Effectiveness of Intrarectal Povidone-iodine Cleansing Plus Formalin Disinfection of the Needle Tip in Decreasing Infectious Complications After Transrectal Prostate Biopsy: A Randomized Controlled Trial.

PURPOSE: Prostate biopsy is mostly performed through the transrectal route worldwide and infectious complications may occur in up to 7% of cases. Therefore, alternative strategies to decrease infectious complications are needed. Our aim was to evaluate the effectiveness of intrarectal povidone-iodine cleansing plus formalin disinfection of the needle tip in decreasing infectious complications after transrectal ultrasound guided prostate biopsy. MATERIALS AND METHODS: We conducted a prospective, single-center, phase III trial in patients undergoing transrectal ultrasound guided prostate biopsy randomized 1:1 to rectal mucosa cleansing with gauze soaked in 10% povidone-iodine solution wrapped around the gloved index finger and needle tip disinfection by immersion in a 10% formalin solution before each puncture vs control group. The primary end point was the rate of infectious complications defined as 1 or more of the following events: fever, urinary tract infection, or sepsis. RESULTS: Overall, 633 patients were randomized to the intervention group and 623 to the control group. The infectious complication rate was 3.9% in the intervention group and 6.4% in the control group (RR 0.61; 95% CI 0.36-0.99; P = .049). The rates of sepsis, urinary tract infection, and fever were 0.3% vs 0.5% (P = .646), 2.3% vs 4.1% (P = .071), and 1.3% vs 1.9% (P = .443), respectively. The positive urine culture rate was 5.2% in the intervention group and 9% in the control group (RR 0.57; P = .015). There was no statistically significant difference between the groups regarding the occurrence of noninfectious adverse events. CONCLUSIONS: Intrarectal povidone-iodine cleansing plus formalin disinfection of the biopsy needle tip was associated with a reduction in infectious complications after transrectal prostate biopsy.

Coexistence of prostate neoplasia in patients undergoing radical cystoprostatectomy due to vesical neoplasia

OBJECTIVE: To assess the incidence of bladder carcinoma infiltrating the prostate and prostate adenocarcinoma in patients undergoing radical cystoprostatectomy due to bladder cancer, as well as to assess if the characteristics of the bladder neoplasia influence the prostatic involvement by this neoplasia. MATERIALS AND METHODS: We retrospectively assessed 60 male patients, who underwent radical cystoprostatectomy between July 1997 and December 2003. Mean age was 66.7 years (40 and 93 years). The product of radical cystoprostatectomies was checked for involvement of urethra and prostate parenchyma by the primary neoplasia, and for the presence of associated prostate adenocarcinoma. Bladder neoplasia characteristics, such as localization, size, multifocality, association with in situ carcinoma and histological grade, were studied in order to assess the possibility of using such characteristics as predictive factors of prostate infiltration by bladder urothelial carcinoma. RESULTS: We observed the presence of 20 percent of patients with bladder carcinoma infiltrating the prostatic urethra, 23.3 percent of patients with infiltration of the prostate parenchyma and 28.3 percent of patients with associate prostate adenocarcinoma, resulting in a total of 55 percent of patients with prostatic involvement (infiltrative bladder carcinoma and/or adenocarcinoma). We also observed a statistically significant correlation between tumor location in the trigone, the presence of in situ carcinoma and the histological grade of the bladder tumor with prostatic infiltration by the vesical neoplasia. CONCLUSION: The coexistence of prostatic neoplasia in patients operated for bladder neoplasia was frequent in our sample (55 percent). We observed that the prostatic infiltration by bladder tumors occurs more frequently with tumors located in the trigone, with associated in situ carcinoma and with high histological grade. There was no correlation between neoplastic infiltration of prostate and multifocality or size of the bladder tumor in the studied sample.
