Study of three urethral pressure recording devices: Theoretical considerations
1978
Using a bladder-urethra model, 2 perfusion catheters (open side and open tip) were compared to the balloon catheter. The most accurate results were obtained using the balloon catheter. Based on the law of continuity and Bernouilli's law, the disadvantage of the open side catheter is due to the inconstant diameter of the sum of the side holes. Therefore, the measured pressure is not necessarily identical to the real pressure. The open tip catheter measures the opening pressure and the recorded pressure does not necessarily reflect the pressure at the site of the tip hole. The balloon catheter has elastic and plastic characteristics. Optimum results were obtained only with prestretch of the b…
Rectal cancer threatening or affecting the prostatic plane: is partial prostatectomy oncologically adequate? Results of a multicentre retrospective s…
2015
Aim The management of rectal cancer threatening or affecting the prostatic plane is still under debate. The role of preoperative chemo radiotherapy and the extent of prostatectomy seem to be key points in the treatment of these tumours. The aim of the present study was to evaluate the pathological circumferential margin status and the local recurrence rate following different therapeutic options. Method A multicentre, retrospective study was conducted of patients with rectal cancer threatening or affecting the prostatic plane, but not the bladder, judged by magnetic resonance imaging (MRI). The use of preoperative chemoradiotherapy and the type of urologic resection were correlated with the…
Neourethra: a new two-stage procedure for reconstruction of the functional urethra.
1983
Abstract In 14 male dogs, the functional urethra was replaced by a bladder flap tube in a 2-stage procedure. In the 1st stage of the operation a bipedicle strip from the anterior bladder wall was tubularized around a 10F or 12F catheter. After 10 to 12 weeks the 2nd stage of the procedure was performed: the bladder neck was transected and sutured, and the cranial pedicle of the bipedicle tube was transected and pulled through the bluntly dissected pelvic floor muscles. From the distal end of the tube a perineal urostoma was created to facilitate radiological and urodynamic followup. Eight dogs completed a followup 5 months after the 2nd procedure. Urodynamic and x-ray studies were done preo…
EAU guidelines on the treatment and follow-up of non-neurogenic male lower urinary tract symptoms including benign prostatic obstruction.
2013
To present a summary of the 2013 version of the European Association of Urology guidelines on the treatment and follow-up of male lower urinary tract symptoms (LUTS). We conducted a literature search in computer databases for relevant articles published between 1966 and 31 October 2012. The Oxford classification system (2001) was used to determine the level of evidence for each article and to assign the grade of recommendation for each treatment modality. Men with mild symptoms are suitable for watchful waiting. All men with bothersome LUTS should be offered lifestyle advice prior to or concurrent with any treatment. Men with bothersome moderate-to-severe LUTS quickly benefit from α1-blocke…
Outcome of radical prostatectomy for incidental carcinoma of the prostate
2009
OBJECTIVE To evaluate a contemporary series of patients with incidental prostate cancer detected by transurethral resection of the prostate (TURP) and undergoing radical prostatectomy (RP). PATIENTS AND METHODS Between 1998 and 2004, 1931 patients had TURP for obstructive voiding symptoms and suspected BPH. Incidental prostate cancer was found in 104 (5.4%); 26 of these patients had a RP. The pathological staging and treatment of these patients were reviewed retrospectively and the follow-up results obtained. RESULTS Of the 26 patients who had RP, 17 had T1a and nine had T1b carcinoma of the prostate. After RP, six (35%) in the T1a group had no residual tumour (pT0) and 11 (65%) had pT2 can…
Two-stage transperineal management of posterior urethral strictures or bladder neck contractures associated with urinary incontinence after prostate …
2007
Objectives: The treatment of posterior urethral strictures or bladder neck contracture associated with severe urinary incontinence after prostate surgery and failure of endoscopic treatments is controversial. We report our experience with a transperineal approach in two steps: end-to-end urethroplasty/anastomosis and subsequent artificial urinary sphincter implantation.Methods: Between September 2001 and January 2005, we observed six patients (58-68 yr old), with a combination of severe urinary incontinence and posterior urethral stricture with anastomotic bladder neck contracture after prostate surgery. In all cases, repeated endoscopic treatments of the strictures failed. The patients und…
Risk Factors for Failure of Male Slings and Artificial Urinary Sphincters: Results from a Large Middle European Cohort Study.
2016
<b><i>Introduction:</i></b> We analysed the impact of predefined risk factors: age, diabetes, history of pelvic irradiation, prior surgery for stress urinary incontinence (SUI), prior urethral stricture, additional procedure during SUI surgery, duration of incontinence, ASA-classification and cause for incontinence on failure and complications in male SUI surgery. <b><i>Materials and Methods:</i></b> We retrospectively identified 506 patients with an artificial urinary sphincter (AUS) and 513 patients with a male sling (MS) in a multicenter cohort study. Complication rates were correlated to the risk factors in univariate analysis. Subsequentl…
The TiLOOP® Male Sling: Did We Forejudge.
2017
<b><i>Introduction:</i></b> To evaluate the safety and efficacy of the TiLOOP® male sling (pfm medical, Cologne, Germany) used in the treatment for male stress urinary incontinence (SUI). <b><i>Material and Methods:</i></b> We retrospectively evaluated a total of 34 patients with a TiLOOP® male sling. Perioperative complication rates were assessed and validated questionnaires were prospectively evaluated to assess quality of life and satisfaction rate. Outcome and complication rates were analysed by using descriptive statistics. Correlation of continence outcome and risk factors was performed with the chi-square test. A <i>p</i> va…
Failed hypospadias in paediatric patients
2013
Failed hypospadias refers to any hypospadias repair that leads to complications or causes patient dissatisfaction. The complication rate after hypospadias repairs ranges from 5-70%, but the actual incidence of failed hypospadias is unknown as complications can become apparent many years after surgery and series with lifelong follow-up data do not exist. Moreover, little is known about uncomplicated repairs that fail in terms of patient satisfaction. Risk factors for complications include factors related to the hypospadias (severity of the condition and characteristics of the urethral plate), the patient (age at surgery, endocrine environment, and wound healing impairment), the surgeon (tech…
Lingual mucosal grafts for anterior urethroplasty: a review
2009
We critically reviewed recent reports of lingual mucosal grafts (LMGs) for substitution urethroplasty, to determine the efficacy and complications of this approach. Only a few centres have published the short or interim outcome of LMG urethroplasty. These studies dealt mainly with surgical techniques and harvesting LMGs, emphasizing the comparison of different intra-oral donor sites. The preliminary results seem to be encouraging for the safety and efficacy of LMG urethroplasty. When compared with other substitute materials, LMG give equally good results with much easier harvesting and minimal donor site morbidity. Thus, lingual mucosa is most likely to become an alternative to oral mucosa …
