BACKGROUND: Catheter-related bladder discomfort (CRBD) to an indwelling urinary catheter is defined as a painful urethral discomfort, resistant to conventional opioid therapy, decreasing the quality of postoperative recovery. According to anatomy, the branches of sacral somatic nerves form the afferent nerves of the urethra and bladder triangle, which deriving from the ventral rami of the second to fourth sacral spinal nerves, innervating the urethral muscles and sphincter of the perineum and pelvic floor; as well as providing sensation to the penis and clitoris in males and females, which including the urethra and bladder triangle...

Sarcopenia and cachexia present characteristic features of a decrease in skeletal muscle mass and strength, anorexia, and lack of motivation. Treatments for these diseases have not yet been established, although selective androgen receptor modulators (SARMs) are considered as therapeutic targets. We previously reported that a novel SARM compound, SARM-2f, exhibits anabolic effect on muscles, with less stimulatory effect on prostate weight compared with testosterone, in rat Hershberger assays and cancer cachexia models...

INTRODUCTION AND HYPOTHESIS: We studied the geometry of and changes in structures that play an important role in stabilizing the pelvic system during pregnancy using a numerical system at different gestational ages and postpartum. METHODS: We developed a parturient numerical model to assess pelvic structures at different gestational stages (16, 32, and 38 weeks) and postpartum (2 months and 1 year) using magnetic resonance imaging (MRI). Organs, muscles, and ligaments were segmented to generate a 3D model of the pelvis...

We report a case of 62-year old women with skin infiltration in the perineal area after anterior rectal resection due to upper rectal cancer. Computed Tomography (CT) shows an intense infiltrative aspect of the lesion. The patient had a diffuse perineal infiltration predominantly at Levator Ani muscles and adhesions to the posterior parts of urinary bladder, uterus, vagina and perineal skin. The patient underwent surgery with colostomy to relieve the colonic tract due to obstruction and later was treated with chemo-radiation...

BACKGROUND: Parity is the greatest risk factor for the development of pelvic organ prolapse. The normally supported vagina is pulled up and back over the levator ani. Loss of vaginal angulation has been associated with prolapse and may represent injury to the vaginal supportive tissues. OBJECTIVE: We proposed and examined the following hypotheses: (1) pregnancy and delivery impact vaginal support, leading to loss of vaginal angle; (2) vaginal angulation is restored postpartum; and (3) uncomplicated vaginal delivery (VD) is associated with accelerated remodeling of the vaginal fibrillar matrix...

Purpose: Tumors at the level of the anorectal junction had required total levator-ani muscle excision to achieve an adequate resection margin. However, in the cases of tumor invading ipsilateral levator-ani muscle and intact external sphincter, en bloc resection of rectum with levator-ani muscle including tumor would be possible. This hemilevator excision (HLE) technique enables preserving the anal sphincter function while obtaining oncologic clearance and avoiding permanent colostomy in those patients...

BACKGROUND: The internal anal sphincter (IAS) contributes substantially to anorectal functions. While its autonomic nerve supply has been studied at the microscopic level, little information is available concerning the macroscopic topography of extrinsic nerve fibres. This study was designed to identify neural connections between the pelvic plexus and the IAS, provide a detailed topographical description, and give histological proof of autonomic nerve tissue. METHODS: Macroscopic dissection of pelvic autonomic nerves was performed under magnification in seven (5 males, 2 females) hemipelvises obtained from body donors (67-92 years)...

Coccygodynia is a problem with a small percentage (1%) of the population suffering from musculoskeletal disorders. This pain is often associated with trauma, falling on the tailbone, long cycling, or by women after childbirth. The reason for the described problem can be the actual morphological changes. Idiopathic coccygodynia causes therapeutic difficulties to specialists of many fields. Unsatisfactory treatment, including coccygectomy tends to seek new solutions. They belong to them techniques exploited in the manual therapy which in their spectrum hold: direct techniques - per rectum as well as indirect techniques taking into account distant structures of the motor organ, remaining in dense interactions with the coccygeal part...
