Pubic osteomyelitis following bladder neck surgery using bone anchors: a report of 9 cases.

Abstract

We reviewed 9 cases of pubic osteomyelitis associated with placement of bone anchors for bladder neck suspension procedures for risk factors, bacterial speciation and sensitivities, and interventions performed. Nine women were treated for pubic osteomyelitis following the use of bone anchors for bladder neck suspension surgery. In 8 cases the bone anchors had been placed through a suprapubic incision and in 1 the bone anchors were placed by a vaginal route. Patient ages ranged from 36 to 74 years (mean 51.8). Symptomatic presentation ranged from 2 to 18 months following initial operation. Presenting symptoms included pain over the pubis and/or a draining wound. Staphylococcus species were cultured in all cases, most commonly Staphylococcus epidermidis. Resistance to methicillin was present in 7 cases (78%). Wound débridement and removal of the anchors provided definitive treatment in all but 1 patient, who eventually required partial pubectomy. Pain (3 of 9 cases) and mild incontinence (5 of 9) were present at last followup. Bone anchors used in surgery for urinary incontinence can be associated with pubic osteomyelitis. Infection characteristics are similar to those seen with other urological prosthetic implantation procedures. Aggressive treatment with surgical débridement and long-term antibiotics is usually effective. Staphylococcus species, especially methicillin resistant strains, are the most common bacteria identified in this setting. Careful attention to implantation technique, including appropriate perioperative antibiotic selection, should be considered when using this technique.
