Abstract: Three cases of renal pelvic neoplasm associated with staghorn calculi were enrolled to the study from March 2015 to June 2019. All patients underwent minimally invasive procedures previously including extracorporeal shock wave lithotripsy (ESWL), flexible ureteroscopic lithotripsy(FURL), or percutaneous nephrolithotripsy (PCNL). 3 patients of renal pelvic neoplasm with giant staghorn calculus were diagnosed by resection biopsy during laparoscopic pyelolithotomy intraoperatively and then treated by laparoscopic radical nephroureterectomy (LRNU). Case 1 was identified retroperitoneal lymph node metastasis 16 months after operation. Case 2 and 3 remained disease free. The timely diagnosis of renal pelvic neoplasm associated with staghorn calculi is always difficult, nevertheless, the laparoscopic pyelolithotomy with resection biopsy intraoperatively can be more effective in selected cases compared with routine endoscopic biopsy.
