Histopathological and Mechanical Properties of Different Meshes in a Rat Model of Pelvic Prolapse Surgery
(Yuzuncu Yil Universitesi Tip Fakultesi, 2017) Elçi, G.G.; Elçi, E.; Kaya, C.; Çim, N.; Kolusarı, A.; Erten, R.; Bulut, G.
Different types of mesh materials are used to support pelvic structures in urogynecologic procedures. Our aim was to compare histopathological and mechanical effects of Prolene®, UltraPro®, Vypro II®, and Permacol® meshes used in pelvic organ prolapse. Thirty Sprague-Dawley rats were randomized into five groups. Group 1 served as a sham-operated control (n=6); Prolene® was used in group 2 (n=6), UltraPro® in group 3 (n=6), Vypro II® in group 4 (n=6), and Permacol® in group 5 (n=6). A 0.5 × 1 cm mesh was placed between the paravaginal tissue and bladder. After 12 weeks, the rats were reoperated and meshes were excised. Histopathological tissue reactions were compared. The muscle penetration rate was 67% in the Prolene® group, which was significantly higher than that in the other groups (p=0.026). Minimum preserved postoperative surface area was seen with Prolene® at 0.31 cm2 and maximum with UltraPro® at 0.45 cm2, which was statistically significant. UltraPro® had the most preserved postoperative surface area and less shrinkage than the other meshes. The mesh materials cause an inflammatory reaction in surrounding tissue. Prolene® mesh had superior muscle penetration and tensile strength compared to the other materials. © 2017, Yuzuncu Yil Universitesi Tip Fakultesi. All rights reserved.
Modified Raz Operation Backed With Periurethral Roll Mesh in Female Stress Urinary Incontinence
(verduci Publisher, 2012) Pirincci, N.; Kamberoglu, H.; Kaya, C.; Kaba, M.; Gecit, I.; Gunes, M.; Karaman, M. I.
OBJECTIVES: With the modifications that we made, the aim is to increase the effectiveness and the success rate of the Raz operation in the treatment of stress urinary incontinence (SUI) and to present a new approach in the treatment by reducing the complication rates. PATIENTS AND METHODS: Between November 2002 and December 2010, the Raz operation that we modified with the changes such as the placement of cystostomy catheter with the Lowsley clamp, vaginal incision of the bilateral oblique, the placement of periurethral roll mesh, the use of a single 0-degree stamey needle instead of a double needle applicator, binding the sutures mutually and on the support of the polypropylene mesh in suprapubic region was performed to 81 female patients with SUI in lithotomy position under the regional anesthesia. RESULTS: We performed the modified Raz operation to 81 female patients with SUI, who had the complaint of urinary incontinence with the effort lasting for about 4.5 years (between 1-16 years) and whose ages were 28-83 years (mean 55.2 years), childbirth numbers were 0-11 (mean 4.8), weights were 60-85 kg (mean 69.3 kg), and 32 of whom (39.5%) were of grade 1, 49 of whom (60.5%) were of grade 2 with the anamnesia of SUI, and whose stres test was (+) in the physical examination. While the duration of the operation was 39.8 minutes (20-85 minutes) and the duration of the hospitalization was 2.9 days (2-4 days), the duration of the stay of the patients with the cystostomy catheter was determined to be 4.8 days (3-11 days). We found the rate of our success as 93.8% according to the objective criteria. CONCLUSIONS: With the modifications that we made, we increased the success rate of the Raz operation and reduced the rates of the complication. We believe that the place of our modification method in incontinence surgery becomes more clearly with the comparison of the other anti-incontinence surgery techniques in patient groups with the same characteristics.
