Gonadectomía bilateral e histerosgalpingectomía laparoscópica en un adolescente con desorden de desarrollo sexual ovotesticular: reporte de caso / Bilateral gonadectomy and laparoscopic hysterosalpingectomy in an adolescent with ovotesticular disorder of sexual development: case Report

Los desórdenes de desarrollo sexual hacen referencia a niños cuyos genitales al nacer presentan características de ambos sexos o aquellos que, teniendo un fenotipo normal, presentan alteraciones del desarrollo en la pubertad o adolescencia. Estos desórdenes representan un reto diagnóstico y terapéutico, debido a que pueden ser desencadenados por diferentes entidades nosológicas, y por otro lado, pacientes portadores de las mismas patologías pueden presentar diferentes alteraciones anatómicas. La laparoscopia juega un importante papel en el abordaje diagnóstico de estos pacientes; permite la visualización de los genitales internos y la toma de muestras de tejidos para estudios histológicos. Desde el punto de vista terapéutico, la cirugía laparoscópica permite la extirpación de estructuras internas opuestas al sexo definitivo del paciente. Se reporta el caso de un adolescente con desorden del desarrollo sexual ovotesticular (Hermafrodita verdadero) a quien una vez definido el sexo social como varón, se le extirparon a través del abordaje laparoscópico, los remanentes embrionarios derivados del Müller. Se practicó mamoplastia reductora e implantación de prótesis testiculares a través de cirugía convencional.

Disorders of sexual development in adolescents refer to children whose genitals at birth present characteristics of both genders, or to those children with normal phenotype that present a development alteration during puberty or adolescence. These disorders represent diagnostic and therapeutic challenges, because they can be triggered by different nosological entities; and on the other hand, patients carrying the same pathologies can present different anatomical alterations. Laparoscopy plays an important role in the diagnostic approach of these patients because, besides the fact that it allows an excellent visualization of the internal genitals anatomy, it also allows tissue sample taking for histological studies. On the other hand, from a therapeutic point of view, laparoscopic surgery allows removal of internal structures opposed to the patient’s definite gender. We report the case of an adolescent with ovotesticular disorder of sexual development (True Hermaphrodite) from whom, once his male gender was socially defined, the embrionary remnants derived from Müller were removed through laparoscopic approach. Mamoplastic reduction and testicular prosthesis implantation were also practiced through conventional surgery.

[Renal trauma stage IV in a boy treated in a nonoperative form. Report of a clinical case]. / Trauma renal grado IV en un niño tratado en forma no operatoria. Reporte de caso clínico.

The clinical case of a 6 years old boy, who presented severe right renal trauma with rupture of the pyelocaliceal system and renal injury (IV grade), is reported. Upon admittance to emergency he presented paleness, tachycardia, rapid pulse, intense pain in the right lumbar region and macroscopic hematuria. Using abdominal ultrasound scan, an injury of the right renal parenchyma with perirenal collection was shown. Hematology studies showed a decrease in the hemoglobin count of 3,1 g% during the first posttraumatic 48 hours. A non-surgical conservative treatment was decided, since the patient's hemodynamic status held stable despite the hemoglobin alterations. To treat renal injury, a percutaneous catheter drainage was placed in the right perirenal space on day 16th from the accident. The patient was released after this treatment and was controlled as an outpatient, until the rupture of the excretory urinary system was sealed (3 weeks), when the patient returned to have the catheter removed. The patient's progress was excellent, the kidney was preserved and no complications have occurred in a 6 months follow up after the injury. The non-surgical treatment in renal trauma with injury to the excretory system is effective and advisable in children, provided the patients are hemodynamically stable.

Laparoscopic-assisted correction of a retrocaval ureter.

Retrocaval ureter has been traditionally corrected surgically through an open retroperitoneal procedure; however, in recent years, the correction has been accomplished using laparoscopy. The great advantages of this procedure remain limited because of the prolonged time it takes to complete the intracorporeal suture of the ureter, besides the need for a highly experienced surgeon. We present a case in which the ureter was freed using laparoscopy, and the ureteral anastomosis was carried out extracorporeally, which notably diminished the duration of the surgery. This technique would have limited use in obese patients, patients with ureters of limited length, patients with very proximal obstructions of the ureter, and patients with risk of devascularization of both ureteral segments. However, the technique does appear effective and reproducible in adequately selected patients.
