Endoscopic versus laparoscopic management of noninvasive upper tract urothelial carcinoma: 20-year single center experience

Purpose: We compare the outcomes of endoscopic surgery to laparoscopic nephroureterectomy for the management of specifically noninvasive upper tract urothelial carcinoma. Materials and Methods: A retrospective database review identified consecutive patients with clinically noninvasive upper tract urothelial carcinoma who underwent endoscopic surgery (59, via ureteroscopic ablation or percutaneous resection) or laparoscopic nephroureterectomy (70) at a single center during 20 years (1991 to 2011). Overall survival, upper tract urothelial carcinoma specific survival, upper tract recurrence-free survival, intravesical recurrence-free survival, progression-free survival and renal unit survival were estimated using Kaplan-Meier methods, with differences assessed using the log rank test. Results: Median age and followup were 74.8 years and 50 months, respectively. Overall renal preservation in the endoscopic group was high (5-year renal unit survival 82.5%), although this came at a cost of high local recurrence (endoscopic surgery 5-year recurrence-free survival 49.3%, laparoscopic nephroureterectomy 100%,
