Objective: We introduce the innovative Institute of Urology,Peking University(IUPU)techniques for retroperitoneal laparoscopic surgery for the upper urinary tract,which have been published by Department of Urology,Peking University First Hospital and Institute of Urology,Peking University,and promote their widespread use in the field of urology.Methods: We summarized the innovative retroperitoneal laparoscopic techniques published in medical journals by our department.Results: There are more than 10 innovative techniques in retroperitoneal laparoscopic surgery which have been published in influential journals by IUPU.These include:(Ⅰ)the modified patient positioning for retroperitoneal laparoscopic surgery;(Ⅱ)the IUPU technique to set up the retroperitoneal space;(Ⅲ)the anatomical retroperitoneoscopic nephrectomy;(Ⅳ)the laparoscopic aspiration technique for central or giant renal angiomyolipoma;(Ⅴ)the combined retroperitoneal and transperitoneal pathway for pure laparoscopic radical nephrectomy and inferior vena cava(ⅣC)tumor thrombectomy;(Ⅵ)for megaureter,the laparoscopic ureteral reimplantation technique with extracorporeal tailoring and direct nipple ureterocystostomy;(Ⅶ)the modified standardized suturing for UPJO;(Ⅷ)the complete retroperitoneal laparoscopic nephroureterectomy for upper urinary tract urothelial carcinoma(UTUC).Conclusions: These IUPU innovative or modified techniques have improved the treatment efficacy for related diseases and contributed to the progress of our department.
