摘要
Introduction: We reported the pneumovesicum (PV) approach to lower ureter and bladder cuff excision and closure. We believe that this approach bears the closest resemblance to the laparoscopic skill set of intravesical dissection and suturing. Herein, we report the midterm oncological results of the approach's use in a series of patients with upper tract urothelial cancer. Materials and Methods: From July 2004 to May 2010, 10 patients with upper tract urothelial cancer who underwent PV-assisted laparoscopic nephroureterectomy (LNU) were reviewed. Laparoscopic ports were inserted into the bladder via a suprapubic route, and carbon dioxide PV was induced. Laparoscopic dissection of the lower ureter and excision of the bladder cuff were then performed. The bladder defect was securely closed using laparoscopic suturing, and standard LNU followed. Results: Nine men and one woman with a mean age of 71.6 years (47–82) underwent the procedure. Six of the patients had renal pelvic tumor, two had upper ureter tumor, one had midureter tumor, and one had synchronous renal pelvis and upper ureter tumor. In terms of final pathology, there were three, two, and five patients with T1, T2, and T3 diseases, respectively. All of the patients had grade 2 (G2) disease, except for two with grade 3 (G3) disease. Over a median follow-up of 46 months (22–67 months), four patients developed superficial bladder tumor recurrence. The bladder and systemic recurrence rates were 40% and 10%, respectively. There was no port site recurrence. Conclusion: Based on our midterm follow-up information, it can be concluded that the PV approach to en-bloc bladder cuff excision and LNU for upper tract urothelial cancer provides intermediate oncological results comparable to those of other approaches to en-bloc excision of the bladder cuff.
