Comparison of Perioperative Outcomes and Urethral Complications Between Using 24-French and 26-French Resectoscope Sheaths in Holmium Laser Enucleation of the Prostate
(Galenos Publishing House, 2022) Yildiz,A.; Akdemir,S.; Anil,H.; Guzel,A.; Arslan,M.
Aim: Although the 26F resectoscope is frequently used in transurethral prostatectomy, there are some concerns with high-caliber shafts. We compared 24F and 26F resectoscope used for Holmium Laser Enucleation of the Prostate (HoLEP) in terms of effects on postoperative urethral complications and perioperative outcomes. Methods: Data from patients undergoing HoLEP from 2017 to 2021 was retrospectively analyzed. All surgeries were completed by a single surgeon. The patients were divided into one of two groups according to the resectoscope diameter (24F or 26F). All patients were followed up for urethral complications for 12 months. Perioperative outcomes and urethral complications were compared between the groups. Results: The study included 301 patients. The mean age of patients was 68.5±8.3 and 69.1±8.6 for the 26F group (n=180) and the 24F group (n=121), respectively (p=0.608). A total of seven in the 26F group (3.8%) and 3 patients in the 24F group (2.4%) had postoperative urethral stricture (US) (p=0.503). Besides, 2 patients (26F) and 1 patient (24F) had postoperative bladder neck contracture (BNC) (p=0.807). The operation efficiency was 1.25 g/min in the 26F group and 1.17 g/min in the 24F group (p=0.005). Conclusion: The use of 24F or 26F RS was not shown to cause statistically significant differences in the incidence of US and BNC during the 12-month follow-up. The use of the 24F RS significantly reduces surgical and morcellation efficiency. © 2022 by The Medical Bulletin of Istanbul Haseki Training and Research Hospital The Medical Bulletin of Haseki published by Galenos Yayinevi.

Does transition from standard to Retzius-sparing technique in robot-assisted radical prostatectomy affect the functional and oncological outcomes?
(Page Press Publications, 2021) Anil,H.; Karamik,K.; Yildiz,A.; Savaş,M.
Objective: To appraise the outcomes on the Retzius-sparing robot-assisted radical prostatectomy (Rs-RARP) learning curve of a surgeon with previous experience of anterior (standard) RARP. Materials and methods: The first 50 cases during the Rs-RARP learning curve (group 1) and 50 cases after the second 100 cases with the standard approach (group 2) were comprised in the study. Patients who used zero or one safety pads were considered continent. Erectile function recuperation was characterized as the competence to achieve penetrative intercourse without receiving any medication. All patients were reevaluated at two weeks, first, third, sixth, and 12th months after surgery using IIEF-5, PSA level, and continence status. Results: Immediate continence rates following catheter removal were 32/50 (64%) in Rs-RARP group and 26/50 (52%) in S-RARP group (p = 0.224). The continence recovery rate was 48/50 (96%) in Rs-RARP group and 46/50 (92%) in the S-RARP group at 12 months follow-up (p = 0.400). Total nerve-sparing surgery was enforced in 36/50 (72%) patients for group 1 and 35/50 (70%) patients for group 2. Potency recovery was 27/43 (62.8%) in Rs-RARP and 30/44 (68.2%) for S-RARP at 12 months follow up (p = 0.597). Surgical margin positivity was detected in 6/50 (12%) cases in the Rs-RARP group and in 4/50 (8%) cases in the S-RARP (p = 0.444). Conclusions: Functional and oncological results are not negatively affected in the first 50 cases for a surgeon who is experienced in S-RARP before transition to the Rs-RARP method. © 2021 Edizioni Scripta Manent s.n.c..

Extraperitoneal Laparoscopic Versus Transperitoneal Robot-Assisted Laparoscopic Approaches for Extended Pelvic Lymph Node Dissection During Radical Prostatectomy
(Mary Ann Liebert Inc., 2022) Yildiz,A.; Anil,H.; Akdemir,S.; Aksaray,E.E.; Ateş,M.; Arslan,M.
Background: We aim to directly compare the feasibility and safety of extended pelvic lymph node dissection (PLND) during transperitoneal robotic-assisted radical prostatectomy (Tp-RARP) and extraperitoneal laparoscopic radical prostatectomy (Ep-LRP). Materials and Methods: We retrospectively identified the prospectively maintained database records of 162 patients diagnosed with prostate cancer (PC) who underwent Ep-LRP or Tp-RARP with extended PLND. Patients with risk of nodal metastases over 5% according to Briganti nomogram received extended PLND. All data analyzed in this study were based on the documentation in our PC database including age, body mass index, Charlson comorbidity index score, preoperative prostate-specific antigen, history of abdominal surgery, biopsy Gleason score, total operation time, postoperative pelvic drainage time, pathological results, lymph node yield (LNY), percentage lymph node involvement (%LNI), and perioperative complications. Patients were followed up for biochemical recurrence in the postoperative period. Results: Eighty-two of the 162 enrolled patients were in group 1 (Ep-LRP+PLND) and 80 were in group 2 (Tp-RARP+PLND). There were no statistically significant differences between the groups regarding preoperative demographics and clinical characteristics. The median LNY was 17 (range 8-27) and 17.5 (range 10-29) in groups 1 and 2, respectively, and no statistically significant difference was found. There was no significant difference between the groups in terms of biochemical recurrence-free survival with mean follow-up of 44.8 months after radical surgery. Conclusion: Our results support the view that extended PLND through the Ep-LRP approach is a feasible and safe procedure without compromising oncological efficacy compared with a similar template attempted during Tp-RARP.

Investigating the usage possibility of metal mono carboxylates(metal naphthenates) as antibacterial agent in textile applications
(Inst. Nat. Cercetare-Dezvoltare Text. Pielarie, 2014) Yildiz,A.; Öztaş,M.; Dumrul,G.; Yeşilyurt,M.; Atav,R.; Aǧirgan,A.Ö.; Kaya,A.D.
In this study, it was aimed to produce a substance, which could be used as an antibacterial agent in textiles, from petroleum sub-products in order to extend the use of petroleum and petroleum sub-products in textiles. For this aim, complex compounds with copper, cobalt, nickel, zinc, and sodium, were produced. Then, those compounds were applied onto cotton fabric by padding process, and their antibacterial activities were evaluated according to the AATCC 147 agar diffusion test method. As a result of the trials, it was determined that best results were obtained against both gram-positive and gram-negative bacteria with copper mono carboxylate. Its activity was still present against Staphylococcus aureus and Escherichia coli after 3 washings and against Bacillus subtilis and Klebsiella pneumoniae after 10 washings.
