A Modified Left Ileal Conduit in the Presence of a Left Short Ureter Following an Urgent Radical Cystectomy: A Case Report.

The ileal conduit is the most common method performed for urinary diversion following radical cystectomy. The prepared conduit is usually placed on the right abdominal wall. There is not enough experience and literature on left-sided ileal conduits. Here, we report a case of a left-sided ileal conduit with a modified method and describe the surgical technique. A 68-year-old male patient had undergone an urgent radical cystectomy operation one year ago due to bladder cancer and gross hematuria. However, urinary diversion was not performed, and a bilateral nephrostomy was inserted. An ileal conduit was planned for the patient after oncological stabilization. On preoperative evaluations, bilateral ureters were observed to be short, with the left being prominent. The prepared ileal conduit was passed under the sigmoid mesentery due to the short ureters and placed on the left abdominal wall. There were no major complications during follow-ups. We emphasize that the method we performed is a safe option in mandatory situations.

Asymptomatic Giant Right Renal Oncocytoma: A Case Report.

Renal oncocytoma is usually detected incidentally. It can be considered as a renal cell carcinoma (RCC) on preoperative imaging. They usually present as small masses and usually look like benign tumors. Giant oncocytomas are rare. A 72-year-old male patient was seen in the outpatient department for left scrotal swelling. Ultrasound (US) showed a giant mass compatible with RCC in the right kidney which was incidentally detected. Abdominal computed tomography (CT) revealed a mass with an axial diameter of 167×146 mm, compatible with RCC, a heterogeneous mass of soft tissue density with central necrosis. There was no evidence of tumor thrombus in the right renal vein or inferior vena cava. Open radical nephrectomy was performed through an anterior subcostal incision. Pathological examination revealed a 17×15 cm renal oncocytoma. The patient was discharged on the sixth day postoperatively. Clinically or radiologically, renal oncocytoma and renal cell carcinoma usually cannot be distinguished, although oncocytoma may be suspected if a central scar with fibrous extensions is seen, the so-called "spoke-wheel appearance". The treatment decision should be made according to the clinical aspects. Radical/partial nephrectomy or thermal ablation can be considered as treatment options. In this article, we review the literature on the radiological and pathological features of renal oncocytoma.

Predictive value of ureteral wall thickness (UWT) assessment on the success of internal ureteral stent insertion in cases with obstructing ureteral calculi.

To evaluate the possible role of ureteral wall thickness (UWT) assessment in the prediction of the success for stent placement in cases with obstructing ureteric stones. 227 adult patients with a single unilateral obstructing ureteral stone requiring internal ureteral stent placement were included. In addition to stone size, the ureteric wall thickness at the impacted stone site and the degree of hydronephrosis were also assigned on CT images. Patients were divided into two subgroups: Group 1: patients in whom internal ureteral stent could not be passed beyond the stone and Group 2: patients in whom an internal ureteral stent was passed successfully. The possible relationship between the UWT values and the success of stent placement, degree of hydronephrosis were comparatively evaluated. The majority of the stones were located in the proximal ureter in Group 1 and the degree of hydronephrosis was also higher in these cases. Moreover, while the mean value of UWT calculated on CT images was 4.3 ± 0.9 mm in Group 1, this value was noted to be 2.5 ± 0.8 mm in cases of group 2. A cutoff UWT value of 3.35 mm was highly predictive for the stent insertion and cases with higher values required additional procedures or percutaneous nephrostomy tube placement. UWT value calculated at the obstructing stone site was found to be predictive enough for the likelihood of internal ureteral stent passage with high sensitivity and specificity. This evaluation may enable the urologist to make the best decision for urinary diversion in such cases.

Contrary effects of coenzyme Q10 and vitamin E after testicular ischemia/reperfusion in a rat model validated with glucose metabolism imaging.

OBJECTIVE: To evaluate the efficacy of antioxidants in cellular-level post-ischemia/reperfusion injury of the testis and to validate these effects with 18F-fluorodeoxyglucose positron emission tomography. METHODS: Fifty-six adult male rats were randomly divided into seven groups-Group 1: sham; Group 2: ischemia/reperfusion only group; Group 3: ischemia was induced and vitamin E (100 mg/kg) was administered intraperitoneally 30 min before reperfusion; Group 4: vitamin E was given intraperitoneally without ischemia/reperfusion; Group 5: ischemia was induced and coenzyme Q10 (10 mg/body weight) was administered intraperitoneally 30 min before reperfusion; Group 6: coenzyme Q10 was administered intraperitoneally without ischemia/reperfusion; Group 7: ischemia was induced and coenzyme Q10 + vitamin E was administered intraperitoneally 30 min before reperfusion. After detorsion, fluorodeoxyglucose was applied to all groups according to the animals' weight and fluorodeoxyglucose positron emission tomography was performed after 1 h. In pursuit of imaging, orchiectomy was performed for histopathological and biochemical evaluations. RESULTS: A significant effect of group on catalase, maximum standardized uptake value, and seminiferous tubule diameters (p < 0.005) was observed. According to this, combining ischemia/reperfusion with vitamin E increased the maximum standardized uptake value significantly higher than in all other groups; in addition, catalase was significantly higher than in Groups 4-6. Histopathological outcomes revealed that "sham" had significantly larger seminiferous tubule diameter than Groups 2-4. Also, "ischemia/reperfusion" was the only group which had significantly smaller seminiferous tubule diameters than Groups 6 and 7. CONCLUSION: In contrast to vitamin E, coenzyme Q10 provided remarkable regression of oxidative stress-induced enzymes and revealed consistent effects on histopathological outcomes, which were validated with fluorodeoxyglucose positron emission tomography imaging.

Hypergonadotropic Hypogonadism: Management of Infertility.

BACKGROUND: Medical treatments are used either alone or in combination with assisted reproductive techniques for the treatment of infertile patients with hypergonadotropic hypogonadism. A wide range of treatment options such as gonadotropins, aromatase inhibitors (AIs), selective estrogen receptor modulators (SERMs) and their combination are available as options. OBJECTIVE: The aim of this review was to evaluate treatment options for infertile men with hypergonadotropic hypogonadism. METHODS: A literature search of MEDLINE (1980-2019) was conducted using the terms 'hypogonadism', 'male infertility', 'gonadotropins', 'SERMs' and 'AIs'. Pathologies leading to hypergonadotropic hypogonadism and treatment modalities such as gonadotropins, SERMs, AIs and surgical treatment were discussed. RESULTS: FSH increases spontaneous pregnancy rates but the level of evidence was proven to be low for live birth rates. AIs are valid treatment options for patients with low T/E2 ratio as they significantly increase sperm concentrations. SERMs are recommended for infertile males with a sperm concentration between 10-20 million. Varicocele was reported to increase testosterone levels of hypogonadic infertile males. CONCLUSION: Medical treatment modalities such as gonadotropins, SERMs, AIs and a combination of these therapies has been showed to have some effect in improvement of fertility but is not mainstream of the treatment.

A Population-Based Study of Peyronie's Disease in Turkey: Prevalence and Related Comorbidities.

INTRODUCTION: Peyronie's disease (PD) prevalence varies between 0.39% and 20% and studies on PD prevalence are limited. AIM: This study aims to determine the prevalence of PD in males aged ≥30 years in Turkey and to evaluate etiological factors associated with it. METHODS: The study was conducted in 12 regions of Turkey according to the Eurostat Nomenclature of Territorial Units for Statistics 1 classification and included 1,208 patients. Survey questionnaires including questions about demographic features and basic health status as well as about diagnosis and etiology of PD were put forth to the volunteers who agreed to participate in the study. Diagnosis of probable PD was established by evaluating the questionnaires. Patients with a diagnosis of congenital penile curvature were excluded from the group with PD. Chi-square test, Fisher's exact test, and Mann-Whitney U test were used. MAIN OUTCOME MEASURE: The primary outcome analyzed in this article was the prevalence rate of PD in Turkey and the associated comorbidities. RESULTS: The prevalence of PD was determined as 5.3%. The rates of participants with PD were found to be the highest in the 50-59 years group (27%) and in the North-East Region (20%). Compared with participants without PD, participants with PD were older (median: 52 interquartile range [41-64] vs 45 [37-55]; P < .001) and the rates of smokers (73% vs 60.9%; P = .036) and those having diabetes mellitus (17.5% vs 9.2%; P = .045), hypertension (14.3% vs 6.9%; P = .041), and heart failure were higher (7.9% vs 2.5%; P = .027). Male with PD symptoms preferred their partners on top during sexual intercourse (15.2% vs 34.1%; P < .001). This is the first study to evaluate premature ejaculation prevalence and related comorbidities with face-to-face interviews. CONCLUSION: The prevalence of PD was 5.3% in Turkey. Besides advanced age, smoking, position of sexual intercourse, and presence of comorbidities especially diabetes mellitus, hypertension, and heart failure were the factors associated with PD prevalence.

Penile curvature after Peyronie's disease surgery: What are the risk factors?

Surgery is the golden standard for the treatment of patients with Peyronie's disease in chronic phase (12-18 months). Learning risk factors for post-surgical curvature (>20°) would aid both surgeon and patient in their decision-making process. The aim of this study was to investigate the risk factors for residual/recurrent curvatures. The clinical data of the patients, who underwent reconstructive surgery for PD between 1997 and 2016, were retrospectively reviewed. Follow-ups were performed via physical examination, surveys and phone calls. For shortening surgery (Nesbit/plication), initial bi-planar curvature was proved to be a predictor of post-operative curvature (p = .05). Lateral and ventral curvatures were associated with higher recurrence rates in patients who underwent grafting surgery (p = .01). In terms of baseline comorbidities, only diabetes mellitus had an association with curvature nonrecurrence for both shortening and lengthening surgeries (p < .05). Grafting surgery may be suggested to patients who had bi-planar curvatures instead of Nesbit surgery. Nesbit plication surgery may be preferred for patients with lateral and ventral curvatures instead of grafting surgery. Higher cavernosal blood pressures and more nocturnal erections of nondiabetic young patients might impede plication sutures and grafts and therefore increase penile curvature recurrence.

The relation between the storage symptoms before and after transurethral resection of the prostate, analysis of the risk factors and the prevention of the symptoms with solifenacin.

OBJECTIVE AND HYPOTHESIS: We aimed to investigate the reasons of storage symptoms ( SS) after transurethral resection of the prostate (TURP). The hypothesis was that a positive correlation would be identified between preoperative and postoperative SS in patients with undergoing TURP and starting early solifenacin treatment in patients with high preoperative SS would be reasonable. In addition, we aimed to analyze multiple other risk factors for post-TURP SS. MATERIALS AND METHODS: A total of 160 patients undergoing TURP were prospectively evaluated and divided into two groups according to their OABS. Those with a score of ≥10 points were Group 1 (G1), and those with < 10 points Group 2 (G2). In addition, patients in each group were randomly further divided into two subgroups: those who were started on 5 mg solifenacin succinate in the early postoperative period (G1/G2 A) and those who were not (G1/G2 B). In additions to SS Preop, perop and at the 3rd-month of postoperatively 14 variable were evaluated. The effects of these factors, surgery and the efficacy of an early medical treatment on the postoperative SS were investigated. LUTS were assessed by International Prostate Symptom Score (IPSS) and SS were assessed by sum of IPSS 2, 4 and 7 questionnaires (Storage, S- IPSS). RESULTS: Preoperative IPSS and S-IPSS were significantly higher in G1 (p< 0.001); there was a significant improvement at IPSS, S-IPSS, QoL score, Qmax, and PVR for all groups after surgery. Only preoperative S-IPSS was found to have significant effect on postoperative SS (p< 0.001). There was a significant difference between G1A and G1B but no significant difference between G2A and G2B in terms of SS at postoperatively. In addition to this, prostatic volume was found smaller than non-symptomatic patients in de novo SS patients. CONCLUSION: TURP provides significant improvement in both storage and voiding symptoms. The predictive value of the preoperative S-IPSS on postop SS is significant. These results suggest that 5 mg solifenacin succinate treatment in the early postoperative period may be beneficial for patients with high preoperative SS and may not be beneficial in others. Small prostatic volume may bode ill for postoperative SS in the patients with de novo SS.

Predictive and prognostic impact of preoperative complete blood count based systemic inflammatory markers in testicular cancer

ABSTRACT Purpose To determine the utility of preoperative complete blood count (CBC) based systemic inflammatory markers in the prediction of testicular cancer and its prognosis. Material and Methods Between 2008-2017 the data of all testicular tumor patients undergoing radical orchiectomy were retrospectively analyzed. Patient baseseline characteristics (age, tumor stage, tumor markers, etc.) and results of routine preoperative blood tests including mean platelet volume (MPV), red cell distribution width (RDW), lymphocyte ratio (LR) and neutrophil ratio (NR) were retrieved. In addition, neutrophil to lymphocyte ratio (NLR) was calculated. Results Mean age of the tumor and control group was 36.0±15 and 30.50±11 years, respectively. Mean RDW, NR and NLR were significantly higher in the tumor group with p values<0.001; whereas LR and MPV were significantly higher in the control group (p<0.001). Receiver Operating Characteristic (ROC) analyses of LR, NR, RDW, MPV, and NLR are shown in Table-3. The cut off values for RDW and NR were found as 13,7 (Area under the curve (AUC): 0.687, sensitivity = 42.2%, specificity = 84.8%) and 55.3 (AUC:0.693, sensitivity 72.2%, specificity 62%), respectively. Area under the curve for NLR in tumor group was 0.711, with a threshold value of 1.78 and sensitivity=81.8% and specificity=55.4% (AUC:0.711/sig<0.001) that together with RDW exhibited the best differential diagnosis potential which could be used as an adjuvant tool in the prediction of testicular tumor and its prognosis. Conclusion Several systemic inflammatory markers, which are obtained by routinely performed cost-effective blood tests, could demonstrate incremental predictive and prognostic information adjuvant to preoperativly achieved testiscular tumor markers.

Embarking with laparoscopic radical prostatectomy and dealing with the complications and collateral problems: A single-center experience.

OBJECTIVE: The aim of the present study was to report our single-center initial experience in laparoscopic radical prostatectomy (LRP) with special emphasis on the complications and collateral problems and their management. MATERIAL AND METHODS: A total of 48 patients (mean age 64 years) underwent LRP in our institution between August 2014 and July 2018. Two surgeons completed a fellowship training program for LRP before. Mentored operations started after the first 10 cases. The patients were divided in two groups of 30 (group I) and 18 (group II) patients. Demographic, preoperative, peroperative, and postoperative data were collected prospectively. Anesthesiology and nurses' team performances, as well as problems and their management, were reviewed. RESULTS: The demographic data for both groups (group I vs. group II) were similar. Estimated blood loss (695.5±139.23 vs. 398±339.39 mL) and intraoperative complication rates (36.66% vs. 5.55%) were significantly (p<0.05) higher in group I. Conversion to open surgery occurred in 7 (20%) patients in group I and in 1 (5.55%) patient in group II. Continence rates at 12 (83%) months were similar in both groups. Positive surgical margins were 8.33% for pT2 and 27.1% for pT3 stages. CONCLUSION: A validated fellowship program before starting LRP and performing the first cases under mentorship are helpful. The complication and conversion rates decrease after 30 cases in addition to the improved experience also with improved cooperation with the anesthesiologist and scrub nurse.

The Effectiveness of 3-D Computed Tomography in the Evaluation of Penile Deformities in Patients With Peyronie's Disease: A Pilot Study.

BACKGROUND: Anatomic and functional evaluation of the penis before treatment is very important in the choice of treatment in patients with Peyronie's disease (PD). AIM: To compare 3 different methods for the evaluation of the penile deformity, including auto-photography, combined intracavernous injection stimulation test (CIS), and 3-dimensional computed tomography (3D CT) during artificial penile erection in patients with PD. METHODS: Pretreatment penile deformities of patients with PD were compared with those detected with auto-photography, using goniometer after intracavernosal vasoactive agent, and 3D CT correlations among these 3 methods were investigated. MAIN OUTCOME MEASURES: Assessments of penile curvature with auto-photography, CIS, and 3D CT. RESULTS: The mean age of 36 patients who were included in the study was 58 ± 8.25 (36-72) years, and the mean time since the onset of the disease was 25 ± 24 months (2-144). Degrees of penile curvatures measured using auto-photography, CIS, and CT were determined as 24° (0°-80°), 40° (0°-90°), and 34° (0°-80°), respectively. When general correlation analysis was performed to evaluate the penile curvatures of all patients using 3 methods, a moderate correlation between auto-photography and both CIS (r = 0.72, P < .001) and 3D CT (r = 0.56, P < .001) was detected, whereas a strong correlation was noticed between CIS and 3D CT (r = 0.78, P < .001). When the correlation analysis between patients with and without ED was examined, a statistically significant decrease in the strength of correlation between CIS and auto-photography in patients with ED (0.629 vs 0.925, P < .05), however, was detected without any statistically significant difference in patients without ED (0.694 vs 0.813, P > .05). CONCLUSION: The superiority of 3D CT over auto-photography and its strong correlation with CIS in most parameters have been demonstrated. However, it was found that CT did not give more information than the evaluation with CIS. Current limitations and cost increases limit the use of 3D CT in the assessment of PD.

Anatomic and Functional Outcome Following Distal Shunt and Tunneling for Treatment Ischemic Priapism: A Single-Center Experience.

BACKGROUND: Ischemic priapism (IP) is a urologic emergency that requires early intervention. The main aim of IP treatment is to relieve the cavernosal pressure and provide erectile function. AIM: The aim of this study was to determine the correlation between preoperative risk factors (patient's age, duration of priapism, preoperative erectile function) and postoperative erectile dysfunction (ED). METHODS: This retrospective study consisted of 25 patients diagnosed with refractory IP between 2009-2017. The diagnosis of IP was confirmed by medical history, physical examination, and cavernosal blood gas analysis. All of the patients underwent the T-shunt procedure ± tunneling after a failed initial intervention. RESULTS: The mean age at the time of the IP diagnosis was 46.84 years (range 23-77). The average follow-up time of the study population was 40.4 months (range 3-114), and the median time from the occurrence of IP to surgery was 58 hours (range 24-240). In all cases, rapid resolution of the erection was achieved with the T-shunt ± tunneling procedure. In 1 patient, priapism recurred after 12 hours. Postoperative ED was reported by 16 (84.21%) patients, with degrees of mild, mild to moderate, and severe in 6, 1, and 9 of these cases, respectively. During the follow-up, the mean International Index of Erectile Function-5 (IIEF-5) score was 12.68 (range 5-23). Only 3 (15.78%) patients achieved successful sexual intercourse without any treatment. 6 (31.5%) patients required the aid of phosphodiesterase type 5 inhibitors, and 1 (5.26%) patient required the aid of a vacuum erection device. The 9 (47.36%) patients with severe ED failed to respond to medical treatment and were considered candidates for a penile implant. According to Kendall's tau-b correlation coefficient analysis, there was a positive correlation between the preoperative and postoperative IIEF-5 scores (P = .005), whereas the patient's age and duration of priapism were negatively correlated with the postoperative IIEF-5 score (P = .016 and P = .046, respectively). CLINICAL IMPLICATIONS: Treatment options of IP should be discussed with patients in terms of both preoperative erectile function and the duration of priapism. STRENGTHS & LIMITATIONS: The small sample size and retrospective nature of this study were the main limitations. CONCLUSIONS: Despite high success and low complication rates of T-shunt surgery, the rate of undisturbed erectile function is only 14.6%. The patient's age, the existence of preoperative ED, and the duration of priapism are associated with postoperative IIEF-5 scores. Ortaç M, Çevik G, Akdere H, et al.

The association of Intron 4 VNTR and Glu298Asp polymorphisms of the nitric oxide synthetase 3 gene and vasculogenic erectile dysfunction in Turkish men.

Several studies have focused on the impaired role of endothelial nitric oxide synthase (NOS3) gene polymorphism and its association to erectile dysfunction (ED). However, currently controversial results have been reported due to their significant heterogeneity. The present study aimed to assess the genotypic distribution and the allelic frequency of Intron 4 VNTR and Glu298Asp gene polymorphisms in vasculogenic ED patients compared to healthy controls of a specific region of Turkey. A total of 75 patients with ED (median age: 56, IQR:10.5) and 75 healthy controls (median age: 56, IQR:10.5) were prospectively analyzed. All subjects were equally evaluated by the same physician with detailed history-taking, physical examination, International Index of Erectile Function (IIEF) questionnaire, and blood tests (incl. glucose, testosterone, triglyceride and total cholesterol level). Those with an IIEF score under 26 were considered to have ED, by classifying them according to their scores as mild (22-25), moderate (11-21) and severe (1-10) ED. Color doppler ultrasonography was carried out in patients with an IIEF score <22. Hypertension, diabetes mellitus, coronary artery disease, and smoking status were significantly associated with the ED group compared to control subjects with p values of <0.001, <0.001, 0.002 and <0.001, respectively. Overall genotype frequencies was 47 (31%) a/a, 22 (15%) a/b, 82 (55%) b/b for Intron 4 VNTR and 56 (37%) GG, 78 (52%) GT, 16 (11%) TT for the Glu298Asp polymorphism. The frequencies of Intron 4 VNTR a/a allele and Glu298Asp GT allele were associated with severe ED, while a/b and TT were associated with moderate or mild, and b/b and GG were associated with no ED. In contrast to Glu298Asp, statistically significant differences in genotypic frequencies of Intron 4 VNTR gene polymorphism between ED and control subjects was established. Abbreviations: NO: nitric oxide, NOS: nitric oxide synthase, NOS3: endothelial nitric oxide synthase, NOS2: inducible nitric oxide synthase, NOS1: neuronal nitric oxide synthase, HT: hypertension, DM: diabetes mellitus, CAD: coronary artery disease, ED: erectile dysfunction, IIEF: international index of erectile function, VNTR: variable number of tandem repeats, CDU: color doppler ultrasonography, PCR: polymerase chain reaction.

Correlation of Ultrasonically Determined Bladder Wall Thickness and Prostatic Calcification With the Urinary, Psychosocial Dysfunction, Organ Specific, Infection and Neurological/Systemic Symptoms, and Tenderness Scoring System.

OBJECTIVE: To evaluate ultrasonically determined bladder wall thickness (BWT) and prostatic calcification presence, in men with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS), and to correlate the findings with patient characteristics and the urinary, psychosocial dysfunction, organ specific, infection and neurological/systemic symptoms, and tenderness (UPOINT) classification system. MATERIAL AND METHODS: Between January 2008 and December 2017, data of 1294 patients diagnosed with chronic prostatitis, in a single urology clinic, meeting a number of selective inclusion/exclusion criteria, were retrospectively analyzed. Patients, compliant to fill out all requested questionnaires, between the ages of 21-65 years were included to the study. Exclusion criteria were noncompliance of filling out required questionnaires, acute and/or chronic bacterial prostatitis, history of genitourinary cancer, history of recent prostate surgery, and diagnosis of neurological diseases affecting the bladder. RESULTS: The median patient age and UPOINT subdomain was determined as 37 (IQR = 13, range 21-65) and 2 (IQR = 1, range 0-5), respectively. Median values for BWT, National Institute of Health-Chronic Prostatitis Symptom Index (NIH-CPSI), and International Index of Erectile Function were 3 (IQR = 1, range 2-6, 7), 4 (IQR = 6, range 1-23), and 25 (IQR = 10, range 1-30), respectively. The presence of calcification demonstrated a significant association with total NIH-CPSI score and BWT, whereas its relation with age and total UPOINT score was insignificant. However in contrast to calcification status, BWT ≥3.3 showed a strong and statistically significant relation to all the described measurements. CONCLUSION: Measurement of BWT can be used as an accessible and objective method for the diagnose of CP/CPPS according to UPOINT scoring system.

Biochemical Recurrence of Prostate Cancer Presenting as Solitary Testicular Metastasis on 68Ga-Labeled Prostate-Specific Membrane Antigen Ligand Positron Emission Tomography/Computed Tomography.

Prostate adenocarcinoma (PCa) is the most frequently diagnosed malignancy in the male population, with the most common sites for secondary lesions being the lymph nodes, bones, and lungs. Testicular metastases from PCa are very rare and mostly identified incidentally after therapeutic orchiectomy for advanced PCa or during autopsy. Here we present a case involving a 64-year-old man with biochemical recurrence of castrated oligometastatic PCa that presented as solitary testicular metastasis on Ga-PSMA ligand positron emission tomography/computed tomography.

Rare Fibroepithelial Polyp Extending Along the Ureter: A Case Report

Background: Fibroepithelial polyps of the urinary tract are rare tumors, and their occurrence in the upper urinary tract is highly unusual. Case Report: This study reports a 9-year-old boy who presented to our clinic with complaints of unilateral flank pain and macroscopic hematuria. The direct urinary system graph did not show stone formation; therefore, magnetic resonance urography was performed. This revealed a filling defect in the left proximal ureter. On cystoscopy, a polyp was seen in the orifice of the left ureter, extending along the ureter. The polyp was resected by laser ablation and removed from the ureter. Histopathologic examination revealed a fibroepithelial polyp comprising fibrovascular stroma covered with transitional epithelium. Conclusion: Although extremely rare, a fibroepithelial polyp should be considered in the differential diagnosis when a young patient presents with flank pain and macroscopic hematuria. Endoscopic procedures may be the treatment of choice for polyps located in the upper ureter.

Does Mild Hydronephrosis Induced by Full-Bladder Improve Outcomes in Patients Undergoing Shock Wave Lithotripsy for Lower Calyceal Stones?: A Prospective Randomized Study.

PURPOSE: To compare the outcomes, sessions and shock wave numbers in patients undergoing standard procedure shock wave lithotripsy (SWL) and patients undergoing SWL with mild hydronephrosis induced by full-bladderfollowing oral hydration before SWL procedure for lower calyceal stones. MATERIALS AND METHODS: Between January 2014- January 2016 a total of 371 patients who underwent SWL, for lower pole calyceal stones ? 2 cm, were included into the study. 127 patients were treated in the supine position (Group A), 123 in the prone position (Group B) and 121 in the prone position with full bladder and mild hydronephrosis checked by ultrasound before procedure (Group C). There were 286 men and 85 women with a mean ± SD age of 36 ± 11 yearsResults: The mean (SD) stone sizes within the group A, group B and group C were 11 mm (±3 mm), 12 mm (±4.1 mm) and 11 mm (± 3.8 mm) respectively. No significant difference was found in age (P = .18) and stone size between 3 groups (P = .07). The median interquartile range (IQR) number of shocks within the group A, group B and group C were 7600 (3855), 6500 (4300) and 6700 (4915) respectively. Significant difference was found in number of shock waves among 3 groups (P < .01). The difference between groups according to stone expulsion rate wasfound significant in all sessions (P = .01). CONCLUSION: The present study suggests that mild hydronephrotic status induced by full-bladder before SWL can lower cost and patient discomfort by decrease in number of sessions and increase in stone clearance.

Emergency management of ureteral stones: Evaluation of two different approaches with an emphasis on patients' life quality.

OBJECTIVES: To evaluate the emergency management of obstructing ureteral calculi with two different techniques (SWL and URS) with an emphasis on patients life quality. METHODS: A total of 80 patients presenting with acute colic pain due to a single obstructing ureteral stone were treated within 24 hours following the onset of pain with two different approaches in a randomized manner. Patients requiring DJ stent placement and/or auxiliary measures after both procedures were excluded and the remaining 65 patients were evaluated [Group1: ESWL (n = 34); Group 2: URS (n = 31)]. Patients were followed during 4-weeks period with respect to the analgesic requirement, number of renal colic attacks and emergency department visits along with the HRQOL scores. RESULTS: While 26 patients treated with URS (83.9%) were stone-free, 24 cases in SWL were stone-free (70.6%) after 4 weeks. Evaluation of the cases during this follow-up period demonstrated that cases undergoing SWL required significantly higher amount of analgesics when compared with URS group (p < 0.001). In addition to the lower mean number of renal colic attacks and emergency department visits in URS group; both the mean HRQOL in terms of EQ-5D index and mean EQ-5D VAS values were also significantly higher in these cases when compared with the cases tretaed with SWL. CONCLUSIONS: Due to the negative impact of stone related events after emergency SWL on patients HRQOL, emergency URS may be applied more effectively with the advantages of prompt fragmentation of the calculi along with the immediate relief of obstruction and pain.
