Renal biopsy is usually performed as an in-patient procedure, with patients having to be confined to bed for about 24 hours of observation after the procedure. In an attempt to reduce avoidable hospital bills, renal biopsy as a day procedure was evaluated prospectively in 20 (8 M, 12 F) selected nephrotic patients who required renal biopsy to establish tissue diagnosis. They were all normotensive with no evidence of significant renal impairment and aged 21.5+/-2.9 years (range: 17-25). All biopsies were carried out in the morning and patients observed for a mean duration of 9.6+/-0.8 hours (range 8.5-10.5) before discharge, and seen again on outpatient basis within 48 hours of discharge from hospital. Adequate renal tissue was obtained from each of the patients, with a mean core length of 1.28+/-0.5 cm (0.5-1.75) and mean number of glomeruli per section of 10.1+/-4.8 (6-21). The mean number of passes made to obtain renal tissue was 1.7+/-0.4 (1-2). No macroscopic hematuria or significant complications occurred during the Post-OP observation period. It does appear that in carefully selected cases, renal biopsy can be safely performed as a day procedure without compromising adequacy of tissue obtained, while saving the enormous cost usually associated with prolonged observation period, Post-biopsy.
肾活检通常作为住院手术进行，术后患者必须卧床观察约24小时。为了减少不必要的住院费用，对20例（8例男性，12例女性）需要进行肾活检以明确组织诊断的肾病患者进行了前瞻性评估，将肾活检作为日间手术。他们血压均正常，无明显肾功能损害证据，年龄为21.5±2.9岁（范围：17 - 25岁）。所有活检均在上午进行，患者在出院前平均观察9.6±0.8小时（范围8.5 - 10.5小时），并在出院后48小时内进行门诊复查。每位患者均获得了足够的肾组织，平均活检组织长度为1.28±0.5厘米（0.5 - 1.75厘米），每切片平均肾小球数为10.1±4.8个（6 - 21个）。获取肾组织的平均穿刺次数为1.7±0.4次（1 - 2次）。术后观察期间未发生肉眼血尿或严重并发症。在经过精心挑选的病例中，肾活检似乎可以安全地作为日间手术进行，而不会影响所获组织的充足性，同时还能节省通常与活检后长时间观察相关的巨额费用。
