RESUMO
OBJECTIVE: To examine whether voided volume (VV) could change the uroflow patterns and result in children with lower urinary tract dysfunction (LUTD). METHODS: Between January 2009 and May 2010, the children with LUTD were enrolled in this study. Uroflowmetry (UF) combined with electromyography (EMG) was performed two times and was reviewed independently by two urologists. UF-EMG curves were classified as bell, staccato, intermittent, plateau, and tower. Patients' expected bladder capacity (EBC) and VV were recorded. Patients were divided into four groups according to their VV and EBC. Group 1, VV <50% of EBC; group 2, VV between 50 and 100% of EBC; group 3, VV between 100 and 125% of EBC; group 4, VV >125% of EBC. RESULTS: A total of 143 patients underwent UF-EMG at least two times and 382 results were obtained. Groups 1, 2, 3 and 4 consisted of 27, 60, 27 and 29 children, respectively. The percentages of normal, intermittent, plateau voiding patterns were 58.5, 12.8, 7.1% in group 1; 79.8, 5.4, 1.8% in group 2; 59.2, 8.5, 2.8% in group 3; and 37.2, 5.1, 2.6% in group 4, respectively. The percentages of staccato and tower pattern were 1.4, 20% in group 1; 9.1, 3.6% in group 2; 30, 0% in group 3; and 55.1, 0% in group 4, respectively. The rate of tower shape curve decreased as voided volume increased, but the rate of staccato curve increased as voided volume increased. CONCLUSIONS: In case of exceeding the EBC, the test should be repeated with normal VV when UF results are being evaluated.

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.

OBJECTIVES: To research the effect of listening to music during shock wave lithotripsy (SWL) on the patient's pain control, anxiety levels, and satisfaction. PATIENTS AND METHODS: The study comprised 400 patients from three hospitals. Half of patients listened to music during their first SWL session but not during their second session. The other half had no music for the first session but the second session was accompanied by music. During all sessions, with and without music, pulse rates, blood pressure, State-Trait Anxiety Inventory-State Anxiety scores (STAI-SA), Visual Analog Scale (VAS scores for pain), willingness to repeat procedure (0 = never to 4 happily), and patient satisfaction rates (0 = poor to 4 = excellent) were assessed. RESULTS: There was no statistical difference between the two groups in terms of blood pressure and pulse rates. In both groups, the STAI-SA and VAS pain scores were lower in the session when music was listened to (p < 0.001). The patients requested more SWL treatment be completed while listening to music and their satisfaction was greater. CONCLUSION: Music lowered the anxiety and pain scores of patients during SWL and provided greater satisfaction with treatment. Completing this procedure while the patient listens to music increases patient compliance greatly and reduces analgesic requirements.

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.

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.
