RESUMO
OBJECTIVE: To analyse the clinical evolution, the therapeutic strategies and the characteristics of the patients presenting enuresis attended at our outpatient clinic. MATERIAL AND METHODS: Retrospective study of patients <14 years old(yo) diagnosed of enuresis attended at our outpatient clinic (2011-2019) and completed their follow-up (remission or aged 15). Urotherapy was offered to all patients as initial management. The therapeutic strategies were classified as: first line (desmopressin or clock alarm), second line (desmo-pressin+alarm) and third line(anticholinergics). The remission rate during follow-up, the number of consultations needed until remission and the treatments used were calculated. Statistical tests used:Kaplan-Meier, actuarial survival. Multivariate analysis:Cox regression.Statistical significance:p<0.05. RESULTS: Data were collected from 125 patients (mean age: 8.6±2.45yo). Family history of enuresis was present in 38.9%. The mean follow-up was 2.37±1.55yo and the average number of consultations was 7.54±5.06. The remission rate (RE) was 84%(n=105), with a median remission interval:2.66 years (2.34-2.991[95%CI]). The average number of treatments required for remission was 2.74±1.27. RE with urotherapy alone was 20%(n=25); RE with first line:19.3%(n=17) and second line:16.7(n=11). In the remaining patients, a RE of 78.18%(n=43) was achieved by adding an anticholinergic. Patients aged > 8.7 years at the beginning of the follow-up required less time to achieve remission (p=.025). These patients had a higher RE (hazard ratio 1.15 (1.05-1.25))(p=.004). No other variables were significant. CONCLUSION: Staged therapeutic strategies are necessary to achieve remission. Only 25% remitted with urotherapy as single treatment. RE are higher when patients are >8.7 yo once they initiate their follow up.

OBJECTIVES: To determine the usefulnessof voiding diary (VD), uroflowmetry with electromyography(UF-EMG), bladder wall thickness (before micturition)(VWTUS) and residual urine (PVR) (ultrasound measure)in predicting the outcome of the first endoscopic treatment(1ENDT) of vesicoureteral reflux (VUR) in children> 3 years. METHODS: Cross-sectional ambispective study of 48children with vesicoureteral reflux. Those with previousendoscopic treatment, age or neurological abnormalities and a history of urethralor abdominal surgery were excluded. The outcomevariable was the correctness (by isotopic cystography)three months after 1ENDT. Univariate and multivariateanalyses were performed through a Multilayer Perceptronnetwork and a logistic regression model EmpiricalBayesian penalized type LASSO Elastic net. Diagnosticaccuracy were determined. RESULTS: Mean age of the sample was 6.8 +/- 2.28years. The rate of VUR correction after 1ENDT was 77%.The variables selected by both methods were: VD-retentionist(OR 3.90), high PVR (OR 2.69), high VWTUS (OR4.44). Normal UF-EMG was a preventive variable (OR0.38). Diagnostic accuracy (pSp=48.7%), UF+EMG (Se=27.3%(Se=72.7% (AUC=0.8 cut point 20 ml),VWTUS (Se=81.8% (AUC=0.8 cut point4.6 mm). There were no statistical differences betweenPVR and VWTUS. Combined use of UF+EMG+PVR(Se=90.9%in predicting the persistence of VUR after 1ENDT inchildren > 3 years. After screening with a VD, UF-EMG+ RPM combination could be useful to detect these patientsand propose a treatment that improves bladdervoiding function prior to surgery.

OBJECTIVES: To investigate the expression of several immunohistochemical (IHC) markers and their predictive ability for the recurrence-free and progression-free survival of papillary urothelial bladder cancer (UBC) pTa/pT1 G2 (WHO 1973) compared to classical anatomo-clinical variables using a multidimensional analysis. MATERIALS AND METHODS: A population-based cohort of 213 primary stage UBC (pTa/pT1) G2 (WHO 1973) was evaluated by classic anatomopathological variables and characterized by immunohistochemistry (23 IHC markers, representative of different oncogenic pathways). The most important variables as a predictor of recurrence-free and progression-free survival were selected using multidimensional statistical models, such as random survival forests and least absolute shrinkage and selection operator (. Recurrence and progression-free survival of the previously selected variables were also calculated. RESULTS: Mean follow-up was 58 ± 33.5 months. Recurrence and progression rates were 54.5% (nâ¯=â¯116) and 17,4% (nâ¯=â¯37), respectively. The most influential variables in the low recurrence-free survival were in order: number of resected tumors, high expression of Ki67 (>10%), Cyclin D1 (>10%), and low cytoplasmic staining of p16INK4a. Regarding low progression-free survival, the most important variables were Ki67 (>15%), multicentric tumor arrangement and Survivin nuclear expression (>20%). Kaplan-Meier and cox-regression model analyses showed that the variables selected by multidimensional models were able to discriminate the clinical outcome. CONCLUSIONS: Ki67 index is the most useful IHC marker, since it can improve the prediction of both recurrence and progression-free survival in papillary UBC pTa/pT1 G2 (WHO 1973). There are other markers, whose utility is specific to recurrence-free survival, such as Cyclin D1 and p16INK4a or in progression-free survival, such as Survivin.

OBJECTIVE: To expose the features related to the diagnosis, therapy and follow-up of paratesticular sarcomas, through the presentation of three cases with different histologies. METHODS: Description of the clinical cases, surgical management, and pathological results of the surgical specimens. RESULTS: We present three cases of paratesticular sarcomas, one case being a rhabdomyosarcoma and two liposarcomas. Two patients underwent a single successful surgery, while the third one required a second intervention after recurrence. Today all three patients are free of disease. CONCLUSIONS: Malignant paratesticular sarcomas are infrequent neoplasias in urology. It is essential that the urologist is aware of this possibility when faced with a paratesticular tumor, since radicalness of surgery will be the most decisive factor in the success of the treatment. Adjuvant therapies must be individualized in each case, and the follow-up after surgery should be close, given the poor evolution of these tumors in many cases.

OBJECTIVE: To present the therapeutic management of intractable hematuria secondary to systemic amyloidosis with bladder involvement. METHODS: We describe the clinical case, the medical management, the endo-urological technique used, and the results supported by relevant published literature. RESULTS: A 50-year-old woman with a 20-year history of rheumatoid arthritis in chronic treatment with corticosteroids and non-steroidal anti-inflammatory drugs in addition to chronic renal insufficiency not requiring hemodialysis. Twenty-four hours after resection of a hepatic hydatid cyst she presented intractable hematuria. The ultrasound and CT scan showed the formation of a large blood clot in the bladder not affecting the upper urinary tract. An intra-operative cystoscopy revealed a distended bladder showing signs of inflammation with diffuse, widespread bleeding. Hemostasis was achieved and a biopsy of the mucosa was taken, associated to bladder irrigation with potassium alum as a hemostatic. Given the persistence of the hematuria, further revision in the operating room as well as blood transfusion were carried out and, due to the hemodynamic instability that could not be controlled, finally selective embolization was performed. Intravesical instillation of dimethyl sulphoxide every 72 hours was used to control any remaining hematuria. The biopsy showed bladder amyloidosis. The addition of intravenous steroids and orally administered colchicine successfully controlled the patient's clinical status. CONCLUSIONS: Secondary amyloidosis of the bladder is a condition associated with hematuria that is difficult to manage. Hematuria control is often difficult, requiring aggressive treatment in addition to more conservative approaches.

Prostate cancer (PCa) is the second most common type of cancer among men in Western societies. Once in the castrate-resistant metastatic setting therapeutic options are limited. The importance of angiogenesis in the progression of PCa has been widely reported providing a rationale to test anti-angiogenic compounds for PCa treatment in clinical trials (CTs). However, in spite of the promising results shown in preclinical models and some anti-tumor activity observed in CTs, to date, no angiogenic inhibitor has been approved for use in PCa. This editorial outlines the latest clinical evidence regarding anti-angiogenic therapies in PCa treatment.
