Öğe Does the type of the peyronie's curvature effect penile vascular parameters in normopotent men?(Taylor & Francis Inc, 2005) Metin, Ahmet; Kayıgil, Önder; Atmaca, Ali Fuat; Ahmed, Seyit İfteharThe aim of this study is to assess whether the type of penile curvature in normopotent men with Peyronie's disease affects the penil vascular doppler ultrasound parameters, Eifly-three normopotent patients within the stabilization phase of Peyronie's disease were evaluated retrospectively by means of color doppler ultrasonography. Bilateral cavernosal artery diameters before and after intracavernous papaverine injections, peak systolic and end diastolic velocities and the amount of leakage in the deep dorsal penile vein were compared in dorsal and ventral curvature groups of Peyronie's disease. 61% of the patients in dorsal and 59% in ventral Peyronie's curvature group have normal ultrasonographic penile vascular system. 35% and 3.3% in dorsal curvature group and 36.4% and 4.5% in ventral curvature group have venoocclusive dysfunction and mixed vascular pathologies, respectively, having no statistical correlation between them (p > 0. 05). No arterial pathology was observed in any group. There was no correlation between the type of Peyronie's curvature and the penile doppler ultrasonographic findings in normopotent patients.Öğe Is the efficacy of in situ vaginal wall slings decreasing in the late follow-up?(Springer Nature B.V., 2008) Metin, Ahmet; Kayıgil, Önder; Ahmed, S. İftekhar; Atmaca, Ali FuatIntroduction The aim of this study was to assess the efficacy of in situ vaginal wall sling operations in the late follow-up period. Materials and methods In situ vaginal wall sling procedure was performed in 203 women with type II stress urinary incontinence between 1996 and 2003. Of these 203 patients, 105, 64 and 23 of them completed 3, 4 and 5 years follow-up evaluations, respectively, and were included in the study. Preoperative evaluations included physical examination, Bonney and Q-Tip tests, cystoscopic examination, and filing and voiding cystometry with pressure flow studies followed by abdominal leak point measurements. Results The cure, improvement and failure rates were found to be 80.9, 2.9 and 16.2% after 3 years follow-up, 65.7, 10.9 and 23.4% after 4 years follow-up and 60.8, 8.7 and 30.4% after 5 years follow-up. Temporary retention (21.6%), suture granuloma (2.9%) and pelvic pain (1.9%) were some of the complications we met following surgery. Conclusion We observed a yearly trend of decrease in efficacy.Öğe Obstructive urodynamic findings in idiopathic detrusor overactivity(Springer, 2007) Kayıgil, Önder; Metin, Ahmet; Atmaca, Ali FuatPurpose To investigate the obstructive findings urodynamically in idiopathic detrusor overactivity and compare them (maximum flow rate 'Q max' detrusor pressure at maximum flow 'PQ max') with control group. Materials and Methods Cystometric evaluation and pressure flow studies were performed in 25 women with symptoms of idiopathic detrusor overactivity and control group comprised 40 women with anatomic incontinence without cystocele. Patients with pelvic floor prolapse, motor urgency and poor compliance were excluded from the study. Q max less than 15 ml/s and PQ max more than 40 cm water were accepted as obstruction. Results After cystometric evaluation, obstruction was found in 36% of patients with idiopathic detrusor overactivity and 15% in control group. The range of maximum flow rate and PQ max values were 2-43.7 ml/s (mean 14.47 +/- 10.22) and 10-143 cm water (mean 58.97 +/- 35.13) in idiopathic urge syndrome group. These values were 6.6-51.8 ml/s (mean 23.24 +/- 12.43) and 9.7-61 cm water (mean 25.56 +/- 12.43) respectively in control group. Q max and PQ max parameters were compared statistically between the two groups. Idiopathic detrusor overactivity group had lower mean Q max and higher mean PQ max values than control group (P < 0.001) Table 1. Conclusion Obstruction percentage was found to be more in idiopathic detrusor overactivity group than the control group.Öğe Time-Dependent Changes in Biomechanical Properties of Four Different Synthetic Materials in a Rabbit Model and the Importance in Respect to Sling Surgery(Karger, 2008) Atmaca, Ali Fuat; Şerefoğlu, Ege Can; Eroğlu, Muzaffer; Gürdal, Mesut; Metin, Ahmet; Kayıgil, ÖnderAim: To examine the time-dependent biomechanical properties of four different implanted synthetic materials. Materials and Methods: 18 New Zealand rabbits were randomly categorized into three groups: group 1 to be evaluated at the 2nd week, group 2 at the 8th week, and group 3 at the 12th week. Before the implantation, baseline values were obtained. Each of the 2 x 5 cm sized materials of mersilene, prolene, ultrapro and vypro mesh were placed in the anterior abdominal fascia. The mesh materials were removed, tensile strength (N/mm(2)) and ultimate strain (%) were measured by tensinometry and surface area losses (cm(2)) were calculated. Results: Tensile strength values (mean +/- SD) were 9.2 +/- 1.5, 8.5 +/- 1.2 for mersilene, 25.2 +/- 7.3, 14.0 +/- 2.9 for prolene, 2.2 +/- 0.6, 12.5 +/- 1.4 for ultrapro and 8.1 +/- 1.6, 7.0 +/- 1.8 for vypro at baseline and the 12th week. Ultimate strain values (mean +/- SD) were 131.2 +/- 46.1, 110.4 +/- 98.6 for mersilene, 181.0 +/- 26.4, 78.5 +/- 14.4 for prolene, 91.5 +/- 8.2, 89.6 +/- 20.5 for ultrapro and 84.3 +/- 8.9, 55.0 +/- 13.2 for vypro at baseline and the 12th week. Surface areas (mean +/- SD) were 8.87 +/- 0.14, 9.38 +/- 0.17, 8.4 +/- 0.32 and 8.76 +/- 0.16 for mersilene, prolene, ultrapro and vypro at the 12th week respectively. Conclusions: Although prolene mesh demonstrated a decrease in its tensile strength it still remains the highest at the 12th week. Considering the significant time-dependent increase in its tensile strength, ultrapro mesh should be studied in humans. A final decision on the preference of ultrapro mesh in sling surgery could be reached after such studies. Copyright (C) 2008 S. Karger AG, Basel
