A Comparative Study of Mini-invasive Percutaneous Nephrolithotomy and Ureteroscopic Lithotripsy Combined with Occlusion Devices for the Treatment of Upper Incarcerated Ureteral Stones / 中国微创外科杂志

ABSTRACT

Objective To compare the efficacy of ureteroscopic lithotripsy ( URL) combined with occlusion devices and mini-invasive percutaneous nephrolithotomy ( MPCNL) in the treatment of upper incarcerated ureteral stones. Methods A total of 89 patients with unilateral upper ureteral calculi were enrolled from April 2011 to July 2013, 42 of which were treated with MPCNL and 47 of which were treated by rigid ureteroscopic lithotripsy combined with occlusion devices. Resuts There were no significant differences in the success rate of primary lithotripsy (97.6% vs.95.7%, χ2 =0.000, P=1.000).No marked differences were detected in the stone clearance rate (97.5% vs.95.6%, χ2 =0.000, P=1.000), complication rate (7.1% vs.8.5%, χ2 =0.000, P=1.000) and operation time [(80.2 ±11.9) min vs.(65.1 ±10.9) min, t =6.248, P=0.000] between the two groups.The hospitalization time in the URL group was (3.5 ±1.5) d, which was obviously shorter than that in the MPCNL group , in which it was (7.3 ±1.5) d(t=11.931, P=0.000). Conclusion URL combined with occlusion devices can obtain satisfactory results as well as MPCNL in the treatment of upper ureteral calculi by proper case selection and careful operation performance .
