Medical management of benign prostatic hyperplasia.
Medical management of clinical BPH is a reality. The only effective nonsurgical treatment now recommended is aimed at relieving the dynamic component of clinical BPH. Pharmacologic treatment using alpha-adrenoceptor antagonists may be used appropriately to manage patients with prostatism who are poor surgical risks but who could benefit from reduced sympathetic tone. In addition, alpha blockers are used to relieve acute retention, and to prevent retention when increased sympathetic discharge is expected. Thus far, nonsurgical therapy aimed at reducing the mechanical obstruction associated with BPH by prostatic size reduction has failed to produce consistent objective improvement. However, several drugs are now being investigated and may be effective for reducing prostatic size in patients with BPH. Clinical trials are complicated by a number of factors, especially very variable symptoms. Moreover, reduction in prostatic size induced by drugs is not permanent and regrowth occurs with drug withdrawal, necessitating chronic treatment. Ideally, future research should be aimed at the prevention of BPH at an early age. However, this presupposes a better understanding of the pathogenesis of BPH. BPH may not be a single, variable disease but a family of diseases with a number of predictable clinical courses. In the future, we should pay particular attention to histologic variability, to see if in fact different pathologic forms of BPH follow different clinical patterns. If urologists are to keep their predominant position in managing the patient with BPH, they will have to keep informed of medical treatment trials and of potential alternative treatment strategies to prostatectomy.
