ABSTRACT
ABSTRACT Purpose It has been reported that calcitonin receptor (CALCR) gene polymorphisms might be associated with calcium stone urolithiasis. Owing to mixed and inconclusive results, we conducted a meta-analysis to summarize and clarify this association. Materials and Methods A systematic search of studies on the association between CALCR gene polymorphisms and calcium stone urolithiasis susceptibility was conducted in databases. Results Odds ratios and 95% confidence intervals were used to pool the effect size. Five articles were included in our meta-analysis. Conclusions CALCR rs1801197 might be associated with increased risk of calcium stone urolithiasis. There is insufficient data to fully confirm the association between CALCR rs1042138 and calcium stone urolithiasis susceptibility. Well-designed studies with larger sample size and more subgroups are required to validate the risk identified in the current meta-analysis.

Objective To evaluate the efficacy of flexible ureteroscopy combined with holmium laser lithotripsy for the treatment of subrenal calyx calculus, and comparing with digital flexible ureteroscope and modular flexible ureteroscope with holmium lithotripsy for the difference of the efficacy of the treatment of subrenal calyx calculus. Methods Review of the clinical data of 93 patients with subrenal calyx calculus, of which 48 cases were treated with digital flexible ureteroscope (digital flexible ureteroscope group, DFU group), 45 cases with modular flexible ureteroscope treatment (modular flexible ureteroscope group, MFU group), lithotripsy effect and complications were compared between the two groups. Results The mean operation time, one-session stone-free rate were significantly different between the two groups (P < 0.05). No significant differences in hospital stay, the success rate of looking for calculus, complication and hospitalization expense (P > 0.05). Conclusion With digital flexible ureteroscope and modular flexible ureteroscope treatment of subrenal calyx calculus all are safe and effective. The use of DFU than the use of MFU in the treatment of subrenal calyx calculus operation time is shorter, stone-free rateis higher, the effect is better. There is little difference between their hospitalization expenses, but the use of MFU can reduce the cost of the department.
