Penetration of ampicillin and sulbactam into human epididymis and testis
Summary Urologic refertilization microsurgery such as vaso-vasostomy or vaso-epididy-mostomy benefits from perioperative antibiotic prophylaxis. The ability of ampicillin and sulbactam to penetrate sufficiently into mixed epididymis or testis tissue was investigated in nine patients (bodyweights ranged from 58 kg to 92 kg, mean 77.3 kg) undergoing orchiectomy for testicular cancer or advanced prostatic cancer. Each patient received a single infusion of 3 g ampicillin/sulbactam (ratio 2 : 1) preoperatively for antibiotic prophylaxis. The concentrations of both components were determined in serum and in epididymis/testis tissue samples taken 30 min to 65 min after infusion. Ampicillin was determined by bioassay and sulbactam was determined by gas chromatography/mass spectrometry. Mean tissue concentrations of ampicillin were 38.5±15.9 mg/kg. Mean tissue concentrations of sulbactam at the same time were 19.8±5.2 mg/kg. Comparison of the tissue/serum ratios for both agents showed no significant difference. These values indicate that both compounds achieve high concentrations in the scrotal organs. The concentrations exceed the MIC (minimal inhibitory concentration) values of important bacterial pathogens such asStaphylococcus aureus involved in postoperative wound infections. The combination of ampicillin and sulbactam may be effective for perioperative prophylaxis in reconstructive scrotal urologic surgery..
