Development and external validation of a highly accurate nomogram for the prediction of perioperative mortality after transurethral resection of the prostate for benign prostatic hyperplasia.
PURPOSE: Benign prostatic hyperplasia affects 60% of men at the age of 60 years. Transurethral resection of the prostate is the gold standard of therapy. We assessed the 30-day mortality rate after transurethral resection of the prostate for benign prostatic hyperplasia, identified risk factors related to 30-day mortality and developed a model that discriminates among individual 30-day mortality risk levels. MATERIALS AND METHODS: We performed development (7,362) and external validation (7,362) of a multivariable logistic regression model predicting the individual probability of 30-day mortality after transurethral resection of the prostate based on an administrative data set (Quebec Health Plan) of 14,724 patients 43 to 99 years old treated between January 1, 1989 and December 31, 2000. RESULTS: Overall 30-day mortality occurred in 58 patients (0.4%) undergoing transurethral resection of the prostate. On univariable analyses increasing age (p
