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.

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.

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.

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.

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. 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. 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. 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.
