Perinephric hematomas are common after percutaneous needle biopsy of the kidney and are usually clinically occult. Infectious complications in the absence of concomitant urinary tract infection, however, are unusual. A patient is reported who developed perinephric abscess (Streptococcus pneumoniae) at the site of a renal biopsy performed five years earlier. Wisdom tooth impaction and extraction occurred shortly after the biopsy. It is speculated that bacteremia of dental origin plus immunosuppressive therapy acted adjunctively to produce localization of infection in an area of previous trauma. Elective procedures that may induce transient bacteremia after percutaneous kidney biopsy may be hazardous and are best avoided. Antibiotic prophylaxis for such procedures should be considered.
肾周血肿在经皮肾穿刺活检后很常见，通常在临床上不易察觉。然而，在没有合并尿路感染的情况下发生感染并发症并不常见。本文报道了一名患者，在5年前进行肾活检的部位发生了肾周脓肿（肺炎链球菌感染）。活检后不久出现智齿阻生并拔除。据推测，牙源性菌血症加上免疫抑制治疗共同作用，导致感染定位在先前创伤的区域。经皮肾活检后可能诱发短暂菌血症的择期手术可能具有危险性，最好避免。应考虑对此类手术进行抗生素预防。
