Abstract:

Objective: To compare the curative effects of laparoscopic pyelolithotomy combined with flexible cystoscopy (LPLFC) and percutaneous nephrolithotomy (PCNL) in treatment of complex renal calculi, and to evaluate its safety.Methods: A total of 62 patients with complex renal calculi were randomly divided into LPLFC group (n=31,treated with LPLFC) and PCNL group(n=31,treated with PCNL). The operative time, the hospitalization time,the decreased values of postoperative hemoglobin,occurrence of complications and one-stage stone clearance rates of the patients in two groups were compared.Results: All the operations were finished successfully.A total of 8 patients in LPLFC group complicated with homolateral adrenal or renal diseases received synchronic laparosopic surgery. The operative time and the decreased value of postoperative hemoglobin of the patients in LPLFC group were significantly shorter and lower than those in PCNL group(t=18.3,P<0.01;t=33.2,P<0.01). A total of 5 patients(16.1%) in PCNL group required transfusion postopratively because of blood loss. The hopitaliztion time and one-stage stone clearance rate of the patients in two groups had no significant differences (t=21.2,P=0.7;t=21.9,P=0.71).Conclusion: LPLFC is a minimally invasive operation method with less blood loss, shorter operative time and higher operative safety in treatment of complex renal calculi.
