Using hyperrealistic simulations to improve digital informed consent for endourological procedures.

OBJECTIVES: To show that digital informed consent (DIC) improves the subjective understanding of information and, therefore, informed consent. PATIENTS AND METHODS: A nonblinded randomized controlled trial was performed in 84 patients who had undergone transurethral resection of bladder, transurethral resection of prostate, or ureterorenoscopy between July 2017 and March 2018. The DIC group watched a hyperrealistic simulation on a tablet device before surgery. After surgery and again 30 days later, both groups completed a validated questionnaire that measured subjective understanding, anxiety, and utility of and need for information. RESULTS: The mean ± SD age of the participants was 68.7 ± 11.1 years. Nine of 84 patients (10.7%) did not complete the questionnaire. A total of 42 patients were allocated to the DIC group and 42 to the control group. The mean ± SD score for immediate subjective understanding in the DIC group was 14.5% higher than in the control group (72% ± 17.5% vs 57.5% ± 23.5%, respectively; P = 0.006). There was no statistical difference in anxiety, utility of and need for information relative to delayed subjective understanding. In subgroup analysis, subjective understanding scores were higher, but not significantly so, among patients with low and higher education levels in the DIC group than in the control group (68% ± 18.1% vs 54% ± 22.5% [P = 0.06] and 76% ± 18.3% vs and 66% ± 21.9%, respectively [P = 0.89]). CONCLUSION: Hyperrealistic simulations improved subjective understanding of information and, therefore, informed consent for endourological procedures.

Epidemiology, Diagnosis and Management of Penile Cancer: Results from the Spanish National Registry of Penile Cancer.

INTRODUCTION: Penile cancer (PC) is a rare malignancy with an overall incidence in Europe of 1/100,000 males/year. In Europe, few studies report the epidemiology, risk factors, clinical presentation, and treatment of PC. The aim of this study is to present an updated outlook on the aforementioned factors of PC in Spain. MATERIALS AND METHODS: A multicentric, retrospective, observational epidemiological study was designed, and patients with a new diagnosis of PC in 2015 were included. Patients were anonymously identified from the Register of Specialized Care Activity of the Ministry of Health of Spain. All Spanish hospitals recruiting patients in 2015 were invited to participate in the present study. We have followed a descriptive narration of the observed data. Continuous and categorical data were reported by median (p25th-p75th range) and absolute and relative frequencies, respectively. The incidence map shows differences between Spanish regions. RESULTS: The incidence of PC in Spain in 2015 was 2.55/100,000 males per year. A total of 586 patients were identified, and 228 patients from 61 hospitals were included in the analysis. A total of 54/61 (88.5%) centers reported ≤ 5 new cases. The patients accessed the urologist for visually-assessed penile lesions (60.5%), mainly localized in the glans (63.6%). Local hygiene, smoking habits, sexual habits, HPV exposure, and history of penile lesions were reported in 48.2%, 59.6%, 25%, 13.2%, and 69.7%. HPV-positive lesions were 18.1% (28.6% HPV-16). The majority of PC was squamous carcinoma (95.2%). PC was ≥cT2 in 45.2% (103/228) cases. At final pathology, PC was ≥pT2 in 51% of patients and ≥pN1 in 17% of cases. The most common local treatment was partial penectomy (46.9% cases). A total of 47/55 (85.5%) inguinal lymphadenectomies were open. Patients with ≥pN1 disease were treated with chemotherapy in 12/39 (40.8%) of cases. CONCLUSIONS: PC incidence is relatively high in Spain compared to other European countries. The risk factors for PC are usually misreported. The diagnosis and management of PC are suboptimal, encouraging the identification of referral centers for PC management.

[Management of chylous fistulas, a rare complication after urologic surgery]. / Manejo de las fístulas de quilo, una rara complicación tras cirugía urológica.

OBJECTIVE: To analyze the different treatments for postoperative chylous fistulae. METHODS: A literature review of the main treatments for postoperative chylous fistula, providing our initial experience of two cases of patients with postsurgical chylorrea, with conservative treatment. RESULTS: There is very limited experience in the treatment of chylous ascites. According to the literature reviewed, Octreotide (somatostatin analogue) can be used, to decrease fistula output. Both our cases cases were treated successfully with subcutaneous octreotide, with drain debit decrease in about 3 days. CONCLUSIONS: The use of octreotide appears to be an effective treatment in the management of chylous fistulae, and it is suggested by some authors as first-line treatment in the management of these, thus decreasing the complications that can appear due to chyle loss.

Extravasación urinaria renal espontánea / Spontaneous renal urinary extravasation

La extravasación espontánea de orina, descrita por Albarrán y publicada por Sole se consideraba como un hallazgo radiológico poco frecuente y la definió en 198 como la salida de orina fuera del tracto urinario en ausencia de trauma, de intervención quirúrgica previa o reciente y tampoco sin antecedente de instrumentación urológica o de urografía excretora practicada con compresión externa. Se presenta a un paciente de 28 años, sin antecedentes de interés, que acudió con cuadro astenia de 1 mes de evolución, asociado a dolor en fosa lumbar izquierda. Que fue estudiado mediante ecografía y tomografía computarizada (TC). Las exploraciones radiológicas identificaron múltiples litiasis en uréter proximal y distal izquierdo. Voluminosa colección de baja densidad rodeando al riñón izquierdo, limitada por la fascia pararrenal sugestiva de urinoma, identificando solución de continuidad en cáliz superior, que se comunica con el urinoma. El tratamiento inicial del paciente fue la colocación de Nefrostomía percutánea de urgencia, para realizar posteriormente, ureteroscopia con ascensión de las litiasis y extracción de estas mediante pielolitotomía abierta. Conclusión: El conocimiento de la clínica y de los hallazgos radiológicos de la extravasación urinaria espontánea por litiasis ureteral en las distintas pruebas de imágenes son cruciales para el manejo de los pacientes afectados por esta infrecuente complicación...

Spontaneous extravasation of urine, described by Albarran and published by Sole was considered a rare radiological finding in 198 and defined as the flow of urine out of the urinary tract in the absence of trauma, previous surgery or recent nor no history of urological instrumentation or excretory urography performed with external compression. We report a patient of 28 years, with no history of interest came with asthenia of 1 month’s duration, associated with pain in left lumbar fossa. That was studied by ultrasound and computed tomography (CT). The radiological identified multiple stones in proximal and distal left ureter. Collection bulky low density surrounding the left kidney limited by suggesting pararenal urinoma fascia, identifying continuity solution upper calyx, which communicates with the urinoma. The patient’s initial treatment was percutaneous nephrostomy placement of urgency for later ascension of the stones with ureteroscopy and removal of these by open pyelolithotomy. The knowledge of the clinical and radiological findings of spontaneous urinary extravasation with ureteral stones in various imaging tests are crucial for the management of patients affected by this rare complication...
