It can be applied to meatal stenosis and strictures within approximately 1 cm from the meatus treatment 5th metacarpal fracture buy cheap meclizine 25mg, but works best for true meatal stenosis [29] treatment zenkers diverticulum cheap 25mg meclizine overnight delivery. To start medicinebg effective meclizine 25 mg, the extent of the stricture is identified to make certain that distal urethrectomy is appropriate. Sometimes, a small ventral urethrotomy is necessary to determine the proximal extent of the stricture. This is particularly useful as postoperative swelling can cause urinary retention. Distal Urethroplasty with Vaginal and Vestibular Inlay Flaps For distal strictures that have a proximal limit of up to 2 cm from the urethral meatus, a Blandy urethroplasty or proximally based vaginal pedicle inlay flap can be done. The procedure was originally described but never reported by Blandy, but was subsequently reported on by Schwender et al. This procedure recreates the ventral portion of the urethral meatus and replaces the distal ventral urethra with a flap of vaginal wall. As with any stricture, the first step is identifying the proximal extent of the stricture. Outcomes for Distal Urethral Reconstruction Early postoperative complications of distal urethral reconstruction are generally self-limiting and include bleeding, transient urinary retention secondary to swelling, and urinary tract infection. There is little in the literature regarding the outcomes for distal urethral reconstruction. Regarding distal urethrectomy and advancement meatoplasty, we would expect similar success rates. When this procedure occasionally fails, it is usually due to the reformation of scar tissue caused by inadequate resection at the initial procedure. The most critical components of both active and passive continence are located in this important segment of urethra. The Blandy proximally based vaginal flap urethroplasty (described earlier) can be used to treat some midurethral strictures, particularly those that are at the more distal portion of the midurethra. In cases of strictures that are isolated to the midurethra and do not include the distal urethra, one may also consider a free graft, such as buccal mucosa (see section "Onlay Urethroplasty Using a Free Graft" and Figure 111. Vaginal flap urethroplasty, popularized by Blaivas [33], can be utilized to recreate a functional urethra by way of local, healthy tissues. It can be used for strictures as well as ablation/erosion of the mid to distal urethra. This technique can also be applied in cases of a shortened urethra associated with vaginal voiding in order to improve urethral length. In cases of urethral stricture, a longitudinal incision is made in the anterior vaginal wall directly beneath the urethra. The urethra is exposed and a longitudinal incision is made in the ventral urethra exposing the entire segment of strictured or diseased urethra, until more proximal, viable tissue is identified. In cases of urethral ablation, the vaginal wall distal to the urethra meatus becomes the ventral plate of the urethra. There are two variations of the vaginal flap urethroplasty that we commonly employ. In the first, a flap of full thickness vaginal wall, including the epithelium, in a U configuration can be employed as a patch or ventral plate of neourethra (Figure 111. The second, for cases of urethral ablation, where there is compromised anterior vaginal wall tissue proximal to the urethra, medially based flaps can be created from the vaginal wall distal to urethra.

The ureter courses anterior to the psoas muscle then anterior to the iliac vessels medications ending in zole order 25 mg meclizine mastercard. The right ureter descends anteriorly over the duodenum and runs lateral to the inferior vena cava [10] medicine 319 pill order meclizine from india. The left ureter travels lateral to the aorta and runs close to the descending and sigmoid colon medicine go down discount generic meclizine uk. As the ureters approach the pelvis, they are crossed anteriorly by the ovarian vessels [10]. The right ureter enters the pelvis by crossing over the external iliac artery, while the left ureter crosses over 1753 the common iliac artery. In the middle of the pelvis, the ureter is crossed anteriorly by the uterine artery [13]. It is in this area that the ureters are mostly likely to be injured during hysterectomy. Histologically, the ureter is made of three layers that include an inner layer of transitional epithelium; a middle layer of longitudinal, circular, and smooth muscle; and an outer layer of adventitia [10]. The adventitial layer contains the blood and nerve supply as well as lymphatic drainage from the ureter [10]. The renal, ovarian, and common iliac arteries as well as the aorta all contribute to the blood supply of the ureter [12]. In the abdomen, the ureter derives its blood supply from all small arteries approaching it medially (from the aorta), where the pelvic ureter receives its blood supply from vessels approaching laterally (from the iliac arteries) [12]. The Bladder the bladder is positioned anterior to the vagina, cervix, and lower uterine segment. The vesicouterine fold/pouch is a reflection of the anterior peritoneum that lies between the dome of the bladder and the lower uterine segment. The bladder base is opposed to the cervix and vagina with the vesicocervical and vesicovaginal fascia. The bladder is typically described as consisting of the dome superior to the trigonal ridge and the base inferiorly [12]. The base contains the trigone, including the ureters, which enter posteriorly, and the urethra, which exits at the most inferior aspect of the bladder [12]. It can also be devascularized or denervated by sharp or blunt dissection, typically when the dissection is carried out (unintentionally) in a subadventitial plane. Thermal injury via electrocautery or other sources of energy such as a harmonic scalpel or laser can also compromise the ureteral vascular supply. As bladder or ureteral urinary leakage secondary to thermal injury typically occurs secondary to ureteral wall necrosis, the presentation is usually delayed until several days after surgery. On the other hand, direct injury to the bladder, on the other hand, usually occurs with either laceration to the bladder wall or accidental placement of a suture or staple [18,19]. Unrecognized placement of a permanent suture or metal staple into the bladder wall may initial be asymptomatic. Over time, however, exposure of the foreign body to urine typically leads to stone formation [20].

While these three products are no longer marketed by their respective companies in the United States medications zopiclone order 25mg meclizine otc, some trocar-based kits are still available in the United States and worldwide symptoms influenza purchase meclizine american express. First medications narcolepsy cheap meclizine 25 mg otc, a weighted speculum, self-retaining retractor, or Deaver retractors are placed in the vagina. Allis clamps are positioned at the urethrovesical junction for traction and 1 cm distal to the vaginal apex. As opposed to an anterior colporrhaphy in which the vaginal epithelium and muscularis are split for plication, the mesh is placed underneath the muscularis to maintain a thickened vascularized epithelium in order to minimize mesh exposure or erosion. To enter this potential space, the surgeon injects a dilute vasopressin solution or 0. Irrigation may help during the dissection, as the defect is a glistening white line. A sagittal colpotomy incision is made between the Allis clamps long enough to admit two fingers comfortably. Next, countertraction along the entire incision line is achieved with either the serial Allis clamps or a self-retaining retractor. The vaginal epithelium and full-thickness muscularis are dissected away from the bladder defect. Sharp and blunt dissection of the bladder is then performed while keeping the muscularis and epithelium on the vaginal flaps. A number of different trocar types are available including helical-shaped trocars similar to those for transobturator slings and flexible straight trocars. When placing multiple mesh arms through the transobturator space, the superior and inferior puncture sites should be at least 3 cm apart so the mesh can lay flat. Two fingers placed into the vagina can retract the colon, elevate the bladder, and minimize deviation of the trocar tip with direct palpation. If the surgeon conserves the uterus, then permanent sutures can be placed into the cervical stroma to stabilize the mesh. Cystoscopic and rectal examinations before, during, and after each portion of the surgery can be helpful. Once adequate hemostasis is obtained, the vaginal epithelium is closed with a continuous nonlocking stitch of delayed absorbable suture. Placing a lubricated vaginal pack may minimize bleeding and keep the mesh flat during healing. After desired tensioning, all ends of the mesh arms should be trimmed below the surface of the skin and the incisions closed. Concurrent procedures, such as a midurethral sling, should be done through a separate vaginal incision at this time. Nontrocar Mesh Kits the nontrocar or "single-incision" mesh kits have become increasingly popular and largely replaced trocar-based kits. The products avoid the potential complications associated with blind trocar passage through the transobturator space and ischiorectal fossa and allow mesh fixation via direct visualization. Additionally, most currently available nontrocar kits provide apical fixation to the sacrospinous ligaments bilaterally as well as anterior vaginal support. The technique for the nontrocar kits begins similarly to the technique for trocar-guided kit placement. For apical fixation, the surgeon palpates the location of interest then identifies the sacrospinous ligament at least 2 cm medial to the ischial spine.

The approach chosen depends on several factors that include patient presentation treatment of strep throat buy discount meclizine 25mg online, type of initial anti-incontinence surgery medications information generic meclizine 25 mg with amex, history of prior urethrolysis symptoms you need glasses buy 25mg meclizine visa, and surgeon and patient preference. In general, proceeding from the less morbid transvaginal approach and reserving the retropubic approach for failures is prudent. However, exceptions exist that would favor a retropubic approach as the primary initial procedure such as inadequate vaginal access precluding a transvaginal approach, in cases where the original anti-incontinence surgery was performed transabdominally or associated with bladder perforation, fistula, or other operative complication, after a Burch resuspension, or associated with intravesical mesh exposure, which must be removed. This was felt secondary to the inability to reach proximal most sutures transvaginally. Transvaginal Urethrolysis In 1984, Leach and Raz described the transvaginal technique of urethrolysis, and though variations have been published since, it is still the most commonly used today [63]. Dissection proceeds laterally along the glistening surface of the periurethral fascia to the pubic bone. The retropubic space is entered sharply by perforating the attachment of the endopelvic fascia to the obturator fascia (Figure 79. The urethra is dissected bluntly and sharply off the undersurface of the pubic bone and completely freed proximally to the bladder neck. Some separation of the urethra from the pubis is done blindly with the Metzenbaum scissors (Figure 79. Care should be taken to stay as close to the underside of the pubis as possible, and manual palpation of this plane along with an awareness of the location of the urethral catheter provides a proprioceptive map in this hard-to-visualize space. If an inadvertent injury to the urethra or anterior bladder wall near the bladder neck is caused, primary repair should be attempted and completion of the procedure should be entertained as further bladder or urethral wall damage can occur. Fistula formation is minor as the area of perforation is well away from the vaginal incision. Once sufficient space is developed in this plane, the remaining adhesions and scar can be swept down bluntly with an index finger. If suspension sutures are felt, a clamp can be used to bring it into view so it can be cut safely. After this initial mobilization, a right-angle clamp can be placed between the pubic bone and the urethra, and a Penrose drain is placed around the urethra. Downward traction is applied on the Penrose drain to aid visualization and all remaining retropubic attachments are dissected free (Figure 79. At this point, the urethra should be freely mobile in all planes, and this can be tested with movement of an intraurethral sound or cystoscope. Cystoscopy should be performed to rule out urethral and/or bladder injury prior to vaginal closure. It is also good practice to assess ureteral integrity by giving intravenous indigo carmine or methylene blue to assure efflux. The endopelvic fascia, periurethral fascia, and vaginal wall are retracted medially to expose the urethra in the retropubic space. With tension on the upper edge, the perineal membrane is perforated and all attachments, scar, and sutures between the pubic bone and urethra are incised sharply with scissors. An index finger can be followed along the underside of the pubis into the retropubic space. With a sweeping motion directed laterally and posteriorly, obstructing bands can be identified and either bluntly or sharply freed.
