Sling surgery has supplanted other anti-incontinence procedures as the treatment of choice for stress urinary incontinence. Iatrogenic obstruction after sling surgery is increasingly reported as the procedure becomes more and more popular. The rate of retention (defined as catheter-dependency for at least 28 days) has been estimated at 1-10%. Iatrogenic obstruction after sling surgery has a variable presentation and can include urinary urgency, urgency incontinence, hesitancy, straining to void, weak urinary stream, nocturia, incomplete emptying, frequency, dysuria or urinary tract infections. The evaluation and diagnosis rely upon a thorough patient history, physical examination, a urine flow test and postvoid residual volume. Cystoscopy and pressure-flow studies can also be considered. The single most important factor in the diagnosis of sling-related obstruction or voiding dysfunction is the temporal relationship between the sling procedure and onset of symptoms. Transient urinary retention can be managed with indwelling or intermittent catheter drainage. For those patients with moderate or symptomatic retention, surgical options for treatment include sling loosening, sling incision, sling excision, and urethrolysis.

The primary objectives were to describe the rate of repeat surgery for stress urinary incontinence (SUI) after release of an obstructing synthetic mid-urethral sling (MUS) and to evaluate the effect o...
A sling at time of sacral colpopexy (SCP) for apical pelvic organ prolapse (POP) is valuable in the treatment of overt, urodynamic, and occult stress urinary incontinence (SUI). As there is no current...
Secondary nasal obstruction occurs when surgery fails to improve a patient's nasal obstruction symptoms. This may occur from failure to recognize a problem preoperatively or failure to address mucocut...
To determine the significance of bladder trabeculations seen on preoperative cystoscopy prior to midurethral sling surgery with respect to lower urinary tract symptoms and sling outcomes.
This double-blind randomized controlled trial seeks to find a better treatment for women with mixed urinary incontinence (both stress and urgency incontinence). The primary aim is to deter...

Functional obstruction of the COLON leading to MEGACOLON in the absence of obvious COLONIC DISEASES or mechanical obstruction. When this condition is acquired, acute, and coexisting with another medical condition (trauma, surgery, serious injuries or illness, or medication), it is called Ogilvie's syndrome.
Blockage in any part of the URETER causing obstruction of urine flow from the kidney to the URINARY BLADDER. The obstruction may be congenital, acquired, unilateral, bilateral, complete, partial, acute, or chronic. Depending on the degree and duration of the obstruction, clinical features vary greatly such as HYDRONEPHROSIS and obstructive nephropathy.
Absence of urine formation. It is usually associated with complete bilateral ureteral (URETER) obstruction, complete lower urinary tract obstruction, or unilateral ureteral obstruction when a solitary kidney is present.
Hindrance of the passage of luminal contents in the DUODENUM. Duodenal obstruction can be partial or complete, and caused by intrinsic or extrinsic factors. Simple obstruction is associated with diminished or stopped flow of luminal contents. Strangulating obstruction is associated with impaired blood flow to the duodenum in addition to obstructed flow of luminal contents.
A slowly hydrolyzed muscarinic agonist with no nicotinic effects. Bethanechol is generally used to increase smooth muscle tone, as in the GI tract following abdominal surgery or in urinary retention in the absence of obstruction. It may cause hypotension, cardiac rate changes, and bronchial spasms.
Stress is caused by your perception of situations around you and then the reaction of your body to them. The automatic stress response to unexpected events is known as 'fight or flight'. Discovered by Walter Cannon in 1932, it is the release of h...
