In flaccid bladder (also known as lower motor neuron or hypotonic bladder), the muscles of the bladder lose ability to contract normally. This can cause the inability to void urine even if the bladder is full and cause a large bladder capacity. The internal urinary sphincter can contract normally, however urinary incontinence is common.
The causes of pelvic floor dysfunction aren’t well understood. Experts know that weakened muscles and connective tissue in the pelvis can contribute to it, as can injuries to the pelvis.
Plasmolysis is the process in which cells lose water in a hypertonic solution. The reverse process, deplasmolysis or cytolysis, can occur if the cell is in a hypotonic solution resulting in a lower external osmotic pressure and a net flow of water into the cell.
In the longer term, obstruction of the urinary tract may cause: [citation needed] Bladder stones; Atrophy of the detrusor muscle (atonic bladder is an extreme form) Hydronephrosis (congestion of the kidneys) Hypertrophy of the detrusor muscle (the muscle that squeezes the bladder to empty it during urination)
One study showed that overactive bladder symptoms affect 27 percent of men over age 40 at least sometimes. If this description was of a 60-year-old woman, the leading diagnosis would be overactive ...
Without diagnostic evaluation, the cause of underactive bladder is unclear, as there are multiple possible causes. UAB symptoms can accurately reflect impaired bladder emptying due either to DU or obstruction (normal or large storage volumes, elevated post-void residual volume), or can result from a sense of incomplete emptying of a hypersensitive bladder (small storage volumes, normal or ...
Turgidity is the point at which the cell's membrane pushes against the cell wall, which is when turgor pressure is high. When the cell has low turgor pressure, it is flaccid. In plants, this is shown as wilted anatomical structures. This is more specifically known as plasmolysis. [7] A turgid and flaccid cell
Hard flaccid syndrome (HFS), also known as hard flaccid (HF), is a rare acquired dysautonomic condition characterized by a flaccid penis that remains in a firm, semi-rigid state in the absence of sexual arousal. Patients often describe their flaccid penis as firm to the touch, rubbery, shrunken, and retracted, frequently accompanied by pain ...
