Uncontrolled donation after circulatory death: A cohort study of data from a long-standing deceased-donor kidney transplantation program.

Despite good long-term outcomes of kidney transplants from controlled donation after circulatory death (DCD) donors, there are few uncontrolled DCD (uDCD) programs. This longitudinal study compares outcomes for all uDCD (N = 774) and all donation after brain death (DBD) (N = 613) kidney transplants performed from 1996 to 2015 at our center. DBD transplants were divided into those from standard-criteria (SCD) (N = 366) and expanded-criteria (N = 247) brain-dead donors (ECD). One-, 5-, and 10-year graft survival rates were 91.7%, 85.7%, and 80.6% for SCD; 86.0%, 75.8%, and 61.4% for ECD; and 85.1%, 78.1%, and 72.2% for uDCD, respectively. Graft survival was worse in recipients of uDCD kidneys than of SCD (P = .004) but better than in transplants from ECD (P = .021). The main cause of graft loss in the uDCD transplants was primary nonfunction. Through logistic regression, donor death due to pulmonary embolism (OR 4.31, 95% CI 1.65-11.23), extrahospital CPR time ≥75 minutes (OR1.94, 95%CI 1.18-3.22), and in-hospital CPR time ≥50 minutes (OR 1.79, 95% CI 1.09-2.93) emerged as predictive factors of primary nonunction. According to the outcomes of our long-standing kidney transplantation program, uDCD could help expand the kidney donor pool.

Effect of pelvic organ prolapse repair on detrusor overactivity in women following incontinence surgery: A multivariate analysis.

AIMS: To determine the effect of pelvic organ prolapse (POP) repair on post-operative detrusor overactivity (DO) in women who have underwent incontinence surgery, using multivariate analysis. METHODS: A retrospective study was carried out on a cohort of 105 women who underwent incontinence surgery. In 39 of the patients this surgery was associated with pelvic organ prolapse repair. Clinical and urodynamic data were collected pre- and 3 months post-operatively. A multivariate statistical analysis was performed to detect confounding factors which could influence on the risk factors associated with post-operative detrusor overactivity. RESULTS: On univariate analysis, the following pre-operative factors were associated with post-operative detrusor overactivity: symptomatic mixed urinary incontinence, rectocele, detrusor overactivity, voided volume on free uroflowmetry, maximum cystomanometric capacity, and performing concomitant pelvic organ prolapse repair. Multivariate analysis, by means of confounding factors elimination, revealed that only pre-operative rectocele and detrusor overactivity were independent risk factors. CONCLUSIONS: The pelvic organ prolapse repair acts as a confounding factor. Women with a pre-operative rectocele and detrusor overactivity are on a greater risk to develop post-operative detrusor overactivity and, therefore, they should be informed.

Post Pelvic Radiotherapy Affectation of the Lower Urinary Tract Peripheral Innervation in Men.

INTRODUCTION: The periurethral electromyography (EMGs) alterations in men who underwent pelvic radiotherapy (RT), either isolated or combined with surgery, have not been frequently described in the literature. OBJECTIVE: The study aimed to compare the EMG's data in men undergoing RT versus the non-irradiated control group. MATERIAL AND METHODS: The study included 61 consecutive males, who had undergone RT (27 of them had been operated) and 99 control consecutive patients who underwent a retrospective assessment. The EMGs were performed using a concentric electrode needle perineally, localizing the sphincter by visual and auditory signal (electromyograph MMS Solar Active). RESULTS: 14.8% denervation, 62.9% reinnervation, 14.9% denervation + reinnervation and 7.4% EMG normal. The age (p < 0.001) and neurogenic bladder data (p < 0.001) are risk factors. The smaller the prostate size (obtained by rectal examination) post-RT, the more the chance for an abnormal EMG (p < 0.001). The fact of having had received RT (p < 0.001) is the only risk factor. CONCLUSION: RT produces lesions over the pudendal nerve, showing denervation even in late periods. The surgery did not behave as a risk factor.

Robot Assisted Radical Prostatectomy in Kidney Transplant Recipients. Our Clinical Experience and a Systematic Review.

INTRODUCTION: Radical prostatectomy is a more skillful procedure in kidney graft recipients. Robotic surgery can provide a useful minimally invasive tool. OBJECTIVES: The study aims to evaluate the robotic-assisted laparoscopic prostatectomy (RALP) in kidney transplant recipients, describing intra/postoperative complications, renal and oncological outcomes. METHODS: This is a retrospective study conducted in a single institution of 84 RALP. Four of them were kidney transplant recipients. Side of the renal graft, clinical stage, intra/postoperative events, operating time, creatinine levels before/after intervention and oncologic follow-up were recorded. A systematic review of the literature was performed. RESULTS: Aged 61.25 ± 7.76 years, interval between renal transplantation and RALP: 10 ± 3.16 years. Mean prostate specific antigen: 7.1 ± 2.8 ng/ml, 2 patients were cT1c and 2 cT2a. Preoperative biopsies: Gleason score 3 + 3 in 3 patients, 3 + 4 in 1 patient. Charlson comorbidity index mean was 4.82 ± 0.82. No intra/postoperative events were reported. Mean operating time: 196 ± 20.8 min. Positive surgical margins: 2/4 patients. Pathological analysis: Gleason 3 + 4 in 2 patients and Gleason 3 + 3 in the others 2. A patient developed a bladder neck sclerosis. No differences between pre/postoperative creatinine. Three patients are free of biochemical recurrence and 1 patient required adjuvant radiotherapy. CONCLUSION: RALP in renal transplant recipients is a safe and feasible technique for localized prostate cancer. No difference in oncological outcomes and no impairments on renal function were found.

Leiomyoma of the seminal vesicles: laparoscopic excision.

Leiomyoma of the seminal vesicles is an extremely rare type of benign tumor of the genitourinary system and can cause lower urinary tract symptoms. Despite their low incidence, these tumors can be identified with transrectal ultrasound of the seminal vesicles during prostate examination. The removal of these tumors is facilitated by a laparoscopic approach.

Interest areas for training in endourology, laparoscopy and robotics: results of a multicentric survey among Spanish residents.

OBJECTIVES: To determine the current status of the training of Urology Resident's in Laparoscopic surgery, robotics and endourology. METHODS: We performed a survey among Spanish Urology Residents between 2011 and may 2012. We designed a survey that was disseminated through the web page of the Spanish Society of Laparoscopic and Robotic surgery (SECLA) (www.seclaendosurgery.com) to all residents from every Spanish hospital. The survey was divided in four blocks: General data, data of the Training Hospital, data of the surgical procedures (endoscopic, laparoscopic and robotic) and training features. We performed a descriptive study of the results. RESULTS: 36 Urology residents out of a total of 384 answered the survey (9,3%). In reference to endoscopic procedures 25% of the residents had never been involved on a percutaneous nephrostomy (n=36), and did not expect to do it. On the contrary, 77% have performed ureterorrenoscopy as first surgeon (n=36) and 25% have participated in more than 10 procedures. 54.4% of the participants took part as surgeons in percutaneous nephrolithotomies (n=28) and 79% looked forward to do them. Participation of residents in Da Vinci Robot assisted laparoscopic procedures is low. Laparoscopic procedures are very attractive and their participation is reduced as procedure complexity increases. CONCLUSIONS: 41.6% of participants think their training is adequate whereas 58,3% think it is not. 88% think their training could improve through courses and seminars and acquiring a greater degree of responsibility.

Benign prostatic hyperplasia. / Hiperplasia benigna de próstata.

Benign prostatic hyperplasia (BPH) is a histopathologic definition associated with enlargement of the prostate gland that causes obstruction of the lower urinary tract and manifests clinically with characteristic symptoms that are what bring patients for consultation. Urinary tract symptoms are common, especially in an increasingly aging population. Diagnosis and the decision on when and how to treat depend on the patient's quality of life and objective clinical parameters. An individualized, risk-based approach is necessary to guide conservative, pharmacologic, or surgical treatment.

Oncological outcomes in robot-assisted radical prostatectomy: the value of PSA density as a preoperative predictive factor.

Background: Pretreatment assessment of patients diagnosed with localized prostate cancer (PCa) is essential for therapeutic decision-making. Currently available staging systems based on prostate-specific antigen (PSA), Gleason score, and clinical stage allow for determining the prognostic characteristics of these patients. Several studies have evaluated the preoperative use of prostate-specific antigen density (PSAD) as a prognostic factor for further risk stratification. To date, the role of PSAD in this setting is still an object of debate. Objectives: The present analysis aimed to assess the predictive potential of PSAD for adverse oncological outcomes after robot-assisted radical prostatectomy (RARP) and to compare its accuracy to preoperative PSA (pPSA). Design and methods: We retrospectively reviewed 427 patients diagnosed with localized PCa who underwent RARP at a single institution between January 2015 and January 2020. Generating receiver operator characteristic (ROC) curves, calculating areas under the curves (AUCs), and using a linear regression model, we analyzed the association of PSAD and pPSA with postoperative positive surgical margins (PSM), Gleason score ⩾ 7, persistent PSA, and biochemical recurrence (BCR), with a median follow-up of 47 months. Results: PSAD showed a significant association with PSM (p < 0.0001), PSA persistence (p < 0.0001), and Gleason ⩾ 7 (p < 0.0001), without being statistically significant in predicting BCR (p = 0.098). The predictive value of PSAD was comparable to pPSA for outcomes of PSA persistence (AUC 0.727 versus 0.771) and Gleason ⩾ 7 (AUC 0.683 versus 0.649). Conclusion: PSAD is a predictive factor for postoperative oncological outcomes of PSM, Gleason score ⩾ 7, and persistence of PSA. Despite the need for further studies, PSAD could be useful as a prognostic parameter in conjunction with established staging systems.

Oncological outcomes in robot-assisted radical prostatectomy: the value of PSA density as a preoperative predictive factor Prostate-specific antigen density (PSAD) has an established role in the diagnostic process of prostate cancer (PCa). However, controversy remains on the assessment of its value as a pretreatment prognostic factor. The aim of our study was to evaluate the predictive ability of PSAD for oncological outcomes in PCa patients treated with robot-assisted radical prostatectomy (RARP) and to compare with the value of preoperative PSA (pPSA). The present analysis showed a significant association of PSAD with positive surgical margins (PSM), Gleason Score >=7 and prostate-specific antigen (PSA) persistence after RARP. Moreover, PSAD demonstrated to perform comparably to pPSA in predicting the outcomes of clinically significant PCa (csPCa) and post-RARP PSA persistence. Therefore, PSAD is considered a preoperative predictive factor potentially useful in conjunction with other previously established prognostic criteria and clinical features.

Predictive Models for Assessing Patients' Response to Treatment in Metastatic Prostate Cancer: A Systematic Review.

Background and objective: The treatment landscape of metastatic prostate cancer (mPCa) has evolved significantly over the past two decades. Despite this, the optimal therapy for patients with mPCa has not been determined. This systematic review identifies available predictive models that assess mPCa patients' response to treatment. Methods: We critically reviewed MEDLINE and CENTRAL in December 2022 according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses statement. Only quantitative studies in English were included with no time restrictions. The quality of the included studies was assessed using the PROBAST tool. Data were extracted following the Checklist for Critical Appraisal and Data Extraction for Systematic Reviews criteria. Key findings and limitations: The search identified 616 citations, of which 15 studies were included in our review. Nine of the included studies were validated internally or externally. Only one study had a low risk of bias and a low risk concerning applicability. Many studies failed to detail model performance adequately, resulting in a high risk of bias. Where reported, the models indicated good or excellent performance. Conclusions and clinical implications: Most of the identified predictive models require additional evaluation and validation in properly designed studies before these can be implemented in clinical practice to assist with treatment decision-making for men with mPCa. Patient summary: In this review, we evaluate studies that predict which treatments will work best for which metastatic prostate cancer patients. We found that existing studies need further improvement before these can be used by health care professionals.

Which Patients with Prostate Cancer and Lymph Node Uptake at Preoperative Prostate-specific Membrane Antigen Positron Emission Tomography/Computerized Tomography Scan Are at a Higher Risk of Prostate-specific Antigen Persistence After Radical Prostatectomy? Identifying Indicators of Systemic Disease by Integrating Clinical, Magnetic Resonance Imaging, and Functional Imaging Parameters.

BACKGROUND: The role of local therapies including radical prostatectomy (RP) in prostate cancer (PCa) patients with clinical lymphadenopathies on prostate-specific membrane antigen (PSMA) positron emission tomography/computerized tomography (PET/CT) has scarcely been explored. Limited data are available to identify men who would benefit from RP; on the contrary, those more likely to benefit already have systemic disease. OBJECTIVE: We aimed to assess the predictors of prostate-specific antigen (PSA) persistence in surgically managed PCa patients with lymphadenopathies on a PSMA PET/CT scan by integrating clinical, magnetic resonance imaging (MRI), and PSMA PET/CT parameters. DESIGN, SETTING, AND PARTICIPANTS: We identified 519 patients treated with RP and extended lymph node dissection, and who received preoperative PSMA PET between 2017 and 2022 in nine referral centers. Among them, we selected 88 patients with nodal uptake at preoperative PSMA PET (miTxN1M0). OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The outcome was PSA persistence, defined as a PSA value of ≥0.1 ng/ml at the first measurement after surgery. Multivariable logistic regression models tested the predictors of PSA persistence. Covariates consisted of biopsy International Society of Urological Pathology (ISUP) grade group, clinical stage at MRI, and number of positive spots at a PET/CT scan. A regression tree analysis stratified patients into risk groups based on preoperative characteristics. RESULTS AND LIMITATIONS: Overall, lymph node invasion (LNI) was detected in 63 patients (72%) and 32 (36%) experienced PSA persistence after RP. At multivariable analyses, having more than two lymph nodal positive findings at PSMA PET, seminal vesicle invasion (SVI) at MRI, and ISUP grade group >3 at biopsy were independent predictors of PSA persistence (all p < 0.05). At the regression tree analysis, patients were stratified in four risk groups according to biopsy ISUP grade, number of positive findings at PET/CT, and clinical stage at MRI. The model depicted good discrimination at internal validation (area under the curve 78%). CONCLUSIONS: One out of three miN1M0 patients showed PSA persistence after surgery. Patients with ISUP grade 2-3, as well as patients with organ-confined disease at MRI and a single or two positive nodal findings at PET are those in whom RP may achieve the best oncological outcomes in the context of a multimodal approach. Conversely, patients with a high ISUP grade and extracapsular extension or SVI or more than two spots at PSMA PET should be considered as potentially affected by systemic disease upfront. PATIENT SUMMARY: Our novel and straightforward risk classification integrates currently available preoperative risk tools and should, therefore, assist physician in preoperative counseling of men candidates for radical treatment for prostate cancer with positive lymph node uptake at prostate-specific membrane antigen positron emission tomography.

Pyeloureteral Anastomosis as a Reconstructive Technique for Post-Renal Transplant Ureteral Stenosis.

OBJECTIVE: Ureteral stenosis in renal transplant patients is a frequent urological complication that involves significant morbidity and may compromise graft function. Despite the common use of minimally invasive techniques, surgery continues to be the definitive treatment for ureteral stenosis, and pyeloureteral anastomosis is an infrequent but effective technique in the management of this pathology and has been described as a safe treatment with a low percentage of complications. METHODS: This is a retrospective study of patients in whom surgical intervention via pyeloureteral anastomosis was carried out in our center in the last 12 years. A descriptive analysis of perioperative management, complications, and functional results is provided. A comparison of renal function at diagnosis and after surgery was made to evaluate the effectiveness of the procedure. RESULTS: Thirteen patients underwent surgery within the described time frame. Time to diagnosis of stenosis was 60 days [interquartile range (IQR) 31-368]. Creatinine at diagnosis was 2.2 mg/dL [IQR 1.9-3] with a glomerular filtration rate, estimated by the modification of diet in renal disease equation, of 29 mL/min/1.73 m2 [IQR 22.6-34.5]. Of these patients, 92.3% underwent percutaneous nephrostomy, and 38.5% also had a ureteral catheter. The mean duration of surgery was 265 minutes [IQR 240-300], and hospital stay was 9 days [IQR 7.5-16]. A double J was placed in all cases, which was maintained for 36 days [IQR 30-49]. Postoperative complications occurred in 15.4% of patients. Serum creatinine 1 year after surgery was 1.6 ± 0.4 mg/dL. Among the patients, 76.9% had no new pyelocalyceal dilatation on follow-up Doppler ultrasound scans at a mean follow-up time of 12 months. The restenosis rate was 23.1%, and all were successfully treated by endoscopic approach. There was an improvement in renal function figures at 1, 3, 6, and 12 months compared to renal function at diagnosis, both in terms of serum creatinine and glomerular filtration rate, with statistically significant results. CONCLUSION: Pyeloureteral anastomosis as a reconstructive technique of the urinary tract in renal transplant patients is an effective and reproducible technique with good long-term results.

The Use of Radiomic Tools in Renal Mass Characterization.

The incidence of renal mass detection has increased during recent decades, with an increased diagnosis of small renal masses, and a final benign diagnosis in some cases. To avoid unnecessary surgeries, there is an increasing interest in using radiomics tools to predict histological results, using radiological features. We performed a narrative review to evaluate the use of radiomics in renal mass characterization. Conventional images, such as computed tomography (CT) and magnetic resonance (MR), are the most common diagnostic tools in renal mass characterization. Distinguishing between benign and malignant tumors in small renal masses can be challenging using conventional methods. To improve subjective evaluation, the interest in using radiomics to obtain quantitative parameters from medical images has increased. Several studies have assessed this novel tool for renal mass characterization, comparing its ability to distinguish benign to malign tumors, the results in differentiating renal cell carcinoma subtypes, or the correlation with prognostic features, with other methods. In several studies, radiomic tools have shown a good accuracy in characterizing renal mass lesions. However, due to the heterogeneity in the radiomic model building, prospective and external validated studies are needed.

A tumor-associated heparan sulfate-related glycosaminoglycan promotes the generation of functional regulatory T cells.

Functional Tregs play a key role in tumor development and progression, representing a major barrier to anticancer immunity. The mechanisms by which Tregs are generated in cancer and the influence of the tumor microenvironment on these processes remain incompletely understood. Herein, by using NMR, chemoenzymatic structural assays and a plethora of in vitro and in vivo functional analyses, we demonstrate that the tumoral carbohydrate A10 (Ca10), a cell-surface carbohydrate derived from Ehrlich's tumor (ET) cells, is a heparan sulfate-related proteoglycan that enhances glycolysis and promotes the development of tolerogenic features in human DCs. Ca10-stimulated human DCs generate highly suppressive Tregs by mechanisms partially dependent on metabolic reprogramming, PD-L1, IL-10, and IDO. Ca10 also reprograms the differentiation of human monocytes into DCs with tolerogenic features. In solid ET-bearing mice, we found positive correlations between Ca10 serum levels, tumor size and splenic Treg numbers. Administration of isolated Ca10 also increases the proportion of splenic Tregs in tumor-free mice. Remarkably, we provide evidence supporting the presence of a circulating human Ca10 counterpart (Ca10H) and show, for the first time, that serum levels of Ca10H are increased in patients suffering from different cancer types compared to healthy individuals. Of note, these levels are higher in prostate cancer patients with bone metastases than in prostate cancer patients without metastases. Collectively, we reveal novel molecular mechanisms by which heparan sulfate-related structures associated with tumor cells promote the generation of functional Tregs in cancer. The discovery of this novel structural-functional relationship may open new avenues of research with important clinical implications in cancer treatment.

Research protocol to identify progression and death amongst patients with metastatic hormone-sensitive prostate cancer treated with available treatments: PIONEER IMI's "big data for better outcomes" program.

Androgen deprivation therapy-based with or without first-generation anti-androgens, was the standard of care for patients with metastatic hormone-sensitive prostate cancer (mHSPC) for decades. However, the development of docetaxel chemotherapy and new androgen receptor-targeted agents, abiraterone acetate and prednisolone, apalutamide , enzalutamide and darolutamide (in combination with docetaxel chemotherapy) has proven that combination of treatments is more effective. Recently, intensification therapy, so-called "triplets", have emerged in the armamentarium of mHSPC treatment. Metastatic disease is a clinical state that remains poorly understood. The optimal diagnostic and management of patients with mHSPC are changing thanks to the development of new imaging techniques and therapies. The primary objective of this study is to develop and validate a predictive model for the occurrence of symptomatic progression, initiation of new treatments and death amongst patients with mHSPC treated with one of the approved treatment plans, on characteristics present at admission.

Navigating through the Controversies and Emerging Paradigms in Early Detection of Prostate Cancer: Bridging the Gap from Classic RCTs to Modern Population-Based Pilot Programs.

Over the last three decades, the European Randomized Study of Screening for Prostate Cancer (ERSPC) and the US-based Prostate, Lung, Colorectal and Ovarian (PLCO) Cancer Screening have steered the conversation around the early detection of prostate cancer. These two randomized trials assessed the effect of screening on prostate cancer disease-specific mortality. Elevated PSA levels were followed by a systematic sextant prostate biopsy. Standard repeat testing intervals were applied. After controversies from 2009 to 2016 due to contradicting results of the two trials, the results aligned in 2016 and showed that early PSA detection reduces prostate cancer-specific mortality. However, overdiagnosis rates of up to 50% were reported, and this sparked an intense debate on harms and benefits for almost 20 years. The balance between harms and benefits is highly debated and has initiated further research to investigate new ways of early detection. In the meantime, the knowledge and tools for the diagnostic algorithm improved. This is a continuously ongoing effort which focuses on individual risk-based screening algorithms that preserve the benefits of the purely PSA-based screening algorithms, while reducing the side effects. An important push towards investigating new techniques for early detection came from the European Commission on the 20th of September 2022. The European Commission published its updated recommendation to investigate prostate, lung, and gastric cancer early detection programs. This opened a new window of opportunity to move away from the trial setting to population-based early detection settings. With this review, we aim to review 30 years of historical evidence of prostate cancer screening, which led to the initiation of the 'The Prostate Cancer Awareness and Initiative for Screening in the European Union' (PRAISE-U) project, which aims to encourage the early detection and diagnosis of PCa through customized and risk-based screening programs.

Surgical repair and analysis of penile fracture complications.

BACKGROUND: The objective of this study is to describe and analyze the experience over a period of 10 years at our center through a retrospective study of a series of diagnosed and treated cases of penile fracture. MATERIAL AND METHODS: From 2005 to 2009 the Urology Department of the Hospital Clínico San Carlos of Madrid carried out a retrospective case study of a total of 15 cases of penile fracture. The diagnosis was reached through physical exploration of the patient aided by a penile ultrasound; the immediate treatment performed on the patients was emergency surgical repair. RESULTS: From the total in the series (n = 15), only 1 case was associated with a complete urethral fracture (6.6%). Surgical repair was performed in all cases; the average hospital stay was 2.6 days (range 1-5), and the most frequent long-term complication was erectile dysfunction in 3 of 15 cases (20%). CONCLUSIONS: A penis fracture diagnosis is mostly clinical; complementary tests, such as ultrasound, are helpful but not definitive. Surgical treatment consists of an incision that allows adequate exposure of the corpora cavernosa and urethra to repair the suspected lesions found upon diagnosis. Ambulatory follow-up is essential to diagnose and treat possible complications.

Long-term outcomes after robotic sacrocolpopexy in pelvic organ prolapse: prospective analysis.

OBJECTIVE: To evaluate the feasibility and long-term outcomes of our initial series of robot-assisted laparoscopic sacrocolpopexy. METHODS: We conducted a prospective analysis of our series of robotic sacrocolpopexy. INCLUSION CRITERIA: patients with grades III and IV cystocele and or other symptomatic pelvic organ prolapse. We performed a transperitoneal four-trocar technique with the Da Vinci robotic system using two polypropylene meshes for fixation to the sacral promontory. The primary outcome was recurrence; secondary outcomes included operating room time, blood loss, conversion to open surgery, complications and length of stay. RESULTS: 31 consecutive procedures were included. Mean patient age was 65.2 (50-81) years. Mean operating room time was 186 (150-230) min. We converted 1 case to laparoscopy (3.2%). There were two major complications (1 acute myocardial infarction and 1 reoperation for excess tension with syncopes), two minor complications (1 wound infection and 1 ileus) and no recurrences at a mean follow-up of 24.5 (16-33) months. CONCLUSIONS: Robotic sacrocolpopexy could possibly improve with experience after overcoming the learning curve. There is no doubt it is a reproducible technique, but its safety and efficacy still need to be proven. Our initial series demonstrated good outcomes and no recurrences at 24.5 months of follow-up.

Key areas in the learning curve for robotic urological surgery: a Spanish multicentre survey.

BACKGROUND: The number of robotic-assisted procedures offered in Spain is rapidly increasing despite a lack of consensus criteria for training and credentialling. OBJECTIVE: This national multicentre study was designed to analyze the different areas of the robotic urological surgery learning curve. MATERIAL AND METHODS: A questionnaire was sent to all 13 urology units in Spain with an active robotics programme requesting information on training and problems encountered. RESULTS: In most centres (n = 11, 84.6%), training programmes were animal-based; cadavers were used at only 2 (15.4%). Proctoring in initial procedures was practiced by 12 groups (92.3%). When initiating the robotics programme, the console was shared at 8 units (61.5%). Prior experience in open and/or laparoscopic surgery was reported by 10 of the groups (76.9%), and experience in open surgery only by 2 (15.4%) or robotic surgery alone by 1 (7.7%). The procedure with which the robotics programme was started in all 13 participating units was radical prostatectomy. The number of cases needed to complete the learning curve for this procedure was 20-25 cases according to 8 (61.5%) surgery teams. CONCLUSIONS: Up until March 26, 2010, 1,692 operations, mostly radical prostatectomies, were conducted using the da Vinci robot in our country.
