ABSTRACT: Objective: To evaluate prospectively the value of the 'repositioning test' (RT) in preoperative patient selection for the efficacy of male stress urinary incontinence (SUI) treatment using a retroluminar transobturator male sling (AdVance sling). Patients and Methods: 65 consecutive patients with SUI after radical prostatectomy were included in this single-center prospective study. Preoperatively, patients were classified into those with 'positive' and 'negative' RT. Postoperative results were analyzed and the association between the result of the RT and postoperative outcome was evaluated. Results: 53 patients (81.5%) showed preoperatively a positive RT and 12 patients (18.5%) a negative RT. After a follow-up of 12 months, patients with positive RT showed a cure rate (0 pads/day) of 83% and patients with a negative RT showed only a cure rate of 25%. A positive RT significantly correlated with cure in outcome (p < 0.001). Conclusions: Patients with positive RT have a significantly better chance for successful AdVance sling implantation. The RT is minimally invasive, easy to learn and easy to perform. Therefore, the RT is a very useful tool for preoperative patient selection.

ABSTRACT: PURPOSE: We prospectively evaluated changes in morphology and dynamics of the male pelvic floor on magnetic resonance imaging (MRI) associated with retrourethral transobturator sling (RTS) placement. PATIENTS AND METHODS: Twenty-six men with post-prostatectomy incontinence consecutively underwent functional cine-MRI before and 12 months after RTS. The membranous urethra length (MUL) and severity of periurethral/urethral fibrosis were assessed on static MRI. A lowering of the posterior bladder wall (BPW), the bladder neck (BN), the external urinary sphincter (EUS) and symphysial rotation of these structures were analysed on dynamic MR images. The success rate was defined as cure (0-1 dry 'security' pad) or improvement (pad reduction ≥50 %). RESULTS: The success rate was 77 % (20/26 patients). The mean follow-up was 20.4 months. The MUL significantly increased post-operatively (p < 0.001). There were no significant pre- and post-operative differences in severity of periurethral/urethral fibrosis. Significant elevation of the BPW (p < 0.021), BN and EUS (p < 0.002) was observed post-operatively. The RTS failure was significantly associated with the severity of periurethral fibrosis pre- (p < 0.032) and post-operatively (p < 0.003). CONCLUSIONS: RTS placement is associated with MUL increase, elevation of the BN, BPW and EUS. De novo development of periurethral or urethral fibrosis seems not to be confirmed. The RTS failure was related to the severity of pre- and post-operative periurethral fibrosis. The impact of MRI on pre-operative diagnostics of RTS failure needs further evaluation.

ABSTRACT: The AdVance male sling (American Medical Systems, Minnetonka, MN, USA) has been shown to be an efficacious device in short-term studies for postprostatectomy incontinence (PPI), but long-term studies are lacking.
Examine the intermediate-term outcome with the AdVance sling for PPI management.
A multicentre prospective evaluation was conducted on consecutive patients treated for PPI in three European tertiary reference centres.
Patients were implanted with the AdVance male sling with no associated surgery. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Measurements included daily pad usage, maximum flow rate (Qmax), postvoid residual urine (PVR), the International Consultation on Incontinence Questionnaire-Short Form, the Incontinence Quality of Life questionnaires, and complications of surgery. Paired Wilcoxon signed rank test univariable and multivariable analyses were used.
Follow-up was available for 156 patients for the majority of parameters. Pad usage was significantly decreased compared with baseline at 12 mo and 3 yr (p<0.0001). At 12 mo, 76.9% of patients could be classified as cured or improved; this percentage was maintained at 3 yr (76.8%). Cure rates (58.6% vs 42.3%) and improvement rates (23.2% vs 25.0%) were higher in patients with mild or moderate incontinence compared with severe incontinence. Univariable analysis showed that pretreatment pad usage and severity of incontinence were both significant predictors of success (p=0.0355 and p=0.0420, respectively). However, in multivariable analysis, only pad usage was an independent predictor of success. There were no perioperative or severe postoperative complications. Most complications were Dindo grade I. Seven patients required a second treatment for stress urinary incontinence. There was no worsening over time. Limitations of this study included no comparator group, quality of life questionnaires in only two centres, and no 24-h pad test.
The transobturator retroluminal repositioning sling suspension is effective and safe in the longer term for treating PPI.

ABSTRACT: OBJECTIVE: To evaluate the validity of a single-stage dorsal inlay for recurrent peno-glandular stenosis following previous endourological or open urethroplastic surgery. Urethral glanular reconstruction included a deep dorsal incision followed by complete scar excision to create a deep groove presenting well-vascularized recipient bed ensuring appropriate graft healing. MATERIALS AND METHODS: Between April 2002 and January 2008, a total of 34 patients (mean age 51.5 years, 14-85 years) were enrolled in the study. Congenital anomalies included hypospadia (n = 19, 53%) and epispadia (n = 2, 6%). Condition of strictures was either iatrogenic (n = 7), due to infection (n = 5), or traumatic (n = 1). Foreskin grafts were used in 13 cases, foreskin and buccal mucosa in one case, penile skin in 6 cases, and inguinal skin/thigh (harvested by electrodermatom) in 14 cases. The combination of meticulous scar excision with a deep incision of the glans was used to provide a well-vascularized grafting bed, thus ensuring excellent graft healing. The outcome analysis included urinary flow, urethral calibration >18 ch, voiding cystometry, and patient's satisfaction in a follow-up regime every 3 months. RESULTS: The average graft length was 4.7 cm (median 8, range 1.5-14). Mean follow-up was 70 months. In 31 patients (91%), no recurrent glanular stenosis was observed resulting in a post-operative flow of average 26.2 ml/s (11-53). Three post-operative wound infections occurred resulting in stricture recurrence, which was treated with internal urethrotomy, buccal mucosa, or penile skin inlay, respectively. Cosmetic results were satisfactory in all patients. Post-operative voiding parameters were significantly improved (P < 0.001). CONCLUSION: The single-stage dorsal inlay for reconstruction of peno-glandular stenosis represents a reliable method even if the urethral plate is severely scarred or has been excised during previous surgery. The good results imply that a well-vascularized graft and the technical approach seem to be more important than the substitute material.

ABSTRACT: The aim of this study was to correlate anatomic differences with continence status in male patients after cystoprostatectomy and ileal neobladder using real-time magnetic resonance imaging.
Anatomic differences of 14 male patients (7 daytime continent and 7 stress incontinent) with ileal neobladder were determined by measuring the orthogonal distance of the bladder neck to the pubococcygeal line (PCL) to correlate anatomic differences with continence status.
The median distance of the bladder neck to PCL was +5.4 mm in continent patients before voiding whereas in incontinent patients it was +2 mm (p = 0.012). During the Valsalva maneuver, the median distance in continent patients was +4 and in incontinent patients -3 mm (p = 0.003). At the end of micturition, the median distance was +2.3 mm in continent patients and -12 mm in incontinent patients (p = 0.002).
The bladder neck in incontinent patients showed more pronounced mobility in relation to the PCL during micturition and the Valsalva maneuver as compared to continent patients. In addition, the ileal neobladder was positioned significantly lower in the pelvis of incontinent patients. These preliminary results suggest that a stable bladder neck may be an important factor to reach full continence in patients with ileal neobladder.

ABSTRACT: To evaluate prospectively detailed urodynamic parameters before and after retrourethral transobturator sling (RTS) placement and the impact of adverse preoperative urodynamic parameters on postoperative outcome.
Fifty-five consecutive patients with postprostatectomy stress urinary incontinence (SUI) underwent urodynamics with pressure flow and abdominal leak point pressure (ALPP) measurements, quality of life, 1-hour pad test, and daily pad use assessment before RTS (AdVance) and 12 months postoperatively. Volume of first sensation and first desire to void, maximum cystometric capacity (MCC), ALPP, maximum flow rate (Qmax.), average flow rate, time to Qmax., detrusor voiding pressure at Qmax., voiding time, and postvoid residual urine volume (PVR) were assessed. The success rate was defined as cure (no or one dry "security" pad) or improvement (1-2 pads or pad reduction≥50%). Adverse parameters included ALPP≤30 cm H2O, Qmax.≤10 mdL/s, and MCC≤200 mL.
Success rate after RTS was 73% (40/55 patients). Mean follow-up was 21±11.7 (range, 12-41) months. Only ALPP changed significantly (61±14.2 vs 79±20.4 cm H2O). No PVR>30 mL, de novo reduced bladder compliance and hypo- or overactivity were observed. Urine loss by 1-hour pad test (136.1±119.4 vs 39.4±77.0) and daily pad use (4.6±2.0 vs 1.9±2.1) decreased significantly. Adverse preoperative urodynamic parameters were not associated with postoperative outcome.
The RTS is an effective and safe device for SUI treatment without signs of compression or obstruction of the urethra or any influence on voiding parameters. Adverse preoperative urodynamic parameters have no influence on postoperative outcome.

ABSTRACT: To investigate the interactions between the bladder, urethra, pelvic floor and the function of the prostate during 'normal' voiding.
In all, 16 men with no history of urinary incontinence, urgency or obstructive voiding dysfunction were enrolled. We analysed the interaction between the bladder, urethra, pelvic floor and changes in the prostate during the Valsalva manoeuvre and voiding using real-time magnetic resonance imaging (rtMRI). The axis through the external sphincter (AES) to pubo-coccygeal line (PC-line) and the angle between the axis of the os pubis (AOP) and ventral prostate (VP) was measured before and at the end of voiding. Additionally, the angle between the AOP and the VP was measured during the Valsalva manoeuvre. Change of position, or contraction, of the VP was measured.
The mean age of the men was 69.8 years and mean prostate volume 33.1 mL. Before voiding, the mean AES to PC-line was 10.5 mm. At the end of voiding, the mean AES to PC-line was 20 mm. The mean angle between AOP/VP was 31.6° in the storage phase and increased to a mean of 54.5° during voiding. During the Valsalva manoeuvre, the angle between the AOP/VP remained constant. There was a mean vertical contraction of the VP of 48.25 mm before voiding and a declining of the cranio-caudal distance of the VP with a mean of 33.92 mm during voiding.
All the men in our study showed relaxation of the pelvic floor, followed by a descent of the bladder neck. Voiding could not be initiated unless the prostate rotated around the symphysis. The study suggests that both the rotation and a vertical contraction of the prostate precede voiding. The anatomy of physiological voiding or voiding dysfunction can be investigated non-invasively using rtMRI.

ABSTRACT: In recent years, despite improvement in the surgical technique, the prevalence of postprostatectomy incontinence has increased due to a rise in the number of radical prostatectomies performed annually.
The aim of this review is to evaluate contemporary noninvasive and invasive treatment options for postprostatectomy incontinence.
In August 2010, a review of the literature was performed using the Medline database.
All articles concerning noninvasive and invasive treatment for postprostatectomy incontinence were included.
No randomised controlled trials exist to compare currently used noninvasive and invasive treatments for postprostatectomy incontinence. Pelvic floor muscle training is recommended for the initial treatment of stress urinary incontinence (SUI). Additionally, antimuscarinic therapy should be applied for urgency or urge incontinence. For decades, the artificial urinary sphincter was the reference standard for persistent SUI. Nowadays, male slings are an alternative for men with mild to moderate postprostatectomy SUI.

ABSTRACT: Prospective evaluation of independent risk factors for failure of the retrourethral transobturator sling suspension (RTS) with special attention on sphincter function and surgical technique.
A total of 189 patients with postprostatectomy stress urinary incontinence (SUI) were treated with RTS (AdVance(®) sling) in a prospective clinical study with a mean follow-up of 20.8 months. Eleven patients were lost to follow-up. Uni- and multivariate analyses were performed to identify independent risk factors for RTS failure. The success rate was defined as cured (no pad use or one dry 'security' pad) or improved (one to two pads and pad reduction ≥ 50%).
At a mean follow-up of 20.8 months, the overall success rate was 73.1%. Multivariate analysis revealed that weak residual function and incomplete closure of the sphincter (OR, 29.0), no elongation of the coaptive sphincter zone (OR, 26.9), no sling tunnelling (OR, 22.6) and use of resorbable sutures with a small number (≤ 4) of stitches (OR, 8.4) are significant predictors for RTS failure.
Preoperative selection of the patients with regard to residual sphincter function and a special attention on better sling fixation may increase RTS efficacy.

ABSTRACT: To prospectively evaluate the efficacy of the functional AdVance transobturator sling for the treatment of male stress urinary incontinence (SUI) in patients after radical prostatectomy and additional adjuvant radiotherapy.
Between February 2007 and November 2008, 24 patients with postprostatectomy SUI (ICS grade 2-4) and additional adjuvant radiotherapy were treated consecutively with the AdVance sling. Preoperatively, intensive workup, including urodynamic assessment and flexible urethroscopy, was performed. Physical examinations (pad test, uroflowmetry, ultrasound) and questionnaires (I-QOL score, ICIQ-UI-SF score) were performed during baseline and during follow-up. Cure rate was defined as no pad use or one dry pad, and improved rate as 1-2 pads or reduction of pads by ≥50%.
After a median follow-up of 18.0 months (range 12-33 months, mean 18.8 months), the success rate was 50%. Daily pad use and pad weight in the 1-hour pad test decreased significantly. Patients with ICS grade 2 SUI exhibited a trend for a better success rate in comparison with patients with grade 3 and 4 SUI. Results were durable over time. Postoperatively, 16.7% of the patients exhibited transient acute urinary retention which resolved without further treatment after a maximum of 6 weeks. 1 sling had to be removed because of initial misplacement.
In selected patients after adjuvant radiotherapy, the AdVance sling achieved a success rate of 50% and results were stable in a median follow-up of 18 months. Complication rates were low and comparable to complication rates for patients without additional radiotherapy.

ABSTRACT: α1-Adrenoceptors are considered critical for the regulation of prostatic smooth muscle tone. However, previous studies suggested further α1-adrenoceptor functions besides contraction. Here, we investigated whether α1-adrenoceptors in the human prostate may activate extracellular signal-regulated kinases (ERK1/2).
Prostate tissues from patients undergoing radical prostatectomy were stimulated in vitro. Activation of ERK1/2 was assessed by Western blot analysis. Expression of ERK1/2 was studied by immunohistochemistry. The effect of ERK1/2 inhibition by U0126 on phenylephrine-induced contraction was studied in organ-bath experiments.
Stimulation of human prostate tissue with noradrenaline (30 μM) or phenylephrine (10 μM) resulted in ERK activation. This was reflected by increased levels of phosphorylated ERK1/2. Expression of ERK1/2 in the prostate was observed in smooth muscle cells. Incubation of prostate tissue with U0126 (30 μM) resulted in ERK1/2 inhibition. Dose-dependent phenylephrine-induced contraction of prostate tissue was not modulated by U0126.
α1-Adrenoceptors in the human prostate are coupled to ERK1/2. This may partially explain previous observations suggesting a role of α1-adrenoceptors in the regulation of prostate growth.

ABSTRACT: The aim of the study was a prospective assessment of patient-reported side effects in an open-label study after intradetrusor botulinum toxin injections for idiopathic overactive bladder (OAB).
Botulinum toxin A injection was performed in 56 patients with idiopathic OAB. Patients were followed up for 6 months concerning side effects and patients' satisfaction.
Different types of side effects were assessed such as dry mouth (19.6%), arm weakness (8.9%), eyelid weakness (8.9%), leg weakness (7.1%), torso weakness (5.4%), impaired vision (5.4%) and dysphagia (5.4%). In all cases, symptoms were mild and transient. Urological complications such as gross hematuria (17.9%), acute urinary retention (8.9%) and acute urinary tract infection (7.1%) were noticed. In all cases, acute urinary retention was transient and treated with temporary intermittent self-catheterization. There was no statistically significant correlation between dosage and observed side effects. Patients' satisfaction rate was high (71.4%).
Intradetrusor injection of botulinum toxin was associated with a high rate of neurourological side effects. In general, side effects were transient, mild and did not require special treatment.

ABSTRACT: A failure rate between 20% and 45.5% after retrourethral transobturator sling (RTS) is reported. Recommendations for the management of persistent or recurrent postprostatectomy stress urinary incontinence (SUI) after failed male sling do not exist.
The aim of this study was the prospective evaluation of the efficacy of repeat RTS (RRTS) in patients after failed first RTS.
Between March 2007 and August 2009, 35 patients with mild to severe SUI after failed first RTS were treated with a second AdVance sling (American Medical Systems, Minnetonka, MN, USA).
Preoperative and postoperative evaluation included daily pad use, 1-hr pad test, postvoiding residual (PVR) urine, uroflowmetry, and quality-of-life (QoL) scores.
After 6 mo, 45.5% (15 of 33 patients) showed no pad use; 30.3% (10 of 33 patients), one dry "security" pad; 3% (1 of 33 patients), one wet pad; 6.1% (2 of 33 patients), two pads; 3% (1 of 33 patients), pad reduction ≥50%; and 12.1% (4 of 33 patients), treatment failure. After 16.6 mo, 34.5% (10 of 29 patients) showed no pad use; 37.9% (11 of 29 patients), one dry "security" pad; 3.4% (1 of 29 patients), one wet pad; 3.4% (1 of 29 patients), two pads; 10.3% (3 of 29 patients), pad reduction ≥50%; and 10.4% (3 of 29 patients), treatment failure. Daily pad use and pad weight decreased significantly. PVR and uroflowmetry results showed no significant change. QoL improved significantly. Postoperative acute urinary retention was observed in 23.6% of patients.
RRTS is an effective and safe treatment option for the management of SUI after failed first RTS.
