[Small cell carcinoma of the prostate].

Pure small cell carcinoma of the prostate is rare (less than 1% of all prostatic neoplasm). As a result there are few reports in the literature that describe the salient features and appropriate management of this cancer (less than 200 cases reported). Small cell carcinomas of the prostate are a heterogeneous group of tumors, a number of them have neuroendocrine differentiation and are highly aggressive, commonly with visceral metastases at time of diagnosis. Complete temporary remission has been reported with chemotherapy but this tumor has a poor prognosis. The median overall survival from the time of diagnosis is between 5-17.5 months. We report 2 new cases of small cell carcinoma of the prostate and a review of the literature.

[Lasers as an alternative to the endoscopic surgery in BPH].

Neodymium laser (Nd:YAG) has been used for prostatic coagulation. New contact tips have been developed in order to cause vaporization of the prostate. With the objective to examine the effectiveness and safety of 2 new laser procedures. ITT (interstitial thermotherapy) and Sidefocus Technique, in patients with BPH, we have participated in a prospective, international, multicenter study comparing these technique with TURP and prostatic incision. A total of 80 patients suffering from symptomatic BPH in our center were randomized for the four procedures as follow: ITT (18): sidefocus technique (21), incision (20) and TURP (21). Inclusion criteria were at least 50 years old, prostate between 20 and 60 g, maximum peak-flow < or = 12 ml/s, and I-PSS > or = 15. The patient's pretreatment evaluation consisted in World Health Organization symptom score and quality of life, digital rectal examination, transrectal, ultrasound, PSA, urine culture, prostatic biopsy if malignity suspected, uroflowmetric parameters and residual volume. Follow-up was performed using the same pretreatment parameters at one month, three months and six months. Statistical analysis was performed using ANOVA test and Student-Newman-Keul test. Symptom score decreased significantly in all groups. Peak flow rate increase was observed in the four groups but without statistical significance in both laser techniques. Results at the sixth month control comparing peak-flow rates are significantly more favourable for endoscopic surgical techniques (TURP and incision). Other flowmetric parameters, days of hospital stay, duration of catheter drainage, symptom scores and morbidity are analyzed.

[Diagnosis and treatment of renal angiomyolipoma].

Fourteen cases of angiomyolipoma have been diagnosed and treated at our center since it opened 19 years ago. The diagnostic methods and therapeutic approach have changed since then. Noninvasive imaging techniques like CT and ultrasound have significantly enhanced the accuracy of diagnosis. The mode of presentation, number, size and the differential diagnosis may decide between conservative or surgical management of these tumors. A small tumor mass only requires observation. For larger ones, the treatment of choice is preferably by conservative surgery or highly selective embolization if permitted by the severity of the disease. Surgery is warranted when doubt exists on CT and ultrasonography.

[The phenomenon of obstructive uropathy with minimal or no dilatation].

Obstructive anuria does not necessarily show a marked dilatation of the urinary tract on evaluation with imaging techniques. A case with acute renal failure of this type is presented. We discuss why this condition is caused and how diagnosis can be made quickly. Likewise, we discuss the length of time we can defer renal diversion before rupture of the collecting system supervenes and, consequently, urinary extravasation.

[Torsion of the hydatid of Morgagni].

The authors present 6 cases of torsion of Morgagni's hydatid treated in the Emergency Urology Department over a two-year period. They stress the importance of the clinical diagnosis, as well as the differential diagnosis with other "acute, testicular bag" processes, in particular with funicular torsion. Surgical treatment is the only way of overcoming the pain, confirming the diagnosis and preventing the risk of secondary, testicular atrophy.

[Treatment of benign hyperplasia of the prostate using thermal transurethral needle ablation (TUNA)].

Transurethral needle ablation of the prostate (TUNA) is a new, fast and minimally invasive device that produce a selective necrosis of the prostatic gland by delivering low level radiofrequency energy. We describe our experience with this new technique. A total of 42 patients suffering from symptomatic BPH were treated with this procedure. The original generator was used in 27 patients (group 1). A new generator allowing a more homogeneous application of intraprostatic temperature was used in 15 patients (group 2). The patients pretreatment evaluation consisted of World Health Organization symptom score and quality of life, digital rectal examination, uroflowmetric parameters, residual volume, transrectal ultrasound and PSA. Follow-up was performed using the same pretreatment parameters at one month, three months, six months and twelve months. All patients were treated using urethral xylocaine with intravenous or intramuscular sedation (petidine clorhidrate) and tolerance was good. IPSS and quality of life decreased significantly in both groups at first month after treatment and kept low up to twelve-month control. Peak flow rate increased from 7.7 +/- 3.7 ml/sec to 10 +/- 4.1 ml/sec at the twelve-month control in group 1 (p > 0.05), and from 7.6 +/- 2 ml/sec to 9.8 +/- 3.3 ml/sec in group 2 (p > 0.05). Residual volume decrease was statistically significant in group 2 (p < 0.05). No significant complications were encountered. Five patients in group 1 and one patient in group 2 required TURP some time in the follow-up (14%). In our experience, after one year of follow-up, improvement in subjective parameters is evident, although uroflowmetric improvement is moderate and with no statistically significance. No differences were found between both groups of treatment.
