Ureterocele. Nuestra experiencia con 61 casos, en 23 años en el Hospital del Niño / Ureterocele. Our experience with 61 cases, in 23 years at the Hospital del Niño

Different surgical treatments for the ureteroceles were reviewed, but their comparison is difficult. Frequently the results are different, due to the type of patients treated, the different techniques and the recovery criteria used. We present and analyze the results in 61 patients treated during 23 years at the Children's Hospital in Panama City. 25% of our cases were reoperated (statistically acceptable). There is not one surgical technique for all cases. Each one has to be treated according to the type of lesion they present

[Bilateral Wilms' tumor. Current treatment]. / El tumor de Wilms bilateral. Tratamiento actual.

Partial nephrectomy combined with chemotherapy has been the most effective treatment in bilateral Wilms tumors. We present two cases. The bilateral synchronous tumor are present in 4.2% and the metachronous tumor in 1.6%, in the world statistics. The synchronous bilateral Wilms tumor, Stage V, have an excellent prognosis: over 87% survival, compared to 40% of the metachronous bilateral Wilms tumors.

Uréter ectópico: nuestra experiencia en el Hospital del Nino de Panamá 1973-1995 / Ectopic ureter: our experience at the Children's Hospital of Panamá 1973-1995

The author reports 12 girls, 4 to 8 years of age, and 2 boys, a newborn and a 6 year old, with ectopic ureter diagnosed at the Children's Hospital in Panama City. In 7 of the girls the ureter drained into the vaginal vestibule and in 5, into the urethra. In the boys, the ureter drained into the prostatic urethra in one and in the perineal region in the other. All the patients had had incontinence and urinary tract infection. The author present the clinical history of a 3 year old girl with the diagnosis of right renal agenesis, absence of the right ureteral meatus and urinary incontinence, in whom resection of the hypoplastic, dysplastic right kidney and the atretic right renal artery was done. The distal ureterogram, performed during the operation, showed drainage into a Gartner's cyst (residual of a Wolff's cyst) which then drained into the vagina

[Laparoscopic pelvic lymphadenectomy in patients with cancer of the prostate]. / Linfadenectomía pélvica laparoscópica en pacientes con cáncer de próstata.

Laparoscopic pelvic lymphadenectomy is a new procedure to determine the propagation grade of Prostatic adenoma and the treatment to recommend. It is a satisfactory procedure for the diagnosis, with minimal morbidity. It is described our early experience in Panama, 6 patients and 51 lymph nodes removed.

[A preliminary report on penile cancer in the Instituto Oncológico Nacional from 1982 to 1990]. / Informe preliminar de cáncer del pene en el Instituto Oncológico Nacional de 1982 a 1990.

Cancer of the penis is not to common disease and its incidence varies between 0.5 and 5%. In Panama, 70 cases were registered from 1982 to 1990 and it is considered an important social problem in the rural population. Phimosis and poor hygiene are important factors in its etiology. Of 70 cases seen at the National Institute of Oncology from 1982 to 1990, 51 cases were analyzed comparing two approaches in regard to lymph node metastasis: (1) an expectant approach in those without clinically suspected lymph node metastasis, and (2) lymph node biopsy using the Cabañas technique in those clinically suspected followed by lymphadenectomy if the biopsy was positive. The high percentage biopsies (Cabañas technique) as well as the significant morbidity (31.6%) in these patients, compared with no morbidity and the high accuracy of the expectant approach (90%) lead the authors to recommend the Cabañas biopsy technique only for patients of low educational level and difficult follow-up as outpatients. Others patients should be followed clinically for signs of tumor activity.
