PURPOSE: To evaluate the efficacy of oral dissolution therapy (ODT), shock wave lithotripsy (SWL), and combined SWL and ODT for medium-sized radiolucent renal stone (RLS). METHODS: A randomized controlled trial for patients with medium-sized RLS, 1-2.5 cm, ≤ 500 Hounsfield unit (HU). The ODT patients were counseled for oral potassiumsodium-hydrogen citrate (Uralyt-U®). The 2nd group underwent SWL and the last group had combined SWL and ODT. The primary outcome, stone-free rate (SFR) at 3 months, was assessed by non-contrast computed tomography (NCCT). We defined complete response (success) if no residual fragment were detected by NCCT; partial response (failure) if there was a decrease in stone size, but presence of residual stones; no response if there was no change or increase in stone size (failure). RESULTS: 150 patients completed follow-up. The SFR at 1st month and 3rd month were, respectively; 16% and 50% in the ODT group, 10% and 46% in the SWL group, and 35% and 72% patients in combined group with (p = 0.03 and 0.003, respectively. The overall SFR for all groups was 66%. Combined treatment and initial response in first month follow-up were independent factors predicting SFR. In addition, combined treatment significantly decreased the overall stone volume (p = 0.03) and the need for additional stone management procedures after 3 months (p = 0.01). CONCLUSION: Combined ODT and SWL treatment constitutes the most rapid and effective therapeutic approach for medium-sized RLS, decreasing overall stone volume as well as the number of SWL sessions needed in comparison to SWL therapy, alone.

Chronic hepatitis C is implicated in insulin resistance (IR) susceptibility. An X-ray repair cross-complementing group 1 gene (XRCC1) is proposed to be a candidate gene for a study of IR susceptibility. So, this study aims to investigate the possible association of the XRCC1 gene polymorphisms with the risk of IR related to chronic hepatitis C virus (HCV) infection in Egyptian patients. In a case-control study, a total of 210 subjects, including 140 chronic HCV patients (87 patients with IR and 53 without IR) and 70 healthy controls, were included. Two genetic polymorphisms (c.1254C > T and c.1517G > C) of the XRCC1 gene were genotyped via the PCR-restriction fragment length polymorphism (PCR-RFLP) technique. The result of the current study revealed that these two single nucleotide polymorphisms (SNPs) have statistically significant influences on susceptibility to IR in chronic HCV infected Egyptian patients. It could be concluded that c.1254C > T, the TT genotype, CT/CC carriers as well as c.1517G > C, the CC genotype and GC/GG carriers might be associated with increased IR susceptibility. Moreover, T-allele of c.1254C > T and the C-allele of c.1517G > C genetic variants might influence the susceptibility.
