Curva de aprendizaje de la ecografía renal en una unidad docente pluriprofesional / Renal ultrasound learning curve performed in a multiprofessional teaching unit

Introducción: El objetivo de esta experiencia fue analizar un módulo formativo inserto en la práctica asistencial de un departamento de urología con la participación de enfermeras especializadas en ecografía urológica como monitoras. Material y métodos: Participaron en el estudio 12 estudiantes de medicina carentes de cualquier conocimiento de ultrasonografía. Su formación corrió a cargo de dos enfermeras con gran experiencia en ecografía. Después de dos sesiones de entrenamiento, se analizó la concordancia entre sus hallazgos en la exploración de los riñones y los de un urólogo especialista. Para analizar la experiencia desde todos los puntos de vista, se exploró el grado de aceptación del módulo formativo por parte de los usuarios y la tolerancia de los profesionales involucrados en términos de síndrome de desgaste profesional (SDP). Por último, se calcularon los costes. Resultados: El coeficiente kappa de concordancia entre el experto y los estudiantes fue bueno (≥ 0,67) en el 58,3% de los casos. No se detectaron rasgos de SDP entre los involucrados en la experiencia. La participación de las enfermeras como monitoras redujo el coste del operativo en un 25% en comparación con los costes en los que se podría haber incurrido caso de docentes urólogos senior. Conclusiones: Las enfermeras pueden proporcionar los rudimentos de la formación en ecografía a legos en la materia. La exploración de individuos con cálculos renales o ureterohidronefrosis se traduce en una mayor concordancia entre observadores. El usuario involucrado acepta de buen grado la experiencia. El operativo resulta inocuo para el personal participante.

Introduction: The objective of this experience was to analyze a training module inserted in the care practice of an urology department, with the participation of nurses specialized in urological ultrasound as monitors. Material and methods: Twelve medical students with no knowledge of ultrasonography participated in the study. His training was carried out by two nurses with extensive experience in ultrasound. After two training sessions, the agreement between their kidney examination findings and those of a specialist urologist was analyzed. To analyze the experience from all points of view, the degree of acceptance of the training module by the users was explored, as well as the tolerance of the professionals involved in terms of professional burnout syndrome (PBS). Finally, the costs of the operation were calculated. Results: The kappa coefficient of agreement between the expert and the students was good (≥ 0.67) in 58.3% of the cases. No traits of PBS were detected among involved in the experience. The participation of nurses as monitors reduced the cost of the operation by 25% compared to the costs that could have been incurred if they had been senior urologist teachers. Conclusions: Nurses can provide the rudiments of sonography training to laymen. Examination of individuals with kidney stones or ureterohydronephrosis results in greater interobserver agreement. In general, the user involved willingly accepts the experience. The operation is harmless for the participating staff.

A prospective randomized study comparing bipolar plasmakinetic transurethral resection of the prostate and monopolar transurethral resection of the prostate for the treatment of Benign Prostatic Hyperplasia: efficacy, sexual function, Quality of Life, and complications

ABSTRACT Objective: To generate high-quality data comparing the clinical efficacy and safety profile between monopolar transurethral resection of the prostate (M-TURP) and bipolar plasmakinetic resection of the prostate (PK-TURP) for benign prostatic hyperplasia (BPH). Materials and Methods: Prospective, randomized, single-blinded study conducted in a tertiary-care public institution (Dec/2014-Aug/2016). Inclusion criteria: prostate of <80g in patients with drug-refractory lower urinary tract symptoms (LUTS), complications derived from BPH, or both. Exclusion criteria: a history of pelvic surgery/radiotherapy, neurogenic bladder dysfunction or documented/suspected prostate carcinoma. Treatment efficacy evaluated at 1, 3, 6 and 12 months. Efficacy outcomes: international prostate symptom score (IPSS), quality-of-life (QoL) score, international index of erectile function-5 (IIEF-5), maximum urinary flow rate (Qmax), postvoid residual urine (PVRU) volume, and prostate volume (PV). Complications and sequelae also assessed. Comparisons performed with parametric/non-parametric tests. Results: Out of the 100 hundred patients, 84 qualified for the analysis (45 M-TURP/39 PK-TURP). No significant differences found in baseline characteristics or operative data, except for a longer operative time in PK-TURP (MD:7.9min; 95%CI:0.13-15.74; p=0.04). No differences found in IPSS, Qmax or PVRU volume. QoL score at 12 months was higher in PK-TURP (MD:0,9points; 95%CI:0.18-1.64; p=0.01). No differences in sexual function, PV, complications or sequelae were found. This study is "rigorous" (Jadadscale) and has a low risk of bias (Cochrane-Handbook). Conclusions: Based on this controlled trial, there is not significant variation in effectiveness and safety between M-TURP and PK-TURP for the treatment of BPH. The small difference in QoL between PK-TURP and M-TURP at the one-year follow-up is not perceivable by the patients and, therefore, not clinically relevant.

Priapismo de alto flujo postraumático en paciente pediátrico tratado con embolización arterial selectiva / Postraumatic high-flow priapism in pediatric patient treated with selective arterial embolization

El priapismo arterial es una rara patología en pacientes pediátricos, originada por una fístula entre la arteria cavernosa y los sinusoides del cuerpo cavernoso, habitualmente secundaria a un traumatismo perineal. Presentamos el caso de un varón de 16 años con priapismo arterial de 5 días de evolución tras una caída a horcajadas, tratado satisfactoriamente mediante embolización arterial supraselectiva con material reabsorbible. Seis meses después, el paciente presenta detumescencia completa sin disfunción eréctil asociada. La embolización arterial en pacientes pediátricos es compleja debido al menor calibre arterial y la necesidad de control de la arteria pudenda interna contralateral para evitar el desarrollo de complicaciones. La utilización de material reabsorbible permite disminuir el riesgo de disfunción eréctil posterior y, aunque presenta un mayor índice de recurrencias, constituye una alternativa eficaz en el tratamiento de esta patología.

Arterial priapism is a rare condition in pediatric patients, caused by a fistula between the cavernous artery and the sinusoids of the corpus cavernosum, usually secondary to perineal trauma. We report the case of a 16 year old child with arterial priapism of 5 days duration following a fall astride, successfully treated by superselective arterial embolization with absorbable material. Six months later the patient had complete detumescence without secondary erectile dysfunction. Arterial embolization in pediatric patients is complex due to the smaller arterial size and the need to control the contralateral internal pudendal artery to prevent the development of complications. The use of absorbable material helps reduce the risk of subsequent erectile dysfunction and, although it has a higher rate of recurrence, is an alternative for the treatment of this pathology.
