RESUMEN

OBJECTIVES: To determine the oncological impact and adverse events of performing simultaneous transurethral resection of bladder tumour (TURB) and transurethral resection of the prostate (TURP), as evidence on the outcomes of simultaneous TURB for bladder cancer and TURP for obstructive benign prostatic hyperplasia is limited and contradictory. PATIENTS AND METHODS: Patients from 12 European hospitals treated with either TURB alone or simultaneous TURB and TURP (TURB+TURP) were retrospectively analysed. A propensity score matching (PSM) 1:1 was performed with patients from the TURB+TURP group matched to TURB-alone patients. Associations between surgery approach with recurrence-free (RFS) and progression-free (PFS) survivals were assessed in Cox regression models before and after PSM. We performed a subgroup analysis in patients with risk factors for recurrence (multifocality and/or tumour size >3 cm). RESULTS: A total of 762 men were included, among whom, 76% (581) underwent a TURB alone and 24% (181) a TURB+TURP. There was no difference in terms of tumour characteristics between the groups. We observed comparable length of stay as well as complication rates including major complications (Clavien-Dindo Grade ≥III) for the TURB-alone vs TURB+TURP groups, while the latest led to longer operative time (P < 0.001). During a median follow-up of 44 months, there were more recurrences in the TURB-alone (47%) compared to the TURB+TURP group (28%; P < 0.001). Interestingly, there were more recurrences at the bladder neck/prostatic fossa in the TURB-alone group (55% vs 3%, P < 0.001). TURB+TURP procedures were associated with improved RFS (hazard ratio [HR] 0.39, 95% confidence interval [CI] 0.29-0.53; P < 0.001), but not PFS (HR 1.63, 95% CI 0.90-2.98; P = 0.11). Within the PSM cohort of 254 patients, the simultaneous TURB+TURP was still associated with improved RFS (HR 0.33, 95% CI 0.22-0.49; P < 0.001). This was also true in the subgroup of 380 patients with recurrence risk factors (HR 0.41, 95% CI 0.28-0.62; P < 0.001). CONCLUSION: In our contemporary cohort, simultaneous TURB and TURP seems to be an oncologically safe option that may, even, improve RFS by potentially preventing disease recurrence at the bladder neck and in the prostatic fossa.

RESUMEN

BACKGROUND AND OBJECTIVES: Age might influence the choice of surgical approach, type of urinary diversion (UD) and lymph node dissection (LND) in patients candidate to radical cystectomy (RC) for urothelial bladder cancer (UBC). Similarly, age may enhance surgical morbidity and worsen perioperative outcomes. We tested the impact of age (octogenarian vs. younger patients) on surgical decision making and peri- and postoperative outcomes of RC. METHODS: Non-metastatic muscle-invasive UBC patients treated with RC at 18 high-volume European institutions between 2006 and 2021 were identified and stratified according to age (≥80 vs. <80 years). Intraoperative Complications Assessment and Reporting with Universal Standards and European Association of Urology guidelines recommendations were accomplished in collection and reporting of, respectively, intraoperative and postoperative complications. Multivariable logistic regression models (MVA) tested the impact of age on outcomes of interest. Sensitivity analyses after 1:3 propensity score matching were performed. RESULTS: Of 1955 overall patients, 251 (13%) were ≥80-year-old. Minimally invasive RC was performed in 18% and 40% of octogenarian and younger patients, respectively (p < 0.001). UD without bowel manipulation (ureterocutaneostomy, UCS) was performed in 31% and 7% of octogenarian and younger patients (p < 0.001). LND was delivered to 81% and 93% of octogenarian and younger patients (p < 0.001). At MVA, age ≥80 years independently predicted open approach (odds ratio [OR]: 1.55), UCS (OR: 3.70), and omission of LND (OR: 0.41; all p ≤ 0.02). Compared to their younger counterparts, octogenarian patients experienced higher rates of intraoperative (8% vs. 4%, p = 0.04) but not of postoperative complications (64% vs. 61%, p = 0.07). At MVA, age ≥80 years was not an independent predictor of length of stay, intraoperative or postoperative transfusions and complications, and readmissions (all p values >0.1). These results were replicated in sensitivity analyses. CONCLUSIONS: Age ≥80 years does not independently portend worse surgical outcomes for RC. However, octogenarians are unreasonably more likely to receive open approach and UCS diversion, and less likely to undergo LND.

RESUMEN

BACKGROUND: The evidence of prognostic factors and individualized surveillance strategies for upper tract urothelial carcinoma are still weak. OBJECTIVES: To evaluate whether the history of previous malignancy (HPM) affects the oncological outcomes of upper tract urothelial carcinoma (UTUC). METHODS: The CROES-UTUC registry is an international, observational, multicenter cohort study on patients diagnosed with UTUC. Patient and disease characteristics from 2380 patients with UTUC were collected. The primary outcome of this study was recurrence-free survival. Kaplan-Meier and multivariate Cox regression analyses were performed by stratifying patients according to their HPM. RESULTS: A total of 996 patients were included in this study. With a median recurrence-free survival time of 7.2 months and a median follow-up time of 9.2 months, 19.5% of patients had disease recurrence. The recurrence-free survival rate in the HPM group was 75.7%, which was significantly lower than non-HPM group (82.7%, P = 0.012). Kaplan-Meier analyses also showed that HPM could increase the risk of upper tract recurrence (P = 0.048). Furthermore, patients with a history of non-urothelial cancers had a higher risk of intravesical recurrence (P = 0.003), and patients with a history of urothelial cancers had a higher risk of upper tract recurrence (P = 0.015). Upon multivariate Cox regression analysis, the history of non-urothelial cancer was a risk factor for intravesical recurrence (P = 0.004), and the history of urothelial cancer was a risk factor for upper tract recurrence (P = 0.006). CONCLUSION: Both previous non-urothelial and urothelial malignancy could increase the risk of tumor recurrence. But different cancer types may increase different sites' risk of tumor recurrence for patients with UTUC. According to present study, more personalized follow-up plans and active treatment strategies should be considered for UTUC patients.

RESUMEN

OBJECTIVE: To determine whether use of neoadjuvant chemotherapy (NAC) is associated with a higher risk of post-operative complications following radical cystectomy (RC) for bladder cancer (BCa). MATERIALS AND METHODS: We retrospectively reviewed records of patients undergoing RC for non-metastatic urothelial BCa at 13 tertiary care centres from 2007-2019. Patients who received NAC ('NAC + RC' group) were compared with those who underwent upfront RC ('RC alone' group) for intra-operative variables, incidence of post-operative complications as per the Clavien-Dindo classification (CDC) and rates of re-admission and re-intervention. Multivariable logistic regression analysis was performed to determine predictors of CDC overall and CDC major (grade III-V) complications. We also analysed the trend of NAC utilization over the study period. RESULTS: Of the 3113 patients included, 968 (31.1%) received NAC while the remaining 2145 (68.9%) underwent upfront RC for BCa. There was no significant difference between the NAC + RC and RC alone groups with regards to 30-day CDC overall (53.2% vs 54.6%, p = 0.4) and CDC major (15.5% vs 16.5%, p = 0.6) complications. The two groups were comparable for the rate of surgical re-intervention (14.6% in each group) and re-hospitalization (19.6% in NAC + RC vs 17.9% in RC alone, p = 0.2%) at 90 days. On multivariable regression analysis, NAC use was not found to be a significant predictor of 90-day CDC overall (OR 1.02, CI 0.87-1.19, p = 0.7) and CDC major (OR 1.05, CI 0.87-1.26, p = 0.6) complications. We also observed that the rate of NAC utilization increased significantly (p < 0.001) from 11.1% in 2007 to 41.2% in 2019, reaching a maximum of 48.3% in 2018. CONCLUSION: This large multicentre analysis with a substantial rate of NAC utilization showed that NAC use does not lead to an increased risk of post-operative complications following RC for BCa. This calls for increasing NAC use to allow patients to avail of its proven oncologic benefit.

RESUMEN

PURPOSE: Presently, major guidelines do not provide specific recommendations on oncologic surveillance for patients who harbor variant histology (VH) bladder cancer (BCa) at radical cystectomy. We aimed to create a personalized followup scheme that dynamically weighs other cause mortality (OCM) vs the risk of recurrence for VH BCa, and to compare it with a similar one for pure urothelial carcinoma (pUC). MATERIALS AND METHODS: Within a multi-institutional registry, 528 and 1,894 patients with VH BCa and pUC, respectively, were identified. The Weibull regression was used to detect the time points after which the risk of OCM exceeded the risk of recurrence during followup. The risk of OCM over time was stratified based on age and comorbidities, and the risk of recurrence on pathological stage and recurrence site. RESULTS: Individuals with VH had a higher risk of recurrence (recurrence-free survival 30% vs 51% at 10 years, p <0.001) and shorter median time to recurrence (88 vs 123 months, p <0.01) relative to pUC. Among VH, micropapillary variant conferred the greatest risk of recurrence on the abdomen and lungs, and mixed variants carried the greatest risk of metastasizing to bones and other sites compared to pUC. Overall, surveillance should be continued for a longer time for individuals with VH BCa. Notably, patients younger than 60 years with VH and pT0/Ta/T1/N0 at radical cystectomy should continue oncologic surveillance after 10 years vs 6.5 years for pUC individuals. CONCLUSIONS: VH BCa is associated with greater recurrence risk than pUC. A followup scheme that is valid for pUC should not be applied to individuals with VH. Herein, we present a personalized approach for surveillance that may allow an improved shared decision.

RESUMEN

PURPOSE: To determine how members of the Société Internationale d'Urologie (SIU) are continuing their education in the time of COVID-19. METHODS: A survey was disseminated amongst SIU members worldwide by email. Results were analyzed to examine the influence of age, practice region and settings on continuing medical education (CME) of the respondents. RESULTS: In total, 2494 respondents completed the survey. Internet searching was the most common method of CME (76%; all ps < 0.001), followed by searching journals and textbook including the online versions (62%; all ps < 0.001). Overall, 6% of the respondents reported no time/interest for CME during the pandemic. Although most urologists report using only one platform for their CME (26.6%), the majority reported using ≥ 2 platforms, with approximately 10% of the respondents using up to 5 different platforms. Urologists < 40 years old were more likely to use online literature (69%), podcasts/AV media (38%), online CME courses/webinars (40%), and social media (39%). There were regional variations in the CME modality used but no significant difference in the number of methods by region. There was no significant difference in responses between urologists in academic/public hospitals or private practice. CONCLUSION: During COVID-19, urologists have used web-based learning for their CME. Internet learning and literature were the top frequently cited learning methods. Younger urologists are more likely to use all forms of digital learning methods, while older urologists prefer fewer methods.

RESUMEN

PURPOSE: To assess the impact of perioperative chemotherapy on survival in cN+ BCa patients and analyze it according to the pN status. METHODS: A retrospective analysis was conducted on 639 BCa patients with cTanyN1-3M0 BCa treated with radical cystectomy (RC) and bilateral lymph node dissection (LND) with or without perioperative chemotherapy in ten tertiary referral centers from 1990 to 2017. Selected cN+ patients received induction chemotherapy (IC), whereas adjuvant chemotherapy (ACT) was delivered to selected pN+ patients. Univariable and multivariable Cox regression analyses were used to predict overall mortality (OM) after surgery, adjusting for clinicopathological confounders. Kaplan-Meier analyses assessed OM according to the treatment modality. RESULTS: Overall, 356 (56%) patients were treated with surgery alone, 155 (24%) with IC followed by surgery, and 128 (20%) with ACT following surgery. Over a median follow-up of 25 months, 316 deaths were recorded. At univariable analysis, patients treated with IC and surgery had lower OM both considering cN+ [hazard ratio (HR) 0.65, 95% confidence interval (CI) 0.49-0.87, p = 0.004] and cN+pN- patients (HR 0.61, 95% CI 0.37-0.99, p = 0.05) compared to those treated with surgery alone. cN+pN+ patients treated with ACT experienced lower OM compared to those treated with IC or surgery alone at multivariable analysis (HR 0.40, 95% CI 0.22-0.74, p = 0.003). CONCLUSION: Patients with cTany cN+ cM0 BCa benefit more in terms of OS when treated with IC followed by RC + LND compared to RC + LND alone, regardless of LNMs at final histopathology examination. More data are needed to assess the role of ACT in the management of cN+ patients.

RESUMEN

PURPOSE: This study was carried out to assess whether a prolonged time between primary transurethral resection of non-muscle-invasive bladder cancer (TURB) and implementation of bacillus Calmette-Guerin (BCG) immunotherapy (time to BCG; TTBCG) is associated with adverse oncological survival in patients with T1 high-grade (HG) non-muscle-invasive bladder cancer (NMIBC). MATERIALS AND METHODS: Data on 429 patients from 13 tertiary care centers with primary T1HG NMIBC treated with reTURB and maintenance BCG between 2001 and 2019 were retrospectively reviewed. Change-point regression was applied following Muggeo's approach. The population was divided into subgroups according to TTBCG, whereas the recurrence-free survival (RFS) and progression-free survival (PFS) were estimated with log-rank tests. Additionally, Cox regression analyses were performed. Due to differences in baseline patient characteristics, propensity-score-matched analysis (PSM) and inverse-probability weighting (IPW) were implemented. RESULTS: The median TTBCG was 95 days (interquartile range (IQR): 71-127). The change-point regression analysis revealed a gradually increasing risk of recurrence with growing TTBCG. The risk of tumor progression gradually increased until a TTBCG of approximately 18 weeks. When the study population was divided into two subgroups (time intervals: ≤ 101 and > 101 days), statistically significant differences were found for both RFS (p = 0.029) and PFS (p = 0.005). Furthermore, in patients with a viable tumor at reTURB, there were no differences in RFS and PFS. After both PSM and IPW, statistically significant differences were found for both RFS and PFS, with worse results for longer TTBCG. CONCLUSION: This study shows that delaying BCG immunotherapy after TURB of T1HG NMIBC is associated with an increased risk of tumor recurrence and progression.

RESUMEN

OBJECTIVES: To determine the well-being of urologists worldwide during the coronavirus disease 2019 pandemic, and whether they have adequate personal protective equipment knowledge and supplies appropriate to their clinical setting. METHODS: Urologists worldwide completed a Société Internationale d'Urologie online survey from 16 April 2020 until 1 May 2020. Analysis was carried out to evaluate their knowledge about protecting themselves and others in the workplace, including their confidence in their ability to remain safe at work, and any regional differences. RESULTS: There were 3488 respondents from 109 countries. Urologists who stated they were moderately comfortable that their work environment offers good protection against coronavirus disease 2019 showed a total mean satisfaction level of 5.99 (on a "0 = not at all" to "10 = very" scale). A large majority (86.33%) were confident about protecting themselves from coronavirus disease 2019 at work. However, only about one-third reported their institution provided the required personal protective equipment (35.78%), and nearly half indicated their hospital has or had limited personal protective equipment availability (48.08%). Worldwide, a large majority of respondents answered affirmatively for testing the healthcare team (83.09%). Approximately half of the respondents (52.85%) across all regions indicated that all surgical team members face an equal risk of contracting coronavirus disease 2019 (52.85%). Nearly one-third of respondents reported that they had experienced social avoidance (28.97%). CONCLUSIONS: Our results show that urologists lack up-to-date knowledge of preferred protocols for personal protective equipment selection and use, social distancing, and coronavirus disease 2019 testing. These data can provide insights into functional domains from which other specialties could also benefit.

RESUMEN

INTRODUCTION: We aimed to evaluate adherence to the EAU guidelines (GL) on penile cancer (PC) with regard to primary surgical treatment and management of lymph nodes and to estimate the influence of adherence to GL on clinical outcome. MATERIALS AND METHODS: This is a retrospective multicenter study (PEnile Cancer ADherence study, PECAD Study) on PC patients treated at 12 European and American centers between 2010 and 2016. Adherence to the EAU GL on the surgical management of the primary penile tumor and lymphadenectomy was evaluated. Descriptive analyses were performed, and survival curves were estimated. RESULTS: Data on 425 patients were considered for the analysis. The EAU GL on surgical treatment of the primary tumor and lymphadenectomy were respected in 74.8% and 73.7% of cases, respectively. Survival analysis showed that adherence to the GL on primary penile surgery was significantly associated with a good overall survival [adjusted HR 0.40 (95% CI 0.20-0.83, p value = 0.014)]. Also, the adherence to the GL on lymphadenectomy was statistically significantly associated with overall survival [adjusted HR 0.48 (95% CI 0.24-0.96, p value = 0.038)]. Limited follow-up and retrospective design represent limitations of this study. CONCLUSIONS: Our findings suggest that there is a good adherence to the EAU GL on PC. However, this should be further reinforced, endorsed and encouraged as it might translate into better clinical outcomes for PC patients.

RESUMEN

Castleman's disease (CD) is an uncommon type of lymphoproliferative disorder. Its etiology and prevalence are unclear. The retroperitoneum is a very rare site for presentation of the unicentric variant, where it mimics malignant tumors. A 59-year-old man is referred to the urology outpatient clinic for the study of microhematuria found in a routine analysis. CT scan of the abdomen identified a solid, circumscribed mass, measuring 28 × 30 × 31 mm in the left para-aortic zone, with homogeneous contrast enhancement. Excisional surgery and regional lymphadenectomy were performed via laparoscopy. Postoperative course concurred without incidences. Histological diagnosis confirmed unicentric CD, hyaline-vascular type. CD is a rare entity, and the unicentric type presents as an asymptomatic mass. Retroperitoneum is a rare localization, where initial imaging diagnosis is unclear and surgical resection is the preferred treatment.

RESUMEN

PURPOSE: To describe the perioperative and oncology outcomes in a series of laparoscopic or robotic partial nephrectomies (PN) for renal tumors treated in diverse institutions of Hispanic America from the beginning of their minimally invasive (MI) PN experience through December 2014. METHODS: Seventeen institutions participated in the CAU generated a MI PN database. We estimated proportions, medians, 95 % confidence intervals, Kaplan-Meier curves, multivariate logistic and Cox regression analyses. Clavien-Dindo classification was used. RESULTS: We evaluated 1501 laparoscopic (98 %) or robotic (2 %) PNs. Median age: 58 years. Median surgical time, warm ischemia and intraoperative bleeding were 150, 20 min and 200 cc. 81 % of the lesions were malignant, with clear cell histology being 65 % of the total. Median maximum tumor diameter is 2.7 cm, positive margin is 8.2 %, and median hospitalization is 3 days. One or more postoperative complication was recorded in 19.8 % of the patients: Clavien 1: 5.6 %; Clavien 2: 8.4 %; Clavien 3A: 1.5 %; Clavien 3B: 3.2 %; Clavien 4A: 1 %; Clavien 4B: 0.1 %; Clavien 5: 0 %. Bleeding was the main cause of a reoperation (5.5 %), conversion to radical nephrectomy (3 %) or open partial nephrectomy (6 %). Transfusion rate is 10 %. In multivariate analysis, RENAL nephrometry score was the only variable associated with complications (OR 1.1; 95 % CI 1.02-1.2; p = 0.02). Nineteen patients presented disease progression or died of disease in a median follow-up of 1.37 years. The 5-year progression or kidney cancer mortality-free rate was 94 % (95 % CI 90, 97). Positive margins (HR 4.98; 95 % CI 1.3-19; p = 0.02) and females (HR 5.6; 95 % CI 1.7-19; p = 0.005) were associated with disease progression or kidney cancer mortality after adjusting for maximum tumor diameter. CONCLUSION: Laparoscopic PN in these centers of Hispanic America seem to have acceptable perioperative complications and short-term oncologic outcomes.

RESUMEN

PURPOSE: This is a prospective multicentric comparative study evaluating the performance of XenX-a new dual-purpose device for the prevention of stone fragments migration during ureteroscopic lithotripsy (URS). METHODS: Between March 2014 and January 2015, 41 patients undertaking URS + XenX were matched with 41 patients undergoing standard URS. Patients included had unilateral ureteric stone(s) of 0.5-1.5 cm in maximum size. Demographics, complication rates and surgical outcomes were recorded for comparison. A Likert-like 5-grade scoring system was used for surgeons' evaluation of XenX properties. Cost analysis was performed by comparing weighted mean costs of the relevant procedures. RESULTS: Patients' characteristics between the two groups were comparable. Lasering time was longer for XenX group (13.59 vs. 5.17 min; p = 0.0001) whilst use of basket and need of JJ stent insertion was more frequent in control group (19.5 vs. 97.6 %; p = 0.0001 and 22 vs. 35 %; p = 0.001, respectively). Intra-operative SFR was significantly higher for XenX group (100 vs. 85.4 %; p = 0.0001), but not at 4-week follow-up, after ancillary procedures were needed in 17.1 % of the control group. Surgeons' evaluations for XenX were suboptimal for "Ease of Basketing" (2/5) and "Advancement of double J stent" (3/5). The use of XenX increased costs of procedures, but spared the costs associated to ancillary procedures and stent removals. CONCLUSIONS: XenX confirmed to be a safe and effective device especially for the treatment of upper ureteric tract stones; moreover, XenX may reduce the risk for the need of auxiliary procedures and for the insertion of a JJ stent.

RESUMEN

Posterior urethral injuries typically arise in the context of a pelvic fracture.The correct and appropriate initial treatment of associated urethral rupture is critical to the proper healing of the injury. In this paper, we provide a comprehensive review of the literature with special emphasis on the various treatments available: open or endoscopic primary realignment, immediate or delayed urethroplasty after suprapubic cystostomy, and delayed optical urethrotomy.

RESUMEN

INTRODUCTION: Systemic therapy of patients with metastatic renal cell carcinoma (mRCC) has improved in the past years, with the advent of new immunotherapy-based combinations as a standard treatment option for first-line therapy. Nevertheless, particularly in good-risk patients by IMDC criteria, tyrosine-kinase inhibitors (TKI) may remain as an option for some patients. We reviewed our experience with TKI as first-line therapy for mRCC patients, trying to identify subgroups of patients that may still benefit from this strategy. MATERIAL AND METHODS: All patients with mRCC treated with first-line TKI, and adequate follow-up, in University Hospital La Paz (Madrid, Spain) between 2007 and 2020 were analyzed. Patients treated inside a clinical trial were excluded from this analysis. RESULTS: A total of 90 patients treated with first-line TKI were included. Regarding IMDC criteria, 33 patients (36.7%) were good-risk, 41 patients (45.5%) intermediate-risk, and 16 patients (17.8%) poor-risk. With a median follow-up of 49 months, the median overall survival (OS) for good, intermediate, and poor-risk patients was 54, 24, and 16 months (p = 0.004). When intermediate-risk was divided into patients with 1 or 2 risk factors, differences in OS were also statistically significant: patients with 1 risk factor had a median OS of 33 months, while patients with 2 risk factors had a median OS of 16 months, the same as poor-risk patients (p = 0.003). In the multivariate analysis, trying to find out which of the IMDC factors had a more remarkable weight in the prognosis of the patients, both ECOG and hemoglobin levels by themselves were significantly associated with OS. CONCLUSION: In our group of patients, survival outcomes were different among patients with intermediate-risk with 1 or 2 risk factors by IMDC criteria. These could help select patients that may benefit from first-line treatment with a TKI, particularly in settings with difficult access to novel therapies, such as immunotherapy-based combinations.

RESUMEN

The Mayo Adhesive Probability (MAP) score is a radiographic scoring system that predicts the presence of adherent perinephric fat (APF) during partial nephrectomies (PNs). The purpose of this systematic review is to summarize the current literature on the application of the MAP score for predicting intraoperative difficulties related to APF and complications in laparoscopic PNs. Three databases, PubMed, Scopus and Cochrane, were screened, from inception to 29 October 2023, taking into consideration the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Guidelines. All the inclusion criteria were met by eight studies. The total operative time was around two hours in most studies, while the warm ischemia time was <30 min in all studies and <20 min in four studies. Positive surgical margins, conversion and transfusion rates ranged from 0% to 6.3%, from 0% to 5.0% and from 0.7% to 7.5%, respectively. Finally, the majority of the complications were classified as Grade I-II, according to the Clavien-Dindo Classification System. The MAP score is a useful tool for predicting not only the presence of APF during laparoscopic PNs but also various intraoperative and postoperative characteristics. It was found to be significantly associated with an increased operative time, estimated blood loss and intraoperative and postoperative complication rates.

RESUMEN

BACKGROUND: To maximize the availability of suitable grafts and ensure effective management, several reports have demonstrated successful outcomes when using kidney grafts with urolithiasis. This multicenter study reports on the management and long-term outcomes of kidney transplantation using renal grafts with lithiasis. METHODS: Retrospective data from three Spanish hospitals were analyzed for kidney transplants involving grafts with nephrolithiasis performed between December 2009 and August 2023. The study included adult patients, excluding those with incomplete records. It evaluated stone characteristics, complications, and outcomes in recipients and in living kidney donors. RESULTS: Out of 38 analyzed kidney transplants, 57.9% were cadaveric and 42.1% were from living kidney donors. Most diagnoses were incidental during donor evaluation, with an average stone size of 7.06 mm. After follow-up (median 26 months), all recipients but one had functioning grafts, and there were no stone recurrences in both recipients and living kidney donors. Conservative management was adopted in 28 cases, while 10 cases required ex-vivo flexible ureterorenoscopy for stone removal. Following conservative management, 5 patients needed additional treatments for stone-related events. CONCLUSIONS: Kidneys with lithiasis can be considered for transplantation in selected cases, resulting in good functional outcomes with no stone recurrence in recipients or living donors.

RESUMEN

BACKGROUND: The European Association of Urology (EAU) recommends discussing upfront radical cystectomy for all patients with very high risk (VHR) non-muscle-invasive bladder carcinoma (NMIBC), but the role of bacillus Calmette-Guérin (BCG) treatment remains controversial. OBJECTIVE: To analyze oncological outcomes in VHR NMIBC patients (EAU risk groups) treated with adequate BCG. DESIGN, SETTING, AND PARTICIPANTS: A multi-institutional retrospective study involving patients with VHR NMIBC who received adequate BCG therapy from 2007 to 2020 was conducted. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: A survival analysis estimated recurrence-free survival (RFS), progression-free survival (PFS), and the cumulative incidence of cancer-specific mortality (CSM) after accounting for other causes of mortality as competing risk events and of the overall mortality (OM). Conditional survival probabilities for 0-4 yr without events were computed. Cox regression assessed the predictors of oncological outcomes. RESULTS AND LIMITATION: A total of 640 patients, with a median 47 (32-67) mo follow-up for event-free individuals, were analyzed. High-grade RFS and PFS at 5 yr were 53% (49-57%) and 78% (74-82%), respectively. The cumulative incidence of CSM and OM at 5 yr was 13% (10-16%) and 16% (13-19%), respectively. Conditional RFS, PFS, overall survival, and cancer-specific survival at 4 yr were 91%, 96%, 87%, and 94%, respectively. Cox regression identified tumor grade (hazard ratio [HR]: 1.54; 1.1-2) and size (HR: 1.3; 1.1-1.7) as RFS predictors. Tumor multiplicity predicted RFS (HR: 1.6; 1.3-2), PFS (HR: 2; 1.2-3.3), and CSM (HR: 2; 1.2-3.2), while age predicted OM (HR: 1.48; 1.1-2). CONCLUSIONS: Patients with VHR NMIBC who receive adequate BCG therapy have a more favorable prognosis than predicted by EAU risk groups, especially among those with a sustained response, in whom continuing maintenance therapy emerges as a viable alternative to radical cystectomy. PATIENT SUMMARY: Our research shows that a sustained response to bacillus Calmette-Guérin in patients can lead to favorable outcomes, serving as a viable alternative to cystectomy for select cases.

RESUMEN

OBJECTIVES: Laparoscopic radical nephrectomy is considered to be the technique of choice in the management of stage T1 and T2 renal cancer, through increased expertise in this alternative type of surgery has served to expand its indications. In any case, these procedures have a series of limitations which are tied to the intrinsic characteristics of laparoscopic surgery, and associated with patient and tumor characteristics, and surgeon's expertise. METHODS: We performed a bibliographic review through Pub Med database. RESULTS: The present study discusses the different indications and establishes the current limits of laparoscopic surgery applied to the management of renal tumors (including T3 and T4). Its role in cell reducing therapy for metastatic disease, and the available methods to reduce tumor implantation in the surgical ports are also commented. CONCLUSIONS: Radical laparoscopic surgery is the technique of choice for the treatment of renal tumors in stage T1 and T2. There are not significant differences among the different approaches, and it has lower incision-related morbidity compared to traditional surgery, a shorter period of convalescence and the same oncological efficacy.

RESUMEN

OBJECTIVES: Testosterone deficit syndrome (TDS)is a clinical and biochemical entity characterized by low testosterone levels and androgenic deprivation clinic, which can cause a decrease in the quality of life. However, today there are doubts about its diagnosis and therapeutic management. METHODS: Bibliographic review using the MedLine database and detailed presentation of one clinical case. RESULTS: Testosterone deficit syndrome is associated with metabolic syndrome (visceral obesity, arterial hypertension, diabetes mellitus and dyslipemia). Currently, the performance of TDS screening in all males over the age of 45 years is under discussion. We propose a diagnostic-therapeutic algorithm for the management of TDS and erectile dysfunction. CONCLUSIONS: The treatment of erectile dysfunction associated with late start hypogonadism follows the same steps tha other generic cases of erectile dysfunction.
