Introduction

There is no research report to compare clinical outcomes of flexible ureteroscopic lithotripsy (URS) at different body positions. We sought to compare the safety and efficacy of oblique supine lithotomy position and supine lithotomy position in suctioning flexible URS.

Methods

A total of 82 patients with upper urinary calculi were divided into two groups. Group 1 included 47 patients who were treated by suctioning flexible URS in oblique supine lithotomy position. Group 2 included 35 patients who were treated in supine lithotomy position. There were no significant statistical differences in the age, gender and rate of comorbidities between the two groups before surgery (p>0.05). The operative time, stone-free rates at postoperative day 30, renal pelvic pressure (RPP) ?postoperative complications (graded by the Clavien system) and length of stay were compared.

Results

Retrograde intrarenal surgery was successful in 73 patients in the first surgery; it was also completed successfully in other 9 patients after indwelling a double-J stent for 2 weeks. Compared with supine lithotomy position, a significantly greater stone-free rate on postoperative day 30 and a significantly shorter operative time were noted (p<0.05 each). There were no differences in complication rates of Clavien grade I and Clavien grade II, RPP and length of hospital stay (p> 0.05).

Conclusions

Suctioning flexible URS in the oblique supine lithotomy position is safe and more effective than the supine lithotomy position.
