Introduction & Objectives

RPLND has an important place in the management of low and high-stage testicular cancer. It offers 2 basic benefits: accurate staging and the possibility of a surgical cure, even with metastatic disease
Approximately 80% stage II seminoma treated with chemomotherapy will present residual masses. EAU guidelines recommend biopsy or surgical resection for PET positive masses(>3cms) when feasible. PC–RPLND template depends on disease extension. According to Heidenreich criteria, unilateral modified template during PC-RPLND is suitable if the pre-chemotherapy metastases are found in the primary landing zone of the tumor-bearing testicle and if the post-chemotherapy residual masses.

Materials & Methods

Clinical case and follow-up are presented in video. PC-CT scan shows para-aortic (+0.6cms) and inter-aorto-cava (+0.4cms) lymph nodes progression with metabolic up-take on PET scan
Patient wanted to avoid significant ejaculatory morbidity and rejected bilateral template

Location (Lower incidence of cross spread disease than right tumors)
Volume (<5cms)
Low incidence of teratoma
Good prognosis (IGCCG)
A modified “full left” template RPLND was performed using a laparoscopic transperitoneal approach.
Inter-aorto-caval lymph nodes were included (Indiana university, Beck 2007).
Preoperative low fat diet, over 1 week continued 2 weeks postoperatively, was used. Vascular surgeon was previously advice.


Surgical time:136 min

Estimated blood loss:110ml.
No intraoperative complications.
Drain shows milky appearance. Biochemical analysis revealed chylascites. Median-chain fatty-acids rich diet and subcutaneous octeotride were used. Drainage decreases on 4th post-operative day and was removed on 7th post-operative day. Hospital stay: 8 days.
Histopathology: 2/11 lymph nodes positive for pure seminoma. <10% viable tumor Post RPLND PET scan shows a right retrocrural mass. Patient received salvage chemotherapy (TIPx2).
PC-PET scan shows no evidence of the disease.
18 months follow up: patient is recurrence free, preserves antegrade ejaculation and is asymptomatic.


Resection of residual disease was technically challenging due to desmoplastic reaction. Complications were avoided with careful dissection 

Template boundary is a matter of actual debate. Experience on seminomas is limited discussed.
No infield relapse inside of modified template was detected. Follow up is a limitation.
As surgical series of limited dissections continue to mature, extent of PC-RPLND remains controversial.
