      The number of pelvic lymph nodes Lymph node count is the most commonly used method to evaluate the extent of PLND. Canessa et al. cleared pelvic lymph nodes below the bifurcation of iliac vessels in 16 cadavers and obtained a mean of 28.6 (16–46) nodes [12]. In our e-PLND, the mean number of nodes

Agreement for lymph nodes with largest diameter of 5 mm or greater between radi-ologists ranged from 70.5% to 97.6% for the five anatomic locations with poor interobserver agreement (κ, 0.2–0.3).

The five year survival of patients with lateral pelvic lymph node metastasis has been found to be comparable to patients with resectable liver or lung metastasis, as about 40% and recurrence free survival is about 55% [13,14]. These data are based on the reports from Japan and China.

The extent of PLND and the number of retrieved nodes are summarized in Table 2 [3-5,7,10,12,17,22-26,28-30,34-43]. In two large cystectomy series that involved extended PLND, the me-dian number of lymph nodes removed was 30 to 43 [4,37].

      The standard protocol for examining pelvic lymph nodes was to process the entire specimen in blocks of 3 mm thickness and to examine one haematoxylin and eosin (H&E) stained section from each block.This approach is based on the typical form of the pelvic lymph nodes. They are usually palpable but hardly visible, being extensively replaced by adi-

      Pelvic Lymph Nodes Many authors [17–19] have proposed the anatomic locations and the nomenclatures of pelvic LN groups. We use the nomenclature proposed by McMahon et al.
