Vaginal repair of large cystoceles.

Repair of cystoceles requires a complete understanding of the pelvic anatomy. While smaller defects are relatively straightforward, greater degrees of prolapse can be among the most challenging surgeries in pelvic floor reconstruction. This article reviews current transvaginal techniques used for repair of large cystoceles.

A new technique for cystocele repair and transvaginal sling: the cadaveric prolapse repair and sling (CAPS).

A new technique using cadaveric fascia lata for the simultaneous repair of a cystocele and placement of a pubovaginal sling by means of a transvaginal approach is described, and our early results are reported. We refer to this as the cadaveric prolapse repair with sling (CaPS). Fifty patients, ages 37 to 90 years, underwent a new technique for simultaneous cystocele repair and transvaginal pubovaginal sling using a single piece of cadaveric fascia. Maximum follow-up was 6 months (range 1 to 6). A 6 x 8 cm segment of cadaveric fascia lata is placed transvaginally to repair the defect through which the bladder herniates into the vagina and to provide sling support at the bladder neck/proximal urethra. The sling is anchored to the pubic bone with transvaginal bone anchors. The remainder of the fascia is then secured to the medial edge of the levator muscles/pubocervical fascia bilaterally and at the vaginal cuff or cervix with absorbable sutures to reduce the cystocele. Patients are being evaluated with preoperative and postoperative stress, emptying, anatomy, protection, instability (SEAPI) scores as well as with grading of the prolapse based on a 3-grade anatomic classification system. Presenting symptoms have included stress urinary incontinence (SUI) in 13 (26%), urge incontinence in 4 (8%), mixed incontinence in 6 (12%), and pelvic prolapse in 20 (40%). These symptoms are not mutually exclusive; some patients presented with a combination of symptoms. The mean SEAPI scores were 5.51 preoperatively and 0.63 postoperatively, representing a significant improvement (P <0.001). Of the 40 patients whose prolapse was quantified, 1 patient (2.5%) had a minimal cystocele, 16 (40.0%) had moderate cystoceles, and 23 (57.5%) had large cystoceles. After the CaPS, 36 (72%) were completely dry, 3 (6%) had persistent SUI, 1 (2%) had de novo urinary incontinence (UI), 3 (6%) had persistent UI, and 1 (2%) had mixed incontinence. No patient had permanent urinary retention. Transvaginal placement of cadaveric fascia for concomitant sling and cystocele repair provides material of excellent strength for the repair without relying on the inherently weak tissues in the patient with pelvic prolapse. Thus far, the early results with CaPS are extremely encouraging. Long-term follow-up is underway to evaluate the efficacy of this procedure.

Pelvic prolapse.

PURPOSE: Pelvic prolapse is a common problem affecting women of all ages. We reviewed the pathophysiology, presentation, evaluation and treatment of pelvic prolapse. MATERIALS AND METHODS: We comprehensively reviewed the literature using MEDLINE, resources cited in those peer reviewed articles and abstracts from recent international meetings. RESULTS: Pelvic prolapse involves the herniation of various portions of the vaginal wall. Symptoms vary according to the area of the vagina affected. Proper evaluation is imperative for providing proper treatment. Various surgical approaches to repair have been developed and techniques continue to evolve. CONCLUSIONS: With the increasing involvement of urologists in the treatment of pelvic prolapse it is essential for us to become familiar with the anatomy, and the evaluation and management options available. We provide an overview of the care of patients with pelvic prolapse.

Undiagnosed urethral carcinoma: an unusual cause of female urinary retention.

Female urinary retention is extremely rare. Two cases of female urethral carcinoma that presented as urinary retention are reviewed and discussed.

Erosion of woven polyester pubovaginal sling.

PURPOSE: Various materials have been used for pubovaginal slings to correct female stress urinary incontinence. Use of synthetic materials provides a theoretical advantage in that no graft harvesting is necessary. Major risks of synthetic material use are erosion and infection of the sling. We report on erosion of woven polyester slings treated with pressure injected bovine collagen (ProteGen) which required removal. MATERIALS AND METHODS: Office records of patients who had ProteGen slings removed at 5 centers during the last 24 months were retrospectively reviewed. Presenting symptoms, interval between sling placement and removal, subsequent procedures and continence status following sling removal were evaluated. RESULTS: A total of 34 women required removal of the polyester sling secondary to erosion, infection or pain. The most common presenting complaints were delayed vaginal discharge in 21 patients (62%), vaginal pain or pressure in 21 (62%), suprapubic pain in 11 (32%) and recurrent urinary tract infection in 5 (15%) at a mean of 7.95 months (range 1 to 22) after sling placement. Of the patients 17 (50%) had vaginal erosion only, 7 (20%) isolated urethral erosion and 6 (17%) urethrovaginal fistulas. In 4 patients no erosion was obvious but slings were removed secondary to vaginal pain. Before sling removal 16 patients (47%) were totally dry, 13 (38%) had some degree of urinary incontinence and 3 (8%) had retention. Following sling removal 7 patients (20%) remained dry, 25 (74%) had mild to severe stress urinary incontinence with or without urgency and urge incontinence, and 2 (6%) are pending followup. CONCLUSIONS: Woven polyester slings treated with pressure injected bovine collagen are prone to erosion. Although the ProteGen sling was recalled in January 1999, patients who have had the sling placed must be followed closely.

Stress urinary incontinence.

New techniques for the treatment of female stress urinary incontinence are constantly being developed. In assessing treatment modalities, one must consider many variables including patient satisfaction and quality of life, cure or improvement rate, patient selection, and long-term durability of results. In 1998, many papers comparing and examining the outcomes of various new and old techniques were published.

[Criteria of Rigiscan normalcy in aged men]. / Critères de normalité de Rigiscan chez l'homme âgé.

PURPOSE: To define the changes in penile tumescence and rigidity in normally potent older men before a nerve-sparing radical retropubic prostatectomy (NS-RRP) and to establish a base-line for investigating erectile dysfunction in that age group. MATERIAL AND METHODS: 75 patients used the Rigiscan for 2-3 nights before undergoing a NS-RRP procedure. Rigiscan data were analyzed visually using Kaneko & Bradley criteria, and by computerized analysis. The computerized data were compared to the patient self-evaluation of potency (questionnaire), patient's age (above and below 60 years old), peak cavernosal artery velocity measured by Duplex Doppler scanning, and to the visual analysis of the Rigiscan data. RESULTS: 55 of 75 men (73%) completed three sessions. 42 men had at least 2 normal sessions, and when compared to the 33 with abnormal visual tracings, only age was significantly characteristic (p < 0.05). Tip event rigidity (%) in < 60 year-old men was greater than in older men (p < 0.01). Nearly all men had erections lasting more than 2 minutes, while only 29 of 74 had 10 minutes erections with rigidity > 70%. The best correlation between visual and computerized analyses was noted in the group of 54 men who experienced > 70% rigidity for more than 2 minutes. CONCLUSION: This large prospective series of potent older men studied by Rigiscan and other subjective and objective parameters helps establishing normative data in the diagnosis of erectile dysfunction. An important observation is clearly the lack of correlation between the patient's questionnaire or the Doppler findings and the Rigiscan data.

Evaluation of urinary IL-1alpha and IL-1beta in gravid females and patients with bacterial cystitis and microscopic hematuria.

OBJECTIVES: to determine IL-1alpha and IL-1beta levels in patients with bacterial cystitis, microscopic hematuria, and gravid females relative to a control group of normal subjects. METHODS: enzyme immunoassays were used to measure concomitantly urinary IL-1alpha and IL-1beta in clean catch urine samples from normal subjects (n = 31) and study patients (n = 46). All normal subjects and patients underwent urinalysis, urine culture, and urine creatinine level determination. Since the IL-1alpha assay was developed for serum, the utility of the assay for urine specimens was unknown. The key parameters of urine collection, processing and sample storage for IL-1alpha were evaluated in detail. RESULTS: mean values +/- SEM (pg/mg) for IL-1alpha/ Cr and IL-1beta/Cr were control group (0.25 +/- 0.10 and 0.17 +/- 0.06), bacterial cystitis (9.97 +/- 1.15 and 42.45 +/- 1.86), and microscopic hematuria (2.81 +/- 0.65 and 2.82 +/- 0.70). Differences in cytokine levels between the control group and patients with either bacterial cystitis or microscopic hematuria were statistically significant for both IL-1alpha/Cr (P < 0.026; P < 0.007, respectively) and IL-1beta /Cr (P < 0.0004; P < 0.014, respectively). IL-1beta/Cr correlates better with pyuria than IL-1alpha/ Cr (P = 0.02 vs P = 0.44). In gravid females, only IL-1alpha was significantly elevated relative to non-pregnant females (IL-1beta elevation approached statistical significance). Gravid females with positive urine cultures could not be distinguished from those with negative cultures based on either interleukin (P > 0.05). CONCLUSIONS: Significant elevations of IL-1alpha and IL-1beta occur in patients with bacterial cystitis and microscopic hematuria. Correlation between pyuria and cytokine elevation was stronger for IL-1beta than for IL-1alpha. Changes in IL-1alpha may reflect changes in the bladder epithelium rather than in the inflammatory leukocytes. The ability of IL-1alpha and IL-1beta to serve as markers for bacterial cystitis in gravid females is diminished due to high basal levels during pregnancy.

Feasibility of outpatient percutaneous bladder neck suspension under local anesthesia.

OBJECTIVES: To demonstrate the feasibility of outpatient percutaneous bladder neck suspension (BNS) under local anesthesia to treat stress urinary incontinence (SUI) in females. METHODS: Since October 1994, 40 women with SUI (mean age 59.6+/-12.0 years) underwent outpatient percutaneous BNS with "Z" suture anchoring of the anterior vaginal wall and pubocervical fascia. The suspension sutures were secured to percutaneously placed bone anchors. The procedure was performed under local anesthesia. Pain during surgery was evaluated with an analogue scale graded from 0 (no pain) to 5 (severe pain). RESULTS: In 98% of the BNS, the procedure was successfully performed with the patient under local anesthesia. Conversion to general anesthesia was necessary for only 1 patient due to knee pain in the lithotomy position. No major complications were observed. Patients rated their perioperative pain as 1.0+/-0.6 (that is, minimal pain). Patients required pain medications for a mean of 2.4+/-1.3 days postoperatively. Mean duration of recovery (defined by a return to normal activities) was 2.2+/-1.0 weeks; 92% of the patients were continent postoperatively, and no recurrence of urethral hypermobility was observed. CONCLUSIONS: Our results demonstrate the feasibility of outpatient percutaneous BNS performed in patients under local anesthesia without significant morbidity. Continued follow-up will be necessary to determine the long-term efficacy of this procedure.

Results of pubovaginal sling for the treatment of intrinsic sphincteric deficiency determined by questionnaire analysis.

PURPOSE: We evaluated by questionnaire analysis the success rate and overall patient satisfaction after pubovaginal sling surgery. MATERIALS AND METHODS: A total of 40 women (mean age 65.7 years, range 45 to 79) underwent pubovaginal sling surgery for stress urinary incontinence due to intrinsic sphincteric deficiency. Patients completed a detailed questionnaire to assess voiding symptoms, urinary control and satisfaction. Of 40 patients 37 (92.5%) returned the questionnaire, with a mean postoperative followup of 48.2 months (range 24 to 60). RESULTS: Patients with preoperative stress urinary incontinence alone were more likely to be dry than were patients with preoperative mixed incontinence (67% versus 36%, p < 0.001). Ten patients (27%) reported stress urinary incontinence recurrence. Of the patients 23 (62.2%) reported urgency symptoms at followup, with de novo urgency occurring in 4 patients. Permanent retention was noted in 3 patients, including 2 with sacral arc denervation. Overall patients reported 86% postoperative improvement in urinary continence, and 81% would recommend the operation. CONCLUSIONS: At mean 4-year followup after pubovaginal sling surgery, this outcome study using a self administered questionnaire confirms high patient satisfaction despite significant postoperative urgency symptoms.

Female Stress Urinary Incontinence Clinical Guidelines Panel summary report on surgical management of female stress urinary incontinence. The American Urological Association.

PURPOSE: The American Urological Association convened the Female Stress Urinary Incontinence Clinical Guidelines Panel to analyze the literature regarding surgical procedures for treating stress urinary incontinence in the otherwise healthy female subject and to make practice recommendations based on the treatment outcomes data. MATERIALS AND METHODS: The panel searched the MEDLINE data base for all articles through 1993 on surgical treatment of female stress urinary incontinence. Outcomes data were extracted from articles accepted after panel review. The data were then meta-analyzed to produce outcome estimates for alternative surgical procedures. RESULTS: The data indicate that after 48 months retropubic suspensions and slings appear to be more efficacious than transvaginal suspensions, and also more efficacious than anterior repairs. The literature suggests higher complication rates when synthetic materials are used for slings. CONCLUSIONS: The panel found sufficient acceptable long-term outcomes data (longer than 48 months) to conclude that surgical treatment of female stress urinary incontinence is effective, offering a long-term cure in a significant percentage of women. The evidence supports surgery as initial therapy and as a secondary form of therapy after failure of other treatments for stress urinary incontinence. Retropubic suspensions and slings are the most efficacious procedures for long-term success (based on cure/dry rates). However, in the panel's opinion retropubic suspensions and sling procedures are associated with slightly higher complication rates, including longer convalescence and postoperative voiding dysfunction.

Quality of life and continence assessment of the artificial urinary sphincter in men with minimum 3.5 years of followup.

PURPOSE: We determined the long-term efficacy and quality of life impact of the artificial urinary sphincter. MATERIALS AND METHODS: We reviewed the medical records of 68 men who underwent artificial urinary sphincter placement for post-prostatectomy incontinence (64) or neurogenic disease (4) between March 1980 and March 1992 (mean followup 7.2 years). Quality of life was assessed in 52 patients who completed the incontinence impact questionnaire and the urogenital distress inventory. RESULTS: At followup 54 men were socially continent (0 or 1 pad per day). Overall, pad score decreased significantly from 2.75 before to 0.97 after artificial urinary sphincter implantation (p < 0.001). The artificial urinary sphincter was permanently removed in 4 patients. Revisions for mechanical failure or urethral atrophy were required in 25% of the patients (mean 1.35 procedures per patient). The mechanical failure rate decreased significantly after 1987 due to device improvements (12.4 versus 44.4%, p < 0.01). Subjective improvement and overall satisfaction were rated as 4.1 and 3.9, respectively (scale 0 to 5). At followup the mean values of the incontinence impact questionnaire and urogenital distress inventory demonstrated the positive impact of the artificial urinary sphincter on quality of life. CONCLUSIONS: This long-term study documents the positive impact of the artificial urinary sphincter on patient quality of life with few mechanical failures since 1987.

Prospective multicenter ProLase II clinical trial of neodymium:yttrium-aluminum-garnet laser prostatectomy.

OBJECTIVES: To assess the clinical efficacy of neodymium:yttrium-aluminum-garnet (YAG) laser coagulation prostatectomy using a broad-angle, divergent-beam, side-firing fiber. METHODS: Eighty adult men with voiding symptoms caused by benign prostatic hyperplasia were enrolled in a prospective multicenter study of free-beam neodymium:YAG laser prostatectomy performed with the ProLase II side-firing delivery fiber. Voiding outcomes were assessed at 3, 6, and 12 months postoperatively. RESULTS: At 1-year follow-up, peak urinary flow rates were increased by 105%, postvoid residual urine volumes had decreased by 38%, and the AUA symptom index had decreased by 60%. Serious treatment-related complications occurred in 3 of 80 patients (3.8%). The reoperation rate through 1-year follow-up was 2.7%. CONCLUSIONS: Neodymium:YAG laser prostatectomy performed with the ProLase II delivery fiber has proven safe and efficacious with durable results through 1 year in the relief of symptomatic bladder outlet obstruction due to benign prostatic hyperplasia.

[The variability of the leakage pressure threshold due to exertion "the Valsalva Leak Point Pressure" as a function of the filling volume of the bladder]. / Etude de la variabilité du seuil de pression de fuite à l'effort < < Valsalva Leak Point Pressure > > en fonction du volume de remplissage de la vessie.

OBJECTIVE: To determine the influence of the bladder filling volume on the Valsalva Leak Point Pressure (VLPP) in patients investigated for urinary stress incontinence. PATIENTS AND METHODS: 50 patients investigated for urinary stress incontinence were included in this prospective study. Evaluation consisted of clinical examination, urodynamic examination with simultaneous fluoroscopic assessment and cystoscopy. VLPP was measured while standing every 100 cc during filling until the cystomanometric bladder capacity. RESULTS: We observed a significant reduction of VLPP as a function of bladder filling volume. The VLPP measured at 200 cc constituted the reference value in view of its sensitivity and specificity for the diagnosis of type III urinary stress incontinence (Blaivas' classification). CONCLUSION: Measurement of VLPP must be standardized and interpreted as a function of bladder filling volume.

Multiple urinary cytokine levels of bacterial cystitis.

PURPOSE: We have examined urinary cytokine levels to define the inflammatory response in patients with bacterial cystitis or microhematuria relative to normal subjects. Cytokines examined include interleukin-1beta (IL-1beta), IL-1alpha, tumor necrosis factor (TNF alpha), IL-6 and IL-4. Unique features of this study include a) a simultaneous study of several relevant cytokines b) a study of the inflammatory response at both low and high counts of bacterial infection and c) an assessment of whether microhematuria without bacterial cystitis or pyuria is associated with cytokine elevation compared to normals. MATERIALS AND METHODS: Enzyme immunoassays were utilized for each cytokine. Patients studied include those with bacterial cystitis (n = 49), patients with microhematuria (n = 11), and normal subjects (n = 36). Cytokine levels were also determined for patients with low count bacterial cystitis (1,000-50,000 organisms; n = 15) and compared to high count bacterial cystitis (>100,000 organisms; n = 34) and normal subjects. Statistical analysis was carried out using the Kruskal-Wallis test followed by pairwise testing with Newman-Keuls test. RESULTS: a) The means for normal, microhematuria and bacterial cystitis groups were significantly different (p <0.05) for IL-1beta, IL-1alpha, TNF alpha and IL-6, but not for IL-4. b) Except for IL-4, all cytokines were found to be significantly elevated in low count bacterial cystitis compared to normals. No statistically significant difference was observed between low and high count bacterial cystitis groups for any of the cytokines tested. CONCLUSIONS: a) Significant and similar inflammatory responses are present in both low and high count bacterial cystitis groups as compared with the normal group. b) IL-6 and TNF alpha are significantly elevated in patients with microhematuria compared to normals. c) The potential clinical utility of the assays lies in identifying the specific cytokines elevated, understanding the pathways that give rise to their production, and in defining potential virulence factors that may produce significant inflammation at low count bacterial infections.

Urinary stress incontinence due to intrinsic sphincteric deficiency: experience with fat and collagen periurethral injections.

PURPOSE: We prospectively compared the efficacy of 2 bulking agents to treat incontinence related to intrinsic sphincter deficiency. MATERIALS AND METHODS: A total of 67 women underwent periurethral injection for intrinsic sphincter deficiency at the same institution performed by 1 surgeon. Patients were divided into 45 who received fat (group 1) and 22 who received collagen (group 2) injections. Both groups were comparable for age, parity, number of previously failed procedures and number of pads used daily. Preoperative urodynamic evaluation revealed a low Valsalva leak point pressure in both groups (mean plus or minus standard deviation 23.82 +/- 12.41 versus 29.35 +/- 11.32, not significant). Patients rated the subjective degree of postoperative improvement as 0 to 100%. RESULTS: At a mean followup of 7 months after the last injection only 13% of the fat group and 24% of the collagen group were cured. The mean percentage of subjective improvement was significantly greater in the collagen than in the fat group (70.9 +/- 28 versus 31.2 +/- 41.7%, respectively, p < 0.001). The failure rate was significantly greater in the fat group compared to the collagen group (p < 0.001). CONCLUSIONS: Based on results of a prospective comparison of fat and collagen injection, collagen is more effective than fat for treatment of intrinsic sphincter deficiency.

Role of the four-corner bladder neck suspension to correct stress incontinence with a mild to moderate cystocele.

OBJECTIVES: Women undergoing four-corner bladder neck suspension were evaluated for subjective and objective results of the procedure. Patients were evaluated for continence, prolapse, and symptomatic status postoperatively. METHODS: Forty-seven women underwent four-corner bladder neck suspension for moderate cystocele with (44) or without (3) stress urinary incontinence. Mean and median follow-up were 37 months (range 15 to 80). To assess results of the four-corner bladder neck suspension, two sets of outcome measures were used (subjective questionnaire, including patient satisfaction, and objective physical examination, with standing voiding cystourethrogram) to compare pre- and postoperative data. RESULTS: At the time of follow-up, 25 patients (53%) reported no incontinence, 14 (30%) reported one incontinent episode per week, and 8 (17%) reported daily loss of urine. Twenty-seven (57%) had grade I or grade II cystoceles on follow-up examination and voiding cystourethrogram; however, only 12 (26%) experienced recurrent prolapse symptomatology. Overall patient acceptance of the procedure was high (70%). CONCLUSIONS: The four-corner bladder neck suspension is an effective option in the management of moderate cystocele.

Primary bladder neck obstruction: urodynamic findings and treatment results in 36 men.

PURPOSE: We reviewed the urodynamic findings and treatment outcomes of a large series of men with primary bladder neck obstruction. MATERIALS AND METHODS: A retrospective review was done of the presenting symptoms and urodynamic findings of 36 men with primary bladder neck obstruction. Outcomes after treatment with alpha-blockers, transurethral incision of the bladder neck and prostate, or no long-term therapy were determined by chart review and patient survey in the majority of cases. RESULTS: Mean age of the men was 41 years. Patients had significant lower urinary tract symptoms, decreased peak urinary flow rates, elevated post-void residual, markedly elevated peak voiding pressures and poor funneling of the bladder neck during voiding. Although most patients initially chose alpha-blocker therapy, only 30% of those beginning alpha-blockers continued them long term, usually due to inadequate symptomatic improvement. A total of 18 men underwent transurethral incision, which resulted in significant improvements in symptom scores, peak urinary flow rates, post-void residual and peak voiding pressures. Patients reported a mean 87% overall improvement in symptoms after transurethral incision. CONCLUSIONS: Video urodynamics facilitate diagnosis of primary bladder neck obstruction. Transurethral incision is the most effective therapy for primary bladder neck obstruction.
