RESUMO

In this manuscript, the surgical technique step by step (ten easy steps) and current indications of radical perineal prostatectomy will be described. The procedure is not recommended if the patient has preexisting conditions that make a lithotomy position unwise in which case the retropubic approach should be utilized. An understanding of the anatomy of the different fascia layers surrounding the prostate gland and seminal vesicle and their relationship to the rectum and other pertinent structures is extremely germane to any study of radical perineal prostatectomy. Furthermore, attempts at potency-sparing prostatectomy are facilitated by accurate knowledge of the course of the neurovascular bundles. Step - 1 - Skin incision: The patient is placed in exaggerated dorso-lithotomy position with the perineum parallel to the floor. An inverted U-shape incision is marked medial to the ischial tuberosities outside to the external anal sphincter. Step - 2 Development of the ischiorectal fossa. Development of the ischiorectal just medial to the ischial tuberosities. Step - 3 Division of central perineal tendon. By inserting finger into both ischiorectal fossa and palpating medially, one can feel the rectal sheath and location of the rectum. Step - 4: Division of the rectourethralis muscle. By dividing this muscle one will be able to separate the rectum from Denonvilliers' fascia of muscle fiber tissue present. Step - 5: Ligation of vascular pedicles. The lateral pedicles can be visualized and palpated as a bundle of tissue lateral to the seminal vesicles. The prostate is further mobilized laterally by blunted dissection. Step - 6: Division of urethra: Meticulous urethral division will ensure an adequate vesico-urethral anastomosis later in the procedure...

RESUMO

Conventional surgery and transurethral ablation are the treatments of choice for benign hyperplasia. To report our experience with Neodymium YAG laser ablation of prostatic adenomas. Revision of 182 patients subjected to Laser ablation of benign prostatic adenoma of whom 28 had a complete urinary retention and 50 were considered of high surgical risk. One hundred eighty patients had spontaneous voiding after surgery, there were no intraoperatory complications and were discharged 6 to 24 hours after the procedure. Urinary flow increased from 8 ml/sec in the preoperative period to 20 and 21 ml/sec, two and six months after surgery. Symptom score decreased from 12 to 1.2 points. Seven patients had late hematuria and two required vesical lavage and cytoscopic clot drainage. Ten patients had a positive urine culture, 12 had lack of ejaculation and 75 percent had some degree of dysuria. Neodymium Yag laser ablation of benign prostatic adenoma seems to be efficient and safe

RESUMO

Veinticinco lactantes que presentaron vómitos fueron examinados ultrasonográficamente en un lapso de 13 meses: de Abril de 1986 a Mayo de 1987 en la Unidad de Gastroenterología de San Felipe. En 10 de ellos se detectó por ultrasonidos, una masa hipoecoica cerca de la vesícula y anterior al riñón derecho; dicha masa medía desde 1 cm hasta 3 cm de diámetro, con un promedio de 1.5 cm. La imagen ecográfica caracterizada por un anillo hipoecogénico central, fue interpretada como la masa muscular hipertrofiada en la estenosis pilórica. A los 24 lactantes se les practicó ultrasonido abdominal y radiología del tracto gastrointestinal superior, bajo control fluoroscópico, para comparar los resultados finales entre si y con el diagnóstico post-operatorio, en los casos que ameritaron intervención quirúrgica. En 10 casos, el diagnóstico ecográfico fue positivo para estenosis pilórica hipertrófica congénita (EPHC) y 14 fueron reportados ecográficamente normales. De los 10 pacientes con diagnóstico ultrasonográfico de EPHC, 9 fueron confirmados radiológica y quirúrgicamente y el caso restante, que presentó duda radiológica por permitir paso de contraste a intestino y simultánea mejoría clínica, fue posteriormente confirmado quirúrgicamente, como EPCH. De los 14 casos reportados ecográficamente normales, 10 presentaron reflujo gastro-esofágico radiológico, y en 4 casos restantes, la radiología fue normal. De todo lo anterior se deduce, que ultrasonido debe ser usado como método de primera elección para el diagnóstico de EPCH, ya que su exactitud muestra una efectividad diagnótica de 100 por ciento, además, es sencillo, rápido, de bajo costo, no utiliza radiaciones ionizantes, evita el peligro de aspiración de Bario y especialmente, porque ofrece la ventaja de un diagnóstico precoz
