RESUMEN
OBJECTIVE: The aim of the present prospective clinical study was to investigate the possible effect of endothelial dysfunction in urolithiasis. METHODS: The study included 92 patients older than 18 years. The patients were divided into 4 groups with 23 patients each as group 1: metabolic sydrome (MetS) (-) stone disease (SD) (-), group 2: MetS (-) SD (+), group 3: MetS (+) SD (-) and group 4: MetS (+) SD (+). C-reactive protein, homocysteine, uric acid, and creatinine levels were evaluated between the groups. Endothelial (dys)function was evaluated based on the brachial artery flow-mediated dilation (FMD) measurement. RESULTS: The mean age was 41.9 ± 10.2 (range, 18-62) years. Mean FMD value was 15.9 ± 18.2% (range, 24.0-68.5%). A strong significant difference was found between group 1 and 2 (p < .001); group 1 and 3 (p < .001) and group 1 and 4 (p < .001) with regard to FMD. CONCLUSION: These results suggest that endothelial dysfunction plays an important role in the pathogenesis of urolithiasis in patients with MetS.

INTRODUCTION: We aimed to compare extracorporeal shockwave lithotripsy (ESWL) and retrograde intrarenal surgery (RIRS) in pediatric patients with ≤2 cm renal pelvis and proximal ureteral stones. METHODS: Medical records of 165 pediatric patients who underwent shockwave lithotripsy (SWL) or RIRS for upper urinary system stones up to 2 cm between January 2014 and December 2018 were retrospectively reviewed. After exclusions, the remaining 130 patients included 73 in the SWL group and 57 in the RIRS group. The groups were compared for demographic features, stone characteristics, operative data, success, and complications. RESULTS: The mean stone volume was 308 ± 85 (54-800) and 336 ± 96 (60-720) mm3 in SWL and RIRS groups, respectively (P = 0.46). There were no significant differences in success rates (60% vs. 70%, SWL and RIRS), auxiliary treatment rates (16.4% vs. 14%), and complication rates (26% vs. 24.5%). The number of active procedural sessions and number of anesthesia sessions was higher in the RIRS group (P < 0.001 and P < 0.001, respectively), while the procedural time and anesthesia time were higher in the SWL group (P < 0.001 and P < 0.001, respectively). Stone size was found to be an independent success predictive factor for both the treatment modalities. CONCLUSIONS: Both SWL and RIRS have similar success, complication, and auxiliary treatment rates. RIRS was superior in terms of total procedure and anesthesia durations, while SWL was superior in terms of numbers of anesthesia sessions and active procedure sessions. As both have similar success rates, the more minimally invasive SWL should be chosen for pediatric upper urinary system stones of less than 2 cm size.
RESUMEN
OBJECTIVES: To compare the efficacy, safety and cost of combinations of perineal pudendal nerve block + periprostatic nerve block and intrarectal local anesthesia + periprostatic nerve block with the standard technique (periprostatic nerve block). METHODS: The study was designed as a randomized prospective controlled trial. Patients with elevated serum prostate-specific antigen values (prostate-specific antigen ≥4 ng/mL) and/or abnormal digital rectal examination findings were included in the study. Patients with anorectal diseases, chronic prostatitis, previous history of prostate biopsy and anorectal surgery were excluded from the study. A total of 148 patients (group 1 [periprostatic nerve block], n = 48; group 2 [intrarectal local anesthesia + periprostatic nerve block], n = 51; group 3 [perineal pudendal nerve block + periprostatic nerve block], n = 49) were included in the final analysis. Pain during insertion and manipulation of the transrectal ultrasound probe was recorded as visual analog scale 1, pain during penetration of the biopsy needle into the prostate and sampling was recorded as visual analog scale 2, and pain during the entire procedure recorded as visual analog scale 3. RESULTS: The mean visual analog scale 1 score was significantly lower in group 3, when compared with group 1 and group 2 (P < 0.001). There was no significant difference between the groups in terms of the mean visual analog scale 2 score. The mean visual analog scale 3 score was significantly lower in group 3 when compared with other groups (P < 0.001). The total cost for transrectal ultrasound-guided biopsy in the intrarectal local anesthesia + periprostatic nerve block group was significantly higher than the other two groups. CONCLUSIONS: The combination of perineal pudendal nerve block and periprostatic nerve block provides more effective pain control than intrarectal local anesthesia plus periprostatic nerve block and periprostatic nerve block alone, with similar complication rates and without increasing cost.

PURPOSE: We aimed to compare the outcomes of supine and prone miniaturized percutaneous nephrolithotomy (m-PNL) in the treatment of lower pole, middle pole and renal pelvic stones. MATERIALS AND METHODS: 54 patients who performed supine m-PNL between January 2017 and March 2018 and 498 patients who performed prone m-PNL between April 2015 and January 2018 were included in the study. Of the 498 patients, 108 matching 1: 2 in terms of age, gender, body mass index, American Association of Anesthesiology score, stone size, stone localization and hydronephrosis according to the supine m-PNL group were selected as prone m-PNL group. The patients with solitary kidney, upper pole stone, urinary system anomaly or skeletal malformation and pediatric patients (<18 years old) were excluded from the study. The success was defined as 'complete stone clearance' and was determined according to the 1st month computed tomography. RESULTS: The operation time and fluoroscopy time in supine m-PNL was significantly shorter than prone m-PNL group (58.1±45.9 vs. 80.1±40.0 min and 3.0±1.7 min vs. 4.9±4.5 min, p=0.025 and p=0.01, respectively). When post-operative complications were compared according to the modified Clavien-Dindo classification, overall and subgroup complication rates were comparable between groups. There was no significant difference between the groups in terms of the success rates (supine m-PNL; 72.2%, prone m-PNL; 71.3%, p=0.902). CONCLUSIONS: Supine m-PNL procedure is more advantageous in terms of operation time and fluoroscopy time in the treatment of lower pole, middle pole and renal pelvic stones.

INTRODUCTION: Durasphere® EXP (DEXP) is a compound of biocompatible and non-biodegradable particles of zirconium oxide covered with pyrolytic carbon. The aim of this study is to evaluate the durability of off-label use of DEXP in the treatment of primary vesicoureteral reflux in children. MATERIALS AND METHODS: Patients who underwent subureteric injection of DEXP for the correction of primary VUR were retrospectively reviewed . Patients aged >18 years as well as those who had grade-I or -V VUR, anatomic abnormalities (duplicated system, hutch diverticulum), neurogenic bladder or treatment refractory voiding dysfunction were excluded. Radiologic success was defined as the resolution of VUR at the 3rd month control. Success was radiographically evaluated at the end of the first year. RESULTS: Thirty-eight patients (9 boys, 29 girls; mean age, 6.3±2.7 years) formed the study cohort. Forty-six renal units received DEXP (grade II: 22; grade III: 18; grade IV: 6). Mean volume per ureteric orifice to obtain the mound was 0.70±0.16mL. First control VCUG was done after 3 months in all patients. After the first VCUG, 6 patients had VUR recurrence. Short-term radiologic success of DEXP was 84.2%. Rate of radiologic success at the end of the first year was 69.4% (25/32). Lower age (p:0.006) and lower amount of injected material (p:0.05) were associated with higher success rates at the end of 1 year. CONCLUSION: This is the first study to assess the outcomes of DEXP for treatment of primary VUR in children. After 1 year of follow-up, DEXP had a 69.4% success rate.

PURPOSE: Premature ejaculation is considered the most common type of male sexual dysfunction. Hormonal controls of ejaculation have not been exactly elucidated. The aim of our study is to investigate the role of hormonal factors in patients with premature ejaculation. MATERIALS AND METHODS: Sixty-three participants who consulted our outpatient clinics with complaints of premature ejaculation and 39 healthy men as a control group selected from volunteers were included in the study. A total of 102 sexual active men aged between 21 and 76 years were included. Premature ejaculation diagnostic tool questionnaires were used to assessment of premature ejaculation. Serum levels of follicle stimulating hormone, luteinizing hormone, prolactin, total and free testosterone, thyroid-stimulating hormone, free triiodothyronine and thyroxine were measured. RESULTS: Thyroid-stimulating hormone, luteinizing hormone, and prolactin levels were significantly lower in men with premature ejaculation according to premature ejaculation diagnostic tool (p=0.017, 0.007 and 0.007, respectively). Luteinizing hormone level (OR, 1.293; p=0.014) was found to be an independent risk factor for premature ejaculation. CONCLUSIONS: Luteinizing hormone, prolactin, and thyroid-stimulating hormone levels are associated with premature ejaculation which was diagnosed by premature ejaculation diagnostic tool questionnaires. The relationship between these findings have to be determined by more extensive studies.

PURPOSE: To compare adjuvant hyperthermic intravesical chemotherapy (HIVEC) with mitomycin C and standard Bacillus Calmette-Guerin (BCG) therapy in terms of oncological outcomes and adverse events in patients with high-risk non-muscle-invasive bladder cancer (NMIBC). MATERIALS AND METHODS: The data of patients with high-risk papillary NMIBC treated with adjuvant intravesical BCG instillations or HIVEC in our institution between June 2017 and August 2022 were analyzed retrospectively. Twenty-four patients who received HIVEC were matched 1:1 with patients receiving BCG therapy based on tumor characteristics (tumor stage and grade), age, gender, smoking status, and the number of tumors (single or multiple). HIVEC and standard BCG treatments were compared in terms of recurrence-free survival (RFS), progression-free survival (PFS), and adverse events. RESULTS: Forty-eight patients (24 in the BCG group and 24 in the HIVEC group) were included in the study. The median follow-up times of the BCG and HIVEC groups were 32 [interquartile range (IQR): 28.0-47.8] and 28 (IQR: 16.7-41.8) months, respectively (p = 0.11). There was no significant difference between the groups in terms of the 24-month RFS (BCG 83% vs HIVEC 88%, p = 0.64) and the 24-month PFS (BCG 100% vs HIVEC 94%, p = 0.61). Regarding the safety profile, at least one adverse event occurred in 13 (54%) of the patients in the BCG group and 12 (50.0%) of those in the HIVEC group (p = 0.77). CONCLUSION: This study demonstrated that HIVEC with mitomycin C has a similar oncological efficacy and safety profile to standard BCG therapy in high-risk NMIBC.

Aim: To evaluate the oncological and functional outcomes of 167 patients who underwent laparoscopic radical prostatectomy (LRP). Materials and Methods: The retrospective study included 167 patients who were treated with LRP due to clinically localized prostate cancer between January 2007 and April 2012. Most of the patients were treated with the extraperitoneal approach. Preoperative evaluations included age, serum prostate-specific antigen (PSA) level, and biopsy Gleason score. Perioperative evaluations included duration of operative time and anastomosis time, blood loss (milliliter), and complications. Postoperative evaluations included length of hospital stay and catheterization time. Continence and erectile function were evaluated both pre- and postoperatively. The patients who used no pads or no more than one pad daily and the ones who had only a few urine leakages on effort or exertion were accepted as continent. Postoperative potency was defined as the ability to achieve sexual intercourse with or without the use of PDE-5 inhibitors. Results: Mean age and mean operative time were 62.4 ± 6.0 years and 220.5 ± 45.6 minutes, respectively. Mean anastomosis time was 35.6 ± 9.8 minutes. Mean serum PSA level and mean Gleason score were 17.5 ± 9.97 ng/mL and 6.16 ± 0.42, respectively. Pelvic lymphadenectomy was performed in 94 patients and nerve-sparing procedures in 61 patients. The pathological analysis revealed positive surgical margin in 35 patients (20.9%). Bilateral and unilateral nerve-sparing LRP procedures were performed in 51 (30.5%) and 10 (6%) patients, respectively. At 12 months after surgery, 3 (1.8%) patients were using 2 or more pads per day, 19 (26.4%) patients were satisfied with erection, hardness, and duration of intercourse, and 9 (12.5%) patients had an erection with insufficient hardness and duration. Conclusion: LRP is an acceptable method in localized prostate cancer due to its perioperative and early postoperative results.

PURPOSE: To compare different treatment approaches in patients with failed ureteral access sheath placement during first flexible ureterorenoscopy (f-URS) session. METHODS: Patients with kidney stones measuring 1-2 cm, presented to our urology clinic between September 2020 and September 2021, were included in the study for evaluation. The study was designed prospectively (Clinical-Trials number NCT05911945). Patients were randomized into two groups, in case of a failed ureteral access sheath placement during the first f-URS session. In group 1, JJ stent was placed for dilation and second session of f-URS was planned. In group 2, mini percutaneous nephrolithotomy (mPNL) was performed in the same session. RESULTS: Twenty-four patients were included in each group. Pre-operative demographic data and stone characteristics of the patients in each group were comparable. Operation time, fluoroscopy time, and hospital stay were significantly higher in the mini-PNL group. When SF-36 values were compared, physical function, pain, role limitation, and general health value scores were improved in both groups after treatment. The improvement in physical function and pain parameters was statistically significant in the mPNL group. In patients with failed ureteral access sheath placement, placing a JJ stent for dilation and postponing f-URS for 4-6 weeks provides the advantages of low hospitalization time for each admission, shorter fluoroscopy and operation time. CONCLUSIONS: Performing mPNL in the same session, results in better improvements in SF-36 parameters such as pain and physical function compared to f-URS. The success and complication rates of the two procedures were comparable.

OBJECTIVE: To evaluate whether renal parenchymal thickness (RPT) has an effect on the outcomes of percutaneous nephrolithotomy (PNL). METHODS: We performed a retrospective analysis of 144 patients with lower pole and/or renal pelvic stones who underwent PNL. The relationship between RPT and peri- and postoperative measures was evaluated. RESULTS: The average age was 45.94 ± 14.47 (15-76) years. The mean BMI was calculated as 27.47 ± 4.73 (16.9-44.9) kg/m(2). The mean stone burden was 293 ± 126 (150-800 mm(2)). The mean RPT was measured as 17.33 ± 5.32 (6-35) mm. No correlation was detected between the RPT and the operation or fluoroscopy times or the duration of hospitalization (p = 0.63, 0.52, 0.08, respectively). The mean drop in hemoglobin level was 1.45 ± 1.25 (0-9) g/dl. A negative correlation was detected between hemoglobin drop and RPT (p = 0.01, r = -0.23). However, the RPT was similar in patients who did or did not require a blood transfusion (p = 0.09). The RPT was found to have no impact on success rate (p = 0.4). CONCLUSION: The postoperative hemoglobin drop increases in parallel with the increase in RPT. However, no relationship was detected between the RPT and blood transfusion, overall success rate or any other perioperative parameters.

Robotic-assisted magnetic resonance imaging (MRI)/transrectal ultrasound (TRUS) fusion transperineal biopsy systems are one of the most debated and interesting subjects both in practice and in current urology literature. The comprehensive literature research was carried out in the PubMed/MEDLINE, Google Scholar, and Scopus databases using the terms "robotic transperineal prostate biopsy," "robot-assisted MRI/US fusion biopsy," "robot-assisted MRI/TRUS fusion biopsy," or "robotic targeted prostate biopsies." All article types were included in the study (n=343). Among these, articles in non-English languages, duplicate articles, review articles, guidelines, and book chapters were excluded from the study (n=325). Additionally, articles on In-bore biopsy and semirigid device techniques were also excluded from the study (n=5). A total of 13 original research studies (3 retrospective and 10 prospective nonrandomized studies; total number of patients=1844) performed with 2 diferent robotic-assisted transperineal biopsy platforms (iSR'obot™ MonaLisa, Biobot Surgical, Singapore; and Artemis™, Eigen,GRASS VALLEY, USA) were analyzed in detail. The overall cancer detection rates ranged from 51.2% to 73.7%, while the rates of detecting clinically significant (cs) prostate cancer (Pca) ranged from 23.0% to 52.7% in patients who had not been previously diagnosed with prostate cancer. Among the 1844 patients, only 2 individuals (0.01%) were diagnosed with urosepsis. Although the role of these devices in prostate biopsies is not completely clear, the robot-assisted transperineal prostate biopsy technique is an efective and safe procedure, with high rates of csPCa detection and acceptable rates of complications, especially in terms of urosepsis.
RESUMEN
Drainage catheters are used almost routinely to provide urinary drainage, prevent extravasation of urine, and create tamponade against bleeding after percutaneous nephrolithotomy (PNL). In the literature, there is no standardized approach to determining which type of catheter is superior. In this context, we aimed to comparatively analyze two different types of catheters (re-entry malecot catheter and nelaton catheter) in terms of success and complications, which we use for drainage after a PNL operation and which have very different costs. Patients who underwent PNL for kidney stones between January 2018 and October 2022 were included in the study. The data of a total of 148 patients who had a 16-F reentry malecot nephrostomy catheter or a 16-F nelaton catheter were analyzed. In addition to the demographic characteristics of the patients, stone characteristics, operative data, hospitalization time, analgesia requirement, hemoglobin exchange, amount of blood transfusion, and postoperative data (success and complications) were comparatively evaluated. The current unit price for a reentry malecot and a nelaton catheter is 4.7 United States dollars (USD) and 0.11 USD, respectively. There were a total of 148 patients in the study, 63 of whom were nelaton catheters and 85 were reentry malecots, and the mean age was 39.95 ± 13.28 years. There was no statistically significant difference between preoperative stone sizes and residual stone rates according to the groups. In addition, there was no statistically significant difference between the groups in terms of access site and stone localization. There was no significant difference between the groups in terms of complication rates according to the Clavien-Dindo classification, Hb levels, blood transfusion rates, operation times, or hospitalization times. In conclusion, if a second procedure is planned, a reentry malecot catheter may be preferred. Apart from this situation, nelaton catheters should be preferred because they are similar to reentry catheters in terms of effectiveness, and side effects and are more economical than reentry catheters in terms of cost.

BACKGROUND AND AIM: Some patients with high-risk non-muscle-invasive bladder cancer (NMIBC) are unable to receive adequate BCG instillations due to intolerance. In this study we aimed to investigate the efficacy and tolerability of hyperthermic intravesical chemotherapy (HIVEC®) treatment using Mitomycin C (MMC) in BCG-intolerant NMIBC patients. METHODS: Retrospectively collected data from a total of 22 high-risk papillary NMIBC patients who received adjuvant HIVEC therapy for BCG intolerance were analyzed. The primary outcomes of the study were recurrence-free survival (RFS), time to recurrence, progression-free survival (PFS), and time to progression following initial TURB. Detection of histologically confirmed urothelial carcinoma during follow-up was considered as recurrence, while detection of muscle-invasive disease was defined as progression. The secondary outcome was adverse events of HIVEC treatment. RESULTS: The median follow-up was 32.2 (IQR: 17.8-42.8) months. The RFS and PFS rates were 81.8% and 95.4%, respectively. The mean time to tumor recurrence and progression was 29.2 ± 14.3 and 16.7 months, respectively. Adverse events occurred in 50% of patients, and 95% of adverse events were mild to moderate. CONCLUSION: This study demonstrated that adjuvant HIVEC with MMC is an effective and safe alternative bladder sparing treatment in BCG intolerant high risk papillary NMIBC patients.

UNLABELLED: Study Type--Prognosis (cohort) Level of Evidence 2b. What's known on the subject? and What does the study add? The presence of metabolic syndrome is associated with development of kidney stones and an increase in the stone-recurrence rate. However, studies reporting long-term results of percutaneous nephrolithotomy (PCNL) in metabolic syndrome are lacking. The present study showed that metabolic syndrome was associated with worsening renal function at long-term follow-up and the stone-recurrence rate recurrence after PCNL in patients with metabolic syndrome was 3.2-fold higher compared with the control group. OBJECTIVE: ⢠To investigate the impact of metabolic syndrome on long-term kidney function and stone recurrence rates after percutaneous nephrolithotomy (PCNL). PATIENTS AND METHODS: ⢠In all, 73 patients with metabolic syndrome who underwent stone analysis and had a minimum follow-up of 12 months after PCNL were reviewed. ⢠In addition, 73 patients without any metabolic syndrome components who had undergone PCNL and were followed-up for at least 12 months were included in the study as the control group. ⢠These control group patients were selected from 226 patients who were matched with the patients with metabolic syndrome using a 1 : 1 ratio. The matching parameters were age, gender and stone size. RESULTS: ⢠Stone analyses showed that calcium oxalate monohydrate (52.0%) and uric acid (21.9%) were most common among patients with metabolic syndrome, whereas calcium oxalate monohydrate (76.7%) was the most common stone type in the control group. ⢠Stone recurrences occurred with a mean (sd, range) of 36.1 (21.3, 12-109) months follow-up in 26 patients (41.9%) and 12 patients (18.9%) in the metabolic syndrome and control groups, respectively (P = 0.003). ⢠While estimated glomerular filtration rate was decreased from 87.8 to 66.6 mL/min/1.73 m(2) in the metabolic syndrome group, it changed from 96.4 to 91.2 mL/min/1.73 m(2) in control group at long-term follow-up. CONCLUSIONS: ⢠The most frequent stone type was calcium oxalate monohydrate in patients with or without metabolic syndrome. ⢠In patients with metabolic syndrome who underwent PCNL, the stone recurrence rate was >40%. ⢠Metabolic syndrome is associated with worsening renal function at long-term follow-up.

Aim: To determine the advantages and disadvantages of both methods by comparing classic circumcision methods with circumcision methods assisted by ring instruments. Material-Methods: Only studies that compared open procedures and ring devices for male circumcision were included. A total of 6226 patients were examined in 14 studies. The methodological quality of RCT was evaluated using Cochrane collaboration's tools. The Review Manager software statistical package was used to analyze the ORs for dichotomous variables and the mean differences for continuous variables. The proportion of heterogeneity across the studies was tested using the I 2 index. Potential publication bias was assessed by identifying the presence of visual asymmetry/symmetry with funnel plot studies. Results: There were 1812 patients in the open circumcision group and 4414 patients in the ring groups. In total, there was no difference identified between the groups. The open procedure had an advantage compared to the Plastibell subgroup for hemorrhage, while in the other two subgroups, the ring instrument groups had the advantage. Statistically significant in favor of ring devices was found in operating time.There was no difference between the groups for early (postoperative) pain scores. For late-period pain scores, differences with statistical significance were identified in favor of ring devices both in subgroups and in total. For satisfaction, apart from one study in the PrePex group, statistical significance was obtained in favor of ring devices for the other subgroups and in total. Conclusion: The main factors in favor of the use of ring instruments for circumcision are the short total surgical duration, not requiring advanced surgical experience, ease of learning and application, and patient relative satisfaction rates. However, it is a condition to know open circumcision methods and to have experience of this surgery for use in situations with hemorrhage complications, mainly, and without ring instruments of appropriate size.
RESUMEN
INTRODUCTION: Outbreaks caused by microorganisms contaminating the inside of rigid ureteroscopes are extremely rare. Some of these outbreaks, especially those caused by multidrug-resistant (MDR) infections, can cause serious problems, even death. Among these serious infections, we have no data about Klebsiellapneumoniae outbreaks caused by rigid ureteroscopes and their management and consequences.

PURPOSE: To investigate the effects of combined tadalafil and testosterone usage on oxidative stress, DNA damage and MMPs in testosterone deficiency. METHODS: Fifty rats were randomly divided into 5 groups (group-1: sham group-placebo, group-2: bilateral orchiectomy (ORX), group-3: bilateral ORX+tadalafil, group-4: bilateral ORX+testosterone, group-5: bilateral ORX+tadalafil+testosterone). Group-3 received tadalafil (5mg/kg/day, oral). Group-4 was administered testosterone undecanoate (100mg/kg i.m., single dose). Group-5 was administered a combination of tadalafil and testosterone undecanoate. All groups were compared with regard to serum nicotinamide adenine dinucleotide phosphate oxidase-4 (NOX-4), total thiol, matrix metalloproteinase-2 (MMP-2), MMP-3 and MMP-9, tissue inhibitor of metalloproteinases-1 (TIMP-1) and TIMP-2 and 8-hydroxy-2-deoxy guanosine (8-OHdG) levels. RESULTS: Total thiol levels of group-2 were significantly lower than the other groups and thiol levels were higher in group-1 and group-5 than in the other groups. NOX4, MMP2 and 9 levels in group-2 were higher than in the other groups. MMP-9 levels in group-5 were lower than in groups 3 and 4 (p=.001). The level of 8-OHdG in groups 2 and 3 was higher than in the other groups (p=.001). In correlation analysis, 8-OHdG, MMP2, and 9 levels were negatively correlated with total thiol, whereas NOX4 and 8-OHdG levels were positively correlated with MMPs values. CONCLUSIONS: The combination of testosterone with PDE-5 inhibitor suppresses MMP-9 levels and increases total thiol levels better than testosterone alone and tadalafil alone. Therefore, testosterone can be considered for use with PDE-5 inhibitor from the initial stage in case of testosterone deficiency.
