Introduction and Objectives: A comparative study of standard radical cystectomy and prostate capsule sparing radical cystectomy regarding functional and oncological outcomes. Materials and Methods: A randomized study of 96 patients with transitional cell carcinoma of the bladder (December 2014 - June 2016) was done. We excluded cases with preoperative T4 staging, lymphadenopathy, prostatic specific antigen > 4 ng/dl, and cases with positive biopsies from the bladder neck, trigone, and/or prostatic urethra. Patients were divided into 2 groups, Group 1: standard radical cystectomy with orthotopic diversion (n = 51), Group 2: prostate capsule sparing cystectomy with orthotopic diversion (n = 45). Preoperative transrectal ultrasound and prostatic biopsies were done in Group 2 to exclude prostate cancer. We compared the urinary continence and erectile function in both groups after 6 months, 1, and 2 years. Results: There was no significant difference between the groups regarding preoperative demographic data, tumor stage, grade, site by cystoscopy, and biopsy. Intraoperative monitoring showed no significant differences regarding blood loss, surgical complications, or operative time (2.5 ± 0.48 vs. 2.4 ± 0.45 h). There was a significantly higher percentage of continence and potency in Group 2 than in Group 1. Sixteen cases (35.6%) in Group 2 but only 4 cases (7.8%) in Group 1 developed large post-voiding residual urine and needed intermittent self-catheterization cleaning (p = 0.001). The tumor recurrence rate was not significantly different between the groups after 2 years (p = 0.3). Conclusion: Prostate capsule sparing cystectomy is a good option in selected cases with better continence and potency and without compromising oncological outcomes after 2 years.

Aim: To compare surgical parameters and visual outcomes of coaxial microincision cataract surgery (MICS) with standard phacoemulsification. Methods: A prospective randomized study was conducted on 60 eyes of 60 patients with age-related uncomplicated cataract who underwent: standard phacoemulsification surgery (30 eyes) i.e., Group 1, or coaxial MICS (30 eyes) i.e., Group 2. Intraoperative parameters were mean effective phacoemulsification power (EPP), effective phacoemulsification time (EPT), and total volume of balanced salt solution (BSS) used. Best-corrected visual acuity (BCVA) and surgically induced astigmatism (SIA) were evaluated pre- and postoperatively. Results: Mean BCVA at 6 weeks was 0.04 ± 0.07 in Group 1 and 0.05 ± 0.08 in Group 2. No significant difference was observed in SIA between the two groups. Mean EPT was 29.80 ± 3.67 seconds in Group 1 and 31.93 ± 4.08 seconds in Group 2. The mean total EPP in Group 1 was 35.77 ± 5.17%, whereas it was 33.70 ± 3.05% in Group 2. There was a significant statistical difference between mean EPP and EPT in the two groups. Mean total BSS volume used in Group 1 was 128.83 ± 19.81 ml, whereas it was 139.33 ± 13.57 ml in Group 2. Conclusion: Although EPT and BSS volume used were significantly higher in coaxial MICS, the postoperative results of the two techniques were comparable.

289 Background: Salvage radiotherapy (SRT) may be employed as a potentially curative intervention for patients experiencing biochemical failure (serum prostate-specific antigen [PSA] ≥ 0.2 ng/mL) after prostatectomy for localized prostate cancer. Patients not showing a favorable response to SRT alone may require additional therapies and may benefit from earlier identification of this need. Methods: 131 consecutive patients received SRT during the timeframe of this study. 76 were deemed eligible based on the following criteria: prostatic adenocarcinoma diagnosis receiving SRT, no clinical evidence of metastasis, no hormone use prior to/during SRT, serum PSA measurement halfway through SRT, and minimum follow-up time of 3 months. Median follow-up time was 51.6 months. Eligible patients were divided into three groups based on PSA response by the midpoint of treatment: no change, decrease, or increase in PSA. The primary endpoint of the study was clinical failure (measured from SRT completion), defined as serum PSA value ≥0.2ng/mL above the post-radiotherapy nadir, initiation of androgen deprivation therapy, development of bone metastasis, or death from prostate cancer. Results: 13.1% experienced no change in PSA halfway through SRT (group 0), 68.4% of patients experienced a decrease (group 1), 18.4% experienced an increase (group 2). Four-year freedom from clinical failure was 60.0% for group 0, 58.3% for group 1, and 41.7% for group 2. Median time to clinical failure was 71.7 months for group 1, 26.8 months for group 2, and was not reached for group 0. Pairwise multiple comparison demonstrated a significant difference in four-year freedom from clinical failure between groups 1 and 2 (p = 0.036). Conclusions: These data strongly suggest that changes in PSA are apparent midway through SRT and are associated with 4-year freedom from clinical failure. Further study is warranted to determine whether mid-treatment PSA during SRT may be used to identify a subset of patients that may benefit from treatment intensification.

Introduction: The purpose of this study was to evaluate and compare complications after radical cystectomy in patients aged ≥75 years. Materials and Methods: 251 patients aged 75-95 years (median 79) underwent radical cystectomy between 2000 and 2012 at four institutions. The patients were divided into two groups: ≥75-84 years of age (group 1) versus ≥85 years of age (group 2). Comorbidities, body mass index, and complications were obtained retrospectively, except at the Central Hospital of Bolzano and Weill Cornell Medical Center, which collected data prospectively. Cancer-specific survival, overall mortality, hospital stay, clinical outcome and complications were assessed. Complications were categorized using the Clavien-Dindo classification reporting system. The mean follow-up was 21 months. Results: The median hospital stay was 17 (2-91) days. Perioperative Clavien-Dindo grade ≥III complications were seen in 24.1% (48/199) of group 1 patients and 19.2% (10/52) of group 2 patients (p = 0.045). 30- and 90-day mortality was 4.5 and 13.5% in group 1 and 6.5 and 32.3% in group 2, respectively. Only the 90-day mortality rate was statistically significant (p < 0.05) between the two groups. The 3-year overall survival was 40% in group 1 and 34% in group 2. The 3-year cancer-specific survival was 52% in group 1 and 50% in group 2. Conclusions: We evaluated a large series of elderly (≥75 years) patients undergoing radical cystectomy at four institutions. Comparing patients aged ≥75-84 and ≥85 years revealed no significant difference in complications, 30-day mortality, overall and cancer-specific survival rates. Only 90-day mortality rates were significantly higher in the ≥85-year-old patients.

Background: To compare the peri-operative complications, related to radical cystectomy and to compare peri operative outcomes between patients receiving neoadjuvant chemotherapy and those treated with radical cystectomy alone.Methods: This was prospective observational study. The study was conducted at ‘The Department of Urosurgery, R. G. Kar Medical College and Hospital, Kolkata’. Study period was between March 2016 to March 2018. Total 36 patients were included in present study. Patients after clinical diagnosis and risk factor profile analysis were divided into two groups: (1) radical cystectomy alone (n=24) (2) patients received neoadjuvant chemotherapy (gemcitabine and cisplatin regime) followed by radical cystectomy (n=12). Different parameters were compared.Results: Total 36 patients were underwent radical cystectomy. In group 1, 96% (n=23) were having T2 stage while 4% (n=1) were having T3stage. In group 2 25% (n=3) patients were having T2stage while 75% (n=9) were having T3 stage as per CECT staging. There were no significant difference noted in perioperative complications in both groups except perioperative adhesions (group 2, 47% vs group 1, 8.3%). There was significant time delay in radical cystectomy in group 2 (patients received neoadjuvant chemotherapy).Conclusions: We found there were no significant increase in perioperative morbidity and mortality with Neoadjuvant Chemotherapy. Most of the complications were comparable to previous studies.

e16059 Background: To compare the oncological outcomes of laparoscopic versus open surgery in radical cystectomy for bladder cancer. Methods: A prospective non-randomized study was conducted between January 2003 and November 2008 in 52 patients, 2 women and 50 men, who underwent radical cystectomy for bladder cancer. Thirty seven cystectomies were carried out by laparoscopic surgery (LS) and 15 by open surgery (OS). Mean patient age was 67.3 ± 9.7 years. The median preoperative ASA score was 2 (1–3) in both groups. Kaplan-Meier curves were constructed to estimate the survival rate for the whole sample. Datas were compared by Log-rank test. Current followup, overall and specific deaths were used as endpoints. The survival time was defined as the time elapsed from the date of radical cystectomy to the endpoint. Results: All tumours were transitional cell carcinoma, high-grade and stage < pT3b pN0. One patient of OS group had a positive surgical margin. Eight patients (15.4%), 7 of LS group and 1 of OS group, completed 5 years of follow-up. At the last follow-up 40 patients (76.9%) were alive with no evidence of disease and 5 (9.6%) died, two patients (3.8%) from metastasis and 3 (5.7%) from different causes. No patient developed port- site metastasis. Overall survival was significantly better in LS group than in the OS group (p=0.039). No statistical difference was noted for Specific survival. Mean patient follow-up was 30.9 ± 20.3 months. Conclusions: The data suggest that LRC provides oncological outcomes comparable to contemporary series of open RC. No significant financial relationships to disclose.

e15721 Background: Recent studies indicate that pancreatic cancer stem cells (CSC) may predict disease behavior and survival outcomes of pancreatic ductal adenocarcinomas (PDACs) patients (pts). Several CSC markers have been reported in PDAC (Fitzgerald, TL, 2014). We herein evaluated the impact of CSC markers including CD44 and Epithelial Specific Antigen (ESA) on survival outcome of PDAC pts who had liver or lung metastasis after initial surgical resection (IR). Methods: Clinicopathologic features and survival of 59 PDACs were analyzed. Pts with IRB approval, and whom had available primary tumor tissue, were included. All neoplasms were immuno labeled with CD44 and ESA. Staining intensity was scored as weak (1), moderate (2), strong (3), while the staining pattern was scored as: few (1), patchy (2), and diffuse (3). The expression for CD44 and ESA was accepted positive if total score ≥4. Time from relapse to death (TRD) was estimated using the Kaplan-Meier method censoring patients that were alive at the last follow up. Survival curves were compared using the log-rank test Results: Of 59 pts, 42 (71 %) had liver, 10 (17%) had lung and 7 (12%) had both liver and lung metastasis. M/F = 34/25; mean age = 64.2 (range, 34-90). Patients were subcategorized as follows; thirteen cases were CD44 (+)/ESA (-) (group1) and 13 were CD44 (-)/ESA (+) (group 2). Eight (61.5%) of group 1 tumors and 2 (15.3%) of group 2 were poorly differentiated. At last follow-up, except one with 63 months survival, all pts died of disease with 23.3 months (range, 3-67) median OS. No significant difference in TRD was observed between group 1 (6.9 months) and 2 (13.8 months) (p = 0.62). However, we observed group 1 tumors had worse OS (12 months) compared to group 2 (36 months). Conclusions:A worse outcome trend was observed for pts with CD44 (+)/ESA (-), albeit not statistically significant and likely limited by small numbers. Further studies are warranted to evaluate the robustness of this observation.

Clinical Relevance Charcoal based-powders are not effective for dental bleaching. SUMMARY Charcoal-based dentifrices for dental whitening are a novelty in the market. Manufacturers claim that such charcoal-based products have whitening, remineralization, antimicrobial, and antifungal properties of charcoal in such products. However, there is no substantial scientific evidence for these claims. This laboratory randomized study was designed to evaluate the whitening properties of a charcoal-based toothpowder. A total of 45 bovine dental enamel discs were randomly distributed into three groups (n=15): group 1, mechanical brushing with a 1450-ppm F toothpaste (control group); group 2, mechanical brushing with an activated charcoal-based powder; group 3, bleaching per the standard protocol using 10% carbamide peroxide. The surface roughness and color of each specimen were analyzed at baseline and after 14 days of experiment. The surface of one randomly selected specimen from each group was examined using a scanning electron microscope (SEM). The Kruskal-Wallis test was used to compare groups at a significance level of 5%. Only group 3 promoted a statistically significant effect on ΔE compared with groups 1 and 2 (p&lt;0.001 and p=0.003, respectively). No statistically significant difference was found between groups for surface roughness (p&gt;0.05). SEM revealed a more irregular surface in group 1 specimens compared with group 2 and 3 specimens. The charcoal-based powder did not seem to have any bleaching effect.

Background There are opinions that telangiectasis and reticular veins are asymptomatic and constitute a cosmetic problem only. However, it has been proven that telangiectasis and reticular veins also affect the quality of life and are symptomatic. Methods Ninety consecutive female patients who were admitted to our outpatient clinic and did not have insufficiency in deep, superficial and perforating veins were included in this study. All participants were divided into three groups as the compression group (Group 1), medical treatment group (Group 2), and sclerotherapy group (Group 3). The initial complaint severities of all patients were noted. Except for patient compliance assessment, baseline, 1st month (T1), 3rd month (T2) and 6th month (T3) evaluation records were kept in all three groups. Results The study began with a total of 90 patients, 30 patients in each group. The mean ages of Groups 1, 2 and 3 were 39.73 ± 8.51 years, 39.30 ± 8.67 years, and 40.77 ± 9.45 years, respectively. The rates of decrease in pain, itching, restless leg, and muscle cramps were similar among the patient groups at all times (P > 0.05). The rate of reduction in swelling was similar between the groups at T1 and T2 (P > 0.05), while there was a significant difference between the groups at T3 (P = 0.009). The groups significantly differed in terms of appearance concern at all times (P = 0.002 for T1, P < 0.001 for T2 and T3). Conclusion We showed that symptoms such as swelling and heaviness in leg can be improved with medical treatment, but the patient's cosmetic satisfaction can increase with sclerotherapy.

Abstract Background In this study, we investigated the effect of preoperative prostate morphology, especially intravesical prostatic protrusion (IPP), on continence after robot-assisted radical prostatectomy (RARP). Methods Retrospective analysis was applied to patients who underwent RARP between October 2010 and July 2014. The following parameters were assessed in all patients: age, body mass index (BMI), prostate-specific antigen, magnetic resonance imaging and pressure-flow studies findings. The impact of preoperative and intraoperative factors on postoperative urinary incontinence (UI) was assessed using multivariate logistic regression analysis. To evaluate the effects of IPP, the patients were divided into groups according to the IPP length: Group 1, < 5 mm and Group 2, ≥ 5 mm. The International Prostate Symptom Score (IPSS), Overactive Bladder Symptom Score, Quality of Life index and the number of pads used were assessed. Results A total of 119 patients were eligible for this study. Multivariate analyses showed that IPP (odds ratio (OR) 1.14, 95% confidence interval (CI) 1.02–1.28, p < 0.05) and nerve-sparing (NS) (OR 0.23, 95% CI 0.18–0.61, p < 0.01) were significant factors related to UI in the first month after RARP. Twelve months after RARP, multivariate analyses revealed that only NS is a factor related to postoperative UI (OR 0.23, 95% CI 0.18–0.61, p < 0.01). The comparison of Groups 1 and 2 indicated significant differences in age (p < 0.01), prostate volume (p < 0.01), total IPSS and voiding symptom score (p < 0.05), compliance (p < 0.01), and detrusor pressure at maximum flow (p < 0.01). Group 1 had a higher continence rate (38.0%) than Group 2 (20.8%) in the first month after RARP (p < 0.05), but the difference was no longer significant from the third month after RARP. The total IPSS and voiding symptom scores were significantly different between the two groups before RARP, however, the significant difference disappeared from the first month after RARP. Conclusions The data suggest that IPP affects early postoperative UI. Although NS was strongly involved in UI in the early and later stages after RARP, IPP had no effect on UI in the later stages.

Introduction and Objective: Transrectal ultrasound guided prostate biopsy (TRUS-Bx) is the definitive step in the diagnosis of prostate cancer (CaP). Patients (pts) generally experience significant pain during the procedure at the point that biopsy should be accompanied by some form of anesthesia. Several different factors influence pain perception (PP) during TRUS-Bx. In our study we want to assess that the use of an ergonomic smaller sized probe reduces PP during the procedure independently from the administration of local anesthesia or pain relieving drugs. Materials and Methods: This was a prospective, randomized study in which 114 pts who underwent TRUS-Bx due to abnormal PSA and/or to digital rectal examination (DRE) suspicious findings were considered eligible. Pts were split in two TRUS-Bx groups into which we used two different sized ultrasound probes. In group 1, 61 pts underwent TRUS-Bx with ALOKA end fire probe (size 74 mm). In group 2, 53 pts underwent TRUS-Bx with B-K Type 8818 probe (size 58 mm). Both groups were treated with no local anesthesia or pain relieving drugs. Pain was evaluated three times using a 10-point visual analogue scale (VAS), during the DRE (VAS 1), during the insertion of the probe (VAS 2) and during the needle piercing (VAS 3). Results: Mean age of pts was 68.03 (SD 8.51); mean tPSA and mean prostate volume was 7.75 (SD 4.83) and 45.17cc (SD 17.7), respectively. The two groups were homogeneous respect to tPSA (p = 0.675) and to prostate volume (p = 0.296); age was significantly different (p = 0.04) between Group 1 (65.93) and Group 2 (70.43), whereas no statistically significant correlation between VAS 3 and age was observed (p = 0.179). Analyzing pain perception, we found no statistically significant difference between the two groups in DRE (VAS 1; p = 0.839); on the contrary, patients in Group 1 experienced on average more pain than other in Group 2 both during the insertion of the probe (VAS 2 3.49 vs 1.09; p &lt; 0.001) and during the needle piercing VAS 3 (2.8 vs 2.00; p &lt; 0.05). The discomfort during probe insertion and manipulation was perceived as very high (VAS 2 &gt; 5) in 42.6% of patients in Group 1 and in 9.4% in Group 2. Globally, the procedure was well tolerated (mean VAS score &lt; 3) in 77% of patients in Group 1 and in 90% in Group 2. The proportion of patients who experienced more than moderate pain (VAS &gt; 5) during needle piercing ranged 24.6 % in Group 1 to 18.9 % in Group 2. Conclusions: Patients who underwent a TRUS-Bx with the 58-mm circumference probe were found to experience lower degree of pain not only during the insertion of the probe through the anal sphincter, but also in the moment of needle piercing.
