OBJECTIVE: To determine the clinical-surgical factors associated with Complex Urethral Surgery (CUC) in anterior urethral stenosis.MATERIAL AND METHOD: This is a cross-sectional study with retrospective data recording, including all male patients who underwent anterior urethroplasty between 2011 and 2018. CUC included two or more grafts urethroplasty, excisional augmented anastomotic urethroplasty, combined flaps and grafts urethroplasty and stages surgery. The data were collected from theelectronic medical record, recording the demographic data, background of previous treatments as well as the characteristics of the stenosis (etiology, anatomical location, length, number of strictures, among others). A univariate and multivariate analysis were conducted using the chi-squared test and logistic regression to identify the variables related to CUC.RESULTS: The data of 665 patients met the inclusion criteria were analyzed. The mean age was 56.1 years, 27.5% were smokers, 32.5% had received some previous treatment, and dilatations were the most common procedure. The most prevalent etiology was iatrogenic, followed by idiopathic in a 61.1 and 20.3% respectively. Bulbar urethral stricture were the most common location (56.2%) while the mean length of the stenosis was 4.8 cm. After univariate and multivariate analysis, previous dilations (HR 2.6), multifocality (2.51), length of stenosis (>4 cm) (HR 1.49) and the hypospadias etiology (HR 11.9) were independent predictors for CUC (p<0.05).CONCLUSIONS: Hypospadias was the only etiology factor that predicts the need for CUC. Regarding radiological findings, extensive and multifocal stenosis, were predictors of complex surgery. History of previous dilations were also predictors of CUC.

OBJECTIVE: To compare the classification CAPRA (based on clinical-pathological findings) and minimal residual disease (MRD) (based on biological characteristics) to predict biochemical failure (BF).METHOD AND PATIENTS: The clinical-pathological findings of the prostate biopsy were used to determine the CAPRA score, classifying patients into low, intermediate and high risk. Blood and bone marrow samples to detect circulating prostate cells (CPCs) and micro-metastasis were taken. The samples were classified as positive if ≥1 prostate cell was detected, forming three subgroups; Group A (MRD negative), Group B (micro-metastasis positive, CPC negative) and Group C (CPC positive). Patients were followed-up for 10 years or BF. Kaplan-Meier biochemical failure free survival (BFFS) curves, a predictive flexible parameter survival model and mean restricted survival times (MRST) were determined. RESULTS: 347 men participated, BF risk increased with increasing CAPRA score, HR 1.21 intermediate, 1.64 high risk; versus MRD HR 1.91 and 4.43 for Groups B and C. After 10 years the BFFS and MRST were 76%, 50% and 17% and 9, 7 and 5 years respectively for CAPRA versus 94%, 57% and 26% and 10, 9 and 6 years respectively for MRD. The concordance between observed and predicted BFFS was acceptable for CAPRA (Harrell´s C 0.64) and very good (0.92) for MRD. The BFFS curves for MRD were not proportional with time, they were similar for 5 years for Groups A and B, with increasing BFFS in Group B thereafter. The CAPRA score did not distinguish between Groups A and B, one third of low risk CAPRA patients had CPCs detected. CONCLUSIONS: The MRD classification was superior to CAPRA, differentiating between early and late failure.

INTRODUCTION: Colposacropexy is the treatment of choice for apical prolapse. Studies comparing this technique as primary surgery for pelvic organ prolapse (POP), with its success in recurrent POPs after surgery, are scarce. MATERIALS AND METHODS: Retrospective analysis of a series of patients diagnosed with POP who underwent laparoscopic colposacropexy, comparing a group without previous prolapse surgery with another group that has recurred after previous surgery (with or without mesh). Our objective was to analyze the differences regarding surgical time (skin to skin), intraoperative complications, mean stay, resolution of symptoms and recurrence. As preoperative data, we compared: age, body mass index (BMI), parity, previous hysterectomy, physical examination, symptoms, and flowmetry; and as peri/postoperative data: follow-up, intervention duration, intra and postoperative complications, mean stay, physical examination (Baden-Walker classification), symptom resolution and flowmetry. RESULTS: Twenty-three patients have been operated on in 12 months. Nine (39.1%) were recurrent POPs after previous surgery, 6 (66.7%) of them with some type of mesh. Follow-up (mean months): 6.44 ± 4.19 (previous cx) vs. 4.79 ± 4.00. Both groups were comparable with respect to preoperative variables. Previously operated patients had greater dyspareunia (p<0.05). We did not find differences in the rest of symptoms between both groups. There were no differences in the duration of the intervention, mean stay, or regarding intraoperative complications (p>0.05) between both groups. Sensation of vaginal lump, urge incontinence and dyspareunia resolved in all patients. Flowmetry improved in both groups (p>0.05). CONCLUSIONS: Laparoscopic colposacropexy is an effective and safe technique to correct POP after previous surgery, with or without mesh.

INTRODUCTION AND OBJECTIVES: Juvenile gangrenous vasculitis of the scrotum was described by the Girona dermatologist Joaquín Piñol Aguadé in 1973.The objectives of this article are to review the world publications and provide a clinical case of this disease between urological and/or dermatological.MATERIAL AND METHODS: A review of juvenile gangrenous vasculitis of the scrotum between 1973 and 2019 is carried out and a new clinical case is contributed. The identification of articles in Medline was carried out with MeSH terms “juvenile gangrenous vasculitis scrotum” and in Google with “juvenile gangrenous vasculitis scrotum”. Ten clinical-epidemiological variables were studied in the articles: year, source, authors, number of cases, age, previous pharyngo-tonsillitis, biopsy of the lesion, treatment, days to healing, city and country. The results of the variables were analyzed with descriptive statistics. A new clinical case is described.RESULTS: We found 26 world references, 18 of them Spanish, corresponding to 24 publications and 2 conference papers with a total of 29 patients. The mean age of the patients was 23.6 years. The treatments used were exeresis of the lesion (23%), cephalosporins and/or corticoids i.v. (15.3%), tetracyclines, ciprofloxacin or oral amoxicillin-clavulanate (15.3%), local cure and oral corticoids (11.5%) and mupirocin or topical tetracyclines (7.6%). Healing took place in an average of 21 days. The cities with the most cases reported were Barcelona with 11 (37.9%) and Pontevedra with 2 (6.8%). By country, Spain contributed 22 cases (75.8%) and Chile, Argentina, Portugal, Italy, Tunisia, Turkey and Great Britain the remaining 7 cases (24.1%). CONCLUSIONS: Juvenile gangrenous vasculitis of the scrotum is a benign entity with a self-limiting course. The process is preceded by pharyngo-tonsillitis in about half of the patients. The results of the study confirm the endemic nature of the disease in Mediterranean countries, including Spain.

OBJECTIVE: To determine the prevalence and factors associated with high-grade ED in Lima, Peru. MATERIAL AND METHODS: Analytical cross-sectional study in tuberculosis patients treated in an outpatient clinic of a public hospital in Lima, Peru in 2018. Highgrade SD was the dependent variable, using the IIEF-5 questionnaire and the independent variables were sexual orientation, history of previous pathology, location of tuberculosis, type of treatment scheme and presence of hemoptysis. Prevalence ratios (PR) were estimated using simple and multiple regression models.RESULTS: Of 189 patients, the majority presented pulmonary tuberculosis (98.9%), overweight (25.9%) and just over half had high-grade ED (52.9%). In the simple regression it was found that the factors associated with presenting high-grade SD were age in years (RP=1.11), reporting diabetes (RP=2.09), having multi-drug resistant TB (RP=1.51) and presenting a treatment time from 1 year to more (RP=1.87). In the multiple regression, the variables that were associated with a higher frequency of high-grade TB were age in years (RP=1.11), a history of diabetes (RP=1.66) and having MDR TB (RP=2.04). CONCLUSIONS: This study suggests a high prevalence of ED in patients with TB, where four out of ten presented high-grade ED. Being older, having a history of diabetes and using an MDR treatment were positively associated with the development of high-grade ED. Studies with designs close to causality are required to know the real magnitude of the influence of clinical and therapeutic characteristics on the development of high-grade ED.

OBJECTIVES: The aim of this paper is to describe the clinical features and the perioperative results of the bilateral laparoscopic adrenalectomy (BLA) of salvaje in 5 patients treated for an Ectopic Cushing Syndrome (CS) who were refractory to medical treatment.MATERIALS AND METHODS: We performed a retrospective analysis of the clinical records of our institution. Five BLAs were performed in patients with Ectopic CS refractory to medical treatment during the period from January 2009 and June 2017. All patients were evaluated by a multidisciplinary team that jointly decided the most appropriate time for surgery. The following protocol data were analyzed: age, sex, location of the secreting tumor, duration of hypercortisolism, reason for hospitalization, initial therapeutic management), biochemical data (pre-op serum cortisol, plasma ACTH and free urinary cortisol), surgical data (surgical approach, surgical time, type of surgery, need for conversion to open surgery), perioperative data (post op surgical stay, post op complications according to the Clavien-Dindo scale 14, mortality, clinical cure rate and biochemical cure rate, follow up time). RESULTS: Five patients underwent BLA. The approach for the BLA was minimally invasive, either trans peritoneal (n=3) or posterior retroperitoneoscopic (n=2). Mean hospitalization time was 23.4 days (r=4-81). None of the patients died because of surgical complications, and all of them achieved biochemical and clinical remission of their hypercortisolism after surgery. CONCLUSIONS: BLA is an effective salvage alternative to control the symptoms associated with overproduction of corticosteroids in patients with ectopic CS refractory to medical treatment.

OBJECTIVES: We aimed to understand whether laparoscopic ureterolithotomy (LU) is a good alternative to flexible ureterorenoscopic lithotripsy (FURS) by comparing these techniques concerning cost-effectiveness.METHODS: We analysed 79 patients with upper ureteral stones larger than 1.5 cm underwent FURS or LU concerning cost-effectiveness analysis. The data including age, body mass index (BMI), stone size, operation time, hospitalisation time, complications and stone-free rates of 15th day and 3rd months. We audited the costs of FURS and LU and compared them concerning cost-effectiveness. RESULTS: There was not any statistically significant difference between the two groups with regard to age, BMI, stone size, stone-free rates at the 3rd month, and complication rates, (p>0.05). The operation times were statistically lower in the FURS than in the LU (61.5±24.3 min and 140.9±49.1 min, respectively, p<0.05). The stone-free rate at the 15th day was lower in the FURS group than in the LU group (31 (81.6%) and 41 (100%), respectively, p<0.05) (Table I).However, this statistical difference disappears at 3 months (p>0.05). The mean costs of FURS and LU were $194.2±12.4 and $179.2±58.5, respectively (p<0.001).CONCLUSION: FURS is equally effective to LU in terms of stone-free rates. The cost of FURS is higher statistically than LU. FURS is shown as the first choice for the upper ureteral stones larger than 10 mm in size, if the laparoscopic experience is in high-level situations in that clinic, LU may be a suitable alternative to FURS, especially for challenging cases.

OBJECTIVES: We aimed to determine the parameters that predict Gleason Score (GS) upgrading in patients undergoing robot-assisted laparoscopic radical prostatectomy (RARP) and especially the ability of neutrophile to lymphocyte ratio (NLR) in predicting the upgrading.METHODS: Patients who underwent RARP for prostate cancer in our clinic between January 2013 and January 2018 were retrospectively analyzed. Patients’ demographic data, preoperative and postoperative parameters were all recorded in the database. NLR was calculated by dividing the absolute neutrophil count (NC) by the absolute lymphocyte count (LC). Patients were classified as low, moderate and high risk according to the National Comprehensive Cancer Network (NCNN) Guidelines. Any increase in GS between biopsy results and radical prostatectomy specimens were considered as an GS upgrading.RESULTS: After applying the inclusion and exclusion criteria, a total of 571 patients, 205 patients without GS upgrading (Group 1) and 366 patients with GS upgrading (Group 2), were included. The mean preoperative PSA values and prostate volumes were 10.8 ± 8 ng/dL and 45 ± 18.8 ml, respectively. Group 2 had a significantly high NC and NLR, significantly low platelet count (PC) and LC, (p=0.0001, 0.0001, 0.001 and 0.002, respectively). Group 2 was found to have significantly higher positive surgical margin (PSM), extraprostatic extension (EPE) and seminal vesical invasion (SVI) (p<0.001). There was no significant correlation between the parameters of NLR and PSM, EPE, SVI, and lymph node invasion (LNI). Binomial logistic regression showed patients with increased NLR had 1.68 times higher odds to exhibit an upgrade in GS in the post-surgical histopathological analysis.CONCLUSIONS: NLR calculated preoperatively is an easy diagnostic method that can predict GS upgrading in patients scheduled for radical prostatectomy for prostate cancer.

OBJECTIVES: Over 50% of elderly men and 70% of male cardiac patients suffer from erectile dysfunction (ED). Although pharmacotherapy is effective and safe, it only brings a short-term improvement and may cause side effects. Low energy shock-wave therapy (LESWT) is a promising causative modality for the treatment of ED. The evidence is still limited with different results obtained using different devices. The aim of this work was to evaluate evidence from randomized controlled trials regarding the efficacy of LESWT generated by an electrohydraulic unit for the treatment of ED. METHODS: A systematic review of the literature was conducted in PubMed on May 20th, 2018 and supplemented by a Google search of grey literature, as well as a hand search of the bibliographies of retrieved articles. Out of 34 studies, 5 studies on 354 patients were included in the quantitative synthesis. RESULTS: The studies evaluated an abridged International Index of Erectile Function (IIEF-5), the Erectile Hardness Scale (EHS) and Flow-Mediated Dilatation (FMD). The meta-analysis revealed that LESWT improved the IIEF-5 score (mean difference: 5.16; 95% CI, 1.39-8.93; p=0.0073) and EHS score (risk difference: 0.72; 95% CI, 0.73-0.80; p<0.001). Reporting of FMD was inconsistent and not analyzed. The meta-analysis of studies conducted with electrohydraulic devices showed greater benefits to patients in comparison to the meta-analyses of heterogeneous studies conducted using various devices for generating shock waves.CONCLUSIONS: Evidence exists that LESWT generated with an electrohydraulic unit is effective. Further research is needed in order to evaluate this method in different patient populations and for the long-term.

OBJECTIVE: Calcification and atherosclerosis of the iliac arteries is very common in dialysis patients, making sometimes impossible the anastomosis of a kidney graft. The objective of this study is to present our kidney transplantation series using vascular prostheses for iliac artery reconstruction and to assess the results obtained in comparison to other published series. MATERIAL AND METHOD: In a single centre where 1090 kidney transplants were performed between January 2013 and December 2019, patients who required vascular reconstruction were identified for their descriptive analysis. RESULTS: In 9 patients (0.83%) arterial anastomosis was performed to a Gore-tex prosthesis (8) or using a bovine pericardium patch (1). Only in 1 case, the vascular bypass was prior to transplantation; in the other 8 the surgery was simultaneous. In 2 cases, an urgent transplantectomy was done because of acute rejection and prosthetic thrombosis. 6 patients had immediate graft function. 5 patients required a new surgical or endovascular procedure to resolve complications. At 35 months of mean follow-up, 7 patients maintained renal graft function. CONCLUSION: Kidney transplantation with arterial anastomosis to a vascular prosthesis is very rare. Candidates should be carefully selected because of the high risk of complications. Simultaneous vascular reconstruction is preferred. The functional results are satisfactory.

OBJECTIVE: The treatment of the ectopic ureter in the pediatric patient must be individualized in each caseMETHOD: Description of clinical cases, therapeutic management and evolution of patients.RESULTS: We present four pediatric patients with ectopic ureters who underwent surgery. We describe a case of laparoscopic nephroureterectomy, one of laparoscopic uretero-ureterostomy, one of bilateral ureteral reimplantation and another of unilateral reimplantation. The discussion about the diagnosis and different surgical treatments of each case is deepened.CONCLUSIONS: We present four cases of pediatric patients with ectopic ureters, treated by different surgeries. We present how was the preoperative diagnosis and the importance of individualizing the surgical treatment in each case. Aspects recently described in the context of ureteral ectopy, such as diagnostic evaluation by MRI or the role of minimally invasive techniques in treatment, should be taken into account in its management.
