Needle bladder neck suspension, also known as needle suspension, or paravaginal surgery, is performed to support the hypermobile, or moveable urethra using sutures to attach it to tissues covering the pelvic floor. Of the three popular surgical procedures for urethral instability and its results in urinary stress incontinence, needle bladder neck suspension is the quickest and easiest to perform. It has many variants, such as the Raz, Stamey, modified Pereyra, or Gattes procedures, but its long-term results are less impressive than other, more extensive, anti-incontinent surgeries.
Fifty years of surgical attempts to treat incontinence, especially in women, has resulted in three types of surgery tied to essentially three causes of a particular type of incontinence related to muscle weakening of the urethra and the "gate-keeping" sphincter muscles. Stress urinary incontinence, the uncontrollable leakage of urine when pressure is put on the bladder during sneezing, coughing, laughing, or exercising, is very common in women, and is estimated to affect 50% of elderly women in long-term care facilities. The inability to hold urine has two causes. One has to do with support for the urethra and bladder, known as genuine stress incontinence (GSI), and the other is related to the inability of sphincter muscles, or intrinsic sphincter deficiency (ISD), to keep the opening of the bladder closed.
In GSI, weak muscles supporting the urethra allow it to be displaced and/or descend into the pelvic-floor fascia (connective tissues) and create cystoceles, or pockets. The goal of surgery for GSI is to stabilize the suburethral fascia to prevent the urethra from being overly mobile during increased abdominal pressure.
The other major source of stress incontinence is due to weakening of the internal muscles of the sphincter, as they affect closure of the bladder. These muscles, called the intrinsic sphincter muscles, regulate the opening and closing of the bladder when a decision is made to urinate. Deficiency of the intrinsic sphincter muscles causes the opening to remain open and thus leads to chronic incontinence. ISD is a source of severe stress incontinence and may be combined with urethral hypermobility.
The challenge of surgery for stress incontinence is to adequately evaluate the actual source of incontinence, whether GSI or ISD, and also to determine the likelihood of cystoceles that may need repair. Under good diagnostic conditions, surgery for stress incontinence will utilize a suprapubic (above the pubic area) procedure, or Burch procedure, to secure the hypermobile urethra and stabilize it in a neutral position. Surgery for ISD uses what is known as a sling procedure , or "hammock" effect, that uses auxiliary tissue to undergird the urethra and provide contractive pressure to the sphincter. Most stress incontinence surgeries fall into one of these two procedures and their variants.
Needle neck bladder suspension, the third most utilized procedure for stress incontinence, simply attempts to attach the urethra neck to the posterior pelvic wall through the vagina or abdomen in order to stabilize the urethra. It is, however, considered a poor choice in comparison to the other two procedures because of its lack of long-term efficacy and its high incidence of urinary retention as an operative complication.
More than 13 million people in the United States, both males and females, have urinary incontinence. Women experience it twice as often as men due to pregnancy, childbirth, menopause, and the structure of the female urinary and gynecological systems. Anyone can become incontinent due to neurological injury, birth defects, cardiac conditions, multiple sclerosis, and chronic conditions in later life. Incontinence does not naturally accompany old age but is associated with many chronic conditions that occur as age increases. Incontinence is highly associated with obesity and lack of exercise . As many as 15–30% of adults over 60 have some form of urinary incontinence. Stress incontinence is, by far, the most frequent form of incontinence and is the most common type of bladder control problem in younger and middle-age women.
Needle bladder neck suspension surgery can be performed as open abdominal or vaginal surgery, or laproscopically, which allows for small incisions, video magnification of the operative field, and precise placement of sutures. Under a general anesthetic, the patient is placed in a position on her back with legs in stirrups allowing access to the suprapubic area. A Foley catheter is inserted into the bladder. The open procedure involves the passage of a needle from the suprapubic area to the vagina with multiple sutures through looping. Cytoscopic monitoring (using an endoscope passed into the urethra) prevents passage of the needle through the bladder or the urethra. The laproscopic method allows visualization of the needle pass made from the suprapubic area to the vagina and the looping technique. The vagina and the surrounding areas are thoroughly irrigated with an antibiotic solution throughout the procedure. The patient is discharged the same evening or the next morning with the catheter in place. She is kept on antibiotics and examined on the fourth day after surgery with the removal of the catheter. The follow-up examination includes wound inspection and a evaluation of residual urine. A pelvic examination is performed to check for bleeding or injury.
Stress urinary incontinence can have a number of causes. It is important that patients confer with their physicians to rule out medication-related, psychological, and/or behavioral sources of incontinence as well as physical and neurological causes. This involves complete medical history, as well as medication, clinical, neurological, and radiographic evaluations. Once these are completed, urodynamic tests that evaluate the urethra, bladder, flow, urine retention, and leakage, are performed and allow the physician to determine the primary source of the stress incontinence. Patients who are obese and/or engage in high-impact exercise are not good candidates for this surgery. Patients with ISD may not be cured with this procedure, since it is primarily intended to treat the hypermobile urethra.
Urologic surgery has inherent morbidity and mortality risks related primarily to general surgery , with lung conditions, blood clots, infections, and cardiac events occurring in a small percentage of surgeries, independent of the type of procedure. In addition, the American Urological Association (AUA) has concluded that needle suspension surgery has a number of complications related directly to suturing in the suprapulic area. These complications include:
These operative complications, coupled with the procedure's high rate (10%) of reported pain after surgery, and its relatively high rate (5%) of urinary retention lasting longer than four weeks, have resulted in needle neck suspension having a limited role in the management of stress urinary incontinence.
Despite modifications in the needle suspension procedure, the long-term outcome of the procedure does not indicate its lasting efficacy. According to a recent report by the AUA, a study of the effects of needle suspension found only a 67% cure, or "dry rate," after 48 months, with delayed failures of sutures in a very high percentage (33-80%) of cases.

Surgery is performed by a urological surgeon who has a medical degree with advanced training in urology and in surgery. Surgery is performed in a general hospital.
injury to my bladder , it turns out the needle used was defective and broke and therefore major
surgery was performed to retrieve the needle , a C-Section cut was made , as it turns out
when the needle broke it punctured my bladder , the Doctor a (Gyn) not a urologist told me immediately upon awakening from the surgery. I read some complications that occur with this type
surgery and I have alot of the same symptoms. But most importantly I do not feel then or even now that the surgery was effective. Now I am left with alot of questions , beginning with the Doctor , The Doctor was a GYN. not a Urologist , the manufacture of the needle used in my surgery
obviously it was defective. Do I have to worry or should this be further investigated , as far as if the same mesh was used , Im not quite sure , but then again I wouldn't be at all surprised.
