Abstract
OBJECTIVES To suggest a novel disposable percutaneous nephrolithotomy (PCNL) set that we named the 'Economical One-shot PCNL Set' (Ecoset), which consists of a single 30-F dilator, 30-F sheath, and 8-F polyurethane dilator, as use of a 'one-shot' dilatation technique during PCNL is becoming widespread. PATIENT AND METHODS The medical records of 42 patients with kidney stones who had undergone 'one-shot' PCNL from February 2014 to June 2016 were retrospectively reviewed and analysed. Demographic data, as well as the stone size, radiation exposure time, operation time, hospitalisation duration, rate of treatment success and complications, were recorded. RESULTS The mean (SD, range) age of the patients was 44.43 (16.54, 11-72) years. The mean (SD) stone size was 35.12 (17.53) mm. The mean (SD) operation time was 54.58 (22.24) min. The mean (SD) fluoroscopic screening time was limited to 154.72 (117.48) s. Treatment success was achieved in 32 (76%) patients. The mean (SD) hospital stay was 3.09 (0.75) days. None of the patients had any major complications. Bleeding requiring blood transfusion was required in three patients. The cost of a disposable dilatation set for a single PCNL operation with a balloon set, a standard Amplatz set, or an Ecoset is ∼$137, $120, or $27 (American dollars), respectively. CONCLUSIONS The one-shot dilatation technique using the Ecoset for PCNL can be feasibly, safely, and effectively performed in almost every adult patient. The Amplatz dilator set and balloon dilator set have the disadvantage of relatively high cost, whereas the Ecoset is the cheapest 'disposable set' that can be used during PCNL surgery.

Abstract
Micropercutaneous nephrolithotomy (microperc) is a recently introduced percutaneous nephrolithotomy (PNL) technique that has the smallest tract size. The absence of an amplatz sheath during the microperc technique is a fundamental difference that distinguishes it from all other types of PNL (standard, mini, ultramini). Increasing of the intrarenal pelvic pressure (IPP) was demonstrated by the authors in adult patients but this problem may be even more serious in pediatric patients. Previously, the authors defined the use of a 14 gauge angiocath needle and sheath (microsheath) during microperc surgery for pediatric patient to reduce the IPP. In this novel technique, a second angiocath is used to access the renal collecting system to drain fluid during surgery. This technique is more effective in reducing IPP during microperc, especially in pediatric patients.

Abstract
PURPOSE We aimed to evaluate the role of kidney injury molecule-1 (KIM-1) in determining the intervals between shockwave lithotripsy (SWL) sessions. PATIENTS AND METHODS This was a prospective, controlled study. It included 40 patients with unilateral kidney stones and 40 healthy persons of a similar age group as controls. The patients' midflow urine samples were collected before SWL and 1 hour, 1 day, 1 week, and 1 month after the procedure. RESULTS The average age in the SWL and control groups was 45 ± 14 and 39 ± 15 years, respectively (P = 0.336). The average KIM-1 value before SWL was 0.74 ± 0.35 ng/mL, which was significantly higher than that of the control group (0.51 ± 0.14 ng/mL) (P < 0.001). Similarly, the average values of the urine samples after SWL were higher than those of the control group (P < 0.001). When the KIM-1 values of the patients given SWL were compared within the group, the KIM-1 values 1 hour (1.06 ± 0.51) and 1 day (0.99 ± 0.67) after the procedure were statistically clearly higher than those before the procedure (P < 0.001) and statistically clearly higher than those of the control group (P = 0.005). The KIM-1 values 1 week and 1 month after the procedure were not significantly different than the preprocedure values (P = 0.652 and P = 0.747, respectively). CONCLUSION KIM-1 is a noninvasive biomarker that may be used to show renal damage because of stones and early-stage renal damage linked to SWL. In addition, post-SWL KIM-1 values may be used to determine the interval between SWL sessions.

Abstract
OBJECTIVE To compare outcomes of micro-percutaneous nephrolithotomy (PNL; microperc) with mini-PNL (miniperc) in the treatment of pediatric renal stones of sizes 10-20 mm. MATERIALS AND METHODS Patients aged <18 years who underwent PNL for renal stones of sizes 10-20 mm between August 2011 and March 2014 in 3 referral centers were reviewed retrospectively. Patients were evaluated in the following 2 groups: microperc (group 1) and miniperc (group 2). Demographics and perioperative parameters (fluoroscopy and operation time, hemoglobin drop, and stone-free and complication rates) were retrospectively analyzed. RESULTS A total of 119 patients were evaluated, including group 1 (n = 56) for microperc and group 2 (n = 63) for miniperc. We found mean stone sizes as 13.4 ± 3.4 and 14.8 ± 3.7 mm in the groups, respectively (P = .046). Mean operation and fluoroscopy times were 57.1 ± 31.2 minutes and 132.4 ± 92.5 seconds in the microperc group and 68.9 ± 36.7 minutes and 226.2 ± 166.2 seconds in the miniperc group, respectively (P = .110 and P <.001). Stone-free rates were similar in both groups (82.1% vs 87.3%; P = .433 and 92.8% vs 93.6%; P = 0673) on postoperative day 1 and at first-month follow-up. The mean hemoglobin drop in group 2 differed from that in group 1 significantly (P <.001). The difference of average hospitalization times was statistically significant (43.0 ± 15.4 vs 68.5 ± 31.7 hours; P <.001). CONCLUSION Our outcomes show that microperc may be preferred as an alternative to mini-PNL for the treatment of pediatric kidney stones of sizes 10-20 mm with comparable success and complication rates, as well as shorter hospitalization and fluoroscopy times.

Abstract
Varicoceles are the most common and treatable cause of male infertility. The pathophysiology of varicoceles primarily includes elevated temperature, adrenal hormone reflux, gonadotoxic metabolite reflux, altered testicular blood flow, antisperm antibody formation and oxidative stress. The diagnosis of a varicocele is mainly clinical. However, a Doppler ultrasound is used to obtain clinical data and to more accurately measure testicular size. Acoustic radiation force impulse (ARFI) is an additional technique to simultaneously show different areas with different densities in a colour-coded image and a B-mode or greyscale image. This can be used for structural analysis of testicular tissue and has become an additional method for detecting pathologic tissue alterations. We enrolled 30 patients who had clinically diagnosed with left varicoceles and male infertility (Group 1). All patients were evaluated by history taking, physical examination, a spermiogram and an endocrine profile. Thirty control patients (Group 2) were randomly chosen from patients who had applied to an andrology clinic for infertility; their physical examinations and laboratory results showed normal findings. Mean elastography results were significantly different between the groups, and significantly lower in patients who had varicoceles. The relationship between hormonal profiles and elastography parameters was calculated as statistically significant negative correlations between FSH and elasticity. Additionally, a negative correlation was determined between varicocele grade and elasticity of testes. In conclusion, our prospective study showed that ARFI imaging may be more useful than palpation for determining early damage of testicular structure by varicoceles.

Abstract
To investigate the effect of carvacrol (CAR) on methotrexate (MTX)-induced testis damage in rats. Twenty-four male rats were equally divided into three groups: group I control treatment; group II MTX-treated; group III MTX + CAR-treated. A single dose of CAR was administered intraperitoneally to group III on the first day of the experiment and a single dose of MTX was administered intraperitoneally to groups II and III on the second day of the experiment. The total duration of the experiment was 8 days. Blood samples and testis tissue were obtained from each animal for the measurement of malondialdehyde (MDA), Total oxidant status (TOS), Total Antioxidant Status (TAS), and Oxidative stress index (OSI). Light microscopy was used to complete the histopathological examination of testis specimens from each animal. Analysis of serum and testis sampled revealed that MDA, TOS and OSI levels were significantly greater in the group receiving MTX alone relative to the control treated animals while the TAS level was significantly reduced in the MTX group when compared with the control group. The administration of CAR was associated with significantly decreased MDA, TOS, and OSI levels and increased TAS levels relative to the rats treated with MTX alone. All of these quantitative values demonstrate that CAR alleviates deleterious effects of MTX on testicular tissue. Use of antioxidants such as CAR may protect germ cells against oxidative stress and apoptosis when used in combination with MTX.

Abstract
OBJECTIVE To present the outcomes of flexible ureterorenoscopy (F-URS) and laser lithotripsy for the treatment of calculi within pelvic ectopic kidney (PEK). PATIENTS AND METHODS We retrospectively reviewed the medical records of 26 patients with calculi in PEK treated with F-URS in 5 referral hospitals between 2010 and 2013. Patient demographics and stone characteristics (age, sex, body mass index, stone size, location, history of shock wave lithotripsy or kidney surgery), and perioperative measures (duration of operation, fluoroscopic imaging, and hospitalization and success and complication rates) were reviewed. RESULTS A total of 26 patients with mean age of 41.1 ± 15.8 years (7-72 years) were included in the study. The mean stone size was 17.0 ± 5.1 mm (10-28 mm). The mean procedure and fluoroscopy times were calculated as 52.1 ± 27.7 minutes (30-120 minutes) and 54.8 ± 48.9 seconds (10-180 seconds), respectively. The mean length of hospital stay was 2.7 ± 1.8 days (1-9 days). Treatment was deemed successful in 22 patients (84.6%). Ureteroscopy failed in 4 patients (15.4%) due to impaired passage of fragments (n = 3) or inability to reach the stone secondary to the location in an isolated lower calyx (n = 1). Minor postoperative complications were observed in 5 patients (19.2%; persistent hematuria [n = 1], fever [n = 1], renal colic [n = 2], and urinary tract infection [n = 1]). No severe complications or mortality occurred. CONCLUSION Our results suggest that F-URS is a safe and effective minimally invasive treatment modality for small- and medium-sized stones in PEK.

Abstract
PURPOSE The purpose of this preliminary study was to prospectively evaluate the diagnostic performance of acoustic radiation force impulse (ARFI) imaging for differentiating benign lesions from malignant renal tumours. MATERIALS AND METHODS Sixty patients with renal lesions were enrolled in the study; mean patient age was 49.52 ± 20.46 years (range 1-83 years) and patients included 30 men and 30 women. Lesions were categorised as benign (n = 19), malignant (n = 36) and infectious (n = 5) in origin. The shear wave velocities (SWVs) of the tumours and the intact parenchyma were determined by ARFI quantification, and the differences in the SWVs were compared among groups. The final diagnoses were determined via pathologic (n = 33), clinical (n = 13) and imaging findings (n = 14). The SWV values of the renal tumours were analysed according to the final diagnoses. RESULTS The mean SWV value of the normal renal parenchyma was significantly different from that of all other lesions (p < 0.01). There was a significant difference between the SWV values of benign renal lesions including haematomas and the malignant renal lesions (p = 0.033). However, the SWV values of the infectious lesions and leiomyoma corresponded well with the malignant lesions. A Receiver operating characteristic (ROC) analysis demonstrated a cut-off value of 2.34 m/s between benign and malignant lesions, while sensitivity and specificity were determined to be 88 and 54 %, respectively. CONCLUSION ARFI elastography with ARFI quantification may be useful for differentiating benign renal lesions from malignant renal tumours.

Abstract
The aim of this study was to investigate the effectiveness and reliability of the micro-percutaneous nephrolithotomy (PNL) method for the management of kidney stones. We performed a retrospective analysis of 136 patients (140 renal units) who underwent micro-PNL for renal stones between September 2011 and February 2013 in four referral hospitals in Turkey. The selection of treatment modality was primarily based on factors such as stone size and location. In this study, we analyzed patient- and procedure-related factors. The mean age of patients in this study was 28.7 ± 20.6 (1-69) years, and the mean stone size was 15.1 ± 5.15 (6-32) mm. Conversion to mini-PNL was required in 12 patients. All interventions were performed with the patient in the prone position, except for the 3-year-old patient with the pelvic kidney who was placed in the supine position. The mean hospital stay was 1.76 ± 0.65 (1-4) days, and the mean drop in the hemoglobin level was 0.87 ± 0.84 (0-4.1) mg/dL. One of our patients required transfusion. Ureteral J stent was implanted in nine (6.43 %) patients because of residual stones. Seven (6.43 %) patients complained of postoperative renal colic which was managed conservatively. Abdominal distension related to extravasation of the irrigation fluid was observed in three patients (2.19 %). There were no other postoperative complications. An overall success rate of 82.14 % was achieved. Micro-PNL can be effectively and safely used for small and moderate kidney stones resistant to shock wave lithotripsy or as an alternative to other minimally invasive treatment methods.
