Inguinal hernias in men undergoing open radical retropubic prostatectomy.
OBJECTIVE
To determine the incidence of inguinal hernias in men undergoing open radical retropubic prostatectomy (RRP).


METHODS
The incidence of preoperative and postprostatectomy inguinal hernias were determined by a retrospective chart review and questionnaire survey of 1130 consecutive men who underwent open RRP by a single surgeon from October 2000 to October 2005. A preoperative inguinal hernia was diagnosed by the physical examination or abdominal computed tomography findings. The incidence of new postoperative hernias was ascertained by the patients' responses to a survey indicating the development of a new groin bulge or hernia.


RESULTS
Of the 1130 patients, 146 (13%) had a preoperative inguinal hernia. Increasing age and lower body mass index were significantly associated with the detection of a preoperative inguinal hernia. The sensitivity of detecting an inguinal hernia by physical examination and routine abdominal computed tomography preoperatively was 96.3% and 42.5%, respectively. Also, 8% of men developed a new hernia.


CONCLUSIONS
Although abdominal computed tomography can identify inguinal hernias in men undergoing open RRP, the test's sensitivity is inferior to that of a simple physical examination. All candidates for open RRP should undergo a careful physical examination to identify asymptomatic inguinal hernias. Our findings suggest that the previously reported high incidence of symptomatic inguinal hernias that developed after open RRP can be explained by a failure to diagnose preexisting inguinal hernias and the development of new hernias.
