The effect of rectal Foley catheterization on rectal bleeding rates after transrectal ultrasound-guided prostate...

To assess whether Foley catheterization of the rectum after transrectal ultrasound (TRUS)-guided prostate biopsy decreases complication rates.

Between June 2000 and September 2006, 275 consecutive patients were evaluated after undergoing TRUS-guided prostate biopsy. All procedures were performed on an outpatient basis. Patients were divided into two groups. In the first group (n = 134), a Foley catheter was inserted into the rectum and inflated to 50 cm(3) after TRUS-guided biopsy. In the second group (n = 141), catheterization was performed without balloon placement. Rectal bleeding, hematuria, hematospermia, infection, and acute urinary retention rates were compared between groups.

The mean ages of the patients were 63.3 years +/- 5.6 and 62.1 years +/- 7.2 years in the Foley catheter group and control group, respectively (P = .112). Hematuria, hematospermia, infection, and rectal bleeding occurred in 31 (23.1%), 30 (22.4), nine (6.7%), and two patients (1.5%), respectively, in the Foley catheter group; and in 36 (25.5%), 36 (25.5%), 11 (7.8%), and 25 patients (17.7%), respectively, in the control group. The incidences of infection, hematuria, and hematospermia were not significantly different between groups (P > .05). In contrast, the rectal bleeding rate was significantly lower in the Foley catheter group (1.5%) than in the control group (17.7%; P = .001).

Although it has no effect on other complications, TRUS-guided prostate biopsy with rectal Foley catheterization is a useful, practical method to decrease or prevent rectal bleeding.
