Factors influencing post-operative hospital stay after transurethral resection of the prostate gland.

The influence of 12 clinical and social factors on the length of post-operative stay in hospital after transurethral resection of the prostate was investigated in 100 patients. Using a multiple binary regression analysis, the factors significantly associated with a post-operative stay exceeding 6 days were: patient's age greater than 70 years (P less than 0.005), the presence of existing cardiovascular disease (P less than 0.005) and the weight of the prostate gland resected greater than 10 g (P less than 0.005). The first two factors are useful in providing a prediction of prolonged post-operative stay. The results indicate that those factors associated with a prolonged post-operative stay are beyond the control of the clinician.
