RESUMEN
PURPOSE: We aimed to find out if there was any difference between intramuscular and intravenous administration of lornoxicam in terms of efficacy and side effects. MATERIALS AND METHODS: This study was a single-blind parallel-group randomized clinical trial. A total of 51 patients who were diagnosed with acute renal colic at our clinic were included in the study. Pain severity prior to treatment was rated using the Visual Analogue Scale (VAS). Patients were randomized into 2 groups: Group 1 (n = 27) received intramuscular 8mg lornoxicam and Group 2 (n=24) received intravenous 8mg lornoxicam. Pain severity was reassessed 30 minutes after the treatment. Pre- and post-treatment VAS scores and the mean changein the VAS scores of the 2 groups were statistically compared. RESULTS: The mean VAS scores decreased significantly from 7.65 to 2.07 in Group 1, from 7.96 to 1.38 in Group 2, and from 7.79 to 1.75 in total (P < 0.001). No statistically significant difference was observed between Groups 1 and 2 in terms of VAS score reduction (P = 0.128). None of the patients suffered any side effects except for 1 (2%) patient who had dyspepsia. CONCLUSION: Parenteral lornoxicam provides significant pain relief in patients with acute renal colic. However, no significant difference was found between intramuscular and intravenous administration in terms of analgesic efficacy.

This study analyzed the impact of an immediate second transurethral resection of bladder tumor (TURBT) protocol on residual tumor status at the initial TURBT session and the recurrence rate in the primary resection area. We prospectively evaluated and randomized 47 consecutive patients who underwent TURBT sessions for bladder cancer. In accordance with the inclusion criteria, of the 47 consecutive patients, 19 (Group I) underwent immediate second resection of the tumor bed after complete TUR and 28 (Group II) did not. After standard TURBT, Group I underwent a second cystoscopy and resection of the bed of the tumor or an ignored tumor, which was performed by a different urologist. After 4-6 weeks, delayed second TURB was performed, and all pathological results were evaluated. Tumors were detected in two patients during the immediate second resection. Of these, one was a misdiagnosed tumor, whereas the other was diagnosed at the bed of the tumor by pathological examination. Tumors were detected in nine patients at the delayed second TURB, of which only one was part of Group I, while the others were part of Group II (p = 0.04). The results of this study demonstrated that residual tumors may remain after initial TURB, either in the tumor bed or in a different location within the bladder. Although this was a pilot study enrolling only a small number of patients, our initial results supported the assertion that immediate second resection can be an alternative to standard second TURBT.

OBJECTIVE: To investigate the effectivity of 4.5F ultrathin ureteroscope (UT-URS) without any need for active or passive dilation in the treatment of adult patient population in whom ureteral orifices cannot be engaged using conventional URS. MATERIALS AND METHODS: Among a total of 512 adult patients who had undergone URS between April 2012 and November 2015 in our department for diagnostic or therapeutic purposes, 43 (8.4%) patients required ureteral dilation because we could not engage ureteral orifice. In adult patients in whom we could not engage ureteral orifice with 7.5F and 8F semirigid URS, we tried to complete the operation using 4.5F UT-URS without resorting to dilation. Age and gender of the patients, indication for operation, stone size, location, operative times, laterality of stone(s), stone-free rates, length of hospital stay, and complications were recorded. RESULTS: Mean age of the patients was 34.5 ± 11.2 (21-66) years. The patients had undergone operations for ureteral stone (n = 39), unexplained hydronephrosis (n = 2), and ureteral stenosis (n = 2). Mean stone size was 8.2 ± 2.3 (4-18) mm. Mean operative time was 64.2 ± 13.5 minutes. In 37 of 39 patients, a complete stone-free rate (94.8%) was achieved. Mean length of hospital stay was 8.9 ± 5.8 hours. CONCLUSION: It has been demonstrated that in an adult patient population in whom ureteral orifices cannot be engaged using conventional URS, ureteral access could be achieved with 4.5F UT-URS without any need for dilation. At the same time, use of 4.5F UT-URS resulted in an acceptable treatment success and lower complication rates in most of these patients without the need for a second session.

This study aims to investigate the role of urinary biomarkers in the determination of the potential risks of renal parenchymal tubular damage in adult patients who underwent percutaneous nephrolithotomy (PNL) with the indication of renal stone. A randomized and prospective controlled study was performed between June and December 2013. We enrolled 29 consecutive patients with renal calculi > 2 cm and who underwent PNL, as well as 47 healthy control subjects. Urine samples, including 2 h before surgery, 2 and 24 h after surgery were collected from the patient group. Freshly voided urine samples were collected from the control group. Kidney injury molecule-1 (KIM-1), neutrophil gelatinase-associated lipocalin (NGAL), N-acetyl-glucosaminidase (NAG), and liver-type fatty acid binding protein (LFABP) levels were measured from these urine samples. The mean KIM-1/Cr value that measured 24 h after the operation was statistically significant, higher than its preoperative (preop) level (p = 0.045). A significant difference was detected between the mean preop and postoperative (postop) 24 h NAG/Cr values (p < 0.001). Also, postop 24 h NGAL/Cr levels were statistically significant, higher than its preop levels (p = 0.013). According to the comparison of preop and postop levels, an increase in LFABP/Cr values secondary to surgical intervention was observed without any statistically significant difference. Besides the LFABP/Cr levels do not change after percutaneous kidney surgery, KIM-1/Cr, NAG/Cr, and NGAL/Cr levels increase postop period, especially at 24 h. Further studies with a larger series and repeated measurements should be performed to clarify if they can be used to demonstrate renal damage after percutaneous surgery or not.

During infancy, the renal parenchyma and pelvicalyceal system are relatively fragile. Therefore, percutaneous nephrolithotomy for the management of renal stones in this age group is a challenging procedure for urologists. Herein, we present the uneventful management of bilateral renal stones using micropercutaneous nephrolithotomy (microperc) administered to a 7-month-old infant with recurrent urinary tract infections. In this paper, the advantages and disadvantages of the microperc procedure are discussed. As far as we know, our patient is the youngest case in whom the microperc procedure has been performed.

This study aimed to investigate the effectiveness and reliability of micro-percutaneous nephrolithotomy (micro-PNL) for the management of kidney stones in pediatric patients. This retrospective study included 24 infants that underwent micro-PNL for renal stones between March 2012 and April 2015. The inclusion criteria included: age younger than 2 years, stone size <20 mm, absence of urinary tract malformations and active infection, and no coagulopathy. Stone-free rates were assessed one month postoperatively by ultrasonography (USG) and kidneys, ureters, bladder (KUB) radiography. Complications were classified according to the Clavien classification system. The mean age of the patients was 15.8 ± 7.8 months (range, 8-23) and the mean stone size was 13.5 ± 3.84 mm. Intra-renal access was achieved using USG in 11 patients and KUB fluoroscopy in 13 patients. The operation time and fluoroscopic screening time were 53.7 ± 10.35 and 1.4 ± 0.9 min, respectively. The mean hospital stay was 2.5 ± 0.8 days, and the mean drop in the hemoglobin level was 0.51 ± 0.34 g/dL. Bleeding requiring blood transfusion was not observed. A ureteral J stent was implanted perioperatively in four patients because of stone burden. Four patients complained of postoperative renal colic (Clavien grade 1) and postoperative fever was observed in two patients. Definitive success rates were as follows: the stone-free rate was 83.3% (n = 20) and residual fragments were observed in four patients.

Pelvic kidney stones remain a unique challenge to the endourologists. Treatment options include open surgery, extracorporeal shockwave lithotripsy, percutaneous nephrolithotomy (PNL), retrograde intrarenal surgery, and laparoscopy assisted PNL (LA-PNL). As a minimal invasive option, LA-PNL can decrease the risk for bowel and major vessel injury. Here, we describe our experience using the LA-PNL procedures with different combinations, to treat kidney stones in multiple patients with a pelvic ectopic kidney (PEK). Eight patients, with PEK, kidney stones, and no other treatment choice, but open surgery, were included in the study. Two different laparoscopic techniques such as mesocolon dissection and transmesocolic, and four different percutaneous procedures such as standard-PNL, mini-PNL, micro-PNL, and a PNL through the renal pelvis were used for stone extraction in these patients. The mean age of patients was 25.6 ± 12.9 years and mean stone size was 524.1 ± 430.3 mm(2). Mean operation time was 150.5 ± 40.0 (77-210) min which was composed of retrograde catheterization (14.8 ± 2.9 min), laparoscopic procedure (48.7 ± 20.6 min) and PNL procedure (86.8 ± 31.1 min). Residual stones were seen in two patients (no additional treatment was need), while a 'stone-free' procedure was achieved in six patients (75.0 %). On the post-operative first month visit, a stone was observed on radiological examinations in only one patient (87.5 % stone-free). Mean hospitalization time was 2.8 ± 0.9 days. No perioperative or post-operative complication was observed in all patients. LA-PNL surgery is a safe and effective option for treatment of PEK stones, and has several alternative approaches.

The objective of the study is to evaluate the effectiveness and safety of miniaturized percutaneous nephrolithotomy (mini-PNL) method in infantile patients <3 years of age diagnosed with renal stones. We studied 48 renal units in 40 patients of infantile patients <3 years of age who underwent mini-PCNL at our institute. The mean age of the patients was 24.02 (5-36) months. The mean diameter of the stones was 22.3 mm (11-45 mm). Intrarenal access was achieved under fluoroscopic (n = 43) or ultrasonographic (n = 5) guidance under general anesthesia. A 20 Fr peel-away sheath, a 17 Fr rigid nephroscope and a pneumatic intracorporeal lithotripsy were used. Mean operative time for PNL was 85 (25-135) min. Mean fluoroscopy time was estimated as 3.7 min. The mean hospital stay was 4.3 days (2-10). Mean hemoglobin loss was 0.89 g/L (11.56-10.67) and three of the patients, including one case during the perioperative period, required blood transfusions. Colonic perforation developed in one case. In two patients, urinary drainage persisted for more than 24 h after withdrawal of the nephrostomy tube. Seven patients developed urinary tract infections (UTI). At the end of the postoperative first week, the stone-free rate was estimated to be 81.2 %. In conclusion, for percutaneous management of renal stones in the infantile age group, mini-PNL is an applicable treatment modality that can be applied through small incisions. It has higher stone-free rates, shorter hospital stays, and excellent esthetic outcomes. In this age group especially, surgical exposure to hypothermia and radiation should be avoided.

The superficial cervical plexus block (SCPB) is utilized in pediatric patients to perform certain surgical procedures, but there is no evidence supporting its use in hemodialysis catheter placement. We evaluated the analgesic effectiveness, intraoperative complications, and patient satisfaction associated with SCPB for pediatric patients in renal failure undergoing emergent dialysis catheterization. A total of 52 patients ranging from 1 to 17 years old that required emergent dialysis catheter placement and received SCPB were included in this study. During the catheterization, intraoperative pain scores, requirement for additional analgesia, catheterization access site, and intraoperative complications were recorded. The Children's Hospital of Eastern Ontario Pain Scale (mCHEOPS) was used to determine pain ratings during skin puncture with the needle, skin dilatation, and securing the catheter with stitches. The patients had an average age of 8.46 ± 5.3 years. The preferred catheterization entry site was through right internal jugular vein, which was achieved in 80.7% of patients. However, 19.3% of patients required access through the right subclavian vein. The average mCHEOPS score during skin puncture was 1.4 ± 0.5, and the mean mCHEOPS score was 2.3 ± 0.6 for skin dilatation. Finally, the average mCHEOPS score while securing the catheter with stitches was 1.3 ± 0.4. No patient required fentanyl for additional analgesia. No intraoperative complications occurred. The benefits gained from using SCPB performed by an experienced anesthesiologist for hemodialysis catheter placement include providing sufficient analgesia and optimal surgical conditions while avoiding the complications associated with general anesthesia for pediatric patients with renal failure.

AIM: To evaluate the possible protective effect of pomegranate extract (PE) on rats following renal ischemia-reperfusion (I/R) injury. MATERIALS AND METHODS: Twenty-four Wistar rats were divided into three groups. Sham group underwent laparotomy then waited for 45 minutes without ischemia. I/R group were subjected to left renal ischemia for 45 minutes followed by 60 minutes of reperfusion. I/R + PE group were subjected to the same renal I/R as the I/R group were also given 225 mg/kg PE peroral 30 minutes prior to the ischemia. Malondialdehyde (MDA), total antioxidant capacity (TAC), total oxidant status (TOS), and oxidative stress index (OSI) were determined on the blood samples and kidney tissues. Histopathological analyses were conducted on the kidney tissues. RESULTS: Serum TAC levels were significantly decreased in I/R group when compared with S group (P = 0.001). Serum MDA levels were increased in I/R group; however, it was not statistically significant. In rat kidney tissues, TOS levels and OSI index were significantly increased after I/R injury, while TAC levels were decreased. In I/R + PE group, PE reversed the negative effects of I/R injury. PE pretreatment was effective in decreasing tubular necrosis score. CONCLUSION: PE pretreatment ameliorated the oxidative damage and histopathological changes occurring following renal I/R injury.
RESUMEN
INTRODUCTION: The pathophysiology of erectile dysfunction (ED) may be vasculogenic, hormonal, anatomical, neurogenic, drug-induced and/or psychogenic in origin. Neuropathic pain (NP) may facilitate ED, because it is frequently associated with anxiety, depression, and its drug, pregabalin, may also contribute ED. AIM: The objective of this study was to determine whether pregabalin treatment for patients with neuropathic pain promotes erectile dysfunction. METHODS: The study sample consisted of a total of 102 male subjects that were subdivided into three groups. Group 1 patients (n = 31) had a pre-existing diagnosis of NP and was treated with 300 mg/day of pregabalin for at least 3 months. Group 2 patients (n = 34) were diagnosed with NP for at least 3 months; however, neither were they treated with pregabalin nor did they received physical therapy throughout the study. Lastly, healthy age-matched control subjects comprised group 3 (n = 37). MAIN OUTCOME MEASURES: Patients in all groups completed the International Index for Erectile Function (IIEF) questionnaire. RESULTS: Mean age and mean body mass index did not differ significantly between each of the three groups. The cause of NP and the mean duration of having a diagnosis of NP did not differ significantly in groups 1 and 2. However, IIEF scores were significantly lower for group 1 when compared to group 2 in terms of erectile function, orgasmic function, overall satisfaction and total score. Yet groups 1 and 2 did not diverge significantly in the intercourse satisfaction and sexual desire scores. Overall IIEF scores for group 3 were significantly higher than those of group 2 except for mean erectile function scores. CONCLUSION: Taking pregabalin for the treatment of neuropathic pain poses an increased risk for developing ED in male patients. Thus, clinicians prescribing pregabalin to patients diagnosed with neuropathic pain should assess for ED before and during treatment with this medication.

AIM: We present our experience with micropercutaneous cystolithotripsy (mPCCL) using transillumination-guided access in children with bladder stones and evaluate the safety and efficacy of this procedure. METHODS: Twelve children who underwent mPCCL for bladder stone removal in our department between January 2011 and September 2013 were included in this study. Percutaneous access was performed using the transillumination technique. The chief complaint, age and sex of the patients, stone size, operative time, complications, stone-free rate, and stone composition as determined by radiography diffraction analysis were recorded. RESULTS: The mean age of the patients was 2.6 (1-7) years. One out of 12 patients was a girl. The mean stone size was 14 mm (7-32 mm). The mean mPCCL procedure time was 38.7 (15-65) minutes. The mean hospital stay was 1.4 (0.5-4) days. The stone-free rate after one mPCCL intervention was 91.6% and increased to 100% after two sessions of mPCCL. The notable complications were transient macroscopic hematuria in one patient, acute urinary retention in one patient, and the need for a second session of mPCCL in another patient. The stones were composed of calcium oxalate (3), ammonium acid urate (1), calcium phosphate (1), cystine (1), struvite (1), and unknown (5). CONCLUSION: Transillumination-guided mPCCL is a safe and effective technique, does not require the use of ionizing radiation, is technically easy, and is a minimally invasive alternative for the management of bladder stones. It has many advantages, especially in pediatric patients, such as decreased urethral injury, no need for postoperative catheter insertion in most cases, and shorter operative time.
