  • Objective To compare therapeutic effects of percutaneous nephrolithotomy (PCNL), minimally invasive percutaneous nephrolithotomy (MPCNL) and flexible ureteroscopy (FURL) for subrenal calyx calculi under 20 mm. Methods 150 patients with subrenal calyx calculi <20 mm were randomly assigned to three groups ( n=50). Patients in different groups received PCNL, MPCNL and FURL respectively, and the operation time, bleeding volume, length of stay, postoperative out-of-bed activity time, visual analogue scale (VAS) scores at the first postoperative day, stone free rates and incidence rate of postoperative complications in each group were recorded and compared. Results Operation time in the PCNL group was the shortest among three groups, and its bleeding volume and ambulation time were significantly lower compared to those in PCNL group (P<0.05). Bleeding volume, length of stay, post-operative out-of-bed activity time and VAS scores on the first postoperative day in FURL group were significantly lower than those in PCNL group and MPCNL group (P<0.05). Instant and final stone free rates were high in PCNL, MPCNL and FURL group, and there were no significant differences among them (P>0.05). The incidence rate of postoperative complication was lower in FURL group than that in PCNL and MPCNL group (P<0.05). Conclusion PCNL, MPCNL and FURL are effective treatments for subrenal calyx calculi under 20 mm. FURL, with shorter recovery time and lower incidence rate of postopertive complications, is less invasive compared to PCNL and MPCNL, thus worthy of clinical application and promotion.
