[Biochemical recurrence in patients with prostate cancer after radical treatment. Comparative study of prostatectomy vs. radiotherapy].

Objectives: To compare the biochemical relapse-free survival between radical prostatectomy and radiotherapy in patients with localized prostate cancer of low and intermediate recurrence risk.

Methods: A retrospective study of 435 patients with localized prostate cancer, radical prostatectomy was performed in 65% of patients and radiotherapy was in 35%. The Kaplan-Meier Estimator was used to assess the biochemical relapse-free survival and long-rank test, Breslow and Tarone-Ware to evaluate the differences between the groups with confidence intervals at 95%.

Cadaver donor kidney retransplantation in the pediatric patient: complications and long-term outcome.

Purpose: We compared the outcome of second and third kidney allografts with that of the first kidney allograft in pediatric recipients.

Materials And Methods: We classified 173 cadaveric kidney recipients into 2 groups. Group 1 comprised 120 first transplants and group 2 comprised 53 retransplants, including 43 second and 10 third transplants.

[Neurourological characterization of myelomeningocele in the adult patient].

Objectives: To characterize the neurourological features of the vesicourethral dysfunction of patients with cogenital myelomeningocele when they reach the adult age.

Methods: We report the results of the neurourological physical examination and video urodynamic tests of 52 adult patients born with myelomeningocele, with ages ranging from 18 to 14 years (mean age 20.7) controlled over the last 14 years in the Urodynamics Unit of the Hospital Gregorio Morañon in Madrid.

[Prostate cancer and transrectal ultrasound].

We describe the ultrasonographic changes prostate cancer can produce, and analyze the usefulness of ultrasonography in the study of this disease. Transrectal ultrasound does not have enough sensitivity and specificity for the diagnosis, metastasic study, and diagnosis of recurrences after radical prostatectomy. Nevertheless the ultrasound study of the morphology of the prostatic apex may be useful for the planning and performance of the apex dissection during radical prostatectomy.

[Results of the use of donors under 3 years of age for pediatric renal transplantation].

Objectives: To evaluate the functional results and incidence of complications in a series of pediatric renal transplants using grafts from pediatric donors under 3 years of age.

Methods: We review a serious of 19 renal transplants consecutively performed in pediatric receptors with donors under the age of 3 years. We analyze immediate function, medical and surgical complications, and long and mid-term graft and patient survivals.

[Relation of age and prostatic volume to cancer detection in prostatic biopsies from patients with non-suspect rectal palpation].

Objectives: To evaluate which clinical variables are predictive for prostate cancer and possible relationships among them, in patients with elevated PSA and non suspicious digital rectal examination (DRE) undergoing first prostate biopsy.

Methods: 1618 patients with elevated PSA and non suspicious DRE who underwent sextant peripheral prostate biopsy were selected from our database. PSA, age, prostate volume, and detectable nodule by ultrasound were selected as variables related to cancer detection in first and second biopsies.
