Psoas Abscess and Discitis after Intradiscal Nucleoplasty / 대한마취과학회지

Nucleoplasty is a newly developed minimal invasive spinal surgery using a coblation technique. The complications of this new spinal surgery are trauma to retroperitoneal organs involving the kidney, discitis, menigitis, and epidural abscess. Recently, postoperative psoas abscess and discitis appears to have increased in frequency, in part because procedures performed on the spine have been more frequent and improvements in diagnostic capabilities have been made. Antibiotic therapy, abscess drainage, or a surgical procedure is required to treat discitis and psoas abscess. We encountered one case of postoperative psoas abscess and discitis after a nucleoplasty that had not responded to antibiotics but which responded successfully to treatment by spinal surgery.

Relationship between Nocturnal Polyuria and Antidiuretic Hormone in Chronic Spinal Cord Injury

OBJECTIVE: To delineate the role of antidiuretic hormone (ADH) in relation to nocturnal polyuria, and to identify the factors influencing on the diurnal antidiuretic hormone level. METHOD: The ADH was measured by radioimmuoassay at daytime (2:00 PM) and at nighttime (2:00 AM) with nocturnal polyuria group (11) and without nocturnal polyuria group (8). Urine volume, serum osmolarity, urine osmolarity, and blood pressure were also measured at the same time. RESULTS: 1) The ADH at 2:00 AM did not increase in nocturnal polyuria group, although it increased in no-symptom group. 2) There was a statistically significant correlation between wheelchair ambulation time and daytime ADH level. 3) The difference of ADH level between daytime and nighttime showed decrease in orthostatic hypotension group. CONCLUSION: There was relationship between nocturnal polyuria and diurnal variation of ADH level. The ADH concentration seems to be influenced by the postural factors and sympathetic factors.
