an omental interposition. The exostosis of the symphysis Case report was not removed. Post-operatively the patient recovered with no further complications. Cystography after 2 weeks An 83-year-old man underwent TURP for BPH; 2 weeks later the patient was unable to void and complained of showed no leakage and when the suprapubic catheter was removed, the patient voided normally and was pain in the lower abdomen, fever and that walking was painful. Physical examination showed tenderness over continent. the symphysis pubis that radiated to the perineum and legs. A pelvic X-ray showed an exostosis of the symphysis Comment ( Fig. 1), with reactive sclerosis and superficial bone destruction typical of osteitis pubis. Conservative treat-Osteitis pubis is a painful, non-infectious inflammatory condition that involves the pubic bone and surrounding ment was started, including placement of a transurethral catheter, bedrest and antibiotics. However, the patient structures. It was first described by Beer in 1924 [1] and the aetiology is poorly understood. Osteitis pubis after developed fever, and CT showed an abscess in both adductor muscles (Fig. 2). Cystography revealed a fistula open prostatectomy has been noted previously but only Laroche et al. and recently our clinic have reported between the prostate and the adductor muscles on both sides. The abscess was drained and a transurethral osteitis pubis after TURP [2,3]. In both cases, the TURP was complicated by a prostate-symphysis fistula. In the catheter and ureteric catheters placed. Because of the large exostosis of the symphysis and the impression of case reported by Laroche et al. it was successfully treated conservatively. In the latter case, an operation was this exostosis into the roof of the prostate, conservative treatment was thought unlikely to be successful. necessary and the fistula closed using omental interposition. Osteitis pubis not caused by a prostate-Therefore, 8 weeks after TURP the patient underwent further surgery; at median laparotomy the large defect symphysis fistula has been associated with various urological and gynaecological procedures. The aetiology into the roof of the prostatic urethra was closed using in these cases is still unclear and the treatment is controversial, although mostly conservative. In the two cases we have reported, the patients did not respond to Fig. 1. Pelvic X-ray showing an exostosis of the symphysis (arrow). Fig. 2. CT showing the abscess in both adductor muscles (arrows).
