Cecal perforation complicating placement of a transvaginal tension-free vaginal tape.

The tension-free vaginal tape has been increasingly used to treat stress urinary incontinence. This procedure has a high success rate and unique surgical complications. The patient is a 39-year-old with genuine stress urinary incontinence and underwent placement of tension-free vaginal tape for treatment. Twelve hours after the procedure, the patient had increasing abdominal pain, and an acute abdominal series showed free intraperitoneal air. Exploratory laparotomy revealed stool in the peritoneal cavity, with the vaginal tape placed through the cecum. Bowel complications are rare; however, they may occur and should be suspected in a patient with an acute abdomen and free air.

Urogynecology practice patterns among Air Force obstetricians and gynecologists: survey results.

The objective of this study was to describe the practice patterns of physicians in the United States Air Force regarding the evaluation and treatment of female pelvic floor disorders including urinary incontinence and pelvic organ prolapse. A self-administered survey of 22 questions was electronically mailed to all active duty Air Force obstetricians & gynecologists. Fifty-one surveys were returned for a 51% response rate. Eighty-four percent of physicians treat urinary incontinence. A smaller percentage perform advanced reconstructive techniques, using biomaterials (35%), colpocleisis (39%), overlapping sphincter repairs (45%), and abdominal sacrocolpopexy (27%). When questioned about urogynecology training during residency, most respondents report inadequate training in advanced pelvic surgery techniques. In conclusion, the majority of Air Force obstetricians and gynecologists feel comfortable treating uncomplicated urinary incontinence but do not routinely perform advanced urogynecology surgeries. There is a continued need to train physicians in female pelvic medicine to treat a unique patient population.

A comparison of anticipatory and postprocedure pain perception in patients who undergo urodynamic procedures.

OBJECTIVE: The purpose of this study was to compare anticipatory and postprocedure pain perception in female patients who undergo multichannel urodynamic evaluation in an office setting. STUDY DESIGN: One hundred consecutive patients completed a visual analogue pain scale before and after urodynamic testing. RESULTS: The mean postprocedure pain score of 2.32 cm was significantly lower than the anticipatory pain rating of 4.35 cm (P<.05). The lower postprocedure pain score was not influenced by previous hysterectomy, body mass index, menopausal status, estrogen replacement therapy, or analgesic or psychiatric medication usage. Patients who had undergone previous anti-incontinence surgery reported significantly higher levels of pain during the procedure (mean visual analogue pain scale score, 3.10 cm vs 2.06 cm; P=.027). CONCLUSION: Patients who undergo urodynamic testing anticipate higher degrees of discomfort than they perceive during the procedure. Previous anti-incontinence surgery appears to lower the pain threshold.

Voiding dysfunction after surgery for stress incontinence: literature review and survey results.

Postoperative voiding dysfunction is a potential complication of anti-incontinence procedures. Reported rates of urethral obstruction range from 5% to 20%. There is a lack of consensus in the literature regarding the appropriate evaluation and management of this distressing problem. A literature search was carried out using Medline (1966-2001) for postoperative voiding dysfunction. The key word urethrolysis was cross-referenced with surgical complications and stress urinary incontinence to identify all published English-language articles. The bibliographies of reviewed articles were searched manually. We also mailed a survey to the members of American Urogynecologic Society (AUGS) regarding their management of this problem. Overall, 262 members (31.4%) responded to the survey. Success rates reported in the literature between retropubic and vaginal techniques of urethrolysis are comparable, but morbidity is lower with the vaginal approach. The success rates are equivalent with (68%) or without (74%) resuspension following transvaginal urethrolysis. The incidence of postoperative SUI is acceptably low even without resuspension of the urethra (6% for both). Results of the AUGS survey reveal that most providers favor a transvaginal approach (74%) when performing urethrolysis, and they do not routinely resupport the bladder neck (82%).

Acute renal failure caused by complete bladder eversion through a vesicovaginal fistula.

We report a rare case of bladder eversion through a vesicovaginal fistula. The bladder prolapse was almost complete, resulting in ureteral kinking, bilateral hydronephrosis and acute renal failure. After reduction of the bladder eversion, bilateral ureteral stent placement, fistula repair using the Latzko technique and colpocleisis, the patient had rapid resolution of her renal compromise.

A comparison of anticipated pain before and pain rating after the procedure in patients who undergo cystourethroscopy.

OBJECTIVE: The purpose of this study was to compare anticipated pain before the procedure and actual pain rating after the procedure in female patients who undergo cystourethroscopy. STUDY DESIGN: Eighty-seven consecutive female patients completed a 10-cm visual analog pain scale before and after cystourethroscopy. A 24F urethroscope was used initially to inspect the urethra and was followed by a systematic survey of the bladder with a 17F cystoscope that was lubricated with 2% lidocaine gel. The visual analog pain scale scores were evaluated for significance with the use of the Student t test and the Pearson correlation coefficient. RESULTS: Visual analog pain scale analysis demonstrated a mean anticipated pain score of 3.75 cm before the procedure versus a mean pain rating score of 2.83 cm after the procedure (P <.05). Neither a history of previous cystoscopy (visual analog pain scale score, 3.03 vs 2.30 cm; P =.18) nor talking with someone about the procedure beforehand (visual analog pain scale score, 2.74 vs 2.89 cm; P =.76) influenced the lower pain rating after the procedure. There was no significant correlation between age, parity, body mass index, or presence of pelvic organ prolapse and anticipated or realized pain perception. CONCLUSION: Patients who undergo cystourethroscopy consistently anticipate higher degrees of discomfort than they actually perceive during the procedure.

Ectopic IUD complicating pregnancy. A case report.

BACKGROUND: For the most part, intrauterine devices (IUDs) have a low complication rate and minimal side effects. However, one of the most common reasons for contraceptive failure while using an IUD is its translocation or extrauterine migration. Pregnancy complicated by translocation or an ectopic IUD can present a formidable clinical challenge. CASE: A 23-year-old woman, gravida 3, para 2, using a copper-7 IUD for contraception, presented at 7 weeks' gestation. Transvaginal sonogram confirmed the presence of a fetal pole with cardiac activity; however, the IUD was not detectable. An anteroposterior roentgenogram showed 90 degrees counterclockwise rotation of the IUD relative to the normal position. Laparoscopy was performed at 14 weeks. The IUD was extrauterine, buried in omental adhesions attached to the anterior abdominal wall. The IUD was dissected free and removed without difficulty. The remainder of the pregnancy was uncomplicated. CONCLUSION: Uterine perforation is a recognized and potentially hazardous complication of IUD use. Localization of a lost IUD should follow an organized and systematic approach utilizing an assortment of radiologic and operative techniques. We report the third known case utilizing laparoscopy to remove an ectopic IUD complicating early pregnancy. Laparoscopy, even during pregnancy, has proven to be a safe and simple tool for managing a variety of surgical conditions.
