title: [Investigation of resection and coagulation times during transurethral resection of the prostate among operators determined using a time-measuring instrument].
abstract: We investigated resection and coagulation times for 123 patients with lower urinary tract symptoms suggestive of benign prostatic hyperplasia who underwent transurethral resection of the prostate (TUR-P) and their differences among surgeons. The numbers of cases of TUR-P in this study were 57 for Doctor A (experienced about 4000 cases), 60 for Doctor B (experienced about 100 cases) and 6 for a visiting physician (experienced about 50 cases). We measured resection and coagulation times by turning on a time-measuring instrument that was made using commercially available parts. There were significant differences in entire operation time, and operation, resection and coagulation times per resected weight of the tissue among the 3 doctors (Doctor A < Doctor B < visiting physician, p < 0.0001, Kruskal-Wallis test). The percentage of total operation time accounted for by resection time and coagulation time in TUR-P was 37% for doctor A, whereas it was 27% for doctor B and that for the visiting physician was 21% (p < 0.0001, Kruskal-Wallis test). Thus, for doctors with more experience resection time and coagulation time accounted for higher percentages of total operation time. The measuring instrument is inexpensive and has the potential to be a useful tool for checking a surgeon's skill.
