Abstract
OBJECTIVE To compare the effects of monopolar and bipolar energy sources on efficacy of both techniques and possible complications in bladder cancer patients undergoing repeat Transurethral resection of bladder tumour (re-TURBT). STUDY DESIGN Descriptive study. Place and Duration of the Study: University of Health Science, Izmir Bozyaka Research and Training Hospital, Turkiye, from 2019 to 2021. METHODOLOGY Patients undergoing re-TURBT were inducted. Patients with residual tumour at initial TURBT, recurrent bladder cancer and patients with a non-urothelial pathology report in initial TURBT were excluded. The primary outcome was the complication ratio of the TURBT which were obturator reflex, bladder wall perforation, coagulum retention, fever, and TUR syndrome. The secondary outcome was the efficacy of the TURBT procedure, such as complete tumour resection, adequate sampling of deep muscle tissue, and sampling of qualified tissues without any thermal damage. RESULTS One hundred and twenty-three patients were enrolled; 75 patients in re-M-TURBT group and 48 patients in re-B-TURBT group were analysed. Demographic and tumour characteristics, and complication rates according to the Clavien classification, were similar between the two groups (p = 0.302). The catheterisation time was shorter significantly in the bipolar re-TURBT group (median 4 vs. 3 days, respectively, p = 0.025). CONCLUSION Monopolar and Bipolar energy sources are techniques that can be used safely in re-TURBT in terms of both appropriate pathology sampling (adequate muscle tissue sampling, cautery artifact) and complication (obturator reflex, hyponatraemia, haemoglobin decrease, bleeding) rates. KEY WORDS Bladder Cancer, Monopolar, Bipolar, TURBT, Obtrator reflex, Complications.

Predictive Role of the Systemic Immune Inflammation Index for Intravesical BCG Response in Intermediate- and High-Risk Non-Muscle-Invasive Bladder Cancer. Urol Int 2023:1-7. [PMID: 36809748 DOI: 10.1159/000528740] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2022] [Accepted: 12/12/2022] [Indexed: 02/24/2023]
Abstract
INTRODUCTION In this study, we aimed to explore using the predictive role of systemic immune inflammation index (SII) for responses of intravesical Bacillus Calmette-Guérin (BCG) therapy in patients with intermediate- and high-risk non-muscle-invasive bladder cancer (NMIBC). METHODS From 9 centers, we reviewed the data of patients treated for intermediate- and high-risk NMIBC between 2011 and 2021. All patients enrolled in the study presented with T1 and/or high-grade tumors on initial TURB had undergone re-TURB within 4-6 weeks after initial TURB and had received at least a 6-week course of intravesical BCG induction. SII was calculated with the formula SII = (P × N)/L, where P, N, and L refer to peripheral platelet, neutrophil, and lymphocyte counts, respectively. In patients with intermediate- and high-risk NMIBC, the clinicopathological features and follow-up data were evaluated to compare SII with other systemic inflammation-based prognostic indices. These included the neutrophil-to-lymphocyte ratio (NLR), platelet-to-neutrophil ratio (PNR), and platelet-to-lymphocyte ratio (PLR). RESULTS A total of 269 patients were enrolled in the study. Median follow-up time was 39 months. Disease recurrence and progression were observed in 71 (26.4%) and 19 (7.1%) patients, respectively. For groups with and without disease recurrence in terms of NLR, PLR, PNR, and SII calculated prior to intravesical BCG treatment, no statistically significant differences were observed (p = 0.470, p = 0.247, p = 0.495, and p = 0.243, respectively). Moreover, there were also no statistically significant differences between the groups with and without disease progression in terms of NLR, PLR, PNR, and SII (p = 0.504, p = 0.165, p = 0.410, and p = 0.242, respectively). SII did not show any statistically significant difference between early (<6 months) and late (≥6 months) recurrence (p = 0.492) and progression groups (p = 0.216). CONCLUSION For patients with intermediate- and high-risk NMIBC, serum SII levels do not present as an appropriate biomarker for the prediction of disease recurrence and progression following intravesical BCG therapy. A possible explanation for the failure of SII to predict BCG response may be found in the impact of Turkey's nationwide tuberculosis vaccination program.

Abstract
INTRODUCTION AND OBJECTIVES To evaluate whether there is any difference between immediate postoperative instillation of intravesical chemotherapy (IPOIC) and continuous saline bladder irrigation (CSBI) in terms of bladder cancer (BC) recurrence in patients with primary low- or intermediate-risk non-muscle-invasive BC (NMIBC). MATERIALS AND METHODS Medical records of 1482 patients who underwent transurethral resection of bladder tumor between March 1994 and August 2020 were reviewed retrospectively. Patients were divided into two groups according to IPOIC and/or CSBI administration status [Group-1 = CSBI alone; Group-2 = CSBI following IPOIC]. Low- and intermediate-risk NMIBC patients were also divided into subgroups according to IPOIC and/or CSBI administration status. RESULTS A total of 594 patients with primary NMIBC were included. Of the patients, 86 (14.5%) were female and 508 (85.5%) were male with a median age of 69 (60-78) years. The frequency of patients in Group-1 and Group-2 were 361 (60.8%) and 233 (39.2%), respectively. Recurrent disease was observed in 213 (35.9%) patients. There was no difference between the groups when they were compared for recurrent disease frequency, median time to first recurrence and frequency of recurrence within first 12 months (P = .064, P = .671, and P = .145, respectively). Disease recurrence rates in low-risk NMIBC patients was lower when they were treated with "CSBI following IPOIC" when compared to "CSBI alone" (P = .042). However, no difference was observed in low-risk NMIBC subgroups when they were compared for pathological features of recurrent tumors such as number, size, grade, stage, and presence of carcinoma in situ (P > .05, for each). CONCLUSIONS "CSBI following IPOIC" combination was not superior to "CSBI alone" for preventing adverse pathological outcomes in recurrent low- and intermediate-risk NMIBC.

Is laparoscopic adrenalectomy for pheochromocytoma safe and effective in geriatric patients? Int J Clin Pract 2021; 75:e14427. [PMID: 34081829 DOI: 10.1111/ijcp.14427] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/20/2020] [Revised: 05/24/2021] [Accepted: 05/27/2021] [Indexed: 01/18/2023] Open
Abstract
OBJECTIVES The study aimed to assess the haemodynamic changes of laparoscopic adrenalectomy (LA) in geriatric patients with pheochromocytoma (PHEO). To the best of our knowledge, this is the first study to evaluate the haemodynamic outcomes of LA in this patient population. METHODS Data of 350 patients who underwent single-side transperitoneal LA between 2000 and 2020 were reviewed retrospectively. Patients with a histopathological diagnosis of PHEO were included in the study and classified into two groups according to their ages at the date of surgery. Patients older than 65 years were accepted as elderly according to the World Health Organisation (WHO) recommendations. RESULTS A total of 54 patients underwent LA for PHEO. Fifteen patients were enrolled in the elderly and 39 in the young groups. There were no significant differences in terms of the operation site (0.564), tumour size (0.878), perioperative results such as mean anaesthesia; operation times, blood loss and haemodynamic changes. There were no significant differences in mean hospitalisation and intensive care unit times. One patient in both groups had grade 1 complication according to Clavien Dindo classification (prolonged ileus, managed with medical treatment and transfusion during surgery, respectively). CONCLUSION Young and elderly patients had similar outcomes in terms of haemodynamic changes that occurred with LA. LA in elderly patients with PHEO is as safe and effective as in younger patients.

Abstract
INTRODUCTION The aim of the present prospective-randomized study was to compare perioperative outcomes and complications of bipolar and monopolar TURBT for lateral wall-located non-muscle invasive bladder cancers (NMIBC) under obturator nerve block (ONB). PATIENTS AND METHODS 80 patients who underwent TURBT for lateral wall-located primary bladder tumors under ONB from March, 2016 to November, 2019 were included in the present study. The patients were randomized equally into two groups; monopolar TUR (M-TURBT) and bipolar TUR (B-TURBT). The primary and secondary outcomes were safety (obturator jerk and bladder perforation) and efficacy (complete tumor resection and sampling of the deep muscle tissue). RESULTS Obturator jerk was detected in 2 patients (5%) in M-TURBT while obturator jerk was not observed during B-TURBT (p=0.494). Bladder perforation was not observed in both groups. All of the patients underwent complete tumor resection. There was no significant difference in muscle tissue sampling (67.5% vs. 72.5%, p=0.626) and thermal tissue damage rates (12.5% vs. 25%, p=0.201). The majority of complications were low-grade and the differences in Clavien grade 1-3 complications between groups were not statistically significant. CONCLUSION In the treatment of lateral-wall located NMIBCs, either M-TURBT or B-TURBT can be safely and effectively performed by combining spinal anesthesia with ONB. Even so, it should be taken into consideration that low-grade postoperative hemorrhagic complications may occur in patients who undergo M-TURBT.

Abstract
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.

Abstract
Purpose To investigate the clinical and pathological predictive factors affecting biochemical recurrence (BCR) after radical prostatectomy (RP) in patients with positive and negative surgical margin (SM). Methods Patients who underwent RP were retrospectively reviewed for the study. Demographic, clinical, pathological and oncological data were evaluated. All data were compared between patients with positive SM and negative SM to detect factors associated with SM status. Later, patients were divided into two groups as BCR-negative and BCR-positive groups. Data were separately compared between BCR groups for all patients, SM-negative and SM-positive patients, respectively. Results A total of 254 patients with a mean age of 63.5 years and the mean prostate-specific antigen of 10.9 ng/ml were evaluated in the study. SM positivity was found to be an independent prognostic factor for BCR (p = 0.013, Odds Ratio (OR): 0.267, 95% Confidence Interval (CI): 0.094-0.755). In SM-positive patients, biopsy Gleason Score and International Society of Urological Pathology grade were found to be independent predictive factors for BCR (p < 0.05). However, only tumor to SM distance (TSMD) was found to be an independent risk factor for BCR (p = 0.024) in SM-negative patients. The predictive cutoff value of the TSMD was found to be 75 μm for BCR (100% sensitivity and 63.9% specificity) (AUC = 0.803, p = 0.024). Although all of 46 patients with >75 μm TSMD were recurrence free, 5 of 31 patients with <75 μm TSMD had BCR (p = 0.009; OR: 0.839 CI: 0.719-0.979). Conclusion High Gleason Score and International Society of Urological Pathology grade of biopsy were found to be associated with BCR in SM-positive patients. For SM-negative patients, only TSMD was found to be associated with BCR after RP.

Abstract
INTRODUCTION To compare the perioperative outcomes and complications of monopolar and bipolar transurethral resection of bladder tumors (TURBT) in patients with coronary artery disease (CAD). MATERIALS AND METHODS A total of 90 CAD patients with newly diagnosed bladder cancer who underwent TURBT were randomized into monopolar TURBT (M-TURBT) and bipolar TURBT (B-TURBT) groups. Primary outcome was safety of the procedures including obturator jerk, bladder perforation, clot retention, febrile urinary tract infection and TUR syndrome. The secondary outcome was the efficacy of TURBT procedures, including complete tumor resection, sampling of the deep muscle tissue and sampling of the qualified tissues without any thermal damage. RESULTS Mean ages of the patients in M-TURBT and B-TURBT groups were 71.36±7.49 and 73.71±8.15 years, respectively (p=0.157). No significant differences were found between M-TURBT and B-TURBT groups regarding complete tumor resection (76.2% vs. 87.5%, p=0.162) and muscle tissue sampling rates (71.4% vs. 64.6%,p=0.252). Obturator jerk was detected in 16.7% of the patients in M-TURBT group and 2.1% in B-TURBT group (p=0.007). No statistically significant differences were found between the groups regarding intraoperative and postoperative complications. CONCLUSIONS Both monopolar and bipolar systems can be used safely and effectively during TURBT procedure in CAD patients. Due to the more frequently seen obturator jerk in M-TURBT than B-TURBT, careful surgical approach is needed during M-TURBT.

Abstract
OBJECTIVE The aim of this study is to evaluate sexual functions and quality life of patients who are followed-up for non-muscle invasive bladder cancer (NMIBC). MATERIAL AND METHODS Between March 2015-June 2016, 50 patients underwent cystoscopy for NMIBC. At the end of the 1st year follow-up patients were assessed for sexual functions using 5-item version of the International Sexual Function Index (IIEF-5) for male and the Female Sexual Function Index(FSFI) for female; for quality of life (QoL) by the European Organisation for Research and Treatment of Cancer-Non-Muscle Invasiv Bladder Cancer Quality of Life Questionnaire (EORTC QLQ-NMIBC24) and for emotional status by Beck depression inventory. RESULTS There were 44 male and 6 female patients with the mean age of 57.6±11.5 years. Twenty patients received intravesical treatment after transurethral resection of bladder tumour. The mean Beck (10.7±9.5) IIEF-5 (15.6±5.9), FSFI (19.2±10.9), and the EORTC-QLQ NMBIC 24 (38.2±7.7) scores of the patients were determined as indicated. Among the patients, 42 (84%) of them were not feeling bad about their bladder tumors and 37 (74%) were not worrying about their daily lives. Moreover, 12 (24%) patients were not interested with sexuality, while 27 (54%) of them did not feel comfortable about sexual sincerity. Interestingly, 27 patients receiving intravesical treatment were concerned that the treatment they received for prevention of recurrence and progression of bladder tumor infect their partners during sexual intercourse. CONCLUSION NMIBC affects patients' sexual functions and QoL negatively. Therefore during the follow-up of these patients, it is important to inform these patients accurately about their treatments to be applied and predicted complications in the follow up period.

Abstract
OBJECTIVES To evaluate the results of synchronous dual implantation of penile (PP) and artificial urinary sphincter prosthesis (AUSP) in patients with severe erectile dysfunction (ED) and urinary incontinence (UI) after radical prostatectomy (RP). METHODS Between January 2006 and March 2015, patients who underwent synchronous dual implantation of PP for severe post-RP ED and AUSP for moderate to severe post-RP UI in our clinic were screened retrospectively. The erectile function and the continence status were evaluated by the questionnaires of IIEF-5 and ICIQ-SF. Results for the preoperative period and for the 1st postoperative year were revealed from patient charts. Long term results were evaluated by telephone interviews. Comorbidities, infection rates and complications were noted. RESULTS A total of 14 patients underwent synchronous dual implantation; out of which, 11 had a long enough follow up period for a sufficient long term evaluation. 3/11 had MPP and 8/11 had two-piece IPP implantation together with an AUSP. All of the implantations were carried out through an upper transverse scrotal incision. Mean follow up time was 61.3 ± 20 months. In 1 patient who had received adjuvant radiotherapy, both of the devices were removed due to infection and cuff erosion. Mean daily usage of pads diminished from 4 to 1 while ICIQ-SF score decreased from 19 to 2 and IIEF-5 score increased from 3 to 23. CONCLUSION Synchronous implantation of PP and AUSP is a safe and effective treatment option for patients with severe ED and moderate to severe UI after RP.

Abstract
We investigated the microscopic structure of transverse sections of the oculomotor, trochlear and abducens nerves of Arabian foals using stereological methods. Bilateral nerve pairs from 2-month-old female Arabian foals were analyzed. The tissues were embedded in plastic blocks, then 1 µm thick sections were cut and stained with osmium tetroxide and methylene blue-azure II. Stereology was performed using light microscopy. Morphometry showed that the right and left pairs of nerves were similar. The transverse sectional areas of the oculomotor, trochlear and abducens nerves were 1.93 ± 0.19 mm2, 0.32 ± 0.06 mm2 and 0.70 ± 0.08 mm2, respectively. The oculomotor nerve exhibited a significantly greater number of myelinated axons (16755 ± 1279) and trochlear (2656 ± 494) and the abducens nerves (4468 ± 447). The ratio of the axon diameter to myelinated nerve fiber diameter was 0.58, 0.55 and 0.55 for the oculomotor, trochlear and abducens nerves, respectively. Of the three nerves studied, the abducens nerve exhibited the greatest nerve fiber area, myelin area, nerve and axon diameters, and myelin thickness. The ratio of small myelinated nerve fibers was greatest in the oculomotor nerve.

Neutrophil to Lymphocyte Ratio as a predictor of early penile prosthesis implant infection. Int Urol Nephrol 2017; 49:947-953. [PMID: 28303443 DOI: 10.1007/s11255-017-1569-z] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2017] [Accepted: 03/08/2017] [Indexed: 12/31/2022]
Abstract
PURPOSE To investigate the predictive value of preoperative serum neutrophil-to-lymphocyte ratio (NLR) on the development of postoperative infections in patients undergoing penile prosthesis implantation (PPI). METHODS We retrospectively analyzed the data of 361 patients who underwent PPI over a 4-year period with at least 1-year follow-up. Demographics, blood results, and postoperative 1-year complications were recorded. Recommended cutoff values of NLR for early postoperative infectious complications were determined using receiver operating characteristic analysis. RESULTS A total of 153 patients with the mean age of 56.4 ± 8 years were included in the study. Mean follow-up time was 56.7 ± 30.4 months (12-108 months). Early postoperative infectious complications were occured in 18 patients (11.8%). These infections were prosthesis infection in 8 patients (5.2%), wound infection in 6 patients (3.9%), and urinary tract infection in 4 patients (2.6%). All these complications were occured within the first year of the surgery. Mean NLR was statistically higher in patients with postoperative complications when compared with uncomplicated cases (7.2 ± 3.9 vs. 2.2 ± 1.4, p < 0.001, respectively) Using a cut point of 6.2, preoperative NLR predicted postoperative complications with a sensitivity of 67% and specificity of 99%. CONCLUSIONS This study is the first to investigate the relationship between NLR and early postoperative infection as a complication of PPI. The results demonstrated that the NLR value could be a potential laboratory parameter for predicting early postoperative infectious complications in patients undergoing PPI.

Abstract
OBJECTIVE We updated our data on penile fractures and investigated the significance of the time interval from the incident of the fracture until the operation on the erectile functions and long-term complications. MATERIAL AND METHODS Between January 2001 and June 2014, 64 patients were operated on with a preoperative diagnosis of penile fracture. We could evaluate 54 of these patients. The patients were classified into 3 groups according to the time interval from the time of fracture until surgery. The validated Turkish version of the erectile components of International Index of Erectile Function (IIEF) was answered by every patient 3 times after the surgery; before the incident of fracture, at first postoperative year, and at the time of the study (IIEF-5 and question #15 were used). The complications were noted and an erectile function index score was calculated for every patient. RESULTS Mean follow up period was 44.9 (±2.8) months for all patients There was no statistically significant difference between the 3 groups in terms of the erectile components of IIEF questionnaire scores for the time periods and for individual patients in each separate group. Complications for all groups were also similar. CONCLUSION In consideration of long-term results, neither serious deformities nor erectile dysfunction occur as a consequence of a delay in surgery performed within the first 24 hours in patients without urethral involvement.

Abstract
OBJECTIVE We investigated the prognostic value of preoperative neutrophil-to-lymphocyte ratio (NLR) on germ cell testicular tumors (GCT). MATERIAL AND METHODS The data of 53 patients who underwent inguinal orchiectomy were analyzed retrospectively. NLR was calculated from the preoperative complete blood cell counts. Receiver operating characteristic (ROC) analysis was performed to find the threshold values for NLR. Correlations between cancer-specific survival (CSS) and progression-free survival (PFS) and NLR were evaluated. RESULTS The mean follow-up time was 23.55±18.06 months. The mean level of NLR was 3.08±1.81. Optimal threshold values of NLR was calculated as 3.55 for PFS (area under curve, AUC: 0.55) and 3.0 for CSS (AUC: 0.66). For patients with a NLR of <3.55 and NLR of ≥3.55, mean times-to-progression were 55.71 months (95% CI, 51.27-60.14) and 51.95 months (95% CI, 38.02-65.87, p=0.152), respectively. As well as, for patients with a NLR of <3.0 and NLR of ≥3.0, mean times-to-cancer specific death were 54.72 months (95% CI, 49.05-60.38) and 49.43 months (95% CI, 37.64-61.22, p=0.119), respectively. CONCLUSION Preoperative NLR is not a useful tool to predict the prognosis of patients with GCT.

Abstract
OBJECTIVES In this study we compared neutrophil-to-lymphocyte ratio (NLR) and neutrophilto- monocyte ratio(NMR) between patients with prostate cancer after first transrectal ultrasound (TRUS)- guided biopsy and patients with benign prostate hyperplasia(BPH) after second TRUS-guided biyopsy. METHODS A total of 224 patients who underwent multi (≥12)-core TRUS -guided biopsy at our clinic for elevated PSA or abnormal digital rectal examination in between January 2008 and March 2015 were retrospectively analyzed. There were 2 groups. Group 1 consisted of 146 patients with a diagnosis of prostate cancer after the first TRUSguided biyopsy and group 2 consisted of 78 patients with a diagnosis of benign prostate hyperplasia after second TRUS-guided biyopsy. Age, PSA, NLR and NMR values were compared between the two groups. RESULTS There were no statistically significant correlation between PSA and NLR(p=0.46). The mean of age, PSA, NLR, NMR values in the group 1 and 2 were respectively 64.6±7.7 and 61.6±6.9, 6.5±1.9 and 5.3±1.2, 2.8±1.5 and 2.3±1.1, 9.2±3.9, 8.1±2.9 (p=0.03, p=0.001, p=0.012 and p=0.30). The mean PSA, NLR ,NMR values of the group 1 were significantly higher than those in group 2 (p=0.002). Gleason grade and pathological stage were significantly increases as NLR increases. CONCLUSION NLR and NMR in patients with BPH after second TRUS-guided biopsy were lower than that of those with a diagnosis of prostate cancer after the first TRUS-guided biopsy.White blood test subtypes can be considered for the decision to perform a second TRUSguided biopsy in patients with previous negative biopsy with persistently elevated PSA.

Abstract
Telemedicine is the use of medical information exchanged from one site to another via electronic communications to improve a patient's clinical health status. Telemedicine includes a growing variety of applications and services using two-way video, email, smart phones, wireless tools and other forms of telecommunications technology. Starting out over forty years ago with demonstrations of hospitals extending care to patients in remote areas, the use of telemedicine has spread rapidly and is now becoming integrated into the ongoing operations of hospitals, specialty departments, home health agencies, private physician offices as well as consumer's homes and workplaces. There's also a current trend in the use of telemedicine in urology. In the present paper we aimed to review the recent literature about telemedicine and the use of telerounding and telementoring in urological procedures.

Abstract
OBJECTIVES To compare perioperative outcomes and complications of plasmakinetic bipolar and monopolar transurethral resection of bladder tumors (TURBT) in patients with non-muscle invasive bladder cancer (NMIBC). METHODS Between March and December 2015, a total of 130 consecutive patients underwent TURBT for NMIBC. Patients were equally randomized into monopolar TURBT (M-TURBT) and bipolar TURBT (B-TURBT) groups. Primary outcome of this study was safety of the procedures including obturator jerk, bladder perforation, clot retention, febrile urinary tract infection and TUR syndrome. The secondary outcome was efficacy of both TURBT procedures, including complete tumor resection, sampling of the deep muscle tissue and sampling of the qualified tissues that without any thermal damage. RESULTS Complete tumor resection rate was higher in B-TURBT than M-TURBT (89.2% vs 78.5%, respectively), but the difference was not significant (p=0.152). No significant differences were found between the muscle tissue sampling rates (64.6% vs 72.3%, p=0.345) and the numbers of patients with thermal tissue damage (7 patients vs 3 patients, p=0.194). Obturator jerk was detected in 21.5% of the patients in M-TURBT group and 4.6% of the patients in B-TURBT group, and this difference was statistically significant (p=0.013). Bladder perforation was significantly higher in M-TURBT group than B-TURBT (21.5 % vs 6.1%, p=0.039). CONCLUSIONS Bipolar TURBT had significantly lower obturator jerk and bladder perforation than monopolar. B- TURBT is a reasonable treatment modality in patients with NMIBC.

Abstract
INTRODUCTION We aimed to demonstrate the efficacy, safety, and convenient use of fosfomycin trometamol in the preoperative antibiotic prophylaxis (PAP) of transrectal ultrasound-guided biopsy of the prostate (TRUSBP) in this prospective, randomized study. METHODS Between May 2014 and May 2015, a total of 300 patients who underwent TRUSBP were examined prospectively. Patients were randomized into two groups: group 1 consisted of 150 patients who were administered a single dose of 3 g oral fosfomycin as a PAP the night before the procedure; group 2 consisted of 150 patients who were administered 500 mg oral ciprofloxacin 60 min before the procedure as a PAP. Post-procedural febrile and afebrile infectious complications and pathological characteristics of the two groups were compared prospectively. RESULTS The mean age of the patients was 63.5±0.6 years in group 1 and 62.9±0.6 years in group 2. A total of two patients (1.3%) in group 1 and nine patients (6.0%) in group 2 experienced afebrile urinary tract infection (UTI). Afebrile UTI rate was significantly higher in group 2 (1.3% s. 6.0%, p=0,032). Febrile UTI was detected in two patients in group 2 and one patient in group 1. Urine cultures revealed 35.7% fluoroquinolone resistance. As a limitation, although the sample size was appropriate due to the power calculation, we believe that comprehensive studies including larger patient cohorts are needed to support our findings. CONCLUSIONS Due to its ease-of-use with only a single dose and lower rates of infectious complications (resistant and febrile UTIs), fosfomycin trometamol is a strong alternative for antibiotic prophylaxis in TRUSBP.

Abstract
INTRODUCTION In this prospective randomized controlled study, we investigated the efficacy of obturator nerve block (ONB) on adductor muscle spasm and related short-term outcomes and complications in patients who underwent transurethral resection of lateral wall-located bladder tumours (TURBT). METHODS Between July 2014 and February 2015, 70 patients scheduled to undergo TUR of lateral bladder wall tumours were enrolled in the study. All patients were preoperatively evaluated by cystoscopy and imaging tools and selected according to localized tumours on the lateral bladder wall. Patients were randomly allocated to Group SA (35 patients who underwent only spinal anesthesia) and Group ONB (35 patients who underwent spinal anesthesia combined with ONB by the nerve stimulator). An independent observer, blinded to the approach, evaluated the obturator signs, including adductor muscle contraction, bladder perforation, and completeness of the resection during the TURBT procedure. RESULTS The differences between groups regarding mean operation time, tumour size, and number were not statistically significant (p > 0.05). Adductor muscle contraction was detected in 40% of patients in Group SA and 11.4% in Group ONB. This difference was statistically significant (p = 0.021). Complete bladder perforation was detected in 2 patients in Group SA, whereas no perforation was observed in Group ONB. There was no case of severe bleeding in both groups. CONCLUSIONS We found that ONB performed after spinal anesthesia was effective in preventing intraoperative complications due to adductor muscle spasm while performing TURBT. Our study limitations include its small sample size, since we only enrolled patients with primary lateral wall-localized bladder tumour. Also, we excluded patients who underwent bipolar TURBT.

Abstract
BACKGROUND/AIM To evaluate the effects of the storage/total International Prostate Symptom Score (s/T) ratio on the selection and success of medical therapy in men with lower urinary tract symptoms (LUTS). MATERIALS AND METHODS A total of 54 men (>45 years of age) with moderate or severe LUTS were divided into 2 groups according to the s/T ratio: Group 1 at <0.43 and Group 2 at >0.43. Tamsulosin (0.4 mg to Group 1) and tolterodine ER (4 mg to Group 2) were administered. Patients were evaluated during the 1st and 3rd months of follow-up treatment. RESULTS Thirty-seven (68.5%) and 17 (31.5%) patients were in Groups 1 and 2, respectively. The mean s/T ratios in Groups 1 and 2 increased to 0.38 ± 0.19 from 0.33 ± 0.08 (P = 0.03) and decreased to 0.54 ± 0.18 from 0.59 ± 0.1 (P = 0.17) during the 3rd month of follow-up, respectively. The treatment success rates of Groups 1 and 2 were 88.4% and 75.7%, respectively. Nine unsuccessful cases were treated with combination therapy and the treatment success was 86.6% at follow-up. CONCLUSION The s/T ratio is effective to determine symptom dominance in men with LUTS and can guide medical treatment selection through better identification of symptoms.

Abstract
Purpose Urinary incontinence is one of the major urinary symptoms in children and adolescents and can lead to major distress for the affected children and their parents. In accordance with the definitions of the Standardization Committee of the International Children's Continence Society, daytime urinary incontinence (DUI) is uncontrollable leakage of urine during the day. The aim of this cross-sectional study was to investigate the prevalence and associated risk factors of DUI in Turkish primary school children. Materials and Methods The questionnaire, which covered sociodemographic variables and the voiding habits of the children, was completed by the parents of 2,353 children who were attending primary school in Denizli, a developing city of Turkey. The children's voiding habits were evaluated by use of the Dysfunctional Voiding and Incontinence Symptoms Score, which is a validated questionnaire. Children with a history of neurological or urological diseases were excluded. Results The participation rate was 91.9% (2,164 people). The overall prevalence of DUI was 8.0%. The incidence of DUI tended to decrease with increasing age and was not significantly different between genders (boys, 8.8%; girls, 7.3%; p=0.062). Age, maternal education level, family history of daytime wetting, settlement (urban/rural), history of constipation, urinary tract infection, and urgency were independent risk factors of DUI. Conclusions Our findings showed that DUI is a common health problem in primary school children. In an effort to increase awareness of children's voiding problems and the risk factors for urinary dysfunction in the population, educational programs and larger school-based screening should be carried out, especially in regions with low socioeconomic status.

Abstract
This article describes the scanning electron microscopic (SEM) features of the ovine interdigital sinus. The lumen was filled with a dense secretory material and quite a number of hairs embedded in the luminal content. For SEM purposes, the sinus was divided into three parts: base, body and neck. At the cut surface, the wall exhibited significant folds which were almost absent in the base, the very short blind end of the sinus. The wall had three layers: epidermis, dermis and fibrous capsule. Stratified epithelium with a prominent keratin layer faced the lumen. The inner surface was similar to the skin surface; however, it was coarser due to folds. The fibrous capsule was composed mainly of dense connective tissue, constituting the outermost layer of the wall. The dermis contained common skin structures including sebaceous glands, hair follicles, arrector pili muscles and apocrine glands. Sebaceous glands appeared as groups of bubbles if they were not collapsed. Apocrine glands generally appeared as a group of coiled tubules. They frequently exhibited apocrine blebs, which is a feature of apocrine secretion. SEM was able to locate some secretory vesicles in the lumen of apocrine tubules which is frequently filled by secretory content. Thus, the apocrine tubules exhibited classical features of apocrine secretion.

Abstract
Arterial vascularisation of the ovine pineal gland was investigated by latex injection preparations of the common carotid artery in 20 adult Akkaraman sheep brains under stereo light microscope. It was observed that the arterial supply comes exclusively from branches of the caudal cerebral artery. The pineal gland was found to contain a rich vascular network. This network also received a few branches from the caudal choroid rami.
