Application of percutaneous nephrolithotomy combined with da Vinci Xi robot in complicated upper urinary tract repair surgery: A case report

Duplex kidney and ureter is a congenital malformation. Few patients present with hydronephrosis caused by obstruction of the ureteropelvic junction of the duplex kidney, but lower kidney calculi caused by a duplex kidney abnormality is rare. This study reports a case of a duplex kidney and ureter complicated by multiple calculi in the duplex lower kidney. Percutaneous nephrolithotomy combined with a da Vinci robot-assisted laparoscopic upper urinary tract reconstruction was performed. The lower ureter was resected, and the lower kidney was preserved. One year after the surgery, a follow-up examination reported satisfactory renal function without hydronephrosis or calculi.

Automated summary

This study presents a case of recurrent calculi complicated by duplex kidney and ureter, treated with percutaneous nephrolithotomy and da Vinci robot-assisted laparoscopic upper urinary tract reconstruction. One year post-surgery, satisfactory renal function without hydronephrosis or calculi was reported.
