Comparison of clinical outcomes between "ideal" and "nonideal" transobturator male sling patients for treatment of postprostatectomy incontinence.

OBJECTIVE: To review the clinical outcomes of "ideal" vs "nonideal" postprostatectomy stress urinary incontinence (PPI) patients who underwent male sling placement. METHODS: The medical records of 95 consecutive patients with PPI who underwent male sling insertion (AdVance male sling, American Medical Systems, Minnetonka, MN) were reviewed. Patients were divided into "ideal" vs "nonideal" cohorts. The ideal group consisted of patients with mild to moderate incontinence (<4 pads/day or <300 g daily pad weight), ability to volitionally contract the external urinary sphincter, no history of pelvic radiation or cryotherapy, no history of previous anti-incontinence surgical procedures, the ability to generate a volitional detrusor contraction when voiding, and a postvoid residual urine volume <100 mL. Patients in the nonideal group did not satisfy all these criteria. RESULTS: Significant reductions in daily pad usage and weight were noted in both cohorts. In the ideal patient group, 66 of 72 patients (92%) would undergo the procedure again. Conversely, only 7 of 23 nonideal men (30%) would undergo the procedure again. CONCLUSION: Preoperative patient selection can influence favorable outcomes after the treatment of PPI with AdVance male slings. Attention to ideal vs nonideal patient characteristics should be used when counseling men considering male sling surgery.

Long-term results of suprapubic bladder neck closure for treatment of the devastated outlet.

OBJECTIVES: To assess the long-term success of suprapubic bladder neck closure in patients with irreparably damaged bladder outlets. METHODS: A cohort of 35 patients with intractable urinary incontinence secondary to severe posterior urethral/bladder neck damage underwent suprapubic bladder neck closure. Patients were assessed with regard to the success of procedure, as well as early and late complications. RESULTS: With a mean follow-up of 79 months (range 12 to 164), suprapubic bladder neck closure was successful in 29 (83%) of 35 patients. One revision of the bladder neck improved the success rate to 94% (33 of 35). Early and late complications, excluding bladder neck fistula, were reported in 3 (9%) and 5 (14%) of 35 patients, respectively. CONCLUSIONS: High success and acceptable complication rates can be achieved with suprapubic bladder neck closure for the treatment of severe urinary incontinence secondary to a devastated bladder outlet.

The influence of age on quality of life outcome in women following a tension-free vaginal tape procedure.

PURPOSE: Tension-free vaginal tape (TVT) has been introduced and demonstrated to be an effective treatment for stress urinary incontinence. Improved general health in the elderly population has led to a greater number of patients seeking surgical treatment for incontinence. We evaluated the impact of TVT on quality of life in elderly patients, defined as age 70 and older. MATERIALS AND METHODS: We prospectively evaluated 67 patients with genuine stress incontinence differentiated by age into 2 groups, namely 21 who were 70 years and older, and a control group of 46 younger than 70 years, with a validated questionnaire. We assessed quality of life changes following TVT for incontinence treatment. RESULTS: At the most recent followup quality of life scores improved significantly in the 2 groups (p <0.05). Stress incontinence improved significantly in the 2 groups (p <0.05). CONCLUSIONS: TVT is effective in each group. It is a viable treatment option to improve quality of life in older women with stress urinary incontinence.

Cadaveric fascia lata pubovaginal slings: early results on safety, efficacy and patient satisfaction.

OBJECTIVE: To prospectively evaluate and quantify the efficacy of cadaveric fascia lata (CFL) as an allograft material in pubovaginal sling placement to treat stress urinary incontinence (SUI). PATIENTS AND METHODS: Thirty-one women with SUI (25 type II and six type III; mean age 63 years, range 40-75) had a CFL pubovaginal sling placed transvaginally. The operative time, blood loss, surgical complications and mean hospital stay were all documented. Before and at 4 months and 1 year after surgery each patient completed a 3-day voiding diary and validated voiding questionnaires (functional inquiry into voiding habits, Urogenital Distress Inventory and Incontinence Impact Questionnaire, including visual analogue scales). RESULTS: The mean (range) operative time was 71 (50-120) min, blood loss 78.7 (20-250) mL and hospital stay 1.2 (1-2) days; there were no surgical complications. Over the mean follow-up of 13.5 months, complete resolution of SUI was reported by 29 (93%) patients. Overactive bladder symptoms were present in 23 (74%) patients before surgery, 21 (68%) at 4 months and two (6%) at 1 year; 80% of patients with low (< 15 cmH2O) voiding pressures before surgery required self-catheterization afterward, as did 36% at 4 months, but only one (3%) at 1 year. Twenty-four (77%) patients needed to adopt specific postures to facilitate voiding. After surgery there was a significant reduction in daytime frequency, leakage episodes and pad use (P < 0.05). The severity of leak and storage symptoms was also significantly less (P < 0.002), whilst the severity of obstructive symptoms remained unchanged. Mean subjective levels of improvement were 69% at 4 months and 85% at 1 year, with corresponding objective satisfaction levels of 61% and 69%, respectively. At 1 year, approximately 80% of the patients said they would undergo the procedure again and/or recommend it to a friend. CONCLUSION: Placing a pubovaginal sling of CFL allograft is a highly effective, safe surgical approach for resolving SUI, with a short operative time and rapid recovery. Storage symptoms are significantly improved, and subjective improvement and satisfaction rates are high.

Artificial urinary sphincter implantation in the irradiated patient: safety, efficacy and satisfaction.

OBJECTIVE: To compare the long-term outcome of artificial urinary sphincter (AUS) implantation in patients after prostatectomy, with and with no history of previous irradiation. PATIENTS AND METHODS: The study included 98 men (mean age 68 years) with urinary incontinence after prostatectomy for prostate cancer (85 radical, 13 transurethral resection) who had an AUS implanted. Twenty-two of the patients had received adjuvant external beam irradiation before AUS implantation. Over a mean (range) follow-up of 46 (5-118) months, the complication and surgical revision rates were recorded and compared between irradiated and unirradiated patients. The two groups were also compared for the resolution of incontinence and satisfaction, assessed using a questionnaire. RESULTS: Overall, surgical revision was equally common in irradiated (36%) and unirradiated (24%) patients. After activating the AUS, urethral atrophy, infection and erosion requiring surgical revision were more common in irradiated patients (41% vs. 11%; P < 0.05); 70% of patients reported a significant improvement in continence, regardless of previous irradiation. Patient satisfaction remained high, with > 80% of patients stating that they would undergo surgery again and/or recommend it to others, despite previous irradiation and/or the need for surgical revision. CONCLUSIONS: Despite higher complication and surgical revision rates in patients who have an AUS implanted and have a history of previous irradiation, the long-term continence and patient satisfaction appear not to be adversely affected.

Non-invasive antidromic neurostimulation: a simple effective method for improving bladder storage.

Patients with intractably diminished bladder storage function are encountered frequently by neurourologists, occasionally requiring reconstructive surgery for appropriate resolution. Although sacral neuromodulation is a recognized effective therapeutic modality, present techniques are technically demanding, invasive, and expensive. This study investigated the effect of non-invasive third sacral nerve (S3) stimulation on bladder activity during filling cystometry. One hundred forty-six patients underwent standard urodynamic filling cystometry that was then immediately repeated. Patients in the study group (n = 74) received antidromic transcutaneous sacral neurostimulation during the second fill and the control group (n = 72) underwent a second fill without neurostimulation. A statistically significant increase in bladder storage capacity without a corresponding rise in detrusor pressure was observed in the neurostimulated patients. This improvement in functional capacity is an encouraging finding that further supports the use of this non-invasive treatment modality in clinical practice.

Vaginal wall sling: long-term outcome analysis of factors contributing to patients satisfaction and surgical success.

PURPOSE: The clinical outcome of the vaginal wall sling was retrospectively evaluated to determine patient perception, satisfaction and factors contributing to postoperative success. MATERIAL AND METHODS: An outcome based study was conducted of 51 patients undergoing construction of a vaginal wall sling for genuine stress incontinence or intrinsic sphincteric deficiency. Preoperative symptoms, demographic parameters and video urodynamic studies were correlated with postoperative patient perception of symptoms to determine patient satisfaction and factors contributing to overall success. RESULTS: Of 42 patients (82%) available for followup 31 (74%) reported improvement in continence, 26 (62%) are currently satisfied with the urinary status, 72% in retrospect would repeat the procedure and 69% would recommended the vaginal wall sling to others. Despite long-term resolution of stress incontinence in 92% of those with genuine stress incontinence and 75% with intrinsic sphincter deficiency, postoperative urge incontinence was the single most important factor affecting patient satisfaction (p = 0.001). Patients without postoperative urge incontinence enjoyed the greatest levels of satisfaction, in excess of 90% (p = 0.001). Although preoperative leak point pressure correlated with resolution of stress incontinence, no preoperative demographic factors, symptoms or urodynamic parameters could reliably predict postoperative patients satisfaction. CONCLUSIONS: The vaginal wall sling represents an excellent option for the treatment of genuine stress incontinence and an acceptable option of intrinsic sphincteric deficiency. Patient perception and satisfaction remain closely associated with presence or resolution of postoperative urge incontinence. However, prediction of postoperative urge incontinence remains a challenge and should be considered when counseling patients preoperatively.

Urodynamic findings in the tethered spinal cord syndrome: does surgical release improve bladder function?

PURPOSE: We retrospectively reviewed 39 patients with a tethered spinal cord to evaluate whether surgical release positively influenced urological symptoms or urodynamic findings. MATERIALS AND METHODS: The patients were divided into 2 groups: group 1-11 with occult spinal dysraphism and group 2-28 with secondary spinal cord tethering after previous closure of a myelomeningocele or resection of a lipomyelomeningocele. Diagnosis was confirmed in all cases by magnetic resonance imaging or spinal ultrasound. A comprehensive urodynamic evaluation was done immediately preoperatively and 2 to 21 months (mean 7) postoperatively. RESULTS: In group 1 the most common preoperative urodynamic finding was hyperreflexia, which improved or resolved after untethering in 62.5% of the patients. Four adults also reported improved bladder sensation or decreased urgency. In group 2 the most common urodynamic finding was impaired compliance, followed closely by detrusor hyperreflexia. Urodynamic patterns of detrusor hyperreflexia or compliance improved in only 30% of the patients, while 48% had worsened patterns. Only 14% of group 2 had improved symptoms of urinary control but 28% had improved lower extremity function. CONCLUSIONS: Urological symptoms and urodynamic patterns may be improved by early surgical intervention in patients with occult spinal dysraphism. However, untethering did not consistently benefit patients with secondary spinal cord tethering.

[Orthotopic replacement of the bladder]. / Sostituzione ortotopica della vescica.

The Davis technique has been used in 42 male patients with invasive bladder cancer, node-negative, and no bladder neck or prostatic involvement with TCC. Patients were told before the operation that there might be occasional difficulties with voiding and nocturnal incontinence, and that catheterisation might sometimes be necessary. All had undergone cysto-prostatectomy and bilateral pelvic lymphadenectomy. A 40 cm segment of ileum with the most dependent mesentery was used to make the urethro-ileal anastomosis. It was placed in a U-shaped configuration and the back wall closed with absorbable staples. Using electro-cautery, the segment was opened to gain access to the anterior staples, which were then removed. The segment was then folded up to form a conventional Kock pouch, with two corners. Finally the anterior portion was closed with absorbable staples or sutures. After three months approximately 95% of patients remained dry during the daytime and 75% at night. A total of 90% of patients were highly satisfied with the outcome, dissatisfaction relating mainly to incontinence and the need to catheterize.

[Continent urinary diversion]. / Derivazione urinaria continente.

The Davis procedure is a modification of Indiana pouch, using a stapling technique and a right colon segment. The ileo-caecal valve is reinforced in a slightly different way from the Indiana procedure, but the terminal ileum is similarly tapered. An umbilical stoma is created since many patients are obese and the umbilicus is the thinnest part of the abdominal wall. The technique has been used in 22 patients, and there have been few complications. Continence is generally excellent, but patients tend to leak at capacity (this, however, indicates to patients when they should catheterize). Overall patient satisfaction is excellent.

Post-prostatectomy incontinence and the artificial urinary sphincter: a long-term study of patient satisfaction and criteria for success.

PURPOSE: We investigated patient satisfaction with the artificial urinary sphincter and established criteria for a successful outcome by inquiring about patient perceived satisfaction, continence achieved and comparison with the surgeon office records. MATERIALS AND METHODS: During 9 years 65 patients with post-prostatectomy incontinence underwent placement of the AMS800 artificial urinary sphincter. Review of charts and a telephone questionnaire were conducted to determine patient perceived satisfaction. RESULTS: A total of 50 patients participated in the survey. Median followup was 23.4 months. Preoperative incontinence was severe. Of the patients 90% reported continuous leakage, and 70% wore an average of 6 diapers and 24% wore an average of 7.4 pads daily. The long-term complete continence rate was 20%. Of the patients with wetness 55% had leakage of a few drops daily and 22% had leakage of less than a teaspoon. Of all patients 50% had leakage daily, 24% had leakage 1 or more times a week and wore an average of 1.5 pads per day, and 6% reported changing clothes due to wetness. A total of 90% of the patients reported satisfaction with the artificial urinary sphincter and 96% stated that they would recommend or had recommended the artificial urinary sphincter to a friend. In retrospect, 92% of the patients would have the artificial urinary sphincter placed again, 90% of those undergoing revision reported no change in satisfaction and 14% reported improved sexual activity. CONCLUSIONS: Patient satisfaction with the artificial urinary sphincter for post-prostatectomy incontinence is uniformly high. Although postoperative continence was not 100%, relative improvement in continence was the most significant factor affecting patient perceived outcome. Using these parameters criteria for a successful outcome can be established, and patient concerns regarding the artificial urinary sphincter can be dispelled.

Upper urinary tract videourodynamics: a more complete Whitaker test.

A modification of the Whitaker test is described using only a single nephrostomy tube for both inflow and pressure measurement. The technique also includes ureteral transit time and fluoroscopic imaging. This technique has been used in ten patients, all of whom had symptoms and/or imaging suggesting obstruction. Five patients had no obstruction on testing with true renal pelvic pressures 20cm. This technique requires only one access port into the renal pelvis. The addition of fluoroscopy and ureteral transit time considerably aided our interpretation of the test. These modifications have made the Whitaker test more complete.

Proximal artificial sphincter cuff repositioning for urethral atrophy incontinence.

OBJECTIVES: Recurrent incontinence after implantation of an artificial urinary sphincter (AUS) may be due to urethral atrophy. Treatment options consist of decreasing the cuff size, increasing the balloon pressure, implanting a double-cuff system, or proximal cuff repositioning. The first three options may increase the risk of erosion. Increasing the balloon pressure does not effectively increase cuff pressure. This article demonstrates that proximal cuff repositioning is a safe, simple, and effective technique in the management of recurrent incontinence as a result of a loss of cuff compression due to urethral atrophy. METHODS: Six patients underwent proximal repositioning of the AUS (AS-800) cuff for recurrent post-prostatectomy incontinence. Urethral atrophy was determined by a thorough systematic evaluation. A detailed description of the surgical technique is provided. RESULTS: Five of 6 patients (83%) had significant improvement in incontinence with an average follow-up of greater than 1 year. In 1 patient with no improvement, preoperative urodynamics revealed poor detrusor compliance in addition to sphincter weakness due to loss of cuff compression. CONCLUSIONS: Proximal cuff repositioning on the bulbar urethra is an effective, safe, and simple technique in the management of recurrent incontinence due to urethral atrophy and may minimize the risk of erosion.

Neurourologic evaluation and urologic management of spinal dysraphism.

The urologic management of the spina bifida child has evolved considerably over the past 10 years. Clinicians now more fully understand the nature of the bladder dysfunction and are therefore able to modify this behavior by either conservative or surgical measures. The spina bifida child and parents can now be confident that the bladder can be appropriately rehabilitated with significant improvement in quality of life.

Urodynamic comparison of ileum vs. sigmoid in augmentation cystoplasty for neurogenic bladder dysfunction.

We performed multichannel urodynamics before and after augmentation cystoplasty in 26 patients (11 females, 15 males) to determine which bowel segment is best to achieve a large volume and low pressure reservoir. All 26 patients had a neurogenic cause for their bladder dysfunction. Ileum was used in 14 patients and sigmoid was used in 12 patients. Detubularization was performed in all patients. Capacity improved significantly in both the ileum and the sigmoid group after surgery. When detubularized ileum was used, the maximum amplitude of uninhibited reservoir contractions was significantly improved or eliminated postoperatively. When sigmoid was used, uninhibited reservoir contractions did not significantly improve postoperatively and were, in fact, more common than preoperatively. Despite the detubularization, pressure waves were identified in 15 of the 26 patients postoperatively. There was significant improvement in end filling pressures at capacity (compliance) with both ileum and sigmoid postoperatively. However, end filling pressures were significantly higher in the sigmoid group. In conclusion, good capacity was achieved with both ileum and sigmoid postoperatively. However, ileum provided lower reservoir pressures and better compliance. We feel that urodynamically detubularized ileum is better suited than sigmoid for augmentation cystoplasty in patients with neurogenic bladder dysfunction.
