초록

Purpose: The aim of this study was to determine the risk factors for developing an inguinal hernia after undergoing radical retropubic prostatectomy(RRP).
Materials and Methods: We retrospectively investigated the hospital records of 382 patients who underwent RRP and who were followed over 12 month periods at our institute between January 2000 and December 2006. All the operations were performed by a single surgeon. The clinical and pathological parameters were compared between the patients with and without inguinal hernia, and the risk factors were analyzed using the Cox proportional hazards model.
Results: The mean age of the patients was 64.6 years(range, 40 to 83). 32(8.3%) of the 382 patients developed an inguinal hernia at a mean time of 14 months. 8(25.8%) of 32 patients developed an inguinal hernia within 6 months, 23(61.8%) within 1 year, 26(83.9%) within 2 years and 28 (90.3%) developed an inguinal hernia within 3 years. 25(78.1%) developed an inguinal hernia in the right side, 3(9.4%) in left and 4(12.5%) developed an inguinal hernia in both sides. The operative time(p＜0.001), prostate volume(p=0.001), the presence of transfusion (p=0.001) and pelvic lymph node dissection(p=0.007) were significantly different between the patients with and without inguinal hernia. Multivariate analysis showed that the operative time(p=0.039), pelvic lymph node dissection(p=0.002), the presence of transfusion(p=0.012) and the prostate volume(＞50cc, p=0.012) were independent predictors for post-prostatectomy inguinal hernia.
Conclusions: The results of our study show that the duration of surgery, pelvic lymph node dissection, the presence of transfusion and the prostate volume all increase the risk of post-radical retropubic prostatectomy inguinal hernia.
