Semen analysis and physical examination are performed while first evaluation for patients with male infertility. Alcohol, smoking and dietary habits can affect the semen parameters. This study aimed to evaluate whether semen parameters are changed with sexual arousal. After excluding, 100 patients with ages of 18–45 were included to the study. All semen analysis were performed with three days of sexual abstinence. An identified 20 min video link was determined to the patients and while the sexual abstinence were told to watch this video once a day; after 3 days abstinence semen analysis was examined again. In the detailed examination normal spermatozoa ratio (Tygerberg strict criteria), spermatozoa concentration, semen volume, total motility and progressive motility ratios were noted. When the two semen analysis from the same patient are compared, it was observed that all parameters did not change except semen volume and total motile sperm count (p < 0.001). In conclusion, to understand the effect of sexual arousal during the sexual abstinence, we need studies with high patient number and longer follow‐up. [ABSTRACT FROM AUTHOR]

Background: The prevalence of urolithiasis is nearly 20% and patients with urolithiasis constitute an essential part of the patients referred to the urology clinic. Many parameters should be considered for the management of renal stones and authors recommend extracorporeal shockwave lithotripsy (SWL), retrograde intrarenal surgery (RIRS), and percutaneous nephrolithotripsy (PNL), as treatment options. Among these techniques, SWL does not require general anesthesia, has 89% success rate for renal pelvic stones: 83% for upper caliceal stones, 84% for middle caliceal stones, and 68% for lower caliceal stones. In this study, we aimed to investigate whether the previously failed SWL treatment affects RIRS outcome. Methods: Patients who underwent RIRS for kidney stones between January 2012 and December 2017 in Diskapi Yildirim Beyazit Training and Research Hospital were reviewed retrospectively. Patients treated with primary RIRS (186 patients) were classified as Group 1. The outcomes of these patients were compared with those of 186 patients who underwent RIRS after failed SWL treatment using matched-pair analysis, and these patients were classified as Group 2. Results: The procedure success was defined as the sum of the stone-free and clinically insignificant residual fragments (CIRFs); final success rates were 90.3% and 91.9%, respectively. If we compare the final success rates, there was no statistically significant difference between both groups (P = .584). Conclusions: As a result, there is no negative effect of the previous unsuccessful SWL treatment on the RIRS success. Patients with CIRF should be followed up more carefully in terms of becoming symptomatic. [ABSTRACT FROM AUTHOR]

INTRODUCTION: We aimed to determine whether there was a relationship between the perception of renal colic pain and different psychosocial and physiological factors. METHODS: Between May 2021 and July 2022, we prospectively analyzed 320 patients over the age of 18 who were diagnosed with renal colic occurring unilaterally and secondary to a single kidney stone of any size. Body mass index (BMI), education level, hospital anxiety and depression scale (HADS), somatosensory amplification scale (SAS), and the visual analog scale (VAS) features of stone (diameter, Hounsfield value, and localization) and degree of hydronephrosis were analyzed. Correlation analysis of VAS score and these parameters were completed with Spearman’s test. The regression analysis was used to determine the predictive factors of severe pain. RESULTS: There was no significant difference found between sex and VAS scores of colic pain (p=0.122). We found a significant correlation between VAS score and localization of kidney stone, degree of hydronephrosis, and anxiety level of patients. High grade of hydronephrosis and high anxiety level were found to be associated with high VAS scores (p<0.001 and p=0.035, respectively). It was shown that SAS and level of depression did not correlate with pain. Only a high degree of hydronephrosis was found to be a predictive factor for severe pain (p<0.01). CONCLUSIONS: The patient’s high anxiety level and a high degree of hydronephrosis were positively correlated with renal colic pain caused by kidney stones. With this study, the severity of pain in patients with a high degree of hydronephrosis and high anxiety can be predicted and may be a criteria to select suitable treatment to reach faster response.

This paper presents the use of Industrial Big Data at Tupras Refinery to increase productivity and energy efficiency by preventing unplanned down time and faulty operation of the equipment. Data obtained from existing protection devices are used through analytics included in software called iMCM. It provides the user with condensed information needed about pending faults of equipment, time to failure and suggested actions anytime and anywhere it is needed. Both its installation and its use are simple without requiring hardware installation, new hardware, sensors, cabling, equipment shutdown and visits to the site. Its simplicity and its ease of use makes it possible for many companies that have been aware of the benefits of predictive maintenance, but had found it too complicated. Analytics, which was previously developed for the Space Shuttle Main Engine, gas turbines and helicopter engines, for early warning of pending faults of industrial equipment is used.

Purpose: In our study, we assessed the efficiency and reliability of retrograde intrarenal surgery secondary to open surgery for kidney stone treatment. Moreover, we compared the efficiency and safety of retrograde intrarenal surgery for the patients with previous history of open surgery, percutaneous nephrolithotomy, secondary retrograde intrarenal surgery (RIRS) and primary RIRS.Materials and Methods: Data was retrospectively reviewed. Patients who had kidney anomalies, who had been stented due to ureteral stricture in the operation and who were < 18 years old, were excluded. There were 30 patients who underwent RIRS secondary to open surgery. The demographic and stone characteristic as well as intraoperative and postoperative data of the patients were recorded. 30 patients with similar demographic and stone characteristics to those patients were selected by match pairing method from patients who had previous PNL, RIRS history and had undergone primary RIRS. A total of 120 patients, in total 4 groups, were included in the study.Results: Statistically significant difference was detected among the groups with regards to shock wave lithotripsy history and preoperative JJ stent rate. There was no statistically significant difference in terms of stone characteristics, intraoperative and postoperative data.Conclusion: RIRS is an efficient and safe method for kidney stone treatment of the patients with previous history of open surgery, percutaneous nephrolithotomy and retrograde intrarenal surgery. It has a similar efficiency and safety for the patients who have undergone retrograde intrarenal surgery. This is the first study that compares the patients especially  with different previous surgery methods. [ABSTRACT FROM AUTHOR]
