Malignant mesothelioma of tunica vaginalis: Two extremely rare case reports.

INTRODUCTION: Malignant mesothelioma (MM) of tunica vaginalis is a very rare tumor and it has a poor prognosis. It is not easy to diagnose the disease preoperatively because there is a lack of comprehensive studies and information about the disease. We would like to present our two cases with severe scrotal edema and hydrocele, which were debrided perioperatively due to scrotal necrosis, followed by radical inguinal orchiectomy and subsequently diagnosed as MM of tunica vaginalis. CASE 1: A 74-year-old male patient with bilateral scrotal swelling for 6 months. Right radical inguinal orchiectomy was performed. The pathology result of right radical inguinal orchiectomy material was compatible with malignant mesothelioma of tunica vaginalis. CASE 2: A 90-year-old male patient with complaints of right scrotal swelling for 3 years. A right radical inguinal orchiectomy was performed. The pathology result of right radical inguinal orchiectomy material was compatible with malignant mesothelioma of tunica vaginalis. CONCLUSION AND DISCUSSION: MM has a very poor prognosis therefore early treatment plan should be made. Surgery is the main treatment for malignant mesothelioma of the testis. Although chemotherapy and radiotherapy play an active role in the treatment of metastatic disease, surgery is the first-line therapy in the treatment of the tumor. Also; long-term hydrocele, recurrent epididymitis, scrotal edema can make it harder to detect the tumor diagnosis. MM should be considered in such patients. Necrosis and abscess appearance was not mentioned before in published case reports. In this respect, it should not be ignored the long-term hydrocele situation and the appearance of abscess-epididymitis that cannot be treated properly.

Adherence to guideline recommendations in the management of upper tract urothelial carcinoma: an analysis of the CROES-UTUC registry.

BACKGROUND: The European Association of Urology provides Clinical Practice Guideline on upper tract urothelial carcinoma (UTUC). Due to the rarity of UTUC, guidelines are necessary to help guide decision-making based on the highest quality of care evidence available. OBJECTIVES: To evaluate guideline adherence in the management of UTUC by assessing recommendations on diagnostics needed for risk classification and subsequent treatment selection; to assess predictors for the latter. PARTICIPANTS: Data from the Clinical Research Office of the Endo Urology Society UTUC-registry were included for analysis. STATISTICAL ANALYSIS: Overall compliance were evaluated by cross-tables, differences in risk groups characteristics and treatment selection were assessed by Chi-square tests, predictors for treatment selection by logistic regression analysis. RESULTS: Data from 2380 patients were included. Imaging by CT-scan had highest adherence (85%) but was low for other diagnostics (17.7-49.7%). Multivariable regression analysis showed higher odds of receiving radical nephroureterectomy in patients with large tumours (OR 5.45, 95% CI 3.77-7.87, p < 0.001), signs of invasion (OR 3.07,CI 2.11-4.46, p < 0.001), high tumour grade (OR 2.05, CI 1.38-3.05, p < 0.001) and multifocality (OR 1.76,CI 1.05-2.97, p =0.032). CONCLUSIONS: CT-imaging is the most used and most impactful decision tool for risk-stratification and treatment selection in UTUC. Due to the low compliance in most of the diagnostic recommendations, proper risk stratification is not possible in a significant group of patients raising the question whether current stratification is deemed applicable in daily practice. Established prognostic factors on survival guides decision-making regarding radical versus kidney-sparing surgery. Tumour size was the most influencing factor on treatment decision. CLINICAL TRIAL REGISTRATION: The study was registered at ClinicalTrials.gov (ClinicalTrials.gov NCT02281188; https://clinicaltrials.gov/ct2/show/NCT02281188 ).

Effect of pelvic lymph node dissection and its extent on oncological outcomes in intermediate-risk prostate cancer patients: A multicenter study of the Turkish Uro-oncology Association.

BACKGROUND: Pelvic lymph node dissection (PLND) is the gold standard method for lymph node staging in prostate cancer. We aimed to evaluate the effect of PLND combined with radical prostatectomy (RP) on oncological outcomes in D'Amico intermediate-risk prostate cancer (IRPC) patients. METHODS: Patients with D'Amico IRPC were included in the study. In the overall cohort and subgroups (biopsy International Society of Urological Pathology [ISUP] grade group 2 and 3), patients were divided into two groups as PLND and no-PLND. More extensive PLND, defined as a number of removed nodes (NRN) ≥ 75th percentile. RESULTS: After exclusion, a total of 631 patients were included: 351 (55.6%) had PLND and 280 (44.4%) had no-PLND. The mean age was 63.1 ± 3.60 years. The median NRN was 8.0 (1.0-40.0). The mean follow-up period was 47.7 ± 37.5 months. The lymph node involvement (LNI) rate was 5.7% in the overall cohort, 3.9% in ISUP grade 2, and 10.8% in ISUP grade 3. Patients with PLND were associated with more aggressive clinicopathologic characteristics but no significant difference in biochemical recurrence-free survival (BCRFS) was found between patients with PLND and no-PLND (p = 0.642). In the subgroup analysis for ISUP grades 2 and 3, no significant difference in BCRFS outcomes was found in patients with PLND and No-PLND (p = 0.680 and p = 0.922). Also, PLND extent had no effect on BCRFS (p = 0.569). The multivariable Cox regression model adjusted for preoperative tumor characteristics revealed that prostate specific antigen (PSA) (HR: 1.18, 95% CI: 1.01-1.25; p = 0.048) was an independent predictor of biochemical recurrence (BCR). The optimum cut-off value for PSA, which can predict BCRFS, was assigned to be 7.81 ng/ml, with an AUC of 0.63 (95% CI: 0.571-0.688). The highest sensitivity and specificity were 0.667 and 0.549. CONCLUSION: Overall and cancer-specific survival analyzes were not evaluated because not enough events were observed. Neither PLND nor its extent improved BCRFS outcomes in IRPC. The LNI rate is low in patients with biopsy ISUP grade 2 and the BCR rate is low in those with PSA < 7.81 ng/dl so PLND can be omitted in these IRPC patients.

New behavior therapy in the treatment of acquired premature ejaculation: A comparative study of listening to music. / Nueva terapia conductual en el tratamiento de la eyaculación precoz adquirida: un estudio comparativo de escuchar música.

OBJECTIVES: Premature ejaculation (PE) is one of the most frequently seen causes of sexual dysfunction in males. The aim of this study is to investigate whether the music therapy is effective in the treatment of acquired PE and compare the intravaginal ejaculation latency time (IELT), premature ejaculation diagnostic tool (PEDT), and anxiety scores of patients with acquired PE symptoms that underwent music therapy to patients that were treated with 30 mg dapoxetine. MATERIALS AND METHODS: The study's inclusion criteria was as following: age range from 20-35, married, has regular sexual intercourse, non-smokers, and has no known comorbidities. All participants of the study were with acquired PE based on the International Society for Sexual Medicine criteria. Experimental group (group 1) included 60 patients that were asked to listen to relaxing music and meditate for 45 minutes before the sexual intercourse while continuing their daily routine. This group was selected randomly and prospectively from young healthy individuals. Meanwhile, control group (group 2) included 60 patients who were treated with 30 mg dapoxetine for PE and whose datas were collected from the hospital archive. The patients were evaluated before treatment and re-evaluated (PEDT, IELT, anxiety level) after 60 days. State-Trait Anxiety Inventory was used to assess state and trait anxiety. RESULTS: In both groups, a significant difference (p<0.001) was observed in pre and post-treatment IELT, PEDT, and anxiety scores. Although group 2 showed better improvement in both IELT and PEDT scores, there was no significant difference between two groups. CONCLUSION: Listening to music and other similar anxiety decreasing methods can be a part of treatment plan for PE.

The Effect of Diagnostic Ureterorenoscopy on Intravesical Recurrence in Patients Undergoing Nephroureterectomy for Primary Upper Tract Urinary Carcinoma.

OBJECTIVE: The objective of this study is to evaluate the effect of diagnostic ureterorenoscopy (URS) prior to radical nephroureterectomy (RNU) on intravesical recurrence (IVR), in patients with primary upper urinary tract urothelial carcinoma (UTUC). MATERIALS AND METHODS: Retrospective analysis of 354 patients, who underwent RNU for UTUC from 10 urology centers between 2005 and 2019, was performed. The primary endpoint was the occurrence of IVR after RNU. Patients were divided into URS prior to RNU (Group 1) and no URS prior to RNU (Group 2). Rates of IVR after RNU were compared, and a Cox proportional hazards model was used to evaluate potential predictors of IVR. RESULTS: After exclusion, a total of 194 patients were analyzed: Group 1 n = 95 (49.0%) and Group 2 n = 99 (51.0%). In Group 1, a tumor biopsy and histopathological confirmation during URS were performed in 58 (61.1%). The mean follow-up was 39.17 ± 39.3 (range 12-250) months. In 54 (27.8%) patients, IVR was recorded after RNU, and the median recurrence time within the bladder was 10.0 (3-144) months. IVR rate was 38.9% in Group 1 versus 17.2% in Group 2 (p = 0.001). In Group 1, IVR rate was 43.1% in those undergoing intraoperative biopsy versus 32.4% of patients without biopsy during diagnostic URS (p =0.29). Intravesical recurrence-free survival (IRFS) was longer in Group 2 compared to Group 1 (median IRFS was 111 vs. 60 months in Groups 2 and 1, respectively (p< 0.001)). Univariate analysis revealed that IRFS was significantly associated with URS prior to RNU (HR: 2.9, 95% CI 1.65-5.41; p < 0.001). In multivariate analysis, URS prior to RNU (HR: 3.5, 95% CI 1.74-7.16; p < 0.001) was found to be an independent prognostic factor for IRFS. CONCLUSION: Diagnostic URS was associated with the poor IRFS following RNU for primary UTUC. The decision for a diagnostic URS with or without tumor biopsy should be reserved for cases where this information might influence further treatment decisions.

Vaginocutaneous fistula: A rare long-term complication of transobturator tape procedure for stress urinary incontinence.

INTRODUCTION: Synthetic mid-urethral slings are currently the most common performed surgical procedure for the treatment of female stress urinary incontinence. The transobturator mid-urethral sling technique has been widely accepted owing to its high success and low complication rates. Although complications are rarely seen, it may cause significant morbidity. CASE PRESENTATION: We report a case of vaginocutaneous fistula following transobturator mid-urethral sling procedure and a successful reconstruction with transvaginal sling excision and fistula closure. CONCLUSION: Vaginocutaneous fistula is a known but rarely seen long-term complication of transobturator tape. With an increased use of mesh, various delayed complications can be seen in the long-term follow-up. This case showed us the need for longer and detailed studies that evaluate the effectiveness and safety of the transobturator tape procedure.

Comparison of suture material for vesico-urethral anastomosis in robotic radical prostatectomy.

INTRODUCTION: The aim of this study was to compare outcomes after vesicourethral anastomosis (VUA) with barbed suture (BS) and non-barbed monofilament suture (NBS) in robot-assisted laparoscopic radical prostatectomy (RALRP) in a match - pairs design. MATERIAL AND METHODS: Medical recordings of 385 consecutive patients with prostate carcinoma have been evaluated, and 70 patients who have undergone RALRP-BS were compared with 70 patients with RALRP-NBS in a matched - pairs design. Preoperative clinical parameters (age, prostate-specific antigen, clinical stage, Gleason score of the prostate biopsy, and prostate volume) and operative data (operation, docking, console, posterior reconstruction (PR), anastomosis times, duration of catheter, length of hospital stay, estimated blood loss, time to perform the anastomosis and its quality) were evaluated, as well as postoperative parameters (pathological stage, Gleason score, specimen weight, follow-up duration, biochemical recurrence, complication rates, and duration of postoperative analgesic treatment). RESULTS: No statistically significant difference was found for pre-operative parameters between the two groups. Although, anastomosis time, quality of anastomosis, duration of urethral catheter and total anesthesia time were significantly less in the RALRP-BS group than in the RALRP-NBS group (P <0.01). Other peri- and postoperative parameters were not statistically significant between the two groups. Pathological data and the follow-up period and complication rates were similar between the two groups. CONCLUSIONS: This study showed that, RALRP-BS is a safe, efficient and cost-effective PR and VUA during RALRP than compared with RALRP-NBS. Shorter anastomosis time, operative time and posterior reconstruction time, while it may be equivalent with regard to estimated blood loss (EBL), catheterization time and early continence rates at 4-6 weeks.

Visual clarity of irrigants used during flexible ureterorenoscopy: an in vitro comparison.

INTRODUCTION: Saline solution is the standard irrigant used during ureteroscopy. However, there is an opinion that water has better visual clarity. We aimed to compare the visual clarities of saline, water, and 5% mannitol as an irrigant during ureteroscopy. MATERIAL AND METHODS: An in vitro model consisting of an irrigant-filled container and a fiberoptic flexible ureteroscope was designed. A 1951 USAF Resolution Test Target and color checker within irrigants were used to evaluate the clarity of vision. The visual clarity was compared for 0.9% saline, distilled water and 5% mannitol solution with screen resolution and color contrast. The tests were repeated after adding human blood (2/400 ml) and contrast (20/400 ml) to the irrigants. RESULTS: There was no significant difference in resolution values of three plain irrigants at a distance of 10 mm. However, when blood was added to the irrigants, a better resolution of 29.3% for water and 20.6% for mannitol was achieved compared to saline. At 20 mm of distance, it was observed that the difference was more pronounced in irrigants with blood. Water and mannitol had 55.6% and 37.1% better resolution than saline, respectively. In the color reproduction test, there was no significant difference in the three plain irrigants, however, water had better color contrast compared to the others. CONCLUSIONS: Water and 5% mannitol did not provide a significant image clarity advantage compared to saline. However, when blood was added to the irrigants, water provided significantly better visual clarity compared to saline. The use of water during various clinical scenarios in flexible ureteroscopy should be further investigated.

The evaluation of the effectiveness of Gilaburu (Viburnum opulus L.) extract in the medical expulsive treatment of distal ureteral stones.

OBJECTIVE: Medical expulsive therapy is an important non-invasive treatment modality that facilitates the passage of ureteral stones. The aim of the present study was to evaluate the efficacy of Gilaburu (Viburnum opulus) extract in the treatment of distal ureteral stones <10 mm. MATERIAL AND METHODS: Data of 103 patients were retrospectively analyzed. Patients were divided into two groups: those given V. opulus 1000 mg peroral 3×2 and diclofenac 50 mg peroral on-demand (n=53) and those given only diclofenac sodium 50 mg peroral on-demand (n=50). Comparisons of stone expulsion rates and the elapsed time until the expulsion between the groups were determined as primary outcome measures. The comparison of the need for additional treatment [ureteroscopy (URS) or extracorporeal shock wave lithotripsy (ESWL)], the need for emergency admission, analgesic requirement, and the complication rates in additional treatment were determined as secondary outcome measures. RESULTS: The mean age of the patients was 45.8±14.5 years. The rate of stone expulsion was significantly higher (82% vs. 66%, p=0.026), and elapsed time to stone expulsion was significantly shorter (9±1.8 vs. 14±2.3 day, p=0.018) in the V. opulus group. The need for additional treatment (URS and ESWL) and analgesic requirement was less in the V. opulus group (9.4% vs. 20%, p=0.038 and 24.5% vs. 44%, p=0.042, respectively). CONCLUSION: V. opulus is an herbal treatment alternative that facilitates the passage of ureteral stones <10 mm. Prospective, randomized studies are needed to support these results.

Smartphone-based stent tracking application for prevention of forgotten ureteral double-J stents: a prospective study

ABSTRACT Purpose: Retained or forgotten ureteral stents (FUS) have a potential to cause significant morbidity as well as medico-legal issues and increased cost. We aimed to evaluate the efficacy and usefulness of smartphone-based Ureteral Stent Tracker (UST) application and compare the results with basic appointment card system to prevent FUS, prospectively. Materials and Methods: A total of 90 patients who underwent ureteroscopic stone treatment procedure with indwelling DJ stents were equally distributed into two groups. In group-1, patients were followed using UST application. In group-2, only appointment cards were given to the patients. Two groups were compared in terms of stent overdue times and complete lost to follow up rates. Results: Forty-four patients in group-1 and 43 patients in group-2 completed the study. Among patients, 22.7% in group-1 and 27.9% in group-2 did not return for the stent removal on the scheduled day. In group-1, these patients were identified using the UST and called for the stent removal on the same day. After 6 weeks of maximal waiting period, mean overdue times in group-1 and group-2 were 3.5 days and 20 days, respectively (p = 0.001). In group-2, 3 patients (6.9%) were lost to follow up, while in group-1, it was none (p = 0.001). Conclusions: We found that the patients who were followed by the smartphone-based UST application has less overdue times and lost to follow up cases compared to the basic appointment card system. The UST application easily follows patients with indwelling ureteral stents and can identify patients when overdue.

Endoscopic, Single-Session Management of Encrusted, Forgotten Ureteral Stents.

Background and Objectives: Remained or forgotten ureteral double-J stents may cause serious complications. Removing of an encrusted, forgotten stent can be challenging. We present our experience with heavily encrusted ureteral stents and discuss the endourologic treatment options as well as their effectivity. Materials and Methods: Eleven men and six women (mean 48.58 ± 14.48 years of age) with 18 encrusted forgotten stents (mean 16.4 ± 13.25 months of indwelling) were treated at our clinic. All patients underwent the operation after negative urine cultures were obtained. Their medical records were retrospectively reviewed and analyzed in terms of number of interventions required to remove the stent, operation time, complications, hospital stay and stone-free rate. Results: According to the Forgotten-Encrusted-Calcified (FECal) classification, the most common form of stent encrustation was grade III (64.7%) and 17.6% of the stents were fragmented. Four of 17 patients were initially treated with extracorporeal shock-wave lithotripsy. The patients required a mean of two endoscopic interventions for removing the encrusted stent and all stents were removed endoscopically in a single session. The mean operating time was 63.3 ± 41.8 minutes. Cystolithotripsy followed by ureteroscopy was the most common intervention (41.1%). Of the 17 patients, peroperative and postoperative complications were Clavien grade I in two, grade II in two and grade IIIb in one. The mean hospital stay was 1.3 ± 0.99 days. All patients were stone-free after a month of stent removal. Conclusions: The endourological removal of the encrusted forgotten stents in a single session is feasible and effective with a minimal morbidity. The treatment strategy should be to minimize the number of interventions.

Protective Effect of All-Trans Retinoic Acid in Cisplatin-Induced Testicular Damage in Rats.

PURPOSE: To investigate the effects of all-trans retinoic acid (ATRA) in cisplatin (CP)-induced testicular damage in rats. MATERIALS AND METHODS: Twenty-eight male Wistar rats were divided into four groups: Control, ATRA alone, ATRA+CP, and CP alone. Body weight, testicular weight, sperm count, sperm motility, percentage of abnormal sperm, total antioxidant status (TAS), total oxidant status (TOS), oxidative stress index (OSI) in testicular tissue, and testicular histopathology were compared among groups. RESULTS: The sperm count and motility significantly decreased and the percentage of abnormal sperm significantly increased in the CP group compared to the control and ATRA groups. CP+ATRA administration significantly increased the sperm count and motility, but reduced the abnormal sperm count. CP administration significantly increased TOS and OSI compared to the control group and the other groups. Administering CP+ATRA significantly decreased TOS and the OSI in testicular tissue and reduced spermatogenesis, but increased the Johnsen score. CONCLUSIONS: The destructive effects of CP treatment on testicular tissue and spermatogenesis were reduced by administering ATRA.

The efficacy and safety of bilateral same-session ureteroscopy with holmium laser lithotripsy in the treatment of bilateral ureteral stones.

BACKGROUND: A staged ureteroscopic procedure is the generally preferred method in the treatment of bilateral ureteral stones due to the risk of bilateral injury. In this study we aimed to evaluate the safety and efficacy of bilateral same-session ureteroscopy (BS-URS) in terms of complications, operation time, serum creatinine, hospital stay and stone-free rates. METHODS: A total of 75 patients who underwent BS-URS and holmium laser lithotripsy were evaluated, retrospectively. The patients were re-evaluated postoperatively after four weeks with ultrasonography, X-ray or computed tomography. Pre- and postoperative variables were analyzed. The results of BS-URS were also compared with unilateral URS cases performed in the same time period. RESULTS: BS-URS was performed in 58 men and 16 women with a mean age of 46.3 years. The mean operating time was 69 min. In patients with stone burden ≥20 mm, the mean operative time was longer. Intraoperative complications were observed in eight patients, Clavien grade I in seven, and Clavien grade IIIb in one. Early postoperative complications included fever and hematuria were seen in 10.6% of the patients. One patient underwent secondary URS for residual stone. Stone free rate after four weeks was 98.6%. Overall complication and and stone-free rates were similar in BS-URS and unilateral URS groups (P>0.05). The mean operating time was significantly longer in BS-URS patients (P=0.001). CONCLUSIONS: BS-URS is as safe and efficient procedure as unilateral ureteroscopy with high stone-free and minimal morbidity rates in the treatment of bilateral ureteral stones in appropriate patients.

Among patients, 22.7% in group-1 and 27.9% in group-2 did not return for the stent removal on the scheduled day. In group-1, these patients were identified using the UST and called for the stent removal on the same day. After 6 weeks of maximal waiting period, mean overdue times in group-1 and group-2 were 3.5 days and 20 days, respectively (p = 0.001) . In group-2, 3 patients (6.9%) were lost to follow up, while in group-1, it was none (p = 0.001). CONCLUSIONS: We found that the patients who were followed by the smartphone-based UST application has less overdue times and lost to follow up cases compared to the basic appointment card system. The UST application easily follows patients with indwelling ureteral stents and can identify patients when overdue.

All-trans retinoic acid prevents cisplatin-induced nephrotoxicity in rats.

The aim of this study is to investigate the effects of all-trans retinoic acid (ATRA) use on cisplatin (CP)-induced nephrotoxicty. Twenty-eight rats were randomly divided into four groups. The rats in the control group were injected a single dose of 1 ml/kg saline intra-peritoneally (IP) during 10 days. The rats in the ATRA group were injected a single dose of ATRA during 10 days. The rats in the ATRA+CP group were injected a single dose of CP on the fourth day of the 10 days of ATRA treatment. The rats in the CP group were injected a single dose of CP on the fourth day of 10 days without administering a treatment. After treatment, the groups were compared with regard to total antioxidant status (TAS), total oxidant status (TOS), and oxidative stress index (OSI) levels in renal tissue and renal histopathology. The serum creatinine and urea values were statistically significantly higher in the CP group compared to the other groups. The serum creatinine and urea values were statistically significantly lower in the ATRA+CP group when compared to the CP group. Although the TOS and OSI levels were found to be lower in the ATRA+CP group compared to the CP group, the difference was not statistically significant. Administration of ATRA together with CP was observed to reduce the histopathologic destruction in the kidney and lead to mild tubular degeneration, vacuolization, and necrosis (57.1% grade 1; 28.6% grade2, and 14.3% grade 3 necrosis). The results of the present study have revealed that ATRA administration ameliorates CP-induced nephrotoxicity; however, further studies are required to identify this issue before clinical application.

The sufficiency of 6 core sextant prostate biopsy in patients with prostate specific antigen (PSA) values over 20 ng/mL.

OBJECTIVE: In this study, we aimed to investigate sufficiency of 6 core prostate biopsy in patients with PSA levels elevated above 20 ng/mL. MATERIALS AND METHODS: The medical record of the patients who received prostate biopsy at our institution between August 2011 to August 2016 who had serum total PSA values above 20 ng/mL, were reviewed retrospectively. In this study, we included 40 patients who received 6 core prostate biopsy and 40 patients who received 12 core prostate biopsy. A total number of 80 patients were enrolled in this study. Patients were divided into two groups, a 6 core biopsy group and a 12 core biopsy group. These groups are compared according to age, total PSA, prostate volume and final pathological diagnosis. RESULTS: Based on final pathological diagnosis, 2 patients (5%) had benign pathology and 38 patients (95%) had PCa in both group 1 and 2. The cancer detection rate in both groups was 95%. Although there were higher values of mean age, mean total PSA, and mean prostate volume in group 1, there was no statistically significantly difference at this variables in both groups. CONCLUSION: Although taking 6 core biopsies is not recently recommended, we proved that 6 core biopsy is adequate for patients with PSA values above 20 ng/mL.

The Rare Togetherness of Bladder Leiomyoma and Neurofibromatosis.

Neurofibromatosis Type 1 (Von Recklinghausen disease) is a common, autosomal dominant hereditary disorder characterized by involvement of multiple tissues derived from the neural crest. Urinary system involvement in neurofibromatosis is a rare condition. Leiomyoma of the bladder is a rare benign mesenchymal tumor. In this case, our experience and approach regarding the bladder leiomyoma development in a patient diagnosed with neurofibromatosis are presented and the literature data has been reviewed.

Listening to music during shock wave lithotripsy decreases anxiety, pain, and dissatisfaction : A randomized controlled study.

BACKGROUND: We analyzed the effects of music on pain, anxiety, and overall satisfaction in patients undergoing a shock wave lithotripsy (SWL) procedure. METHODS: A total of 200 patients scheduled to undergo SWL were included in this study. Group 1 consisted of 95 patients who listened to music during the SWL session while group 2 included 105 patients who did not listen music during the procedure. State-Trait Anxiety Inventory (STAI) was used to assess state and trait anxiety (STAI-S/T). A visual analog scale (VAS) was used at the end of the session in order to assess pain, willingness to repeat the procedure, and overall patient satisfaction. Hemodynamic parameters including systolic blood pressure (SBP), diastolic blood pressure (DBP), and heart rate (HR) were recorded before and after the session. RESULTS: No statistically significant difference was found between the two groups in terms of stone characteristics, SWL parameters, pre-SWL STAI-T/S scores, and pre-SWL hemodynamic parameters. Post-SWL STAI-S scores were found to be lower in patients who listened to music (p = 0.006). At the end of the SWL, VAS scores of pain, satisfaction, and willingness to repeat procedure were significantly different in favor of the music group (p = 0.007, p = 0.001, p = 0.015, respectively). SBP, DBP, and HR were significantly higher in patients who did not listen to music (p = 0.002, p = 0.024, p = 0.001, respectively). CONCLUSION: Music can be an ideal adjunctive treatment modality for patients undergoing SWL treatment. It has the potential to enhance patient compliance and treatment satisfaction by reducing the procedure-related anxiety and pain perception.

Comparison of intraperitoneal and intratesticular ozone therapy for the treatment of testicular ischemia-reperfusion injury in rats.

We compare the efficacy of intratesticular ozone therapy with intraperitoneal ozone therapy in an experimental rat model. For this purpose, 24 rats were divided into four groups including sham-operated, torsion/detorsion, torsion/detorsion plus intraperitoneal ozone (O-IP), and torsion/detorsion plus intratesticular ozone (O-IT). The O-IP ozone group received a 4 mg kg-1 intraperitoneal injection of ozone, and the O-IT group received the same injection epididymally. At 4 h after detorsion, the rats were sacrificed and orchiectomy materials were assessed histopathologically. Spermatogenesis in the seminiferous tubules and damage to the Sertoli cells were histopathologically evaluated in the testes using the Johnsen scoring system. i-NOS and e-NOS activities in the testis tissue were also evaluated. Torsion-detorsion caused a decreased Johnsen score and increased apoptosis of spermatogonial and Sertoli cells. Ozone injection prevented increases in Johnsen score and i-NOS level. e-NOS level of the O-IP group was significantly lower than that of the O-IP group, and i-NOS level of the O-IT group was significantly lower than that of the O-IP group. Local ozone therapy is more effective than systemic ozone therapy at improving IRI-related testicular torsion. Our study is the first to show that the efficacy of intratesticular implementation of ozone therapy is higher than that of intraperitoneal ozone therapy.
