Minimally invasive therapy for benign prostatic hyperplasia: practice patterns in Minnesota.
OBJECTIVE
Benign prostatic hyperplasia (BPH) affects more than 50% of men by the age of 60 and 90% by age 85. Many of these men are not candidates for surgical procedures such as transurethral resection of the prostate (TURP), stimulating the development of less-invasive forms of therapy. We studied the utilization of these newer therapies by urologists practicing in Minnesota.


METHODS
An anonymous questionnaire was sent to 174 members of the Minnesota Urological Society, of which 58 were available for analysis. A case scenario was presented of a patient with BPH refractory to medical therapy. The options were traditional and minimally invasive therapies. The physician was asked to select whether he or she would offer each option and perform the procedure or refer the patient within or outside the practice. Statistical analysis was performed using chi-square and two-sample t-tests on Minitab software. The results were considered significant at P < 0.05.


RESULTS
While 59% of the respondents would offer both minimally invasive and traditional alternatives, 10% would offer only minimally invasive therapy, while 29% would offer only traditional therapy (P = 0.01). The most common minimally invasive therapies offered were transurethral microwave thermotherapy and (55%) and transurethral needle ablation (33%). If they offered a form of minimally invasive therapy, the majority of respondents would perform the procedure themselves. Rural urologists were less likely to offer minimally invasive therapy (43%) than metro physicians (81%; P = 0.035). There was no significant difference in the use of minimally invasive therapies by rural and urban urologists (P = 0.409) or urban and metropolitan urologists (P = 0.119). Urologists completing their training between 1960 and 1980 were less likely to offer minimally invasive therapy. There was no significant difference in the likelihood of offering traditional versus minimally invasive alternatives according to the percent of managed care in the practice.


CONCLUSIONS
Urologists closer to the completion of their residency training are more likely to include a minimally invasive technique in their treatment plan, while urologists practicing in rural Minnesota are less likely to offer minimally invasive procedures. Further emphasis should be placed on increasing the availability of minimally invasive techniques in rural settings.
