Complication of transurethral prostatic resection is hemorrhage, water intoxication, urethral stricture, perforation of bladder neck and surgical capsule, urinary incontinence . and infection. Hemorrhage is the most usual complication of TURP. Measurement of blood loss during TURP is very difficult because of dilution of blood with irrigating fluid and is very important to management of patient during and after surgery because its objectives are elderly patient.
We studied the blood loss during TURP in 41 patients from Jan., 1984 to June, 1985, but 6patients were excluded because blood transfusion was performed during TURP by recognition of massive blood loss. Blood loss was measured in 35 cases by spectrophotometer used benzidine-heme color reaction.
Following results were obtained.
1. Blood loss during TURP per time was 329+-241 ml (Mean +- S.D.)
2. Resection time was 71+21 min (Mean +- S.D.) and blood loss per minute was 4.61 ml. Correlation coefficient between resection time and blood loss was +0.12 and was not significant.
3. Resected prostatic chip weight was 17.6+- 7.3 gm(Mean +-S.D.) and blood loss per gram was 18.7 ml. Correlation coefficient between resected weight and lood loss was +0.29 and was significant weakly.
4. Irrigation fluid was used 22.2+8.l L (Mean +-S.D.) and blood loss per liter was 14.8ml. Correlation coefficient between irrigation fluid and blood loss was +0.32 and was significant weakly.
