RESUMO
PURPOSE OF REVIEW: Approximately, 25% of the patients with ESRD will enter the waiting list for kidney transplantation. Among these patients, almost 15% will require a retransplantation surgery. This review aims to summarize the most recent information on different controversial issues regarding retransplantation, to provide the reader with a clear and updated view on the topic. RECENT FINDINGS: Despite current evidence is mainly based on retrospective, small, single-center experiences, it seems clear that retransplantation remains a surgical and immunological challenge, for which the perioperative management still remains crucial to avoid mishaps. Different surgical approaches have been tested, but the general consensus advocates for the heterotopic extraperitoneal in first instance. Although higher immunological risk and complication rates are reported invariably in the available series, the benefits in terms of overall survival are superior to those obtained under dialysis, thus still representing the most recommended option for this group of patients.

PURPOSE OF REVIEW: To provide the critical elements to effectively manage hemorrhage from vascular injuries sustained during planned urological interventions. RECENT FINDINGS: The frequency of intraoperative vascular injuries is increasing. However, literature concerning the management of iatrogenic operative vascular injuries is scarce. Although rare, intraoperative vascular injuries may be associated with potential catastrophic complications and death. The decision-making process following a potential life-threatening intraoperative vascular injury occurs in a very short time frame. Appropriate knowledge of the critical elements to identify the source of bleeding, initiate first-line hemostatic measures, select the candidate for damage control strategies, and perform the indicated operative repairing maneuvers and techniques have been proved crucial to ensure hemodynamic stability and bleeding cessation. The key surgical principles to counteract the impact of exsanguinating bleeding, and the aim to obtain the best achievable outcomes after definitive repair, are described in detail in this review.

Rectourethral fistula (RUF) is a rare condition that occurs, in most cases, as a consequence of prostate cancer treatments. Clinical suspicion and proper assessment prior to surgery are essential to adapt and successfully carry out an appropriate treatment plan. There are no randomized trials to guide clinical practice, and therefore, scientific evidence in this respect is limited. Expert recommendations seem to agree on the transperineal approach with flap interposition as the surgical treatment of choice in cases of complex fistulas, especially in those that have undergone prior radiation. Undoubtedly, the key to the successful treatment of the disease is the multidisciplinary and standardized management by physicians with experience in the field.

INTRODUCTION: Among the many treatments for erectile dysfunction, implantation of a penile prosthesis has been associated with high patient satisfaction rates. Prosthesis replacement has become an accepted procedure in the event of device malfunction or complications, but to our knowledge, there are no data regarding the impact of implant replacement on patients and partner satisfaction. AIM: The aim of our study was to assess and to compare the level of satisfaction, with a first or second penile prosthesis implantation (PPI), in men with refractory erectile dysfunction and their partners. METHODS: A survey study based on a five-item questionnaire was carried out at our center between January 1999 and January 2012. MAIN OUTCOME MEASURES: The main outcome measure used was the level of patient and partner satisfaction with sexual intercourse after PPI. RESULTS: Of the 190 eligible patients, 149 (78%) completed the survey (110 underwent a first implant and 39 a reimplant). Seventy-nine percent of first-time implanted patients and 80% of the reimplanted patients (P > 0.05; not significant [ns]) reported satisfactory sexual intercourse (very or moderately satisfied), while 74% and 80% of their partners reported satisfactory intercourses, respectively (P > 0.05; ns). Overall, 73.7% of first implants and 70% of second implants reported that they would undergo the procedure again if the PPI failed (P > 0.05; ns). With regards to cosmetic aspects, 13% of the first implants' and 15% of second implants' partners reported either penile shortness or soft glans as the main causes of their dissatisfaction. Only 2.4% of first implants and 1% of reimplanted patients expressed difficulty in manipulating the device. CONCLUSIONS: PPI is successful in returning the ability for satisfactory sexual intercourse to both first implant and reimplanted patients and their respective partners.

PURPOSE: We report time to erectile function (EF)-recovery data from a multicenter, randomized, double-blind, double-dummy, placebo-controlled trial evaluating tadalafil started after bilateral nerve-sparing radical prostatectomy (nsRP). METHODS: Patients ≤68 years were randomized post-nsRP 1:1:1 to 9-month double-blind treatment (DBT) with tadalafil 5 mg once daily (OaD), 20 mg tadalafil on demand ("pro-re-nata"; PRN), or placebo, followed by 6-week drug-free washout (DFW) and 3-month open-label OaD treatment. Secondary outcome measures included Kaplan-Meier estimates of time to EF-recovery (IIEF-EF ≥ 22) during DBT (Cox proportional hazard model adjusting for treatment, age, and country). RESULTS: A total of 423 patients were randomized to tadalafil OaD (N = 139), PRN (N = 143), and placebo (N = 141); 114/122/155 completed DBT. The proportion of patients achieving IIEF-EF ≥22 at some point during DBT with OaD, PRN, and placebo was 29.5, 23.9, and 18.4 %, respectively. DBT was too short to achieve EF-recovery (IIEF-EF ≥ 22) in >50 % of patients; median time to EF-recovery was non-estimable. Time for 25 % of patients to achieve EF-recovery (95 % CI) was 5.8 (4.9, 9.2) months for OaD versus 9.0 (5.5, 9.2) and 9.3 (9.0, 9.9) months for PRN and placebo, respectively. Showing a significant overall treatment effect (p = 0.038), the probability for EF-recovery was significantly higher for OaD versus placebo [hazard ratio (HR); 95 % CI 1.9; 1.2, 3.1; p = 0.011], but not for PRN versus placebo (p = 0.140). Of 57 OaD patients (41.0 %) with ED improved (by ≥1 IIEF-EF severity grade) at the end of DBT, 16 (28.1 % of 57) maintained this improvement through DFW and 27 (47.4 %) declined but maintained improvement from baseline after DFW. CONCLUSIONS: Data suggest that the use of tadalafil OaD can significantly shorten the time to EF-recovery post-nsRP compared with placebo.

OBJECTIVES: There are various treatments forprostate cancer nowadays, including techniques that have been used for manyyears such as surgery and radiotherapy, and newer procedures that are gaining prominence in the Urological field like cryotherapy or HIFU (high intensity focused ultrasound). Rectourethral fistula is a rare complication that demands the urologist a great capacity; it may happen after either existent treatment. METHODS: PubMed literature review with articles published during the last 10 years using the terms "rectourethral fistula" and "prostate cancer". EVIDENCE SINTHESIS: We present the current situation of rectourethral fistula secondary to prostate cancer in terms of epidemiology, diagnosis and treatment, with special focus on the various types of fistulae and their management. We comment on general features in relation to surgical management of this pathology; type of approach, type of repair, use of flaps, concomitant fistula and urethralstenosis, delay of surgery and bowel diversion. We describe the surgical techniques more frequently used today and their limitations. We present the results published by different groups with each of these techniques, as well as the corresponding recommendations based on each group's experience. CONCLUSIONS: Rectourethral fistula is a surgical challenge for the urologist. We must choose the appropriate management in accordance to the characteristics of the fistula.

Penile prosthesis (PP) is the mainstay of treatment in Peyronie's disease (PD) with co-existent refractory erectile dysfunction (ED). This study aimed to assess the clinical outcomes of patients who underwent PP as the first-line surgical treatment in PD without ED. A total of 636 patients underwent PP for PD from 2012 to 2022, but only 168 patients who underwent PP as first-line surgical management for PD with or without ED were included in the study. The mean (SD) age of 168 patients was 56.3 years (12.4). The mean curvature of the "PD with ED" group and the "PD without ED" group were 38.2 (5.6) degrees and 42.2 (5.9) degrees. The median (IQR) follow-up was 56.0 months (34.5- 61.4). Most (86.9%) patients underwent 3-piece inflatable PP. An important finding is that 33 patients (19.6%) without ED had undergone PP. Mechanical failure requiring revision surgery was less common in the 'without ED' group than in the ED group (6.8% vs. 10.2%, p 0.04). Most PD patients without ED (87.9%, 29/33) and with ED (88.9%, 120/135) were "satisfied" after PP implantation at six months, as defined by a score of ≥4 on a 5-point Likert scale. If surgery is offered in PD, PP may be considered a safe and effective first-line surgical treatment regardless of the ED, given the acceptable complications and high satisfaction rates. However, this new concept warrants further research.
RESUMO
Hypogonadism may affect as much as 70% of the patients with chronic renal failure (CRF) in comparison with general population. Physiopathologically, it is a hypergonadotropic hypogonadism, with alterations in the pulsatile production of GnRH, FSH, LH and testicular testosterone, that is a general disorder of the hypothalamic-hypophysis-testicular axis. This disorder may determine important consequences in this population of patients, with varied sexual dysfunction, trophic and functional muscular and fatty tissue disorders, bone demineralization, anemia and increase of cardiovascular disease associated mortality.Treatment in these patients must be focused from a general point of view, increasing their clinical condition, the systemic complications associated with CRF, complementing in this way with exogenous testosterone replacement therapy. If possible, it seems that the most efficacious therapy will be renal transplantation.

OBJECTIVES: To identify risk factors for progression in patients with invasive bladder carcinoma who were pT0/pT1/pTa after cystectomy. METHODS: We analyzed the clinical records of 97 post-cystectomy pT0/pT1/pTa patients for the following variables: hydronephrosis, carcinoma in situ (CIS), lymphovascular invasion, history of non-muscular invasive disease, residual tumor in the specimen and lymphatic invasion (pN). pN+patients were excluded from definitive analysis. The quantitative and qualitative variables were analyzed using standard statistics. The chi-square test was used to analyze associations between categorical variables. Univariate Cox proportional hazard regression analysis (enter method) was performed. The Kaplan-Meier method was used to evaluate survival and the log-rank test to assess differences between groups. Statistical significance was set at p<0.05. The analysis was performed using SPSS version 15.0. RESULTS: The study sample included 97 cases. The specimen was staged at T2 in 97% of patients after transurethral resection (TUR); After cystectomy, the specimen was staged as pT0 (R0) in 44.3% and pT1/Ta (R1) in 55.7%. Median follow-up was 47 months. Lymph node metastasis were detected in 5.2% of patients (pN+rpar; and had a negative impact on survival (p=0.02). Overall survival was 59.8% and cancer-specific survival 76.6%. Univariate analysis showed a relationship between tumor progression and the presence of CIS (p < 0.001), lymphovascular invasion (p=0.049), and hydronephrosis(p < 0.001). In the multivariate analysis, only the presence of CIS in the transurethral resection was associated with reduced cancer-specific survival (HR 100.5; 95% CI, 10.8 to 933.1; pp<0.001). CONCLUSIONS: Although the prognosis of stage pT0/pT1/pTa carcinoma in the cystectomy specimen is excellent, some patients experience progression. The presence of CIS in the transurethral resection was an independent predictor of recurrence in these cases.

OBJECTIVE: Literature review of adenocarcinoma of the urachus in connection with two cases recently diagnosed and treated in our center. METHODS/RESULTS: We report 2 cases of urachus Adenocarcinoma treated in our institution, both underwent extended partial cystectomy including excision of the urachus up to the umbilicus. CONCLUSION: Urachal adenocarcinoma is an exceptional tumor, of poor prognosis, the treatment of which is surgical (partial cystectomy), and the main predictors of disease-free survival are the degree of tumor differentiation and the free margins of the surgical specimen.

Targeted therapy (TT) for prostate cancer (PCa) aims to ablate the malignant lesion with an adequate margin of safety in order to obtain similar oncological outcomes, but with less toxicity than radical treatments. The main aim of this study was to evaluate the recurrence rate (RR) in patients with primary localized PCa undergoing mpMRI/US fusion targeted cryotherapy (FTC). A secondary objective was to evaluate prostate-specific antigen (PSA) as a predictor of recurrences. We designed a prospective single-center single-cohort study. Patients with primary localized PCa, mono or multifocal lesions, PSA ≤ 15 ng/mL, and a Gleason score (GS) ≤ 4 + 3 undergoing FTC were enrolled. RR was chosen as the primary outcome. Recurrence was defined as the presence of clinically significant prostate cancer in the treated areas. PSA values measured at different times were tested as predictors of recurrence. Continuous variables were assessed with the Bayesian t-test and categorical assessments with the chix-squared test. Univariate and logistic regression assessment were used for predictions. A total of 75 cases were included in the study. Ten subjects developed a recurrence (RR: 15.2%), while fifty-six (84.8%) patients showed a recurrence-free status. A %PSA drop of 31.5% during the first 12 months after treatment predicted a recurrence with a sensitivity of 53.8% and a specificity of 79.2%. A PSA drop of 55.3% 12 months after treatment predicted a recurrence with a sensitivity of 91.7% and a specificity of 51.9%. FTC for primary localized PCa seems to be associated with a low but not negligible percentage of recurrences. Serum PSA levels may have a role indicating RR.
RESUMO
PURPOSE: We designed an experimental model of renal ischemia-reperfusion to evaluate the preemptive effect of intravenous sildenafil according to the dose administered (0.7 vs 1.4 mg/kg) and the time of administration (30 minutes before ischemia or during ischemia). MATERIALS AND METHODS: A total of 20 minipigs were divided into groups of 4 each, including group 1-control, group 2-sildenafil 0.7 mg/kg intravenously 30 minutes before vascular clamping, group 3-sildenafil 0.7 mg/kg intravenously during warm ischemia, group 4-sildenafil 1.4 mg/kg intravenously 30 minutes before vascular clamping and group 5-sildenafil 1.4 mg/kg intravenously during warm ischemia. The ischemia-reperfusion model was applied using laparotomy and right kidney vascular clamping for 30 minutes, followed by unclamping and reperfusion for 45 minutes. Renal vascular flow and systemic mean arterial pressure were recorded for 45 minutes after unclamping. Mean values were compared using Student t test with significance considered at p <0.05. RESULTS: Sildenafil led to a decrease in arterial pressure compared to that in controls, especially at the dose of 1.4 vs 0.7 mg/kg, including 113.77, 109.76, 106.12, 97.41 and 82.85 mm Hg in groups 1 to 5, respectively. Renal vascular flow was significantly higher in groups 2 and 3 than in groups 1, 4 and 5 (112.82 and 111.33 vs 88.25, 87.91 and 84.37 ml per minute, respectively, p = 0.000). CONCLUSIONS: The effect of intravenous sildenafil as a preemptive drug against the hemodynamic effects of renal ischemia-reperfusion is dose dependent. The 0.7 mg/kg dose significantly increased reperfusion renal vascular flow with a small decrease in arterial pressure compared to the 1.4 mg/kg dose.

PURPOSE: We compared the outcome of second and third kidney allografts with that of the first kidney allograft in pediatric recipients. MATERIALS AND METHODS: We classified 173 cadaveric kidney recipients into 2 groups. Group 1 comprised 120 first transplants and group 2 comprised 53 retransplants, including 43 second and 10 third transplants. We compared demographic characteristics and survival in groups 1 and 2. RESULTS: Group 1 consisted of 78 boys and 42 girls with a mean ± SD age of 11.5 ± 4.2 years. Group 2 consisted of 37 boys and 16 girls with a mean age of 10.4 ± 4.7 years. One, 5, 10 and 15-year graft survival rates were 78.7%, 64.3%, 54.5% and 50.7% for first transplants vs 82.8%, 57.8%, 57.8% and 41.3%, respectively, for retransplants (p = 0.757). Patient survival at 1, 5 and 15-year was 95.8%, 89.6%, 84.9% in the first transplant group vs 93.6%, 93.6% and 93.6%, respectively, in the retransplant group (p = 0.0.63). Graft survival was significantly higher in patients who did vs did not receive calcineurin inhibitors in the 2 groups (p = 0.02). CONCLUSIONS: Kidney retransplantation in the pediatric population can yield excellent long-term outcomes, especially in patients treated with calcineurin inhibitors.

PURPOSE: In an experimental model we studied the protective effects of the phosphodiesterase-5 inhibitor sildenafil on kidney grafts autotransplanted after 45 minutes of warm ischemia by vascular clamping, nephrectomy and 60 minutes of isolated hypothermic pump perfusion. MATERIALS AND METHODS: A total of 14 laboratory minipigs were divided into group 1-7 administered 100 mg sildenafil orally 1.5 hours preoperatively and group 2-7 in which no sildenafil was given. Right single nephrectomy was completed after 45 minutes of warm ischemia by complete vascular clamping. Before autotransplantation all kidneys underwent 60 minutes of hypothermic pulsatile perfusion. Renal flow, arterial pressure and renal vascular resistance were recorded in real time for 60 minutes after autotransplantation. Nitric oxide levels were determined in blood samples from the renal vein at predefined intervals. Optical and electronic microscopy was done in all organs at the end of the procedure. RESULTS: In group 1 vs 2 renal vascular flow was significantly higher (155.30 vs 29.04 ml per minute per 100 gm) and renal vascular resistance was significantly lower (0.59 vs 3.10 mm Hg/ml per minute, each p <0.01). No significant differences were observed in systemic arterial pressure between groups 1 and 2 (84.08 and 84.65 mm Hg, respectively, p >0.05). Nitric oxide levels were significantly higher for all periods in group 1 (49.94 vs 16.85 muM, p <0.01). No significant differences were observed in histological studies, although endothelial cell structure was better preserved in the sildenafil group. CONCLUSIONS: To our knowledge our study suggests for the first time in the literature a positive effect of sildenafil in the immediate posttransplantation outcome of warm ischemic kidneys without secondary systemic effects.

This article reviews the mechanisms of action of high-intensity focused ultrasound (HIFU), as well as both experimental and clinical work related to renal tumor treatment. While most currently available experience in urological tumors with HIFU has been obtained with prostate cancer, an increasing number of studies support the efficacy and safety of this procedure for renal tumor destruction. HIFU completes, with cryotherapy and radiofrequency, the spectrum of minimally invasive surgery in renal cancer, intended to decrease surgical morbidity while achieving similar oncological control rates. It is still early to recommend this procedure for daily clinical practice because, while its safety and few side effects are known, many ongoing studies intended to confirm its mid- and long-term oncological efficacy should be completed.

INTRODUCTION: Prostate cryotherapy has been consolidated as an alternative minimally invasive treatment. OBJECTIVE: To exposed its historical development, its action mechanism and the surgical technique. Regarding its indications, we expose the different option of treatment- primary cryotherapy, salvage and focal- emphasizing its oncological results in the absence of randomized studies. RESULTS: Cryotherapy is a safe technique with low complication rate, although incidence of erectile dysfunction is 40-90% in case of full-gland cryotherapy. Nowadays, it is recommended as a therapeutic alternative for low and intermediate risk localized prostate cancer, although in clinical trials. Recurrence-free survival is close to 96% in low-risk tumors and 90% in intermediate-risk tumors. On the other hand, it is a salvage treatment option for local recurrence after radiotherapy. Focal therapies including focal cryoablation have an important development, with recurrence-free survival of 75%. CONCLUSION: Waiting for randomized studies that provide more scientific evidence, available retrospective studies show cryotherapy as a safe and effective treatment option in patients with localized prostate cancer.
INTRODUCCIÓN: La crioterapia prostática se ha ido consolidando como una alternativa de tratamiento mínimamente invasiva. OBJETIVO: Exponer el desarrollo histórico de la crioterapia, su mecanismo de acción sobre el tejido prostático así como la técnica quirúrgica. Se discuten los distintos escenarios crioterapia primaria, de rescate y focalhaciendo énfasis en sus resultados oncológicos a falta de estudios randomizados. RESULTADOS: La crioterapia es una técnica segura con un bajo índice de complicaciones, aunque destaca una incidencia de disfunción eréctil del 40-90% en el caso de crioterapia de glándula completa. En la actualidad se recomienda como alternativa terapéutica en el cáncer de próstata localizado de riesgo bajo e intermedio, aunque dentro de ensayos clínicos. La supervivencia libre de recidiva bioquímica es cercana al 96% en tumores de bajo riesgo y al 90% en tumores de riesgo intermedio. Por otro lado, es una opción de tratamiento de rescate en el caso de recidiva local tras radioterapia siempre que se cumplan una serie de criterios (Gleason ≤7 y PSA10ng/ml). La mejora en las técnicas de imagen está permitiendo el desarrollo de terapias focales incluyendo la crioablación focal, con supervivencia libre de recidiva bioquímica del 75%. CONCLUSIONES: A la espera de estudios randomizados que aporten mayor evidencia científica, los estudios retrospectivos disponibles muestran la crioterapia como una opción de tratamiento segura y eficaz en pacientes con cáncer de próstata localizado.

INTRODUCTION: Surgical intervention in Peyronie's disease (PD) should ideally be delayed until the resolution of acute inflammatory phase. AIM: The objective of this review was to highlight the results of penile prosthesis to correct refractory erectile dysfunction (ED) in patients with PD, and the secondary procedures that may be required to correct the penile curvature. METHODS: A systematic search on PubMed online database using Preferred Reporting Items for Systematic Reviews and Meta-Analyses recommendations was done using the MeSH terms "Peyronie's disease" and "erectile dysfunction." MAIN OUTCOME MEASURE: Success and satisfaction rates of various procedures. RESULTS: The search yielded 324 language-specific (English and Spanish language) articles and 58 articles were retained for final review. The following variables were assessed in different studies: number of patients, types of secondary procedure to correct the curvature, satisfaction rates, and follow-up period. CONCLUSION: The aim of the surgery in PD should be to achieve a functionally straight penis (<20 degree curvature) with good erection. Patients with refractory ED in PD are candidates for penile prosthesis. Secondary procedures, like manual modeling, plication, plaque incision, or excision grafting, may be required depending on the degree of penile curvature and penile length. In quest for the best graft, TachoSil graft seems to have gained popularity in Europe. Krishnappa P, Fernandez-Pascual E, Carballido J, et al.

RESUMO
INTRODUCTION: Radical cystectomy (RC) with pelvic lymphadenectomy is the treatment of choice in patients with muscle invasive bladder cancer (MIBC). OBJECTIVE: To identify clinical and pathological variables that influence global mortality (GM) and cancer specific mortality (CSM) in patients with urothelial bladder tumor (UBT) treated with RC. METHODS: Retrospective analysis of 517 patients diagnosed with UBT and treated with RC between 1986 and 2009. Demographic, clinical, surgical and pathological variables, as well as complications and evolution after RC were collected. A comparative analysis was carried out with Chi square and ANOVA test. Survival analysis was performed with the Kaplan-Meier method and the long-rank test. Univariate and multivariate analysis were performed using Cox regression to identify independent predictors of GM and CSM. RESULTS: 91% of the patients were males with a median age of 66 years. The most frequent local pathological stage was pT3 (32.6%), with lymph node involvement in 23.8% of the patients. After a median follow-up of 34 months, 170 patients were alive and 311 had died from any cause (63.5%), being UBT the cause of death in 225 patients (45%). Rates of global survival and cancer specific survival at 5 and 10 years were 45%/34.3% and 52.5%/46.6% respectively. On the multivariate analysis age ( p = 0.004), ASA ( p = 0.000), the existence of hydronephrosis ( p = 0.01), pT ( p = 0.000) and pN ( p = 0.003) were identified as independent predictors of GM, as well as pT ( p = 0.000) and pN ( p = 0.002) for CSM. CONCLUSIONS: Age, anesthetic risk, presence of hydronephrosis, pT and pN stage were identified as independent predictors of GM, as well as pT and pN stage for CSM.

Análisis univariante y multivariante mediante regresión de Cox para identificar variables predictoras independientes de MG y MCE. RESULTADOS: El 91% de los pacientes fueron varones con mediana de edad de 66 años. El estadio patológico local más frecuente fue el pT3 (32,6%), con afectación ganglionar en el 23,8% de los pacientes. Tras mediana de seguimiento de 34 meses, 170 pacientes estaban vivos y 311 habían fallecido por cualquier causa (63,5%), siendo el TUV la causa de muerte en 225 pacientes (45%). Se objetivaron tasas de supervivencia global y cáncer específica a 5 y 10 años del 45/34,3% y del 52,5/46,6% respectivamente. En el análisis multivariante se identificaron la edad ( p = 0,004), el ASA ( p = 0,000), la existencia de hidronefrosis ( p = 0,01), el pT ( p = 0,000) y el pN ( p = 0,003) como variables predictoras independientes de MG, así como el pT ( p = 0,000) y pN ( p = 0,002) para MCE. CONCLUSIONES: La edad, el riesgo anestésico, la presencia de hidronefrosis, el estadio pT y pN se identificaron como variables predictoras independientes de MG, así como el estadio pT y pN para MCE.

Acute thrombophlebitis of spermatic vein is an unusual pathology involving, in most of the cases, the left side, and whose etiology remains uncertain. Most of them are found during a a differential diagnosis in acute testicular pain. We introduce the case of a 29 years old male with abusive cocaine consumption, admitted to hospital due to severe testicular pain. Doppler-ultrasound examination was undertaken, showing right spermatic vein flux alteration. Conservative management was decided and anticoagulant and non-esteroidal anti-inflammatory drugs were started. Eco-doppler is the most specific and sensible technique for diagnosis of these cases, while TC can always confirm etiologic diagnosis. Treatment was initially conservative based on anticoagulation. Hematological study is necessary in order to determine coagulation alterations.
