    "abstract": "To assess the impact of short-term treatment with cyproterone acetate (CPA) on intraoperative and early postoperative complications of transurethral resection of relatively large prostate.\nWe recruited patients with prostate size of 60-90\u2009g and randomized them into two equal groups. The first one had 50\u2009mg of CPA orally twice a day (bds) for 2 weeks before the operation and maintained it for an extra week postoperatively. The other group received placebo. All patients underwent monopolar transurethral prostatectomy (M-TURP) and the prostatic chips were stained for CD34 specific for nascent blood vessels.\nNinety-five patients were included. Mean patient age was 60.88\u00b12.5 years and mean prostate size was 72.76\u00b17.21\u2009g. CPA was well tolerated with no serious adverse effects. The mean resection time and the mean weight of the resected tissue were comparable between the two groups. Intraoperative blood loss, fluid absorption, and blood loss per gram of resected tissue (259.47\u00b178.27\u2009mL, 787.38\u00b1300.56\u2009mL, and 14.87\u00b14.02\u2009mL/g and 327.25\u00b198.97\u2009mL, 937.4\u00b1350.2\u2009mL, and 17.08\u00b15.55\u2009mL/g, respectively) were significantly lower in the treatment group (p<0.05). In addition, excessive postoperative bleeding was encountered in one case in the treatment group and in seven in the control (p<0.05). Finally, the histopathological study revealed that the mean microvessel density in each of the suburethral portion and the hyperplastic nodules of the prostate was significantly lower in the CPA group (p<0.001).\nThe perioperative use of CPA with M-TURP of a relatively large prostate may help in decreasing the perioperative bleeding and fluid absorption that usually take place during this procedure.",
