To investigate the applicability of the combined spinal-epidural anesthesia (CSEA) method in RIRS for the treatment of kidney stone disease and also to compare with general anesthesia (GA) in terms of their effects on early postoperative pain levels and their cost. A hundred consecutive patients who were scheduled for RIRS were enrolled in this study and were prospectively evaluated according to the anesthesia methods. Patients were divided into 2 groups randomly: the GA (N.=50) and CSEA (N.=50) groups. Five patients were excluded due to patient incompatibility or inadequate anesthesia. The pain levels of patients in the Group 2 were recorded during the operation using the Visual Analog Scale (VAS) at minutes 1, 5, 10, 15, 30 and 60. Peak pain levels within the first 24 hours following the operation were recorded for both groups. Ninety five patients in the two groups were determined to be similar in terms of demographic characteristics. The mean VAS score at the postoperative 1st day was found as 1.20±0.9 for Group 1 and 0.82±1.3 for Group 2. No statistically significant differences were identified between the VAS-nram and VAS-ram groups (P=0.450). The total cost of anesthesia medications was similar between the both groups. Combined spinal-epidural anesthesia, which produces favorable outcomes in the intraoperative and postoperative periods, will become an alternative to general anesthesia. Also, the costs associated with these two anesthesia methods were calculated, it was found that the total cost of anesthesia medications and materials per operation was similar both methods.

Objective: the aim of this study is to determine the prevalence of male factor infertility with the clinical patterns of patients in our region. Materials and methods: this is a descriptive retrospective study of 406 infertility cases presented at our urology clinic from February 2018 to February 2019. We assessed hormone and physical examination data, semen analysis results, the contribution of male and female factors to infertility, and types of infertility (i.e., primary or secondary). Results: the age of the male patients ranged from 18 to 50 years, with a mean of 30 +/- 5 years. Asthenozoospermia was the leading cause of male factor infertility in 77 patients (19%). Male factors as the sole cause of infertility were found in 185 (45.6%) couples. Female factors as the sole cause were found in 32 couples (7.9%). Primary infertility was determined in 314 (77.3%) patients, and 92 (22.7%) had secondary infertility. Conclusion: according to our results, the male infertility rate was high among couples reporting infertility. Couples should be informed about the causes of infertility, which may be due factors attributed to either sex.

Objective: To compare the success and complication rates and advantages and disadvantages of retrograde intrarenal surgery (RIRS) and percutaneous nephrolithotomy (PNL) methods for the upper calyceal renal stones between 10 and 20 mm. Materials and Methods: The files of 124 patients who had upper calyceal renal stones in diameter 10–20 mm were analyzed retrospectively. Sixty-one patients were randomized as Group 1 and 63 as Group 2. The parameters as success and complication rates, fluoroscopy and operation times, preoperative and postoperative hemogram (Hb) levels, and need of blood transfusion were saved and then groups compared. Complication rates and need of second procedure numbers between groups were evaluated according to modified Clavien classification. Results: Demographic features and success and complication rates between groups were similar. Hospitalization time was 1.0 ± 0.1 day for Group 1 and 2.3 ± 1.4 days for Group 2. When preoperative and postoperative Hb difference was evaluated, 0.1 ± 0.3 mg/dL decrease was noticed for Group 1 and 1.6 ± 0.8 mg/dL decrease for Group 2. Mean operation time for Group 1 was 53.6 ± 15.1 minutes and mean fluoroscopy time was 20.1 ± 8.9 seconds for Group 1; for Group 2, these values were 67.8 ± 16.2 minutes and 53 ± 15.0 seconds, respectively. As a result, mean operation time and fluoroscopy time, hospitalization time, and Hb decrease levels were found less and as statistically significant for Group 1. Conclusion: RIRS and PNL methods both have the same success and complication rates for upper calyceal renal stones between 10 and 20 mm. However, we think that RIRS method should be preferred for suitable patients because it is a more noninvasive method and has advantages of some operation parameters over PNL.

Introduction Kidney stones occur more frequently in patients with a horseshoe kidney (HSK) anomaly. Abnormal anatomy may make the stone removal procedures more difficult. Therefore we aimed to evaluate and compare retrograde intrarenal surgery (RIRS) and percutaneous nephrolithotomy (PCNL) for the treatment of renal stones in the HSK anomaly. Material and methods In this descriptive study, patients with HSK anomaly who underwent RIRS and PCNL procedures were retrospectively evaluated. Demographic and renal stone characteristics, success and complications associated with the surgical methods were compared across patients. Results A total of 49 patients were evaluated, 28 underwent RIRS and 21 underwent PCNL. No differences were determined between the groups concerning the demographics of patients and stone characteristics. A single session and final stone-free rate was 71.4% and 85.7% in RIRS, 81% and 90.5% in PCNL (both p = 0.05). However, RIRS had more re-treatment rate, while its mean length of hospital stay was shorter than PCNL (p = 0.035, p = 0.001). While no differences were detected between the associated complication rates, more of the complications encountered in the PCNL group were of a serious nature. Conclusions In the HSK anomaly, renal stones can be treated with RIRS and PCNL procedures with high success. With its minimal morbidity, low complication rates and the minor character of the associated complications, the RIRS procedure can sometimes be preferred to avoid complications related to PCNL in HSK anomaly with big sized kidney stones.

The population of elderly adults is increasing globally, and due to metabolic changes related to advanced age, many elderly adults experience kidney stones. Flexible ureteroscopy (f-URS) is a minimally invasive procedure to treat kidney stones, but it is not free of complications. The goals of this study were to analyze the efficacy and safety of f-URS in the management of kidney stones in patients aged ≥60 years and compare the outcomes of this surgery with the outcomes of the same surgery in a younger population. We retrospectively reviewed patient data from 1750 patients who met our inclusion criteria and received f-URS at the urology clinic of our hospital from 2012 to 2017. Patients were assigned into two groups: those aged ≥60 years (Group 1, n=291) and those aged 19-59 years (Group 2, n=1459). The perioperative results were evaluated comparatively. We performed multivariable analyses for factors predicting complications. When we compared the groups on demographic attributes, we noted statistically significant differences in gender, body mass index (BMI), and American Society of Anesthesiologists scores. Stone size and operation time were higher in the ≥60-year age group (Group 1). Other stone characteristics and operative features were similar. Stone-free rates (SFR) after the first procedure were 88.0% in Group 1 and 89.2% in Group 2. SFR and success rates at three months were similar for both groups. The complication rates were similar, and multivariable regression analysis revealed the most important factor affecting the complications was the presence of residual stones in both groups. The second most important factor affecting the complication was the operation time in Group 1 and the number of stones in Group 2. In our study, there were no significant differences in terms of results and complications among elderly and young patients after f-URS except for the duration of the operation. The prolongation of operation time results in worse outcomes in terms of perioperative complications in patients aged ≥60 years. f-URS is a relatively safe and efficient procedure, with a small risk of minor complications even in the elderly population, with increased comorbidity.

Background: Retrograde intrarenal surgery (RIRS) is a safe and minimally invasive method for the endoscopic treatment of upper urinary system stones especially sized <2 cm. Ureteral entrance is an important stage of RIRS. General anesthesia (GA) is usually used for RIRS. There is not enough data about the effect of anesthesia methods on the success of ureteral entrance and RIRS. We aimed to evaluate the effects of anesthesia methods (spinal anesthesia [SA], epidural anesthesia [EA], and GA) on the ureteral access and RIRS outcomes in primary surgery. Methods: After local ethical approval, 105 patients were prospectively randomized into three groups according to the anesthesia methods. GA, SA, and EA were defined as Group 1, 2, and 3, respectively. Results: Stone density was statistically significantly different between three groups (P = .008). Lithotripsy and operation time were significantly lower in Group 3 (P = .001). Dilatation and stone access time were significantly lower in Group 1. There was no statistically significant difference for scopy time, success, Visual Analog Scale score at 8th and 24th hours, and intraoperative and postoperative complications. Conclusions: GA may be recommended to decrease manipulations for the success of first ureteral access and time to reach the stone if there is not any contraindication.
