Class I	Extrafascial hysterectomy Deflection and retraction of the ureters without dissection of the ureteral bed Uterine artery, uterosacral ligament and cardinal ligament are not removed No vaginal cuff removed	Type I	Simple hysterectomy	Type A	Extrafascial hysterectomy Visualisation or palpation, or both, of the ureters without dissection of the ureteral bed Uterine artery, uterosacral ligament and cardinal ligament are not transected at a distance from the uterus Minimal vaginal cuff removed (< 10 mm)
Class II	Modified radical hysterectomy (Wertheim) Ureters are freed from the paracervical position but are not dissected out of the pubovesical ligament Uterine arteries divided just medial to the ureter Uterosacral ligaments resected midway between the uterus and their sacral attachments Medial half of the cardinal ligaments removed Upper one‐third of the vagina removed Elective pelvic lymphadenectomy	Type II	Modified radical hysterectomy The uterus, paracervix and upper vagina (10‐20 mm) are removed after dissection of the ureters to the point of their entry to the bladder Uterine arteries are cut off and ligated Medial half of parametria and proximal uterosacral ligaments are transected	Type B	Ureters are unroofed and rolled laterally Partial removal of uterosacral and vesicouterine ligaments Transection of the paracervix at the level of the ureteral tunnel At least 10 mm of the vagina from the cervix or tumour is resected
					B1	Without removal of lateral paracervical lymph nodes
					B2	With additional removal of lateral paracervical lymph nodes
Class III	Classic radical hysterectomy (Meigs) Complete dissection of the ureter from the pubovesical ligament to entry in the bladder except a small lateral part so that the superior vesicle artery is conserved Uterine vessels divided at origin from the internal iliac artery Uterosacral ligaments resected at their sacral attachments Cardinal ligaments resected at the pelvic wall Upper half of the vagina removed Routine pelvic lymphadenectomy	Type III	Radical hysterectomy En bloc removal of the uterus with the upper third of the vagina along with the paracervical and paravaginal tissues Uterine arteries are cut off and ligated at their origin The entire width of the parametria is resected bilaterally The entire uterosacral ligament is resected	Type C	Ureters are completely mobilised Transection of the uterosacral ligament at the rectum Transection of the vesicouterine ligament at the bladder Complete transection of the paracervix 15–20 mm of the vagina from the cervix or tumour and the corresponding paracolpos is resected routinely
					C1	With preservation of autonomic nerves
					C2	Without preservation of autonomic nerves
Class IV	More radical than class III in three aspects: (i) Complete dissection of the ureter from the pubovesical ligament (ii) The superior vesicle artery is sacrificed (iii) Upper three‐quarters of the vagina removed	Type IV	Extended radical hysterectomy Differs from class III in that three‐fourths of the vagina and paravaginal tissues are resected	Type D	D1	Resection of the entire paracervix at the pelvic side wall together with the hypogastric vessels, exposing the roots of the sciatic nerve
					D2	Type D1 plus resection of the entire paracervix with the hypogastric vessels and adjacent fascial or muscular structures
Class V	More radical than class IV Excision of involved portion of distal ureter or bladder and reimplantation of ureter into the bladder	Type V	Partial exenteration Terminal ureters or segments of bladder or rectum are resected along with the uterus and parametria
For all types, lymphadenectomy is described separately according to four levels (external and internal iliac, common iliac, aortic inframesenteric and aortic infrarenal) and radicality (sentinel node sampling, random sampling, removal of enlarged nodes only, systematic lymph node dissection or debulking)
