ABSTRACT
Objective To investigate the intracavitary surgical therapy and efficacy for the patients with duplex kidney and ureter with upper urinary tract calculi. Methods The clinical data of twenty-six cases with duplex kidney and ureter with upper urinary tract calculi were retrospectively analyzed. Results Of 26 patients who underwent intracavitary surgical treatment, 5 patients were treated by ureteroscopic lithotripsy (URL), 15 by retrograde intrarenal surgery (RIRS), 6 by mini-percutaneous nephrolithotomy (mPCNL). All 26 cases were performed successfully. No severe complications such as septic shock, heavy blood loss, ureter injury, and pneumothorax occurred. 23 patients with nephrohydrosis were followed up for 2 to 24 months and most of them improved at different extents. Conclusion The current technique of intracavitary surgery in the management of duplex kidney and ureter concomitant with upper urinary tract calculi, has the advantages of less trauma, rapid recovery, safety and so on.
