RESUMEN
PURPOSE: Residual fragments not removed with urinary stone surgery may become symptomatic. In this context, this study was carried out to investigate the effect of performing retrograde intrarenal surgery, which is conventionally performed in the lithotomy position, in the modified lithotomy position (Trend-side) on stone-free rates following the surgery. METHODS: This prospective study consisted of 100 patients with a single kidney stone smaller than 2 cm between 2021 and 2023. These patients were randomized into two groups of 50 patients each to be operated on in the conventional lithotomy and Trend-side positions. Variables were compared using independent t test for continuous variables and chi-square test for categorical variables. RESULTS: There was no significant difference between the lithotomy and Trend-side position groups in terms of preoperative size, density, location of the stone, and hydronephrosis degree. Stone-free rate was 72% (n = 36) in the lithotomy group and 92% (n = 46) in the Trend-side group. Hence, there was a significant difference between the groups in the stone-free rate in favor of the Trend-side group (p = 0.009). Fragmentation time was statistically significantly shorter in the Trend-side group than in the lithotomy group (34 ± 17 min vs. 43 ± 14 min; p = 0.006). There was no significant difference between the groups in postoperative complication rates. CONCLUSION: Performing retrograde intrarenal surgery in the Trend-side position shortened the duration of fragmentation compared to the lithotomy position and was associated with higher stone-free rates. In conclusion, the Trend-side position can be safely preferred in patients undergoing retrograde intrarenal surgery due to kidney stones.

PURPOSE: To compare 90-day perioperative complications and pathological outcomes between laparoscopic radical cystectomy (LRC) and extraperitoneal radical cystectomy (EORC) approaches. MATERIALS AND METHODS: All operations were performed in a single high-volume tertiary referee center by the same surgical team.Males ≥ 18 years with pre-cystectomy clinical T1-T3 disease and having undergone an ileal conduit were included. Exclusion criteria included patients with inflammatory bowel disease, previous pelvic and/or abdominal irradiation, neo-adjuvant chemotherapy, and/or clinical T4 disease. Perioperative outcomes such as operative time, estimated blood loss, transfusion rate, hospital stay, and 90-day complications were evaluated. The recovery duration of regular bowel activity, mean stool passage,and ileus rates were recorded. RESULTS: A total of 221 patients met the inclusion criteria(81 LRC and 130 EORC). Demographics and preoperative parameters were comparable. Intraoperative estimated blood lossfavored LRC by a median of 450 mL (200-900) P=.021) vs. a median of 700 mL (300-2900) for EORC. The transfusion rate did not differ between the two groups; %14.8 (N=12) for the LRC and %20.8 (N=27) for EORC (P=.37). The median hospital stay was 9 (4-49) days for EORC and 8 (4-29) days for LRC (P=.011). The need for analgesics to control pain through an epidural catheter was higher for EORC (P=.042). There was no difference in overall complication rates (P=.47). CONCLUSION: Although LRC appears to have a slight advantage over EORC, both techniques yield satisfactory results in regard to ileus rates and 90-day perioperative complications.

OBJECTIVE: To identify atypical masturbatory behaviors (AMB) and to reveal their effects on both sexual and masturbational erection hardness in men with erectile dysfunction (ED). METHODS: Patients with ED and healthy controls were questioned about their masturbation habits. Accordingly, "rubbing in a prone position," "pressure on penis," and "masturbation through clothes" were included in the traumatic masturbation syndrome (TMS) group. Erection hardness score (EHS) is used to measure the erectile functions during masturbation (mast), foreplay (presex), and sexual intercourse (sex), separately. RESULTS: The data of 448 participants, 266 (59%) from the patient group, and 182 (41%) from the control group were analyzed. The mean ages were 30 years in both groups (p = 0.734). The rate of "rubbing in a prone position" and "penile pressure" while masturbating was higher in patients than the controls (10.2% vs. 6%, p = 0.024 and 8.6% vs. 3.3%, p = 0.0002, respectively). Patients had 2.2-fold (odds ratio, 2.21; 95% confidence interval, 1.40-3.47; p = 0.001) increased risks of having at least one AMB, compared with controls. In the secondary analysis, the patient group was divided into 2 subgroups according to having TMS (ED + TMS) or not (ED). The percentage of patients with EHS≥3 during masturbation was higher than those during sex and presex in the "ED + TMS" group (60.2%, 38.8%, and 37.2%, respectively, p = 0.0001; n = 98). Comparing the percentage of patients with EHS≥3 during mast, presex, and, sex was found to be similar in the "ED" group (58.9%, 56.5%, and 56%, respectively, p = 0.753; n = 168). CONCLUSION: Atypical masturbatory behaviors are more common in young men presenting with erectile dysfunction. These patients have higher erection hardness scores during masturbation compared to partnered sex.

Introduction: Triple D score was developed using skin-to-stone distance (SSD), stone density (SD), and stone volume (SV) for prediction of extracorporeal shockwave lithotripsy (SWL) outcomes in adults. SWL is the first-line treatment method for kidney stones <2 cm in children, however, it was not validated in the pediatric population. This article aims to validate Triple D score in pediatric patients. Materials and Methods: Of the 269 children treated with SWL between 2007 and 2021, a total of 147 children who had adequate follow-up data and evaluated with noncontrast CT before SWL were included in the study. Parameters were calculated for each of the SV, SSD, and SD variables. Receiver operator characteristic analysis was used to set cutoff values. Triple D scores were calculated, and success rates were determined for each score. Stone-free status was determined as complete clearance after 3 months of final SWL. Results: The median age of the study group was 7 years (range 1-16). Ninety-three of the 147 (63%) children had stone-free status. Mean SV, SSD, and SD values were significantly higher in the SWL-failed group than in the stone-free group after detecting cutoff values of 155 mm3, 6.5 cm, and 550 HU, respectively. Stone-free rates were detected as 23.8%, 35.1%, 74.0%, and 92.0% with the Triple D scores of 0, 1, 2, and 3 points. Conclusions: Our study confirms that Triple D scores support the SWL outcomes in the pediatric population. We believe that our research on Triple D score validation in children is of great clinical importance although various factors may affect to predict the success of SWL. IRB Approval: 2021/514/194/14.

Renal transplantation is the main treatment for end-stage kidney disease. Transplantation reduces the mortality rate and increases life quality in this population but cancer in allograft kidney is a major problem. Here, we report a 39-year male who had renal transplantation 10 years ago. On routine follow-up, radiologic imaging revealed a 32 mm mass in the allograft kidney. After partial nephrectomy, histopathologic examination revealed mucinous tubular and spindle cell variant of renal cell carcinoma(MTSCC). To our best knowledge, this is the first case in the literature that underwent partial nephrectomy in the transplanted kidney and was diagnosed with MTSCC. Key Words: Renal mass, Mucinous tubular and spindle cell tumor, Kidney transplantation.

PURPOSE: This controlled study assessed whether there was a correlation between serum total testosterone levels and bladder cancer (BCa) in terms of tumor grade and stage as objective measures in adult men. MATERIALS AND METHOD: Our prospectively-designed study included 257 patients who were diagnosed with primary BCa and its surgery between January 2017 and January 2020. Hundred and forty patients who had surgery in the same period with TUR for prostate or endoscopic ureteral stone treatment were included in the study as a control group. All patients in the study and control groups were male. The age range of the patients was between 34 and 90 years old. In order to examine groups, fasting blood glucose, lipid profile, albumin, total testosterone, and vitamin D levels of all patients included in the study. RESULTS: The relationship between tumor aggression and total testosterone level was investigated with a multinomial logistic regression model, where the control group was accepted as a reference, following adjustment for potential confounding variables, including age and serum albumin levels. Testosterone level was not found to be associated with any of the categories that determine tumor aggressiveness (p > 0.05). CONCLUSION: In the present study, there was no correlation between any categories that determine tumor aggressiveness of BCa and total testosterone levels in adult men. It is obvious that our findings should be supported and further investigations are needed.

Radical cystectomy and orthotopic neobladder are the most preferred surgical approaches for the treatment of invasive bladder cancer. Secondary tumour of ileum on neobladder is very rare. We report a 67-year man complaining of hematuria with the history of ileal neobladder for 19 years. An ileal adenocarcinoma of neobladder was detected with transurethral resection. He also had a non-functioning right kidney. A neobladderectomy. with right nephroureterectomy and ureterocutaneostomy was performed. An adenocarcinoma invading subserosal layer was reported. At six months postoperatively, patient was free of recurrence and progression. Seconder tumour of neobladder is a very rare condition. Early diagnosis and excision of neobladder may provide cure. Key Words: Bladder cancer, Urinary diversion, Cystectomy, Ileum, Adenocarcinoma.

INTRODUCTION: To avoid mesh-related complications, autologous transobturator-tape (a-TOT) technique is a viable option in stress urinary incontinence (SUI) surgery. The method differs from TOT and retropubic tape (RT) in the usage of autologous tissue. We hypothesized that a-TOT improves female sexual dysfunction (FSD) more than TOT and RT. METHODS: This is a retrospective cohort study. Patients who underwent a-TOT, TOT, and RT surgeries were surveyed regarding the cure of SUI, complications, and FSD parameters. The groups were compared according to baseline and postoperative data. RESULTS: A-TOT, TOT, and RT groups included 37, 69, and 36 patients, respectively. The median follow-up time was 19 months. The groups were similar in terms of preoperative characteristics. The objective cure, subjective cure, and overall complication rates were comparable among the groups (p > 0.05). A-TOT group had significant improvements in mean female sexual function index (FSFI) scores, TOT group deteriorated, and RT group remained stable (p = 0.001, p = 0.001, and p = 0.226, respectively). The postoperative mean total FSFI scores were 25.73 ± 2.46, 23.17 ± 3.35, and 21.53 ± 2.47 for the a-TOT, TOT, and RT groups, respectively. The a-TOT group had better results than the TOT and RT groups (p < 0.05 and p < 0.05), and besides, the difference between the TOT and RT groups was statistically significant (p < 0.05). According to percentage changes in domain scores following the operations, the a-TOT group had significantly better results in desire, arousal, lubrication, satisfaction, and pain domains than the TOT group (p < 0.05) as well as better desire, arousal, and pain domains (p < 0.05) than the RT group. DISCUSSION/CONCLUSIONS: Besides comparable outcomes in SUI treatment, the a-TOT technique provides improvements in female sexual functions while TOT worsens and RT does not change. Favorable outcomes in sexual functions caused by improvements in desire, arousal, satisfaction, and pain domains are observed following the a-TOT technique.

BACKGROUND: This study aimed to evaluate the possible effect of anterior calyceal stones on the surgical outcomes of percutaneous nephrolithotomy. METHODS: Consecutive patients with complex kidney stones from 2012 to 2020 were evaluated retrospectively. In total, 219 patients were divided into 2 groups based on the presence of anterior calyceal stones (group 1; N.=89) or not (group 2; N.=130). The groups were compared in terms of surgical outcomes (i.e., stone-free rate [SFR], operation time, and hemoglobin drop) and complications. RESULTS: The patient demographics and stone characteristics were similar between the groups. Multiple access was more frequently done in group 1 than it was in group 2 (47.2% vs. 30.8%; P=0.014), and the SFR was lower in group 1 (51.7%) than it was in group 2 (67.7%; P=0.017). Of the anterior calyceal stones in group 1, 42.6% could not be cleaned. However, when excluding patients who have only anterior residual stones from the statistical analysis, the groups had similar SFRs (68.5% vs. 67.7% for group 1 and group 2, respectively). CONCLUSIONS: The presence of complex kidney stones with anterior calyceal extension are associated with higher residual stones rates in the anterior calyx. Also, it increases multiple access, the operation time, and level of hemoglobin drop.

The potential antiviral resistance mutations within hepatitis B virus (HBV) reverse transcriptase (RT) region for nucleos(t)ide analogues (NA) are not well known. Especially, the effect of pre-existing antiviral drug resistance mutations in untreated patients in comparison to the resistance developed after treatment is not still clear. Sixteen naive chronic hepatitis B patients were studied. None of the patients had received NA treatment prior to the serum samples being collected. Forty-two potential NA resistance (NAr) mutation sites were screened by ultra-deep pyrosequencing (UDPS). After therapy, mutations conferring treatment resistance were detected by LiPA. Serum samples taken before treatment showed no classic primary or compensatory/secondary drug resistance mutations. However, NAr mutations found in 6 isolates (37.5%) involved 7 positions including rtL91I, rtT128I, rtQ215P, rtF221Y, rtN238D, rtC256S, and rtI266G. Substitutions at 3 NAr mutation sites (rtT128I, rtN238D, and rtC256S) were detected in 3 unresponsive patients developing drug resistance after NA treatment. One patient with rtI266G mutation also developed drug resistance after lamivudine (LAM) therapy. However, the relationship between rtI266G mutation and NA drug resistance was not previously reported. These results suggest that association of potential mutations besides the primary and secondary/compensatory resistance mutations should be investigated. Investigation of NAr mutations before treatment may be important for the success of the treatment.
