectMDx was used to select men for biopsy. Model inputs most relevant to each of the four countries were obtained. With use of the model long-term quality-adjusted life years (QALYs) and healthcare costs were calculated for both strategies. RESULTS: In all four countries, the SelectMDx resulted in QALY gain and cost savings compared with the current standard of care. In France, SelectMDx resulted in 0.022 QALYs gained and cost savings of €1217 per patient. For Germany, the model showed a QALY gain of 0.016 and a cost saving of €442. In Italy, the QALY gain and cost savings were 0.031 and €762. In Spain 0.020 QALYs were gained and €250 costs were saved. CONCLUSIONS: The results of the model showed that with SelectMDx, QALYs could be gained while saving healthcare costs in the initial diagnosis of prostate cancer. The significant presence of overtreatment in the current standard of care in all four countries was the main factor that resulted in the beneficial outcomes with SelectMDx.

ABSTRACT

In this bibliographic review we reexamine the different features in relation to indication, performance and interpretation of prostatic biopsy (PB). The main objective is to place methodological features involving PB in the current scientific scenario, establishing the correlation between the most relevant and analyzing the historic evolution this procedure has followed, particularly over the last two decades. Prostate biopsy has evolved to be a regular element in urologists` daily practice and its learning process has been simplified to the point it can be approached with adequacy during the first years of residency in Urology. This privileged position PB enjoys in daily practice and the performance obtained from it would have not been a reality without optimization of transrectal ultrasound or local anesthesia techniques, yet reviled in some forums, the real responsible of such success. The consensus reached in the various scientific associations, the clinical guidelines of which are widely consulted worldwide, is the best to support the current state of the art, being the starting point for the addition of new improvements to PB.

ABSTRACT

En esta revisión bibliográfica se repasan los distintos aspectos relacionados con la indicación, realización e interpretación de la biopsia de próstata (BP).El objetivo principal es situar los aspectos metodológicos que rodean a la BP en el escenario científico actual, correlacionando entre sí los más relevantes y analizando la evolución histórica que este procedimiento ha seguido, particularmente, en las dos últimas décadas. La BP ha pasado a ser un elemento habitual en la práctica diaria del urólogo y su aprendizaje se ha simplificado hasta el punto de ser abordado con suficiencia durante los primeros años de la residencia en Urología. Esta posición privilegiada de que disfruta la BP en la práctica diaria y el rendimiento que de ella se obtiene, no hubiera sido una realidad sin la optimización de la ecografía transrectal ni las técnicas de anestesia local, aún denostadas en algunos foros, pero verdareros responsables de este éxito. El consenso adquirido en las diferentes asociaciones científicas cuyas guías clínicas son ampliamente consultadas en todo el mundo, es el mejor apoyo para afianzar el estado del arte actual y suponen el punto de partida a la incorporación de nuevas mejoras a la BP(AU)

ABSTRACT

BACKGROUND: The prognostic significance of venous involvement and tumour thrombus level in renal cell carcinoma (RCC) remains highly controversial. In 2010, the American Joint Committee on Cancer (AJCC) and the Union International Centre le Cancer (UICC) revised the RCC staging system (7th edition) based on tumour thrombus level, differentiating the T stage of tumours limited to renal-vein-only involvement. OBJECTIVE: We aimed to evaluate the impact of tumour thrombus extension in a multi-institutional cohort of patients. DESIGN, SETTING, AND PARTICIPANTS: An international consortium of 11 institutions was established to retrospectively review a combined cohort of 1215 patients undergoing radical nephrectomy and tumour thrombectomy for RCC, including 585 patients with inferior vena cava (IVC) involvement or higher. MEASUREMENTS: Predictive factors of survival, including histology, tumour thrombus level, nodal status, Fuhrman grade, and tumour size, were analysed. RESULTS AND LIMITATIONS: A total of 1122 patients with complete data were reviewed. The median follow-up for all patients was 24.7 mo, with a median survival of 33.8 mo. The 5-yr survival was 43.2% (renal vein involvement), 37% (IVC below the diaphragm), and 22% with caval involvement above the diaphragm. On multivariate analysis, tumour size (hazard ratio [HR]: 1.64 [range: 1.03-2.59]; p=0.036), Fuhrman grade (HR: 2.26 [range: 1.65-3.1]; p=0.000), nodal metastasis (HR: 1.32 [range: 1.09-1.67]; p=0.005), and tumour thrombus level (HR: 2.10 [range: 1.53-3.0]; p=0.00) correlated independently with survival. CONCLUSIONS: Based on analysis of the largest known cohort of patients with RCC along with IVC and atrial thrombus involvement, tumour thrombus level is an independent predictor of survival. Our findings support the changes to the latest AJCC/UICC staging system.

ABSTRACT

El uso de la tecnología láser en el campo de la cirugía urológica ha vivido grandes avances en los últimos 20 años. Desde los comienzos de este siglo la tecnología robótica ha desembarcado de una manera decidida en nuestra especialidad y día tras día van siendo más y más las indicaciones en las cuáles está teniendo una implantación definitiva. Las actuales combinaciones del láser quirúrgico y los dispositivos robóticos, se pueden centrar en dos áreas claramente diferenciadas, pero posiblemente complementarias; la utilización del láser para guiar el procedimiento quirúrgico, lo que podríamos llamar «reconocimiento de estructuras» o «posicionamiento» y el uso de láser por su capacidad ablativa minimizando la pérdida sanguínea y aumentando la precisión de la resección. En este trabajo se revisan los artículos y aportaciones más recientes en la combinación de estas dos tecnologías (AU)


The use of laser technology in the field of urologic surgery has experienced great advances over the past 20 years. Since the beginning of this century robotic technology has landed in a determined manner in our specialty and every day will be more and more indications on what is going to have a final deployment. The current combination of laser and surgical robots, can be focused on two distinct areas, but possibly complementary, the use of lasers to guide the surgical procedure, what we might call «landmarks and structures recognition» or «positioning» and laser use because of its ablative ability minimizing blood loss and increasing the resection accuracy. This paper reviews most recent articles and contributions on the combination of these two technologies (AU)
