Objective: To compare the clinical efficacy of retrograde and traditional minimally invasive percutaneous nephrolithotomy. Methods: Records of 42 cases of kidney stones were retrospectively reviewed. Among all the patients, 20 cases received traditional minimally invasive percutaneous nephrolithotomy (MPCNL), and the other 22 cases were treated with retrograde minimally invasive percutaneous nephrolithotomy (RMPCNL). The operation time, intraoperative blood loss, postoperative hospital stay, incidence of complications, and stone removal rate were compared between the two groups 3 months after surgery. Results: The operation time of RMPCNL was significantly longer than that of the MPCNL (P<0.05). And the intraoperative blood loss in the patients treated with RMPCNL was significantly less than that in the patients treated by MPCNL (P<0.05). Moreover, the incidence of complications in the RMPCNL group was lower than that in the MPCNL group. However, there were no significant differences between the two groups in postoperative hospital stay and stone removal rate (P>0.05). Conclusion: RMPCNL can significantly reduce the probability of intraoperative bleeding and the incidence of complications. |
