[Usefulness of free prostate specific antigen in the detection of prostate cancer].

Background: The predictive value of prostate specific antigen for prostate cancer, when levels are between 4 and 10 ng/ml, is low. Within these range of values, some authors recommend the measurement of the free fraction of the antigen to improve its predictive capacity.

Aim: To evaluate the predictive value of the free fraction in subjects with prostate specific antigen values between 4 and 10 ng/ml.

[Neodymium YAG laser in treating prostatic adenoma].

Background: Conventional surgery and transurethral ablation are the treatments of choice for benign prostatic hyperplasia.

Aim: To report our experience with Neodynium: YAG laser ablation of prostatic adenomas.

Patients And Methods: 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.

[Microwave transurethral thermotherapy in the treatment of prostatic adenoma].

We report 195 patients with prostatic adenoma treated with microwave transurethral thermotherapy. All patients were initially subjected to a clinical assessment including Madsen-Iversen symptom score, digital rectal examination, measurement of urine flow rate and residual urine volume, transrectal prostatic ultrasound examination and blood prostate specific antigen determination. A prostatron machine was used, installing an urethral probe under local anesthesia.

[Laparoscopic lumboaortic retroperitoneal lymphadenectomy in testicular neoplasm].

Lumboaortic lymphadenectomy is a therapeutic alternative for patients with nonseminomatous testis tumors and its principal untoward effect is the loss of ejaculation. The anatomic knowledge of lymph node metastasis allows lower limit definition of aortic dissection, maintaining the diagnostic sensitivity and ejaculation. We report three patients with nonseminomatous testis tumors subjected to a reduced video-laparoscopic lumboaortic lymphadenectomy.
