[Surgical aspects of open renal biopsy done by urologic residents at Tsukuba University].
The results of the operative aspects of open renal biopsy performed by urologic residents at our University Hospital during the 18 months from July 1982 to December 1983 were analyzed. Open renal biopsy was performed by 1st to 6th year residents for various renal diseases on 19 male and 12 female patients, i.e., 14 patients from Pediatric Department, 16 patients from Nephrologic Department and 1 patient from Urologic Department. All except for 3 operations were done under the guidance of urologic staff. The length of incisional line ranged from 3 to 7 cm (average 5.1 cm) in pediatric patients, and that of nephrologic and urologic patients ranged from 5 to 15 cm (average 8.7 cm). The average operation time was 89.2 minutes for pediatric patients, although it was 81.1 minutes when 1 patient who had concurrently operated on inguinal herniorrhaphy in addition to open renal biopsy was excluded from the analysis. The average operation time was 122.2 minutes for nephrologic and urologic patients, although it was 112.8 minutes when 1 patient who had lost a large amount of blood was excluded. The average blood loss was 28.2 ml for pediatric patients when 2 patients whose blood loss was recorded as "small quantity" was excluded, but it was 24.5 ml when 1 patient who was concurrently operated on for inguinal herniorrhaphy in addition to open renal biopsy was excluded. The average blood loss during operation was 235.1 ml in nephrologic and urologic patients, but it was 149.95 ml when 1 patient who had lost a great deal of blood (1,598 ml) was excluded.(ABSTRACT TRUNCATED AT 250 WORDS)
