Introduction And Hypothesis:
To elevate and suspend the apical end of the vagina, the uterosacral ligaments (USL) were replaced by polyvinylidene fluoride (PVDF) structures. These PVDF structures were placed in the peritoneal folds of the USL at the pelvic wall to mimic the lateral and backward tension and to avoid rectal obstruction. A special tunneling device was used, which allowed the semi-circular placement of the structure without destroying the peritoneum.
Methods:
A 59-year-old woman with mixed urinary incontinence and apical prolapse (pelvic organ prolapse quantification system, POP-Q, stage 2) of the uterus underwent laparoscopic bilateral USL replacement. USLs were replaced by PVDF structures by performing the cervicosacropexy (CESA) technique using a semi-circular tunneling device.
Results:
Apical support was restored (POP-Q stage 0), and the patient was continent thereafter. The tunneling device was pulled through the peritoneal folds of the USLs toward the cervix. The new USL structures were brought to their physiological position. The new technique did not lead to any complications and did not cause any side effects during 1-year follow-up.
Conclusions:
Restoration of apical prolapse and urinary continence was achieved by bilateral USL replacement using a semi-circular tunneling device that was inserted through the lateral abdominal trocar incision.

Introduction to Functional Groups
Functional groups are group of atoms with specific chemical properties that occur within organic molecules and sometimes denoted as “R”. Functional groups are found along the carbon backbone of macromolecules can form chains or rings of carbon atoms. Functional groups can “functionalize” a compound by enabling it to adopt different physical and chemical properties.
Types of common functional groups

Introduction to the Cytoskeleton
The cytoskeleton is a network of protein filaments present within the cell, having three distinct filaments ̶ microfilaments, microtubules, and intermediate filaments. Each has characteristic features that distinguish them, including the dynamics of their assembly and disassembly, mechanical properties, polarity, and the type of molecular motors associated with them. Earlier, they were thought to be present only in eukaryotic cells; however, their...
Introduction to Urinary System
The kidneys are bean-shaped organs located in the retroperitoneal space, on either side of the vertebral column, between the T12 and L3 vertebrae. They are partially protected by the rib cage and surrounded by perirenal fat, which provides cushioning. They are responsible for urine formation and play critical roles in regulating blood pressure, electrolyte levels, and hormone production. The ureters...
