Da Vinci vs. Hugo RAS for robot-assisted radical prostatectomy: a prospective comparative single-center study.

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

Organ-Sparing Surgery for Testicular Germ Cell Tumors: A Current Perspective.

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

Critical analysis of a multicentric experience with holmium laser enucleation of the prostate for benign prostatic hyperplasia: outcomes and complications of 10 years of routine clinical practice.

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

Prevention of healthcare-associated infections (HAIs) in a surgical urology ward: observational study-analysis of the problem and strategies for implementation.

PURPOSE: Our purpose is to present the results of our working group, with a view to reduce the incidence and improve the management of healthcare-associated infections (HAIs) in a urology ward. METHODS: The study consists on an observational database designed with the view to analyse the incidence and characteristics of HAIs in Urology. Based on the results obtained, a critical evaluation was carried out and specific measures put in place to reduce HAIs. Finally, the impact and results of the implemented measures were periodically evaluated. RESULTS: The incidence of HAIs in urology decreased from 6.6 to 7.3% in 2012-2014 to 5.4-5.8% in 2016-2018. In patients with immunosuppression the incidence of HAIs decreased from 12.8 to 18% in 2012-2013 to 8.1-10.2% in 2017-2018, in those with a previous urinary infection fell from 13.6 to 4.8%, in those with a urinary catheter prior to admission from 12.6 to 10.8%, and in patients with a nephrostomy tube from 16 to 10.9%. The effect of the protocol also demonstrated a reduction in the percentage of patients with suspicion of HAIs for whom no culture was taken, from 6% in 2012 to zero in 2017 and 2018. Moreover, the implementation of protocols for empirical treatment has reduced the incidence of patients experiencing inadequate empirical antimicrobial therapy from 20 to 8.1%. CONCLUSION: It is essential to monitor the incidence of HAIs, and preventive measures play a useful role in reducing the rate of infection and in optimising their management.

Healthcare-Associated Infections after Lower Urinary Tract Endoscopic Surgery: Analysis of Risk Factors, Associated Microorganisms and Patterns of Antibiotic Resistance.

OBJECTIVES: To review the incidence of healthcare-associated infections/urinary tract infection (UTI), risk factors, microorganisms isolated and antibiotic resistances in patients who underwent lower urinary tract endoscopic surgery (LUTES) in a tertiary care hospital. METHODS: A prospective observational study was carried out including 1,498 patients who undergo LUTES. Patients with and without UTI after surgery were compared. We analysed infection incidence, risk factors, microorganisms isolated and antibiotic resistances. RESULTS: Postoperative UTI incidence was 4.7%. Risk factors found: higher American Society of Anesthesiologists classification (OR 2.82; 95% CI 1.8-4.5; p < 0.00), immunosuppression (OR 2.89; 95% CI 1.2-7.2; p = 0.01), indwelling urinary catheter prior admission (OR 2.6; 95% CI 1.6-4.2; p < 0.00) and postoperative catheterization longer than 2 days (OR 1.74; 95% CI 1.7-4.3; p < 0.00). Transurethral resection of the bladder (TURB) had the highest infection rates (5.5%). Microorganisms isolated were Pseudomonas aeruginosa (23.5%), Escherichia coli (17.6%), Klebsiella pneumoniae and Enterococcus spp (11.8%). Resistance rates for flourquinolones varied between 28 and 80%, and Carbapenem-resistant Enterobacteriaceae rose up 20%. CONCLUSIONS: Low percentage of UTI after endoscopic surgery was registered. TURB was the procedure with highest infection rate. Pseudomonas aeruginosa stands out as the most frequently isolated microorganism. Patient comorbidities, previous urinary catheter and postoperative catheter were identified as risk factors.

Urinary Infections in Patients with Catheters in the Upper Urinary Tract: Microbiological Study.

BACKGROUND: Infections related to catheters in the upper urinary tract (CUUT) are associated with specific characteristics. METHODS: A prospective observational study was carried out from 2012 to 2015 to evaluate infections in patients with CUUT. RESULTS: A total of 209 infections were included (99 with double-J, 81 with nephrostomy, and 29 with internal/external nephroureteral stents). Among nephrostomy tube carriers, the most frequently isolated microorganisms were Pseudomonas and Enterococcus. In those with an internal/external nephroureteral stent, Klebsiella was the most common, and 57.1% were extended-spectrum beta-lactamase-producing Klebsiella. In double-J carriers, Escherichia coli and Enterococcus were the most common microorganisms. Multiple-drug resistance (MDR) microorganisms were isolated in 28.6, 47.1, and 58.3% of patients with double-J, nephrostomy, and internal-external nephroureteral stents. A percutaneous CUUT (p = 0.005) and immunosuppression (p = 0.034) were risk factors for MDR microorganisms. CONCLUSIONS: Non-E. coli bacteria are commonly isolated in patients with CUUT. MDR microorganisms are frequent, mainly in percutaneous approach or immunosuppression.

Extended-Spectrum Beta-Lactamase-Producing Bacteria in a Urology Ward: Epidemiology, Risk Factors and Antimicrobial Susceptibility Patterns.

INTRODUCTION: Our aim was to describe the incidence and risk factors associated with extended-spectrum beta-lactamase (ESBL)-producing Enterobacteriaceae and their resistance rate in a urological ward. MATERIAL AND METHODS: We carried out a prospective observational study from November 2011 to December 2014, reviewing healthcare-associated infections (HAIs) in our department. We evaluated the infections caused by ESBL-producing Enterobacteriaceae. RESULTS: The incidence of HAIs in our urology ward was 6.8%. Enterobacteriaceae including Escherichia coli (24.9%), Klebsiella spp. (12.1%), Enterobacter spp. (5.9%), Morganella spp. (1.5%), Proteus spp. (1.5%), and Citrobacter spp. (1.5%) represented 47.4% of the isolated pathogens. The percentage of ESBL-producing Enterobacteriaceae was 26.4. Risk factors associated with a higher incidence of ESBL-producing bacteria were prior urinary tract infection (UTI; p < 0.001), hypertension (p = 0.042), immunosuppression (p = 0.004), and urinary stone (p = 0.027). The multivariable analysis confirmed prior UTI, immunosuppression and urinary stone as risk factors. ESBL-producing strains showed resistance rates of 85.3% for fluoroquinolones and 11.8% for carbapenems. Moreover, 16.7% of ESBL-Klebsiella were resistant to carbapenems. CONCLUSIONS: ESBL-producing enterobacteria are associated with higher cross resistance to antibiotics such as quinolones. Higher resistance rates are reported in ESBL-producing Klebsiella. Among patients admitted in a urology ward, risk factors for ESBL-producing strains were previous UTI, immunosuppression, and urinary stone.

Da Vinci and Hugo RAS Platforms for robot-assisted partial nephrectomy: a preliminary prospective comparative analysis of the outcomes.

BACKGROUND: Robot-assisted partial nephrectomy (RAPN) has emerged as the preferred approach for T1 renal-cell-carcinoma. As new robotic platforms like Hugo RAS emerge, we seek to understand their potential in achieving similar RAPN outcomes as the established Da Vinci system. METHODS: A prospective single-center comparative study was conducted, and 50 patients selected for RAPN were enrolled (25 Da Vinci Xi; 25 Hugo RAS). The choice of robotic system was based solely on hospital logistics criteria. Surgeries were performed by expert surgeons. Demographic data, tumor characteristics, operative details and postoperative outcomes were collected. SPSS version 22.0 was used for statistical analyses. RESULTS: The average age of patients was 62.52±9.47 years, with no significant differences in median age, sex, and nephrometry scores between groups. Da Vinci group showed a significantly shorter docking time (12.56 vs. 20.08 min; P<0.01), while other intraoperative measures like console time and warm ischemia time were similar. The Hugo RAS group had a shorter renorraphy time (14.33 vs. 18.84 min; P=0.024). Postoperative outcomes and surgical margin positivity showed no significant differences. Each group had one patient (4%) who developed major surgical complications (Clavien IIIa). Trifecta rates were comparable between both groups (Da Vinci 88% vs. Hugo RAS 84%; P=0.93). CONCLUSIONS: Initial findings suggest similar perioperative outcomes for RAPN when using Hugo RAS compared to the Da Vinci system. Further research with long-term follow-up is necessary to evaluate oncological and functional outcomes.

Comparison in Detection Rate of Clinically Significant Prostate Cancer Between Microultrasound-guided Prostate Biopsy (ExactVu) and Multiparametric Resonance Imaging-guided Prostate Biopsy (Koelis System).

OBJECTIVES: To compare the detection rate of clinically significant prostate cancer (csPC) and prostate cancer (PC) and to find out the diagnostic concordance between microultrasound (mUS), a high-resolution imaging system that can identify suspicious prostate lesions and biopsy them in real time, and multiparametric magnetic resonance imaging (mpMRI)-guided prostate fusion biopsies. METHODS: A prospective, multicenter, single-blind, single cohort study was conducted involving 80 patients with clinically suspected PC who underwent concomitant mpMRI-guided fusion prostate biopsy (Koelis System) and mUS-guided biopsy (ExactVu System) RESULTS: The detection rate of csPC was slightly higher for image-guided fusion biopsy (21.25% vs 18.75%), but this difference was not statistically significant (P = .453). There was also no significant difference in overall PC diagnosis (50% vs 51.25%, P = .897). The degree of agreement between the 2 diagnostic techniques for the detection of csPC as assessed by Cohen's Kappa concordance index was satisfactory κ ̂ = 0.676. The degree of International Society of Urological Pathology of targeted biopsies obtained from concordant lesions was also represented by satisfactory concordance with a Kappa index of κ ̂ = 0. 696. CONCLUSION: mUS-guided biopsy is presented as an effective diagnostic method for the diagnosis of csPC compared to image-guided fusion biopsy. No differences are found in the detection rates of csPC and PC between the 2 strategies and satisfactory concordance is found in terms of histopathological findings.

Peyronie's Disease Questionnaire (PDQ): Spanish translation and validation.

The Peyronie's Disease Questionnaire (PDQ) is a 15-question self-reported questionnaire that evaluates the severity and physical and psychosexual issues of Peyronie's disease (PD) symptoms in three scales: "psychological and physical symptoms," "penile pain," and "symptom bother." Previous studies validated the PDQ US version and confirmed its test-retest reliability and responsiveness. The aim is to translate and validate the Spanish version of the PDQ to be used in the clinical practice and in PD research studies in Spain. A non-interventional, observational study with 160 PD patients was conducted. Patients included from four healthcare centers in Spain and completed the PDQ in two study visits separated for a period of 4-7 days from March 2018 to June 2019. Patients received no type of treatment or intervention. Different statistical tests were applied to the data in order to validate the structural and construct of the PDQ, as well as its internal reliability, temporal stability reliability, reliability between observers, and test-retest reliability. Cronbach's alpha over 0.9 showed good internal consistency. We found an ICC agreement of 0.82 (test-retest) for the three scales of the Spanish version of the PDQ, which demonstrates good reliability. When comparing Visit 1 and Visit 2 questionnaires mean scores, the PDQ showed non-significant differences, as expected because no intervention or treatment was administered to the patients between visits. Translation and validation of the PDQ for the Spanish population makes available a valid, useful, and reliable tool to properly evaluate quality of life of men suffering PD.

Treatment of peyronie's disease with combination of clostridium histolyticum collagenase and penile traction therapy: a prospective, multicenter, single-arm study.

The aim of this paper is to analyze our experience with intraplaque administration of collagenase from Clostridium Histolyticum (CCH) together with penile modeling for selected patients with Peyronie's disease (PD). We conducted a prospective, multicenter, single-arm study. Patients were included from October 2015 to August 2019. We carried out the I + E PROTOCOL (IMPRESS + extender). Each cycle involved administration of two injections of CCH separated 24-72 h, up to a maximum of four cycles. 24-48 h after injection patients underwent penile modeling maneuvers with the use of a PTD at home for at least 4 h a day. After each cycle, penile curvature was evaluated by the Kelami test. Mean pretreatment curvature was 57° (30-100). Eighty-seven patients underwent at least a single cycle and were eligible for analysis. Mean number of cycles administered was 2. Final average curvature after treatment, regardless of the number of cycles was 34°, with a mean reduction in curvature of -23.29° (-41%). Across the first three cycles we found statistically significant differences in the means in terms of the degrees of curvature after each cycle (p < 0.05), however this was not maintained in the fourth cycle. Statistical significance was also found when comparing the initial and final curvature after the complete treatment. We can conclude that treatment with CCH for PD is safe and effective. The concomitant use of CCH and PTT may limit the number of treatment cycles necessary to optimize outcomes when compared with CCH alone.

Hepatic sinusoidal obstruction syndrome secondary to intravesical instillation of mitomycin-C.

Hepatic sinusoidal obstruction syndrome (SOS) is a life-threatening complication with high mortality rate. Even if it is more commonly described after hematopoietic stem-cell transplant, hepatic-SOS may occur following the use of certain chemotherapeutic agents. Mitomycin-C has been previously identified as a causal agent when administered intravenously at high doses. We report herein the first case of hepatic-SOS due to intravesical instillation of mitomycin-C, after a traumatic urinary catheterization with significant hematuria. Although this procedure is usually considered safe, without the systemic side effects related to intravenous administration of the drug, clinicians must be aware of its potential risks to facilitate an early diagnosis, avoid a delay in the withdrawal of the causative drug and set up an appropriate therapy as soon as possible.

Factors Influencing Intraoperative Blood Loss in Patients Undergoing Holmium Laser Enucleation of the Prostate (HoLEP) for Benign Prostatic Hyperplasia: A Large Multicenter Analysis.

OBJECTIVE: To assess blood loss during holmium laser enucleation of the prostate (HoLEP) and investigate the factors influencing it. PATIENTS AND METHODS: Analysis of patients with benign prostatic hyperplasia (BPH) treated with HoLEP at 3 centers. Hemoglobin and hematocrit were measured before surgery and hospital discharge. All blood transfusions performed during and after HoLEP were recorded. Blood loss outcomes were analyzed regarding antithrombotic (antiplatelet/anticoagulant) therapies and drug treatments for BPH and other conditions. RESULTS: The analysis included 963 patients with a mean age of 72 years. Mean (range) prostate size was 102 (40-316) g; 28% of patients were receiving antiplatelets and 11% anticoagulants. Mean (range) prostate-specific antigen was 6.0 (0.3-43.5) ng/dL. Mean (range) operation time was 77 (28-178) minutes. Bladder calculi were found in 54 (5.6%) patients; all of them were successfully treated with cystolitholapaxy. Forty-eight (5%) patients required blood transfusion during or immediately after the HoLEP procedure. Overall, mean (SD) hemoglobin decreased from 14.6 (1.5) g/dL to 12.3 (2.1) g/dL (P <.001), and mean (SD) hematocrit decreased from 44.3% (4.7) to 37.7% (6.5) (P <.001). Neither hemoglobin nor hematocrit decreases were significantly different between patients receiving and not receiving antithrombotic therapy or BPH therapy. CONCLUSION: HoLEP is safe and has no remarkable impact on blood loss. Patients at high risk, such as those receiving antithrombotic therapy, had the same outcome than the rest regarding blood loss, although showed a higher transfusion rate. Operating time may influence hemoglobin decrease; therefore, it should be considered in patients with higher risk of bleeding.

[Training program on medical urology: Future perspectives.] / Programa formativo en urología médica: perspectivas para el futuro.

Urology is defined as the medical-surgical specialty that includes the study, diagnosis and treatment of medical conditions of the urinary system. It is well specified by the National Commission of Specialties that we must know the medical pathology that concerns us. However, on occasions, resident training focuses on the surgical field and oncological pathology, which, although one of the main pillars of the specialty, is usually to the detriment of training in medical and functional pathology. We conducted a survey of residents in the fourth year of Urology in Spain, where we asked about the quality of training in Andrology and Functional Urology. The average rotation time is 3.5 months in each unit. Only 20% consider that their training is satisfactory and sufficient in Andrology. Seventy-five percent of residents surveyed believe that their training in Functional Urology is acceptable or sufficient, both medical and surgical. There are numerous fields of action to improve the training of residents and young urologists in this country in the management of urological medical pathology. The future is open, and it is in our hand to set up a training for urology residents within excellence and to be recognized both nationally and internationally as one of the great pillars of Spanish Urology. In this chapter we will analyze the current situation in the training of Spanish Urology Residents in urological medical pathology, and we will focus on training in functional urology and andrology.

[Maximal androgen deprivation with abiraterone acetate in hormone sensitive prostate cancer.] / Supresión androgénica máxima con acetato de abiraterona en cáncer de próstata hormonosensible.

OBJECTIVES: The treatment of metastatic prostate cancer has remained unchanged for more than 70 years, based on androgen deprivation therapy (ADT). In 2015, following the CHAARTED and STAMPEDE trials, it was established that the addition of 6 cycles of docetaxel to ADT was associated with significantly increased survival. In June 2017, the LATITUDE trial and the G arm of the STAMPEDE trial showed that the addition of Abiraterone with Prednisone (5 mg/day) to ADT was also associated with a significant increase in survival in metastatic patients. The present study analyzes these two trials. RESULTS: LATITUDE demonstrated a 38% reduction in the risk of death (HR=0.62, 95% CI, 0.61-0.76) in almost all sub-groups. Risk reduction for radiological progression was 53% (HR=0.47, 95% CI 0.39-0.55). Secondary objectives such as prostate specific antigen progression, time to chemotherapy or a new skeletal event are also significantly delayed. STAMPEDE also showed that the combination of Abiraterone and Prednisone is associated with a 37% increase in survival (HR=0.63, 95% CI, 0.52- 0.76, p<0.001) in metastatic patients, but not in nonmetastatic patients. Progression-free survival was greatly improved in this arm (HR=0.29, 95% CI 0.25-0.34, p<0.001). The side effects reported show the known pattern of mineral corticosteroid excess with increased blood pressure, hypokalemia, and of liver enzymes elevation. CONCLUSIONS: The indirect comparison of docetaxel and abiraterone studies confirms that both populations and results are comparable. Two comparative indirect metanalysis (>6000 patients) gave marginal superiority to abiraterone. In favor of abiraterone we have that it is an oral, comfortable medication with a good tolerance profile and side effects that are easy to manage, useful in patients who are old and fragile, in whom chemotherapy may not be indicated; the downsides are prolonged exposure to the drug and its current price. Future trials, currently in progress, will determine the ideal patient profile, or a potential association of both therapies.

Sexual Satisfaction: An Opportunity to Explore Overall Health in Men.

OBJECTIVE: To evaluate the use of sexual dissatisfaction as a marker of poor overall health. Secondary objectives were to assess the effect of age on this measure and the utility of the Brief Sexual Symptom Checklist (BSSC) for general practitioners (GPs) and patients. METHODS: This is a multicenter, cross-sectional study conducted in Spain among men aged ≥50 years presenting with mood disorders or cardiovascular comorbidities (hypertension, dyslipidemia, or diabetes) visiting a GP for any reason. A group of men without these comorbidities were also analyzed. The main outcome measures were prevalence of sexual dissatisfaction, based on the comorbidities analyzed (type, number, or their absence) and problems with sexual function in dissatisfied men (overall and in men aged < 60 or ≥60 years). RESULTS: Seven hundred eighteen men aged 61.7 ± 7.1 years who presented the analyzed comorbidities participated, 69.8% of whom were sexually dissatisfied. Men without comorbidities (n = 144) were younger and had lower prevalence of sexual dissatisfaction (54.2%; P = .001). Sexual dissatisfaction increased with age. Having these comorbidities (especially mood disorders) significantly increased the likelihood of sexual dissatisfaction after adjusting for age. Erection problems and lack of interest in sex were the most reported problems, independent of the presence of comorbidities. Differences in the prevalence of these problems were found in men with and without comorbidities after splitting the population into 2 age groups. GPs and dissatisfied patients found the BSSC useful and easy to use. CONCLUSION: Assessment of sexual satisfaction and related sexual problems using the BSSC could help in approaching men's overall health. Further research is needed.

Prospective study analyzing risk factors and characteristics of healthcare-associated infections in a Urology ward.

PURPOSE: Healthcare-associated infections (HAIs) in urological patients have special features due to specific risk factors. Our objective was to evaluate the characteristics and risk factors for HAIs in patients hospitalized in a Urology ward. MATERIALS AND METHODS: We evaluated prospectively, from 2012 to 2015, the incidence, types and risk factor for HAIs, microbiological and resistance patterns. RESULTS: The incidence of HAIs was 6.3%. The most common types were urinary infections (70.5%) and surgical site infections (22.1%). Univariate analysis showed an increased risk of HAIs among patients with American Society of Anesthesiologists physical status classification system III-IV (odds ratio [OR], 1.39; p<0.001), immunosuppression (OR, 1.80; p=0.013), previous urinary infection (OR, 4.46; p<0,001), and urinary catheter before admission (OR, 1.74; p<0.001). The surgical procedures with the highest incidence of HAIs were radical cystectomy (54.2%) and renal surgery (8.7%). The most frequently isolated microorganisms were Escherichia coli (25.1%), Enterococcus spp. (17.5%), Klebsiella spp. (13.5%) and Pseudomonas aeruginosa (12.3%). Enterococcus sp was the most common microorganism after radical cystectomy and in surgical site infections, E. coli showed resistance rates of 53.5% for fluoroquinolones, 9.3% for amikacin. The percentage of extended-spectrum betalactamase producing E. coli was 24.7%. Klebsiella spp. showed resistance rates of 47.8% for fluoroquinolones, 7.1% for amikacin and 4.3% for carbapenems. Enterococcus spp showed resistance rates of 1.7% for vancomycin and; P. aeruginosa of 33.3% for carbapenems and 26.2% for amikacin. CONCLUSIONS: Comorbidities, previous urinary infections, and urinary catheter are risk factors for HAIs. The microorganisms most commonly isolated were E. coli, Enterococcus and P. aeruginosa. Prospective monitoring may decrease the incidence of infections.

Supresión androgénica máxima con acetato de abiraterona en cáncer de próstata hormonosensible / Maximal androgen deprivation with abiraterone acetate in hormone sensitive prostate cancer

OBJETIVO: El tratamiento del cáncer de próstata (CP) metastático ha permanecido inalterado durante más de 70 años fundamentado en la deprivación androgénica (DA). En 2015, a raíz de los estudios CHAARTED y STAMPEDE se estableció que la adición de 6 ciclos de docetaxel a la DA se asociaba significativamente con incremento de la supervivencia. En junio de 2017 los estudios LATITUDE y el brazo G del STAMPEDE demuestran que la adición de Abiraterona junto con Prednisona (5 mg/día) a DA se asocia también a un incremento significativo de supervivencia en los pacientes metastáticos. El presente trabajo analiza estos dos estudios. RESULTADOS: LATITUDE demostró una reducción relativa del riesgo de muerte del 38% (HR=0,62, 95% IC, 0,61-0,76) patente en la práctica totalidad de subgrupos. La reducción del riesgo relativo de progresión radiológica fue del 53 % (HR=0,47,IC 95% 0,39-0,55). Los objetivos secundarios como progresión de PSA, tiempo a quimioterapia o a nuevo evento esquelético también son significativamente retrasados. STAMPEDE también demuestra que la combinación con Abiraterona+prednisolona se asocia a un incremento relativo de SV del 37% (HR=0,63;95% IC, 0,52-0,76; p < 0,001) en pacientes M1, no así en los M0. La supervivencia libre de progresión fue muy mejorada en este brazo (HR=0,29;95% IC 0,25-0,34, p < 0,001). Los efectos secundarios referidos muestran el patrón conocido de exceso mineralcorticoide con incremento de HTA, hipokaliemia y elevación de enzimas hepáticas. CONCLUSIONES: La comparación indirecta de los trabajos de docetaxel y abiraterona confirma que tanto poblaciones, como resultados, son superponibles. Dos meta-análisis indirectos comparativos (>6000 pacientes) otorgan beneficio marginal a abiraterona. A favor de Abiraterona juega el ser una medicación oral, cómoda, con buen perfil de tolerancia y efectos secundarios de fácil manejo, útil en pacientes con frecuencia añosos y frágiles en los que la QT pudiera no estar indicada, aún a costa de una exposición al fármaco es más prolongada y de su actual precio. Futuros ensayos, en curso, determinará el perfil de pacientes idóneo, su posicionamiento en el tiempo o una potencial asociación de ambos

OBJECTIVES: Prostate cancer is linked to bone disease by two different entities. On one hand, androgen deprivation therapy (ADT) usually causes osteoporosis, on the other a great number of patients with advanced prostate cancer will present bone bicametastases, that condition not only their vital prognosis but also an important quality of life deterioration. METHODS: We performed a bibliographic review on both the physiology and therapy of osteoporosis secondary to ADT and bone metastasis in prostatic neoplasias. RESULTS: Osteoporosis: Long term ADT is associated with osteopenia/osteoporosis in 80% of the patients, with a 5-20% incidence of osteoporotic fractures. We should monitor bone mineral density before starting ADT therapy and during treatment. Treatment is based on risk factors reduction, regular physical exercise, calcium and vitamin D supplements, and drugs such as biphosphonates or denosumab. Bone metastasis: Currently, both zolendronic acid and denosumab have approval for the prevention of skeletal events in patients with castration resistant prostate cancer (CPRC). Although the last one seems to be more effective, it is associated with a higher risk of hypocalcemia and jaw osteonecrosis so that the choice of drug must be individualized in every patient. The duration of treatment is not clear. Currently, the indication for the use of this drugs in earlier phases of advanced disease is not approved. CONCLUSIONS: Comprehensive management of the patient with advanced prostate cancer should include the study and treatment of osteoporosis and bone metastases. Currently, very effective therapies are available for both entities

Programa formativo en urología médica: perspectivas para el futuro / Training program on medical urology: Future perspectives

La Urología está definida como la especialidad médico-quirúrgica que engloba el estudio, diagnóstico y tratamiento de las afecciones médicas del aparato urinario. Queda bien especificado por la Comisión Nacional de Especialidades que debemos conocer la patología médica que nos compete. Sin embargo, en ocasiones, la formación de los residentes se centra en el ámbito quirúrgico y la patología oncológica, que, si bien es uno de los grandes pilares de la especialidad, suele ser en detrimento de la formación en patología médica y funcional. Hemos realizado una encuesta a residentes de cuarto año de Urología de España, en la que preguntamos sobre la calidad de la formación en Andrología y Urología Funcional. La media de tiempo de rotación es de 3,5 meses en cada unidad. Solo un 20% considera que su formación es satisfactoria y suficiente en Andrología. El 75% de los residentes encuestados considera que su formación en Urología Funcional es aceptable o suficiente, tanto a nivel médico como quirúrgico. Existen numerosos campos de actuación para la mejora de la formación de los residentes y jóvenes urólogos de este país en el manejo de la patología médica urológica. El futuro está abierto, y está en nuestra mano configurar una formación para los residentes de urología dentro de la excelencia y que sea reconocida tanto a nivel nacional como internacional como uno de los grandes pilares de la Urología española. En este capítulo analizaremos la situación actual en la formación de los Residentes de Urología españoles en la patología médica urológica, y nos vamos a centrar en la formación en urología funcional y andrología (AU)

Urology is defined as the medical-surgical specialty that includes the study, diagnosis and treatment of medical conditions of the urinary system. It is well specified by the National Commission of Specialties that we must know the medical pathology that concerns us. However, on occasions, resident training focuses on the surgical field and oncological pathology, which, although one of the main pillars of the specialty, is usually to the detriment of training in medical and functional pathology. We conducted a survey of residents in the fourth year of Urology in Spain, where we asked about the quality of training in Andrology and Functional Urology. The average rotation time is 3.5 months in each unit. Only 20% consider that their training is satisfactory and sufficient in Andrology. Seventy-five percent of residents surveyed believe that their training in Functional Urology is acceptable or sufficient, both medical and surgical. There are numerous fields of action to improve the training of residents and young urologists in this country in the management of urological medical pathology. The future is open, and it is in our hand to set up a training for urology residents within excellence and to be recognized both nationally and internationally as one of the great pillars of Spanish Urology. In this chapter we will analyze the current situation in the training of Spanish Urology Residents in urological medical pathology, and we will focus on training in functional urology and andrology (AU)
