Abstract:
ObjectiveTo assess the safety and efficacy of retrograde ureteroscopy lithotomy (URSL)assisted antegrade percutaneous nephrolithotomy (PCNL) for complex upper ureteral calculi in semisupine-lithotomy position.MethodsFrom March 2007 to December 2010,a total of 95 patients with complex upper ureteral calculi underwent retrograde URSL assisted antegrade PCNL in semisupine-lithotomy position.Ureteral calculi size was 12 mm × 6 mm to 38 mm × 15 mm,24 cases combined with renal calculus.Firstly retrograde URSL was performed,once the stone fragments moved up to renal pelvis,a 16-22 F PCNL working channel was established under the ultrasound guidance through which lithotripsy was performed using an ureteroscope.Finally a 6-7 F double-J tube was indwelled.ResultsOperations were successfullycompleted in 93 patients.However,in it 2 patients were converted to open surgery because of significantureteral distortion due to previous open surgery.Operative time was(42.7 ± 14.9) min; estimated blood loss was(34.5 ± 26.1 ) ml.The ureteral calculi clearance rate was 100.0％,and renal calculus clearance rate inthose combined with renal calculus was 95.8％ (23/24).There were no major intraoperative and postoperative complications excepted early urinary leakage in 2 cases and fever ≥39℃ in 3 cases.ConclusionsRetrograde URSL assisted antegrade PCNL in semisupine-lithotomy position is safe and feasible for complex upperureteral calculi,especially non-opaque calculi,combined with renal calculus,easily ascending ureteral calculi and large calculi burden which has low calculi clearance rate after URSL.The outcomes are encouraging with fewer complications.It also avoids intraoperative change of patient's position.
