Sonablate-500 transrectal high-intensity focused ultrasound (HIFU) for benign prostatic hyperplasia patients / 华中科技大学学报（医学）（英德文版）

To evaluate the safety and efficacy of transrectal high-intensity focused ultrasound (HIFU) in the treatment of benign prostatic hyperplasia (BPH), serial studies were conducted in 150 BPH patients before and 30 min, 1, 2, 6 and 12 month(s) after Sonablate-500 HIFU treatment. A silicon-coated indwelling 16F latex catheter was placed during the determination of the therapy zone. Preoperative and postoperative evaluations were made by using the international prostate symptom score (IPSS), quality of life (QOL), uroflowmetric findings and transrectal ultrasound, and incidence of complications. The cystourethrography was done in 23 patients within 1 year postoperatively. The results showed that after HIFU treatment, IPSS and QOL scores were significantly decreased at 1, 2, 6 and 12 month(s) (P<0.01). Maximum urine flow rate (6.0 to 17.2 mL/s, P<0.01), PVR (75.0 to 30.3, P<0.01) and prostatic volume (65.0 to 38.1 mL, P<0.05) were significantly improved 12 months after the operation. Recurrent urinary retention (n=2) and urethrorectal fistula (n=1) occurred at the 15(th) postoperative day. The duration of the HIFU prostate ablation was 25-90 min. The mean time for an indwelling catheter was 3-19 days. These data demonstrate that treatment of BPH with Sonablate-500 HIFU is safe and effective.

Complicaciones en biopsia prostática transrectal ecoguiada / Complications in transrectal ultrasound guided prostate biopsy

En la detección precoz del cáncer prostático se incorpora la ecotomografía transrectal como un examen tanto diagnóstico como orientador para realizar la biopsia prostática. Evaluamos las complicaciones ocurridas en el estudio retrospectivo de una serie de 381 biopsias, efectuadas en el período agosto de1995 y julio de 2002. Observamos 14 complicaciones, 3,67 porciento, siendo lo más relevante 6 casos de sepsis, 5 casos de fiebre alta y 2 casos de sangramiento mayor, rectorragia y uretrorragia, todos resueltos satisfactoriamente con nuestros protocolos terapéuticos. Los cuadros sépticos y febriles constituyen complicaciones serias y requieren modificaciones en su profilaxis.
