Pelvic lymphadenectomy in radical perineal prostatectomy via perineal inscision our initial experience; case series

Introduction & Ojectives –A major limitation of Radical perinealprostatectomy(RPP) was second access for pelvic lymph node dissection. We aimed to assess feseability of pelvic lymphadenectomy through same perinealinsciscion. Methods –A total series of eighteen RPP cases were categorized by partin risk estimation. Eleven cases were risk (greater than 5 %). Pelvic lymphadenectomy attemted in eleven cases, lymphadenectomy operative time, number lymphnode removed, conversion and completion noted. Results: Lymphadenectomy attempted through same perinealinscision in all the elevenpatients, completed in five patients (45.45 %) and not feasiblein six patients (54. 54%). The averagelymph nodes removed were 4.7 (3- 15) in right and 3.8 (0-6) in left.Lymphadenectomy Operative time(Mean) 74.55 ( 60 - 90) minutes. The average distance between common iliac artery -bifurcation and pubic symphysis(midpoint) calculated preoperatively from imaging (CT/MRI)was 12.44 cm (11.5-14).The completion of lympadenectomy in distance < 12.5 cm was 80 % and conversion rate indistance > 12.5 cm was 66.66%.
