Abstract:
Objective:To discuss the surgical techniques and clinical value of pure laparoscopic radical nephroureterectomy without changing patient’s position in the treatment of upper tract urothelial carcinoma(UTUC).Methods:The clinical data of 28 patients, who underwent pure laparoscopic radical nephroureterectomy with single patient’s position in the treatment of UTUC , were collected and analyzed, including 16 males and 12 females, with the median age of (68.3±9.7)(45-80)years.There were 20 renal pelvic carcinoma and 8 ureteral carcinoma with preoperative clinical TNM stage of T l-T 3N 0M 0. Among them, 9 tumors were located in right side, while 19 in left side. With the patient in a contralateral oblique position at 50°-70°. , an additional instrument hole is added at the midpoint between the umbilicus and pubic symphysis, besides the classical four holes. Nephrectomy was carried out routinely after the pneumoperitoneum was built, and then the ureter was dissected all the way down to bladder wall. The bladder was closed with 3-0 absorbable barbed suture following the bladder cuff being incised.The specimen were retrieved through the extended incision of the lower abdomen trocar or through vagina if suitable. There was no need to change patient’s positioning during operation. Results:All surgical procedures were successfully performed without conversion to open surgery. There was no serious bleeding or other operation related complications. The mean operative time was (136.3±48.7)(70-270)min, while the estimated blood loss was (46.3±38.3)(10-200)ml. The mean postoperative drainage volume (287.3±196.6)(30-910)ml, while the mean postoperative drainage time was 3.2(1-5)d. Their intestinal function recovered 1.5(1-4) d postoperatively. Their average postoperative hospital stay was(6.1±1.7)(3-12)d.Pathological results showed urothelial carcinoma in all cases, including 21 high grade and 7 low grade. Lymphovascular invasion was found in 7 cases of high-grade urothelial carcinoma. All the surgical margins were negative. The median follow-up was(9.2±4.8)(1-12)months, and there was neither tumor recurrence nor distant metastasis.Conclusions:Compared with the traditional operation method, single posture pure transperitoneal laparoscopic radical nephroureterectomy have the advantages of standardized operation method, simple procedure, less trauma, less bleeding and quick postoperative recovery. It is a safe and effective minimally invasive technology for the treatment of UTUC.
