Comparison of laparoscopic and abdominal sacrocolpopexy for the treatment of vaginal vault prolapse.

BACKGROUND AND PURPOSE: Laparoscopic sacrocolpopexy (LSCP) offers a minimally invasive treatment for vaginal vault prolapse. We describe the surgical technique and offer insight into the learning curve. In addition, we performed a case series review comparing the laparoscopic procedure with its open surgical counterpart with respect to various demographic and perioperative parameters. PATIENTS AND METHODS: The Institutional Review Board-approved continence database at our institution was queried to identify all patients undergoing sacrocolpopexy between August 1999 and October 2004. The LSCP was performed in 25 patients, and open abdominal sacrocolpopexy (ASCP) was performed in 22 patients. Data were analyzed using Student's t-test and the Fisher exact test. RESULTS: No significant difference was observed in the demographic characteristics of the patients undergoing the two approaches. The mean estimated blood loss (P = 0.0002) and mean length of hospitalization (P < 0.0001) were significantly less for LSCP, whereas the operative time was significantly longer (219.9 minutes v 185.2 minutes; P = 0.045). The success rate for LSCP at 5.9 months was 100%; the ASCP success rate at 11.0 months was 95%. CONCLUSIONS: Laparoscopic sacrocolpopexy led to shorter hospitalization, better hemostasis, and less pain than the open procedure. Early follow-up suggests that LSCP is as effective as ASCP for the treatment of vaginal vault prolapse.

Hair as nidus for ureteral calculus formation: case report.

A 52-year-old man with a significant history of nephrolithiasis was found to have a calcium oxalate dihydrate ureteral calculus that apparently formed on a hair. This nidus may have been introduced during previous instrumentation, perhaps on the tip of the ureteroscope, laser fiber, or even during the placement of a ureteral stent.

Time management in the operating room: an analysis of the dedicated minimally invasive surgery suite.

BACKGROUND: Dedicated minimally invasive surgery suites are available that contain specialized equipment to facilitate endoscopic surgery. Laparoscopy performed in a general operating room is hampered by the multitude of additional equipment that must be transported into the room. The objective of this study was to compare the preparation times between procedures performed in traditional operating rooms versus dedicated minimally invasive surgery suites to see whether operating room efficiency is improved in the specialized room. METHODS: The records of 50 patients who underwent laparoscopic procedures between September 2000 and April 2002 were retrospectively reviewed. Twenty-three patients underwent surgery in a general operating room and 18 patients in an minimally invasive surgery suite. Nine patients were excluded because of cystoscopic procedures undergone prior to laparoscopy. Various time points were recorded from which various time intervals were derived, such as preanesthesia time, anesthesia induction time, and total preparation time. A 2-tailed, unpaired Student t test was used for statistical analysis. RESULTS: The mean preanesthesia time was significantly faster in the minimally invasive surgery suite (12.2 minutes) compared with that in the traditional operating room (17.8 minutes) (P=0.013). Mean anesthesia induction time in the minimally invasive surgery suite (47.5 minutes) was similar to time in the traditional operating room (45.7 minutes) (P=0.734). The average total preparation time for the minimally invasive surgery suite (59.6 minutes) was not significantly faster than that in the general operating room (63.5 minutes) (P=0.481). CONCLUSION: The amount of time that elapses between the patient entering the room and anesthesia induction is statically shorter in a dedicated minimally invasive surgery suite. Laparoscopic surgery is performed more efficiently in a dedicated minimally invasive surgery suite versus a traditional operating room.

Suitability of different sling materials for the treatment of female stress urinary incontinence.

Stress urinary incontinence (SUI) is defined as leakage of urine with a sudden increase in intra-abdominal pressure, such as that seen with laughing, lifting, or changing position, without a concomitant rise in detrusor (bladder-generated) pressure. The proposed mechanism of SUI is that an increase in intra-abdominal pressure resulting from various activities causes the bladder pressure to rise above the urethral pressure. The pubovaginal sling remains the standard treatment for female SUI in the US. The market has been flooded with innumerable sling materials. This review discusses the currently available sling materials, surgical approaches, and clinical outcomes data. Long-term data on efficacy is lacking, but early results with new materials and delivery techniques indicate that excellent cure rates with minimal morbidity and high patient satisfaction may be achievable.

Initial experience with rectocele repair using nonfrozen cadaveric fascia lata interposition.

OBJECTIVES: To describe a rectocele repair reinforced with solvent-dehydrated, gamma-irradiated, human fascia lata and report our early results with a technique we are confident will have a greater, more durable success rate, with a lower incidence of dyspareunia, than the classic repair. METHODS: A total of 73 patients, aged 31 to 86 years, with symptomatic (stool trapping and/or vaginal/perineal splinting or postural modifications to facilitate stool evacuation) rectoceles underwent a site-specific repair reinforced with cadaveric fascia. Perioperative questionnaires, retrospective chart review, and telephone interview by a blinded third-party reviewer and physical examination was conducted. Issues thought to be relevant to the rectocele repair were assessed. RESULTS: Of the 73 patients, 62 responded to the postoperative questionnaire and 50 underwent physical examination. The mean follow-up was 13.7 months (range 6 to 23). Of the 62 patients, 52 (93.6%) denied postoperative stool trapping requiring vaginal/perineal splinting. Of the 39 sexually active patients, 4 (10.3%) experienced de novo dyspareunia. Minor complications were seen in 15 patients (24%). One developed a symptomatic enterocele. CONCLUSIONS: Interposition of cadaveric fascia lata avoids dependence on weakened native rectovaginal support to facilitate the rectocele repair. Our technique uses fascial interposition, rather than obliteration of the defect, preventing vaginal narrowing, and should thereby decrease the incidence of dyspareunia. Patient symptom improvement and satisfaction rates were competitive with those after traditional rectocele repair. Follow-up is ongoing with the hope that the fascial reinforcement will translate into more durable results.

Direct vision internal urethrotomy for the treatment of pediatric urethral strictures: analysis of 50 patients.

PURPOSE: In an attempt to evaluate our experience with the treatment of pediatric urethral stricture disease we performed a retrospective review of patients undergoing direct vision internal urethrotomy (DVIU). MATERIALS AND METHODS: The computerized surgical logs at 2 pediatric hospitals were reviewed to identify patients who underwent DVIU between 1992 and 2001. Hospital and clinical charts were then reviewed. Many variables were analyzed, including patient age, etiology of stricture, technique and clinical outcomes. Minimum followup to be included in clinical outcome analysis was 12 months. RESULTS: A total of 50 patients were identified (mean age 7.7 years, range 6 months to 17 years). The most common etiology for stricture formation was previous hypospadias repair (20 patients [40%]). Forty patients met the 12-month minimum followup requirement for clinical outcome analysis. Of these patients 20 (50%) had no symptoms to suggest recurrent stricture at a median of 2.0 years (mean 2.7 years, range 12 months to 7 years). Seventeen patients (42.5%) had symptoms of recurrent stricture at a median of 8 months (mean 13 months, range 2 months to 5 years). Technical factors did not influence the ultimate success or failure of the procedure. CONCLUSIONS: DVIU provides a therapeutic option that successfully treats approximately half of the patients with a reasonably low complication rate. Complications following DVIU should not preclude its use as a therapeutic modality for the treatment urethral strictures in children. If the child fails the initial DVIU, repeat attempts at endoscopic correction of urethral stricture should be abandoned in favor of definitive urethroplasty.
