Can systemic immune-inflammation index and hematologic parameters aid in decision-making for active surveillance or curative treatment in low-risk prostate cancer?

INTRODUCTION: Pathologic Gleason Score (GS) upgrading is common in patients with low-risk localized prostate cancer (PCa) who are followed by active surveillance (AS) or undergo radical prostatectomy (RP). This fact raises concerns about inadequate treatment, especially in AS patients. We aimed to analyze the association of preoperative neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), and systemic immune-inflammation (SII) index with GS upgrading. MATERIALS AND METHODS: This study was approved by the Ethical Review Committee of Afyonkarahisar Health Sciences University. Data of the patients who underwent RP for PCa at three different centers between 2018 and 2023 were retrospectively analyzed. The patients were divided into 2 groups based on GR upgrading status as "upgrading" and "non-upgrading". Among the patients who underwent RP, 77 patients who fully met the criteria for AS were identified. The patients eligible for AS were divided into "non-upgrading" and "upgrading" groups. These groups were compared regarding NLR, PLR, and SII index values. RESULTS: Overall, data from 250 patients were reviewed. Among these, 147 had GS upgrading, while 103 had no upgrading. Seventy-seven patients were eligible for AS. Among these patients, 30 had upgrading, while 47 were in the "non-upgrading" group. Our analysis revealed that an NLR of 1.85 and above was associated with a 2.238-fold increase in the risk of GS upgrading (p = 0.009). Also, a PLR of 115.7 and above was affiliated with a 2.992-fold increase in the GS upgrading risk (p < 0.001). The analysis regarding patients who underwent RP but were eligible for AS revealed that an NLR of ≥1.68 was associated with a 3.25-fold risk increase in GS upgrading. On the other hand, a PLR≥134.5 and an SII index≥630.7 were affiliated with a 12.303-fold and 6.562-fold increase in the risk of upgrading (p = 0.019, p = 0.018). CONCLUSION: The decision of AS should be carefully reappraised, and treatment methods such as RP or radiotherapy should be considered in patients with high NLR, PLR, or SII index values.

Validity and Reliability of the Turkish Male Andropause Symptoms Self-Assessment Questionnaire.

Objective: This study was planned to examine the validity and reliability of the Turkish version of the Male Andropause Symptoms Self-Assessment Questionnaire (MASS-Q). Materials and Methods: One hundred and twenty-five men with a mean age of 54.24 ± 6.51 years participated in the study. First, participants' demographic data were recorded. Then, the MASS-Q was adapted to Turkish. The assess the reliability and validity of the Turkish MASS-Q, internal consistency, test-retest reliability, and criterion validity analyses were administered. For the reliability test, the scale was readministered 1 week later. Test-retest reliability was examined with the intraclass correlation coefficients (ICCs). Internal consistency was defined by Cronbach's alpha. Regarding the validity analysis, content validity was determined according to expert opinions. For criterion validity, the Aging Male Symptoms-Questionnaire (AMS-Q) was used. Results: According to the results of the analysis, the ICC values between the test-retest scores of the total and subdimensions (sexual, somatic, psychic, and behavior) of the MASS-Q were found to be 0.987, 0.939, 0.973, 0.951, and 0.887, respectively (P < 0.05). Cronbach's alpha values of the total and subdimensions (sexual, somatic, psychic, and behavior) of the MASS-Q were calculated as 0.924, 0.870, 0.747, 0.865, and 0.667, respectively. According to the ICC values obtained, it was found that the MASS-Q had a high degree of reliability. According to the internal consistency results, the sexual and psychic subdimensions were found to be quite reliable, whereas the somatic and behavioral subdimensions were found to be sufficiently reliable. According to the criterion validity results, a very high and high correlations were found between the AMS-Q scores and the MASS-Q scores (r = 0.636-0.938, P = 0.001). Conclusion: As a result, it was determined that the Turkish version of the MASS-Q is a valid and reliable scale that can be used in Turkish men.

Effect of systemic isotretinoin therapy on semen parameters.

PURPOSE: Vitamin A has multiple functions in the human body, being involved in growth, epithelial differentiation, vision, immune function and reproduction. While normal spermatogenesis is influenced by several factors, it requires vitamin A. Systemic isotretinoin is a vitamin A derivative that is used in the treatment of many dermatological diseases, especially acne vulgaris (AV). There is limited research on the changes in semen parameters after systemic isotretinoin therapy in humans. Our study investigates the presence of varicoceles in patients undergoing systemic isotretinoin therapy for AV and examines whether there were any changes in the semen parameters before and after treatment. METHODS: Included in the study were 46 men patients who were scheduled for systemic isotretinoin therapy for AV. Before treatment, the patients underwent a physical examination and ultrasonography for varicoceles assessment. The patients underwent spermiogram before treatment and after 6 months of treatment. The spermiogram assessments included semen volume, sperm concentration, total sperm count, progressive motility, viability and sperm morphology. RESULTS: After treatment, there was an increase in semen volume, sperm concentration, total sperm count, progressive motility and vitality from the pre-treatment values, but a deterioration in the sperm morphology (p < .05). Comparing patients with and without varicoceles revealed more changes in semen parameters after treatment in those with varicoceles. There was a statistically significant difference in sperm concentration (p < .001). CONCLUSIONS: Systemic isotretinoin therapy negatively affects sperm morphology, but has positive effect on other semen parameters, and these changes in semen parameters occur more frequently in patients with varicoceles.KEY MESSAGESAcne vulgaris is a very common disease and systemic isotretinoin is used as the most effective agent in its treatment.Systemic isotretinoin positively affects semen parameters except sperm morphology.Changes in semen parameters are more common in patients with varicocele.

Effect of the COVID-19 Pandemic on Radical Prostatectomy: A Turkish Multicenter Study.

OBJECTIVE: The present study examines the effects of the coronavirus disease 2019 pandemic on radical prostatectomy performed as part of localized prostate cancer treatment in Turkey. MATERIAL AND METHODS: A retrospective analysis was made of the data of 176 patients from 8 centers in Turkey who underwent radical prostatectomy due to localized prostate cancer over the 2 years spanning March 1, 2019, to February 28, 2021. Within this timeframe, March 1, 2019, to February 28, 2020, was denoted the 1-year pre-coronavirus disease 2019 period, while March 1, 2020, to February 28, 2021, was denoted the 1-year coronavirus disease 2019 period. An analysis was made of whether there was a difference in the number of radical prostatectomies performed for prostate cancer, the time from biopsy to operation, and the biopsy and radical prostatectomy pathology between the 2 periods. RESULTS: It was found that the number of radical prostatectomies performed for localized prostate cancer during the coronavirus disease 2019 pandemic was statistically and highly significantly fewer than in the pre-coronavirus disease 2019 period (P <.001). The patients diagnosed with Gleason 3+3 (low risk) prostate cancer were statistically significantly fewer in number in the coronavirus disease 2019 period (P <.001). The pathological Gleason score was upgrading than the biopsy Gleason score in all patients who underwent in both periods (P <.001). When the periods were compared, the pathological involvement determined by lymph node dissection performed during radical prostatectomy was found to be decreased in the coronavirus disease 2019 period, although the difference was not statistically significant (P =.051). CONCLUSION: As with many diseases, the diagnosis and treatment of prostate cancer have been adversely affected by the coronavirus disease 2019 pandemic.

Utilization of Internet Resources by Surgeons for Continuous Professional Development in the Era of Prevailing COVID-19 Pandemic: Trends and Obstacles.

Background: To investigate the use of internet resources by surgeons for continuing professional development (CPD). Results: This cross-sectional study was carried out between July 1, 2021, to October 31, 2021, at the Department of Medicine, Health Sciences University Diskapi Yildirim Beyazit Training and Research Hospital, Ankara, Turkey, with participants from nine surgical specialties: General surgery, neurosurgery, orthopedics, urology, plastic surgery, ear-nose-throat surgery, cardiovascular surgery, ophthalmology, and anesthesiology. All study participants were asked to complete a questionnaire comprising 23 questions regarding their age, duration of work experience, appointment status, venue, and time spent on internet resources and preferred online resources for CPD purposes. In addition, participants were divided into two groups according to their appointment status: academic faculty and staff surgeons. Data analysis was performed using IBM SPSS Statistics version 17.0. The target population consisted of 216 specialists. The survey was completed by 204 (94.4%) surgical specialists. The majority of the specialists (n = 137, 67.2%) reported using the internet for work-related purposes every day. Daily time spent on internet resources was reported to be 30-60 min by 39.2% (n = 80) participants, whereas 52 (25.5%) reported spending less than 30 min. The participants wished to spend more time on internet resources. The majority of surgeons found the hospital and home equally effective in using the internet and preferred to engage alone. The mean age, English language level, usage of online resources, and the attitude score toward the perceived credibility and usefulness of e-resources were significantly higher in the academic faculty group than staff surgeons (p < 0.005). On the other hand, the use of Google/Google scholar was similar between the two groups (p = 0.192). Technical difficulties such as slow internet, need for website registration, and article fees were considered drawbacks for internet resources among all the participants. Conclusions: This study showed that most surgeons use internet resources daily for CPD and stated they would like to engage longer despite technical difficulties. Institutions should address these technical difficulties.

The Association of Penile Fracture and Female Sexual Abnormalities.

PURPOSE: To study the effect of female sexual abnormalities on the etiology of penile fracture, which is an important urological emergency. MATERIALS AND METHODS: The sexual function of the partners of patients with penile fracture (study group, n = 90) treated at our clinic and healthy women (control group, n = 90) were evaluated on a voluntary basis. In both groups, sexual function was evaluated with the Female Sexual Function Index (FSFI). Each substance of the FSFI was evaluated separately by comparing both groups and the effect on the development of penile fracture was investigated. RESULTS: There was no difference in demographic and clinical characteristics between the study and control groups. Evaluation of sexual function with FSFI revealed that the scores of vaginal lubrication, orgasm, satisfaction, and pain subscales were lower in the study group (p < .001). Among these subscales, anorgasmia was determined as the factor with the largest effect on the development of penile fracture (OR = 7.333, 95% CI = 2.666-20.166, p < .001). No correlation was found between the largest dimension of penile fracture and FSFI total and subscale scores in the study group. CONCLUSION: We believe that female vaginal dryness and dyspareunia in particular are factors which could cause the development of penile fracture during sexual intercourse. The treatment could prevent the development of penile fracture in the male.

The Effect of Health Literacy on Men Seeking Medical Attention for Erectile Dysfunction.

Objective In this study, we aimed to determine if there was any relationship between patients with erectile dysfunction (ED) who do not seek medical help at the hospitals and their health literacy (HL) levels. Materials and methods The study included 68 patients. Patients with a main complaint of ED were included in Group 1, and those with benign prostatic hyperplasia (BPH) or who requested an age-related check-up were included in Group 2. Questions 1-5 and 15 of the International Index of Erectile Function (IIEF)-15 scale evaluating erectile functions were collected as IIEF-6 for the purpose of this study. Severe ED was defined as having a score of 0-10, while moderate ED was defined as a score of 11-16. Both patients with severe and moderate ED were considered and included in the study. The European Health Literacy Scale (HLS-EU) and the Turkey Health Literacy Scale-32 (THLS-32) were used for the evaluation of HL. Results The HLS-EU person-specific mean index was found to be 37.22 ±5.29 in Group 1 and 30.46 ±6.32 in Group 2. The THLS-32 person-specific mean index was determined to be 37.68 ±5.41 in Group 1 and 30.94 ±6.13 in Group 2. In Group 1, 58.3% of patients were classified as having sufficient HL and 22.2% were classified as having excellent HL. In Group 2, 21.9% of patients were classified as having sufficient HL and 3.1% were classified as having excellent HL. Conclusions As societal income, education levels, and HL levels increase, ED will become more important to individuals, motivating them to seek timely medical attention, and thereby leading to earlier diagnoses of potential primary pathologies.

Comparison of semirigid ureteroscopy, flexible ureteroscopy, and shock wave lithotripsy for initial treatment of 11-20 mm proximal ureteral stones.

OBJECTIVE: We aimed to retrospectively evaluate the effectiveness and safety of flexible ureteroscopy (f-URS), semirigid ureteroscopy (sr-URS), and shock wave lithotripsy (SWL) to treat single 11-20 mm stones in the proximal ureter. MATERIALS AND METHODS: Patients treated at our clinic for 11-20 mm single stones in the proximal ureter who underwent f-URS, sr-URS or SWL as initial lithotripsy methods were compared in terms of their clinical characteristics and treatment outcomes. RESULTS: A comparison among 201 patients who had undergone f-URS, 119 patients who had undergone sr-URS, and 162 patients who had undergone SWL showed no significant baseline differences in patients' demographic and stone characteristics. Stone-free rates on the 15th day and 3rd month were higher with f-URS (89.6% and 97%, respectively) than with sr-URS (67.2% and 94.1%, respectively) and SWL (41.4% and 79.0%, respectively; all p < 0.001). Retreatment rates were significantly higher with SWL than with the other two modalities (p < 0.001); auxiliary procedure rates were significantly lower with f-URS than with the other two modalities (p < 0.001). Treatment-related complication rate at the end of the 3rd month was lower with f-URS than with SWL (p = 0.022). Furthermore, f-URS was more effective than sr-URS for treating impacted stones. CONCLUSIONS: We found that f-URS was highly successful as an initial lithotripsy procedure for medium-sized proximal ureteral stones, and it helped achieve early stone-free outcomes with a lower need for retreatment and auxiliary procedures, lower complication rates, and higher effectiveness on the impacted stones compared with sr-URS and SWL.

Is RIRS Safe and Efficient In Patients With Kidney Stones Who Had Previous Open, Endoscopic, or Percutaneous Kidney Stone Surgery? One Center Retrospective Study.

PURPOSE: In our study, we assessed the efficiency and reliability of retrograde intrarenal surgery secondary to open surgery for kidney stone treatment. Moreover, we compared the efficiency and safety of retrograde intrarenal surgery for the patients with previous history of open surgery, percutaneous nephrolithotomy, secondary retrograde intrarenal surgery (RIRS) and primary RIRS. MATERIALS AND METHODS: Data was retrospectively reviewed. Patients who had kidney anomalies, who had been stented due to ureteral stricture in the operation and who were < 18 years old, were excluded. There were 30 patients who underwent RIRS secondary to open surgery. The demographic and stone characteristic as well as intraoperative and postoperative data of the patients were recorded. 30 patients with similar demographic and stone characteristics to those patients were selected by match pairing method from patients who had previous PNL, RIRS history and had undergone primary RIRS. A total of 120 patients, in total 4 groups, were included in the study. RESULTS: Statistically significant difference was detected among the groups with regards to shock wave lithotripsy history and preoperative JJ stent rate. There was no statistically significant difference in terms of stone characteristics, intraoperative and postoperative data. CONCLUSION: RIRS is an efficient and safe method for kidney stone treatment of the patients with previous history of open surgery, percutaneous nephrolithotomy and retrograde intrarenal surgery. It has a similar efficiency and safety for the patients who have undergone retrograde intrarenal surgery. This is the first study that compares the patients especially  with different previous surgery methods.

Is Tamoxifen Use a Factor Affecting Continence in Breast Cancer Patients?

INTRODUCTION:  Tamoxifen treatment has been shown to reduce the recurrence and mortality rates in hormone receptor-positive breast cancers independent from chemotherapy. This benefit increases with the prolongation of the use of tamoxifen but with increasing side effects. In this study, we aim to evaluate the presence of urogenital symptoms in breast cancer patients on tamoxifen and compare them with those who are not on any hormonotherapy. MATERIALS AND METHODS: This study was performed on patients diagnosed as early-stage breast cancer. The study group consisted of hormone receptor-positive patients given tamoxifen as adjuvant hormonal therapy. The control group consisted of breast cancer patients who had no hormonotherapy. Patients with a complaint of urinary incontinence with onset after tamoxifen usage were evaluated with Urogenital Distress Inventory Short Form (UDI-6), Incontinence Impact Questionnaire Short Form (IIQ-7) and Incontinence Quality of Life Questionnaire (I-QOL). RESULTS: A total of 137 early-stage breast cancer patients were included in this study; 74 estrogen receptor-positive patients on tamoxifen therapy (study group) and 63 hormone receptor-negative patients with no hormonotherapy (control group). The median age was 44 (30-65) years for tamoxifen users and 49 (27-64) years for the control group. The stages of the patients were similar for both groups. 78.4% of the women in the tamoxifen group and 49.2% in the control group were in the premenopausal period. The groups were similar in regard to body mass index and parity. The complaint of urinary incontinence was more frequent in the study group compared to controls (39 (52.7%) vs. 5 (7.9%)). Women with the complaint of urinary incontinence were evaluated with self-reported UDI-6, IIQ-7 and I-QOL forms and the scores were similar for both study and control groups. A statistically significant relation was observed between cigarette smoking and the presence of urinary incontinence. The percentages of smokers were 50% of those with incontinence and 24.7% of those without incontinence. CONCLUSION: Urinary incontinence is positively correlated with tamoxifen usage in early-stage breast cancer patients.

May High Levels of Systemic Immune-Inflammation Index and Hematologic Inflammation Markers Suggest a Further Stage in Testicular Tumours?

INTRODUCTION: Due to variety of treatment alternatives for testicular tumours, parameters other than existing staging criteria are also needed. Most studies have revealed the correlation between cancer and inflammation. In this study, we aimed to investigate the value of preoperative inflammatory markers between early-stage testicular tumours and patients with advanced-stage, their relationship with tumour pathology and their importance in predicting stage. To calculate the differences between inflammatory markers, stage 1 tumours localized to the testis and advanced-stage tumours spread beyond the testis were classified into 2 groups according to tumour pathology. MATERIALS AND METHODS: The data of 112 patients undergoing inguinal orchiectomy in between 2008 and 2018 were recorded retrospectively. Neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), lymphocyte-to-monocyte ratio (LMR) and systemic immune-inflammation index (SII) were calculated by using the numbers of blood cell counts based systemic markers of inflammation. The differences between markers of inflammation were calculated by dividing tumours into 2 groups including early-stage and advanced- stage testicle tumours. RESULTS: According to the results of preoperative inflammatory markers in predicting the stage; in the seminoma group, the difference between the median NLR (2.37 vs. 4.39, p = 0.012), LMR (3.80 vs. 2.40, p = 0.018) and SII (612 vs. 1,127, p = 0.009) of stage 1 and advanced stage were statistically significant, while in the non-seminoma group, only the difference between median PLR (99 vs. 154, p = 0.002) of stage 1 and advanced stage was statistically significant. Sensitivity and specificity of predicting advanced stage according to cut-off values of markers were 69 and 75% in NLR (3.21), 83 and 75% in LMR, and 59 and 75% in SII in the seminoma group; on the other hand, in the non-seminoma group, the sensitivity, and specificity of predicting the advanced stage of PLR cut-off (104) were 71 and 88% respectively. CONCLUSIONS: The clinical use of inflammatory biomarkers in testicular tumours may represent an important step in understanding germ cell tumours biology and in supporting staging criteria and prognostic criteria.

Retrograde Intrarenal Surgery Following Laser Endopyelotomy; Sequential Procedures for Ureteropelvic Junction Obstruction and Nephrolithiasis.

PURPOSE: This study was designed to evaluate the effectiveness and safety of retrograde intrarenal surgery (RIRS)following retrograde laser endopyelotomy (rLEP) in concomitant ureteropelvic junction obstruction (UPJO) andstone disease. MATERIALS AND METHODS: Patients with concomitant UPJO and renal stone disease who were first treated in ourclinic by rLEP for obstruction and then RIRS for stone disease were enrolled. Study period went from 2012 to2017. RIRS following rLEP was performed earliest at the sixth week. Patients who underwent rLEP were matchedwith those with normal anatomy at a 1:1 ratio based on the propensity scores. Additionally, clinical results werecompared in order to evaluate the effects of rLEP surgery on RIRS. Subsequently, patients who underwent RIRSfollowing rLEP were independently evaluated and factors affecting the success of sequential procedures wereinvestigated. RESULTS: The sole difference between those that underwent RIRS following rLEP (n=27) and controls with normalanatomy that underwent RIRS was in operative times (p = .011). Evaluation of potential success factors inthe sequential rLEP-RIRS group revealed that primary etiology, obstruction length less than 1cm, smaller stonesize and presence of single stone showed significant effects (p = .047, p = .030, p = .040, p ? .001, respectively).RIRS following rLEP generated an 81.5% stone-free and, after a median follow-up time of 32 months, a 74.1%obstruction-free rate. CONCLUSION: RIRS following rLEP in patients with UPJO and renal stones is an effective treatment method. It canbe used safely in patients with single stones < 2cm, short obstruction lengths, and presence of primary etiology.

Effect of histopathologic characteristics on pseudocapsular invasion in the case of partial nephrectomy for renal tumours.

OBJECTIVE: It is aimed to define the existence of pseudocapsular structure on renal tumours, illuminate the relation between pseudocapsular invasion and Fuhrman grade histological type that are among histopathologic prognostic risk factors and determine the relation between surgical margin positivity and existence of pseudocapsular invasion. Sequential partial nephrectomy series and relevant pathological preparations were retrospectively reviewed in order to evaluate these issues. METHODS: The study includes 123 patients diagnosed with T1 renal tumour and treated with partial nephrectomy in between January 2007 and June 2016. Benign angiomyolipoma was excluded due to complete non-existence of pseudocapsule. 99 T1 patients diagnosed with renal cell cancer whose pathological slides can be duly analysed were included in the study. Clinical and pathological details were evaluated for all patients. Existence of pseudocapsule was revealed for all patients. Pseudocapsule invasion was classified by existence of expansive and infiltrative type and non-existence of pseudocapsule invasion. The groups have been assessed by their histopathologic characteristics. RESULTS: Compared to the group in which pseudocapsular invasion was not detected, clear-cell histological subtype was observed more frequently in a statistically significant way in the group with expansive pseudocapsular invasion and infiltrative pseudocapsular invasion respectively (p = 0.017 and p < 0.001). Pathological tumour sizes were found out to be statistically similar (p = 0.874). There was not a statistically significant difference in terms of Fuhrman grade (p = 0.220). There was not a statistically significant difference in terms of surgical positive margin (p = 0.609). CONCLUSION: It was indicated in our study that only the histological subtype affected pseudocapsular invasion in group of patients treated with partial nephrectomy but tumour size, tumour stage, tumour location as well as endophytic and exophytic character did not affect invasion. It has also been revealed that surgical margin positivity is not correlated with pseudocapsular invasion.

The Association of Encrustation and Ureteral Stent Indwelling Time in Urolithiasis and KUB Grading System.

PURPOSE: To evaluate the management of prolonged indwelling ureteral stents and the newly developed KUB (kidney, ureter, and bladder) grading system for the classification of encrusted stents in urolithiasis. METHOD: This study involved 69 patients that had indwelling and forgotten ureteral stents for more than 6 months after urolithiasis treatment. They were categorized into 4 groups based on indwelling time and were reviewed retrospectively. Patients whose ureteral stent could not be removed with simple cystoscopy were graded according to stone surface area and the KUB system. RESULTS: The mean stent indwelling time was 23.1 months. Stone burden in KUB and, in proportion to that, total KUB (T) score showed increased association that was directly proportional to indwelling time (p < 0.001, p = 0.008). Surgical intervention was required in 73.9% of patients. Among patients requiring surgery, 78.4% were treated in a single session and multi-modal interventions were performed in 70.5%. K score ? 3 was found to be associated with multiple surgery requirements (odds ratio [OR];11.25, %95 confidence interval [CI]:2.132-59.375),multi-modal procedure requirements (OR;16.50, %95 CI:3.434-79.826 ), and lower stone-free rates (p = 0.04). Bscore ? 3 was associated with multi-modal procedure requirements (OR;8.90, %95 CI:1.052-75.462). U score ? 3and T score ? 9 were associated with an operating time >180 minutes (p < 0.001, p = 0.008). CONCLUSION: Prolonged indwelling time of the ureteral stent in urolithiasis is associated with increased encrustation and stone burden. Since the KUB system specifies stone burden and its particular localization, it can be used as a simple, convenient method for the planning treatment of encrusted ureteral stents.

Bilateral intra-abdominal testicular tumor: Case report.

INTRODUCTION: Bilateral intra-abdominal testis is a very rare clinical entity. These testes may develop cancer in an adult patient with empty scrotum. CASE PRESENTATION: A case of a huge intra-abdominal solid mass in a 32-year-old gentleman is presented. Physical examination revealed an empty scrotum. Laboratory investigations, imaging studies, laparotomy and histopathological examination showed that the solid mass was a mixed germ cell tumor of the left testis. The contra-lateral testis also had a tumor. Resection of the solid mass and contra-lateral orchiectomy was performed. Adjuvant chemotherapy was given. Six months after surgery, his follow-up parameters were all within normal limits. DISCUSSION: Since bilateral intra-abdominal testis tumor is a very rare clinical entity, there are no patient management guidelines available. Management strategies differ significantly among groups and they are based mainly on the experience reflected in the context of anecdotal case reports. CONCLUSION: Surgical exploration and adjuvant chemotherapy seems as a reasonable treatment option in the setting of bilateral intra-abdominal testis tumor in an adult patient.

Percutaneous Nephrolithotomy Performed on the Kidney Stone in a Patient With Ankylosing Spondylitis: A Case Study.

A 68-year-old man with serious cervical kyphosis and dorsolumbar scoliosis due to ankylosing spondylitis was admitted with a stone 17 mm in size in left kidney lower calyx. A percutaneous nephrolithotomy operation was decided considering the size and location of stone and the anatomical deformities of patient. The kidney was accessed through monoplaner triangulation method by giving a special position of the patient's spinal deformity and stone was successfully removed. Percutaneous nephrolithotomy is a feasible method in ankylosing spondylitis patients in case that the right position is achieved. Each patient should be assessed individually deciding on treatment methods.
