Urothelial carcinoma of upper urinary tract (UTUC) is a rare disease. Nephroureterectomy and excision of bladder cuff is the standard of surgical treatment. The approaches for this surgery have evolved enormously in the past few decades. Laparoendoscopic single site (LESS) surgery is one of the surgical options with the advantages of fast recovery and good cosmesis. We reported our preliminary results of a completely extraperitoneal LESS approach via a Gibson’s incision, which is a novel way of access in performing this operation.
Materials and Methods:
From September 2013 to September 2014, 10 patients accepted LESS retroperitoneal nephroureterectomy with excision of bladder cuff through a 5 Gibson’s incision by a single surgeon. GelPOINT (Applied medical) was adopted as the access platform. The mean age of the patients was 76.3 years (range 56-87). There were 4 male and 6 female.
All the procedures were smoothly carried out without sequela. The mean total operation duration was 330 minutes (range 230-430). The mean duration for nephrectomy was 163.8 (range 120-230). The mean blood loss of nephrectomy was 145 mL (range 50-300). There was no conversion to open or conventional laparoscopic approach. Transperitoneal LESS approach was performed in one patient due to obvious violation of the peritoneum. There were no post-operative events. The cosmesis was satisfactory.
The preliminary results of our novel LESS retroperitoneal approach for nephroureterectomy with excision of bladder cuff were promising. Such approach may be one of the choices for the surgical treatment of UTUC.
