In our experience polypropylene mesh used as a broad based tension-free sling was successful for treating all types of SUI. In our opinion technique and case selection have a bearing on outcomes.
In patients treated for bladder outlet obstruction secondary to benign prostatic hyperplasia 23% of the stents were removed, as were 5% of those implanted in patients with bulbar urethral stricture and 22% of those in patients with detrusor-sphincter dyssynergia (see figure). Of the explantations 43.8% were done during year 1. Migration and/or inappropriate placement was the cause in 38.4% of cases. The most common stent site tissue finding was focal inflammation with a hyperplastic tissue response. Stent specific malignant changes were not observed. Stent removal was feasible with no sequelae. CONCLUSIONS When used appropriately, the UroLume endoprosthesis has a low incidence of failure. Stent removal is technically feasible and options are available for subsequent therapy. Local tissue reaction is minimal.
Objective:The urethral gap in pelvic fracture urethral injury (PFUI) is traditionally assessed using voiding cystourethrogram (VCUG) and retrograde urethrogram (RGU). Magnetic resonance imaging (MRI) is performed in complex cases. We assessed the refined "Joshi" MRI protocol to evaluate complex urethral defects after PFUI.
Material and methods:A prospective study was conducted at our center from January 2018 to January 2020, involving patients aged >18 years with PFUI, suitable for MRI, and those who gave consent to perform standard RGU, VCUG, and MRI using standard and "Joshi" protocol. Forty men were included in the study. Distance between urethral/prostatic stumps was measured. Image quality was scored by four radiologists and four urologists. The surgical approach and type of PFUI repair were noted. We also established the need for inferior pubectomy by assessing the position of the posterior urethra (membranous) in relation to a horizontal line drawn from the lower edge of the pubic bone anteriorly to the rectum posteriorly in a sagittal image.
Results:The mean age was 30 years (SD, 5.25; range, 21-43), and the time from injury to imaging was 4 months (3-10 months); 40% of the men underwent crural separation, 57.5%, inferior pubectomy, and 2.5%, crural rerouting. There was a difference of 0.3 to 1.1 cm in the urethral gap measurements between MR images using the standard versus "Joshi" technique. MRI identified complex injuries such as rectourethral fistula, the need for inferior pubectomy, and the orientation of the posterior urethra. Urologists' and radiologists' satisfaction scores for the MR images were satisfactory to excellent. If the posterior urethra was over the defined mark, there was a 100% likelihood of inferior pubectomy (23/40 patients).Conclusion: MR image acquisition using the "Joshi" protocol provided high-quality anatomical information in PFUI cases to assist with surgical planning.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
