[The study of renal safety in elderly patients with benign prostatic hyperplasia treated with α receptor blockers]

Objective: To investigate the renal safety in patients with benign prostatic hyperplasia treated with tamsulosin hydrochloride. Methods: A retrospective analysis of 10 cases of patients, who had renal dysfunction after treatment with long-term tamsulosin hydrochloride. Results: The average duration of oral medicine was 2 to 24 months with an average of 7.2 months. The serum creatinine after discontinuation of tamsulosin hydrochloride decreased from 132.5 μmol/L (100-208 μmol/L, normal 59-104 μmol/L) to 95.7 μmol/L (73-122 μmol/L, normal: 59-104 μmol/L) (F=10.385, P=0.000). Conclusion: Preliminary results show that taking tamsulosin hydrochloride might lead to renal damage in old patients with benign prostatic hyperplasia. Safety is the premise, and the right medicine should be chosen for different side effects in order to protect the safety of patient.
