Abstract:
Objective To introduce the surgery procedure of pin-shaped bipolar plasmakinetic transurethral en bloc resection of non muscle-invasive bladder urothelial carcinoma and investigate the clinical outcomes.Methods 42 cases of non muscle-invasive bladder urothelial carcinoma who received bipolar plasmakinetic transurethral en bloc resection from May 2015 to March 2016 were recruited in the present study.Male 29 cases, female 13 cases, average age 52-82 years old, average (65.6 ±12.3) years old.Wide basal tumors were noticed by preoperative cystoscopy, bladder tumors were confirmed by tumor biopsy.Full-thickness specimens were obtained in procedures, including tumor, mucosa, lamina propria layer, muscular layer, to accurately assess tumor infiltration depth and staging.Results All 42 cases were done by this procedure successfully.A total of 65 pieces of tumors were excised:36 in lateral wall, 19 in posterior wall, 10 in bladder triangle.Tumor diameter ranged from 0.5 to 3.5 cm, with an average (2.1 ± 0.6) cm.Postoperative pathological stages were clear:16 cases were Ta stage and 49 cases were T1 stage ( of which 32 were T1 G3 ) .Intraoperative obturator nerve reflex happened in 2 cases.Followed up for 2-11 months, average 6 months.Tumor recurrence in 3 cases, no progression case.Conclusions Pin-shaped bipolar plasmakinetic electrode transurethral en bloc resection of non muscle-invasive bladder urothelial carcinoma is safe and reliable and should be recommended in management of non muscle-invasive bladder urothelial carcinoma.Full-thickness postoperative specimens can provide accurately judgement of the depth of tumor invasion and pathological staging.
