PCNL and RIRS are safe and effective methods for medium-sized LP calculi. For selected patients, RIRS may represent an alternative therapy to PCNL, with acceptable efficacy and low morbidity.

Previous studies have investigated whether physical activity increases serotonin hormone levels. Serotonin receptor dysfunction is one of the frequently accused factors of premature ejaculation (PE). Nevertheless, no studies up to date have demonstrated that the association between physical activity and premature ejaculation. We aimed to investigate the relationship between physical activity and PE and determine whether moderate physical activity might delay ejaculation time or be an alternative treatment for PE. A total of 105 patients diagnosed with PE were enrolled in this study. Of the patients, 35 were treated with dapoxetine, (30 mg) on demand (Group 1), 35 performed moderate physical activities (Group 2), and 35 performed minimal physical activity (Group 3-sham). Demographic characteristics, metabolic equivalents (MET), premature ejaculation diagnostic tool (PEDT) and intravaginal ejaculatory latency time (IELT) were recorded. There were no significant differences among three groups in terms of age, BMI, MET, PEDT or IELT before treatment. At the end of the study, there was significant decrease in PEDT scores, and increase in IELT in groups 1 and 2 as compared to Group 3. In conclusion, a moderate physical activity longer than 30 min at least 5 times a week leads to ejaculation delay, and appears as an alternative to dapoxetine on demand for the treatment of PE.

To compare the success and complications of ultra-mini percutaneous nephrolithotomy (UPNL) and standard percutaneous nephrolithotomy (SPNL) techniques. We prospectively analyzed 50 patients who underwent SPNL, and 47 patients who underwent UPNL. The patients with a stone size equal to or smaller than 25 mm and we used flipping a coin as the randomization technique. The mean stone size was 20.9 ± 3.6 mm in SPNL, and 20.3 ± 3.0 mm in ultra-mini PNL groups. Stone free rates were 88 % (44/50 patients) and 89.3 % (42/47 patients) in SPNL and UPNL groups, respectively, without any significant difference in between (p = 0.33). No major complications were seen in the UPNL group. PNL has been modified into micro PNL and UPNL parallel to the technological advances to decrease the complications of PNL. When performed as we do UPNL may be an alternative method to SPNL without any additional smaller-calibred nephroscope and with a similar high success rate.
