[Endoscopic treatment of ureterocele in children: is a long term effective technique?].

INTRODUCTION: The endoscopic treatment of the ureterocele is a less invasive procedure. Currently, there are only a few published articles regarding the long-term outcomes of this treatment. MATERIAL AND METHODS: We have introduced this technique in our practice since 1995, and have been tracking 15 pediatric patients for long-term evaluation. RESULTS: The average operative age for endoscopic treatment is 19.40 months (1 week-8 years). In 53% of the cases, the diagnosis was made during prenatal screening. In 27% of the cases, the ureterocele was bilateral, and 47% of the patients have a double system. The indication for endoscopic treatment is 66% ureteric obstruction and 34% vesicoureteric reflux. We perform "uncapping" and incision in the two first cases and puncture in the subsequent procedure. The patients were followed for 4 years (7 months-7 years). During this time, two ureteroceles needed a second perforation, out of the seven that continued having reflux, two were treated with quimioprofilaxis and two were treated endoscopically for anti-reflux. Two patients continued to have reflux, and two were diagnosed with renal atrophy and hemiatrophy. DISCUSSION: The endoscopic treatment avoided an open surgical procedure in almost all cases. The need for anti-reflux puncture occurred in 33% of the cases.

[Cystic angiomatosis].

A case of cystic angiomatosis is presented in a patient whose clinical sign were the presence of an inguinoescrotal mass due to a retroperitoneal lymphangioma, visceral splenic lesions and diffuse skeletal lesions. This rare entity is discussed and a brief review of the literature is made.

[Foreign body aspiration in childhood. Review of 210 cases].

AIM: Foreign body aspiration is one of the accidents with highest incidence, morbidity and mortality in childhood. It is favoured by curiosity and the immature swallowing mechanisms of this age group. To determine the most common signs and symptoms leading to the diagnosis of foreign body aspiration and to demonstrate the diagnostic value of a detailed anamnesis, we analyzed the cases of foreign body aspiration treated in our hospital between 1975 and 1997. MATERIALS AND METHODS: Retrospective study of 210 patients with suspected foreign body aspiration. In 208 patients rigid bronchoscopy was performed. Evidence of a foreign body was found in 90%. RESULTS AND CONCLUSIONS: We emphasize the clinical value of thorough anamnesis which showed high sensitivity (80%) in choking crises and persistent cough. Physical examination and respiratory auscultation showed high sensitivity (90%) but low specificity (16%). Chest X-ray showed the lowest sensitivity with 16% of false negatives. Most foreign bodies were vegetable fragments (82%), with a complication rate of 5.7%. Mortality was 0.9%, with no deaths occurring in the last 8 years.

[Crossed testicular ectopia. Report of a case].

Crossed testicular ectopia is a rare congenital malformation in which both testis are located in the same hemiscrotum, and is related to an anomaly in normal testicular descent. This entity was first described by Lenhossek in 1886 and posteriorly by Halstead in 1907. Since then, there have been described less than a hundred of cases of this rare congenital malformation. Several ethiopathogenic theories have been proposed, including testicular adherence to mullerian structures, fusion of the wolffian ducts or defective gubemacular development, although none of them has been widely accepted. Usually, clinical sign is an inguinal hernia with empty contralateral hemiscrotum, and sometimes both testis in ipsilateral hemiscrotum. A new case of this pathology is presented.

[Congenital lumbar hernia].

Hernias in the lumbar region are abdominal wall defects that appear in two possible locations: the superior lumbar triangle of Grynfelt-Lesshaft and the inferior lumbar triangle of Petit. There are 40 cases reported in the pediatric literature, and only 16 are considered congenital, associated with the lumbocostovertebral syndrome and/or meningomyelocele. A new case is presented. A premature newborn with a mass in the left flank that increases when the patient cries and reduces easily. The complementary studies confirm the diagnosis of lumbar hernia and reveal the presence of lumbocostovertebral syndrome associated. At the time of operation a well defined fascial defect at the superior lumbar triangle of Grynfelt-Lesshaft is primarily closed. The diagnosis of lumbar hernia is not difficult to establish but it is necessary the screening of the lumbocostovertebral syndrome. We recommend the surgical treatment before 12 months of age; the objective is to close the defect primarily or to use prosthetic material if necessary.
