The effect of music therapy during shockwave lithotripsy on patient relaxation, anxiety, and pain perception.

Abstract 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.

Fournier's gangrene current approaches †

Fourniers gangrene is a rare but highly mortal infectious disease characterised by fulminant necrotising fasciitis involving the genital and perineal regions. The objective of this study is to analyse the demographics, clinical feature and treatment approaches as well as outcomes of Fourniers gangrene. Data were collected retrospectively from medical records and operative notes. Patient data were analysed by demographics, aetiological factors, clinical features, treatment approaches and outcomes. Twelve patients (five female and seven male) were enrolled in this study. The most common aetiology was perianal abscess (41·6%). Wound cultures showed a mixture of microorganisms in six (50%) patients. For faecal diversion, while colostomy was performed in six cases (50%), Flexi‐Seal was used in two cases (16·6%). In four patients (33·4%), no faecal diversion was performed. Negative pressure wound therapy (NPWT) system was effective in the last four patients (33·4%). The mean hospitalisation period in patients who used NPWT was 18 days, while it was 20 days in the others. NPWT in Fourniers gangrene is a safe dressing method. It promotes granulation formation. Flexi‐Seal faecal management is an alternative method to colostomy and provides protection from its associated complications. The combination of two devices (Flexi‐Seal and NPWT) is an effective and comfortable method in the management of Fourniers gangrene in appropriate patients.

Retrograde intrarenal surgery in pediatric patients.

Urinary tract stone disease is seen at a level of 1%-2% in childhood (< 18 years). In recent years, however, there has been a marked increased in pediatric stone disease, particularly in adolescence. A carbohydrate- and salt-heavy diet and a more sedentary lifestyle are implicated in this increase. Although stone disease is rare in childhood, its presence is frequently associated with metabolic or anatomical disorders or infectious conditions, for which reason there is a high possibility of post-therapeutic recurrence. Factors such as a high possibility of recurrence and increasing incidence further enhance the importance of minimally invasive therapeutic options in children, with their expectations of a long life. In children in whom active stone removal is decided on, the way to achieve the highest level of success with the least morbidity is to select the most appropriate treatment modality. Thanks to todays advanced technology, renal stones that were once treated only by surgery can now be treated with minimally invasive techniques, from invasion of the urinary system in an antegrade (percutaneous nephrolithotomy) or retrograde (retrograde intrarenal surgery) manner or shock wave lithotripsy to laparoscopic stone surgery. This compilation study examined studies involving the RIRS procedure, the latest minimally invasive technique, in children and compared the results of those studies with those from other techniques.

Protective effect of syringic acid on kidney ischemia-reperfusion injury

Abstract The objective of the present study was to determine whether preischemic administration of syringic acid (SA) would attenuate renal ischemia-reperfusion injury (IRI). Rats were divided into three groups: Sham group; IR group; and IR + SA group. The effects of SA were examined using biochemical parameters including serum ischemia-modified albumin (IMA), total antioxidant status (TAS), total oxidant status (TOS), oxidative stress index (OSI), tissue superoxide dismutase (SOD), glutathione peroxidase (GPx), catalase (CAT) and malondialdehyde (MDA). The apoptosis status and histopathological changes were evaluated. After calculating the score for each histopathological change, the total score was obtained by summing all the scores. In the SA group, MDA, IMA, TOS, and OSI decreased significantly compared to the IR group. After SA administration, the increase in GPx activity was found to be significant. Apoptosis decreased significantly in the SA group compared with the IR group. The total score significantly decreased after administration of SA. Taken together, our findings suggest that SA preconditioning is effective in reducing tissue damage induced in kidney IRI. Renal histology also showed convincing evidence regarding the protective nature of SA.

Predictive role of hematologic parameters in testicular torsion

Purpose To evaluate the predictive role of the neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), mean platelet volume (MPV), and platelet count (PLT) in the diagnosis of testicular torsion (TT) and testicular viability following TT. Materials and Methods We analyzed two study groups in this retrospective study: 75 patients with a diagnosis of TT (group 1) and 56 age-matched healthy subjects (group 2). We performed a complete blood count as a part of the diagnostic procedure, and NLR, PLR, MPV, and PLT values were recorded. We compared the patient and control groups in terms of these parameters. Then, TT patients were divided into two subgroups according to the time elapsed since the onset of symptoms. Subsequently, we evaluated the relationship between the duration of symptoms and these parameters. Results There were significant differences between groups 1 and 2 in NLR, PLR, and PLT (p<0.001 for all). There was no predictive role of MPV in the diagnosis of TT (p=0.328). We determined significantly high sensitivity and specificity levels for NLR in the prediction of TT diagnosis (84% and 92%, respectively). Furthermore, NLR was significantly related to the duration of symptoms in TT patients (p=0.01). Conclusions NLR may be a useful parameter in the diagnosis of TT. Furthermore, NLR may be used as a predictive factor for testicular viability following TT.

Do Hypertension, diabetes mellitus and obesity increase the risk of severity of nephrolithiasis?

Objective: In this study we planned to investigate the relationship between presence of kidney stones and stone burden with hypertension (HT), diabetes mellitus (DM) and body mass index (BMI). Methods: A total of 574 patients were included in the study. None of the patients had a history of stones. The 121 patients with kidney stone identified on ultrasound evaluation and the 453 patients with no stones were compared in terms of HT, BMI and DM. The stone burden of 121 patients with diagnosed stones was compared in terms of the same variables. Results: Of the 121 patients with kidney stones 30 (24.7%) had HT, while 66 (14.5%) of the 453 patients without stones had HT (p=0.007). BMI values of those with and without stones were 27.2 ± 4.93 kg/m2 and 25.29 ± 4.12 kg/m2, respectively (p<0.001). Twenty-five (20.6%) of the patients with stones diagnosed by ultrasound had DM, while 49 (10.8%) of those without stones had DM (p=0.004). When comparing patients with and without kidney stones, logistic regression analysis revealed that DM (odds ratio [OR] 2.06, 95% confidence interval [CI] 1.17 to 3.63, p=0.013) and BMI (OR 1.08, CI 1.03 to 1.13, p=0.003) were independently associated with presence of stones. No significant relationship was found between the same variables and cumulative stone diameter (CSD) and stone surface area (SA) evaluated for stone burden. Conclusions: While diabetes mellitus, Hypertension and increased Body Mass Index may add to the possibility of stone formation, they did not affect stone burden.

Left ventricle ejection fraction may predict mortality in renal transplant patients

Abstract Purpose: Mortality is a major problem in renal transplant patients, and appropriate preoperative evaluation is very important. We retrospectively reviewed the left ventricle ejection fraction (LVEF) of renal transplant patients. Material and methods: The clinical records of 1763 patients who had preoperative LVEF results and who underwent renal transplantation at Akdeniz University Faculty of Medicine during the years 2004–2014 were studied. The LVEF limit was set at 55%. LVEF, age, gender, diabetes mellitus, hypertension, type of dialysis were assessed by linear multiple regression analysis on survival. Results: There were a total of 1763 renal transplant patients. Those with LVEF of <55% were identified as having left ventricular dysfunction. The mean LVEF was 59.4 ± 9.1 in the 43 patients who died after renal transplantation, while it was 62.6 ± 7.4 in the survivors (p = 0.02). The mortality rate in the LVEF < 55% group was 6.8% (11/162 patients), while mortality in the LVEF ≥ 55% group was 2% (32/1601 patients, p < 0.001). LVEF was found to be the most powerful variable on survival by the linear multiple regression analysis, R2 = 0.05, p < 0.001. Conclusion: LVEF may predict mortality in renal transplant patients. LVEF is known to be lower in patients with high cardiac mortality, who may require greater modifications of the postoperative risks.

The association of urolithiasis and androgenetic alopecia

Abstract Objectives: The objective of this study is to investigate whether patients with androgenetic alopecia were at risk in terms of urinary system stone disease. Patients and methods: Patients with no baldness (Hamilton–Norwood Scala [HNS] stage I) were categorized as Group I, those with hair loss in the frontal region (HNS stages II, III, IIIa, and IVa) as Group II, those with hair loss in the vertex region (HNS stage III-vertex, V) as Group III and those with hair loss in both vertex and frontal regions (HNS stages IV, Va, VI, and VII) as Group IV. Patients in all groups were compared in terms of presence of stone, and the presence of any association between alopecia and urolithiasis, with common etiological risk factors, was investigated. Results: Three hundred and two male patients were included in the study. The presence of urolithiasis was detected in 28.9% of patients in Group I; 26.5% of Group II; 36.9% of Group III; and 44.4% of Group IV (p = 0.085). Among patients aged under 60, urinary stone disease was detected in 30.8% of patients in Group I; 26.4% of Group II; 41.2% of Group III; and 53.8% of Group IV (p = 0.001). In patients aged over 60, urolithiasis was detected in 12.5% of patients in Group I; 26.9% of Group II; 32.2% of Group III; and 37.8% of Group IV (p = 0.371). Conclusions: We determined a significant correlation between vertex pattern and total alopecia with urolithiasis in patients younger than 60 years old.

The relationship between platelet–lymphocyte ratio and severity of erectile dysfunction

The prognostic importance of platelet–lymphocyte ratio (PLR) is already known for various artery diseases. In this study, the relationship between PLR and severity of erectile dysfunction (ED) is examined in patients with impotence. The data from patients suffering from erection problems was screened retrospectively. Detailed medical history, age, International Index of Erectile Function‐5 (IIEF‐5) scores, fasting blood glucose, lipid, whole blood count, and hormone profile values were examined. Patients with no ED were selected as the control group. All men answered the IIEF‐5 questions and were then classified according to their scores. Patients were determined to have severe ED (scores 5–7), moderate ED (scores 8–16), or mild ED (scores 17–21). An IIEF‐5 score greater than 21 was accepted for the control group. The PLR values from both patient and control groups were evaluated. Demographic data were similar in both groups. Mean PLR value was 104 in control and 118 in the patient group (p < 0.001). PLR value increased depending on the severity of ED. Mean PLR values were 108 in mild, 116 in moderate, and 130 in severe ED groups. Compared with the control group, this value was statistically significant for patients with moderate and severe ED (p = 0.04 and p < 0.001). PLR showed weak negative but significant correlation with IIEF‐5 scores (r = −0.27 and p < 0.001). The PLR value was found to be higher in patients with ED. PLR value may be related to ED and its severity in patients with impotence.

Time to say good bye to shockwave lithotripsy

We read with great interest the recent article by Kruck et al. [1] on the comparative study of minimally invasive percutaneous nephrolithotomy (MIP), retrograde intrarenal surgery (RIRS) and shock wave lithotripsy (SWL) in renal stone treatment. In this article, authors compared clinical outcome, complications, stone-free rate (SFR) and stonefree survival with regard to stone size and localization. They concluded the significant advantages of the MIP and RIRS procedures for increased SFRs, lower risk of stone persistence and prolonged stone-free survival compared with SWL. We congratulate the authors for their work and thank them for bringing this debatable topic to our attention; however, we feel that some issues described in their paper need further discussion. Over the last decade, with the miniaturization of instruments in percutaneous nephrolithotomy and technological improvements in flexible ureteroscopes, working instruments and laser technology, RIRS, MIP and microperc techniques have become more attractive procedures for the treatment of nonbulky renal urolithiasis [2, 3]. Furthermore, in the recent years, there has been an increasing realization that the SWL has unpredictable and unfavorable results when comparing with other minimally invasive methods [4–6]. On a comparative study of RIRS and SWL, El-Nahas et al. [4] concluded the significant advantages of the RIRS procedure for higher stone-free rate and lower retreatment rate for the management of medium sized lower pole renal stones. Another three comparative studies, evaluating the outcomes of PNL and SWL, showed that the success rate was statistically higher, and retreatment or auxiliary procedures were less for PNL compared with SWL [5–7]. But in all these studies, PNL or RIRS was associated with an increased risk of complications compared with SWL. Similar results were reported in the present study by Kruck et al. [1]. Despite publishing these studies and clinical treatment guidelines, there are no universally accepted paradigms to treat renal stones, due to absence of robustly designed randomized controlled trials [8, 9]. Until the publishing of welldesigned randomized prospective large series examining the efficacy and safety of minimally invasive treatments, SWL will be the most valuable treatment option because of its noninvasive nature, low morbidity rate and high patient acceptance [3]. Therefore, current EAU guidelines recommend SWL remains the method of first choice for stones \2 cm within the renal pelvis, upper or middle calices and for stones\1.5 cm within lower pole calices [9].
